• SQL SERVER – SSMS 2012 Reset Keyboard Shortcuts to Default

  - by pinaldave

  As a technologist, I love my laptop very much and I do not lend it to anyone as I am usually worried that my settings would be messed up when I get it back from its borrower. Honestly, I love how I have set up my laptop and I enjoy the settings and programs I have placed on my computer. If someone changes things there – it will surely be annoying for me. Recently at one of the conferences I was attending in, a small accident happened – one of the speaker’s hard drives failed. The owner immediately panicked due to this and had no clue what to do. I suggested that he may not be able to show the demos but can still show a few things with the product. He accepted my suggestion and finished the presentation. Good thing everybody looked satisfied. Little did I know that a small accident was waiting for me later that day. When I opened my SQL Server Denali, all my shortcuts were totally out of order. When I hit F5, instead of executing query, it was opening up some debugging screen for me. I was very much annoyed so I decided to surf the Internet for me to know how I could reset it to SQL Server 2012 default shortcut. There were so many different advices which further confused me. After reading 4-5 different methods, I used the following method to reset my SQL Server 2012 keyboard shortcuts: Go to SSMS > Tools >> Import and Export Settings… As I wanted to reset all the settings I selected the “Reset all settings” option, but you can select other options as per your need. I suggest you save your current Settings; however, in my case, I did not like the current option so I just decided to overwrite my settings. Here I have two options –  I can either set my shortcut to SQL Server 2012 settings or Visual Studio 2010. I went ahead with the SQL Server 2012 option. Success!

• Upgrading TFS 2005 to TFS 2010 fails at "Executing servicing step Upgrade Version Control Identities"

  - by nadeemmar

  Hi all, I have been trying to upgrade our TFS 2005 to TFS 2010 but with no luck so far. I went through the TFS Installation guide and many upgrade guides but with no luck in overcoming the issue I am facing which seems to be unique and different to other described issues. In our company, we have a domain forest with several domains. Lets say domain A, B, and C. TFS is in domain A and has users from all these three domains. All domains have trust reltionships between them. However, domain C was deleted several months ago. In the upgrade process, whenever I reach the collection upgrade step, the following error is raised: [Info @09:57:50.997] [2010-12-29 09:55:47Z][Informational] Step Data: ExtensionType = Microsoft.TeamFoundation.VersionControl.Server.PlugIns.WorkspaceSecurityNamespaceExtension [Info @09:57:50.997] [2010-12-29 09:55:47Z] Servicing step Create VersionControl Security Namespaces passed.

With a bit of googling, I figured out that TFSConfig Identities command can be used to remap users from one domain to the other. I went ahead and created local users that matches the users we have from domain C and ran the TFSConfig Identities /Change command and it executed successfully. However, I still get the same error. I am stuck and can't figure out how to move forward :( I need your expertise, has anyone faced this issue before? Do I need to change these identities on TFS 2005 before I commence the upgrade? I forgot to mention, I am following the upgrade with a move approach. I created a virtual machine for testing the upgrade. Installed SQL server 2008, restored the TFS databases and installed TFS 2010 and ran the upgrade wizard. Regards, Nadeem

• SQL Server 2005 FREETEXT() Perfomance Issue

  - by Zenon

  I have a query with about 6-7 joined tables and a FREETEXT() predicate on 6 columns of the base table in the where. Now, this query worked fine (in under 2 seconds) for the last year and practically remained unchanged (i tried old versions and the problem persists) So today, all of a sudden, the same query takes around 1-1.5 minutes. After checking the Execution Plan in SQL Server 2005, rebuilding the FULLTEXT Index of that table, reorganising the FULLTEXT index, creating the index from scratch, restarting the SQL Server Service, restarting the whole server I don't know what else to try. I temporarily switched the query to use LIKE instead until i figure this out (which takes about 6 seconds now). When I look at the query in the query performance analyser, when I compare the ´FREETEXT´query with the ´LIKE´ query, the former has 350 times as many reads (4921261 vs. 13943) and 20 times (38937 vs. 1938) the CPU usage of the latter. So it really is the ´FREETEXT´predicate that causes it to be so slow. Has anyone got any ideas on what the reason might be? Or further tests I could do?

• Server 2008 Disk Management Hangs

  - by Payson Welch

  So I have looked everywhere for the solution to this and have tried many things. There is one post on SE related to this and I tried the suggested answer but I am still having problems. We have a server running Server 2008 R2 Standard x64. I need to increase the space of C: since the free space is running very low. However when I open Server Manager and try to go to the "Disk Management" snap-in it just hangs. There is a status message on the bottom of the window that says "Connecting to Virtual Disk Service...". Here are the steps I have taken: Ran sfc /scannow Set all of the drives to be dirty and rebooted so that they would be scanned Executed chkdsk /f /r /b /v on all of the drives. Checked for Windows updates (none). Verified that the services "Virtual Disk", "RPC Procedures" and "Plug and Play" are all running. One symptom is that the service "Virtual Disk" does not cleanly shut down. I receive a message about the process being unexpectedly terminated when I try to stop or restart it. Also I cannot find anything relevant in the event logs. Any ideas or suggestions?

• in HFT trading should I upgrade from Windows Server 2008 R2 to Windows Server 2012?

  - by javapowered

  I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012. I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency http://msdn.microsoft.com/library/windows/hardware/jj248719 http://technet.microsoft.com/en-us/library/hh831415.aspx Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2. So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?

• Unable to start SQL Server Instance 2008 R2 - DB file corrupt

  - by Velu

  I was not able to start the SQL Server 2008 R2 production DB instance. After reading the log file error message is " The log scan number passed to log scan in database ‘master’ is not valid.

• Server 2003 R2 doesn't allow logon after a few days of uptime

  - by Bryan

  We have a server 2003 R2 standard (which I'll refer to as SRV01) that's knocking on a bit now, but it still acts as a file, print and SQL server on our company's network. SRV01 hosts user profiles, home directories and pretty much all our business data. Note our AD is currently at 2008 R2 level. This server is due to be upgraded in the next 12 months, but I've no budget to spend on it just yet. A bit of history of this server follows: When SRV01 was first commissioned, it acted as a domain controller (with the same 2003 R2 install it has today), paired with another server that ran Server 2003 R2 SBS. A few years ago, we purchased a pair of dedicated DCs (2008 R2) and at this point we decommissioned the 2003 SBS server, and SRV01 was DCPROMOed out of the AD. Up until very recently, SRV01 used to run Exchange 2003, however we've recently purchased a dedicated server for Exchange 2010 and upgraded (following Microsoft recommended upgrade path). Exchange 2003 was recently uninstalled. - Cleanly to the best of my knowledge. Ever since Exchange was removed from SRV01, I'm finding that after a few days of uptime, when I attempt to logon, pressing CTRL-ALT-DEL just hides the Welcome to Windows Server 2003 banner, and never presents the logon dialog. All I see is a moveable mouse pointer and a blank background. It's a similar story with an admin TS session, the RDP client connects and gives me a blank background, but no logon dialog is presented. The RDP session indefinitely hangs until I give up and close it. The only way I've been able to gain access to the server is to pull the plug on it. Whilst the server does have a battery backed up RAID 5 controller, I'm unhappy about having to do this, so as a temporary measure, I've created a scheduled job to reboot SRV01 each night. Not only do I not like the idea of scheduling a reboot of a server like this, but it is also causing problems for users that leave desktop PCs left logged on overnight. Users complain of 'Delayed Write Failures', and there has also been a number of users that have started to complain about account lockout problems, as well as users not able to connect to shares on SRV01 until they reboot their desktop PCs. I've examined event logs on SRV01 and on the DCs looking for clues as to what the problem is, but there really is nothing untoward being logged. How could I being to investigate this problem when nothing of any relevance is being logged? Is there some additional logging that can be enabled that might give some clues as to what could be causing this problem? Could performance monitor help me out here, and if so, what counters would you consider monitoring? It's worth mentioning that whilst the server is unresponsive via the console and TS, it does still respond to clients connecting to shares without problems for several days, but after about a week I then start to hear users reporting problems accessing shares, but this seems quite sporadic. I've also tried leaving the console logged on (and locked), when I notice I can no longer logon via TS, I can unlock the server console without problem, but it refuses to reboot/shutdown, and subsequent attempts to reboot report that a system shutdown is already in progress and the system then completely hangs. I've tried playing the waiting game for several hours thinking that a timeout might allow the shutdown to continue, but to no avail.

• Virtual Win XP Mode stopped HP LJ Pro M1212nf MFP printing in Win 7 Pro

  - by Dee

  Virtual Win XP Mode stopped HP LJ Pro M1212nf MFP printing in Win 7 Pro: I am running Windows 7 Pro with Virtual Windows XP Mode. My printer is HP LaserJet Pro M1212nf MFP attached directly to a USB port of the computer. This printer was working fine in Windows 7, until I tried to attach the printer to the Virtual Windows XP Mode in order to load the printer driver in the Virtual Windows XP Mode. At that point, the printer disappeared from the list of USB devices on the toolbar at the top of the window of the Virtual Windows XP Mode. After installing the printer driver in the Virtual Windows XP Mode, the printer did not work in that mode and also no longer worked in Windows 7. In Windows 7 and in the Virtual Windows XP Mode, print files are sent to the print queue, but are never printed. In Windows 7, the print queue states that the printer is offline. In the Virtual Windows XP Mode, the printer can be toggled from "Print Offline" to "Print Online", but no print files are ever printed from the print queue. The printer acts as though it is no longer connected to the computer, even though it is still physically connected to the USB port of the computer. How can I get the printer to work again in Windows 7? (At this point, I am no longer interested in using the Virtual Windows XP Mode.) I have tried a large number of things to find and fix the printer problem, but have had no success. Device Manager cannot see the printer even though it is physically connected via USB port (have tried different USB ports) to the computer. Restoring Win 7 and Virtual Win XP Mode to times before the problem does not fix the problem. How can I get the computer to see the printer, so that I can print again in Win 7?

• Cannot get SCVMM Admin Console to Connect to Hyper-V Server 2008 R2

  - by user63250

  I cannot get SCVMM Admin console to connect to Hyper-V Server 2008. I have changed all firewall settings on the server to allow for a connection, I have even tried turning the firewall off completely. I am getting this error message: Unable to connect to the Virtual Machine Manager server xx.xxx.xxx.xx. the Virtual Machine Manager service on that servier did not respond. Verify that Virtual Machine Manager has been installed on the server and that the Virtual Machine Manager service is running. Then try to connect again. If the problem persists, restart the Virtual Machine Manager Service. ID: 1602 I have tried restarting the VMMS service, and that did not work. I have posted a similar question to this before, and was told to make sure to intall the Hyper-V agent on the Hyper-V server. I was told that SCVMM can push the agent out to the server. However, if I cannot connect to the server, how can I use SCVMM to push out the agent? Thanks for any help.

• Server 2008 R2 How to Change Windows 7 Basic Theme Color

  - by Wes Sayeed

  We're deploying thin clients connecting to a terminal server farm. The computers have high visibility to the public and I would like them to at least look presentable and not like something out of 1995. So I installed the Desktop Experience feature and enabled the Theme service. The server will not support Aero because it has no 3D graphics, but we can enable the Windows 7 Basic theme, which has the Aero look without the 3D effects. The problem with that theme is that you can select any window color you want, as long as it's baby boy blue. Is there a way to make those windows another color? The window color controls do nothing.

• Server 2008 R2 DNS Lockup / Stops Resolving Internet Names

  - by Richard Maynard

  We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed

• Forms authentication failed between web server and sql server

  - by Matt Bear

  I've actually found the solution, but I'm trying to understand why it failed, and why my solution fixed the problem. We have an application that uses forms authentication between a web server and sql server, web server runs server 2008, sql server runs 2008 r2, and sql server 2008. In august the sql server was patched with .net 3.5.1, the web server was untouched, and the forms authentication continued to work. 1 week ago we virtualized the web server onto our vSphere server because of failing hardware. Afterwards the form authentication failed with event code 4005, detail code 50201, The ticket supplied was invalid (on the sql server). In fact the sql server started generating Schannel errors and began blue screening 3-4 times a day. At this point I touched the sql server for the first time(ever), the errors were non specific, any reference to them I could find had to do with either zone alarm(which we don't run), or memory errors. So I applied service pack 1, which stopped the blue screening, but did not fix the forms authentication. At this point we had a work around, so we put it on the back burner while we completed another project, and I was able to get back on it last night. First thing was to adjust some code in the webconfig file on the sql server, nothing, next was regenerate and change out the machine key, still no change. Update the DNS servers, no change. Finally I went through and installed all windows updates, two reboots, (over RDP installed a network card driver which failed, and did not have my server room key, that was fun). After that, forms authentication was working again. And the sql server stopped generating as many errors, I've gotten two schannel errors since then. In short, forms authentication began failing when the web server was cloned onto a virtual machine, which caused the sql server to blue sceen? and forms authentication to fail. And could only be fixed by applying patches to the sql server?(I'm wishing I had patched the servers one at a time so I could know for sure which patch on which server fixed it). My question is why did it fail, and why did patching fix it? I hate fixing something without fully understanding the why and how.

• SQL SERVER – Discard Results After Query Execution – SSMS

  - by pinaldave

  The first thing I do any day is to turn on the computer. Today I woke up and as soon as I turned on the computer I saw a chat message from a friend. He was a bit confused and wanted me to help him. Just as usual I am keeping the relevant conversation in focus and documenting our conversation as chat. Let us call him Ajit. Ajit: Pinal, every time I run a query there is no result displayed in the SSMS but when I run the query in my application it works and returns an appropriate result. Pinal:  Have you tried with different parameters? Ajit: Same thing. However, it works from another computer when I connect to the same server with the same query parameters? Pinal: What? That is new and I believe it is something to do with SSMS and not with the server. Send me screenshot please. Ajit: I believe so, let me send you a screenshot, Pinal: (looking at the screenshot) Oh man, there is no result-tab at all. Ajit: That is what the problem is. It does not have the tab which displays the result. This works just fine from another computer. Pinal: Have you referred Nakul’s blog post – SSMS – Query result options – Discard result after query executes, that talks about setting which can discard the query results after execution. (After a while) Ajit: I think it seems like on the computer where I am running the query my SSMS seems to have the option enabled related to discarding results. I fixed it by following Nakul’s blog post. Pinal: Great! Quite often I get the question what is the importance of the feature. Let us first see how to turn on or turn off this feature in SQL Server Management Studio 2012. In SSMS 2012 go to Tools >> Options >> Query Results > SQL Server >> Results to Grid >> Discard Results After Query Execution. When enabled this option will discard results after the execution. The advantage of disabling the option is that it will improve the performance by using less memory. However the real question is why would someone enable or disable the option. What are the cases when someone wants to run the query but do not care about the result? Matter of the fact, it does not make sense at all to run query and not care about the result. The matter of the fact, I can see quite a few reasons for using this option. I often enable this option when I am doing performance tuning exercise. During performance tuning exercise when I am working with execution plans and do not need results to verify every time or when I am tuning Indexes and its effect on execution plan I do not need the results. In this kind of situations I do keep this option on and discard the results. It always helps me big time as in most of the performance tuning exercise I am dealing with huge amount of the data and dealing with this data can be expensive. Nakul’s has done the experiment here already but I am going to repeat the same again using AdventureWorks Database. Run following T-SQL Script with and without enabling the option to discard the results. USE AdventureWorks2012 GO SELECT * FROM Sales.SalesOrderDetail GO 10 After enabling Discard Results After Query Execution After disabling Discard Results After Query Execution Well, this is indeed a good option when someone is debugging the execution plan or does not want the result to be displayed. Please note that this option does not reduce IO or CPU usage for SQL Server. It just discards the results after execution and a good help for debugging on the development server.

• How can I turn a column name into a result value in SQL Server?

  - by Brennan

  I have a table which has essentially boolean values in a legacy database. The column names are stored as string values in another table so I need to match the column names of one table to a string value in another table. I know there has to be a way to do this directly with SQL in SQL Server but it is beyond me. My initial thought was to use PIVOT but it is not enabled by default and enabling it would likely be a difficult process with pushing that change to the Production database. I would prefer to use what is enabled by default. I am considering using COALESCE to translate the boolean value to the string that value that I need. This will be a manual process. I think I will also use a table variable to insert the results of the first query into that variable and use those results to do the second query. I still have the problem that the columns are on a single row so I wish I could easily pivot the values to put the column names in the result set as strings. But if I could easily do that I could easily write the query with a sub-select. Any tips are welcome.

• How to write to a varchar(max) column using ODBC

  - by andyjohnson

  Summary: I'm trying to write a text string to a column of type varchar(max) using ODBC and SQL Server 2005. It fails if the length of the string is greater than 8000. Help! I have some C++ code that uses ODBC (SQL Native Client) to write a text string to a table. If I change the column from, say, varchar(100) to varchar(max) and try to write a string with length greater than 8000, the write fails with the following error [Microsoft][ODBC SQL Server Driver]String data, right truncation So, can anyone advise me on if this can be done, and how? Some example (not production) code that shows what I'm trying to do: SQLHENV hEnv = NULL; SQLRETURN iError = SQLAllocEnv(&hEnv); HDBC hDbc = NULL; SQLAllocConnect(hEnv, &hDbc); const char* pszConnStr = "Driver={SQL Server};Server=127.0.0.1;Database=MyTestDB"; UCHAR szConnectOut[SQL_MAX_MESSAGE_LENGTH]; SWORD iConnectOutLen = 0; iError = SQLDriverConnect(hDbc, NULL, (unsigned char*)pszConnStr, SQL_NTS, szConnectOut, (SQL_MAX_MESSAGE_LENGTH-1), &iConnectOutLen, SQL_DRIVER_COMPLETE); HSTMT hStmt = NULL; iError = SQLAllocStmt(hDbc, &hStmt); const char* pszSQL = "INSERT INTO MyTestTable (LongStr) VALUES (?)"; iError = SQLPrepare(hStmt, (SQLCHAR*)pszSQL, SQL_NTS); char* pszBigString = AllocBigString(8001); iError = SQLSetParam(hStmt, 1, SQL_C_CHAR, SQL_VARCHAR, 0, 0, (SQLPOINTER)pszBigString, NULL); iError = SQLExecute(hStmt); // Returns SQL_ERROR if pszBigString len > 8000 The table MyTestTable contains a single colum defined as varchar(max). The function AllocBigString (not shown) creates a string of arbitrary length. I understand that previous versions of SQL Server had an 8000 character limit to varchars, but not why is this happening in SQL 2005? Thanks, Andy

• How does C#'s DateTime.Now affect query plan caching in SQL Server?

  - by Bill Paetzke

  Given: Let's say we have a stored procedure. It reports data back to a user on a webpage. The user can set a date range. If the user sets today's date as the "end date," which includes today's data, the web app passes DateTime.Now to the sql proc. Let's say that one user runs a report--5/1/2010 to now--over and over several times. On the webpage, the user sees "5/1/2010" to "5/4/2010." But the web app passes DateTime.Now to the sql proc as the end date. So, the end date in the proc will always be different, although the user is querying a similar date range. Assume the number of records in the table and number of users are large. So any performance gains matter. Hence the importance of the question. Question: Does passing DateTime.Now as a parameter to a proc prevent SQL Server from caching the query plan? If so, then is the web app missing out on huge performance gains? Possible Solution: I thought DateTime.Today.AddDays(1) would be a possible solution. It would allow the user to get the latest data and always pass the same end date to the sql proc--"5/5/2010" in this case. Please speak to this as well. Sample proc and execution (if that helps to understand): CREATE PROCEDURE GetFooData @StartDate datetime @EndDate datetime AS SELECT * FROM Foo WHERE LogDate >= @StartDate AND LogDate < @EndDate Here's a sample execution using DateTime.Now: EXEC GetFooData '2010-05-01', '2010-05-04 15:41:27' -- passed in DateTime.Now Here's a sample execution using DateTime.Today.AddDays(1) EXEC GetFooData '2010-05-01', '2010-05-05' -- passed in DateTime.Today.AddDays(1) The same data is returned for both procs, since the current time is: 2010-05-04 15:41:27.

  Question: Does passing DateTime.Now as a parameter to a proc prevent SQL Server from caching the query plan? If so, then is the web app missing out on huge performance gains? Possible Solution: I thought DateTime.Today.AddDays(1) would be a possible solution. It would pass the same end-date to the sql proc (per day). And the user would still get the latest data. Please speak to this as well. Given Example: Let's say we have a stored procedure. It reports data back to a user on a webpage. The user can set a date range. If the user sets today's date as the "end date," which includes today's data, the web app passes DateTime.Now to the sql proc.

• SQL SERVER – Simple Demo of New Cardinality Estimation Features of SQL Server 2014

  - by Pinal Dave

  SQL Server 2014 has new cardinality estimation logic/algorithm. The cardinality estimation logic is responsible for quality of query plans and majorly responsible for improving performance for any query. This logic was not updated for quite a while, but in the latest version of SQL Server 2104 this logic is re-designed. The new logic now incorporates various assumptions and algorithms of OLTP and warehousing workload. Cardinality estimates are a prediction of the number of rows in the query result. The query optimizer uses these estimates to choose a plan for executing the query. The quality of the query plan has a direct impact on improving query performance. ~ Souce MSDN Let us see a quick example of how cardinality improves performance for a query. I will be using the AdventureWorks database for my example. Before we start with this demonstration, remember that even though you have SQL Server 2014 to see the effect of new cardinality estimates, you will need your database compatibility mode set to 120 which is for SQL Server 2014. If your server instance of SQL Server 2014 but you have set up your database compatibility mode to 110 or any other earlier version, you will get performance from your query like older version of SQL Server. Now we will execute following query in two different compatibility mode and see its performance. (Note that my SQL Server instance is of version 2014). USE AdventureWorks2014 GO -- ------------------------------- -- NEW Cardinality Estimation ALTER DATABASE AdventureWorks2014 SET COMPATIBILITY_LEVEL = 120 GO EXEC [dbo].[uspGetManagerEmployees] 44 GO -- ------------------------------- -- Old Cardinality Estimation ALTER DATABASE AdventureWorks2014 SET COMPATIBILITY_LEVEL = 110 GO EXEC [dbo].[uspGetManagerEmployees] 44 GO Result of Statistics IO Compatibility level 120 Table ‘Person’. Scan count 0, logical reads 6, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Employee’. Scan count 2, logical reads 7, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Worktable’. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Worktable’. Scan count 2, logical reads 7, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Compatibility level 110 Table ‘Worktable’. Scan count 2, logical reads 7, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Person’. Scan count 0, logical reads 137, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Employee’. Scan count 2, logical reads 7, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Table ‘Worktable’. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. You will notice in the case of compatibility level 110 there 137 logical read from table person where as in the case of compatibility level 120 there are only 6 physical reads from table person. This drastically improves the performance of the query. If we enable execution plan, we can see the same as well. I hope you will find this quick example helpful. You can read more about this in my latest Pluralsight Course.

• Virtual Earth / Bing maps javascript file size

  - by Aquinas

  I am working with a site that uses virtual earth for its mapping. Unfortunately the file size of the referenced javascript file, ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2, is 200 something kb before being expanded (to 970kb). As our site runs under https this file is not cached on the client, and can cause a few seconds delay to users, made more substantial in times of high load. My question is, is there anyway to get virtual earth to run smaller, or have more efficient lazy loading? At the moment it looks like our hands are tied.

• SQL SERVER – DATE and TIME in SQL Server 2008

  - by pinaldave

  I was thinking about DATE and TIME datatypes in SQL Server 2008. I earlier wrote about the about best practices of the same. Recently I had written one of the script written for SQL Server 2008 had to run on SQL Server 2005 (don’t ask me why!), I had to convert the DATE and TIME datatypes to DATETIME. Let me run quick demo for the same. DECLARE @varDate AS DATE DECLARE @varTime AS TIME SET @varDate = '10/10/2010' SET @varTime = '12:12:12' SELECT CAST(@varDate AS DATETIME) C_Date SELECT CAST(@varTime AS DATETIME) C_Time As seen in example when DATE is converted to DATETIME it adds the of midnight. When TIME is converted to DATETIME it adds the date of 1900 and it is something one wants to consider if you are going to run script from SQL Server 2008 to earlier version with CONVERT.
