• Can I select a set of Data and directly insert that into a table in SQL?

  - by VJ

  Hi I guess we cannot do this but was just curious if I could do something like - Select * from Employee where EmployeeId=1 and then use the data in the above statement and directly insert into a table with just changing the employeeid...or just this way- insert into Employee ( Select * from Employee where EmployeeId=1) its probably stupid from my side...but I just felt the need to do this a lot of times...so just was curious if there was any way to achieve it..

• Get mutually and non mutually existening Fields in same table in Two columns

  - by ranabra

  This is a question similar to another question I posted here but is a little different. I am trying to get a list of all instances of mutual and non-mutual existing Users. What I mean is that the returned result from the query will return a list of users along with their co-worker. It is similar to the question here, but the difference is that non mutual users will be returned too and with out the "duplicity" mutually existing users return in the list (See image below in-order simplify it all). I took the original answer from Thomas (Thanx again Thomas) Select D1.u_username, U1.Permission, U1.Grade, D1.f_username, U2.Permission, U2.Gradefrom tblDynamicUserList As D1    Join tblDynamicUserList As D2        On D2.u_username = D1.f_username            And D2.f_username = D1.u_username    Join tblUsers As U1        On U1.u_username = D1.u_username    Join tblUsers As U2        On U2.u_username = D2.u_username and after some several trials I commented out 2 lines (Below). The returned result are exactly as described in the beginning of this question, but with the "duplicity" returned by mutually existing users in the table. How can I eliminate this duplicity? Select D1.u_username, U1.Permission, U1.Grade, D1.f_username, U2.Permission, U2.Gradefrom tblDynamicUserList As D1    Join tblDynamicUserList As D2        On D2.u_username = D1.f_username            /* And D2.f_username = D1.u_username */    Join tblUsers As U1        On U1.u_username = D1.u_username    Join tblUsers As U2        On U2.u_username = D2.u_username /* WHERE D1.U_userName < D1.f_username */ *Screenshot that hopefully helps explain it all. Database is SQL 2005. Many thanx in advance

• Power error handling inside of sql function

  - by user172062

  I have a power function call inside of a sql function. What is the correct way to handle overflow and underflow conditions since I cannot use a Try Catch inside of a function. I am also trying to avoid modifying the ARITHABORT, ANSI_WARNINGS, and ARITHIGNORE settings in the calling code. GO CREATE FUNCTION TestPow() RETURNS DECIMAL(30, 14) AS BEGIN DECLARE @result FLOAT SET @result = POWER(10.0, 300) RETURN @result END GO SELECT dbo.TestPow()

• Autocomplete server-side implementation

  - by toluju

  What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.

• Override Linq-to-Sql Datetime.ToString() Default Convert Values

  - by snmcdonald

  Is it possible to override the default CONVERT style? I would like the default CONVERT function to always return ISO8601 style 126. Steps To Reproduce: DROP TABLE DATES; CREATE TABLE DATES ( ID INT IDENTITY(1,1) PRIMARY KEY, MYDATE DATETIME DEFAULT(GETUTCDATE()) ); INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; SELECT CONVERT(NVARCHAR,MYDATE) AS CONVERTED, CONVERT(NVARCHAR(4000),MYDATE,126) AS ISO, MYDATE FROM DATES WHERE MYDATE LIKE'Feb%' Output: CONVERTED ISO MYDATE --------------------------- ---------------------------- ----------------------- Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Linq-to-Sql calls CONVERT(NVARCHAR,@p) when I cast ToString(). However, I am displaying all my data in the ISO8601 format. I would like to override the database default if possible to CONVERT(NVARCHAR,@p,126). I am using Dynamic Linq-to-Sql as demoed by ScottGu to process my data. PropertyInfo piField = typeof(T).GetProperty(rule.field); if (piField != null) { Type typeField = piField.PropertyType; if (typeField.IsGenericType && typeField.GetGenericTypeDefinition().Equals(typeof(Nullable<>))) { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.Value.ToString().Contains(\"{1}\")", rule.field, rule.data)); } else { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.ToString().Contains(\"{1}\")", rule.field, rule.data)); } } I was hoping my property would convert the expression from CONVERT(NVARCHAR,@p) to CONVERT(NVARCHAR,@p,126), however I get a NotSupportedException: ... has no supported translation to SQL. public string IsoDate { get { if (SUBMIT_DATE.HasValue) { return SUBMIT_DATE.Value.ToString("o"); } else { return string.Empty; } } }

• Simple Self Join Query Bad Performance

  - by user1514042

  Could anyone advice on how do I improve the performance of the following query. Note, the problem seems to be caused by where clause. Data (table contains a huge set of rows - 500K+, the set of parameters it's called with assums the return of 2-5K records per query, which takes 8-10 minutes currently): USE [SomeDb] GO SET ANSI_NULLS

• w2k3 AD DC Demotion fails with "no other AD DC for that domain can be contacted"

  - by Kstro21

  i've a small office with a single w2k3 sp2 DC(bad idea, but it is real), now, i want to make a clean install of that pc, so, i got another one, install w2k3 sp2, add it to the domain, dcpromo and set it to be a GC, untill now everything is ok, then tried to dcpromo in the primary DC, but it fails with The box indicating that this domain controller is the last controller for the domain mydomain.com is unchecked. However, no other Active Directory domain controllers for that domain can be contacted. Do you wish to proceed anyway? If you click Yes, any Active Directory changes that have been made on this domain controller will be lost. So, i started to move all the roles to the new server as described here, when all was ok with the roles, i tried doing the same, but got the same result. Tried moving the DNS to the new server, but it doesn't make difference. Shutdown to the old server, then tried to log into a workstation, but it fails saying the domain is not available, also coudln't add new workstation to the domain, so i have to power on the old server again. So, if i successfully move all the roles and dns to the new server: why dcpromo give such message in the old server? why if i shutdown the old server the domain is not available?? if i successfully move all the roles and dns to the new server, and i click yes when dcpromo give warning in the old server, will i lose all users, computers, ou, etc.? am i missing some steps to make this work?? hope you can help me thanks

• Delphi Client-Server Application using Firebird 2.5 embedded connection error

  - by Japster

  0 down vote favorite 1 share [fb] share [tw] I have got a lengthy question to ask. First of all Im still very new when it comes to Delphi programming and my experience has beem mostly developing small single user database applications using ADO and an Access database. I need to take the transition now to a client server application and this is where the problem starts. I decided to use Firebird 2.5 embeded as my database, as it is open source, and it is can be used with the interbase components in Delphi and that multiple clients can access the database simultanously. So I followed the interbase tutorial in Delphi. I managed to connect the client to the server and see the data in the example (While both are running on my pc), but when i tried to move the client to another pc, keeping the server on mine and running it to see if I can connect to the server it gave me the following error. Exception EIdSocketError in module clientDemo.exe at 0029DCAC. Socket Error # 10061 Connection refused. I understand that this might be because the host is defined as localhost in the client. But here is my first question. In the TSQLConncetion you can set die hostname under Driver-Hostname. The thing I want to know is how do you do this at run time, as I cannot get the property when I try and make an edit box to allow the user to enter the value and then set it via code like for example: SQLConncetion1.Driver.Hostname := edtHost.text; This cannot be done this way and the only way I see you can set the hostname is with the object inspector, but that is not available at runtime and I need to set the hostname on the client when the program is running the first time, so how do you set the hostname/IP address at runtime? Im using Delphi XE2 There is still a lot of questions to come especially when it comes to deployment, but I will take this piece by piece and I appreciate the advice.

• Debug Deserialization on Silverlight Client

  - by Andrew Garrison

  I'm working on a Silverlight client that interacts with a WCF web service. The Silverlight client and the WCF web service are using the same class library for their data entities that they are passing back and forth over the wire. I just added a new entity, and it's not being correctly deserialized on the Silverlight client. My question is, how can I debug the System.ServiceModel.ClientBase as it is deserializing an entity that it received from a WCF web service?

• FTS: Searching across multiple fields 'intelligently'

  - by Wild Thing

  Hi, I have a SP using FTS (Full Text Search). I want searches across multiple fields, 'intelligently' ranking results based on the weights I assign. Consider a search on a view fetching data from tables: Book, Author and Genre. Now, I want the searcher to be able to do: "Ludlum Fiction", "Robert Ludlum Bourne", "Bourne Ludlum", etc. Unfortunately, the only way I have been able to do that at present is this: http://pastebin.com/fdce11ff This is pretty bad, because I am manually breaking up the search string. I know I am doing this completely the wrong way, but can't figure out the right way to search across multiple fields in FTS. Can somebody help please?

• Why can't I shrink a transaction log file, even after backup?

  - by Jordan Hudson

  I have a database that has a 28gig transaction log file. Recovery mode is simple. I just took a full backup of the database, and then ran both: backup log dbmcms with truncate_only DBCC SHRINKFILE ('Wxlog0', TRUNCATEONLY) The name of the db is db_mcms and the name of the transaction log file is Wxlog0. Neither has helped. I'm not sure what to do next.

  I'm used to seeing temporary tables created with just the hash/number symbol, like this: CREATE TABLE #Test ( [Id] INT ) However, I've recently come across stored procedure code that specifies the schema name when creating temporary tables, for example: CREATE TABLE [dbo].[#Test] ( [Id] INT ) Is there any reason why you would want to do this? If you're only specifying the user's default schema, does it make any difference? Does this refer to the [dbo] schema in the local database or the tempdb database?

• Mono WCF NetTcp service takes only one client at a time

  - by vene

  While trying to build a client-server WCF application in Mono we ran into some issues. Reducing it to just a bare example we found that the service only accepts one client at a time. If another client attempts to connect, it hangs until the first one disconnects. Simply changing to BasicHttpBinding fixes it but we need NetTcpBinding for duplex communication. Also the problem does not appear if compiled under MS .NET. EDIT: I doubt (and hope not) that Mono doesn't support what I'm trying to do. Mono code usually throws NotImplementedExceptions in such cases as far as I noticed. I am using Mono v2.6.4 This is how the service is opened in our basic scenario: public static void Main (string[] args) { var binding = new NetTcpBinding (); binding.Security.Mode = SecurityMode.None; var address = new Uri ("net.tcp://localhost:8080"); var host = new ServiceHost (typeof(Hello)); host.AddServiceEndpoint (typeof(IHello), binding, address); ServiceThrottlingBehavior behavior = new ServiceThrottlingBehavior () { MaxConcurrentCalls = 100, MaxConcurrentSessions = 100, MaxConcurrentInstances = 100 }; host.Description.Behaviors.Add (behavior); host.Open (); Console.ReadLine (); host.Close (); } The client channel is obtained like this: var binding = new NetTcpBinding (); binding.Security.Mode = SecurityMode.None; var address = new EndpointAddress ("net.tcp://localhost:8080/"); var client = new ChannelFactory<IHello> (binding, address).CreateChannel (); As far as I know this is a Simplex connection, isn't it? The contract is simply: [ServiceContract] public interface IHello { [OperationContract] string Greet (string name); } Service implementation has no ServiceModel tags or attributes. I'll update with details as required.

• How can I search for numbers in a varchar column

  - by dave

  I've got a simple nvarchar(25) column in an SQL database table. Most of the time, this field should contain alphanumeric text. However, due to operator error, there are many instances where it contains only a number. Can I do a simple search in SQL to identify these cases? That is, determine which rows in the table contain only digits in this column. As an extension, could I also search for those column values which contain only digits and a space and/or slash. In other languages (eg. Perl, Java) a regular expression would resolve this quickly and easily. But I haven't been able to find the equivalent in SQL.

• MSSQL 2000 Stored Procedure to Split Shift Times

  - by JClaspill

  I am being asked to alter a system to include the ability to have pay differentials based on hours worked. The old method included a stored procedure (MSSQL2000 db) that did the basics, but simply knows the start and end of every shift. So, this is the information I start with: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 8.643055 | 2011-01-08 07:57:35.557 | 2011-01-08 16:36:10.120 And I need to turn that into something like: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 4.00 | 2011-01-08 08:00:00.000 | 2011-01-08 12:00:00.000 Dave | ShiftDiff1 | 4.50 | 2011-01-08 12:00:00.000 | 2011-01-08 16:30:00.000 The ShiftDiff's range from hours to certain days, to a combo of both. Should I try to make the SQL2000 SP do this or pass the info back to my ASP.NET(C#) app and let it handle it, then send back?
