  • syntax for single row MERGE / upsert in SQL Server

    - by Jacob
    I'm trying to do a single row insert/update on a table but all the examples out there are for sets. Can anyone fix my syntax please: MERGE member_topic ON mt_member = 0 AND mt_topic = 110 WHEN MATCHED THEN UPDATE SET mt_notes = 'test' WHEN NOT MATCHED THEN INSERT (mt_member, mt_topic, mt_notes) VALUES (0, 110, 'test') Resolution per marc_s is to convert the single row to a subquery - which makes me think the MERGE command is not really intended for single row upserts. MERGE member_topic USING (SELECT 0 mt_member, 110 mt_topic) as source ON member_topic.mt_member = source.mt_member AND member_topic.mt_topic = source.mt_topic WHEN MATCHED THEN UPDATE SET mt_notes = 'test' WHEN NOT MATCHED THEN INSERT (mt_member, mt_topic, mt_notes) VALUES (0, 110, 'test');

  • Best way to randomly select rows *per* column in SQL Server

    - by LesterDove
    A search of SO yields many results describing how to select random rows of data from a database table. My requirement is a bit different, though, in that I'd like to select individual columns from across random rows in the most efficient/random/interesting way possible. To better illustrate: I have a large Customers table, and from that I'd like to generate a bunch of fictitious demo Customer records that aren't real people. I'm thinking of just querying randomly from the Customers table, and then randomly pairing FirstNames with LastNames, Address, City, State, etc. So if this is my real Customer data (simplified): FirstName LastName State ========================== Sally Simpson SD Will Warren WI Mike Malone MN Kelly Kline KS Then I'd generate several records that look like this: FirstName LastName State ========================== Sally Warren MN Kelly Malone SD Etc. My initial approach works, but it lacks the elegance that I'm hoping the final answer will provide. (I'm particularly unhappy with the repetitiveness of the subqueries, and the fact that this solution requires a known/fixed number of fields and therefore isn't reusable.) SELECT FirstName = (SELECT TOP 1 FirstName FROM Customer ORDER BY newid()), LastName= (SELECT TOP 1 LastNameFROM Customer ORDER BY newid()), State = (SELECT TOP 1 State FROM Customer ORDER BY newid()) Thanks!

  • What to do with syncobj in SQL Server

    - by hgulyan
    Hi. I run this script to search particular text in sys.columns and I get a lot of "dbo.syncobj_0x3934443438443332" this kind of result. SELECT c.name, s.name + '.' + o.name FROM sys.columns c INNER JOIN sys.objects o ON c.object_id=o.object_id INNER JOIN sys.schemas s ON o.schema_id=s.schema_id WHERE c.name LIKE '%text%' If I get it right, they are replication objects. Is it so? Can i just throw them away from my query just like o.name NOT LIKE '%syncobj%' or there's another way? Thank you.

  • How to estimate tomcat server requirements?

    - by Daniil
    We have a brand new webapp written that runs on Tomcat. So far, only one client is using it through the day. They run about 180 unique logins a day. Not really a lot IMO. Now, we managed to sell it to a brand new client who likes and wants to roll it out to 50,000 clients. How many of them will login at the same time - no idea. But I need to do the whole thing - allocate, create, config and maintain. OK - last is simple(errrr). The application runs off of Tomcat 5.5 on Gentoo (I'm thinking to upgrade to Tomcat 6) with MSSQL & mySQL behind. I do realize that a more enterprise ready application would be a better fit, but that's not an option at the moment. Since I've never done this before, I'm a bit lost. Can someone advice on how to go about estimating the equipment requirements for this client? Tomcat does have clustering, so that I can do. MS SQL - I'm sure they have something too. I'm thinking to stick it behind LVS (which we do use at the moment for something else too). Any help from people who deal with these details is greatly appreciated!

  • Tomcat 5.5 as service on Windows Server 2008 64bit

    - by netterdotter
    Hi, Has anybody managed to get Tomcat to run as a service on Win2008 64bit? I need it for a 3rd party component that my site relies on. It works fine otherwise, but I just can't get it to run as a service. I've tried all the googling I can, and experimented with various 64bit tomcat.exe / tomcatw.exe without success. Upgrading to Tomcat 6 didn't help either. I'm running Java 1.5 64bit.

  • Returning content directly from memcache - Django / HTTP Server

    - by RadiantHex
    Hi folks, I've built a web application with Django, I'm using Memcached in order to cache data. A few views cache the whole HttpResponse objects, therefore there might be a better alternative for returning the Memcached data other than going through Django. What could be faster alternatives for returning Memcached data on HTTP Requests ? I'm trying to make the operation as fast and lightweight as possible. Help would be much appreciated! :)

  • SQL Server 2008 FTS CONTAINSTABLE Not Returning More Than Five Rows

    - by Elijah Glover
    I have a single table called "Indexes", it contains one nvarchar and three ntext columns (all Full Text Indexes). Index is up to date. CONTAINSTABLE(Indexes, *), 'test', 5) //5 results No matter what I change the above keyword too, it only returns the first 3-5 results. It should roughly return 90-120 results, for the above query. SELECT count(*) FROM Indexes WHERE [Description] like '%test%' //122 results How would I start to troubleshoot this problem?

  • Compare date fields in SQL server

    Hi all, I've a flat file that I cleaned the data out using SSIS, the output looks like that : MEDICAL ADMIT PATIENT PATIENT DATE OF DX REC NO DATE NUMBER NAME DISCHARGE Code DRG # 123613 02/16/09 12413209 MORIBALDI ,GEMMA 02/19/09 428.20 988 130897 01/23/09 12407193 TINLEY ,PATRICIA 01/23/09 535.10 392 139367 02/27/09 36262509 THARPE ,GLORIA 03/05/09 562.10 392 141954 02/25/09 72779499 SHUMATE ,VALERIA 02/25/09 112.84 370 141954 03/07/09 36271732 SHUMATE ,VALERIA 03/10/09 493.92 203 145299 01/21/09 12406294 BAUGH ,MARIA 01/21/09 366.17 117 and the report (final results) attached in the screen shot from the final excel report. so what's happening is IF the same name or same account number is duplicate, that means the patient has entered the hospital again and needs to be included in the report. ![alt text][1] what I need to do is...

  • SQL Server catch error from extended stored procedure

    - by haxelit
    Hello I have an extended stored procedure that sends an error message. srv_sendmsg(pSrvProc, SRV_MSG_ERROR, errorNum, SRV_FATAL_SERVER, 1, NULL, 0, (DBUSMALLINT) __LINE__, buff, SRV_NULLTERM); I've set the severity to SVR_FATAL_SERVER just as a test to see if I can cause the message to throw an exception in the sql. In my SQL i'm doing: BEGIN TRY EXEC dbo.xp_somethingCool SET @Error = @@ERROR END TRY BEGIN CATCH PRINT 'AN Error occoured!' SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_MESSAGE() AS ErrorMessage; END CATCH I would think that when my xp sends the error message the tsql would catch the error and select the error_number and error_message. Instead what ends up happening is that the xp sends the message and the T-SQL continues on its way like nothing happened. The @@Error variable doesn't get set either. So I was wondering if there was any trick to getting SQL to catch an error from an XP ? Thanks, Raul

  • Will SQL Server Partitioning increase performance without changing filegroups

    - by Tom
    Scenario I have a 10 million row table. I partition it into 10 partitions, which results in 1 million rows per partition but I do not do anything else (like move the partitions to different file groups or spindles) Will I see a performance increase? Is this in effect like creating 10 smaller tables? If I have queries that perform key lookups or scans, will the performance increase as if they were operating against a much smaller table? I'm trying to understand how partitioning is different from just having a well indexed table, and where it can be used to improve performance. Would a better scenario be to move the old data (using partition switching) out of the primary table to a read only archive table? Is having a table with a 1 million row partition and a 9 million row partition analagous (performance wise) to moving the 9 million rows to another table and leaving only 1 million rows in the original table?

  • .net 4.5 Asp Mvc -> Error 403.14- IIS 7 - Windows Server 2008 R2

    - by Boas Enkler
    When I want to deploy an MVC 4 (.net 4.5) application to my iis i got the 403.14 calling me that the content ist not browseable. This also occurs when i deploy the unchanged mvc 4 template. when using the mvc 4 template with .net 4.0 everything works. I checked the other posts but can't figure out the solution. ist set i ran aspnet_regiss -i which completed without any errors. the only strange thing is that .net 4.5 is installed in the .net 4.0 directory %windows%/microsoft.net/Framework64/4.0.30319 From this folder i also ran aspnet_regiis. to ensure that 4.5 is installed i restarted the .net 4.5 setup and it tells me taht it is installes Also the apppools show me 4.0.30319 as version. There is an other application targeting mvc with 4.5 which runs. but i don't know wether it was created with a 4.0 templated and retargeted to 4.5 Any hints? The app.config is the unchanged default from the mvc 4 template. I just tested to create a subfolder which i convert to an application. placing the site there makes it working. But why not on root folder?

  • How to Use .NET Assembly from Legacy SQL Server 2000 DTS

    - by shyneman
    Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

  • Remove another user's lock obtained with sp_getapplock on SQL Server

    - by joshperry
    We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

  • Identity column SQL Server 2005 inserting same value twice

    - by DannykPowell
    I have a stored procedure that inserts into a table (where there is an identity column that is not the primary key- the PK is inserted initially using the date/time to generate a unique value). We then use SCOPEIDENTITY() to get the value inserted, then there is some logic to generate the primary key field value based on this value, which is then updated back to the table. In some situations the stored procedure is called simultaneously by more than one process, resulting in "Violation of PRIMARY KEY constraint..." errors. This would seem to indicate that the identity column is allowing the same number to be inserted for more than one record. First question- how is this possible? Second question- how to stop it...there's no error handling currently so I'm going to add some try/ catch logic- but would like to understand the problem fully to deal with properly

  • SQL Server 2008 automated database drop, create and fill

    - by lox
    For the database in my project I have a drop/create script for the database, a script for creating tables and SPs and an Access 2003 .mdb file with some exported values. To set up the database from scratch I can use my SQL management studio to first run one script, then the other and lastly manually run the sort of tedious import task. But I would like to do this as automated as possible. Hopefully something like putting the three files in a folder along with a fourth script to execute. Looking something like: run script "dropcreate.sql" run script "createtables.sql" import "values.mdb" How is this done? I hope to avoid using SSIS and the like. The tricky this is of course the import of data, where I can't seem to find a simple way. It is also important that the files a left as they are and not embedded into anything.

  • Addresses stored in SQL server have many small variations(errors)

    - by MAW74656
    I have a table in my database which stores packing slips and their information. I'm trying to query that table and get each unique address. I've come close, but I still have many near misses and I'm looking for a way to exclude these near duplicates from my select. Sample Data CompanyCode CompanyName Addr1 City State Zip 10033 UNITED DIE CUTTING & FINISHIN 3610 HAMILTON AVE CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE. CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVENUE CLEVELAND Ohio 44114 10033 UNITED DIECUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44144 10033 UNITED FINISHING 3610 HAMILTON AVE CLEVLAND Ohio 44114 10033 UNITED FINISHING & DIE CUTTING 3610 HAMILTON AVE CLEVELAND Ohio 44114 And all I want is 1 record. Is there some way I can get the "Average" record? Meaning, if most of the records say CLEVELAND instead of CLEVLAND, I want my 1 record to say CLEVELAND. Is there any way to par this data down to what I'm looking for? Desired Output CompanyCode CompanyName Addr1 City State Zip 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44114
