Now you're off and running turning lists to comma lists, in corporate that with the list table function I posted sometime back, and you can go backwards and forwards!

Service Broker and External Activator for Sql Server...

-
I ntroduced in Sql Server 2005, Microsoft's Service Broker is a Messaging Queue for Sql Server.  You can audit tables, trigger events, and even call web services (Using the External Activator). Follow this excellent tutorial by Dev Kimchi which helps you step by step and clearly explain how to setup your Service Broker messaging queue. To get started with the external activator you will require the version for the version of Sql Server you are running, click on any of the Microsoft download links and follow the install instructions: Microsoft® SQL Server® 2012 Feature Pack Microsoft® SQL Server® 2014 Feature Pack One last thing before you get frustrated installing the External Activator service on a remote server.  At least for the 2012 version, it still required .Net 3.5 installed on the destination computer/server.  If you are trying to install on a Windows 2012 server follow this helpful guide on how to get .Net 3.5 installed now that the latest packs have been releas

If you are familiar with TSQL and want to get a row count from your tables you might be tempted to run a simple Select count(*) from myTable This however can be a lengthy wait if you have millions and millions of records.

Instead consider selecting your rowcounts from your system tables SELECT OBJECT_NAME(id), ROWS, indid FROM sysindexes WHERE indid < 2 AND OBJECT_NAME(id) IN ('myTableName') Looking forward beyond Sql Server 2005 and beyond the following select should be used and will provide you with the needed information as system tables access may be depracated SELECT DISTINCT OBJECT_NAME(P.object_id) AS [Name], ROWS FROM sys.indexes I INNER JOIN sys.partitions P ON P.object_id = I.object_id AND P.index_id = I.index_id WHERE I.index_id < 2 AND OBJECT_NAME(P.object_id) IN ('myTableName') So why am I searching for index smaller than 2? In short from the article below you'll find that pure data p

List to Table

-
E very now and again, a developer will be faced with the task of referincing a List of id's. It's typically irresistable to want to push all these IDs into a single field. If you're searching then you may end up considering a cursor... for that I decided to write the following function... it's like other Tsql functions that push a list to a table, but this is my take on it... I release the code here with out warranty. CREATE FUNCTION udfListToTable (@HList VarChar(2000), @Delimiter CHAR(1)) RETURNS @ListTable TABLE (Field1 VARCHAR(6)) AS BEGIN --By: Francisco Tapia --Date: 2/1/2005 --Purpose: To convert a Comma delimited text to a Temp Variable table To help avoid dynamic sql -- Instead you can join the temp table or use it in your where clause if a field is IN the subquery DECLARE @FieldText as VarChar(6) IF RIGHT(RTRIM(@HLIST),1) <>@Delimiter SET @HList = @HList + @Delimiter WHILE CHARINDEX(@Delimiter, @HList) > 0 BEGIN
