How to convert comma delimited string to table or array in sql server 2008 without using dbo.split function because the system doesn’t support this function? Eg of string: ’12,14,15’ Change this to *Table column* 12 14 15 Or array=[12,14,15] I would like to insert comma separated string values into a table ultimately.

I've created a View from a table in another database. I have dbo rights to the databases so viewing and updating is not a problem. This particular View did not have an "id" column. So I added one to the View by using ROW_NUMBER. Now I had a problem with a table, in the same database, not showing up in LightSwitch but that was solved by changing the id column to be NOT NULL.

What is the best way to loop over a database table's rows in SQL Server 2008 R2? I am looking for something which is fairly similar to writing foreach ( ) and quite performant. Thanks BradC Best performing: don't loop over a table's rows. Use set-based operations. Here's a good discussion of WHY Perhaps you want a CURSOR? See SQL Server Cursor Examples (also provides links and discusses issues/alternatives/reasons). It may or may not meet the definition of 'best' -- SQL DQL really does like to work with 'set operations' (and this is what it's designed to do, there are some caveats with using
