Split function equivalent in T-SQL?

Question

I’m looking to split \'1,2,3,4,5,6,7,8,9,10,11,12,13,14,15...\' (comma delimited) into a table or table variable.

Does anyone have a function that returns each one

Answer 1

You've tagged this SQL Server 2008 but future visitors to this question (using SQL Server 2016+) will likely want to know about STRING_SPLIT.

With this new builtin function you can now just use

SELECT TRY_CAST(value AS INT)
FROM   STRING_SPLIT ('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15', ',') 

Some restrictions of this function and some promising results of performance testing are in this blog post by Aaron Bertrand.
