Click here for the latest Delimited Split Function.

Then, it's just:

SELECT ITEM

FROM dbo.DelimitedSplit8k(@val, ',')

Would you care to do a performance test of this code against the function that I linked to? Let's make it a nice test... say 1 million rows of data. Stuff to be split out can be any length < 8000 characters. Commas should not be in the same position in the rows... they need to be random.

I predict that the function will blow the socks off of this code. Heck, I'd predict that while this code is running, I might have enough time to go get and consume a drink.

Nice resource, Wayne.

Thanks. I've been using it so much lately, that I've made it into a snippet.

Thanks guys but what if I have two variables

Just call the DelimitedSplit8K function for each one.

However, I sense that there is something else going on. Do you need to link these variables together? Can you give us the complete story on this?
