Hi

I try to use a delimeted string in a Query like this....



DECLARE @Books nVarChar(500)
SET @Books = 'Book1,Book2'

....

WHERE        (dbo.Books.BookName IN (@Books)) AND (dbo.Books.Language = 'se') AND (dbo.Books_1.Language = 'gb')

Its not working, it only works with one book name... what could be wrong?

For some reason WHERE ';'+@Books+';' LIKE '%;'+CAST(dbo.Books.BookID AS VARCHAR(32))+';%' works, I gonna have to use that instead..

it does pattern matching and tries to match ; + BookID + ; within the passed parameter list which is exactly what you want
Only thing is for large data performance might be an issue
so you may need to use a parsing udf and parse values out from delimited parameter list and add a join to it from your table
