T-SQL: issue with string concat

Answer 1

You can't parametrise or concatenate the parameters of OPENROWSET. It is constant values only.

You'll have to use dynamic SQL and a temp table, or consider using SSIS for example

Answer 2

This article pointed me in the right direction when I had the same issue with OPENQUERY:

Basically, you can wrap the entire statement in a variable (nvarchar), including the openrowset, and run exec sp_executesql @sql. It gets a little ugly to read around the 's though, because you'll have to escape them with ''.
