I kept getting the error “Procedure expects parameter ‘@statement’ of type ‘ntext/nchar/nvarchar’”. Being true to my name (“FailBoy”) I knew I was doing something stupid. In my SQL Script I had declared something like this:

DECLARE @tSql VARCHAR(max)
SET @tSql = ‘<insert Dynamic query here>’
execute sp_executesql @tSql

Can you spot the problem? The problem is the declaration of the variable as VARCHAR. The execute sp_executesql procedure expects a NVARCHAR value. I simply replaced the VARCHAR with NVARCHAR and all worked perfectly.
