 EXEC @sql 

}

I cannot understand what exactly the problem is? Do we have some limits of characters while executing Dynamic Sql like I am doing. I tried printing what I am getting in @Sql, I can get the results what I am looking for. But when I go like this using EXEC @Sql it gives me the error.

Any suggestions?

Answer 1

Try
Declaring @sql as nvarchar(max)
then

exec sp_executesql @sql

instead of

exec @sql

Executing dynamic sql with just exec is very limited. See this link http://www.sommarskog.se/dynamic_sql.html.
