I’m using dynamic SQL and I need to exec a long SQL query, First

  • 0

I’m using dynamic SQL and I need to exec a long SQL query, First I declare @var with query as nvarchar(4000), but my query is longer than 4000 chars.
I try to change to nvarchar(8000) but raise an Exception that can’t be longer than 4000 chars.

Finally I declare var as varchar(8000) and no error ocurrs , but when I going to exe sp_executeSQL
raise and error that sp_executeSQL expect a ntext/nchar/nvarchar.

How I can exec a longer Sql Query with sp_executeSQL ?
Thnks!

I’m using Sql Server Express 2005.

    As you are on 2005 you can use declare @var nvarchar(max) for up to 1 billion characters.

    You will find using PRINT statements doesn’t work to view the variable contents for very long strings so you can do 

    SELECT @var AS [processing-instruction(x)] FOR XML PATH('')

    To see the untruncated contents.
