Question

I’m having an issue with this procedure.
Here’s the code

declare @sql nvarchar(4000)
set @sql =  N'SELECT @resp2 = count(*) from '+ @NameTable + ' where datum = ''1'' or datum = ''2''    '
    EXEC sp_executesql
    @query = @sql,
    @params = N'@resp2 INT OUTPUT', 
    @resp2 = @resp2 OUTPUT 

“Procedure expects parameter ‘@statement’ of type
‘ntext/nchar/nvarchar’.”

Am I not giving the statement? (@sql)

All I want to do is set a value to @resp2 in the execution.

Answer 1

According to the manual, you should provide a value for the parameter called @statement, but you are supplying it as @query.

So it should be:

declare @sql nvarchar(4000)
set @sql =  N'SELECT @resp2 = count(*) from '+ @NameTable + ' where datum = ''1'' or datum = ''2''    '
EXEC sp_executesql
@statement = @sql,
@params = N'@resp2 INT OUTPUT', 
@resp2 = @resp2 OUTPUT 

Just follow the manual, and you’ll be okay.
