Question

I have an stupid question about output.
I have an stored procedure that inside is doing a dynamic SQL for checking if there are records in a table, this is the example:

SET @sqlLog = 
    'SELECT 1 FROM MyTable 
      WHERE TableName = ''' + @TableName + '''' + '
        AND TheKey = ''' + convert(varchar(50), @LoadGuid) + ''''                                    
EXEC(@sqlLog)

After that I’m using @@RowCount to validate if the result is 0 or not.

The problem is that is inside a WHILE and for each row is showing the result in the output window of SQL Management Studio and I don’t really want this.
Any idea? Thank you!

Why do you even need dynamic SQL for this?, you could do something like the following:

IF EXISTS ( SELECT 1 FROM MyTable 
            WHERE TableName = @TableName 
            AND TheKey = convert(varchar(50), @LoadGuid))
BEGIN
    -- Your logic here
END
