SYMPTOMS

Using the SQL Server ODBC driver, output from the PRINT statement to the Results window inside the IDE stops after 64 lines.

CAUSE

The output of the PRINT statement from the server is put in a queue by the ODBC driver. The queue can hold up to 64 entries.

Because all of these PRINT statements occur within a single SQLExecute call, the queue is being filled and the PRINT output is truncated.

STATUS

Microsoft has confirmed this to be a problem in Visual C++ Enterprise Edition, version 4.2. This problem was corrected in Visual C++ Enterprise Edition, version 5.0.

MORE INFORMATION

For example, if you execute the following stored procedure with a value above 64, it will stop printing after the contents of @i equal to 64:

  create procedure JustLoop (@num integer) as

       declare @i integer
       declare @s varchar(255)

       select @s = convert(varchar, @num)

       select @i = 1
       while (@i <= @num)
       begin
           select @s = convert(varchar, @i)
           print @s
           select @i = @i + 1
       end

   return
