- Microsoft Visual C++, version 4.2

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
