BUG: Convert of Local Variable of Type Float or Real

Last reviewed: April 28, 1997
Article ID: Q89825

The information in this article applies to:

Microsoft SQL Server version 4.2 for OS/2

BUG# OS/2: 1516 (4.2)

SYMPTOMS

If you use the convert function on a local variable of type float or real and the assigned value is NULL, the convert function will incorrectly convert the NULL value to a character string that is a "0".

For example:

   declare @f float
   select @f = NULL
   select @f, convert(char(20), @f)

   --------------- -----------------
              NULL 0

The following is what should have been returned:

   --------------- -----------------
              NULL NULL

This behavior occurs only with local variables of type float or real. If these are fields in a table, the convert functions correctly.

STATUS

Microsoft has confirmed this to be a problem in SQL Server version 4.2 for OS/2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
