BUG: Nested STUFF() Functions Return NULL
The information in this article applies to:
- Microsoft SQL Server version 4.2x
BUG# NT: 319 (4.2)
When you attempt to change several characters in a character string using nested calls to the STUFF() Transact-SQL function, NULL is returned instead of the expected character string.
The result of nested STUFF() functions is NULL.
A local variable can be used to eliminate the need for nesting calls to STUFF(). For example, to change the slash marks in a date to hyphens, the following Transact-SQL statements could be used:
declare @tempvar char(8) select @var = stuff( "01/01/93",6,1,"-" ) select @var = stuff( @var, 3,1,"-" ) select @var
Microsoft has confirmed this to be a problem in SQL Server SQL Server version 4.2.
