SYMPTOMS
When you run a query that contains a CASE statement in
Microsoft SQL Server 7.0, the
SET
ANSI_PADDING ON option may not work as expected. This problem occurs when the
following conditions are true:
- The CASE statement contains multiple literal character
strings.
- The literal character strings have different
lengths.
- The literal character strings have trailing
spaces.
For example, in the following Transact-SQL script, the SELECT
statement returns 'test1result'. The SELECT statement should return 'test1
result'.
DBCC FREEPROCCACHE
GO
SET ANSI_PADDING ON
GO
DECLARE @x integer
SET @x = 1
SELECT CASE WHEN @x = 1 THEN 'test1 ' WHEN @x = 2 THEN 'test2 ' ELSE 'test 3 ' END + 'result'
