BUG #: 57966 (SQLBUG_70)
SYMPTOMS
Running a query with two or more nested IN clauses and a CASE statement may cause the connection to be broken and the following error to be returned:
CAUSE
The query caused a handled exception in SQL Server, and the process was stopped.
WORKAROUND
To work around this problem, replace the IN clause with a SELECT COUNT(1) > 0 statement. For example, part of the query that looks like the following:
CASE WHEN T1.F1 IN (SELECT T2 FROM T2) THEN value1 ELSE value2 END
Can be rewritten as:
CASE WHEN (SELECT COUNT(1) FROM T2 WHERE T1.F1 = T2.F2) > 0 THEN value1 ELSE value2 END
STATUS
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
