SYMPTOMS

A batch containing a declare cursor that contains certain correlated subqueries will be ignored. No error messages are generated, but none of the commands in the batch are executed.


STATUS

Microsoft has confirmed this to be a problem in the Microsoft SQL Server version 6.00. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

The type of query that encounters the error is: 


DECLARE fred scroll CURSOR for
select ( select max(t2.type) from titles t2 where t2.pub_id <> 1.pub_id)
from titles t1
go

This can be recoded: 

DECLARE fred scroll CURSOR for
select max(t2.type) from titles t1 , titles t2

group by t1.title_id
go
