There is something very strange going on here. Tested with ADO 2.7 and
MSDE/2000. At first, things look quite sensible.
You have a simple SQL query, let's say
select * from mytab where col1 = 1234
Now, let's write a simple VB program to do this query back to an
MSDE/2000 database on our local machine. Effectively, we'll

Hi All,
I'm a relative newbie to SQL Server, so please forgive me if this is a

Hello,
Running a query for the first time on DB2 takes a fixed amount of time.
But when query is executed for the second time, the amount of time is
usually less since the query is (most probably) cached already.
I would like to clear out the DB2-UDB 8.2 query cache (I want the
previous execution time again).
Any advice would be...

I had written an update query which was taking about 8 seconds to run
and considered it too slow. I copied the SQL statement from the query
and tried executing it from code which then ran in 1 second. To make
sure that I didn't miss anything,...

Hello,
I ran a query that I thought would take an hour, but instead took 14
hours to run. The consequence was it bogged down our data warehouse
and the overnight build was adversely impacted.
Is there a local setting I can set to limit the execution time my
query will take? I dont want to have a server setting and impact other

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
