Here's a really weird one for any SQL Server gurus out there...
We have observed (SQL Server 2000) scenarios where a stored procedure
which
(a) begins a transaction
(b) inserts some rows into a table
(c) re-queries another table using a subquery which references the
inserted table (correlated or not)

Postgresql 7.4b2 (approximately, compiled out of CVS)
When I have a subquery that has a complex subquery as one of the result
columns, and then that result column is used multiple times in the parent
query, the subquery is inlined for each one. This means multiple redundant
executions of the subquery.
I recall there was a way to defeat...

Hi!
Does anyone here know of a way to goad DB2 into converting a correlated
subquery to a non-correlated one? Does DB2 ever do such a conversion?
We have a query of the form
SELECT .. FROM A
WHERE EXISTS (SELECT 'X' FROM B, C
WHERE B.COL1 = A.COL1
AND B.COL2 = A.COL2

This approach I found very efficient and FAST when compared to the
rowcount, or Subquery Approaches.
This is before the advent of a ranking function from DB such as
ROW_NUMBER() in SQL Server 2005 and the likes of it. So
This one works with SQL2000
What do you think?

Hello!
Here is the statement in question:
--STATEMENT A
SELECT * FROM dbo.myTable WHERE colX in (SELECT colX FROM
dbo.sourceTable)
The problem with Statement A is that 'colX' does not exist in
'dbo.sourceTable'. It does, however, certainly exist in 'dbo.myTable'.
Breaking the statement down, we have:

Hi all--
Does anyone have any insight as to how I might create a search form
that allows a user to select criteria based on any related table in
the whole database. The search form I have now only allows me to
filter based on variables in a single table. I would like to have a
search form where I can select multiple variables (from various...
