Query and ?sub query??
Hi there,I hope this is the right place to ask this question.I have two Access tables (tblUsers and tblMessages) to use in datagrid. tblMessages has two relations with tblUsers - the UserID field and the SenderID field, both of which are one-to-many relationship. When the user goes to the inbox, the data selected needs to do the following:1) pull out the messages with the UserID that matches the current user id number.2) since it needs to display the username of the person who sent the message, I need to pull out 'username' from tblUsers where it matches the SenderID.

purposes. If anyone has any suggestions they would be more than appreciated.
Thanks in advance,

There is a generic answer to your question: Yes, there is a construct
called a sub-query that allows you, in 1 SQL statement, to query from a

I'm working on converting an Access DB that I created into an ASP.NET application (and attempting to learn ASP at the same time...). One of my queries was very complex and required running a different query first, and then working off of that one. Any suggestions on the best way to do this in ASP?

is it more efficient to make multiple parameters or to use sub queries, for instance

would it be best to do a subquery to get the results of the people who have not been called, then off of that sub query run the main query of which state i would like to call?

We have a sql query that is causing a few issues in terms of
performance as the optimisor is choosing to table scan where
an index will certainly yield significant gains. As proven
when snapshotting the query and adding an index hint
Unfortunatley since the query is dynamically created by a
3rd party application, we are unable to influence this with
index hints and are dependant on the optimiser.
The table that is table scanning is partitioned (has also
hust been repartitioned to address a slight inbalance across
partitions) and has 7.6M records. It has been recently

I want to add items to the pencil menu in the Host SQL page. Eg. "Save SQL Query".
Could someone point me in the right direction on how to populate the pencil menus. Thanks in advance.
