Hi All,
I have a table that currently contains approx. 8 million records.
I'm running a SELECT query against this table that in some
circumstances is either very quick (ie results returned in Query
Analyzer almost instantaneously), or very slow (ie 30 to 40 seconds to
return results), and I'm trying to work out how I improve performance....

I have an Access database with 58 fields in one table. I wrote many
of the field names so that they were descriptive so that others could
figure it out in the future. As an example, one field name is called
MissingPart14990aDescribe.
Should I be worried about the length of the field name? I'm expecting
about 20,000 records a year to be...

This UNION query is very slow. With only 3,000 records in the Parent table
and 7,000 records in the Child table, it takes about 60 seconds to run and
returns about 2200 records.
Access 97. All appropriate indexes and keys enforced.
Any ideas on speeding it up? Thanks.

My problem:
I'm having trouble with a query taking much too long to run; a query
without any criteria evaluating only 650 records takes over 300 seconds

The Setup:
I'm running Access 97 non-developer edition. I have exactly zero other
tools to use and no way to change that =(. ...

I have an append query that needs to run every time a line item is
added to a subform. The append writes to a table that is the source
for a pull down box. Problem is that it takes 5 seconds to run. This
makes adding lines to an order too slow for the users. The result of
the query provides real time availabilty, so I really do need this...

but then is less than one second for the next random number of openings
before slowing (6-7 seconds) again.
