Hi folks,
I do a considerable amount of queries based on a date, and or date range. I
have not had much luck with optimizing these queries. In some cases I use a
date field and others a datetime field.
The following query searches through 34,000 + records, while specifiying the
exact date
Keith,
The normal way to do a search for a range of dates would be
... WHERE a.submitdate BETWEEN '2003-07-01' AND '2003-07-14';
Is that what you're looking for?
submitdate happens to be a DATETIME field.
Your suggested query doesn't pull any results. Must I convert the field
first?
I'm not sure what errors are being reported to the server. I'm not sure how
to get those. I am not local to the box.
Is there a way to look at the log files without being at the box?
