Question

At my work I have several tables with over 200,000 rows of data. I have to set-up some queries that look over 15,000+ at a time so sometimes I get this error:

PHP Fatal error: Maximum execution
time of 180 seconds exceeded

So, how do I speed up faster queries?

The query is like this:

SELECT  toemail, toname
FROM    email_sent
WHERE   companyid = '$member[companyid]'

Thanks.

Answer 1

Create an index on email_sent (company_id):

CREATE INDEX ix_emailsent_companyid ON email_sent (company_id)
