    <p>i am useing the query below, when i run this query once per page there is no problem, but it needs to be called around 30+ times with slightly different values on a single page, sometimes it runs ok, sometimes the page never loads, and sometimes i get a "server has gone away" error, <a href="http://dev.mysql.com/doc/refman/5.0/en/gone-away.html" rel="nofollow">http://dev.mysql.com/doc/refman/5.0/en/gone-away.html</a></p> <p>is this a performance problem, do i need to break down this query into smaller ones (will that even have any effect), or is there something else i can do ?</p> <pre><code>SELECT normalmtm.id, normalmtm.amt, normalmtm.lockexpire, ptassumptions.id, ptassumptions.zero, ptassumptions.beta, ptdata.id, ptdata.date FROM normalmtm INNER JOIN ptdata ON ptdata.date = normalmtm.lockdate INNER JOIN program ON program.clientcode = '1' AND program.clientprogram = normalmtm.program AND program.normalprogram = 'program' INNER JOIN ptassumptions ON ptassumptions.clientcode = '1' AND ptassumptions.program = program.normalprogram INNER JOIN purpose ON purpose.clientcode = '1' AND purpose.clientpurpose = normalmtm.purpose AND purpose.normalpurpose = ptassumptions.purpose INNER JOIN status ON status.clientcode = '1' AND status.clientstatus = normalmtm.stage AND status.normalstatus = ptassumptions.status WHERE normalmtm.clientcode = '1' GROUP BY normalmtm.id </code></pre> <p>the normalmtm table has a few thousand rows, and the other tables are smaller normalised tables with around 100 rows</p> <p>EDIT</p> <p>its a WAMP server running on a local windows machine, Apache Version :2.2.11, PHP Version :5.3.0, MySQL Version :5.1.36</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
