<DIV><div class=WordSection1><p class=MsoNormal>Hello, <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m interested in using the htable and/or mtree modules to keep my aliases and did lookups in memory to minimize the amount of SQL lookups that are being performed. It’s easy enough to use htable to cache a single value after it is retrieved but what I’m not clear on is how I can do it when SQL returns multiple destinations. Consider the following query and returned results:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>SELECT username,domain,CAST(q_value AS CHAR) FROM aliases where alias_username = '10001' AND alias_domain = 'us.sip.globeop.com' AND active = '1' ORDER by q_value;<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>+----------+--------------------+-----------------------+<o:p></o:p></p><p class=MsoNormal>| username | domain | CAST(q_value AS CHAR) |<o:p></o:p></p><p class=MsoNormal>+----------+--------------------+-----------------------+<o:p></o:p></p><p class=MsoNormal>| 8500 | us.sip.globeop.com | 1.000 |<o:p></o:p></p><p class=MsoNormal>| 3874 | us.sip.globeop.com | 1.000 |<o:p></o:p></p><p class=MsoNormal>| 7050 | us.sip.globeop.com | 1.000 |<o:p></o:p></p><p class=MsoNormal>| 2100 | us.sip.globeop.com | 1.000 |<o:p></o:p></p><table border=1 cellpadding=0 cellspacing=0 class=MsoNormalTable style='margin-left:8.4pt;border-collapse:collapse;border:none'><tr><td style='width:43.5pt;border:solid windowtext 1.0pt;padding:0in 5.4pt 0in 5.4pt' valign=top width=58><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></td><td style='width:81.0pt;border:solid windowtext 1.0pt;border-left:none;padding:0in 5.4pt 0in 5.4pt' valign=top width=108><p class=MsoNormal><o:p> </o:p></p></td><td style='width:92.25pt;border:solid windowtext 1.0pt;border-left:none;padding:0in 5.4pt 0in 5.4pt' valign=top width=123><p class=MsoNormal><o:p> </o:p></p></td></tr></table><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In my existing script I just append the results as branches and all works well but I end up with a lot of unnecessary SQL traffic. I see the htable supports array but I’m not sure how to go about assigning multiple values to a single key to use later. How can I take the above results and store them in memory for use by other transactions? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Bob<o:p></o:p></p></div></DIV>
