Hello,

 

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:

 

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;

 

+----------+--------------------+-----------------------+

| username | domain             | CAST(q_value AS CHAR) |

+----------+--------------------+-----------------------+

| 8500     | us.sip.globeop.com | 1.000                 |

| 3874     | us.sip.globeop.com | 1.000                 |

| 7050     | us.sip.globeop.com | 1.000                 |

| 2100     | us.sip.globeop.com | 1.000                 |

 

 

 

 

 

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?

 

Thanks,

 

Bob
