[asterisk-users] astdb delete all keys with the value of x

To do it without using an external database, you could create a shell
script to do it that you would execute with a system call.  You could get a
list of everything with:

asterisk -rx "database show"

>From there, you could grep the results for the value you are looking for,
use awk or even cut to get the family and key names, then for each match,

asterisk -rx "database del <family> <key>"

It's a dirty way of doing it, but it would work.  When I used the Asterisk
DB for something, I was able to change my dialplan around to make things
unique for each call so I could run a "DBDeltree" after the call was
complete.  That being said, you definitely get a lot more control with an
external database and it's easy to make the calls within your dialplan.  It
really depends on how big of a system you're setting up and how often you
would need to run these commands to determine if it's worth the added
trouble of installing / configuring / maintaining something like MySQL.
For me, I've used MySQL very heavily in the past, and only recently have I
created something that uses the Asterisk database (after using Asterisk for
6 years).  Even then it was more of a challenge to myself to see if I could
make it work, but for what I'm doing it really is probably the best option
(especially since it's on a pre-existing Asterisk install that was not
configured with ODBC support).
