Hi list,
Perhaps this fits better into a bug report, but I'd like to know if somebody
out there experienced a similar issue.
I am executing a "select count" query using the avp_db_query function, but it
is not storing the results in any avp. Other queries are working fine.
I use db_mysql connected with a mysql 5.1 server.
I have tested this with kamailio-3.1.0 and kamailio-3.1.3, both didn't work. In
an old box (version 1.3.x), the same query was returning the correct value.
---------------------------------------------------
Here is the case which is not working:
Code:
avp_delete("$avp(s:count)");
$var(ret) = avp_db_query("SELECT count(*) FROM subscriber where username='foo'",
"$avp(s:count)");
xlog("L_INFO", "var(ret)=$var(ret) avp(s:count)=$avp(s:count)");
Output:
INFO:<script>: var(ret)=1 avp(s:count)=<null>
(notice the return code 1, which means that the query was successfull and there
should be some output value stored in the avp, but it is<null>)
---------------------------------------------------
And here is one case which works as expected:
$var(ret) = avp_db_query("SELECT id FROM subscriber where username='foo'",
"$avp(s:count)");
Output:
INFO:<script>: var(ret)=1 avp(s:count)=11
---------------------------------------------------
Thanks in advance for any feedback.
It might be related to the type of the value returned by mysql library
for 'count(*)' - the avps support only integer or string values.
Have you tried also with sql_query(), is it giving the same result?
Cheers,
Daniel
