Hi Alain,
yes, it was a fix in avp_db_query() - if you query for multiple columns
in a row, and if one of these columns returns NULL, it will not be
reported as empty AVP , but as an AVP holding "<null>" value :
https://github.com/OpenSIPS/opensips/commit/e1257269bcc30df56dd9b6bc90a243c5839d5922
Is was a must to properly handle multi row results with multiple columns.

Hi All,
I’m trying to migrate form 1.11.5 to 1.11.9 and i have a problem to
test the value of a mysql query when the reseult is null.
In 1.11.5 this test « if (!$avp(redirect) == NULL) » works, but
doesn’t work in 1.11.9.
Is there a change in code ?
What is the corect way to test a null value from avp ?
Regards
Alain.
