Hi, Alain!
Somewhere between 1.11.5 and 1.11.9 we figured out a problem related to
mysql queries: if your database entry is NULL, we can't just simply set
a NULL value to an AVP, because that just deletes the previous value. So
you end up in a very inconsistent state. That's why we decided to set
the value "<null>" to all the fields that are NULL in the database (this
token is used in serveral other scenarios, that's why we picked this name).
Therefore, in order to properly test if a column is provisioned NULL in
the database is:
if ($avp(redirect) != "<null>") {
}
Let us know how this goes.
Best regards,

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.
