Review request for Asterisk Developers.


Changes
-------

Changed the patch to be for a trunk version. paramcount++ fixed. Changed to set NULL value for non-text columns,
not only integer ones.


Bugs: ASTERISK-23459
    https://issues.asterisk.org/jira/browse/ASTERISK-23459


Repository: Asterisk


Description
-------

This patch fixes setting nullable integer columns to NULL instead of an empty string, which fails for PostgreSQL, for example.
The current code is supposed to do so, but the check is broken. The patch also allows the first column in the list to be a nullable integer.
Also, the check for existence of a mandatory column checked for the first column in the list instead of the key field lookup column.


Diffs (updated)
-----

Diff: https://reviewboard.asterisk.org/r/3335/diff/


Testing
-------

Tested by me. Use case scenario: Asterisk + res_odbc + PostgreSQL backend, SIP realtime peers + regs.
When a 'port' column in SIP regs (I assume this also applies when using sippeers only) is a nullable integer,
Asterisk tries to write an empty string here during SIP endpoint deregistration.


Thanks,
