#31238 [Ana]: pg_field_is_null fails for column with upper case name

ID: 31238 Updated by: iliaa@php.net Reported By: phpdevel-no-spam at pv2c dot sk Status: Analyzed -Bug Type: PostgreSQL related +Bug Type: Documentation problem Operating System: * PHP Version: 4CVS, 5CVS (2004-12-22) Assigned To: sniper New Comment: This should be documented. Previous Comments: ------------------------------------------------------------------------ [2004-12-22 09:06:10] sniper@php.net I can verify this. It happens because the underlying PQfnumber() function tolower()'s the passed field name. You can avoid that by passing the name double-quoted: - if(pg_field_is_null($res, 0, $field)) + if(pg_field_is_null($res, 0, "\"$field\"")) I have prepared a patch for this but it's up to the "committee" whether we will fix this in sources or in documentation. ------------------------------------------------------------------------ [2004-12-22 01:00:11] phpdevel-no-spam at pv2c dot sk Description: ------------ When calling pg_field_is_null() with 3. parameter the column name and it has upper case letters in it, an error is the result: "PHP Warning: pg_field_is_null(): Bad column offset specified in bugtest.php on line 15" This bug was reproduced using PostgreSQL 7.4.6, PHP 4.3.10 PostgreSQL 7.4.6, PHP 4.3.9 PostgreSQL 7.4.6, PHP 4.3.10 using two different servers. This bug doesn't occur when the 3. parameter is column offset, or the column name contains only lover case letters. Reproduce code: --------------- http://www.pv2c.sk/php/bugtest.zip (1KB) Included is also a sample db creation script. Expected result: ---------------- Just want to know if the column is NULL. Actual result: -------------- Just an warning. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31238&edit=1
