Operating system: Linux
PHP version: 5.5.1
Package: PDO related
Bug Type: Bug
Bug description:'field=NULL' should be 'field IS NULL'
Description:
------------
When using PDO bindParam when it receives a NULL value the ultimate result
that
it sends to MySql is field=NULL instead of field IS NULL.
Test script:
---------------
$editStmt = $db->prepare("UPDATE employee SET
startDate=:startDate,department=:department,jobTitle=:jobTitle WHERE
name=:emplName AND startDate=:oldStartDate AND department=:oldDepartment
AND jobTitle=:oldJobTitle LIMIT 1");
$editStmt->bindParam('startDate',$startDate);
$editStmt->bindParam('department',$department);
$editStmt->bindParam('jobTitle',$jobTitle);
$editStmt->bindParam('emplName',$emplName);
$editStmt->bindParam('oldStartDate',$oldStartDate);
$editStmt->bindParam('oldDepartment',$oldDepartment);
$editStmt->bindParam('oldJobTitle',$oldJobTitle);
// catchException($editStmt,$db);
$editStmt->execute();
$editResult = $editStmt->fetchAll(PDO::FETCH_ASSOC);
/* If any one of these variables happens to be NULL then the whole
statement fails because it will output, for example, 'AND department=NULL'
instead of 'AND department IS NULL' */
Expected result:
----------------
MySql will not except field=NULL properly it should be field IS NULL
Actual result:
--------------
I can do this in MySql however when using PDO I have to create an entirely
different statement myself for the exceptions of NULL values which becomes
very
tedious a problem I never had using the depreciated mysql functions or when
using
mysqli.
