Gets any special processing requirements for the condition operator.

Some condition types require special processing, such as IN, because the value data they pass in is not a simple value. This is a simple overridable lookup function. Database connections should define only those operators they wish to be handled differently than the default.

Parameters

$operator: The condition operator, such as "IN", "BETWEEN", etc. Case-sensitive.

Return value

The extra handling directives for the specified operator, or NULL.

Code

public function mapConditionOperator($operator) {
    static $specials;
    // Function calls not allowed in static declarations, thus this method.
    if (!isset($specials)) {
        $specials = array(
            // In PostgreSQL, 'LIKE' is case-sensitive. For case-insensitive LIKE
            // statements, we need to use ILIKE instead.
'LIKE' => array(
                'operator' => 'ILIKE',
            ),
            'NOT LIKE' => array(
                'operator' => 'NOT ILIKE',
            ),
        );
    }
    return isset($specials[$operator]) ? $specials[$operator] : NULL;
}
