andCondition - Error parsing condition

I got an error condition with the following andCondition:

        $c->andCondition(array("( `dvdProducts`.`studio` REGEXP 'Warner Bros' )");

And it’s ok with:

        $c->andCondition(array("( `dvdProducts`.`studio` = 'Warner Bros' )");

Is there any reason for this ?

Under PhpStorm I reach the following code block:

    public function isConditionalClause($string) {
        $matched= false;
        if (is_string($string)) {
            foreach ($this->_operators as $operator) {
                if (strpos(strtoupper($string), $operator) !== false) {
                    $matched= true;
                    break;
                }
            }
        }
        return $matched;
    }

REGEXP doesn’t appear in the allowed list of operators inside the isConditionalClause function

I think there may be a bug filed for this in the xpdo project; can you do a quick search and if not add a ticket at http://bugs.modx.com/projects/xpdo/issues? In the meantime, you should be able to do the following, which is much better from a query abstraction perspective anyway:

<?php
$c->where(array('dvdProducts.studio:REGEXP' => 'Warner Bros'));

Ok, I will do my best.

is there anywhere an exhaustive list of examples on how should be set up these conditions ? I read this page. If it is obvious for most of them (=, >, <, ...), how are implemented :

BETWEEN : like this ? $c->where(array(’name:BETWEEN’ => ’vmin,vmax’));
NOT IN : $c->where(array(’name:NOT IN’ => ’v1,v2,v3,...,vn’));

COALESCE ? $c->where(array(’name:COALESCE’ => ’v1,v2,v3,...,vn’));

INTERVAL ?
LEAST ? GREATEST ?

Are the name of operator case sensitive ?
Thanks.

Though xPDO has support for IN and NOT IN operators when binding values like this, it does not currently handle BETWEEN, nor does it support COALESCE() or other SQL-standard or engine-specific functions. When writing these types of conditions, just write them as a string for now, i.e.

<?php
$c->where(array(
    "{$modx->escape('name')} BETWEEN {$x} AND {$y}",
));

Thanks for the information.
Regarding, REGEXP, this request has been logged as a feature (I just looked for bugs).
As mike, I think that this operator will be a great value.
