join problem

[eluser]Josepzin[/eluser]
I think i have the some problem...

Code:

$this->db->join('catalogs_arranges', 'catalogs_arranges.key=nexts AND catalogs_arranges.catalog_id=catalogs.id', 'LEFT');

create this:

Code:

LEFT JOIN `catalogs_arranges` ON `catalogs_arranges`.`key`=`nexts` AND catalogs_arranges.catalog_id=catalogs.id

The "nexts" string is "protected" by CI... What is the solution??
