Description: ------------ When combining joinAdd and whereAdd conditions the whereAdd conditions on the seperate objects are combined implicitly with AND in the generated SQL. For example $country->whereAdd('name = \'Germany\''); $person->joinAdd($country); $institution->whereAdd('name = \'test\''); $person->joinAdd($institution); $person->fetch(); Combines the condition on $country and $institution with 'AND' so that it would fetch people where their names are 'test' AND they are in a country with the name 'Germany' Reproduce code: --------------- The following diff adds an optional joinAdd logic parameter which is passed through to the subsequent whereAdd calls. This allows one to carry out the join add mentioned above returning records with 'Germany' as the name in the country table OR 'test' as the name of the institution. 18c18 < * @version CVS: $Id: DataObject.php,v patch 2005/05/09 16:02:00 graceej Exp $ --- > * @version CVS: $Id: DataObject.php,v 1.353 2005/04/20 07:50:01 alan_k Exp $ 2822,2824d2821 < * @param optional $joinLogic string The whereAdd logic to use when adding whereAdd conditions < * to nested joins default is 'OR' (default is 'AND') < * 2829c2826 < function joinAdd($obj = false, $joinType='INNER', $joinAs=false, $joinCol=false, $joinLogic='AND') --- > function joinAdd($obj = false, $joinType='INNER', $joinAs=false, $joinCol=false) 2836d2832 < 3016c3012 < $this->whereAdd("{$joinAs}.{$ofield}={$table}.{$tfield}",$joinLogic); --- > $this->whereAdd("{$joinAs}.{$ofield}={$table}.{$tfield}"); 3055c3051 < )),$joinLogic); --- > ))); 3059c3055 < $this->whereAdd("{$joinAs}.{$kSql} = {$obj->$k}",$joinLogic); --- > $this->whereAdd("{$joinAs}.{$kSql} = {$obj->$k}"); 3063c3059 < $this->whereAdd("{$joinAs}.{$kSql} = 0",$joinLogic); --- > $this->whereAdd("{$joinAs}.{$kSql} = 0"); 3078c3074 < $this->whereAdd("($cond)",$joinLogic); --- > $this->whereAdd("($cond)");

This really needs adding to a DB_DataObject_Join Class, - as the join code is far to complex at present.. For the time being It's best do more complex joins like this using function myjoin() { $this->_join .= '......' } or similar..
