Hi, I'm using ZF 1.7.3 and first time tried to union with ZF. In phpDoc section it says; /* The first parameter $select can be a string, an existing Zend_Db_Select object or an array of either of these types. */
And what it does on the first a few lines of function is; if (!is_array($select)) { $select = array(); } Even i pass the zend_db_select object in an array, it produces sql query in a logic like; SELECT t1.fields* *SELECT t2.fields* * FROM t2 WHERE t2.conditions FROM t1 WHERE t2.conditions I'm using mysqli connection type with version 5.1.11
