combining results of two select objects Zend\Db\sql\sql
问题 I know the way to combine two select statments would look like this: SELECT tableA.Id FROM tableB INNER JOIN tableA ON [tableB].Id = tableA.Owner UNION SELECT tableA.Id, tableA.Name FROM [tableC] RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id But how would it be if I'm using sql object? $sql = new Sql($adapter); $select = $sql->select(); $select ->from(tableA); $select ->join(...) Any help would be much appreciated. Thanks in advance 回答1: ZF2 does have combine that works as union -
