Zend DB Select 具有多个表联接

尝试使用复制以下查询Zend_Db_Select。有什么指点吗？

SELECT 
  compounds.id as compounds_id,
  reactions.id as reactions_id, 
  reaction_compound.number as reaction_compound_number  
FROM compounds, reactions, reaction_compound 
WHERE  
  compounds.id IN (68,74,112) 
  AND compounds.id = reaction_compound.compound  
  AND reactions.id = reaction_compound.reaction;

具体来说，我遇到的一些问题是在 Zend 中进行多个表连接。我不确定如何使用查询生成器跨多个表进行联接。

任何帮助表示赞赏！

喜欢的东西：

$compoundIds = array(68,74,112);
$select = $db->select()
   ->from('compounds', array('compounds_id' => 'id')
   ->where('compounds.id in ( ? )', $compoundIds)
   ->join('reaction_compound', 'compounds.id = reaction_compound.compound', array('reaction_compound_number' => 'number'))
   ->join('reactions', 'reactions.id = reaction_compound.reaction', array('reaction_id' => 'id');

那应该能让你到达某个地方。我没有测试过，所以里面可能有一些错误。
