将超级海量查询从SQL Server转换为MySQL-连接问题

我有一个在SQLServer2008中运行良好的查询，但当我尝试将它与MySQL一起使用时，它似乎在

JOIN

中出现了问题

第一个错误是

您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解可在第52行的“ON faxcont.IDDireccion=dir_cont.RecID和faxcont.Tipo=2和faxcont.Defecto”上使用的正确语法

如何纠正这一点

编辑

在下面附加格式化代码，使用：

---

从前两个表开始，将它们连接在一起-

requerimientos AS req INNER JOIN
requerimientositems AS req_dp ON req.RecID = req_dp.IDRequerimiento'

如果可行（编写一个涉及两个表的查询[即测试]，并确保其正常），则在中添加下一个查询-

requerimientos AS req INNER JOIN
requerimientositems AS req_dp ON req.RecID = req_dp.IDRequerimiento INNER JOIN 
moneda AS mon ON req.NroMoneda = mon.Numero INNER JOIN
contactos AS cont ON req.IDRef = cont.IDContacto

然后重复

---

这可能需要一点努力，但这是一种敏捷的方法，将极大地帮助您前进。
“特别是那种面食；）

如果这样做有效和/或您想尝试更大的跳转，请尝试删除这些子选择，看看这是否是问题所在：
删除：

LEFT OUTER JOIN
  (SELECT IDRequerimiento
   FROM pedidos AS ped
   GROUP BY IDRequerimiento) AS ped_1 ON req.RecID = ped_1.IDRequerimiento
LEFT OUTER JOIN
  (SELECT RecID
   FROM pedidos AS ped2
   GROUP BY RecID) AS ped2_1 ON req.IDPedido = ped2_1.RecID  

---

最后，根据实际的错误通知，看这里：！！！

AND telcont.Tipo = 3
AND telcont.Defecto = 1 ON faxcont.IDDireccion = dir_cont.RecID
AND faxcont.Tipo = 2

---

在？
