mysql在哪里不使用左连接

多亏了一些帮助，我让左连接正常工作，但需要它根据记录是否处于活动状态来显示选定的结果。这些在记录中标记为Y或N

代码是

SELECT suppliers.ID, suppliers.Suppliername, suppliers.postcode, suppliers.address, 
    suppliers.phone, suppliers.fax, suppliers.email, suppliers.website, suppliers.imagename, 
    suppliers.Active, suppliers.RepID, repdetails.RepID, 
    repdetails.RepName, repdetails.RepEmail, repdetails.RepPhone 
FROM suppliers LEFT JOIN repdetails 
    ON suppliers.RepID = repdetails.RepID 
ORDER BY Suppliername ASC

它过去使用URL？Active=Y或？Active=N工作，但我不知道如何让它再次工作

任何帮助都将不胜感激，因为我是新手：）
