php - 如何在同一个查询中使用 INNER JOIN 和 IN Clause

Question

我有三个表，想对它们运行 INNER JOIN 和 IN 子句。谁能告诉我哪里做错了

    SELECT `tblinvoices`.id,`tblinvoices`.userid,`firstname`,`lastname`
            FROM `tblinvoices`
WHERE `paymentmethod`IN 
(SELECT  `gateway` FROM  `tblpaymentgateways` WHERE  `setting`='type' AND `value` = 'CC') 
INNER JOIN `tblclients` ON `tblinvoices`.userid=`tblclients`.id"

Answer 1

JOIN 出现在 WHERE 之前:

SELECT     tblinvoices.id,
           tblinvoices.userid,
           firstname,
           lastname
FROM       
           tblinvoices

INNER JOIN tblclients
        ON tblinvoices.userid = tblclients.id
WHERE      
      paymentmethod IN
           (select gateway
            FROM   tblpaymentgateways
            WHERE  setting='type'
             AND   value = 'CC')
