mysql - SQL 选择多个 AND

Question

我有一个很长的 sql 语句，我试图向其中添加一些 AND 条件，但它不起作用。

这是我的声明:

if($cat=="att") { $sqlCatC = "INNER JOIN yt_att_data CAT
    ON CAT.busID = R.id AND CAT.subcatID = 5 AND CAT.subcatID = 136 AND CAT.deleted = 0"; }

//Get RegionInfo busID based on region, approved
    $sql= "SELECT DISTINCT CAT.busID,R.id,companyName,membershipID,addressID,city,logo,descriptionShort FROM yt_Business_RegInfo R
    $sqlReg
    INNER JOIN yt_Business_Seasons S
    ON R.id = S.busID AND S.deleted = 0
    INNER JOIN yt_Business_Address A
    ON R.addressID = A.id
    INNER JOIN yt_Business_Membership M
    ON R.membershipID = M.id AND M.approved = 1
    $sqlCatC
    WHERE R.deleted = 0
    ORDER BY R.companyName ASC LIMIT $start, $limit";

在顶部 $sqlCatC 中，我尝试添加一个 AND 条件，其中 CAT.subcatID 等于 5 和 136。它适用于检查单个 CAT.subcatID，但不适用于两个。如有任何建议，我们将不胜感激。

Answer 1

使用 IN 关键字，如下所示:

CAT.subcatID IN(5,136)

替换你的两个AND。
