【问题描述】：

谁能告诉我这里的语法错误是什么：

SELECT T.id,T.vmProductID,T.name AS Course,C.title AS Category FROM j25_lms_tests AS T LEFT JOIN j25_lms_categories AS C ON C.id = T.catid WHERE T.published=1 AND T.vmProductID IN() ORDER BY T.ordering

这是脚本的主要代码： 'SELECT T.id,T.vmProductID,T.name AS Course,C.title AS Category FROM #__lms_tests AS T 左连接 #__lms_categories AS C.id = T.catid WHERE T.published=1 AND T.vmProductID IN($vmProductIds) $Catwhere ORDER BY T.ordering";'

谁能告诉我代码有什么问题。

提前谢谢你

【问题讨论】：

T.vmProductID IN() 中的内容在那里缺少值。
Hello Abhik, 'SELECT T.id,T.vmProductID,T.name AS Course,C.title AS Category FROM #__lms_tests AS T LEFT JOIN #__lms_categories AS C.id = T. catid WHERE T.published=1 AND T.vmProductID IN($vmProductIds) $Catwhere ORDER BY T.ordering";'我将 T.vmProductID IN($vmProductIds) 更改为 T.vmProductID IN('$vmProductIds') 并且它工作但不确定我所做的是否正确谢谢
