查询失败并出现一些问题。

错误1064（42000）：您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在resignationForm.emp_id = immcf.emp_id＆＃39;上使用“左边连接immcf”附近的正确语法。在第1行

Answer 1

您有多个WHERE子句，这是不允许的。并且WHERE子句必须在所有JOIN和FROM子句之后编写。您的订单为WHERE，LEFT JOIN，WHERE。

Answer 2

你在Where子句之后做左联接。首先，您需要编写所有连接，然后编写Where子句。

"....where mlj.name is not null  left join immcf on resi...."

我得到一个查询问题
