将子查询作为函数参数传递

Question

如何将子查询作为函数参数

运行

 select  get_feeTypeamount(SELECT ftp.type_plan_id 
                 FROM tbl_fee_type_plan ftp
       WHERE ftp.type_plan_id=17) as total_amount

Answer 1

您不需要子查询。只需将该功能应用到ftp.type_plan_id。{/ p>中的SELECT列即可

这样的事情对你有用：

SELECT get_feeTypeamount(ftp.type_plan_id) as total_amount 
FROM tbl_fee_type_plan ftp
WHERE ftp.type_plan_id=17
