Question

insert into tbl_orderdetails (package_expiry,package_mocktest, package_section_test, package_video,  order_id, package_name, status,orderdetail_date) 
values                            (
( select package_exp from tbl_package where package_name = get_package_name),
( select package_mocktest_count from tbl_package where package_name = get_package_name),
( select package_section_count from tbl_package where package_name = get_package_name),
( select package_video_count from tbl_package where package_name = get_package_name),
 @orderId, get_package_name, 1, NOW());

从一张桌子中选择了这么多，有没有替代方案呢？非常感谢你的努力，并给了我一些宝贵的时间来改善我。抱歉，英语不好。

我怀疑你应该使用insert select这样的东西

insert into tbl_orderdetails 
(package_expiry,package_mocktest, package_section_test, package_video,  order_id, package_name, status,orderdetail_date) 
select package_exp ,
         package_mocktest_count,
         package_section_count, 
         package_video_count ,
         @orderId, get_package_name, 1, NOW())
from tbl_package where package_name = get_package_name

我想提高我的mysql查询虽然它工作正常，但需要一些帮助才能改进
