sql函数无法编译

问题描述

亲爱的所有朋友



过去四小时我遇到过一个问题，但直到找到合适的解决办法才能解决问题。

Dear All friends

I have faced one problem last four hour's, but can't until find proper solution.

alter function _swap_row_value
()
returns @temp table
(
id int not null,
salary int not null,
name varchar(max) not null,
sex varchar(max) not null
)
as
begin
insert into @temp(salary,name,sex) select t.salary,t.name,t.sex  from top5 t
update @temp set sex= case sex when 'm' then 'f' when 'f' then 'm'
return;
end;

错误显示如下类型：消息156，级别15，状态1，过程_swap_row_value，第14行

关键字'return'附近的语法不正确。



桌面结构5

Error show like this type : Msg 156, Level 15, State 1, Procedure _swap_row_value, Line 14
Incorrect syntax near the keyword 'return'.
