sql - 为什么我的查询在关键字“where”附近显示错误语法

Question

insert into general_info(desig) 
values('professor') 
where g_id = (select h_gid from hasj where h_userid = 'U001');

所有表和列 r 使用正确，但它显示以下错误...

关键字“where”附近的语法不正确。

Answer 1

你需要使用UPDATE

UPDATE general_info
set desig= 'professor'
where g_id in (select h_gid from hasj where h_userid = 'U001');

Answer 2

我想你想要一个update查询：

update general_info set
desig = 'professor'
where g_id in (select h_gid from hasj where h_userid = 'U001');

Answer 3

批量插入的语法：

INSERT INTO Table(...)  
SELECT ... FROM ... WHERE ...
