爲什麼我的查詢顯示的錯誤有關的關鍵字附近有語法錯誤「其中」

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用於正確但它顯示了以下錯誤...

關鍵字「附近哪裏有語法錯誤」。

Answer 1

您需要使用UPDATE

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

Answer 2

我想你想的update查詢：

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

Answer 3

語法大量插入：

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