mysql中使用存儲過程更新表

Question

我在mysql中存儲過程。該過程被創建，但是當程序被稱爲我得到一個錯誤：

"Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences -> SQL Editor -> Query Editor and reconnect."

下面是該過程：

------------------------------------------------ 
drop procedure if exists update_per_det; 

delimiter // 

create procedure update_per_det(IN name varchar(30)) 

begin 

DECLARE age1 int; 

set age1=(select CalAge(name)); 

update per_det set age=age1 where username=name; 

end;// 

delimiter ; 

我怎樣才能解決這個問題呢？

Answer 1

試試這個：

set age1=(select CalAge(name)); 

SET SQL_SAFE_UPDATES=0; 

update per_det set age=age1 where username=name;
