mysql中使用存储过程更新表

Question

我在mysql中存储过程。该过程被创建，但是当程序被称为我得到一个错误：

"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."

下面是该过程：

------------------------------------------------ 
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 ; 

我怎样才能解决这个问题呢？

Answer 1

试试这个：

set age1=(select CalAge(name)); 

SET SQL_SAFE_UPDATES=0; 

update per_det set age=age1 where username=name;
