rror Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that

在mysql5中,可以设置safe mode,比如在一个更新语句中

UPDATE table_name SET bDeleted=0;

执行时会错误,报:

You are using safe update mode and you tried to update a table without a WHERE clause that uses a KEY column.”

原因是在safe mode下,要强制安全点,update只能跟where了,

要取消这个限制,可以:

SET SQL_SAFE_UPDATES=0;

即可
