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

在mysql5中,能夠設置safe mode,好比在一個更新語句中

UPDATE table_name SET bDeleted=0;

執行時會錯誤,報:

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

  緣由是在safe mode下,要強制安全點,update只能跟where了,

要取消這個限制,能夠:

    SET SQL_SAFE_UPDATES=0;

便可
