mysql update limit mysql更新限制語句用法

來源:互聯網

mysql更新時,要更新記錄中某個區間的資料,只能用WHERE條件來限制了,

用LIMIT只能限制更新多少條!測試如下:

UPDATE products SET goods_number = goods_number+10 ORDER BYgoods_id DESC LIMIT 5,10

上面這句測試了是錯誤的,MYSQL的UPDATE語句不能更新限制從第幾條到第幾條!

錯誤提示:#1064 - You have an error in your SQL syntax; check the manualthat corresponds to your MySQL server version for the right syntaxto use near '10' at line 1

只能用下面這樣的語句了,要麼你就用where條件陳述式來限制了

UPDATE products SET goods_number = goods_number+10 ORDER BYgoods_id DESC LIMIT 10
