的MySQL對重複密鑰更新麻煩

Question

我有一個表

CREATE TABLE IF NOT EXISTS `b_sale_order_props_value` (
    `ID` int(11) NOT NULL AUTO_INCREMENT, 
    `ORDER_ID` int(11) NOT NULL, 
    `ORDER_PROPS_ID` int(11) DEFAULT NULL, 
    `NAME` varchar(255) COLLATE utf8_unicode_ci NOT NULL, 
    `VALUE` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL, 
    `CODE` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL, 
    PRIMARY KEY (`ID`), 
    UNIQUE KEY `IX_SOPV_ORD_PROP_UNI` (`ORDER_ID`,`ORDER_PROPS_ID`) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1921 ; 

我做一個查詢

INSERT INTO `b_sale_order_props_value` 
    SET `ORDER_ID`=316, 
     `ORDER_PROPS_ID`=30, 
     `NAME`='ADDRES', 
     `VALUE`='Test addres' 
    ON DUPLICATE KEY UPDATE `NAME`='ADDRES',`VALUE`='Test addres'; 

返回一個錯誤

Duplicate entry '316-30' for key 'IX_SOPV_ORD_PROP_UNI' 

如何解決這個麻煩？

太大發布的評論 - 您的疑問在這裏工作：

mysql> use test; 
Reading table information for completion of table and column names 
You can turn off this feature to get a quicker startup with -A
