插入重复密钥并替换为不工作

CREATE TABLE `pv_network_coverage` (
    `network_group_id` int(8) NOT NULL, 
    `carrier_group_id` int(8) NOT NULL, 
    `physician_count` int(8) NOT NULL DEFAULT '0', 
    `facility_count` int(8) NOT NULL DEFAULT '0', 
    `pcp_count` int(8) NOT NULL DEFAULT '0', 
    `update_time` datetime NOT NULL, 
    PRIMARY KEY (`network_group_id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_cs; 

REPLACE INTO pv_network_coverage(carrier_group_id, 
           network_group_id, 
           physician_count, 
           facility_count, 
           pcp_count, 
           update_time) SELECT *FROM temp_pv_network_coverage;

我使用replace into和insert into带有重复键。插入重复密钥并替换为不工作

的physician_count应该是1000，但仍0 ..
