Question

我有以下SQL查询：

INSERT INTO site_city_address (`cityName`, `cityCode`, `stateId`) VALUES  (SELECT a.city, a.cityCode,  b.stateId
  FROM site_address_dropdown a INNER JOIN site_state_address b
    ON a.state = b.stateName);

我知道这可能是错的。我想要做的是将a.city，a.cityCode和b.stateId的值作为cityName，cityCode和stateId插入shopious_city_address。我该怎么做？

Answer 1

您可以在values后指定select或insert。在您的情况下，省略values：

INSERT  INTO site_city_address
        (`cityName`, `cityCode`, `stateId`) 
SELECT  a.city, a.cityCode, b.stateId
FROM    site_address_dropdown a 
INNER JOIN 
        site_state_address b
ON      a.state = b.stateName;

Answer 2

删除VALUES关键字。 INSERT INTO...SELECT具有以下语法

INSERT INTO site_city_address (cityName, cityCode, stateId) 
SELECT  a.city, a.cityCode, b.stateId
FROM    site_address_dropdown a 
        INNER JOIN site_state_address b
            ON a.state = b.stateName

从select语句向表中插入值
