多表查询

一、多表查询 (Get ModelOptions Not Linked To Color)

需求： 有以下三张表，查询出vehiclemodel_vehiclemodeloptions中的op3的那一行记录。

（该记录不在第二个表中有关联的color,同时该记录存在同一个VehicleModel_id）

SELECT * FROM test.vehiclemodel_vehiclemodeloptions;

SELECT * FROM test.dictionary_color;

SELECT * FROM test.vehiclemodel_dictionarycolorreferences;

参考答案：

SELECT 
    t3.DICTIONARY_OPTION_REFERENCE
FROM
    test.vehiclemodel_vehiclemodeloptions t3
where
    t3.VehicleModel_id = 1
        and t3.DICTIONARY_OPTION_REFERENCE not in (SELECT distinct
            t2.DICTIONARY_OPTION_REFERENCE
        FROM
            test.dictionary_color t2
        where
            t2.id in (SELECT 
                    t1.dictionaryColorReferences
                FROM
                    test.vehiclemodel_dictionarycolorreferences t1
                where
                    t1.VehicleModel_id = 1))
