Question

我有以下问题我想从feature_values表中选择product_id，其中variant_id等于多个值

我有这个

SELECT product_id FROM feature_values WHERE variant_id = '162' AND variant_id = '11819'

以上不会返回结果

以下两个查询返回product_id

SELECT product_id FROM feature_values WHERE variant_id = '162'

和这个

SELECT product_id FROM feature_values WHERE variant_id = '11819'

表示例数据

Feature ID, Product ID, Variant ID, Value
        92,        565,      11815
        69,        565,        162
        92,        566,      11819
        69,        566,        162

Answer 1

SELECT product_id FROM feature_values WHERE variant_id = '162' OR variant_id = '11819'

或

SELECT product_id FROM feature_values WHERE variant_id in ('162','11819')

Answer 2

尝试这些，并不是你想要的，想想逻辑变体id可以是一个或另一个，而不是两个同时。

SELECT product_id FROM feature_values WHERE variant_id IN ('162', '11819')

OR

SELECT product_id FROM feature_values WHERE variant_id = '162' OR variant_id = '11819'

查询基于具有多个值的第二列查找具有多个条目的ID？
