mysql：如何使用另一个表的两个不同值从一个表中选择两个不同的列值

Question

My goal is to select two different values,say c & d from table2 using the fields a and b of table1 in a single query.

Any help would be deeply appreciated.

Thanks.

Answer 1

SELECT table2.c, table2.d
FROM table2
JOIN table1 ON table2.some_common_field = table1.other_common_field
WHERE (table1.a = XXX) AND (table1.b = YYY)
