sql - 一个需要创建复杂的sql语句

Question

我有两张桌子。

table A
id
isReachEnd

---

table B
id
isFree

我需要获取所有满足下一个标准的 id：

((A.id = B.id) AND (A.isReachEnd = 1) AND (B.isFree = 1))

我能怎么做？

Answer 1

这一点都不复杂——事实上，它非常简单。查询将只是

SELECT * FROM a, b WHERE a.id = b.id AND a.isReachEnd = 1 AND b.isFree = 1

Answer 2

SELECT *
FROM A, B
WHERE A.id = B.id AND A.isReachEnd = 1 AND B.isFree = 1
