使用 Table 值函数加入

Question

如何在 MSSql 2012 中使用 table 值函数进行连接，如下面的查询？

SELECT  m1.id, m1.oid, m1.id2
FROM    dbo.Match(484066) AS m1 INNER JOIN
        dbo.Match(m1.id2) AS m2 ON m1.id2 = m2.id INNER JOIN
        dbo.Match(m2.id2) AS m3 ON m2.id2 = m3.id AND m1.id = m3.id2

Answer 1

SELECT  m1.id, m1.oid, m1.id2
FROM    dbo.Match(484066) AS m1 CROSS APPLY
        dbo.Match(m1.id2) AS m2 CROSS APPLY
        dbo.Match(m2.id2) AS m3
