SQLServer2005查询问题

我有一个包含以下字段的表

• 监督员
• 埃皮德

这就像是一个推荐计划。一个人可以推荐他下面的三个人，即， 3指的是三个人，即458，同样4指的是910，11，同样8指的是12，13，是这样的

---

我想要一个查询来获得一个家伙下面的下线成员总数，比如说3，你可以使用递归

像这样的

DECLARE @Table TABLE(
        Supervisorid INT,
        Empid INT
)

INSERT INTO @Table SELECT 3, 4
INSERT INTO @Table SELECT 3, 5
INSERT INTO @Table SELECT 3, 8

INSERT INTO @Table SELECT 4, 9
INSERT INTO @Table SELECT 4, 10
INSERT INTO @Table SELECT 4, 11

INSERT INTO @Table SELECT 8, 12
INSERT INTO @Table SELECT 8, 13

DECLARE @ID INT
SELECT  @ID = 3

;WITH Vals AS (
        SELECT  *
        FROM    @Table
        WHERE   SuperVisorID = @ID
        UNION ALL
        SELECT  v.SuperVisorID,
                t.Empid
        FROM    Vals v INNER JOIN
                @Table t    ON  v.Empid = t.Supervisorid
)
SELECT  SuperVisorID,
        COUNT(Empid) Total
FROM    Vals
GROUP BY    SuperVisorID

您可以使用递归

像这样的

DECLARE @Table TABLE(
        Supervisorid INT,
        Empid INT
)

INSERT INTO @Table SELECT 3, 4
INSERT INTO @Table SELECT 3, 5
INSERT INTO @Table SELECT 3, 8

INSERT INTO @Table SELECT 4, 9
INSERT INTO @Table SELECT 4, 10
INSERT INTO @Table SELECT 4, 11

INSERT INTO @Table SELECT 8, 12
INSERT INTO @Table SELECT 8, 13

DECLARE @ID INT
SELECT  @ID = 3

;WITH Vals AS (
        SELECT  *
        FROM    @Table
        WHERE   SuperVisorID = @ID
        UNION ALL
        SELECT  v.SuperVisorID,
                t.Empid
        FROM    Vals v INNER JOIN
                @Table t    ON  v.Empid = t.Supervisorid
)
SELECT  SuperVisorID,
        COUNT(Empid) Total
FROM    Vals
GROUP BY    SuperVisorID

考虑重新措词/格式化你的问题。很难理解。谢谢@OMG Ponies.：）仍然很难理解第二段THO（不是因为格式化，而是因为措辞不好）。考虑重新措词/格式化你的问题。很难理解。谢谢@OMG Ponies.：）第二段仍然很难理解（不是因为格式，而是因为措词不当）。
