Question

我正在使用SQL Server，我有2个存储过程：

第一个存储过程：

CREATE PROCEDURE A
AS
    SELECT DISTINCT 
        TC.*,       MS.*
    FROM
        VIEW1 TC,
        View2 MS
    WHERE
        TC.ID = MS.ID
    ORDER BY
        TC.Type ASC

第二个存储过程：

CREATE PROCEDURE B
AS
    SET NOCOUNT ON

    SELECT DISTINCT
        TC.*, MS.*
    FROM
        VIEW3 TC,
        VIEW2 MS
    WHERE
        C.ID = MS.ID 
    ORDER BY 
        MS.Date DESC

我想获取这两个存储过程的数据结果，然后将其绑定到gridview。我创建了以下存储过程，但它抛出了ID列无效的错误：

CREATED PROCEDURE C
AS
    SET NOCOUNT ON

    SELECT DISTINCT
        TC.*, MS.*
    FROM
        (VIEW1 TC
    LEFT JOIN 
        VIEW2 MS ON MS.ID = TC.ID)

    UNION 

    SELECT DISTINCT
        TC1.*, MS.*
    FROM
        (VIEW3 TC1
    LEFT JOIN
        VIEW2 MS on MS.ID = TC1.ID)

如何组合2个存储过程的数据结果？仅供参考，所有列都是从视图中选择的，而不是表格。

Answer 1

在存储过程编号3中，您使用的是括号错误，它应该是这样的

CREATE PROCEDURE C
AS    
    SELECT DISTINCT
        TC.*, MS1.*
    FROM
        VIEW1 TC
    LEFT JOIN 
        VIEW2 MS1 ON MS1.ID = TC.ID

    UNION 

    SELECT DISTINCT
        TC2.*, MS2.*
    FROM
        VIEW3 TC2
    LEFT JOIN
        VIEW2 MS2 on MS2.ID = TC2.ID

您还可以将存储过程的结果插入临时表，然后显示临时表的结果：

CREATE TABLE #tempA(Column1 NVARCHAR(50),Column2 NVARCHAR(50),...)

INSERT INTO #tempA ( Column1, Column2, ... )
 EXEC A

INSERT INTO #tempA (Column1, Column2, ...)
 EXEC B

SELECT * FROM #tempA

Answer 2

如果您不想复制代码，请创建一个结果表，如

CREATE PROCEDURE C
AS
    CREATE TABLE #foo (bar int ...)

     INSERT INTO #foo EXEC A
     INSERT INTO #foo EXEC B

     SELECT * FROM #foo
     DROP TABLE #foo

如果列具有相似的数据类型，则只需单击查询

CREATE PROCEDURE C
AS
    SELECT A.* FROM
    (
        SELECT DISTINCT 
            TC.*,       MS.*
        FROM
            VIEW1 TC,
            View2 MS
        WHERE
            TC.ID = MS.ID
        ORDER BY
            TC.Type ASC
    ) A
    UNION ALL
    SELECT B.* FROM
    (
        SELECT DISTINCT
            TC.*, MS.*
        FROM
            VIEW3 TC,
            VIEW2 MS
        WHERE
            C.ID = MS.ID 
        ORDER BY 
            MS.Date DESC
    ) B
