Question

我有这个存储过程：

CREATE PROCEDURE [dbo].[sp_get_correct_responses]       
    @QuestionUId    UNIQUEIDENTIFIER
AS
BEGIN
        ...

    -- This is the last part of the SP. I need to use the output 
    -- value of @AnswerGridCorrect in the calling SP
    SELECT  @AnswerGridCorrect = Correct
    FROM    Concatenated
    WHERE   RowNumber = ColumnCount

END

如何从另一个存储过程调用存储过程，传递@QuestionUId参数并将返回的变量@AnswerGridCorrect放入调用过程中声明的变量中？

更新：这是建议的答案：

 CREATE PROCEDURE [dbo].[sp_get_correct_responses]       
    @QuestionUId    UNIQUEIDENTIFIER,
    @output VARCHAR(20) output
AS
BEGIN

select @QuestionUId

    DECLARE @AnswerGridCorrect VARCHAR(20)
    DECLARE @QuestionId int;

    SELECT @QuestionId = QuestionId
    FROM dbo.Question 
    Where QuestionUId = @QuestionUId;

    Select @questionId;

    WITH Partitioned AS (
        SELECT  ROW_NUMBER() OVER (PARTITION BY QuestionId ORDER BY AnswerId ASC) AS RowNumber,
                COUNT(1) OVER (PARTITION BY QuestionId) AS ColumnCount,
                CONVERT(VARCHAR(MAX), Correct) AS Correct
        FROM    dbo.Answer
        WHERE   [QuestionId] = @QuestionId
    ),
    Concatenated AS (
        SELECT RowNumber, ColumnCount, Correct FROM Partitioned WHERE RowNumber = 1 
        UNION ALL   
        SELECT      P.RowNumber,
                    P.ColumnCount,
                    C.Correct + P.Correct AS Correct
        FROM        Partitioned P
        INNER JOIN  Concatenated C
        ON          P.RowNumber = C.RowNumber + 1
    )

    SET @output = (SELECT  Correct
                   FROM    Concatenated
                   WHERE   RowNumber = ColumnCount)
    RETURN

END

Answer 1

您可以在父SP中创建一个表变量，并在下面插入子SP的结果：

DECLARE @TempTable TABLE(AnswerGridCorrect INT)
INSERT INTO @TempTable 
EXEC [dbo].[sp_get_correct_responses] @QuestionUId

Answer 2

您可以在另一个存储过程中使用临时表，并使用此结果填充它：

INSERT INTO #table
Exec sp_get_correct_responses @QuestionUId

另一种方法是修改sp_get_correct_responses以产生输出，因为您只需要一个值。

CREATE PROCEDURE [dbo].[sp_get_correct_responses]       
    @QuestionUId    UNIQUEIDENTIFIER,
    @output VARCHAR(20) output
AS
BEGIN
        ...

    -- This is the last part of the SP. I need to use the output 
    -- value of @AnswerGridCorrect in the calling SP
    SELECT @output = Correct
    FROM    Concatenated
    WHERE   RowNumber = ColumnCount
    RETURN

END

在你的其他SP中：

DECLARE @output VARCHAR(20)
EXEC sp_get_correct_responses
  @QuestionUId,
  @output output

SELECT @output

如何从另一个存储过程调用并获取SP的结果
