sql - 使用 SQL Server 中的条件从存储过程中调用存储过程的正确语法是什么

Question

我在从存储过程中调用存储过程时弄乱了条件语句。谁能帮帮我？

    CREATE PROCEDURE [dbo].[sp_Leaderboard] 

    @CompetitionId INTEGER

    AS

    DECLARE @Competition TABLE
    (CompId INTEGER,
    CompFormat NVARCHAR(10)
    )
    INSERT INTO @Competition
    SELECT CompetitionId, CompetitionFormatType
    FROM dbo.Competitions 
LEFT JOIN dbo.CompetitionFormat ON dbo.Competitions.CompetitionFormatId = dbo.CompetitionFormat.CompetitionFormatId
    WHERE CompetitionId = @CompetitionId


    CASE WHEN @Competition.CompFormat = "Strokes" THEN EXEC [dbo].[sp_Strokes] ELSE EXEC [dbo].[sp_Stableford]

此外，我知道我的代码中没有满足的一点是，我还需要将参数@CompetitionId 带入我执行的任何过程。

为什么不直接使用 IF 语句呢？

IF (SELECT TOP 1 CompFormat FROM @Competition) = 'Strokes'
   BEGIN
       EXEC [dbo].[sp_Strokes] @CompetitionId 
   END
ELSE
   BEGIN
       EXEC [dbo].[sp_Stableford] @CompetitionId 
   END
