我的灯具表应该具有什么设计才能从下拉列表中选择并显示两个团队？

Question

团队表

   TeamID (PK)
   TeamName 
   CoachID  (FK)

固定表格

 FixtureID  (PK)
 Venue    
 Team1    (FK) to TeamTable
 Team2     (FK) to TeamTable
 FixtureDate

我已经创建了一个存储过程

CREATE PROCEDURE [dbo].[PR_Fixture_SelectAll]
AS
    SELECT
        [dbo].[Fixture].[FixtureID],
        [dbo].[Fixture].[Venue],
        [dbo].[Fixture].[Team1],
        [dbo].[Fixture].[Team2],
        [dbo].[Fixture].[FixtureDate],
        [dbo].[Team].[TeamName]
    FROM 
        [dbo].[Fixture] 
    INNER JOIN
        [dbo].[Team] ON [dbo].[Team].[TeamID] = [dbo].[Fixture].[Team1]
    INNER JOIN
        [dbo].[Team] t ON[dbo].[Team].[TeamID] = [dbo].[Fixture].[Team2]    

存储过程在执行时仅显示列名，而不显示插入的数据

这可能对您有帮助

DECLARE @Team TABLE
(
   TeamID INT  ,
   TeamName VARCHAR(50),
   CoachID INT 
)

DECLARE @Fixture Table
(

    FixtureID INT,
    Venue VARCHAR(50),
    Team1 INT ,
    Team2 INT,
    FixtureDate DATE

)

INSERT INTO @Team(TeamID,TeamName,CoachID) VALUES(1,'A',1)
INSERT INTO @Team(TeamID,TeamName,CoachID) VALUES(2,'B',2)
INSERT INTO @Team(TeamID,TeamName,CoachID) VALUES(3,'C',3)
INSERT INTO @Team(TeamID,TeamName,CoachID) VALUES(4,'D',4)

INSERT INTO @Fixture(FixtureID,Venue,Team1,Team2,FixtureDate) VALUES(1,'X',1,3,GETDATE())
INSERT INTO @Fixture(FixtureID,Venue,Team1,Team2,FixtureDate) VALUES(2,'Y',2,4,GETDATE())

SELECT
        f.FixtureID,
        f.Venue,
        t1.TeamName Team1,
        t2.TeamName Team2,
        f.FixtureDate
FROM @Fixture f
Inner Join @Team t1 ON  f.Team1 = t1.TeamID 
Inner Join @Team t2 ON  f.Team2 = t2.TeamID
