SQL Server表關係

Question

SQL Server Mgmt Studio 2005：有人可以幫助我瞭解如何查看和打印表之間的關係，同時顯示錶中的列。我很多年前就做過這個事情，並且一直在努力掙扎幾天才能再做一次。

Answer 1

右鍵單擊數據庫名稱，展開「數據庫關係圖」並選擇：「新建數據庫關係圖」。

Answer 2

您可以創建數據庫圖並將所有表添加到它。這將是一個圖形表示，如果這是你想要的。

Answer 3

您需要創建和編輯數據庫圖表，請參閱本Getting started with SQL Server database diagrams和/或Designing Database Diagrams

您可以查詢做得一樣好：SQL SERVER – Query to Display Foreign Key Relationships and Name of the Constraint for Each Table in Database

這裏是一個查詢，將得到的PK;檢查約束和FKS，並從@tablename，多列約束在一個逗號分隔的列表：

DECLARE @TableName varchar(250) 
SET @TableName='YourTable' 
;WITH AllInfo AS 
(
SELECT 
    tc.TABLE_NAME,tc.CONSTRAINT_NAME, ccu.COLUMN_NAME 
    FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS     tc 
     INNER JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE ccu ON ccu.TABLE_NAME = tc.TABLE_NAME AND ccu.CONSTRAINT_NAME = tc.CONSTRAINT_NAME 
    WHERE tc.TABLE_NAME =@TableName 
UNION 
SELECT 
    FK.TABLE_NAME,C.CONSTRAINT_NAME,CU.COLUMN_NAME 
    FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS  C 
     INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME 
     INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME 
     INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME 
     INNER JOIN (SELECT i1.TABLE_NAME, i2.COLUMN_NAME 
         FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS   i1 
          INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2 ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME 
          WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY' 
        ) PT ON PT.TABLE_NAME = PK.TABLE_NAME 
     WHERE PK.TABLE_NAME=@TableName 
) 
SELECT DISTINCT 
    t1.TABLE_NAME,t1.CONSTRAINT_NAME 
     ,STUFF(
        (SELECT 
         ', ' + t2.COLUMN_NAME 
         FROM AllInfo t2 
         WHERE t1.TABLE_NAME=t2.TABLE_NAME AND t1.CONSTRAINT_NAME=t2.CONSTRAINT_NAME 
         ORDER BY t2.COLUMN_NAME 
         FOR XML PATH(''), TYPE 
        ).value('.','varchar(max)') 
        ,1,2, '' 
      ) AS ColumnNames 
    FROM AllInfo t1 
    ORDER BY 1,2,3
