Get Tables List With Its Dependent Tables Names
This script is useful to find dependent table list in SQL Server 2005,2008. It is more useful when we have to prepare cleanup script for database which has large number of tables and lots of dependence on other tables.
 
We can identify then which table is dependent on which tables, so we can easlly write cleanup query and also we can easily identify master tables.
 
SQL Query as below:
-- Declare Variables
DECLARE @mastertable VARCHAR(100)
DECLARE @TableCompleteName VARCHAR(100)
DECLARE @tablesname VARCHAR(1000)
-- declare temp table which is used for storing table name and dependent table list
CREATE TABLE #temptable
    (
      tablecompletename VARCHAR(100),
      tablename VARCHAR(1000)
    )
 
--  get all table name from sys objects 
DECLARE tmp_cur CURSOR static
    FOR SELECT  s.name + '.' + o.name,
                o.name
        FROM    sys.objects o
                INNER JOIN sys.schemas s ON o.schema_id = s.schema_id
        WHERE   type = 'U'
        ORDER BY s.name,
                o.name
 -- fetch all table name    
OPEN tmp_cur
      --FETCH

-- get fetch one by one table name and it's dependent table name     
FETCH FIRST FROM tmp_cur INTO @TableCompleteName, @mastertable
WHILE @@FETCH_STATUS = 0
    BEGIN
 
        --
        SELECT  @tablesname = COALESCE(@tablesname + ',', '') + s.name + '.'
                + OBJECT_NAME(FKEYID)
        FROM    SYSFOREIGNKEYS
                INNER JOIN sys.objects o ON o.object_id = SYSFOREIGNKEYS.fkeyid
                INNER JOIN sys.schemas s ON s.schema_id = o.schema_id
        WHERE   OBJECT_NAME(RKEYID) = @mastertable
                 
        INSERT  INTO #temptable
                (
                  tablecompletename,
                  tablename
                )
                SELECT  @TableCompleteName,
                        COALESCE(@tablesname, '')
        SELECT  @tablesname = NULL
        FETCH NEXT FROM tmp_cur INTO @TableCompleteName, @mastertable
    END
   
SELECT  tablecompletename AS TableName, tablename AS DependentTables
FROM    #temptable 
 
DROP TABLE #temptable
 
CLOSE tmp_cur
DEALLOCATE tmp_cur
