SQL Server 2000 - requête relations clés étrangères d'une table

Question

presque identique à Query a Table's Foreign Key relationships, mais pour SQL Server 2000

Pour une table donnée « foo », je besoin d'une requête pour générer une série de tableaux qui ont étranger les touches qui pointent vers foo.

Answer 1

SELECT o2.name 
FROM sysobjects o 
INNER JOIN sysforeignkeys fk on o.id = fk.rkeyid 
INNER JOIN sysobjects o2 on fk.fkeyid = o2.id 
WHERE o.name = 'foo' 

Answer 2

Commencez ici

SELECT cons.TABLE_NAME 
    , cons.CONSTRAINT_NAME PK_NAME 
    , cols.COLUMN_NAME 
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS cons 
LEFT join INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE cols 
ON cons.CONSTRAINT_NAME = cols.CONSTRAINT_NAME 
WHERE cons.CONSTRAINT_TYPE = 'foreign KEY' 
ORDER BY cons.TABLE_NAME 
    , cons.CONSTRAINT_NAME 
    , cols.COLUMN_NAME

Answer 3

Essayez ce T-SQL:

select col_name(fkeyid, fkey) as column_name, object_name(rkeyid) as referenced_table_name, col_name(rkeyid, rkey) as referenced_column_name from sysforeignkeys where object_name(fkeyid) = 'tableNameHere' order by constid 

J'ai réécrit légèrement la requête pour vous donner toutes les autres tables qui dépendent d'une table particulière:

select object_name(fkeyid), 
col_name(fkeyid, fkey) as column_name, 
col_name(rkeyid, rkey) as referenced_column_name 
from sysforeignkeys 
where object_name(rkeyid) = 'tableNameHere' 
order by constid

/* this will find out all of the foreign key references for a table*/ 

DECLARE @tableName varchar(128) 
SET @tableName = 'tCounter' 

SELECT 
    pt.[name] AS 'parentTable', 
    ct.[name] AS 'childTable', 
    fk.[name] AS 'fkName', 
* 
FROM sys.foreign_keys fk   
    INNER JOIN sys.tables pt    
     ON pt.object_ID = fk.parent_object_id   
    INNER JOIN sys.tables ct    
     ON ct.object_ID = fk.referenced_object_id 
WHERE pt.name = @tableName  
    OR ct.name = @tableName 
ORDER BY pt.name, ct.name
