There are lot of tables and sp in the db. I find the tables name which are used in the specific sp (stored procedure).
sp_depends %sp_name%

The two highest voted answers use a lot of deprecated tables that should be avoided.
Here's a much cleaner way to do it.
SELECT DISTINCT p.name AS proc_name, t.name AS table_name
FROM sys.sql_dependencies d
INNER JOIN sys.procedures p ON p.object_id = d.object_id
INNER JOIN sys.tables t ON t.object_id = d.referenced_major_id
ORDER BY proc_name, table_name
Works with MS SQL SERVER 2005+
object_id
instead of id
referenced_major_id
instead of depid
o.xtype = 'p'
(etc.)Also, there is really no need for a CTE which uses ROW_NUMBER() just in order to make sure we only have one of each record set returned. That's what DISTINCT is there for!
I submit into evidence: Exhibit A. The following queries have the same Execution Plan!
-- Complex
WITH MyPeople AS (
SELECT id, name,
ROW_NUMBER() OVER(PARTITION BY id, name ORDER BY id, name) AS row
FROM People)
SELECT id, name
FROM MyPeople
WHERE row = 1
-- Better
SELECT DISTINCT id, name
FROM People
SELECT
NAME
FROM SYSOBJECTS
WHERE ID IN ( SELECT SD.DEPID
FROM SYSOBJECTS SO,
SYSDEPENDS SD
WHERE SO.NAME = 'SP_NAME'
AND SD.ID = SO.ID
)

But please note that the sysdepends
will not give the table names if they are used in dynamic sql. What I suggest is to search reversely
ie: create a loop search the tables in the syscomments
. The below stored procedure may help
CREATE PROCEDURE dbo.sp_getObjects

Here is an example to find list of tables used in a procedure
;WITH procs
AS
(
SELECT o1.name AS proc_name,
o2.name AS table_name,
ROW_NUMBER() OVER(PARTITION BY o1.name,o2.name ORDER BY o1.name,o2.name) AS row
FROM sysdepends d
INNER JOIN sysobjects o1
ON o1.id=d.id
INNER JOIN sysobjects o2
ON o2.id=d.depid
WHERE o1.xtype = 'P'
--AND o2.name = 'tabname1' OR o2.name = 'tblname2'
)
SELECT proc_name, table_name
FROM procs
WHERE row = 1
ORDER BY proc_name, table_name
Also, this query returns all the table names of all dependent tables in a Stored procedure.
SELECT DISTINCT o.id, o.name as 'Procedure_Name' , oo.name as 'Table_Name'
FROM sysdepends d, sysobjects o, sysobjects oo
WHERE o.id=d.id
and oo.id=d.depid and depnumber=1
ORDER BY o.name,oo.name
KyleMit's answer is using a table that will be deprecated soon as well. It is recommended to use sys.sql_experssion_dependencies instead of sys.sql_dependencies, e.g.,
SELECT DISTINCT p.name AS proc_name, t.name AS table_name
FROM sys.sql_expression_dependencies d
INNER JOIN sys.procedures p ON p.object_id = d.referencing_id
INNER JOIN sys.tables t ON t.object_id = d.referenced_id
ORDER BY proc_name, table_name
This should work with SQL Server 2008+.
