How can i get the list of tables in the stored procedure

Question

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% not give the

Answer 1

The two highest voted answers use a lot of deprecated tables that should be avoided.
Here's a much cleaner way to do it.

Get all the tables on which a stored procedure depends:

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+

List of Changes:

• sysdepends should be replaced with sys.sql_dependencies
  • The new table uses object_id instead of id
  • The new table uses referenced_major_id instead of depid
• Using sysobjects should be replaced with more focused system catalog views
  • As marc_s pointed out, instead use sys.tables and sys.procedures
  • Note: This prevents having to check where 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!

  • In fact, SQL is smart enough to use DISTINCT behind the scenes.

  • 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
    

Answer 2

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
            )

This code recursively looks at every Stored Procedure in your Stored Procedure and gives you the full list of all tables used.

Answer 4

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
(
    @ObjName VARCHAR(255)
)
AS
BEGIN
    SET NOCOUNT ON
    DECLARE @Idkeyst INTEGER
    DECLARE @Idkeyed INTEGER
    DECLARE @tblName VARCHAR(255)
    DECLARE @Objects VARCHAR(MAX)
    IF NOT EXISTS(SELECT 1 FROM sys.objects where NAME = @ObjName AND type in ('P', 'FN','TR'))
    BEGIN
        PRINT 'NO Text Available for the Parameter'
        RETURN(0)
    END
    CREATE TABLE #ProcStr
    (
        Idkey       INT IDENTITY(1,1),
        ScriptStr   VARCHAR(MAX)
    )
    CREATE TABLE #Depends
    (
        Idkey           INT IDENTITY(1,1),
        Depends         VARCHAR(255)
    )
    CREATE TABLE #Objects
    (
        Idkey           INT IDENTITY(1,1),
        ObjectName      VARCHAR(255)
    )
    INSERT INTO #ProcStr
    (ScriptStr)
    EXEC sp_helptext @ObjName
    DELETE #ProcStr WHERE LTRIM(ScriptStr) LIKE '--%'
    DELETE #ProcStr WHERE LTRIM(REPLACE(ScriptStr,CHAR(9),'')) LIKE '--%'

    SET @Idkeyst = 0
    SET @Idkeyed = 0
    WHILE 1=1
    BEGIN
        SELECT @Idkeyst = MIN(idKey) FROM #ProcStr WHERE ScriptStr like '%/*%' and Idkey > @Idkeyst
        IF @Idkeyst IS NULL
            BREAK
        SELECT @Idkeyed = MIN(idKey) FROM #ProcStr WHERE ScriptStr like '%*/%' and Idkey >= @Idkeyst
        DELETE #ProcStr WHERE Idkey >= @Idkeyst and Idkey <=@Idkeyed
    END
    DELETE #ProcStr WHERE ISNULL(LTRIM(REPLACE(ScriptStr,CHAR(9),'')),'')=''    
    INSERT INTO #Depends
    (Depends)
    SELECT DISTINCT t.name 
    FROM sys.sql_dependencies d

    INNER JOIN sys.tables     t ON t.object_id = d.referenced_major_id
    where p.name = @ObjName

    INSERT INTO #Objects
    SELECT name from sys.objects o WHERE Type = 'U' AND NOT EXISTS
    (SELECT 1 FROM #Depends WHERE Depends = o.name)

    SET @Objects = ''
    SELECT @Objects = CASE WHEN ISNULL(@Objects,'') = '' THEN '' ELSE @Objects+', ' END+ Depends
    FROM #Depends

    UPDATE #ProcStr
    SET ScriptStr = LTRIM(RTRIM(ScriptStr))
    UPDATE #ProcStr
    SET ScriptStr = REPLACE(ScriptStr,CHAR(9),'')
    UPDATE #ProcStr
    SET ScriptStr = REPLACE(ScriptStr,CHAR(13),'')
    UPDATE #ProcStr
    SET ScriptStr = REPLACE(ScriptStr,CHAR(10),'')
    SET @tblName = ''
    SET @Idkeyst = 0
    WHILE 1=1
    BEGIN
        SELECT @Idkeyst = MIN(idKey) FROM #Objects WHERE Idkey > @Idkeyst

Answer 5

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

Answer 6

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+.
