Searching Stored Procedures & User Defined Functions
-
I would like to be able to search through my stored procedures and functions to find specific text.
For example, I need to find which stored procedures call certain functions, or other stored procedures.
Thank you very much.

If you don't have Stored Procedures that exceed 4,000 characters, this will work
SELECT
*
FROM
INFORMATION_SCHEMA.ROUTINES
WHERE
ROUTINE_DEFINITION LIKE '%mail%'
That way, you get a list, you can subsequently work on. However, if you do have longer procedures and depending on the number of expected procedures to change, script them out, use a texteditor of your choice and then reapply them to the server.

There are a few utilities as well that can help here. We had a press release about SQL Digger last week, which does searching.

Frank,
This works awesome for the Stored Procedures. Thanks!
Is there a table for the User defined Functions like "INFORMATION_SCHEMA.ROUTINES"?

INFORMATION_SCHEMA.ROUTINES includes SPS and Functions (all 3 types).

No, for UDF's you need to query directly the system tables. I'm a bit short now, since I have a meeting right now and am already late. Search the script section here. Should bring up some good stuff.

You can run this script to see for yourself :
if object_id('TestMyTheory') > 0
drop function TestMyTheory
GO
CREATE Function dbo.TestMyTheory()
RETURNS INT
AS
BEGIN
RETURN 1
END
GO
SELECT
Routine_Name, Routine_Type, Routine_Definition
FROM
INFORMATION_SCHEMA.ROUTINES
WHERE
ROUTINE_DEFINITION LIKE '%TestMyTheory()%'
GO
drop function TestMyTheory
GO

Yes, seems to work fine for searching udf's!

Haha, Remi, thanks for correcting my on this. This shows how much I deal with UDF's.

There's some pretty good posts here that already work, but I thought I'd throw in my 2 cents... this is what I use and it will find "whatever" in all stored procs, views, UDF's, and whatever else that lives in the Comments system table. Returns the name and type of object "whatever" is found in. It does have the minor danger of not finding something if it straddles the 4k border in code, but, for me, that's usually an acceptable risk because a "whatever" is many times mentioned more than once in the code I've been working with.
--Find name of proc, view, function, etc containing text in DDL
SELECT DISTINCT so.Name, so.Xtype
FROM SYSOBJECTS so,
SYSCOMMENTS sc
WHERE so.ID = sc.ID
AND sc.Text LIKE '%whatever%'
ORDER BY so.xtype,so.Name

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.Change is inevitable... Change for the better is not.

Deterministic udf aren't so bad to use Frank... but I'd agree that some function uses can be devastating on performance.

Not only that...
You can frequently observe the question why one cannot use GETDATE() inside a UDF. And equally frequent you will see someone suggesting to wrap GETDATE() inside a view and call this view inside the UDF. Now, consider this:
USE northwind
GO
CREATE VIEW foolview
AS
SELECT
GETDATE() AS Jetzt
GO
CREATE FUNCTION fool_me()
RETURNS DATETIME
AS
BEGIN
RETURN (
SELECT
Jetzt
FROM
foolview
 
END
GO
CREATE function you_dont_fool_me(@Jetzt datetime)
RETURNS DATETIME
AS
BEGIN
RETURN @Jetzt
END
GO
DECLARE @Jetzt datetime
SET @Jetzt = GETDATE()
--Test 1 viele Zeilen
SELECT DISTINCT
dbo.fool_me()
FROM
[Order Details] AS od
INNER JOIN
Orders AS o
ON
o.OrderId = od.OrderID
--Test2 eine Zeile
SELECT DISTINCT
dbo.you_dont_fool_me(@Jetzt)
FROM
[Order Details] AS od
INNER JOIN
Orders AS o
ON
o.OrderId = od.OrderID
GO
DROP FUNCTION fool_me
DROP FUNCTION you_dont_fool_me
DROP VIEW foolview

Not only does this prove that statement wrong, but it also shows that such scalar UDF's are calculated on a row-by-row basis. As you've mentioned, performance-killers.

Yes this is prtty much what you had posted a few weeks back... that's what made me realize how much of a killer it can be.

A while ago I posted Strored Procedure for this kind of searches.
