I'm trying to display the progress of a stored procedure that is called from C# app code and running in SQL Server 2005.  Is it possible to track how much of the said stored procedure is complete, doesn't have to be exact, just estimated?  I have the stored procedure code below and it is used to completely delete all data from a database and usually takes betwee 4 and 10 minutes to run depending upon how much data is in it.
USE [myDB]
GO
 
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
 
CREATE PROCEDURE [dbo].[sbs_ClearAllData]
 
AS
BEGIN
 
	SET NOCOUNT ON;	
 
	-- Clear out tables
	EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
	EXEC sp_MSForEachTable  
	'IF OBJECTPROPERTY(object_id("?"), "TableHasForeignRef") = 1  
		DELETE FROM ?  
	else   
		TRUNCATE TABLE ?'
	EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
	EXEC sp_MSForEachTable  
	'IF OBJECTPROPERTY(object_id("?"), "TableHasIdentity") = 1   
	DBCC CHECKIDENT ("?", RESEED, 0)'
 
	-- Populate a couple of the tables.
	INSERT INTO myTable1
		(Id, Code, Description, IsCredit)
	VALUES
		(NEWID(), 'D', 'Debit', 0)
	INSERT INTO myTable2
		(Id, Code, Description, IsCredit)
	VALUES
		(NEWID(), 'C', 'Credit', 1)
 
END

you can try querying the no of entries on myTable1 and  myTable2 (Make sure you put  'NOLOCK' hints ) ,

Hello bakerOSU333,

You could set up a MSMQ and try to have the stored procedure post a message into that queue, but you are using other stored procedured, so could be difficult.

Have a look at books on line for :

CREATE MESSAGE TYPE message_type_name
    [ AUTHORIZATION owner_name ]
    [ VALIDATION = {  NONE
                    | EMPTY
                          | WELL_FORMED_XML
                    | VALID_XML WITH SCHEMA COLLECTION
                                                    schema_collection_name
                   } ]
[ ; ]



Regards,

And, probably easier to create another thread and query the tables as aneesh has said.... You will know how many have gone, but not how many yet to do... Might need to do a count first.

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

Yeah it was a bit cryptic.  Let's try that again:
>>Is it possible to track how much of the said stored procedure is complete, doesn't have to be exact, just estimated? <<
You cannot get any feedback from a running Stored Procedure.  The best you can do as suggested is calculate the number of rows affected before executing the Stored Procedure and estimate the time it will take.  But then you are, what could be called in the realm of the Heisenberg uncertainty principle.

Another method, which may (not) work is to record the amount of time it takes to execute in a procedure performance table.  Then do an estimate of time remaining based upon average execution time.

First off, thanks for all the input.  Let me run this idea by you guys... So how could alter that stored procedure to do the following:  (1) before running the procedure, what command could I pass to SQL to the total count of user tables in the database?  (2) then how would I alter the stored procedure I have above to just delete the data one table at a time?  (then I could use my progress bar to just loop through all the tables and it may lag in some of the bigger tables, but it would be good enough for my stuff)  Also, I still want to be able to delete all the data, regardless of foreign keys and such, but keep the schema and integrity...
