How to see progress of running SQL stored procedures?

Question

Consider the following stored procedure..

CREATE PROCEDURE SlowCleanUp (@MaxDate DATETIME)
AS
BEGIN
    PRINT \'Deleting old data Part 1/3...\'
    DELETE FR         


        

Answer 1

Yes you should be able to get the message to print immediately if you use RAISERROR:

RAISERROR('Hello',10,1) WITH NOWAIT

Answer 2

I have found a great NON-INTRUSIVE way to see the progress of along running stored procedure. Using code I found on Stackoverflow of SP_WHO2, you can see the first column has the current code actually being run from the PROC. Each time you re-run this SP_Who2 process, it will display the code running at the time.This will let u know how far along your proc is at anytime. Here is the sp_who2 code which I modified to make it easier to track progress:

Declare @loginame sysname = null
DECLARE @whotbl TABLE 
    ( 
      SPID        INT    NULL 
     ,Status    VARCHAR(50)    NULL 
     ,Login        SYSNAME    NULL 
     ,HostName    SYSNAME    NULL 
     ,BlkBy        VARCHAR(5)    NULL 
     ,DBName    SYSNAME    NULL 
     ,Command    VARCHAR(1000)    NULL 
     ,CPUTime    INT    NULL 
     ,DiskIO    INT    NULL 
     ,LastBatch VARCHAR(50)    NULL 
     ,ProgramName VARCHAR(200)    NULL 
     ,SPID2        INT    NULL 
     ,RequestID INT    NULL 
     ) 
    INSERT INTO @whotbl 
     EXEC sp_who2  @loginame = @loginame 

    SELECT CommandText = sql.text ,
           W.*  
          ,ExecutionPlan   = pln.query_plan 
          ,ObjectName  = so.name  
          ,der.percent_complete 
          ,der.estimated_completion_time 
          --,CommandType =der.command 
      FROM @whotbl  W 
 LEFT JOIN sys.dm_exec_requests der 
        ON der.session_id = w.SPID 
       OUTER APPLY SYS.dm_exec_sql_text (der.sql_handle) Sql 
       OUTER APPLY sys.dm_exec_query_plan (der.plan_handle) pln 
 LEFT JOIN sys.objects so 

I wish I remember who I got this original code from, but it has been VERY helpful. It also identifies the SPID if I need to kill a process.

If you use RAISERROR with a severity of 10 or less, and use the NOWAIT option, it will send an informational message to the client immediately:

RAISERROR ('Deleting old data Part 1/3' , 0, 1) WITH NOWAIT
