Not Waiting For A Stored Procedure To Finish
May 7, 2008
I have a Stored Procedure which Ideally should run when a Customer Logs in, the Procedure will check the available stock and create a Temp Table for the Information, which allows many other Queries in the site to run a lot faster, (due to no joins). The Query has taken as much as 30seconds (Lots of Records and 1/2 dozen Joins) to run upon log in and causing a Timeout for the web application.
I want the procedure to run as it is, but for the login method to not be dependent on the Process tried this in .NET cmd.BeginExecuteNonQuery() (cmd=SQLCOmmand)
which doesn't do what I want it just allows me to run heaps of QUeries at the same time.
Can anyone help me with getting this procedure to run and not hold up the Web application? Not sure whether I need to do this in .NET, or whether I can get .NET to run a Batch File or something, but someone must have had a similiar problem, please help.

Hi!
I hope to get some help with a stored procedure that never stops executing when run from Reporting Services development environment.
The server: SQL Server 2005 SP2 x86, 2 gig ram, 2 processor cores.
The stored procedure I execute is simple, it declares and sets some variables and then a executes a select statement
with 6 joins.
If I execute the stored procedure from Management Studio the query runs and returns about 50 000 rows in ~2 seconds. No problems!
The problems arises when I execute the stored procedure from visual studio (testing my reporting services report). The query will never complete its execution!?
I checked the activity monitor and can verify I have NO processses with any information in the blocked by or blocking column.
The strange thing is I got 3 rows for process id 64, only one row (row 1) printing the executing user.
Row 1: Stutus suspenden, Wait Type CXPACKET
Row 2 and 3 are pending between runnable and suspended and wait typoe pageiolatch_ex and no wait type at all when I refresh. These are probably parallell threads executed in the query.
The strange thing here is that this process never completes and if I do a trace the last command executed is select statement. I donīt understand what the problem is, sql server bug? Parellelism problem (in this case, why?)
Any help is appreciated
Regards

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Hi all,
I have 2 sets of sql code in my SQL Server Management Stidio Express (SSMSE):
(1) /////--spTopSixAnalytes.sql--///
USE ssmsExpressDB
GO
CREATE Procedure [dbo].[spTopSixAnalytes]
AS
SET ROWCOUNT 6
SELECT Labtests.Result AS TopSixAnalytes, LabTests.Unit, LabTests.AnalyteName
FROM LabTests
ORDER BY LabTests.Result DESC
GO
(2) /////--spTopSixAnalytesEXEC.sql--//////////////
USE ssmsExpressDB
GO
EXEC spTopSixAnalytes
GO
I executed them and got the following results in SSMSE:
TopSixAnalytes Unit AnalyteName
1 222.10 ug/Kg Acetone
2 220.30 ug/Kg Acetone
3 211.90 ug/Kg Acetone
4 140.30 ug/L Acetone
5 120.70 ug/L Acetone
6 90.70 ug/L Acetone
/////////////////////////////////////////////////////////////////////////////////////////////
Now, I try to use this Stored Procedure in my ADO.NET-VB 2005 Express programming:
//////////////////--spTopSixAnalytes.vb--///////////
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sqlConnection As SqlConnection = New SqlConnection("Data Source = .SQLEXPRESS; Integrated Security = SSPI; Initial Catalog = ssmsExpressDB;")
Dim sqlDataAdapter As SqlDataAdapter = New SqlDataAdaptor("[spTopSixAnalytes]", sqlConnection)
sqlDataAdapter.SelectCommand.Command.Type = CommandType.StoredProcedure
'Pass the name of the DataSet through the overloaded contructor
'of the DataSet class.
Dim dataSet As DataSet ("ssmsExpressDB")
sqlConnection.Open()
sqlDataAdapter.Fill(DataSet)
sqlConnection.Close()
End Sub
End Class
///////////////////////////////////////////////////////////////////////////////////////////
I executed the above code and I got the following 4 errors:
Error #1: Type 'SqlConnection' is not defined (in Form1.vb)
Error #2: Type 'SqlDataAdapter' is not defined (in Form1.vb)
Error #3: Array bounds cannot appear in type specifiers (in Form1.vb)
Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)
Please help and advise.
Thanks in advance,
Scott Chang
More Information for you to know:
I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly.
I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete]
@QQ_YYYY char(7),
@YYYYQQ char(8)
AS
begin
SET NOCOUNT ON;
select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],
[Code] ....

I have a sub that passes values from my form to my stored procedure. The stored procedure passes back an @@IDENTITY but I'm not sure how to grab that in my asp page and then pass that to my next called procedure from my aspx page.

I am having a problem importing data into SQL 7 from any type of source. I go through the whole import process no problem. When I click the finish button to start the import, nothing at all happens. Enterprise Manager and the DTS just hang and I must use crtl+alt+delete to end the program. Can anyone give me any suggestions as to what might be happening. Big Thanks in advance, I've been working on this for days.

I am a VoIP phone system using SQL on the back end. I am trying to get a Trigger to fire and email me when a certain number has been dialed.
Create Trigger trg_Emergency_Calls on dbo.CallDetailRecord for Insert
IF @@ROWCOUNT=0 RETURN ---NO rows affected exit proc
IF (SELECT finalcalledpartynumber FROM inserted)='95593684' BEGIN
--RAISERROR ('Call Stored Procedure Here',16,10)
EXEC WEB_SRVR03.master.dbo.sp_SMTPMail @body='This is a test Email'
END
Return
GO
The problem is I have to execute the actually email SP is on another server and has to be that way. The trigger actually runs each time but if the IF statement becomes true then the trigger hangs and never completes. Watching the other server(WEB_SRVR03) there is never a request to execute the sp_SMTPMail. I have been trying to troubleshoot this with profiler but I never see any locks or anything that would give me a problem. Also the insert statement that caused the trigger to fire also never finishes and so the record isn't written to the db. If anyone has any suggestions I would appreciate it.
Thanks

I want to finsih the execution of a DTS package from an ActiveX task. If a condition is ok, the package would continue as normal. If not, I want to finish the package without any error. Just without executing the next tasks. Do you have any idea?

Hi,
I have a package that calls an "Execute Process" task which calls a .bat file. The .bat file references a mapped drive, as in:
s:
cd s:mypathftp
type %1 | c:gnupggpg --yes --batch --logger-fd 1 --passphrase-fd 0 --decrypt-files %2 > logsautodecrypt.log
Everything runs fine in BIDS, however from the job the .bat file portion just hangs forever.
Any ideas?
Thanks

We are having a problem with an SSIS package. The package gets stuck when it runs a data flow component that reads data from 5 large tables, performs a union on the data, does a conversion on one field and then writes the data to another table. This all happens in the same database and the ssis package runs on the same server as the database.
When I look at the waiting tasks on the sql server I always see the following type of scenario. It is always the ASYNC_NETWORK_IO that is causing the others to wait.
SPID
Wait type
duration
Waiting Address
Blocking Address
118
ASYNC_NETWORK_IO
47
0x0000000000C2FD68
NULL
118
CXPACKET
47
0x0000000000C2F2E8
0x0000000000C2FD68
118
CXPACKET
47
0x0000000000EB4DA8
0x0000000000C2FD68
118
CXPACKET
47
0x0000000000ECB048
0x0000000000C2FD68
118
CXPACKET
47
0x0000000000EE12E8
0x0000000000C2FD68
In some cases the duration column goes up to several hours until we finally just kill the package. At the same time, we also see that session 118 is consuming very large amounts of memory (in sys.dm_exec_query_memory_grants). However, when we look at the dtexec process that is running the package on the server it only has a working set of about 100Mb. We've tried rewriting the dataflow task as a simple stored procedure and this goes through smoothly.
Can anyone shed some light on what is going on and how to avoid this type of locking situation (other than just using plain old T-SQL).

I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.
How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?
Thanks in advance

Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

I have a scheduled job to run daily at 4 am. the job imports data from client side from text
files and puts data in our sql table.It takes around 1 hour.
the problem is it doesnt stops after the import process completes.so after one hour
i can see the data is imported into my sql table so thats fine but the job keeps running.
I tried observing that job's spid in activity monitor in sql 2005 but after one hour i cant even see
that spid but still job runs. its weird.and after that when i stop the job manually then it stops
saying job completed succcessfully.
that step is a last step and it uses windows cmd.my understanding is the job step doesnt
understands that it got finished. what should i do in here?? any ideas r appreciated
we are running the same job for another servers and its fine.

No Error but Export to Excel does not finish
When the report has 2 pages with total 500 rows exporting to Excel is not a problem.
If it has 100 pages 5000 rows exporting to excel does not end and it does not return any error but the process does not end either. What might the problem be?

I have been working with this for about a month now, and no similar problems to date. Today I am trying to introduce 4 configuration flags that control whether optional ETL stage feeds are executed. I did this by adding a do-nothing script component. The precedent and constraint is used, and it checks the boolean variable flag. The first package executes fine. But it never returns from there. This precedent has nothing fancy on it either. It simply does not run any more of the package, make any more conditional checks, nor the common completion tasks. It just seems to think it is done.
The optionals all fire execute package tasks. One thing that might be tripping it up is that I attempt to run one package twice, each time with varying parent package variable set to control it to use a different destination database for each run. Should this not be OK to do?
Any hints would be greatly appreciated.

We recently upgraded out SQL version from SQL2008R2 to SQL2014. As such, the compatibility mode changed to SQL2104 (120).
We have several queries that used to run fine that now take forever to bring back results. There are no errors (which surprised me). They just take way too long now. PLus they seem to be causing high I/O and CPU.
If I change the compt level back to SQL2008 - these queries run fine.
QUERY with SQL2008 compt level - finished in 2 minutes.
QUERY with SQL2014 compt level - finishes in 3 hours 22 minutes.
same exact query - same server - only thing changed was compatibility level.
WHat do I look for in the queries that could be causing this? (they look fine but obviously I'm missing something here)..

Hi,
I've setup the option to mail the error to a person. When the option is on I get the error message by mail but the package does not finish (eg. the failing task does not become red and the output windows never says anything about the error) - if I set the option to off the task fails as expected.
Is there something I havn't set up correctly?

Hi all,
I am trying to debug stored procedure using visual studio. I right click on connection and checked 'Allow SQL/CLR debugging' .. the store procedure is not local and is on sql server.
Whenever I tried to right click stored procedure and select step into store procedure> i get following error
"User 'Unknown user' could not execute stored procedure 'master.dbo.sp_enable_sql_debug' on SQL server XXXXX. Click Help for more information"
I am not sure what needs to be done on sql server side
We tried to search for sp_enable_sql_debug but I could not find this stored procedure under master.
Some web page I came accross says that "I must have an administratorial rights to debug" but I am not sure what does that mean?
Please advise..
Thank You

We have a two node cluster running W2K and SQL2000. The agent starts, but we cannot access any of the jobs. It gives us the 14258 Agent is starting, try again later... error message. We know that this is not the case, we have waited several hours without it "starting". The SQL Agent log indicates that the agent is waiting on SQL Server to recover databases, but all of our databases are up. It is almost as if during startup a flag did not get set to indicate that a database was recovered.
Has anyone run across this before? If so, did you ever figure out how to fix it?

I have this query I need for a report. Originally it was 4 queries to be used in Crystal Reports. Now I want to create the same report with SSRS and therefore I incorporated all queries in one in order not to use subreports [URL].....
Tempdb fills up to nearly 90 GB. I am running SQL Server on a local box, so I am sure there is no other traffic. Here is the query:
SELECT AdHaupt.NSprache_ID
,AdHaupt.mengentext AS mengentextHaupt
,AdHaupt.Einzelpreis
,AdHaupt.Anzeigebezeichnung
,AdHaupt.Gesamtpreis
[Code] ...
I ran it with TOP 10 as well, just to see if it will finish at all, but it never did (ran for an hour now).

Is anyone have already encountered such a problem :
When a table is locked by several locks (key, pag), either a SELECT request which does not need to lock any row cannot succeed.
In SQL Server Enterprise Manager, I see that my request is waiting for a lock "LCK_M_S" !!!
How I can avoid this kind of situation which seems to me completely abnormal.
I have never been faced with this kind of problem in Oracle.
Thanks for anyone who will help me to resolve this "bug".

I'm wondering if there is any way for me to execute any type of command (delete, insert, create, alter, etc) on management studio without having to wait the server answer.
On Oracle, I use DBMS_JOB. On SQL Server, do I have to create a SQL SERVER Agent Job? What if I don't have permission to create that kind of jobs?
