Fire And Forget Messages
Sep 4, 2006
I am designing an application using service broker, and to increase performance of the application, sometimes I will be sending messages without waiting for a reply. After reading the article by Remus at http://blogs.msdn.com/remusrusanu/archive/2006/04/06/570578.aspx regarding fire and forget messages I realised I should always let the target end the conversation first so I can catch any errors. However, other times when i send a message from the initiator queue, I will want to wait for a reply.
If I have an activated stored procedure attached to the initator queue (as suggested in the article) would it mean that I would not be able to handly ANY replies manually (ie from the code that originally started the conversation).
If this is the case, should I have two initiating queues, one that handles fire and forget type requests and another where it waits for a reply, or should I just have some sort of clean up routine scheduled which checks for error replies and ends any other conversations that have been ended by the target?

Hi there .NET community.
I was wondering if there was a way to launch a stored procedure froman aspx page without the sqlCommand object sitting waiting for the sproc to return something.The procedure takes about 10 minutes to execute and the page timeouts.Is there a way to just execute the procedure and procede to the next line of script?
Thanks.

How can I execute a long running transaction using something similar to the fire and forget pattern?
I intend to start the execution of a very long stored proc from within IIS. I would like to execute a sql script that will start the job and return immediately so that it doesn't hold an IIS thread.

I create a connection to an OLE db source and use SQL Server authorization and save the password, the connection manager seems to "forget" the password. That is, when I click the 'save password' check box, and do a test connection, it connects fine. But as soon as I close that connection window, and reopen it, the password box is empty, and the 'save password' box is still checked.Â
While using the connection manager name in the SSIS component (say script task) the connection is failing . As a workaround, the whole connection string has been put in a variable and used that variable in the SCRIPT task.
Is it a bug or some other property need to be set to use ConnectionManager Name .

Hello, please help!!
I have spent days searching the web and forums for an answer to this simple question and cannot find an example.
I have built a service broker application on sql server 2005. The application puts some xml on an incoming queue which is basically a few parameters to be used in a query. This queue will then call a stored proc which does some business logic and puts the resulting results in another queue also in xml.
I have written a test harness in SQL to put messages on the inbound queue and then some sql to retrieve the returned code from the outbound queue.
What I want to do is be able to convert the SQL which does this into .net code to be used by an application. i.e. write in .net some code to put xml on a queue and then write some .net code to retrieve xml from another queue.
I wouldn't have thought this would be a difficult thing to do and would have been done hundreds of times, but unable to find anything to simply send and retrieve XML to service broker queues....
thanks for your help.. its really needed. I found some links, but they are really vague and often doing select statments in service broker or something like this. I don't want to call any sql, just send and recieve XML on the queues.
any example code that does this, would be really helpfull
kind regards,

Is it possible to create a trigger to monitor when a value changes from 1 to 0 in a particular row.
Example, rows have names, pins and status columns. When the status column of a row changes from 1 to 0, I am going to send a mail item to the person whose name has had the status changed.

Hello,
I have a SQL Server 2000 DTS package in which the first step executes a batch file. The batch file contains FTP commands that log into an FTP server, and pull down whatever file is there.
I set up a failure workflow to send an email if the step fails. When I have a SQL Server job run this package, and there is no file to dowload, the whole package fails without the failure workflow result firing.
For the step (DTSStep_DTSCreateProcessTask_1), I have the 'FailPackageOnError' property set to -1. In the package properties, I have the check box for 'Fail Package on First Error' cleared.
What do I need to do so that the failure workflow occurs when the step fails?
Thank you for your help!

After many problems with permissions I have got got SQL to accept a notification request but the public static void OnChange(object sender, SqlNotificationEventArgs e) is never triggered. The notification registers and de-registers ok. The same connect string successfuly connects to the same database to process queries.
I can see the GUID suffixed stored procedure, queue and service being created. Where does SQL2005 store the address/name of the routine it is to trigger? (When the notification is cancelled, the guid-siffixed items disappear) I have looked at the generated stored procedure, queue and service, but there is no indication of what is to be called back.
I have followed the instructions at http://msdn2.microsoft.com/en-us/library/ms181122.aspx, but so far without avail. I have checked the Application and system event logs, but there is indication therein. Also the SQL log.
So my questions are:
1) Where is the callback stored (is it a pointer or an actual name) ?
2) What steps should I take to resolve this?

I am using SQL Server 2005 database for a webbased application built on .net 2.0. Here is my situation. I have a SubmitDate and a Status field in a table. I want the trigger to fire based on the datevalue in the SubmitDate field. SubmitDate field is the last date for the user to submit an application. For eg: if the SubmitDate value is 03/10/07 , I want the trigger to fire on :01 of 03/11/07 to change the Status field value to Inactive. Is that possible? Thoughts on how to do it?

Hi
In the page load of my webpage I call a databind for a gridview.
It generally calls this event handler :
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
However sometimes (seemingly randomly) it doesn't.
Any ideas?
Thanks
p
protected void Page_Load(object sender, EventArgs e)
{
...
if (searchText != "")
SqlDataSource1.SelectParameters["search"].DefaultValue = searchText;
else{
SqlDataSource1.SelectParameters["search"].DefaultValue = "";
GridView1.DataBind();
}

DECLARE @ITIDint
SELECT @ITID = (SELECT ITid

Is there a way to make a sql table trigger fire off conditionally on calling app?We have this vendor app database which also have in-house custom built app operates on them. Some one are thinking using triggers to audit second part of the app activities, but want to skip the vendor app part of operation for at least performance reason.To my knowledge, the answer is no. An insert trigger will fire off whenever there is an insert. It doesn't provide a mechanism to check which app/process first, then conditionally fire or not fire.

Hi to all Gurus,I am working with two tables, where in if a record is inserted in onetable an insert trigger fires and inserts relevant information for thatrecord in the second table.

Any help is greatly appreciated.--Part-time BE

I have a trigger on UPDATE on a table. I'm running some maintenanceUPDATE and DELETE queries which I want the trigger to ignore but at thesame time I want other UPDATE queries that other users might be runningto keep triggering the trigger. Is there a SET statement perhaps thatI could set before my query? Or a clause in the UPDATE statement?This is on MSSQL 2000 server, on Win2k3

I have a package which have two sequence container, first container is used to transfer data to a staging area and second sequence container is used to transfer to destination from that staging area. And I also apply transaction required to second sequence container.
There are several execute sql tasks and several data flow tasks inside two sequence container.
first sequence container( 1.execution sql task-> 2.data flow ->3.execution sql task) ->
second sequence container(4.execution sql task-> 5.execution sql task-> 6.data flow-> 7.data flow -> 8.execution sql task-> 9.data flow...)
I create ExecutionLog table which is used to log status for this package on our sql server. First this status field is null, then during this package run , it change to 'in process', and after this package finished, it change to 'success' or 'failure' depending this package can run successfully or not.
This package can be run only if status is 'success' ,'failure' or null. So I need to change this status field during package execution.
For updating package to failure, I need to add event handler to change that status using execute sql task.
First time I perform to execute sql task on onError event handler tab (this event handler is applyed on package level ) .
And for testing envent handler I use old schema version to make sure I get failure for '8 execution sql task'.
But package seems to get stuck at '8 execution sql task' inside second sequence container( always yellow when I run from ssis) and never fire envent handler. '8 execution sql task' is used to update related table.
Second time I remove onError envent handler and change to use on onTaskFailed event handler tab (this event handler is applyed on package level ) .
But everything is the same as using onError event handler except I got error output but still can not fire event.
Why '8.execution sql task' can not fire onError or onTaskFailed?
For this case what kind of event handler I need to use, what kind of level I need to apply for this event handler.

As I understand it, a subscription has a SQL Agent job which fires and inserts a row into the ReportServer.dbo.Event table. Then the SSRS windows service polls for these and picks them up and runs the subscriptions.
What I'm trying to do is to prevent subscriptions from executing during a 6 hour window every day. End users may define a schedule that runs during that 6 hour window. If they do, it should run those subscriptions as soon as we complete the 6 hour window.
I thought about pausing the schedule, but I'm afraid that when you resume the schedule, it won't catch up if it was supposed to run during the 6 hour window.
So I'm thinking the best idea is to let the SQL Agent job continue to fire and insert rows into the ReportServer.dbo.Event table... but I need some way to prevent the windows service from picking up those events until we've passed the 6 hour window. How can I do this?
Thanks in advance.

Hello all,
We have encountered a weird problem; we have an application that registers to several queries for notification.
For several weeks everything worked fine, any change to any query result in the database triggered the notification event, but since yesterday the mystery began€¦ since yesterday not all changes triggers events , changing one table raise the notification event, changing the other doesn€™t , all seems fine in the database , the application reports that all queries were registered successfully , in the subscription view in the database we can see that all the queries that the application subscribed to are present€¦
What can be the problem? Is it something in the database? Can it be a problem in our application, please keep in mind that everything worked until yesterday€¦
Thanks,
Eden

A job runs every morning at 3.00 am to back up a database. Many of the tables have triggers on to write updates, deletes and inserts to audit tables.A typical trigger looks like this.
USE [ProjectDB_Live]
GO
/****** Object: Trigger [dbo].[trgStakeHolders] Script Date: 03/02/2015 10:23:38 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[code]....
I added a trigger to a table over the weekend - structured the same as the one above and, when the back up ran last night, it copied every row in the table into the audit table as if every row in the table had been updated.

Does anyone know how to do the following. I'm trying to mimicreplication with triggers.I have 2 databases, each have these 2 tables.1.USERSID intNAME varchar(20)2.CHANGESTABLE varchar(20)TYPE varchar(10)col1 varchar(20)col2 varchar(20)On the USERS table I have a for insert trigger. Whenever a new user isadded the trigger puts an entry into the CHANGES table such as("USERS", "INSERT", "1", "Fred")I now have an application (vb.net) that monitors the CHANGES table onserver1. If it finds an entry it determines the table using the TABLEcolumn and performs the necessary insert and deletes the entry fromCHANGES. Now the problem is server2 also has an for insert trigger onthe USERS table so it puts an entry into CHANGES on server2. As youcan imagine this goes around in a loop.What I was hoping for was someway of saying, "I'm inserting from myapplication so don't do the trigger".Any ideas gratefully appreciated.Steve.

Hi.I need to make a trigger which fires when after an UPDATE is done ontable A in database X. The trigger must perform a statement whichcopies some of the data from the update to table B in database Y onthe same server.My question is: Can I access the data which caused the trigger to fireor just get an indication of which entry in table A had been updated?Best RegardsJens Christian Andersen.
