I was wondering when events inside IDTSComponentEvents interface are called when you throw a SSIS package? I've got a private class which implements IDTSEvents and along with that got another one that implements the IDTSComponentEvents. I see how neither of them are fired when I debug the code by using F11, and I don't know what is it for.
Let me know your comments or come back to me if you need further details on that.
Is it possible to only handle the outter-most event? For example, I have an email that goes out in response to OnPreExecute and OnPostExecute, but I only want it to go out once, instead of for every tasks/object.
I am investigating using Query Notifications - a great addition BTW. I have built a test app - loosely based on MSDN example - and am running against a SQL Express 2005 server. I have the following problem:
I have start/stop buttons to enable change checking, and a hardcode query that I am using for testing. If I stop and restart I now recieve duplicate notifcations, a single change causing the OnChange event to fires twice with two different ids Repeat this and the event will fires 3 times for each change and so on.
This only happens with a running app, if I restart the app I only get a single notification so I assume I have missed a step in stopping query notifcations or reinitialisation. I have include code below:
private bool Start()
{
try
{
// Remove any existing dependency connection, then create a new one.
SqlDependency.Stop(_currentConnectionString);
if (SqlDependency.Start(_currentConnectionString))
{
if (connection == null)
{
connection = new SqlConnection(_currentConnectionString);
}
if (command == null)
{
command = new SqlCommand(_sqlQueryString, connection);
}
return (true);
}
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
return false;
}
private void Stop()
{
SqlDependency.Stop(_currentConnectionString);
if (command != null)
{
command.Notification = null;
command = null;
}
if (connection != null)
{
connection.Close();
connection = null;
}
}
private void GetDataSnapshot()
{
// Empty the dataset so that there is only
// one batch of data displayed.
dataToWatch.Clear();
// Make sure the command object does not already have
// a notification object associated with it.
command.Notification = null;
// Create and bind the SqlDependency object
// to the command object.
SqlDependency dependency = new SqlDependency(command);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
using (SqlDataAdapter adapter = new SqlDataAdapter(command))
Hello experts. I have been searching for anything about this but found very little. What are the events logged in SQL Server Error Logs aside from Successful/Failed Login, Backup/Restore/Recover database and, start/init sql server? Can we configure this to log other events, like CREATE or DBCC events for example? If so, how? Thanks a lot.
Hi, I have an Access frontend and an SQL Server backend. I use a Query (in Access frontend) to insert in two tables simultaneously. I have a trigger in one of the involved table which update the foreign key in another involved table. I've built an SQL View with exacly!!! the same syntax as my Query in Access. And when I insert a new entry through the SQL View the trigger fires(the foreign key is updated), but when I insert through my Access Query the trigger doesn't fires (the foreign key is not updated). Any idea ?
By Database is heavily used , we use Transaction log backups ever 10 minuts, now someone fired a wrong query , that updated a particular table , the DB is still in use, there are some users working on it , I cant get the DB offline , what can I do to correct the mistake , please advice.
We have an asp web aplication using COM on a SQL Server 2000 database. The application uses COM to perform the database access. On altering data, the code checks the @@rowcount to see if the intented insert or update was succesfull - this is done on changes in various colums in various locations in the code. Now we need to add a trigger to update changed data into other tables. This is because we start migrating to a different data structure - while keeping most of the original code intact.
The problem is now, that the trigger beeing fired erases the @@rowcount. I can imagine others to have experienced the same problem. So, the big question is here:
Is there a solition/workaround to keep the @@rowcount on update/insert/deletes on a table evn if a trigger fires?

I'm trying to cath content of PRINT statements through InfoMessage event. I have subscribed on InfoMessage event through ConnectionEventsVt interface. The problem that event fired only once for statement. For example i have following T-SQL script:
Code Snippet
PRINT 'Message1' PRINT 'Message2' GO
PRINT 'Message3' PRINT 'Message4' GO
When i execute this script InfoMessage event fired twice. First time Error object Description property contains "Message1" text. Second time it contains "Message3" text.
What i'm doing wrong?
Server: MS SQL Sever 2005 OS: Windows XP SP2 IDE: Delphi 7
if service broker is not an option, how can the trigger and sp(s) called by our trigger act asynchronously to the event that fired the trigger in the first place. We are more concerned with the original event being committed than the actions that follow via the trigger.
I would like to AUTOMATICALLY count the event for the month BEFORE today
and
count the events remaining in the month (including those for today).
I can count the events remaining in the month manually with this query (today being March 20):
SELECT Count(EventID) AS [Left for Month], FROM RECalendar WHERE (EventTimeBegin >= DATEADD(DAY, 1, (CONVERT(char(10), GETDATE(), 101))) AND EventTimeBegin < DATEADD(DAY, 12, (CONVERT(char(10), GETDATE(), 101))))
Could anyone provide me with the correct syntax to count the events for the current month before today
and
to count the events remaining in the month, including today.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code. We'reworking on running a SQL trace but if anybody has any input, fireaway.Thanks!create table x(Id int,Account varchar(25),Info int)GOinsert into x values ( 1, 'Smith', 15);insert into x values ( 2, 'SmithX', 25);/* Update trigger tu_x for table x */create trigger tu_xon xfor updateasbegindeclare @TriggerRowCount intset @TriggerRowCount = @@ROWCOUNTif ( @TriggerRowCount = 0 )returnif ( @TriggerRowCount > 1 )beginraiserror( 'tu_x: @@ROWCOUNT[%d] Trigger does not handle @@ROWCOUNT[color=blue]> 1 !', 17, 127, @TriggerRowCount) with seterror, nowait[/color]returnendupdate xsetAccount = left( i.Account, 24) + 'X',Info = i.Infofrom deleted, inserted iwhere x.Account = left( deleted.Account, 24) + 'X'endupdate x set Account = 'Blair', Info = 999 where Account = 'Smith'
What we are trying to do is watch a table in one database for an insert. If something is inserted into a unique ID column, we want to go to another database, on the same server, and look for that same number and place a value in another column for that record. Any ideas?
I'd like to build an application that will react to specific changes todata in a set of tables in a database. The application would replicatethese data changes to another database. The target database won't beSQLServer. Neither is this simple replication, at times the applicationwill need to get extra data from the source database before the targetis updated.In other DBMS systems I am involved with the DBMS has the facilty towrite to an application message queue so that the monitoring applicationonly has to monitor the queue rather than a database. What I'd like todo is something like this:1. Some application changes data in a table.2. A trigger reacts to the change and writes a message to an applicationqueue.3. A windows service/process monitors the queue and picks up themessage. It then carries out whatever replication/DB actions are necessary.This would mean defining a number of new triggers on existing tables anddeveloping the windows service/process. Existing applications and theexisting tables in the database would remain unchanged. I'm not awindows programmer but I have someone in my team who is and who willbuild the windows service/process.The bit I'm unsure about is how a trigger can write to an applicationqueue or communicate with the windows service/process. I may be usingthe wrong terminology as I have more knowledge of Unix than Windows.Could anyone help with how I can do this or suggest any alternativestrategies.Thanks In Advance.Laurence
Just finishing of a large ETL system and have aquestion about the following:-
We have 164 child packages being called from a single parent package which is setup to perform logging to a SQL Server table. Anything that Errors or has Warnings is logged accordingly, however, how do you trap the PackageStart and PackageEnd events? when the child package knows nothing about logging?
My first thought was to have the Parent call the AddEvent SP with the appropriate values, but thought I may check here in case I missed something
I'm trying to catch an error and trigger a control flow to handle it. I introduce a control flow to catch "OnError" event, but , despite muy package has some errors it doesnt work...
Another issue, if i omit an error on a transformation object ( in order let the flow continue executing), can this error be managed by an event or record it in a log?
I would like to know how I can get hold the text for a service and event notifications. What I need is the ability to get hold of a list of the events I'm currently monitoring.
i.e.
Server or database level
I though I would be able to get hold of this in sys.server_event_notifications but it doesn't seem to have any data although my server level event notifcation service is running.
I have the following code and I'm trying to set an event dynamicly in the foreach statement... SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["BvtQueueConnectString2"]); SqlCommand select = new SqlCommand("select top 100 b.jobid as [Job ID], bq.timesubmitted as [Time Submitted], b.timereceived as [Time Received], bq.requestid as [Request ID], bq.timecompleted as [Time Completed], bq.buginfoid as [Bug Info ID], e.eventid as [Event ID], bq.closingeventid as [Closing Event ID], et.eventtype as [Event Type], e.eventtime as [State Start Time], l.twolettercode as [Language], p.projectname as [Project Name], p.packagedesignation as [Package Designation] from bvtjobs b inner join bvtrequestsnew bq on b.jobid = bq.jobid inner join eventlog e on bq.requestid = e.bvtrequestid inner join eventtypes et on e.eventtype = et.eventtypeid inner join languages l on bq.targetlanguage = l.langid inner join projects p on bq.targetplatform = p.projectid order by b.jobid asc", conn); SqlDataAdapter da = new SqlDataAdapter(select); DataSet ds = new DataSet(); conn.Open(); da.Fill(ds); conn.Close(); Table table = new Table();
foreach (DataRow dr in ds.Tables[0].Rows) { TableRow tr = new TableRow(); for (int i = 0; i < dr.ItemArray.Length; i++) { TableCell tc = new TableCell(); tc.Text = dr.ItemArray.GetValue(i).ToString(); tc.BackColor = Color.White; if (dr.ItemArray.GetValue(8).ToString() == "COMPLETE") { tc.BackColor = Color.BlueViolet; } tr.Cells.Add(tc); } table.Rows.Add(tr); } foreach (TableRow tablerow in table.Rows) { TableCell newtc = new TableCell(); Button mybutton = new Button(); newtc.Controls.Add(mybutton); mybutton.Text = "details"; //set the event here tablerow.Cells.Add(newtc); } Panel1.Controls.Add(table); DataBind();
I know how to get the events that start say on May, and I know how to get the events that end on May, however, How would I get the events that start on January and end in July. The month of May should display that event too. so far, as an example, I have: SELECT Events.startDate, Events.endDate
FROM Events WHERE Events.Active = 1 AND startDate BETWEEN convert(smalldatetime, '5/1/2006') AND convert(smalldatetime, '5/31/2006')
I am not sure if I have posted something about this, but I can't believe there is not a single person out there that is using a procedure written in SQL in order to schedule sending of an email, if data hasn't been submitted. I have had some hits and some help from some people but I am pretty much still stuck.
How is everybody else doing these sorts of thing,scheduling an email to be sent to a user if he/she hasn't submitted data,somebody must be doing it? A sample, help ,anything???
I am tracing a SQL Server 2000 production server that gets a queryabout every second. The Event I chose to watch was "Lock:Timeout". Tomy surprise I see many of these come through the trace. Is this normalbehavior? What is "Lock:Timeout" showing me?Thanks,John
Hi,I am trying to debug some queries that are being generated by anexternal program, and I have no way of finding out what the actualsyntax of the query is from within the program itself. This means thatwhen the query fails I am left with only a very unhelpful message.So what I was wondering, was whether there is a way that I can view theactual queries that are sent to SQL server as they happen, or if areal-time solution doesn't exist, then some way I can look back afterthe event and see the syntax of the queries?Ideally, what I would like to do is see the queries in the form theywere sent to the server, ie "SELECT * FROM foo WHERE bar='foobar'", asthis would help me to figure out where the generated queries are goingwrong.Cheers,--Dylan Parryhttp://electricfreedom.org | http://webpageworkshop.co.ukThe opinions stated above are not necessarily representative ofthose of my cats.

Hiwe are considering porting an application from Ingres to SQL Server.Part of the application uses a feature of Ingres called databaseevents. These allow a application to monitor for an event happening inthe database, e.g. a user enters a record meeting certain conditions,the database raises an event including a record ID, and a clientapplication sees the event (without continual explicit polling), readsthe new record and starts processing it.Any idea what the equivalent functionality would be in SQL Server2000, or are applications simply not done that way?TIAChloe CrowderThe British Library
I'm trying to add functionality to a VB 6 application allowingcustomer service to add a customer number to a new customer.Customers are added to the database by sales personnel, and aprospective customer may have multiple rows due to projected ordersfor multiple products. Customer numbers are assigned when a newcustomer makes their first order.I'm using a DataGrid connected to an ADO Data Control. The datacontrol is connected to a view in SQL Server using the 'distinct'directive (I know it's not updatable) to show only one line per newcustomer. What I wish to do is capture the update event (probablythrough the FieldChangeComplete routine of the data control), manuallyassign the newly entered customer number to all appropriate rows inthe database, and cancel the update event with no notifications.I'm having two problems:1. I can't capture the newly entered customer number. The Textproperty of the DataGrid returns the old value of the cell instead ofthe newly entered value. How do I get the edited value?2. Even though I set adStatus = adStatusCancel in theFieldChangeComplete routine, I get a Microsoft DataGrid Control dialogstating 'Operation was Canceled'. How do I avoid this notification?
How is everyone using the logging features of SSIS? What events are relevant to day-to-day operation? Currently we are logging all events except for Diagnostic to a SQL table, and then using event log reporting. What would be the appropriate events used for a production environment?
Need calculating the count of events on each day. I have an event log table as shown below.
DECLARE @EventLog TABLE ( event_id int, status_id varchar(20) , dttm datetime ) INSERT INTO @EventLog SELECT '100','Inplace','01/05/2015 05:00' UNION ALL SELECT '100','Removed','03/05/2015 10:00' UNION ALL SELECT '100','Inplace','05/05/2015 10:41' UNION ALL
[Code] ....
I need an output to look like on each day how many events were in place.
E.g.: for the month on May , Event_id 100 was inplace on 1st and removed on 3rd , so on 1st may 2 event_ids (100, 103) hence 2 .
event_ids - 103 / 104 and inplace the whole month and not removed. so its calculated the count as 2 til towards teh end of the month.
So I need to count of all each event_id in place for each day in may.
Hi, Ive been taking a look at how to consume events from a package when executing programatically.
Ive got some code (copied below) that creates a package programatically, adds a sequence container then within that adds a script task , then executes it using the overloaded method of Package.Execute() that takes an IDtsEvents argument.
My class that implements IDtsEvents simply output a message to the console for each event type.
Weird thing is, when I execute, this is the only output I get:
What I find weird is that I dont get information for loads of other event types. I would at least have expected to see some OnPostExecute events.
Anyone know why i dont see all of the events?
Thanks Jamie
Heres the code:
Code Snippet using System; using System.Collections.Generic; using System.Text; using Microsoft.SqlServer.Dts.Runtime; using Microsoft.SqlServer.Dts.Tasks.ScriptTask; namespace Package_API { class Program { static void Main(string[] args) { Console.WriteLine("Starting..."); Package p = new Package(); p.InteractiveMode = true; p.OfflineMode = true; // Add a Script Task to the package. Sequence s = (Sequence)p.Executables.Add("STOCK:Sequence"); TaskHost taskH = (TaskHost)s.Executables.Add("STOCK:ScriptTask"); // Run the package. DtsEvents events = new DtsEvents(); p.Execute(null,null,events,null,null); //p.Execute(); if (p.ExecutionResult == DTSExecResult.Failure || p.ExecutionStatus == DTSExecStatus.Abend) Console.WriteLine("Package failed or abended"); else Console.WriteLine("Package ran successfully"); Console.ReadLine(); } } }
