I have noticed something strange on the select statement that you can use on query notification.
I have a table that contains a compute column let's call it "Calculate".
If I subscribe to query notification:
Select ID from table
the subscription fails.
The column Calculate doesn't use the column ID.
Why??
for me it shouldn't be the case
Thankx

WHERE location_id IN (SELECT location_id from location_table WHERE account_id = 998)
it produces my desired data but it takes 3 minutes to run the query... is there any way to make this faster?... thank you so much...
Hi,
I have a table called notes, with thousands of rows of "notes" entered by customer services agents. Each row has an account number, date and username columns.
An account can have many notes on thetable.
How can I select the last two notes on the table left for each account? Trying to use select top 2, but of course it's only giving me the top 2 notes for ALL accounts.
Please help.
Thanks very much.
In my select statement, I return a column for 'datediff' using a CASEquery. I call this column 'Elapsed_days'is there anyway I can use this result later on in the same select? IEI want to refer to 'elasped days' in another CASE query rather thanhave to re-write something which incorporates the original one.Simpler the better - I'm new!Make any sense?Hope so

Hi folks,
Hope you are all well.
I am using a CASE statement within a SELECT query to sum up values for different customers.
SELECT CR_CUST.Customer_Code,
'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END
FROM CR_CUST
INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code
INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code
WHERE (CR_PROD.Part_Class_Code = 1 OR
CR_PROD.Part_Class_Code = 7 OR
CR_PROD.Part_Class_Code = 8)
GROUP BY CR_CUST.Customer_Code,
CR_PROD.Part_Class_Code
The above query produces the following results...
Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 .00 .00
02347 7606.49 .00 .00
02210 .00 12618.42 .00
02347 .00 13131.63 .00
02210 .00 .00 4505.44
02347 .00 .00 5018.03
My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so...
Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 12618.42 4505.44
02347 7606.49 13131.63 5018.03
I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table.
SELECT Customer_Code,
SUM(General_01),
SUM(General_07),
SUM(General_08)
FROM #MyTempTable
GROUP BY Customer_Code
Thanks in advance,

I am trying to apply the logic from the following resource: URL....but cannot get it to work with my logic for some reason.For example, the following query:
;WITH CTE1 AS (SELECT CONVERT(VARCHAR, GETDATE(), 120) AS Col1),
CTE2 AS (SELECT CONVERT(VARCHAR, GETDATE(), 111) AS Col2)
SELECT CTE1.Col1,CTE2.Col2
FROM CTE1
CROSS JOIN CTE2
GO
Produces the following output:
Col1 | Col2
2014-05-08 10:55:54 | 2014/05/08
But, as soon as I try to do something else like:
;WITH CTE1 AS (SELECT COUNT(login) FROM userinfo AS Col1),
CTE2 AS (SELECT COUNT(login) FROM userinfo AS Col2)
SELECT CTE1.Col1,CTE2.Col2
FROM CTE1
CROSS JOIN CTE2
GO
I receive the following errors:
Msg 8155, Level 16, State 2, Line 1
No column name was specified for column 1 of 'CTE1'.
Msg 8155, Level 16, State 2, Line 2

Are there limitations when trying to use multiple CTE in a single query?

I need to insert data into a table based on the results returned by a select statement. Basically, the select statement below gives me a list of all the work orders created in the last hour.
select worknumber from worksorderhdr where date_created > DATEADD(HOUR, -1, GETDATE())
This might return anywhere between 5 and 50 records each time. What I then need to do is use each of the work numbers returned to create a record in the spec_checklist_remind table. The other details in the insert statement will be the same for each insert, it's just the worknumber from the select statement that needs to be added to the insert where the ?? are below:
INSERT INTO spec_checklist_remind (form, record_type, linked_to_worknumber, spec_checklist_id) values (5, 0, '??',52)"
I am wondering if there is a direct query in this case:
I am developing a program to a company which simply sells services
One service may have different prices for different types of clients
The price of any service for any client can change at any time, and I should be able to trace these changes at any time
I made the following tables (simplified): (asterisk for primary key)
(Table) (Fields)
CLIENT_TYPES : ID*, ClientTypeName
SERVICES : ID*, ServiceName
PRICES : ServiceID*, ClientTypeID*, Price, Date*
ORDERS : ID*, Date, ClientTypeID
ORDER_SERVICES : OrderID*, ServiceID*
The field in bold is the area of the question
This is a sample data in the PRICES table:
ServiceID ClientTypeID Price Date1 1 100 1/1/20072 1 150 1/1/20071 2 90 1/1/20072 2 135 1/1/2007
Now if I want to update a price of service 1 for clienttype 1, I add the following row:
1 1 100 1/1/2008
So one product for one client can have any number of prices with different dates
The following query:
SELECT * FROM PRICES WHERE ClientTypeID = 1
will retrieve all prices with repeats for a specific client (#1 here)
What I want is a query to retrieve the most recent prices for specific client for all products, even if a query on query
If there is commemts on table design please tell me
thanks for any one who provides help

hi,
When SQL server notifies the application that the records in a table has changed, is there a way to know which record has changed from the application?
Let me give an eg.
Consider that we have a table customer. We have registered for a notfication for 2 customers, say Cust id 1 and Cust id 2. Now , when records for these two customers changes we get a notification. Is there a way in .Net by whihc we can get whihc customer has been modified?
Thanks
Man.
I've got an application that's using query notifications with a two-user setup (a user that starts the dependency running, and an application user that subscribes to it). I'm having problems getting the query notifications to go through however... according to the Profiler, when the application user does something that triggers a query notification, it causes this error:
This message could not be delivered because the user with ID [application user] in database ID [database] does not have permission to send to the service. Service name: SqlQueryNotificationService-[guid].
The problem is that [guid] is different each time, and there doesn't seem to be a generic "grant send on all services" statement, so I can't grant send on the particular service in question to the application user to get rid of the error. (If I grant db_owner to the application user, the problem goes away and everything works, but I'd rather not do that. The application user already has subscribe query notifications, receive on QueryNotificationErrorsQueue, and references on contract::...PostQueryNotification.)
Obviously I'm doing something wrong, but I am completely out of ideas and can't seem to find anything new to try. Any ideas? Thanks.
After having problems with SqlDependency logging an infinite number of errors I've rewritten my code to use SqlNotificationRequest instead. Now I have a different kind of cleanup problem and am looking for help.
My code registers to be notified when table data is changed. When the event triggers, it re-registers. It works fine. The problem comes when my subscribing program ends: it orphans the last subscription. When the program re-starts it subscribes as before, but now there are now two subscriptions (or three, or however many times my program is shut down). As an Admin I can run KILL QUERY NOTIFICATION SUBSCRIPTION ALL; I can even hard code this into my app as it is the only one (for now) using this instance of SS. But there must be a better way.
When I subscribe (.NET) how do I get the subscription id? Then I could just KILL that single id when my code shuts down. Specifically what code should I include in StopListener()? Thank you.
public void StartListener()
{
// starts a new thread whose sole purpose is to sleep until waked
Debug.WriteLine( "RequestNotification: StartListener" );
if( null == _listener )
{
_listener = new Thread( Listen );
_listener.Name = _threadName;
_listener.IsBackground = true; // essential!
_listener.Start();
}
}
public void StopListener()
{
Debug.WriteLine( "RequestNotification: StopListener" );
// not necessary, but good practice
_listener.Abort();
_listener = null;
Debug.WriteLine( "RequestNotification: Listener aborted..." );
}
private void Listen()
{
// infinite loop on this thread: keep listening even after
// receiving notification
while( true )
{
// connects to SqlServer queue and sleeps until a notification msg arrives
using( SqlConnection conn = new SqlConnection( _connect ) )
{
conn.Open();
Debug.WriteLine( "RequestNotification: Listen connection opened..." );
using( SqlCommand cmd = conn.CreateCommand() )
{
cmd.CommandText = "WAITFOR ( RECEIVE * FROM " + _queue + ");";
cmd.CommandTimeout = 0; // _notificationTimeout + 100;
try
{
// the thread is blocked until the waitfor event occurs.
SqlDataReader reader = cmd.ExecuteReader();
// the waitfor has triggered
while( reader.Read() )
{
// messageText = System.Text.ASCIIEncoding.ASCII.GetString( (byte[]) reader.GetValue( 13 ) ).ToString();
}
// and now we need to hand things back to the user's passed
// delegate, ensure we're back on the UI thread as well
//object[] args = { this, EventArgs.Empty };
Debug.WriteLine( "RequestNotification: Notification received." );
SqlNotificationEventArgs e = new SqlNotificationEventArgs( SqlNotificationType.Change, SqlNotificationInfo.AlreadyChanged, SqlNotificationSource.Database );
_delegate( this, e );

Hi All
In Work , we created a Cache component that serves a large business application, we are subscribing to almost 200 queries , the component worked quite well in the first few months of the development, but lately i am getting notification events that contain "Error" in the SqlNotificationEventArgs of the event , the "Source" value is "Client".
I have no idea what might cause this error event , we are close to "go live" with our product and we cannot depend on the Query Notification mechanism until this problem is solved.
Can it be a DataBase problem? Application Problem?
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
Hi all,
I am looking at replacing a polled system with Query Notification. However when I create the SqlDependency I need to be sure I have the correct permissions. I check the SqlClientPermissions via the Demand() method, but also want to ensure I have the correct DB permission given my current connection string. As I understand it I need to have the following permissions:
CREATE PROCEDURE, QUEUE, and SERVICE permissions
SUBSCRIBE QUERY NOTIFICATIONS
SELECT on underlying tables
RECEIVE on QueryNotificationErrorsQueue
I check most of these via the 'has_perms_by_name' function, but cannot find the correct syntax to check for RECEIVE on QueryNotificationErrorsQueue. I would also love to find a way to do this via SMO instead of issuing SQl commands. Also am I missing any checks ....
Finally, I have also run into the problem whereby SQL issues the following error:
The activated proc [dbo].[SqlQueryNotificationStoredProcedure-1fd90369-7781-4bad-a1b7-e1b56e328374] running on queue ImlHostDB.dbo.SqlQueryNotificationService-1fd90369-7781-4bad-a1b7-e1b56e328374 output the following: 'Could not obtain information about Windows NT group/user 'EMEADyerN', error code 0x54b.'
I ran into this issue when I bought my machine out of sleep mode with it no longer connected to the network. Is their no way to get a error notification. In this situation I will just stop seeing notification and without looing at the ErrorLog believe their is nothing wrong.
Many Thanks, Nick
Hi Guys,
I'm having some problems setting up a SQL Server 2005 Query Notification application. I've only recently moved from SQL Server 2000 so 2005 is still a little alien to me!
I've followed example found on the internet in the following steps:
1.
ALTER DATABASE <dbname> SET ENABLE_BROKER
2.
GRANT CREATE PROCEDURE TO <user>
GRANT CREATE QUEUE TO <user>
GRANT CREATE SERVICE TO <user>
GRANT SUBSCRIBE QUERY NOTIFICATIONS TO <user>
GRANT RECEIVE ON QueryNotificationErrorsQueue TO <user>
3.
ALTER DATABASE <dbname> SET TRUSTWORTHY ON
The application developers have also followed the same example setting up SQL cache and the connection code. When they start the application I can see the connection in the activity monitor but it has a status of SUSPENDED. I've also checked the view:
SELECT * FROM sys.dm_qn_subscriptions
There are no subscriptions setup I can however see that there is a new SP created. I tried to creating master keys as well but I'm not sure what the reasoning behind this is.
Is there anything else I need to take into consideration or check? When I change the data which they use for their select statement SQL profiler doesn't register anything (except the update). I have however seen this:
exec sp_executesql N'END CONVERSATION @p1; BEGIN CONVERSATION TIMER (''69e2c786-9d33-dc11-a751-0050568146e8'') TIMEOUT = 120; WAITFOR(RECEIVE TOP (1) message_type_name,
conversation_handle, cast(message_body AS XML) as message_body from [SqlQueryNotificationService-5fb25d04-6ef6-47e6-9406-854f15e16eb7]), TIMEOUT @p2;',N'@p2 int,@p1
uniqueidentifier',@p2=60000,@p1='BD98F6B4-A133-DC11-A751-0050568146E8'
This occurs when they refresh the page.
Any ideas?
Cheers!

I have been testing SQLDependency and I have a two questions;
1) When using a stored procedure to run the dependency query, using a "clean" procedure (containing nothing but a select statement), works fine. Adding try..catch (which is a part of our coding standards), results in the subscription firing immediately because of an invalid query. Is this by design? If so, how can I implement error handling.
2) How does SQLDependency handle SQL Server restarts?
I see two options:
a) The subscription is fired listing a server restart message in the related service broker queue, but as far as I can tell, SQLDependency has no way of handling these messages given the connection has been broken. (Establishing a new connection and dependency won€™t read the said messages).
b) The SQLDependency listener on the client raises an error for the connection being terminated. Can I relay on this event to recreate a connection and dependency?
Help will be appriciated

Dear,
I have designed a SiteMap provider for SQL Server. But I am worried about the notification service of SQL Server. My SiteMap requires service broker enabled in SQL Server. When I have web farm (multiple clustered server) does the Sql Server service broker notify all the web servers? Or, it notifies only the server request?
Have anubody implement such scenario? Looking forward for your reply.
Sincere Regards,Sultan
Two days ago I discovered that the drive on our test SqlServer2005 was full. The current Error_log had 54+ Gb (yes Gb) of records. Not only did I delete the file I restarted SS and the server.
That afternoon, I discovered that the current log had 33,678 records! I believe 33,616 of the records came from a single run of my app and set of program events. Obviously I'm doing something wrong in my Query Notification implementation and testing. And yet, when I try to to deliberately trigger the phenomenon, I can not.
Here is the head of the exported log file; the two msgs (query dialog closed and cannot drop queue) alternate thousands and thousands of times form a single test run. What is going on?! Pls help!

Hi All
We built a Cache component that take advantage of the SQL Server 2005 query notification mechanism, all went well , we tested the component in a console application , and notifications kept coming for as long time as the console application ran.
When we initiate our Cache Component in our web service global.asx application start event , the query notification works for a few minutes , but if we came after 10 minutes or so , we stoped getting notifications from sql, the SQL Server queue is empty , and all is showing that there is nothing wrong on the DB side...
Our Cache component is a Singleton class , that perform all registrations ,catch the notification events and resubscribe for notifications.
What can be the problem? is our Cache component object are being collected by GC?
Does IIS disposes the SQL Connection that the Query notification uses?
We are on a crisis...
Thanks in advance.
We are in development stage of an application which uses Query Notification feature of SQL Server 2005. When the development started what the development team did was, they just Enabled broker on the database by SET ENABLE_Broker statement and they started using Query Notification. Now the application is in testing phase and when we test with many user, the performance is really slow. What i want to know is , when we use Query Notification what all are the setting to be done at the database level. Is this setting enough. And also how can i tune this system. any useful link is appreciated.
thanks in advance

I'm using query notifications and it worked fine as long as I just edited the data that the "query points to" (one table). That is, my graphical represenation of the data (in a gridview) was updated correctly with the new data 1ms after I changed it, just like it should.
When I inserted a new row to the table the query notification stopped working, meaning my gridview wasn't updated. Any idea of why? Also, after this, not even editing of the data made the query notification trigger so it must have totally stopped.
Thanks in advance

The title says it all. You can do it from a ADO.Net client so why not from TSQL.
It all uses the service broker stuff so why not?
