I am using the following command to read from the queue. But it returns only one row. I noticed that conversation_handle is unique for all messages. How can I read top 100 or all the rows from the queue in sql server?
RECEIVE *-- #handle=conversation_handle, --#xml=CAST(message_body AS XML) FROM EventData_Destination_Queue
as documentation says:
WHERE
Specifies the conversation or conversation group for the received messages. If omitted, returns messages from the next available
conversation group.
That mean- if next conversation group contains 1 message, it returns just 1 message. So maybe what you want is to group messages in one conversation group at the time of sending them.

Hello guys I want to find a way to identify a query executed for Extended Events in Microsoft SQL Server (to filter the Extended Event with only that executed query)
If i query the system views in SQL Server like this:
SELECT session_id, connection_id
FROM sys.dm_exec_requests
WHERE session_id = ##SPID
I get the connection_id of the current query executing which is unique until SQL Server restarts.
But Extended Events have a different value called 'sqlserver.client_connection_id' which is not the same identifier as 'connection_id' from the table 'sys.dm_exec_requests'.
Do you know where can I find the 'sqlserver.client_connection_id' in system tables? or another solution to unquely identify a executed query?
The client_connection_idin Extended Events (according to SSMS)
Provides the optional identifier provided at connection time by a client
and is the SqlConnection.ClientConnectionId, which is intended to support troubleshooting client connectivity issues.
You can locate the connection ID in the extended events log to see if
the failure was on the server if the extended event for logging
connection ID is enabled. You can also locate the connection ID in the
connection ring buffer (Connectivity troubleshooting in SQL Server
2008 with the Connectivity Ring Buffer) for certain connection errors.
If the connection ID is not in the connection ring buffer, you can
assume a network error.
So this id correlates the client-side and server-side of the connection attempt. For successful connections a row in sys.dm_exec_connections and sys.dm_exec_sessions will be created with different id's.
I'm trying to create an Extended Event with error_reported of all queries. And then filter the results in .xel file using an identifier that tells me that this was from X query.
You can capture the query in the error_reported event, eg:
CREATE EVENT SESSION [errors] ON SERVER
ADD EVENT sqlserver.error_reported(
ACTION
(
sqlserver.client_app_name,
sqlserver.session_id,
sqlserver.sql_text
)
WHERE ([severity]>=(11)))
Extended Evets by default tracks all of the connections and activity on the instance. Your filters in the definition will limit that down.
The sqlserver.client_connection_id includes all of the values from all of the queries - so if you DID know the client connection id then you could identify those results.
I'm not clear what you are trying to filter for with the Extended Event? Are you looking to see where a specific query was executed from or track all the queries on a specific connection?
The other places you can look to get the same connection info are :
SELECT * FROM sys.dm_exec_connections
SELECT * FROM sys.dm_exec_sessions
SELECT * FROM sys.dm_exec_requests
Looking at these might help you link the make the connection.
I have a report which is sent daily which has some no. of rows but I want to send a separate report with a subject which says it is "critical" as it has n no. of rows in it.
How do I schedule this in SSRS?
Thank you!
Create a data driven subscription that only returns results if your table contains n rows.
A Data Driven Subscription would be best if you have the Enterprise version of SQL, but if you don't you'll need to get creative. One method that should work is to create a copy of the existing report (if it's TheNinjaReport call the copy TheNinjaReport_Critical or something), and alter the query so that it throws an error if there aren't the requisite number of rows. When the query throws an error, the subscription will fail and nothing will go to the end user. Something like
IF (SELECT COUNT(*) FROM dbo.ErrorLog) > 100
SELECT *
FROM dbo.ErrorLog
ELSE
RAISERROR('Not a critical number of errors', 16, 1)
This is not ideal because now you have two reports to maintain, but it will get you where you need to be.
I got the following error in Activity Monitor,
The row was not found at the Subscriber when applying the replicated command. (Source: SQL Server, Error number: 20598)
After some research, I found out the error occurs because it's trying to delete records which are not exists in the subscriber(Also are not exists in publisher)
{CALL [dbo].[sp_MSdel_testtable] (241)}
I can manually insert something to the record and the replication will move on. The problem I have right now is I don't how many bad records are there. Is there any fast way to do this? I already spends hours and inserted about 20 records.
Thank you
Re-initialize the subscription via Replication Monitor in SSMS, and generate a new snapshot during re-initialization. This should clear up the missing record issues.
Dude, I [literally] just solved this a few minutes ago. It pushed me about a fifty cent cab ride short of crazy. The replicated database was part of a third party solution to offload their app's reporting. As it turns out, one of their app servers was pointed to our reporting database rather than the live database. Hence, "row not found at subscriber." because they were inserting and deleting records in the subscriber table.
Use distribution.dbo.sp_helpsubscriptionerrors to find the xact_seqno, then you can use distribution.dbo.browsereplcmds and this query
SELECT *
FROM distribution.dbo.MSarticles
WHERE article_id in (
SELECT article_id
FROM MSrepl_commands
WHERE xact_seqno = 0x xact_seqno)
to get more info. Use distribution.dbo.sp_setsubscriptionxactseqno if you want to get that single transaction "un-stuck" or just re-initialize.
I ended up running SQL Profiler on both the publisher and subscriber, then keyed off the tables I found with the queries above. That's when I spotted the DML on the replicated table.
Good luck.
This query will give you all the pending commands for that article, which needs to be sent from distributor to subscriber.
Here you will get multiple records with same xact_seqno_start and xact_seqno_end but with different command ids.
You can check if all are delete commands, you can take primary key column value for all and insert them manually to subscriber server.
EXEC Sp_browsereplcmds
#article_id = 813,
#command_id = 1,
#xact_seqno_start = '0x00099979000038D60001',
#xact_seqno_end = '0x00099979000038D60001',
#publisher_database_id = 1
I have a SQL Server 2008 Service Broker queue that processes messages by calling a CLR stored procedure (which, in turn, transports the messages via HTTP to a third party's REST API). I need to get a handle on "how backed up?" or "how far behind?" this queue is. While I understand that the total number of messages in the queue is a good indicator of progress, what I'm interested in is "how long was the most recently handled message waiting in the queue to be processed?" As best I can tell, selecting from the queue gives you all of the messages in it, but does not give the age of the message. For example:
SELECT TOP 100 *, casted_message_body =
CASE message_type_name WHEN 'X'
THEN CAST(message_body AS NVARCHAR(MAX))
ELSE message_body
END
FROM [SyncReadTargetQueue] WITH(NOLOCK)
But, none of the columns indicate age.
Any ideas?
To get the time when message arrived you could use "security_timestamp" in sys.conversation_endpoints.
How to monitor Service Broker- maybe this helps.
In our project we have requirement that, after receiving sms message from third party
service provider exactly after 3 minutes i need to execute a sql query to update database.
how should i do this , any suggestions are accepted.
** is it possible using stored procedures...
Exactly the scenario is , we are having mediator service application consider it has webservice. from my application when i send a SMS to webservice application via to SMS service provider , this system will push to embedded device , this will make the system to ON. and after 2 min device will send SMS message to pur application thru SMS service provider to say that checking is going on... after receiving this message exactly i need to update database saying that chekcing done succefully. why 3 minutes because exactly after this time device will go Off.
regards,
Mahesh
How exactly are you receiving the SMS Messages. What service is picking them up.
Theres a couple of ways you could do it.
In your Application Code on the SMSReceived Event you could kick off a separate thread to sleep for 180 seconds, and then call your SQL Code.
If you want to do it in the database, you'll need some sort of polling thread.
Record the "TimeReceived" and have a bit flag "PostProcessed"
Then you could just have a job that runs every 60 seconds that goes
SELECT *
FROM ReceivedSMS
WHERE TimeRecieved < dateadd(second, -180, getdatE()) AND
PostProcessed = 0
FOREACH Record - Execute SPROC & Update PostProcessed = 1.
You can use "SQL jobs"

Hope this helps.
Run the stored proc immediately but the first T-SQL line is WAITFOR DELAY '00:03:00' ?
