I used below metioned query to find out if any failover happened in the last 30 minutes
create table #errormsg(duration datetime,errornum int,dbmessage varchar(max))
DECLARE #tags3 VARCHAR(5000)SET #tags3 = (SELECT CAST( t.target_data AS XML ).value('(EventFileTarget/File/#name)[1]', 'VARCHAR(MAX)') FROM sys.dm_xe_sessions s INNER JOIN sys.dm_xe_session_targets t ON s.address = t.event_session_address WHERE t.target_name = 'event_file' and s.name='AlwaysOn_health');
IF #tags3 is Not NULL begin WITH cte_HADR AS (SELECT object_name, CONVERT(XML, event_data) AS data FROM sys.fn_xe_file_target_read_file(#tags3, null, null, null)WHERE object_name = 'error_reported')
insert into #errormsg SELECT data.value('(/event/#timestamp)[1]','datetime')AS [timestamp],data.value('(/event/data[#name=''error_number''])[1]','int') AS [error_number],data.value('(/event/data[#name=''message''])[1]','varchar(max)') AS [message] FROM cte_HADR WHERE data.value('(/event/data[#name=''error_number''])[1]','int') = 1480 select distinct GETDATE() as currenttime, er.duration,dbs.name from #errormsg er inner join sys.databases dbs on er.dbmessage LIKE '%"' +dbs.name+'"%' where er.duration>=(DATEADD(mi,-30,GETDATE()) );
drop table #errormsg;end
else IF OBJECT_ID(N'TempDB.dbo.#errormsg', N'U') IS NOT NULL drop table #errormsg;
But I did not get the result I was expecting because of the "Incorrect Timestamp on Events in Extended Events".
In SSMS -->Management-->Extended Events-->Sessions-->AlwaysOn_health--> click event file.
In that event file,
I checked recently role changed time for 'availablity_replica_state_change'.
In MSSQL log folder--> availablity_replica_state_change time in "AlwaysOn_health" file
timestamp in (1) and (2) needs to be same.
But for me its shows different time. So I didn't get the proper result.
Instead of using extended events, Is there any query to read the MS SQL error logs?
Is there any query to find out if any failover happened in the last 30 minutes?
Please help me to find a solution for this .
I had some help writing this query -- I'm at a bit of a loss because i'm trying to find the the query type or procedure used and i'm not sure what else to add to the query or how to change it.

Based on my comment, give this a try, should get you moving in the right direction on how you can parse the xml and zero in on the specific command.
You might have to update the name spaces in the script below and also add your report name.
But try something like this:
;WITH XMLNAMESPACES (DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition') --You may have to change this based on you SSRS version
SELECT
[Path],
Name,
report_xml.value( '(/Report/DataSources/DataSource/#Name)[1]', 'VARCHAR(50)' ) AS DataSource,
report_xml.value( '(/Report/DataSets/DataSet/Query/CommandText/text())[1]', 'VARCHAR(MAX)' ) AS CommandText,
report_xml.value( '(/Report/DataSets/DataSet/Query/CommandType/text())[1]', 'VARCHAR(100)' ) AS CommandType,
report_xml
FROM
(
SELECT
[Path],
Name,
[Type],
CAST( CAST( content AS VARBINARY(MAX) ) AS XML ) report_xml
FROM dbo.[Catalog]
WHERE Content IS NOT NULL
AND [Type] = 2
) x
WHERE
--use below in where clause if searching for the CommandText. Depending on how the report was developed I would just use the proc name and no brackets or schema.
--Example: if you report was developed as having [dbo].[procName] just use LIKE '%procName%' below. Because other reports could just have dbo.procName.
report_xml.value( '(/Report/DataSets/DataSet/Query/CommandText/text())[1]', 'VARCHAR(MAX)' ) LIKE '%Your Proc Name here%'
--comment out the above and uncomment below if know your report name and want to search for that specific report.
--[x].[Name] = 'The Name Of Your Report'
You're in the right neighborhood... When a report RDL is published its XML is converted into a image data type and stored in dbo.Catalog.Content.
If you convert the image data to VARBINARY(MAX) and then convert to XML, you'll be able to read the XML in plain text.
SELECT TOP (10)
*
FROM
dbo.Catalog c
CROSS APPLY ( VALUES (CONVERT(XML, CONVERT(VARBINARY(MAX), c.Content))) ) cx (content_xml)
WHERE
c.Type = 2;
From there it's just a matter of parsing the XML to dig out what you're looking for. In this case you looking for tags that look like the following...
<DataSet Name="My_stored_proc">
Are you looking for the stored procedure name? If your looking to see where that is at its in the database itself, database > DatabaseName > Programmability > Stored Procedures. If your trying to use the query you built for a report you need to make the stored procedure or change the query type to text and paste it in the box.

Im trying to write a query that will tell me how much time a restore (full or log) has taken on SQL server 2008.
I can run this query to find out how much time the backup took:
select database_name,
[uncompressed_size] = backup_size/1024/1024,
[compressed_size] = compressed_backup_size/1024/1024,
backup_start_date,
backup_finish_date,
datediff(s,backup_start_date,backup_finish_date) as [TimeTaken(s)],
from msdb..backupset b
where type = 'L' -- for log backups
order by b.backup_start_date desc
This query will tell me what is restored but now how much time it took:
select * from msdb..restorehistory
restorehistory has a column backup_set_id which will link to msdb..backupset, but that hold the start and end date for the backup not the restore.
Any idea where to query the start and end time for restores?
To find the RESTORE DATABASE time, I have found that you can use this query:
declare #filepath nvarchar(1000)
SELECT #filepath = cast(value as nvarchar(1000)) FROM [fn_trace_getinfo](NULL)
WHERE [property] = 2 and traceid=1
SELECT *
FROM [fn_trace_gettable](#filepath, DEFAULT)
WHERE TextData LIKE 'RESTORE DATABASE%'
ORDER BY StartTime DESC;
The downside is, you'll notice that, at least on my test server, the EndTime is always NULL.
So, I came up with a second query to try and determine the end time. First of all, I apologize that this is pretty ugly and nested like crazy.
The query below assumes the following:
When a restore is run, for that DatabaseID and ClientProcessID, the next EventSequence contains the TransactionID we need.
I then go and find the max EventSequence for the Transaction
Finally, I select the record that contains RESTORE DATABASE and the maximum transaction associated with that record.
I'm sure someone can probably take what I've done and refine it, but this appears to work on my test environment:
declare #filepath nvarchar(1000)
SELECT #filepath = cast(value as nvarchar(1000)) FROM [fn_trace_getinfo](NULL)
WHERE [property] = 2 and traceid=1
SELECT *
FROM [fn_trace_gettable](#filepath, DEFAULT) F5
INNER JOIN
(
SELECT F4.EventSequence MainSequence,
MAX(F3.EventSequence) MaxEventSequence, F3.TransactionID
FROM [fn_trace_gettable](#filepath, DEFAULT) F3
INNER JOIN
(
SELECT F2.EventSequence, MIN(TransactionID) as TransactionID
FROM [fn_trace_gettable](#filepath, DEFAULT) F1
INNER JOIN
(
SELECT DatabaseID, SPID, StartTime, ClientProcessID, EventSequence
FROM [fn_trace_gettable](#filepath, DEFAULT)
WHERE TextData LIKE 'RESTORE DATABASE%'
) F2 ON F1.DatabaseID = F2.DatabaseID AND F1.SPID = F2.SPID
AND F1.ClientProcessID = F2.ClientProcessID
AND F1.StartTime > F2.StartTime
GROUP BY F2.EventSequence
) F4 ON F3.TransactionID = F4.TransactionID
GROUP BY F3.TransactionID, F4.EventSequence
) F6 ON F5.EventSequence = F6.MainSequence
OR F5.EventSequence = F6.MaxEventSequence
ORDER BY F5.StartTime
EDIT
I made some changes to the query, since one of the test databases I used is case-sensitive and it was losing some records. I also noticed when restoring from disk that the DatabaseID is null, so I'm handling that now as well:
SELECT *
FROM [fn_trace_gettable](#filepath, DEFAULT) F5
INNER JOIN
(
SELECT F4.EventSequence MainSequence,
MAX(F3.EventSequence) MaxEventSequence, F3.TransactionID
FROM [fn_trace_gettable](#filepath, DEFAULT) F3
INNER JOIN
(
SELECT F2.EventSequence, MIN(TransactionID) as TransactionID
FROM [fn_trace_gettable](#filepath, DEFAULT) F1
INNER JOIN
(
SELECT DatabaseID, SPID, StartTime, ClientProcessID, EventSequence
FROM [fn_trace_gettable](#filepath, DEFAULT)
WHERE upper(convert(nvarchar(max), TextData))
LIKE 'RESTORE DATABASE%'
) F2 ON (F1.DatabaseID = F2.DatabaseID OR F2.DatabaseID IS NULL)
AND F1.SPID = F2.SPID
AND F1.ClientProcessID = F2.ClientProcessID
AND F1.StartTime > F2.StartTime
GROUP BY F2.EventSequence
) F4 ON F3.TransactionID = F4.TransactionID
GROUP BY F3.TransactionID, F4.EventSequence
) F6 ON F5.EventSequence = F6.MainSequence
OR F5.EventSequence = F6.MaxEventSequence
ORDER BY F5.StartTime
Make it a Job. Then run it as the Job. Then check the View Job History. Then look at the duration column.
While it is running you can check something like this dmv.
select
d.name
,percent_complete
,dateadd(second,estimated_completion_time/1000, getdate())
, Getdate() as now
,datediff(minute, start_time
, getdate()) as running
, estimated_completion_time/1000/60 as togo
,start_time
, command
from sys.dm_exec_requests req
inner join sys.sysdatabases d on d.dbid = req.database_id
where
req.command LIKE '%RESTORE%'
Or you can use some magic voodoo and interpret the transaction log in the following table function, however the only person I know to understand any info in this log is Paul Randal.
I Know he sometimes checks Server Fault, but don't know if he wonders StackOverflow.
select * from fn_dblog(NULL,NULL)
Hope this helps.
If you manage to use this and find a solution please tell us.
Good Luck!
Is there a way to list the queries that are currently running on MS SQL Server (either through the Enterprise Manager or SQL) and/or who's connected?
I think I've got a very long running query is being execute on one of my database servers and I'd like to track it down and stop it (or the person who keeps starting it).
This will show you the longest running SPIDs on a SQL 2000 or SQL 2005 server:
select
P.spid
, right(convert(varchar,
dateadd(ms, datediff(ms, P.last_batch, getdate()), '1900-01-01'),
121), 12) as 'batch_duration'
, P.program_name
, P.hostname
, P.loginame
from master.dbo.sysprocesses P
where P.spid > 50
and P.status not in ('background', 'sleeping')
and P.cmd not in ('AWAITING COMMAND'
,'MIRROR HANDLER'
,'LAZY WRITER'
,'CHECKPOINT SLEEP'
,'RA MANAGER')
order by batch_duration desc
If you need to see the SQL running for a given spid from the results, use something like this:
declare
#spid int
, #stmt_start int
, #stmt_end int
, #sql_handle binary(20)
set #spid = XXX -- Fill this in
select top 1
#sql_handle = sql_handle
, #stmt_start = case stmt_start when 0 then 0 else stmt_start / 2 end
, #stmt_end = case stmt_end when -1 then -1 else stmt_end / 2 end
from sys.sysprocesses
where spid = #spid
order by ecid
SELECT
SUBSTRING( text,
COALESCE(NULLIF(#stmt_start, 0), 1),
CASE #stmt_end
WHEN -1
THEN DATALENGTH(text)
ELSE
(#stmt_end - #stmt_start)
END
)
FROM ::fn_get_sql(#sql_handle)
If you're running SQL Server 2005 or 2008, you could use the DMV's to find this...
SELECT *
FROM sys.dm_exec_requests
CROSS APPLY sys.dm_exec_sql_text(sql_handle)
More about sys.dm_exec_requests
More about sys.dm_exec_sql_text
You can run the sp_who command to get a list of all the current users, sessions and processes. You can then run the KILL command on any spid that is blocking others.
I would suggest querying the sys views. something similar to
SELECT *
FROM
sys.dm_exec_sessions s
LEFT JOIN sys.dm_exec_connections c
ON s.session_id = c.session_id
LEFT JOIN sys.dm_db_task_space_usage tsu
ON tsu.session_id = s.session_id
LEFT JOIN sys.dm_os_tasks t
ON t.session_id = tsu.session_id
AND t.request_id = tsu.request_id
LEFT JOIN sys.dm_exec_requests r
ON r.session_id = tsu.session_id
AND r.request_id = tsu.request_id
OUTER APPLY sys.dm_exec_sql_text(r.sql_handle) TSQL
This way you can get a TotalPagesAllocated which can help you figure out the spid that is taking all the server resources. There has lots of times when I can't even bring up activity monitor and use these sys views to see what's going on.
I would recommend you reading the following article. I got this reference from here.
As a note, the SQL Server Activity Monitor for SQL Server 2008 can be found by right clicking your current server and going to "Activity Monitor" in the context menu. I found this was easiest way to kill processes if you are using the SQL Server Management Studio.
There are various management views built into the product. On SQL 2000 you'd use sysprocesses. On SQL 2K5 there are more views like sys.dm_exec_connections, sys.dm_exec_sessions and sys.dm_exec_requests.
There are also procedures like sp_who that leverage these views. In 2K5 Management Studio you also get Activity Monitor.
And last but not least there are community contributed scripts like the Who Is Active by Adam Machanic.
SELECT
p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, r.command,
p.program_name, text
FROM
sys.dm_exec_requests AS r,
master.dbo.sysprocesses AS p
CROSS APPLY sys.dm_exec_sql_text(p.sql_handle)
WHERE
p.status NOT IN ('sleeping', 'background')
AND r.session_id = p.spid
Actually, running EXEC sp_who2 in Query Analyzer / Management Studio gives more info than sp_who.
Beyond that you could set up SQL Profiler to watch all of the in and out traffic to the server. Profiler also let you narrow down exactly what you are watching for.
For SQL Server 2008:
START - All Programs - Microsoft SQL Server 2008 - Performance Tools - SQL Server Profiler
Keep in mind that the profiler is truly a logging and watching app. It will continue to log and watch as long as it is running. It could fill up text files or databases or hard drives, so be careful what you have it watch and for how long.
In the Object Explorer, drill-down to: Server -> Management -> Activity Monitor. This will allow you to see all connections on to the current server.
You can use below query to find running last request:
SELECT
der.session_id
,est.TEXT AS QueryText
,der.status
,der.blocking_session_id
,der.cpu_time
,der.total_elapsed_time
FROM sys.dm_exec_requests AS der
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS est
Using below script you can also find number of connection per database:
SELECT
DB_NAME(DBID) AS DataBaseName
,COUNT(DBID) AS NumberOfConnections
,LogiName
FROM sys.sysprocesses
WHERE DBID > 0
GROUP BY DBID, LogiName
For more details please visit:
http://www.dbrnd.com/2015/06/script-to-find-running-process-session-logged-user-in-sql-server/
here is a query that will show any queries that are blocking. I am not entirely sure if it will just show slow queries:
SELECT p.spid
,convert(char(12), d.name) db_name
, program_name
, convert(char(12), l.name) login_name
, convert(char(12), hostname) hostname
, cmd
, p.status
, p.blocked
, login_time
, last_batch
, p.spid
FROM master..sysprocesses p
JOIN master..sysdatabases d ON p.dbid = d.dbid
JOIN master..syslogins l ON p.sid = l.sid
WHERE p.blocked = 0
AND EXISTS ( SELECT 1
FROM master..sysprocesses p2
WHERE p2.blocked = p.spid )
The right script would be like this:
select
p.spid, p.status,p.hostname,p.loginame,p.cpu,r.start_time, t.text
from sys.dm_exec_requests as r, sys.sysprocesses p
cross apply sys.dm_exec_sql_text(p.sql_handle) t
where p.status not in ('sleeping', 'background')
and r.session_id=p.spid
SELECT
p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, t.text
FROM
sys.dm_exec_requests as r,
master.dbo.sysprocesses as p
CROSS APPLY sys.dm_exec_sql_text(p.sql_handle) t
WHERE
p.status NOT IN ('sleeping', 'background')
AND r.session_id = p.spid
And
KILL #spid
in 2005 you can right click on a database, go to reports and there's a whole list of reports on transitions and locks etc...
Trying to put things together (hope to be helpful):
SELECT
p.spid,
RIGHT(CONVERT(varchar, DATEADD(ms, DATEDIFF(ms, p.last_batch, GETDATE()), '1900-01-01'), 121), 12) AS [batch_duration],
p.[program_name],
p.hostname,
MAX(p.loginame) AS loginame,
(SELECT SUBSTRING(text, COALESCE(NULLIF(spid.stmt_start, 0), 1) + 1, CASE spid.stmt_end WHEN -1 THEN DATALENGTH(text) ELSE (spid.stmt_end - spid.stmt_start) END) FROM ::fn_get_sql(spid.[sql_handle])) AS [sql]
FROM
master.dbo.sysprocesses p
LEFT JOIN (
SELECT
ROW_NUMBER() OVER(PARTITION BY spid ORDER BY ecid) AS i,
spid,
[sql_handle],
CASE stmt_start WHEN 0 THEN 0 ELSE stmt_start / 2 END AS stmt_start,
CASE stmt_end WHEN -1 THEN -1 ELSE stmt_end / 2 END AS stmt_end
FROM sys.sysprocesses
) spid ON p.spid = spid.spid AND spid.i = 1
WHERE
p.spid > 50
AND p.status NOT IN ('background', 'sleeping')
AND p.cmd NOT IN ('AWAITING COMMAND', 'MIRROR HANDLER', 'LAZY WRITER', 'CHECKPOINT SLEEP', 'RA MANAGER')
GROUP BY
p.spid,
p.last_batch,
p.[program_name],
p.hostname,
spid.stmt_start,
spid.stmt_end,
spid.[sql_handle]
ORDER BY
batch_duration DESC,
p.spid
;
Use Sql Server Profiler (tools menu) to monitor executing queries and use activity monitor in Management studio to see how is connected and if their connection is blocking other connections.
You should try very usefull procedure sp_whoIsActive which can be found here: http://whoisactive.com and it is free.
