How to check when autogrowth is done last? - sql

In sql server 2005, the autogrowth is enabled by size.
Is there any way to check when autogrowth on data and log file happened last?

SSMS, right click your db, go to reports->standard reports->disk usage and look for Autogrow/Autoshrink events .
Hopefully you have the correct trace levels set up, if not you might have some issues finding out history.

Here's how to do it without using the sql reports(link, followed by relevant TSQL):
https://sqlblog.org/2007/01/11/reviewing-autogrow-events-from-the-default-trace
DECLARE #path NVARCHAR(260);
SELECT
#path = REVERSE(SUBSTRING(REVERSE([path]),
CHARINDEX('\', REVERSE([path])), 260)) + N'log.trc'
FROM sys.traces
WHERE is_default = 1;
SELECT
DatabaseName,
[FileName],
SPID,
Duration,
StartTime,
EndTime,
FileType = CASE EventClass
WHEN 92 THEN 'Data'
WHEN 93 THEN 'Log'
END
FROM sys.fn_trace_gettable(#path, DEFAULT)
WHERE
EventClass IN (92,93)
ORDER BY
StartTime DESC;

SQL to get whole words till end from the keyword

Consider I have text from the field (notes) as below:
Please check http://example.com
I want a SQL query which fetches the link part only. That is to find keyword http and print till the last.
Output:
http://example.com
Also if the text field doesnt have any link, can we print NA?
CASE WHEN sys like '%Clo%'
THEN RIGHT( i.notes,LEN(i.notes) - CHARINDEX('http',i.notes,1)+1)
ELSE "No Link Available" END AS Cl_Link
For SQL Server you can consider this below logic-
DECLARE #T VARCHAR(MAX) = 'Please check http://example.com'
SELECT RIGHT(#T,LEN(#T) - CHARINDEX('http:',#T,1)+1)
For MySQL-
SET #T = 'Please check http://example.com';
SELECT RIGHT(#T,LENGTH(#T) - POSITION("http:" IN #T)+1)
In case of select query using table, queries will be-
-- SQL Server
SELECT RIGHT(column_name,LEN(column_name) - CHARINDEX('http:',column_name,1)+1) FROM your_table_name
-- MySQL
SELECT RIGHT(column_name,LENGTH(column_name) - POSITION("http:" IN column_name)+1) FROM your_table_name
To apply 'NA' when no link available, please use the below logic-
DECLARE #T VARCHAR(MAX) = 'Please check http://example.com'
SELECT
CASE
WHEN CHARINDEX('http:',#T,1) >= 1 THEN RIGHT(#T,LEN(#T) - CHARINDEX('http:',#T,1)+1)
ELSE 'NA'
END
Below is the query for your reference, executed on mysql:
SELECT substr(columnname,locate('http',columnname)) as link
FROM `tablename` where column=value
For MySQL try this:
select REGEXP_SUBSTR(text_column, 'http\:\/\/([\\w\\.\\S]+)') from mytest

Last modification Date file system by creating a script

I need to create an script or query to give me the last modification date of a file system. I have the below query and it works perfectly for an overwitted backup file. but I need to run it for *.bak that shows me the latest backup file modification date during many backup files:
--
if exists(select 1 from tempdb..sysobjects where name='##tmp')
drop table ##tmp
create table ##tmp(mdate varchar(8000))
insert ##tmp
exec master.dbo.xp_cmdshell 'dir g:\SQL_Backup\filename.bak' -- (I need the --last backup file name which the name keep changing every week)
set rowcount 5
delete from ##tmp
set rowcount 0
select top(1) substring(mdate,1,20) as 'Last modified date' from ##tmp
I've never worked with these views, so this really need a reality check before you really integrate it, but this may help:
select
top 1 backupSetName = bs.name,
backupFilePath = bf.physical_name,
backupFileLogicalName = bf.logical_name,
bs.backup_start_date,
bs.backup_finish_date
from msdb.dbo.backupfile bf
join msdb.dbo.backupSet bs on bf.backup_set_id = bs.backup_set_id
where right(bf.physical_name,4) = '.mdf'
order by backup_finish_date desc;
"Backup Set" records the actual dates. Since it is one-to-many with "Backup Files", it means that the '.mdf' and '.ldf' file dates are recorded together. I just excluded the latter in the above output.
I can run the PowerShell script and store in in sql server job. It ran successfully.
$source = "\00.0.00.00\your file location"
$filetype = "dif" (or "bak")
Get-ChildItem "$source*" -Include "*.$filetype" | sort LastWriteTime | select -last 1
$datetime=[datetime]::Today
if($datetime.DayOfWeek -match 'Monday'){
Write-Host "YES"
}elseif($datetime.DayOfWeek -match 'Tuesday|Thursday|Saturday'){
Write-Host "NO"
}else{
Write-Host "YES"
}

Checking for unused space in SQL Server database file

I am trying to determine how much space is available in a SQL Server database file using this slightly modified version of query I found somewhere on SO.
SELECT
GETDATE() AS [Timestamp],
[TYPE] = A.TYPE_DESC,
[FILE_Name] = A.name,
[FILESIZE_MB] = CONVERT(DECIMAL(10, 2), A.SIZE / 128.0),
[USEDSPACE_MB] = CONVERT(DECIMAL(10, 2), A.SIZE / 128.0 - ((SIZE / 128.0) - CAST(FILEPROPERTY(A.NAME, 'SPACEUSED') AS INT) / 128.0)),
[FREESPACE_MB] = CONVERT(DECIMAL(10, 2), A.SIZE / 128.0 - CAST(FILEPROPERTY(A.NAME, 'SPACEUSED') AS INT) / 128.0),
[FREESPACE_%] = CONVERT(DECIMAL(10, 2), ((A.SIZE / 128.0 - CAST(FILEPROPERTY(A.NAME, 'SPACEUSED') AS INT) / 128.0) / (A.SIZE / 128.0)) * 100),
[FILEGROUP_NAME] = fg.name,
[File_Location] = A.PHYSICAL_NAME
FROM
sys.database_files A
LEFT JOIN
sys.filegroups fg ON A.data_space_id = fg.data_space_id
WHERE
A.TYPE_DESC NOT LIKE 'LOG'
ORDER BY
A.TYPE desc, A.NAME;
Since the database file does not shrink when data is deleted from the database, the query does not quite provide all the information I am looking for.
Is there any way to tell how much actual data is contained within the SpaceUsed file property (vs. available space due to deleted records, etc.)? Or is the only option to do something like DBCC SHRINKDATABASE and change the physical size of the file?
I have looked at sp_spaceused, sys.dm_db_index_physical_stats, and quite a few other things but so far have not come up with a solution.
Update: I've found something that I think is a bit closer to what I need, although I'm not sure it is quite right. Calculating the space used from the page count / average page space used looks like a value closer to what I'm expecting.
SELECT
page_count,
avg_page_space_used_in_percent
FROM
sys.dm_db_index_physical_stats(db_id('TestDB'), NULL, NULL, NULL, 'Detailed')
In SSMS, try right clicking on the database, go to reports, then standard reports, and then select disk usage. If that doesn't work for you, maybe one of the other standard reports will.
Below the pie charts on the standard disc usage report, you can see the disc space used by data files
There are a few ways to do this, my personal favorite is the undocumented DBCC command ShowFileStats. It outputs a list of data files for a database, the total number of extents on disk, and the actual number of extents being used.
For those that do not remember, an extent is 8 pages, and a page is 8 kilobytes in size. So a little math on these two outputs should give you the information you are looking for. Here is a quick sample script.
Note that the DBCC command runs in context of the current database. You could modify this and turn it into a little loop.
IF OBJECT_ID('tempdb..#tempDataUsage') IS NOT NULL DROP TABLE #tempDataUsage
CREATE TABLE #tempDataUsage
(
[Fileid] INT,
[FileGroup] INT,
[TotalExtents] BIGINT,
[UsedExtents] BIGINT,
[Name] sysname,
[FileName] varchar(256)
)
DECLARE #SQLStatement NVARCHAR(400) = 'USE msdb
DBCC ShowFileStats'
INSERT INTO #tempDataUsage
EXEC (#SQLStatement)
SELECT
(TotalExtents * 8 * 8) AS totalSpaceOndiskKB,
(UsedExtents * 8 * 8) AS SpaceActuallyUsedKB,
Name AS DbName,
FileName
FROM
#tempDataUsage

T-SQL: Stop query after certain time

I am looking to run a query in t-SQL (MS SQL SMS) that will stop after X number of seconds. Say 30 seconds. My goal is to stop a query after 6 minutes. I know the query is not correct, but wanted to give you an idea.
Select * from DB_Table
where (gatedate()+datepart(seconds,'00:00:30')) < getdate()
In SQL Server Management Studio, bring up the options dialog (Tools..Options). Drill down to "Query Execution/SQL Server/General". You should see something like this:
The Execution time-out setting is what you want. A value of 0 specifies an infinite time-out. A positive value the time-out limit in seconds.
NOTE: this value "is the cumulative time-out for all network reads during command execution or processing of the results. A time-out can still occur after the first row is returned, and does not include user processing time, only network read time." (per MSDN).
If you are using ADO.Net (System.Data.SqlClient), the SqlCommand object's CommandTimeout property is what you want. The connect string timeout verb: Connect Timeout, Connection Timeout or Timeout specifies how long to wait whilst establishing a connection with SQL Server. It's got nothing to do with query execution.
Yes, let's try it out.
This is a query that will run for 6 minutes:
DECLARE #i INT = 1;
WHILE (#i <= 360)
BEGIN
WAITFOR DELAY '00:00:01'
print FORMAT(GETDATE(),'hh:mm:ss')
SET #i = #i + 1;
END
Now create an Agent Job that will run every 10 seconds with this step:
-- Put here a part of the code you are targeting or even the whole query
DECLARE #Search_for_query NVARCHAR(300) SET #Search_for_query = '%FORMAT(GETDATE(),''hh:mm:ss'')%'
-- Define the maximum time you want the query to run
DECLARE #Time_to_run_in_minutes INT SET #Time_to_run_in_minutes = 1
DECLARE #SPID_older_than smallint
SET #SPID_older_than = (
SELECT
--text,
session_id
--,start_time
FROM sys.dm_exec_requests
CROSS APPLY sys.dm_exec_sql_text(sql_handle)
WHERE text LIKE #Search_for_query
AND text NOT LIKE '%sys.dm_exec_sql_text(sql_handle)%' -- This will avoid the killing job to kill itself
AND start_time < DATEADD(MINUTE, -#Time_to_run_in_minutes, GETDATE())
)
-- SELECT #SPID_older_than -- Use this for testing
DECLARE #SQL nvarchar(1000)
SET #SQL = 'KILL ' + CAST(#SPID_older_than as varchar(20))
EXEC (#SQL)
Make sure the job is run by sa or some valid alternative.
Now you can adapt it to your code by changing:
#Search_for_query = put here a part of the query you are looking for
#Time_to_run_in_minutes = the max number of minutes you want the job to run
What will you be using to execute this query? If you create a .NET application, the timeout for stored procedures by default is 30 seconds. You can change the timeout to be 6 minutes if you wish by changing SqlCommand.CommandTimeout
In SQL Server, I just right click on the connection in the left Object Explorer pane, choose Activity Monitor, then Processes, right click the query that's running, and choose Kill Process.

How to see query history in SQL Server Management Studio

Is the query history stored in some log files? If yes, can you tell me how to find their location? If not, can you give me any advice on how to see it?
[Since this question will likely be closed as a duplicate.]
If SQL Server hasn't been restarted (and the plan hasn't been evicted, etc.), you may be able to find the query in the plan cache.
SELECT t.[text]
FROM sys.dm_exec_cached_plans AS p
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%';
If you lost the file because Management Studio crashed, you might be able to find recovery files here:
C:\Users\<you>\Documents\SQL Server Management Studio\Backup Files\
Otherwise you'll need to use something else going forward to help you save your query history, like SSMS Tools Pack as mentioned in Ed Harper's answer - though it isn't free in SQL Server 2012+. Or you can set up some lightweight tracing filtered on your login or host name (but please use a server-side trace, not Profiler, for this).
As #Nenad-Zivkovic commented, it might be helpful to join on sys.dm_exec_query_stats and order by last_execution_time:
SELECT t.[text], s.last_execution_time
FROM sys.dm_exec_cached_plans AS p
INNER JOIN sys.dm_exec_query_stats AS s
ON p.plan_handle = s.plan_handle
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%'
ORDER BY s.last_execution_time DESC;
Late one but hopefully useful since it adds more details…
There is no way to see queries executed in SSMS by default. There are several options though.
Reading transaction log – this is not an easy thing to do because its in proprietary format. However if you need to see queries that were executed historically (except SELECT) this is the only way.
You can use third party tools for this such as ApexSQL Log and SQL Log Rescue (free but SQL 2000 only). Check out this thread for more details here SQL Server Transaction Log Explorer/Analyzer
SQL Server profiler – best suited if you just want to start auditing and you are not interested in what happened earlier. Make sure you use filters to select only transactions you need. Otherwise you’ll end up with ton of data very quickly.
SQL Server trace - best suited if you want to capture all or most commands and keep them in trace file that can be parsed later.
Triggers – best suited if you want to capture DML (except select) and store these somewhere in the database
Query history can be viewed using the system views:
sys.dm_exec_query_stats
sys.dm_exec_sql_text
sys.dm_exec_query_plan
For example, using the following query:
select top(100)
creation_time,
last_execution_time,
execution_count,
total_worker_time/1000 as CPU,
convert(money, (total_worker_time))/(execution_count*1000)as [AvgCPUTime],

convert(money, (total_logical_reads+total_logical_writes)/(execution_count + 0.0)) as [AvgIO],
[sql_handle],

convert(money, total_grant_kb/(execution_count + 0.0)) as [AvgGrantKb],
total_used_grant_kb,
convert(money, total_used_grant_kb/(execution_count + 0.0)) as [AvgUsedGrantKb],
total_ideal_grant_kb,
convert(money, total_ideal_grant_kb/(execution_count + 0.0)) as [AvgIdealGrantKb],
total_reserved_threads,
convert(money, total_reserved_threads/(execution_count + 0.0)) as [AvgReservedThreads],

This request displays all active requests and all those requests that explicitly block active requests.
All these and other useful scripts are implemented as representations in the SRV database, which is distributed freely.
For example, the first script came from the view [inf].[vBigQuery], and the second came from view [inf].[vRequests].
There are also various third-party solutions for query history.
I use Query Manager from Dbeaver:
and Query Execution History from SQL Tools, which is embedded in SSMS:
You can Monitor SQL queries by SQL Profiler if you need it
The system doesn't record queries in that way. If you know you want to do that ahead of time though, you can use SQL Profiler to record what is coming in and track queries during the time Profiler is running.
As others have noted, you can use SQL Profiler, but you can also leverage it's functionality through sp_trace_* system stored procedures. For example, this SQL snippet will (on 2000 at least; I think it's the same for SQL 2008 but you'll have to double-check) catch RPC:Completed and SQL:BatchCompleted events for all queries that take over 10 seconds to run, and save the output to a tracefile that you can open up in SQL profiler at a later date:
DECLARE #TraceID INT
DECLARE #ON BIT
DECLARE #RetVal INT
SET #ON = 1
exec #RetVal = sp_trace_create #TraceID OUTPUT, 2, N'Y:\TraceFile.trc'
print 'This trace is Trace ID = ' + CAST(#TraceID AS NVARCHAR)
print 'Return value = ' + CAST(#RetVal AS NVARCHAR)
-- 10 = RPC:Completed
exec sp_trace_setevent #TraceID, 10, 1, #ON -- Textdata
exec sp_trace_setevent #TraceID, 10, 3, #ON -- DatabaseID
exec sp_trace_setevent #TraceID, 10, 12, #ON -- SPID
exec sp_trace_setevent #TraceID, 10, 13, #ON -- Duration
exec sp_trace_setevent #TraceID, 10, 14, #ON -- StartTime
exec sp_trace_setevent #TraceID, 10, 15, #ON -- EndTime
-- 12 = SQL:BatchCompleted
exec sp_trace_setevent #TraceID, 12, 1, #ON -- Textdata
exec sp_trace_setevent #TraceID, 12, 3, #ON -- DatabaseID
exec sp_trace_setevent #TraceID, 12, 12, #ON -- SPID
exec sp_trace_setevent #TraceID, 12, 13, #ON -- Duration
exec sp_trace_setevent #TraceID, 12, 14, #ON -- StartTime
exec sp_trace_setevent #TraceID, 12, 15, #ON -- EndTime
-- Filter for duration [column 13] greater than [operation 2] 10 seconds (= 10,000ms)
declare #duration bigint
set #duration = 10000
exec sp_trace_setfilter #TraceID, 13, 0, 2, #duration
You can find the ID for each trace-event, columns, etc from Books Online; just search for the sp_trace_create, sp_trace_setevent and sp_trace_setfiler sprocs. You can then control the trace as follows:
exec sp_trace_setstatus 15, 0 -- Stop the trace
exec sp_trace_setstatus 15, 1 -- Start the trace
exec sp_trace_setstatus 15, 2 -- Close the trace file and delete the trace settings
...where '15' is the trace ID (as reported by sp_trace_create, which the first script kicks out, above).
You can check to see what traces are running with:
select * from ::fn_trace_getinfo(default)
The only thing I will say in caution -- I do not know how much load this will put on your system; it will add some, but how big that "some" is probably depends how busy your server is.
I give my credit to all answer before me here.
This script show how to find top 'slowest' 20 queries that affect your SQL
select top 20 dest.text, deqs.execution_count, deqs.total_elapsed_time, deqs.total_worker_time,
(deqs.total_elapsed_time / deqs.execution_count) as 'avg_elapse_time',
(deqs.total_worker_time / deqs.execution_count) as 'avg_worker_time'
from sys.dm_exec_query_stats as deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) as dest
where deqs. last_execution_time >= '2021-09-27 16:00' /* YOUR DATE AND TIME HERE*/
order by 'avg_elapse_time' desc
SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC
This should show you the time and date of when a query was ran
I use the below query for tracing application activity on a SQL server that does not have trace profiler enabled.
The method uses Query Store (SQL Server 2016+) instead of the DMV's. This gives better ability to look into historical data, as well as faster lookups.
It is very efficient to capture short-running queries that can't be captured by sp_who/sp_whoisactive.
/* Adjust script to your needs.
Run full script (F5) -> Interact with UI -> Run full script again (F5)
Output will contain the queries completed in that timeframe.
*/
/* Requires Query Store to be enabled:
ALTER DATABASE <db> SET QUERY_STORE = ON
ALTER DATABASE <db> SET QUERY_STORE (OPERATION_MODE = READ_WRITE, MAX_STORAGE_SIZE_MB = 100000)
*/
USE <db> /* Select your DB */

If you want an history for the queries you executed through SMSS.
You may want to try SSMSPlus.

This feature does not exists out of the box in SSMS.
You'll need SSMS 18 or newer.

The SQL query below can show simple query logs:
SELECT last_execution_time, text
FROM sys.dm_exec_query_stats stats
CROSS APPLY sys.dm_exec_sql_text(stats.sql_handle)
ORDER BY last_execution_time
This is how it looks like below:
And, the SQL query below can show simple transaction query logs:
SELECT Operation, [Begin Time], [End Time]
FROM fn_dblog(NULL,NULL)
This is how it looks like below:
In addition, but I don't know the SQL query to show both simple query logs and simple transaction query logs together.
you can use "Automatically generate script on every save", if you are using management studio.
This is not certainly logging.
Check if useful for you.. ;)
If the queries you are interested in are dynamic queries that fail intermittently, you could log the SQL and the datetime and user in a table at the time the dynamic statement is created. It would be done on a case-by case basis though as it requires specific programming to happen and it takes a littel extra processing time, so do it only for those few queries you are most concerned about. But having a log of the specific statements executed can really help when you are trying to find out why it fails once a month only. Dynamic queries are hard to thoroughly test and sometimes you get one specific input value that just won't work and doing this logging at the time the SQL is created is often the best way to see what specifically wasn in the sql that was built.
A slightly out-of-the-box method would be to script up a solution in AutoHotKey. I use this, and it's not perfect, but works and is free. Essentially, this script assigns a hotkey to CTRL+SHIFT+R which will copy the selected SQL in SSMS (CTRL+C), save off a datestamp SQL file, and then execute the highlighted query (F5). If you aren't used to AHK scripts, the leading semicolon is a comment.
;CTRL+SHIFT+R to run a query that is first saved off
^+r::
;Copy
Send, ^c
; Set variables
EnvGet, HomeDir, USERPROFILE
FormatTime, DateString,,yyyyMMdd
FormatTime, TimeString,,hhmmss
; Make a spot to save the clipboard
FileCreateDir %HomeDir%\Documents\sqlhist\%DateString%
FileAppend, %Clipboard%, %HomeDir%\Documents\sqlhist\%DateString%\%TimeString%.sql
; execute the query
Send, {f5}
Return
The biggest limitations are that this script won't work if you click "Execute" rather than use the keyboard shortcut, and this script won't save off the whole file - just the selected text. But, you could always modify the script to execute the query, and then select all (CTRL+A) before the copy/save.
Using a modern editor with "find in files" features will let you search your SQL history. You could even get fancy and scrape your files into a SQLite3 database to query your queries.
