SQL Server Extended Events - find particular string in the syntax - sql-server

How can I check with SQL Server Extended Events if some string appears in the SQL query statement?
For example: I want to find all the queries that contain the string ord_id=4 from 12:00 to 15:00 every day.
How can I trace this with extended events?
Thanks,
Ohad

In the session wizard,select sql statement starting and in global fields ,select sql text like below
and in final screen, you can filter as shown in below screenshot

You can use this Query to read Extended Events
SELECT CONVERT(XML, event_data) XMLEventData FROM sys.fn_xe_file_target_read_file(N'PathForTheFile\*.xel', NULL, NULL, NULL)
if you write * this means read all files, if you know where to look you can write your file name instead of *
After this to make it easy to the eye use the Query below, you need to modify the query for your needs.
SELECT
xexml.value('(./action[#name="username"]/value)[1]', 'varchar(400)') as UserName
,xexml.value('(./action[#name="client_hostname"]/value)[1]', 'varchar(400)') as Client_Hostname
,xexml.value('(./action[#name="collect_system_time"]/value)[1]', 'datetime') as ProcessTime
,xexml.value('(./data[#name="statement"]/value)[1]', 'nvarchar(4000)') as SQLStatement
FROM
(
SELECT CONVERT(XML, event_data) XMLEventData FROM sys.fn_xe_file_target_read_file(N'PathOfYourFiles\*.xel', NULL, NULL, NULL) f
) AS EventTable
CROSS APPLY XMLEventData.nodes('/event') n (xexml)
WHERE cast(xexml.value('(./action[#name="collect_system_time"]/value)[1]', 'datetime')as time) between '12:00:00' and '15:00:00'
AND xexml.value('(./data[#name="statement"]/value)[1]', 'nvarchar(4000)') like '%ord_id=4%'

AND Infoneg.TipoNeg IS NULL
When I run it, I get 30 thousand rows and the columns that I get when performing the query are: ClientID, name. I would like it to be saved in an Excel file when I run it, I don't know if it's possible.
Another question, is it possible to create a variable that stores text?
I used CONCAT(), but the text being so long is a bit cumbersome, I don't know if there is any alternative.
If you can help me, I appreciate it.
To declare a variable
DECLARE #string VARCHAR(MAX)
SET #string = concat()
then insert whatever you are concatenating

Export SQL query data to Excel
I don't know if this is what you're looking for, but you can export the results to Excel like this:
In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.
You might give this a shot too:
INSERT INTO OPENROWSET
('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')
Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:
http://www.accelebrate.com/sql_training/ssis_2008_tutorial.htm
== Update #1 ==
To save the result as CSV file with column headers, one can follow the steps shown below:
Go to Tools->Options
Query Results->SQL Server->Results to Grid
Check “Include column headers when copying or saving results”
Click OK.
Note that the new settings won’t affect any existing Query tabs — you’ll need to open new ones and/or restart SSMS.

Find out when the last failover occurred in AlwaysOn availability groups

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 .

Sql Server - How do I get JSON nested value in my SQL Select statement

Environment: SQL Server 2014 and above
How do I access the email value in my JSON value with my SELECT statement?
select JSON_VALUE('[{"data":{"email":"test#email.com"}}]', '$.email') as test
Json support was only introduced in SQL Server 2016 - so with any prior version you would need to either use string manipulation code or simply parse the json outside of SQL Server (maybe using a CLR function)
For 2016 version or higher, you can use JSON_VALUE like this:
declare #json as varchar(100) = '[{"data":{"email":"test#email.com"}}]';
select JSON_VALUE(#json, '$[0].data.email') as test
For older versions - you might be able to get away with this, but if your json value does not contain an email property, you will get unexpected results:
select substring(string, start, charindex('"', string, start+1) - start) as test
from (
select #json as string, charindex('"email":"', #json) + 9 as start
) s
You can see a live demo on db<>fiddle
Another way. PatternSplitCM is great for stuff like this.
Extract a single Email value:
DECLARE #json as varchar(200) = '[{"data":{"email":"test#email.com"}}]';
SELECT f.Item
FROM dbo.patternsplitCM(#json,'[a-z0-9#.]') AS f
WHERE f.item LIKE '%[a-z]%#%.%[a-z]%'; -- Simple Email Check Pattern
Extracting all Email Addresses (if/when there are more):
DECLARE #json VARCHAR(200) = '[{"data":{"email":"test#email.com"},{"email2":"test2#email.net"}},{"data":{"MoreEmail":"test3#email.555whatever"}}]';
SELECT f.Item
FROM dbo.patternsplitCM(#json,'[a-z0-9#.]') AS f
WHERE f.item LIKE '%[a-z]%#%.%[a-z]%'; -- Simple Email Check Pattern
Returns:
Item
--------------------------
test#email.com
test2#email.net
test3#email.555whatever
Or... the get only the first Email address that appears:
SELECT TOP (1) f.Item
FROM dbo.patternsplitCM(#json,'[a-z0-9#.]') AS f
WHERE f.item LIKE '%[a-z]%#%.%[a-z]%' -- Simple Email Check Pattern
ORDER BY ROW_NUMBER() OVER (ORDER BY f.ItemNumber)
Nasty fast, super-simple. No cursors, loops or other bad stuff.
With v2014 there is no JSON support, but - if your real JSON is that simple - it is sometimes a good idea to use some replacements in order to transform the JSON to XML like here, which allows for the native XML methods:
DECLARE #YourJSON NVARCHAR(MAX)=N'[{"data":{"email":"test#email.com"}}]';
SELECT CAST(REPLACE(REPLACE(REPLACE(REPLACE(#YourJSON,'[{"','<'),'":{"',' '),'":"','="'),'}}]',' />') AS XML).value('(/data/#email)[1]','nvarchar(max)');
It can be done in two ways:
First, if your JSON data is between [ ] like in your question:
select JSON_VALUE('[{"data":{"email":"test#email.com"}}]','$[0].data.email' ) as test
And if your JSON data is not between [ ]:
select JSON_VALUE('{"data":{"email":"test#email.com"}}','$.data.email' ) as test
You can teste the code above here
Your query should be like this (SQL Server 2016):
DECLARE #json_string NVARCHAR(MAX) = 'your_json_value'
SELECT [key],value
FROM OPENJSON(#json_string, '$.email'))
UPDATE :
select JSON_VALUE(#json_string, '$[0].data.email') as test

Using T-SQL find the Stored Procedure associated to an SSRS Report

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.
SELECT
Ds.Name as Data_Source_Name,
C2.Name AS Data_Source_Reference_Name,
C.Name AS Dependent_Item_Name,
C.Path AS Dependent_Item_Path,
ds.*
FROM
ReportServer.dbo.DataSource AS DS
INNER JOIN
ReportServer.dbo.Catalog AS C ON DS.ItemID = C.ItemID
AND DS.Link IN (SELECT ItemID
FROM ReportServer.dbo.Catalog
WHERE Type = 5) --Type 5 identifies data sources
FULL OUTER JOIN
ReportServer.dbo.Catalog C2 ON DS.Link = C2.ItemID
WHERE
C2.Type = 5
AND c.name LIKE '%mkt%'
ORDER BY
C.Path, C2.Name ASC, C.Name ASC;
Please advise.
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.

BigQuery or SQL Server SPLIT query

I have searched around and can not find much on this topic. I have a table, that gets logging information. As a result the column I am interested in contains multiple values that I need to search against. The column is formatted in a php URL style. i.e.
/test/test.aspx?DS_Vendor=55039&DS_ProdVer=7.90.100.0&DS_ProdLang=EN&DS_Product=MTT&DS_OfficeBits=32
This makes all searches end up with really long regexes to get data. Then join statements to combine data.
Is there a way in BigQuery, or SQL Server that I can pull the information from that column and put it into new columns?
Example:
The information I would like extracted begins after the ?, and ends at &, The string can sometimes be longer, and contains additional headers.
Thanks,
Below is for BigQuery Standard SQL and addresses below aspect of your question
Is there a way in BigQuery, ... that I can pull the information from that column and put it into new columns?
#standardSQL
CREATE TEMP FUNCTION parseColumn(kv STRING, column_name STRING) AS (
IF(SPLIT(kv, '=')[OFFSET(0)]= column_name, SPLIT(kv, '=')[OFFSET(1)], NULL)
);
WITH `project.dataset.table` AS (
SELECT '/test/test.aspx?extra=abc&DS_Vendor=55039&DS_ProdVer=7.90.100.0&DS_ProdLang=EN&DS_Product=MTT&DS_OfficeBits=32' AS url UNION ALL
SELECT '/test/test.aspx?DS_Vendor=55192&DS_ProdVer=4.30.100.0&more=123&DS_ProdLang=DE&DS_Product=MTE&DS_OfficeBits=64'
)
SELECT
MIN(parseColumn(kv, 'DS_Vendor')) AS DS_Vendor,
MIN(parseColumn(kv, 'DS_ProdVer')) AS DS_ProdVer,
MIN(parseColumn(kv, 'DS_ProdLang')) AS DS_ProdLang,
MIN(parseColumn(kv, 'DS_Product')) AS DS_Product,
MIN(parseColumn(kv, 'DS_OfficeBits')) AS DS_OfficeBits
FROM `project.dataset.table`,
UNNEST(REGEXP_EXTRACT_ALL(url, r'[?&]([^?&]+)')) AS kv
GROUP BY url
with the result as below
Row DS_Vendor DS_ProdVer DS_ProdLang DS_Product DS_OfficeBits
1 55039 7.90.100.0 EN MTT 32
2 55192 4.30.100.0 DE MTE 64
Below is also addressed
The string can sometimes be longer, and contains additional headers.
One example using BigQuery (with standard SQL):
SELECT REGEXP_EXTRACT_ALL(url, r'[?&]([^?&]+)')
FROM (
SELECT '/test/test.aspx?DS_Vendor=55039&DS_ProdVer=7.90.100.0&DS_ProdLang=EN&DS_Product=MTT&DS_OfficeBits=32' AS url
)
This returns the parts of the URL as an ARRAY<STRING>. To go one step further, you can get back an ARRAY<STRUCT<key STRING, value STRING>> with a query of this form:
SELECT
ARRAY(
SELECT AS STRUCT
SPLIT(part, '=')[OFFSET(0)] AS key,
SPLIT(part, '=')[OFFSET(1)] AS value
FROM UNNEST(REGEXP_EXTRACT_ALL(url, r'[?&]([^?&]+)')) AS part
) AS keys_and_values
FROM (
SELECT '/test/test.aspx?DS_Vendor=55039&DS_ProdVer=7.90.100.0&DS_ProdLang=EN&DS_Product=MTT&DS_OfficeBits=32' AS url
)
...or with the keys and values as top-level columns:
SELECT
SPLIT(part, '=')[OFFSET(0)] AS key,
SPLIT(part, '=')[OFFSET(1)] AS value
FROM (
SELECT '/test/test.aspx?DS_Vendor=55039&DS_ProdVer=7.90.100.0&DS_ProdLang=EN&DS_Product=MTT&DS_OfficeBits=32' AS url
)
CROSS JOIN UNNEST(REGEXP_EXTRACT_ALL(url, r'[?&]([^?&]+)')) AS part
