I specify cluster+database+table
cluster("my_company_kusto.westeurope").database("events").table("CourierEvents")
| where OrderId == "C61F4D3A8B93975111EC8A629DDBCF0E"
but I get an error Please select a database to execute queries. until I select a table in the left menu and the scope appears on the top.
Is it possible to select the scope inside a request without selecting it in a left menu?
I assume that you are using one of the tools (Kusto Explorer or the Kusto Web explorer), if so the answer is yes. See the connection panel topic in the Kusto Explorer docs, and here is the applicable example:
#connect cluster('help').database('Samples')
StormEvents | count
Execute the first line, and it will set your context to the applicable cluster and database.

I am using the query band so the user can connect through the proxy user to the data pool in Teradata. Proxy users have full access to the table. How can I force the external users to see the selective columns? This is my query:
SET QUERY_BAND='PROXYUSER=TheAdmin; PROXYROLE=RoleOne;' FOR TRANSACTION;
SELECT Employee_Id, First_name, Last_Name FROM Project.myTest;
This query works, but the problem is if the external user use SELECT * FROM Project.myTest;
It returns the whole table. I want that user should not be able to see all the columns.
I don't want to use the view as I have a big DB and there I have to create so many views in each table.
Is there any way to do that? Will be great help and thanks in advance.
Can we insert data into kusto table using flow?
I tried to insert data into kusto table using .ingest inline command but it throws a bad request error shown below:
Bad request: Control commands (starting with a dot '.') cannot be served from the query endpoint unless they are .show control commands.\r\nPlease provide the following information when contacting the Kusto.
So can we insert data into kusto table using flow?
it is possible, you just need to choose the Run control command... action instead of the Run query ... option (as .ingest, like any other command that starts with a dot (.) is a control command, and not a query)
that said, using direct ingestion is not necessarily recommended for large scale - you can read more about why here: https://learn.microsoft.com/en-us/azure/kusto/management/data-ingestion/
Inline ingestion (push): A control command (.ingest inline) is sent to the engine, with the data to be ingested being a part of the command text itself. This method is primarily intended for ad-hoc testing purposes, and should not be used for production purposes.

Thank you it worked but we need to choose Chart Type as Html Table
I've been attempting to increase my knowledge and trying out some challenges. I've been going at this for a solid two weeks now finished most of the challenge but this one part remains. The error is shown below, what am i not understanding?
Error in sqlite query: update users set last_browser= 'mozilla' + select sql from sqlite_master'', last_time= '13-04-2019' where id = '14'
edited for clarity:
I'm trying a CTF challenge and I'm completely new to this kind of thing so I'm learning as I go. There is a login page with test credentials we can use for obtaining many of the flags. I have obtained most of the flags and this is the last one that remains.
After I login on the webapp with the provided test credentials, the following messages appear: this link
The question for the flag is "What value is hidden in the database table secret?"
So from the previous image, I have attempted to use sql injection to obtain value. This is done by using burp suite and attempting to inject through the user-agent.
I have gone through trying to use many variants of the injection attempt shown above. Im struggling to find out where I am going wrong, especially since the second single-quote is added automatically in the query. I've gone through the sqlite documentation and examples of sql injection, but I cannot sem to understand what I am doing wrong or how to get that to work.
A subquery such as select sql from sqlite_master should be enclosed in brackets.
So you'd want
update user set last_browser= 'mozilla' + (select sql from sqlite_master''), last_time= '13-04-2019' where id = '14';
Although I don't think that will achieve what you want, which isn't clear. A simple test results in :-
You may want a concatenation of the strings, so instead of + use ||. e.g.
update user set last_browser= 'mozilla' || (select sql from sqlite_master''), last_time= '13-04-2019' where id = '14';
In which case you'd get something like :-
Thanks for everyone's input, I've worked this out.
The sql query was set up like this:
update users set last_browser= '$user-agent', last_time= '$current_date' where id = '$id_of_user'
edited user-agent with burp suite to be:
Mozilla', last_browser=(select sql from sqlite_master where type='table' limit 0,1), last_time='13-04-2019
Iterated with that found all tables and columns and flags. Rather time consuming but could not find a way to optimise.
I am running the following query on Google BigQuery web interface, for data provided by Google Analytics:
SELECT *
FROM [dataset.table]
WHERE
hits.page.pagePath CONTAINS "my-fun-path"
I would like to save the results into a new table, however I am obtaining the following error message when using Flatten Results = False:
Error: Cannot query the cross product of repeated fields
customDimensions.value and hits.page.pagePath.
This answer implies that this should be possible: Is there a way to select nested records into a table?
Is there a workaround for the issue found?
Depending on what kind of filtering is acceptable to you, you may be able to work around this by switching to OMIT IF from WHERE. It will give different results, but, again, perhaps such different results are acceptable.
The following will remove entire hit record if (some) page inside of it meets criteria. Note two things here:
it uses OMIT hits IF, instead of more commonly used OMIT RECORD IF).
The condition is inverted, because OMIT IF is opposite of WHERE
The query is:
SELECT *
FROM [dataset.table]
OMIT hits IF EVERY(NOT hits.page.pagePath CONTAINS "my-fun-path")
Update: see the related thread, I am afraid this is no longer possible.
It would be possible to use NEST function and grouping by a field, but that's a long shot.
Using flatten call on the query:
SELECT *
FROM flatten([google.com:analytics-bigquery:LondonCycleHelmet.ga_sessions_20130910],customDimensions)
WHERE
hits.page.pagePath CONTAINS "m"
Thus in the web ui:
setting a destination table
allowing large results
and NO flatten results
does the job correctly and the produced table matches the original schema.
I know - it is old ask.
But now it can be achieved by just using standard SQL dialect instead of Legacy
#standardSQL
SELECT t.*
FROM `dataset.table` t, UNNEST(hits.page) as page
WHERE
page.pagePath CONTAINS "my-fun-path"
I have a question on creating running totals in MS Access 2010 similar to the one here:
Access 2010 - query showing running total for multiple records, dropping old record and adding new record on each line
However when I input the equivalent code from that thread I get an error saying that the database cannot be found (Access seems to think the table I have specified is the database name)
Here is the code from the original thread:-
SELECT hbep1.EmployeeID, hbep1.PayPeriodID,
(
SELECT Sum(hbep2.HoursUsed)
FROM Hours_by_Empl_PP hbep2
WHERE hbep2.EmployeeID=hbep1.EmployeeID
AND (hbep2.PayPeriodID Between hbep1.[PayPeriodID]-3
And hbep1.[PayPeriodID])
) AS Sum_of_Hours_last_4_PPs
FROM Hours_by_Empl_PP hbep1;
Here is the code I inputted into my query:-
SELECT
V4_Try.ID_NIS_INV_HDR,
V4_Try.ID_ITM,
V4_Try.RunTot3,
V4_Try.BomVsActQty,
DMin("RunTot3","V4_Try","[ID_Itm]=" & [ID_ITM]) AS IDItmMin,
DMax("RunTot3","V4_Try","[ID_Itm]=" & [ID_ITM]) AS IDItmMax,
(
SELECT Sum([V4_Try].[BomVsActQty])
FROM [V4_Try].[BomVsActQty]
WHERE [V4_Try].[ID_ITM]=[V4_Try].[ID_ITM]
AND (IDItmMax < IDItmMin)
) AS RunTot6
FROM V4_Try
ORDER BY V4_Try.ID_ITM, V4_Try.RunTot3;
One thing I notice is that the main query uses DMax() and DMin() to create some aliased columns
...
DMin("RunTot3","V4_Try","[ID_Itm]=" & [ID_ITM]) AS IDItmMin,
DMax("RunTot3","V4_Try","[ID_Itm]=" & [ID_ITM]) AS IDItmMax,
...
and then the subquery tries to use those aliases in its WHERE clause
(
SELECT ...
WHERE...
AND (IDItmMax < IDItmMin)
) AS RunTot6
I'm pretty sure that the subquery will have no knowledge of the column aliases in the "parent" query, so they may be the items that are unrecognized.
Start by running this query:
SELECT * FROM V4_Try;
Then develop for complexity. Build the nested query before anything else. When you know that runs, try adding your aliases, then the DMax() function, and so on. Isolate the point at which you have an error popping up.
This is the process to fix a query.
Oh, and please specify the precise error that is raised by Access. Also, if this is being run from VBA, please let us know because that affects your trouble-shooting.
