Just this morning when trying to view the Data Explorer UI for an Azure Cosmos DB table the window is totally blank and I see no rows (the table should not be empty). The only connection to this table is a Python script that pushes in simple rows with only a few variables however this has also stopped working just this morning.
I am still able to connect to the table service properly and I've even been able to create a new table through my Python script. However, as soon as I call table_service.insert_or_replace_entity('traps', task) ('traps' is the name of my table and task is the row I'm trying to push up) I receive back an HTTP Error 400. The request URL is invalid.
For reference, my connection in Python is as follows where Account_Name = my personal account name and Account_Key = my personal account key.
table_service = TableService(connection_string="DefaultEndpointsProtocol=https;AccountName=Account_Name;AccountKey=Account_Key;TableEndpoint=https://Account_Name.table.cosmosdb.azure.com:443/;")
for i in list(range(0,len(times))):
print(len(tags))
print(len(times))
print(len(locations))
task = {'PartitionKey': '1', 'RowKey': '{}'.format(tags[i]),'Date_Time' : '{}'.format(times[i]), 'Location' : '{}'.format(locations[i])}
table_service.insert_or_replace_entity('traps', task)
UPDATE
In reference to the HTTP Error 400 I discovered that I was trying to push a \n at the end of each of the tags string (i.e. tags[0] = 'ab123\n'). Stripping out the \n has resolved the HTTP 400 error but I am now receiving The specified resource does not exist. message when I attempt to upload which makes more sense as at why my Data Explorer is blank. I have tried uploading to a new table but its the same thing.
Second Update
Silly mistake on resource not found error was that my table is called "Traps" not "traps". Data appears to be uploading correctly now on the API side. However, the table is still not displaying at all in the data explorer page of the Azure portal. If anyone has insight on this it would be appreciated because the explorer is super helpful while we are still in development.
Third Update
I am able to connect to the table/database through Python and query data effectively. It all seems to be in there and up to date. The only thing I'm left unsure about is why the Data Explorer is not displaying properly. Aside from that, my recommendation is to obviously check your capital letters (my usual mistake haha) and DO NOT try to push up line feeds (\n) in the task/payload.
Want to provide an official update and response to your issue. This issue is being Hotfixed with an ETA rolled out by Monday (09/24/2018).

We are having problem on a live production system.
One of the nodes stopped working properly (because of problems with network file system on which is it hosted) and that happened while the channel staging process was in progress.
Because of that really bad timing, the staging process remained unfinished and all locked resources remained that way which prevented editing products or catalogs on live system.
1st solution we have tried is restarting servers node by node, that didn't help.
2nd solution we tried executing SQLs mentioned in this support article:
https://support.intershop.com/kb/index.php/Display/2350K6
The exact SQLs we have executed are below, first one is for deleting from RESOURCELOCK table:
DELETE FROM RESOURCELOCK rl WHERE rl.LOCKID IN (SELECT
resourcelock.lockid
FROM
isresource ,
domaininformation resourcedomain,
process,
basiccredentials ,
domaininformation userdomain,
resourcelock ,
isresource_av
WHERE (
(isresource.domainid = resourcedomain.domainid)
AND (isresource.resourceownerid = process.uuid)
AND (resourcelock.lockid = isresource.uuid)
AND (process.userid = basiccredentials.basicprofileid(+))
AND (basiccredentials.domainid = userdomain.domainid(+))
AND (isresource_av.ownerid(+) = isresource.uuid)
AND (isresource.resourceownerid is not null)
AND (isresource_av.name(+) = 'locknestinglevel')
AND (process.name = 'StagingProcess')
));
And another one for ISRESOURCE table:
UPDATE isresource
SET
resourceownerid=null,
lockexpirationdate=null,
lockcreationdate=null,
lockingthreadid=null
WHERE
RESOURCEOWNERID='QigK85q6scAAAAF9Pf9fHEwf'; //UUID of StagingProcess
Now this has somewhat helped as it allowed for single products to be staged, but here are still two problems remaining:
Products can't be manually locked on live system for editing, when lock icon is clicked the page refreshes but it looks like it is still unlocked, but records are created for each product which is clicked on in ISRESOURCE table altough they are incomplete (the is no RESOURCEOWNERID, lock creation date, or lock expiration date), this can be seen below:
Also processes are tried to be created for product locking but they are all failing or running without end date as can be seen here:
Now for the second problem:
The channel staging cannot be started and it fails with message:
ERROR - Could not lock resources for process 'StagingProcess': Error finding resource lock with lockid: .0kK_SlyFFUAAAFlhGJujvESnull
That resource is MARKETING_Promotion resource:
Both problems started occuring after running above mentioned SQLs and it seems they are related, any advice on how to resolve this situation would be helpfull.
The first SQL that I posted shouldn't have been run:
DELETE FROM RESOURCELOCK rl WHERE rl.LOCKID IN....
The fix was to restore deleted resource locks and just set the lock fields in ISRESOURCE table to null with the second SQL:
UPDATE isresource
SET
resourceownerid=null,
lockexpirationdate=null,
lockcreationdate=null,
lockingthreadid=null
WHERE
RESOURCEOWNERID='QigK85q6scAAAAF9Pf9fHEwf'; //UUID of StagingProcess
We have a Xamarin Forms app.
We have a few existing users which had been using the app since last year where the database file name is MyAppName.db
Our new app strategy requires us to include the .db (Sqlite) along with the app to ensure we can include persistent information and does not require internet when you install the app, meaning we hope to overwrite the db file for existing users.
After we publish this new change where the database file is now MyNewDbFile.db, our users complain that they do not see any data, the app does not crash tough.
We capture error reports and we can see a common error in the our tool stating about "row value missused", a quick search indicates the value are not present and so the "SELECT * FROM TABLE WHERE COLUMNAME" query does not work causing the exception.
We can confirm we are using
Xamarin.Forms version 4.5.x
sqlite-net-sqlcipher version 1.6.292
We do not have any complex logic and cannot see a very specific reason causing this as this is not produced when we test our apps from the Alpha channel or the TestFlight.
We investigated the heart of the problem and can confirm that the troublemaker is the device Culture information.
We have been testing with English as the device language, however the minute the app is used by folks with any other language except English the query causes exception.
We make use of the Xamarin Essentials library to get device location (which is optional).
The latitude and longitude returned are culture specific.
So if you are using a Spanish language on device, the format for the Latitude and Longitude information is a , (comma) and NOT a . (dot).
That is, a Latitude value is something similar to 77.1234
where it is separated by a . (dot)
However for users with different region settings on device, the format would change to
77,1234 as value where it is separated by a , (comma).
The query requires us to have the values as string and that when not separated by a . (dot) fails to execute:
Query:
if (deviceLocation != null)
queryBuilder.Append($" ORDER BY((Latitude - {deviceLocation.Latitude})*(Latitude - {deviceLocation.Latitude})) +((Longitude - {deviceLocation.Longitude})*(Longitude - {deviceLocation.Longitude})) ASC");
Where the deviceLocation object is of type Xamarin.Essentials.Location which has double Latitude and Longitude values but when used as a string or even if you explicitly do deviceLocation.Latitude.ToString(), it would return the formatted values as per the device CultureInfo.
We can confirm that the problem is due to a mismatch of the format type and causing the query to throw an exception and in return making the experience as if there is no data.
I connected to clickhouse with tableau.
A query like this
select * from table_name limit 1
returns fields of the table, even though it should return raws.
image
If I try
select subs_key from table name limit 1
And click preview results
preview results
I get the error from above(except cnt is replaced with subs_key or whatever field I try to select)
How can I actually view table data?
Edit
There is a connection to the db, but no table is shown in available schemas.
EDIT 2
I managed to connect and get data from an oracle and mysql database, but while I am connected to click house, I can't see any data.
Don't quote me on this but I believe tableau has not official support for clickhouse, at least I could not find anything to contradict this, tons of people asking for it but nothing concrete.
There might some sort of beta integration that's not yet stable, hence you problem, but this is just blind guessing.
What I can recommend, if you really need a UI and can't just use the cl client is using tabix:
https://github.com/smi2/tabix.ui
Its fully open source for now and should be pretty easy and straight forward to learn, there might be the odd bits of Russian here and there, but I believe its getting debugged and translated at quite a good pace.
I get the same error message when I use DBeaver.
SQL Error [47]: ClickHouse exception, Code: 47, e.displayText() =
DB::Exception: Unknown identifier: default_type, e.what() = DB::Exception
If it's not a coincidence, then it's a JDBC driver bug.
When starting my program for the first time since the associated table has been deleted I get this error:
An exception of type 'Microsoft.WindowsAzure.Storage.StorageException' occurred in Microsoft.WindowsAzure.Storage.dll but was not handled in user code
Additional information: The remote server returned an error: (409) Conflict.
However if I refresh the crashed page the table will successfully create.
Here is the code just in case:
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
Microsoft.WindowsAzure.CloudConfigurationManager.
GetSetting("StorageConnectionString"));
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("tableTesting");
table.CreateIfNotExists();
I don't really understand how or why I'd be getting a conflict error if there's nothing there.
These errors appear elsewhere in my code as well when I'm working with blob containers, but I can't reproduce them as easily.
If you look at the status codes here: http://msdn.microsoft.com/en-us/library/azure/dd179438.aspx, you will notice that you get 409 error code in two scenarios:
Table already exists
Table is being deleted
If I understand correctly, table.CreateIfNotExists() only handles the 1st situation but not the 2nd one. Please check if that is not the case in your situation. One way to check this would be to see details of Storage Exception. Somewhere you should get the code which would match with the link I mentioned above.
Also one important thing to understand is that when you delete the table, it is actually marked for deletion and is actually deleted through a background process (much like garbage collection). If you try to create a table between these two steps, you will get the 2nd error.
I want to download HTML default report for a test run from Performance Center storage (using Rest API). Actually I need just summary.html file.
I was using the following steps in PC 11.5:
Request test scenarios:
http://{server:port}/qcbin/rest/domains/{domain}/projects/{project}/tests?fields=id,last-modified,name,owner&query={subtype-id[=PERFORMANCE-TEST]}&page-size=max
Let user choose the scenario (id) and request all its runs:
http://{server:port}/qcbin/rest/domains/{domain}/projects/{project}/runs?page-size=max&fields=id,owner,pc-start-time,duration,status,test-id&query={test-id[=234]}
Let user choose the run (id) and request Report (result entity):
http://{server:port}/qcbin/rest/domains/{domain}/projects/{project}/results?page-size=max&query={run-id[=123];name[=Reports]}&fields=id,name
Request "summary.html" file using file-id taken from previous step response:
http://{server:port}/qcbin/rest/domains/{domain}/projects/{project}/results/{file-id}/storage/report/summary.html
However it is not working with Performance Center 11.0. It fails at last step:
qccore.general-error
Not Found
I guess it is because the path of report was changed.
Can someone tell the path for summary.html for Performance Center 11.0?
I've been able to have a little bit of success with this. Rather than use the request you are using above I used the following:
http://{server:port}/qcbin/rest/domains/{domain}/projects/{project}/results/{file-id}/logical-storage/
This gave me a zip file, which contained the report inside it.
