I am trying to figure out why the same query is not valid in both a Log Analytics and Application Insights workspace.
I've been working on creating a cross-resource query and when I write the syntax in Log Analytics it has a syntax error around the workspace operator. It is successful when I do the same thing in an Application Insights query.
The query looks like this:
union
workspace("DefaultWorkspace-b432aa91-rrrr-qqqq-zzzz-aabbba7e8f42-WUS2").SecurityEvent
,workspace("DefaultWorkspace-fca02198a-aaaa-eeee-cccc-aaad9fbf7302-EUS").SecurityEvent
| count
Since in both workspaces it references other workspaces, I would think it would be portable if queried under the same tenant (which I am). In Azure Log Analytics it gives me the error:
Unknown function: 'workspace'.
I am running these in the Azure portal at the moment.
Can you try adding a space after the comma? This query is working for my own workspaces.
union
workspace("DefaultWorkspace-b432aa91-rrrr-qqqq-zzzz-aabbba7e8f42-WUS2").SecurityEvent
, workspace("DefaultWorkspace-fca02198a-aaaa-eeee-cccc-aaad9fbf7302-EUS").SecurityEvent
| count
This is not a direct answer, but suggestions.
As far as I know, only if the query missing table name, then it will cause the error "Unknown function: 'workspace'.". Like below:
So first, make sure in your query, you are adding table name after workspace("xxx"). I notice that in your query, you're using the correct syntax, but just want to make sure the table name is there.
Second, if you're adding table name after workspace("xxx"), and still get this error. You can try just use the query below to check if the workspace("xxx") works:
workspace("adsmit-test").Heartbeat
| count
Please feel free to let me know if you still have the issue.
I tried the same statement 2 weeks later in both an Application Insights and Log Analytics and it works in both.
I am running a following AEM Query SQL2 on CRXDE and it is successfully returning me nodes as per following given screenshot.
But I need data like column wise (jcr properties) like SQL table. Can anyone help me if it is possible.
You can't do this with CRXDE. It shows only the path of the most outer node, even if the query has multiple columns. This is especially limiting, if your query uses joins.
In your case I would recommend the Query Builder. It has a totally different syntax, but the JSON or XML result contains all data you need.
I don't know other tools. As AEM developer I usually write a quick & dirty servlet, and let it run on my local instance (with production content)
Query Builder Debugger

In your case especially see: Refining What Is Returned
You will find much more with Google, as the Query Builder is pretty old in AEM/CQ.
I'm struggling to make a (not so) complex query in firebase cloud firestore.
I simply need to get all docs where the id field == a given id.
Then order the results by their date and limit to 10 results.
So this is my current situation
db.firestore().collection('comments')
.where("postId",'==',idOfThePost)
.orderBy('date','asc').limit(10).get().then( snapshot => {
//Nothing happens and the request wasn't even been executed
})
I can get the result only if i don't use the orderBy query but i have to process this sorting for the needs of my application.
Someone has an idea to help me to fix this ?
thanks
You can do this by creating an Index in the firestore.
The first field of the index should be the equality field and the second field of the index should be the order by field.
Given your problem, you would need the following index:
first field: postId, 'asc'
second field: date, 'asc'
Please check the doc. It says
However, if you have a filter with a range comparison (<, <=, >, >=), your first ordering must be on the same field
you can try this code
db.firestore().collection('comments')
.where("postId",'==',idOfThePost)
.orderBy('postId')
.orderBy('date','asc').limit(10).get().then( snapshot => {
.....
})
My Workaround
If you're googling this you've probably realized it can't be done traditionally. Depending on your problem though there may be some viable workarounds, I just finished creating this one.
Scenario
We have an app that has posts that appear in a feed (kind of like Reddit), each post has an algorithmic score 'score' and we needed a way to get the 'top posts' from 12-24 hours ago. Trying to query sorted by 'score' where timestamp uses > and < to build the 12-24 hour ago range fails since Firebase doesn't allow multiple conditional querying or single conditional querying with an descending sort on another field.
Solution
What we ended up doing is using a second field that was an array since you can compound queries for array-contains and descending. At the time a post was made we knew the current hour, suppose it was hour 10000 since the server epoch (i.e. floor(serverTime/60.0/60.0)). We would create an array called arrayOfHoursWhenPostIsTwelveToTwentyFourHoursOld and in that array we would populate the following values:
int hourOffset = 12;
while (hourOffset <= 24) {
[arrayOfHoursWhenPostIsTwelveToTwentyFourHoursOld addObject:#(currentHour+hourOffset)];
hourOffset++;
}
Then, when making the post we would store that array under the field hoursWhenPostIsTwelveToTwentyFourHoursOld
THEN, if it had been, say, 13 hours since the post was made (the post was made at hour 10000) then the current hour would be 10013, so we could use the array-contains query to see if our array contained the value 10013 while also sorting by algorithm score at the same time
Like so:
FIRFirestore *firestore = [Server sharedFirestore];
FIRCollectionReference *collection = [firestore collectionWithPath:#"Posts"];
FIRQuery *query = [collection queryOrderedByField:#"postsAlgorithmScore" descending:YES];
query = [query queryWhereField:#"hoursWhenPostIsTwelveToTwentyFourHoursOld" arrayContains:#(currentHour)];
query = [query queryLimitedTo:numberToLoad];
Almost Done
The above code will not run properly at first since it is using a compound index query, so we had to create a compound index query in firebase, the easiest way to do this is just run the query then look at the error in the logs and firebase SDK will generate a link for you that you can navigate to and it will auto-generate the compound index for your database for you, otherwise you can navigate to firebase>database>index>compound>new and build it yourself using hoursWhenTwelveToTwentyFourHoursOld: Arrays, score: Descending
Enjoy!
same here, it is weird why can't. below is another sample. can't get the result. Hoping firebase can reply about this and update the document.
dbFireStore.collection('room').where('user_id.'+global.obj_user.user_id,'==',true).orderBy('last_update').get().then((qs)=>{
console.log(qs);
});
using other work-around solution is javascript array and array.sort()
I ran into the same issue yesterday on Android. The Callback was just not called. Today I suddenly got an error message. FAILED_PRECONDITION: The query requires an index. It even contains a URL in the error message to generate that index with one click.
It seems that if you want to use orderBy on your data, you need to create an index for that field. The index also needs to be in the correct order (DESC, ASC).
As per firestore document,
If you attempt a compound query with a range clause that doesn't map to an existing index, you receive an error. The error message includes a direct link to create the missing index in the Firebase console.
So just click that link you get in Logcat, it will be redirected to create index page, just create index. It will take some time. after enabling composite index, you will get the result as your requested query.
Stumbled across this looking for help when i found that using the orderBy function didnt work and the documentation still says it does not support it. A bit weird and unclear to be honest, because it does support it so long as you index your Firestore database. For example, this query now works fine for me having set up indexing:
const q = query(docRef, where("category", "==", 'Main'), orderBy('title', 'asc')
Indexing in Firestore
Console Log that even gives you the url to automatically create the index if you try and run with the above command.
Maybe I am missing something, or a later version of Firebase (I am using v9) simply does support it.
I have title search with Lucene .net and facing problem with LIKE clause search.
I have tried below terms but it is matching whole word.
query.Add(new TermQuery(new Term("title", word.ToLower())), BooleanClause.Occur.MUST);
Also tried
query.Add(new TermQuery(new Term("title", word.ToLower())), BooleanClause.Occur.SHOULD);
Any idea how to apply LIKE clause?
I would guess you are probably looking for either Prefix or Wildcard queries.
In general, I'd recommend getting some level of understanding of the instantiable subclasses of Query, listed here.
I'm querying the facebook feeds to get the latest feeds. I'm using the FB api:
55xxxxx/feed?since=1323269266&date_format=U&limit=5
The since date is taken from the previous api call first object create_date. Now the problem is that if the Group/News (id :55xxxxx) the first object's create_date is still 1323269266. It will give me again the 5 feeds. But I would like it to give me any new feeds after 1323269266. Any idea how?
Try a combination of since and until parameters rather than just since.
