I have a chain of nodes, e.g.
{Name: 'X'}->{Name: 'Y'}->{Name: 'Z'}
and I'd like to create a string representing the path in cypher (I know I can do it client-side but I want to do it in a query) that would look like this:
'X->Y->Z'
is that feasible? I've investigated use of collect() and UNWIND, and have googled till I'm blue in the face
thoughts?
* Edit I *
as an addendum (and to make the problem more difficult) my query is going to return a collection of paths (a tree, a DAG), so I'll need to create a string for each of the paths in the tree
REDUCE is your friend here:
WITH reduce(s="",n in nodes(p) | s+n.name+"->") as str
RETURN substring(str,0,length(str)-2)
or if you want to save the extra operation
RETURN reduce(s=head(nodes(p)).name, n in tail(nodes(p)) | s+"->"+n.name)
or with APOC
RETURN apoc.text.join([n in nodes(p) | n.name],"->")

I'm trying to write a query that returns the vulnerabilities found by "Built-in Qualys vulnerability assessment" in log analytics.
It was all going smoothly I was getting the values from the properties Json and turning then into separated strings but I found out that some of the terms posses more than one value, and I need to get all of them in a single cell.
My query is like this right now
securityresources | where type =~ "microsoft.security/assessments/subassessments"
| extend assessmentKey=extract(#"(?i)providers/Microsoft.Security/assessments/([^/]*)", 1, id), IdAzure=tostring(properties.id)
| extend IdRecurso = tostring(properties.resourceDetails.id)
| extend NomeVulnerabilidade=tostring(properties.displayName),
Correcao=tostring(properties.remediation),
Categoria=tostring(properties.category),
Impacto=tostring(properties.impact),
Ameaca=tostring(properties.additionalData.threat),
severidade=tostring(properties.status.severity),
status=tostring(properties.status.code),
Referencia=tostring(properties.additionalData.vendorReferences[0].link),
CVE=tostring(properties.additionalData.cve[0].link)
| where assessmentKey == "1195afff-c881-495e-9bc5-1486211ae03f"
| where status == "Unhealthy"
| project IdRecurso, IdAzure, NomeVulnerabilidade, severidade, Categoria, CVE, Referencia, status, Impacto, Ameaca, Correcao
Ignore the awkward names of the columns, for they are in Portuguese.
As you can see in the "Referencia" and "CVE" columns, I'm able to extract the values from a specific index of the array, but I want all links of the whole array
Without sample input and expected output it's hard to understand what you need, so trying to guess here...
I think that summarize make_list(...) by ... will help you (see this to learn how to use make_list)
If this is not what you're looking for, please delete the question, and post a new one with minimal sample input (using datatable operator), and expected output, and we'll gladly help.
I am trying to create a search query for when a Public IP is assigned to a NIC, and then create an alert off that. I can find the part which identifies the assignment, but I need to use "inverted commas" within my search, but I can't...
My query:
AzureActivity
| where OperationName == "Microsoft.Network/networkInterfaces/write" and ActivityStatus == "Started"
| where Properties contains "<>"
Within that "contains", I need to use the following JSON pulled from the properties JSON (which I found doing a search without Properties Contains):
\"provisioningState\":\"Succeeded"\
However, I know I can't use "inverted commas" within an already inverted comma area. Is there a way to allow me to put that inside, perhaps with some sort of cancelling or bracketing?
You can use # for escaping - see here:
https://docs.loganalytics.io/docs/Language-Reference/Data-types/string
or, possibly better yet, you can use extractjson (or parsejson) functions
https://docs.loganalytics.io/docs/Language-Reference/Scalar-functions/extractjson()
I have found my solution, thanks to the links submitted by #Oleg Ananiev.
AzureActivity
| sort by TimeGenerated desc nulls last
| where OperationName == "Microsoft.Network/networkInterfaces/write" and ActivityStatus == "Started"
| where Properties contains '\\"provisioningState\\":\\"Succeeded\\"'
A better way to read to the nested property in JSON format using parse_json. For example if you would like to read to provisioningState property's value, simple do the following query
| where parse_json(Properties).provisioningState == 'Succeeded'
Please let me know if that helps!
In my feature I have:
* def loc = responseHeaders['location'][10]
* def id = loc.substring(loc.lastIndexOf('/') + 1)
And I would like to use id in scenario outline examples:
Scenario Outline: fkdfslqknfd
Given url 'foo.com'
And path <bar>
When method get
......
Examples:
|bar |
|(id)|
|"id"|
|'id'|
|id |> The last example is ok.
But instead of receiving 'foo.com/13' (assuming that id is 13) I have 'foo.com/id'. I tried with #, but it doesn't work. How I can replace this id? I need to test this id put in String format. Thanks
At least within JSON parameter, it was working for me
Examples:
| request_body |
| {username: '#(email)', password: '#(password)'} |
This is a known limitation of Cucumber, that the Examples cannot be dynamic. Refer to this last paragraph of the documentation: https://github.com/intuit/karate#the-karate-way
If you are really trying to loop over a feature with different values, again, refer to the above doc, and there are plenty of examples if you look around. Look at all the ones that start with call- here: https://github.com/intuit/karate/tree/master/karate-demo

i am implement my own advance search in alfresco. i need to read all files which related with particular category.
example:
if there is 20 file under geograpy, lucene query should read particular document under search key word "banana".
Further explanation -
I am using search.lib.js to search. I would like to analyze the result to find out to which category the documents belong to. For example I would like to know how many documents belong to the category under Languages and the subcategories. I experimented with the Classification API but I don't get the result I want. Any Idea how to go through the result to get the category name of each document?
is there any simple method like node.properties["cm:creator"]?
thanks
janaka
I think you should specify more your question:
Are you using cm:content or a customized content?
Are you going to search the keyword inside the content of the file? or are you going to search the keyword in a specific metadata(s)?
Do you want to create a webscript (java or javascript)?
One thing to take in consideration:
if you use +PATH:"cm:generalclassifiable/...." for the categorization in your lucene queries, the performance will be slow (following my experince)
You can use for example the next query to find all nodes at any depth below /cm:Languages:
var results = search.luceneSearch("+PATH:\"cm:generalclassifiable/cm:Languages//*\");
Take a look to this url: https://wiki.alfresco.com/wiki/Search#Path_Queries
Once you have all the elements, you can loop all, and get to which category below. Of course you need to create some counter per each category/subcategory:
for(i = 0; i < results.length; i++){
var node = results[i];
var categoryNodeRef = node.properties["cm:categories"];
var categoryDesc = categoryNodeRef.properties["cm:description"];
var categoryName = categoryNodeRef.properties["cm:name"];
}
This is not exactly the solution, but can be a useful idea to start.
Sorry if it's not what you're asking for, I have just arrived from my holidays.
I'm trying to generate a new SharePoint list item directly using SQL server. What's stopping me is damn tp_DirName column. I have no ideas how to create this value.
Just for instance, I have selected all tasks from AllUserData, and there are possible values for the column: 'MySite/Lists/Task', 'Lists/Task' and even 'MySite/Lists/List2'.
MySite is the FullUrl value from Webs table. I can obtain it. But what about 'Lists/Task' and '/Lists/List2'? Where they are stored?
If try to avoid SQL context, I can formulate it the following way: what is the object, that has such attribute as '/Lists/List2'? Where can I set it up in GUI?
Just a FYI. It is VERY not supported to try and write directly to SharePoint's SQL Tables. You should really try and write something that utilizes the SharePoint Object Model. Writing to the SharePoint database directly mean Microsoft will not support the environment.
I've discovered, that [AllDocs] table, in contrast to its title, contains information about "directories", that can be used to generate tp_DirName. At least, I've found "List2" and "Task" entries in [AllDocs].[tp_Leaf] column.
So the solution looks like this -- concatenate the following 2 components to get tp_DirName:
[Webs].[FullUrl] for the web, containing list, containing item.
[AllDocs].[tp_Leaf] for the list, containing item.
Concatenate the following 2 components to get tp_Leaf for an item:
(Item count in the list) + 1
'_.000'
Regards,
Well, my previous answer was not very useful, though it had a key to the magic. Now I have a really useful one.
Whatever they said, M$ is very liberal to the MOSS DB hackers. At least they provide the following documents:
http://msdn.microsoft.com/en-us/library/dd304112(PROT.13).aspx
http://msdn.microsoft.com/en-us/library/dd358577(v=PROT.13).aspx
Read? Then, you know that all folders are listed in the [AllDocs] table with '1' in the 'Type' column.
Now, let's look at 'tp_RootFolder' column in AllLists. It looks like a folder id, doesn't it? So, just SELECT the single row from the [AllDocs], where Id = tp_RootFolder and Type = 1. Then, concatenate DirName + LeafName, and you will know, what the 'tp_DirName' value for a newly generated item in the list should be. That looks like a solid rock solution.
Now about tp_LeafName for the new items. Before, I wrote that the answer is (Item count in the list) + 1 + '_.000', that corresponds to the following query:
DECLARE #itemscount int;
SELECT #itemscount = COUNT(*) FROM [dbo].[AllUserData] WHERE [tp_ListId] = '...my list id...';
INSERT INTO [AllUserData] (tp_LeafName, ...) VALUES(CAST(#itemscount + 1 AS NVARCHAR(255)) + '_.000', ...)
Thus, I have to say I'm not sure that it works always. For items - yes, but for docs... I'll inquire into the question. Leave a comment if you want to read a report.
Hehe, there is a stored procedure named proc_AddListItem. I was almost right. MS people do the same, but instead of (count + 1) they use just... tp_ID :)
Anyway, now I know THE SINGLE RIGHT answer: I have to call proc_AddListItem.
UPDATE: Don't forget to present the data from the [AllUserData] table as a new item in [AllDocs] (just insert id and leafname, see how SP does it itself).
