I am using the clientAPI to query an index (Cards) in RavenDB so:
Dim cards = Raven.CurrentSession.Query(Of Cards)("Cards").ToArray()
This works well and returns all the documents, but how can I get the ID of the documents it returns?
Eystein,
for each of the returned cards, you do
Raven.CurrentSession.Advanced.GetDocumentId(card)

I have an API I am pinging which queries a cosmos db to return records.
I can filter on a simple string in my api call like so:
// return objects where '_Subject' field equals "filterTest"
string getUrl = $"...baseApiPath/?$filter=_Subject+eq+'filterTest'";
This is working perfectly.
But I cannot figure out the filter syntax to make my API query be based on ARRAY_CONTAINS.
// return objects where '_Attachments' field CONTAINS "945afd138aasdf545a2d1";
How would I do that? Is there a general reference for API filter syntax somewhere?
If you're asking about how to query, a query against a property with an array of values looks like this:
SELECT * FROM c WHERE ARRAY_CONTAINS(c._Attachments, "945afd138aasdf545a2d1")
Another example in this answer.
I was wondering if there is a way to use a select statement with a where clause similar to this way that does not seem to work for me in Ruby version 2.0/Rails 4.0 trying to retrieve a single record string value of a city where the building name is a certain name:
building_city = Building.select(:city).where(building_name: building).uniq
I have also tried:
building_city = Building.select(:city).where(building_name: building).distinct
Currently I have my code working like this:
building_city = Building.where(building_name: building).first
This grabs an entire Building object, and then I can call the city by doing a:
building_city.city
This works fine with what I am trying to achieve, but I was wondering if there is a smarter way to do this. Specifically, I was wondering if there is a way to grab only the string value of a city where the building name equals a certain building and store it into a variable?
Any help/advice is greatly appreciated! :)
Are you perhaps looking for pluck? Something like:
cities = Building.where(building_name: building).uniq.pluck(:city)
That will perform this SQL:
select distinct city from buildings where building_name = '...'
and give you the cities as an array of strings. You'll still get an array but a quick first call will take care of that if you're certain that there will only be one entry.
building_city = Building.select(:city, :building_name).where(building_name: building).uniq — you need to include the building_name
city = Building.where(building_name: building).pick(:city)
Rails 6 introduced pick method with works like where(..).pluck(..).first. Docs
I have a Linq Query made into a list called "ticket query"
I want to search ticket query for all the records that have specific data
I tried using FindAll() but it gives me an error
Argument matching parameter 'match' cannot convert from
'VB$AnonymousDelegate_1(Of JobPartForm,Nullable(Of Boolean))' to
'Predicate(Of JobPartForm)'.
I can't do the findall directly in the query because its being called at a separate time
is there another way to accomplish this, or am I using find all wrong?
ticketquery = (From ticket In dbContext.JobPartForm
Select ticket).ToList()
Dim formticket = ticketquery.FindAll(Function(f As JobPartForm) f.JobNum = ticketnum And f.FormNumber = formnum)
You can do the same using IQueryable<TSource>.Where method:
Dim formticket=dbContext.JobPartForm.Where((Function(f As JobPartForm) f.JobNum = ticketnum And f.FormNumber = formnum)).ToList();
The first thing is try to never call ToList extension method from a DbSet, that will load your entire table to memory, is really inefficient and more when you can filter your data on the server side.
Hello I have a problem with elasticsearch php api, elastica.
if I run this:
$elasticaQueryMatch= new Elastica\Query\Match();
$elasticaQueryMatch->setField('fax', "16147591649");
$elasticaResultSet = $elasticaIndex->search($elasticaQueryMatch);
var_dump($elasticaResultSet);
I get 7 results and the telephone number for all of the results is "16147591649"
Then if I run this:
$elasticaQueryMatch= new Elastica\Query\Match();
$elasticaQueryMatch->setField('telephone', "16147591649");
$elasticaResultSet = $elasticaIndex->search($elasticaQueryMatch);
var_dump($elasticaResultSet);
I get 0 results
Fixed it by creating a new index, changed my mapping and then rebuilt my index. It was the mapping and the analyzers for certain fields that were causing issues.
I am performing a search in which I have to get the 'ID' (field) of the last item stored in the sitecore/content/data/MyItem. The items stored in this folder are in 1000+ in number. I know Lucene search is by far efficient. I performed a Lucene Search to get the items based on the value like this:
using (IndexSearchContext searchContext = indx.CreateSearchContext())
{
var db = Sitecore.Context.Database;
CombinedQuery query = new CombinedQuery();
QueryBase catQuery = new FieldQuery("country", guidValueToSearch); //FieldName, FieldValue.
SearchHits results = searchContext.Search(catQuery); //Searching the content items by fields.
SearchResultCollection result = results.FetchResults(0, numOfArticles);
Here I am passing the guidValueToSearch for the items needs to be fetched for "country" field value. But I want to get the last item in the folder. How should I achieve this?
If you know you need the last childitem of /sitecore/content/data/MyItem, you could also use a more simple approach and get the parentItem and then retrieve the last child:
Item myItem = Sitecore.Context.Database.GetItem("/sitecore/content/data/MyItem");
Item lastItem = myItem.Children.Last();
The same could be done with Descendants instead of Children.
If you did want to implement it using search then have a look at this answer which explains how to extend the IndexSearchContext to have methods that accept a Lucene.Net.Search.Sort. You can then pass in the Sitecore.Search.BuiltinFields.Created or Sitecore.Search.BuiltinFields.Updated field (depending on what you are after).
