Illegal assignment from List<AggregateResult> to List<AggregateResult> #2763
eq-dsolari commented Nov 25, 2020
| The Apex Language server shows an AggregateResult type returned by a SOQL statement and then assigned to a List as an illegal assignment. From the Apex Developer documentation this is the intended use. An AggregateResult returned from a SOQL statement can be assigned to a collection of type: AggregateResult. I receive a warning in the Problems output in Visual Studio Code

| Thanks for logging this issue . I haven't been able to repro it using the code sample you provided (screenshot below). Can you provide a sample class/trigger where you are consistently seeing this behavior ? I think it might be an issue that's specific to a certain pattern I haven't been using while trying to repro this. Also, could you copy/paste the stack traces from the Output panel for ?

Sorry, something went wrong.

Sharing my it experience, using aggregateresult in salesforce.
The aggregate functions COUNT(fieldname) , COUNT_DISTINCT() , SUM() , AVG() , MIN() and MAX() in SOQL return an AggregateResult object or a List of AggregateResult objects. We can use aggregate functions result in apex by using AggregateResult object.
Here is an example to use AggregateResult in Salesforce. In below example I’m using COUNT(fieldname) aggregate function in SOQL to show Account record respective number of Contacts.

Illegal assignment from list to list exception in salesforce.
We cannot create a class with the names Account, Contact, Opportunity, etc. These are Standard object names. They are reserved keywords in Salesforce. So, you cannot use reserved keywords for your class names.

Illegal assignment from List<> to List<>
At line no. 7 I got "Illegal assignment from List to List" querry. But When I replace Quote sObject to Account then it works fine how?
You likely have a class or variable named "Quote", which is causing the problem, due to Name Shadowing . Use Schema.Quote instead:
You may want to refactor the Quote class; it's not ideal to use names that match standard objects, like Account and Quote, or standard libraries, like Test or Math.

You can't assign, the types are incompatible. You can use the map constructor that takes a list as argument
or if you have existing map - you can call putAll on it.

Since Apex is a case-insensitive language, the compiler sees this as the same as the built-in class AggregateResult. The SOQL query is known to return a List<AggregateResult>, as in the built-in class, but your local variable results is being read as a List<Aggregateresult>, as in the class you're writing here. Since those are different types ...

List<AggregateResult> so your code needs to be: List<AggregateResult> aggregates = [...]; (Adding the GROUP BY turns the query into an aggregate query.) See e.g. Working with SOQL Aggregate Functions for examples of how to get the result values from the AggregateResult object.
AggregateResult is a read-only sObject and is only used for query results. Aggregate functions become a more powerful tool to generate reports when you use them with a GROUP BY clause. For example, you could find the average Amount for all your opportunities by campaign. AggregateResult[] groupedResults. = [SELECT CampaignId, AVG(Amount) FROM ...

You'd replace your last line with this code: Map<Id, Case> casesById = new Map<Id, Case>([SELECT Id, Subject FROM Case]); List<Id> casIds = new List<Id>(casesById.keySet()); This would get you a Map of the Cases, keyed on their Id as well as a List of the Case Ids.

AggregateResult. A read-only SObject that returns query results only if a query call contains an aggregate function, such as MAX (). Results are returned in AggregateResult only if a query () or queryMore () call includes the aggregate function. If the call doesn't contain an aggregate function, the results are returned in the QueryResult SObject.
