I'm trying to get a list from my query, but it don't work and I'm getting stuck.
There is my query :
SELECT Id, Type, Status, CreatedDate, Product2__r.Name FROM Case
I've also tried without the __r suffix but it don't work too.
There is a lookup relationship from Case to Product.
Thanks in advance!

I have a problem on the query on my test class. I have put AssetId__r.Product2Id on the 1st query, and put Product2Id in the Asset query. but still the error persist. as the error says it needs Asset.Product2 which is an SObject , not a field and I am lost on how to fix this error. does anyone encounter this error before? please I need your help.
would be easier if you'd post the actual query.
You probably have something like that in your code:
String name = myObject.AssetId__r.Product2.Name;
but the query SELECT AssetId__r.Product2Id, ... FROM MyTable WHERE ...
So what you can change is put more product fields in the query. You can go up to 5 dots "up".
SELECT AssetId__r.Product2.Id,
AssetId__r.Product2.Name,
AssetId__r.Product2.ProductCode
FROM myObject
WHERE ...
It will work and then Apex that uses it can treat AssetId__r.Product2 as a normal Product2 object, as if it was queried separately. It'll have Id, Name, ProductCode fields set.
The query is also "safe". If AssetId__c is null or Product2Id is null - it'll still execute OK. You'll have to do null checks in Apex (or in query's WHERE clause)
So I am generally able to query the relationships but I do not have the access to this object in object manager, so what should be the query to access accountId from ContentDocumentLink object when I know LinkedEntity is a case.
My Code:
List<ContentDocumentLink> case_file_links=
[
SELECT Id,ContentDocumentId,LinkedEntityId.AccountId,ShareType
FROM ContentDocumentLink
WHERE Id IN: case_file_link_Ids
];
Error:
SELECT Id,ContentDocumentId,LinkedEntityId.AccountId,ShareType
^
ERROR at Row:2:Column:45
Didn't understand relationship 'LinkedEntityId' in field path. If you..
LinkedEntityId is a weird mutant lookup to many tables, any table that supports File upload. Official name is "polymorphic lookup".
Maybe you worked with Tasks before, they have similar fields. WhatId can point to Account, Case, Opportunity plus many custom objects. and WhoId points to User/Contact/Lead.
So it's a lookup to "something". It's not guaranteed it's to Cases so at compile time SF can't just blindly accept AccountId. What if the field is not there.
You might have to use TYPEOF in SOQL.
SELECT Id, ContentDocumentId, ShareType,
TYPEOF LinkedEntity WHEN Case THEN CaseNumber, Subject, AccountId END
FROM ContentDocumentLink
WHERE Id IN ('06A7a000001VafmEAC', '06A7a000001VafnEAC')
Developer Console is too stupid to display it properly but workbench should manage
In Apex you'll need an instanceof to check and cast the LinkedEntity to right sObject... or use the generic sObj.get('AccountId') and if it's not there it'll return null?
If this sounds like too much hassle - you can always split it into 2 queries.
Query just SELECT Id, ContentDocumentId, LinkedEntityId, ShareType FROM ContentDocumentLink
Loop through results, collect LinkedEntityId into a helper Set<Id>.
Map<Id, Case> cases = new Map<Id, Case>([SELECT Id, AccountId FROM Case WHERE Id IN :mySet]);
I want to show accounts and contacts data of a particular case in a form. how can i query the same using soql query in salesforce.
I have a custom object named Work_Order__c which is having a master-detail relationship with CASE object.
I am trying to write a below mentioned query, but the inner query is giving error.
select Id,Case__r.CaseNumber,Case__r.Description,Name,
Status__c,Priority__c,Description__c,City__c,Street__c,Zip__c,
(select Case__r.Account.Name, Case__r.Contact.Name from Work_Orders__r)
from Work_Order__c where Id = 'a024B0000025L6G'
The inner query is giving you an error because Work_Orders__r isn't a table. It is syntactic-sugar that gives you the list of all Work_Orders that are associated with a Case.
What you probably want is something like this:
SELECT Id,Name,Status__c,Priority__c,Description__c,City__c, Street__c,Zip__c,
Case__r.CaseNumber, Case__r.Description,
Case__r.Contact.FirstName,Case__r.Contact.LastName,Case__r.Contact.<Other_Contact_Fields>,
Case__r.Account.Name, Case__r.Account.<Other_Account_Fields>
FROM Work_Order__c
WHERE Id = 'a024B0000025L6G';
My other recommendations is to avoid hard coding your Id.
I am looking for select custom fields of "who" object using SOQL in slaesforce:
As I am testing following SOQL, its working fine.
Select t.Who.FirstName, t.Status From Task t Where t.ActivityDate = TODAY AND t.Who.Type = 'Lead'
but while add any custom field of lead object(who object here) in select statement, as mentioned following query, its give error as
No such column 'LeadExtraInfo__c' on entity 'Name'.
even LeadExtraInfo field exist into Lead object
Select t.Who.FirstName, t.Who.LeadExtraInfo__c t.ActivityDate From Task t Where t.ActivityDate = YESTERDAY AND t.Who.Type = 'Lead'
The Who and What relationships on Task are not normal relationships -- they are polymorphic. This means that they can refer to different types of objects.
In the case of Who, it can refer to a Lead or a Contact. As such, you can only get to a limited subset of the fields in the relationship, namely the ones mentioned in this doc page.
To get to other fields on Lead, you'll have to query the Task first to get its WhoId, then query Lead where the Id equals that WhoId value to get those other fields.
I am attempting to retrieve the owner of a case, based on a partial match, where we choose the most recent case that matches the partial match.
This is the query I am attempting:
SELECT User.CustomField__c
FROM User
WHERE User.Id IN (
SELECT OwnerId
FROM Case
WHERE Case.CaseNumber LIKE '%1026'
ORDER BY Case.CreatedDate DESC LIMIT 1)
The following query works on its own, but doesn't seem happy as part of the subquery:
SELECT OwnerId
FROM Case
WHERE Case.CaseNumber LIKE '%1026'
ORDER BY Case.CreatedDate DESC LIMIT 1
Equally, if I drop the ORDER BY and LIMIT it works:
SELECT User.NVMContactWorld__NVM_Agent_Id__c
FROM User
WHERE User.Id IN (
SELECT OwnerId FROM Case
WHERE Case.CaseNumber LIKE '%1026')
Are order / limit queries not allowed in a SOQL subquery?
Just to clarify this issue, the scenario I am dealing with looks like this...
A Salesforce organisation can configure the "display format" for Case Numbers. If they select "4" digits, you get case numbers like:
0001
0125
1234
33456
It is possible to reconfigure your case numbers to get the following case numbers as well as the case numbers above...
000001
001234
033456
I didn't want people to be confused by the LIKE statement, the issue is that 001234 and 1234 are different cases, so if a customer supplies 1234 and I find two records, I want to start off assuming that they are the most recent case.
So either consider the LIKE statement or an IN statement that contains ('001234', '1234')
There is no documentation I could find that specifies that LIMIT and/or ORDER BY do not work with subqueries, but I ran into the same error you mentioned.
However, it may work to start at the Case object and look up to the User, similar to the Lookup Relationships and Outer Joins section in the SOQL documentation. I'm not sure if this would work for you, but it's something you may want to try.
Here's an example:
-- Edit --
SELECT OwnerId, Owner.CustomField__c
FROM Case WHERE
CaseNumber LIKE '%1026'
ORDER BY CreatedDate DESC
LIMIT 1
Turns out Custom Fields are not accessible because OwnerId is a polymorphic key referencing either Group or User. That means the above won't work, sorry.
To work-around this is very complicated. You would have to create a custom lookup field called "User Owner", or something. That would store a lookup reference to the User, if the Owner is a User (this can be checked by comparing the beginning of OwnerId to '005', the User ID prefix). That field would need to be populated using a after insert, after update Trigger. All values for this new field would need to be dataloaded for previously existing Cases. But, once you have this new "User Owner" field, you can access custom fields on User through SOQL, using it.
ORDER BY and LIMIT don't make sense in your subquery because you're not returning records from the subquery. Instead, the subquery just builds a list of IDs used to filter the main query.
If you use a subquery in a way that the subquery records are returned, these clauses are fine. For example, this works:
SELECT Name,
(SELECT FirstName, LastName FROM Contacts ORDER BY LastName LIMIT 10)
FROM Account
I think it's worth adding that with new features of SOQL that were not available when this question was first asked and answered, that the approach of querying from Case should now be viable (with access to custom fields).
In particular the TYPEOF feature provides access to type specific fields through polymorphic lookups: http://www.salesforce.com/us/developer/docs/soql_sosl/Content/sforce_api_calls_soql_select_typeof.htm
It is worth noting that this feature is still in Developer Preview.
SELECT
TYPEOF Owner
WHEN User THEN CustomField__c
END
FROM CASE
Did you try switching your query around to be something like this?
SELECT OwnerId, (select id from user)
FROM Case
WHERE Case.CaseNumber LIKE '%1026'
ORDER BY Case.CreatedDate DESC LIMIT 1
