SOQL Subquery counting the number of results - salesforce

I'm trying to create a SOQL query that pulls records from an Object based on if there are any results from another linked object. Here is sort of what I am trying to do.
SELECT id, casenumber FROM case WHERE count(SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId = case.id) > 0
This returns the error,
MALFORMED_QUERY:
casenumber FROM case WHERE count(SELECT ContentDocumentId FROM ContentDocumentLink
^
ERROR at Row:1:Column:44
unexpected token: 'SELECT'
After a few attempts at trying to make this work I am not sure what else try. I know SOQL has some limitations but I am unsure if this is one of them. Anyone have insight? Thanks.

It's "down, then up", via many to many relationship. 1 document could be linked to many Cases but wasting storage space just once.
Normally you'd try something like this
SELECT Id, CaseNumber, Subject
FROM Case
WHERE Id IN (SELECT LinkedEntityId FROM ContentDocumentLink)
But it won't compile, there are some limitations. Experiment, worst case query all cases and use apex to inspect the related list?
SELECT Id, CaseNumber, Subject, (SELECT ContentDocumentId FROM ContentDocumentLinks LIMIT 1)
FROM Case
Case is funny. Attachments linked to emails (if you have Email-to-Case) will show on related list of Files but they won't be physically there. The full link will be Content Document -> ContentDocumentLink -> EmailMessage -> Case. Argh. CombinedAttachment is supposed to help with it, special readonly related list / view / whatever.
One more idea using polymorphic soql, bit bass-ackwards but give it a go:
SELECT ContentDocumentId, TYPEOF LinkedEntity WHEN Case THEN Id, Subject, CaseNumber END
FROM ContentDocumentLink
WHERE LinkedEntityId IN (SELECT Id FROM Case)

Look for records related to another related records within specific criteria

I am trying to created a set of records based on some criteria and i need to figure out the best way to do this.
I want to create a record for every object A and B that has an specific Account object. object A needs to have a status of "DONE", and B a status of "READY" in order to create the record (which will be an Object A with an "Active" status) the fields on the new Object A will copy from some of the Object A and B fields.
This is a process im not triggering from user action but a set of records i need to already dump in the database. I do have a sandbox to start working on and testing then rolling out.
Please let me know the easiest way to do this.
I appreciate the help!
You didn't provide enough info, we don't know how the relations look like. Are A and B related lists under Account? Are they independent or is there some link from one to another?
I'll write what I would do as a script (if needed you could make a batch job out of it or perhaps you'll be more comfortable with Data Loader, reports with cross filters, MS Excel and orgy of VLOOKUPs...)
To identify all "candidate" accounts you can try with this skeleton of a query
SELECT Id, Name
FROM Account
WHERE Id IN (SELECT Account__c FROM A__c WHERE Status__c = 'Done')
AND Id IN (SELECT Account__c FROM B__c WHERE Status__c = 'Ready')
LIMIT 10000
Now, the question about amounts of data. Will it return 10K (which is limit of records you can insert/update/modify in single transaction), if more - you might have to chunk it somehow... Maybe ORDER BY Id, record Id of last processed Account and in next iteration add AND Id > '001....'
Anyway, we got a "candidate", well, maybe he already has an Active A record, we wouldn't want to make a duplicate. And besides we need to pull some fields from B so they'd be copied across. So let's modify the query a bit, to add "subqueries" (think of them as related lists or LEFT INNER JOINs if that helps)
SELECT Id, Name,
(SELECT Id FROM As__r WHERE Status__c = 'Active' LIMIT 1),
(SELECT SomeField__c, SomeOtherField__c FROM Bs__r WHERE Status__c = 'Ready' LIMIT 1)
FROM Account
WHERE Id IN (SELECT Account__c FROM A__c WHERE Status__c = 'Done')
AND Id IN (SELECT Account__c FROM B__c WHERE Status__c = 'Ready')
LIMIT 10000
Nice. So now you need to loop through accounts, see if they contain that at least 1 active record (and if they do - skip). If they don't - create new one.
List<A__c> toInsert = new List<A__c>();
for(Account a : [SELECT...]){
if(a.As__r.isEmpty() && !a.Bs__r.isEmpty()){
toInsert.add(new A__c(
Account__c = a.Id,
Status__c = 'Active',
Foo__c = a.Bs__r[0].SomeField__c,
Bar__c = a.Bs__r[0].SomeOtherField__c + 7
));
}
}
insert toInsert;

Filtering issue with multiple forloop in apex | salesforce

I have a scenario where multiple loopings are causing the system resource error.
I need some help with map of map syntax or coding sample for this requirement.
Requirement is:
Account has 1 or more ReportCard records.
ReportCard has Account and Contact.
Now i need to get the list of ReportCards and filter by 1 per contact and recently created records only.
If ReportCard has 2 records with same contact, include only recently created.
// get list of unique accounts from the set
list<Account> accList = new list<Account >([SELECT Id,Average_of_Pulse_Check_Recommend_Score_N__c,Average_of_Recommend_Score_Lanyon_N__c,Average_of_Touchpoint_Recommend_Score_N__c,Average_of_Touch_Point_Satisfaction_N__c FROM Account WHERE Id in:AccIds]);
list<ReportCard__c> allRCList = new list<ReportCard__c>([SELECT Id,Net_Promoter_text__c,CreatedDate, Contact__c, Account__c, RecordTypeID, Touchpoint_Satisfaction_text__c FROM ReportCard__c WHERE Account__c in:accList Order By Account__c, CreatedDate Desc]);
List<ReportCard__c> rcListbyAccounts = new List<ReportCard__c>();
for(Account acc:accList)
{
Any help would be appreciated.
Thanks
I'm not sure I understand your situation correctly. You've skipped the for loop - I strongly suspect any issues you have there sit in the loop rather than in the queries.
Looks like you should read about using relationship queries (salesforce versions of JOIN in regular database): http://www.salesforce.com/us/developer/docs/soql_sosl/Content/sforce_api_calls_soql_relationships.htm
Pay special attention to subqueries (which behave similar to how a related list behaves on record's detail page).
From what I see I'd say you don't need to query for Accounts at all, or at least not like that. This will work equally well:
SELECT Id,Net_Promoter_text__c,CreatedDate, Contact__c, Account__c, ...
FROM ReportCard__c
WHERE Account__c in:accIds
ORDER BY Account__c, CreatedDate Desc
Now lets attack this:
List of ReportCards and filter by 1 per contact and recently created
records only. If ReportCard has 2 records with same contact, include
only recently created.
I'd reverse it - I'd start the query from Contact level, go down to the related list of Report Cards and pick the latest one. That way it eliminates the issue with duplicate contacts for you. Something like this:
SELECT Id, Name, Email,
(SELECT Id, Net_Promoter_text__c, CreatedDate, Account__c, Account__r.Name, Account__r.Average_of_Pulse_Check_Recommend_Score_N__c
FROM ReportCards__r
WHERE Account__c IN :accIds
ORDER BY CreatedDate DESC
LIMIT 1)
FROM Contact
WHERE AccountId IN :accIds
This goes from Contact "down" to Report Cards (via the relationship name ReportCards__r) and then "up" from Card to Account via Account__r.Name, Account__r.Average_of_Pulse_Check_Recommend_Score_N__c...

Salesforce - Apex - query accounts based on Activity History

Hey Salesforce experts,
I have a question on query account information efficiently. I would like to query accounts based on the updates in an activityHistory object. The problem I'm getting is that all the accounts are being retrieved no matter if there's "complete" activeHistory or not. So, Is there a way I can write this query to retrieve only accounts with activeHistory that has status="complete" and Type_for_reporting='QRC'?
List<Account> AccountsWithActivityHistories = [
SELECT
Id
,Name
,( SELECT
ActivityDate
,ActivityType
,Type_for_Reporting__c
,Description
,CreatedBy.Name
,Status
,WhatId
FROM ActivityHistories
WHERE Status ='complete' and Type_for_Reporting__c = 'QRC'
)
FROM Account
];
You have a WHERE clause on the histories but you still miss one on the Account level.
For example this would return only Accounts that have Contacts:
SELECT Id, Name
FROM Account
WHERE Id IN (SELECT AccountId FROM Contact) // try with NOT IN too
With Activities it's trickier because they don't like to be used in WHERE in that way.
http://www.salesforce.com/us/developer/docs/officetoolkit/Content/sforce_api_calls_soql_select.htm
The following objects are not currently supported in subqueries:
ActivityHistory
Attachments
Event
EventAttendee
Note
OpenActivity
Tags (AccountTag, ContactTag, and all other tag objects)
Task
Additionally the fine print at the bottom of ActivityHistory definition is also a bit discouraging.
The following restrictions on users who don’t have “View All Data” permission help prevent performance issues:
In the main clause of the relationship query, you can reference only
one record. For example, you can’t filter on all records where the
account name starts with ‘A’; instead, you must reference a single
account record.
You can’t use WHERE clauses.
You must specify a limit of 499 or fewer on the number of rows returned in the list.
You must sort on ActivityDate in ascending order and LastModifiedDate in descending order; you can display nulls last. For
example: ORDER BY ActivityDate ASC NULLS LAST, LastModifiedDate DESC.
Looks like you will need multiple queries. Go for Task (or Event, depending for which the custom field is visible), compose a set of AccountIds and then query the Accounts?
Or you can manually filter through list from your original query, copying accounts to helper list:
List<Account> finalResults = new List<Account>();
for(Account a : [SELECT...]){
if(!a.ActivityHistories.isEmpty()){
finalResults.add(a);
}
}

soql select individual CaseComment with all its FeedComments

I am trying to select all comments ,feeds and feedcomments for an individual case.
The hierarchy is like
Case
|
CaseComment
|
FeedComments(commnets or feeds under a CaseComment)
I could not find any relation between CaseComments and FeedComments nor CaseComments and CaseFeeds.
How can I select all together in a soql or individual soqls which relates Case, CaseComment,CaseFeed,FeedComment?
EDIT
The query you've included in the comment looks good. I'd write it as something like that:
SELECT Id, Body, ParentId, Parent.CaseNumber, CreatedDate,
(SELECT Id, CommentBody, CommentType FROM FeedComments)
FROM CaseFeed
ORDER BY Parent.CaseNumber, CreatedDate
(this is sample output rendered in Real Force Explorer, a pretty neat tool)
If I'll click into the "2 records" bit I can drill down to the fields selected from FeedComment for "this" CaseFeed:
If your query renders differently for you (some stuff is blank) - maybe try this different editor or even go to https://workbench.developerforce.com
If only some comments contain text - they might be uploaded images for example - filter them by CommentType = 'TextComment'?
ORIGINAL
FeedComments(commnets or feeds under a CaseComment)
No, not really. FeedComment is a Chatter table that can link to many objects but CaseComment is not one of them.
Maybe study the Chatter Entity Relationship Diagram?
Anyway - relationship to feed* objects doesn't have a nice name exposed so we can't query it all in one go:
I think you'll need something like this:
SELECT Id, CaseNumber,
(SELECT Id, CommentBody FROM CaseComments),
(SELECT Id, Body FROM Feeds)
FROM Case
SELECT Id, FeedItemId, ParentId, CommentBody
FROM FeedComment
WHERE ParentId = :caseIdHere

Chatter : SOQL for fetching CommentLikes

I have requirement to fetch comment likes. I'm not able to figure out on how to retrieve commentlikes.
FeedLike object represents likes. You can't query FeedLike records directly. They can only be queried via the parent NewsFeed, UserProfileFeed, or entity feed, such as AccountFeed.
So to query FeedPost likes, use following:
SELECT Id, (SELECT Id, CreatedById, CreatedDate, FeedItemId, FeedEntityId FROM FeedLikes) FROM UserFeed
to query group post likes, use following:
SELECT Id, (SELECT Id, CreatedById, CreatedDate, FeedItemId, FeedEntityId FROM FeedLikes) FROM CollaborationGroupFeed
How to retrieve comment likes?
They are available through the Chatter REST API: http://wiki.developerforce.com/page/Chatter_API
I think you want to ChatterActivity SObject
Select c.ParentId, c.LikeReceivedCount, c.Id, c.CommentReceivedCount From ChatterActivity c
This should get what you are looking for.
EDIT:
Strange, I don't seem to be able to find anything on doing this in apex, you can do it through the api by calling
/chatter/comments/commentId/likes
So it should be possible somewhere along the line.This could work as a workaround though.
