Usage

This object helps you replicate the related list functionality of the user interface. To use this object, use the following procedure:

Optionally, issue a describe call against the object whose activities you wish to query, to get a suggestion of the correct SOQL to use.
Issue a SOQL relationship query with a main clause that references the object, and an inner clause that references the activity history, for example:
```
SELECT (SELECT ActivityDate, Description FROM ActivityHistories) 
FROM Account 
WHERE Name Like 'XYZ%'
```
or
```
SELECT (SELECT ActivityDate, Description FROM OpenActivities) 
FROM Account 
WHERE Name Like 'XYZ%'
```

The user interface enforces sharing rules, filtering out related list items that a user does not have permission to see.

In order to prevent performance issues while still providing the related list functionality, there are some restrictions on users who do not have “View All Data” permission. Such users must comply with the following restrictions:

In the main clause of the relationship query, you can reference only one record. For example, you cannot filter on all records where the account name starts with A, but must reference a single account record.
You cannot use WHERE clauses.
You must specify a limit to the number of rows returned, less than 500.
You must sort on ActivityDate and LastModifiedDate, descending order: ORDER BY ActivityDate DESC, LastModifiedDate DESC
