These functions give you the ability to select a group of records from an arbitrary object and produce an aggregate value (SUM, COUNT, MAX, MIN, AVG), without having to write Java code.
Methods Field Types SUM(object_id, object_field, criteria) number, currency, boolean AVG(object_id, object_field, criteria) number, currency, boolean MAXIMUM(object_id, object_field, criteria) number, currency, date MINIMUM(object_id, object_field, criteria) number, currency, date COUNT(object_id, criteria) n/a
where:
- object_id - Object Name or Object Identifier
- object_field - Field in the specified object
- Restriction: A Lookup field cannot be used.
- criteria: - A condition that specifies the object records that are part of the collection.
- Syntax is same as searchRecords() API of JAVA/REST criteria
- Syntax is same as searchRecords() API of JAVA/REST criteria
The relevant information is here (only the page title is inappropriate): JAVA_API:Filter_Expressions_in_JAVA_APIs
- Criteria must contain at least one index field. If index is combination of fields, the criteria must contain first field in that index. (It does not need to be a unique index, but an index is required, for performance.)
- Note: The maximum number indexes currently allowed in an index definition is 5.
- Considerations
-
- The SUM() of a boolean field gives a count of values that are yes/true.
- The AVG() of a boolean field gives the percentage that are yes/true.
Note: The results doenot take into account user-security restrictions. These functions operate on the entire set of records in an Object, regardless of user capabilities.
- Availability
The Aggregate Functions are available here:
- Validations
- Data Policies
- Criteria (Action Based - Add, Updae, Delete, Import Record, Ownership Change, Workflow State Change)
- Add/Update Record Action
- Calendar Data Policies - Criteria Not Support
- Calendar Data Policies - Add/Update Record Actions Aggregate functions will be evaluated.
- Default Values
- Formula Fields
They are not available here:
- Layout Rules
- Custom Access Criteria
- Reports
