Aggregate Functions

These functions give you the ability to select a group of records from an arbitrary object and produce an aggregate value, 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.

• Typically, the criteria examines a Lookup field in the specified object and matches that value against the ID of the current record. For example, in a Customer record, the criteria might select for Orders that have a Lookup to the current Customer:

'related_to_Customer =' + record_id

• 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.
