Description
Field can be any of the following:
• a repeating field (repeatingField).
• a field in matching related records specified by (table::field), whether or not these
records appear in a portal.
• several non-repeating fields in a record(field1;field2;field3...).
• corresponding repetitions of repeating fields in a record
(repeatingField1;repeatingField2;repeatingField3), if the result is returned
in a repeating field with at least the same number of repeats.
• several fields in the first matching record specified by
(table::field1;table::field2;...). You can include fields from different tables
(table 1::field A;table 2::field B...).
Examples
A Student table has a portal showing scores for all exams a student has taken. The exam scores are
in a table called Exams.
Average(Exams::Score) returns the student’s average score for all exams she has taken.
In the following examples:
• Field1 contains two repetitions with values of 1 and 2.
• Field2 contains four repetitions with values of 5, 6, 7, and 8.
• Field3 contains 6.
Average(Field2) returns 6.5 when the calculation isn’t a repeating field.
Average(Field1;Field2;Field3) returns 4, 4, 7, 8 when the calculation is a repeating field.
