As a rule, the query field has the same type as the corresponding base table field. However, there are some differences. For example, the query field with a set reference table will have the type of reference field value. The type of the calculated field is determined by the operation and the type of the primary field. For operations of counting total numbers (“Number of records”, Number of not empty values”, “Number of empty values” “Number of values “True” and “Number of values “False”) the type of the calculated field will be integer. For the operations “Minimum”, “Maximum” and “Sum” the type of the calculated field corresponds to the type of the primary field. For the operation “Average” it will be real type.
Field attributes of a query correspond to the attributes of base tables fields.
