Field Names – Referencing a Field in a Table

The field names used in a query or predicate expression have the following form:

[table-name.]field-name[:attribute-name]

An optional table name followed by a period, a field name and an optional variable attribute name preceded by a colon.

Never enter the period without a table name, or a colon without an attribute name.

•

Table-name: is used only in join searches. It is required only if the field-name is not unique in the set of tables included in the join.

•

Field-name: is always required. It identifies the field in the table.

•

Attribute-name: is allowed only if the field is a variable attributes field. It specifies which attribute value in the field is desired. If field-name specifies a variable attributes field, and an attribute-name is not specified the reference is to the concatenation of all attribute values in the field.
