Description
Indicates the name of the field in its original database table.
Origin is only assigned at design time by the Fields editor, and only when the field component is used by a TQuery object. The Origin property distinguishes the name of the field as it appears in its dataset from the name of the field in the base table on which it is based. For example, in a query that uses the following SQL statement, the value of Origin is CUSTOMER.CUSTNO.
SELECT CUSTNO AS ID FROM CUSTOMER
In this case, the FieldName property is ID.
