TColumn.DefineReferencedCol Method
Copies the data type, length, precision, and scale from a referenced column into this column, and sets ReferencedColumn to RefCol.
Remarks
Used when a foreign-key column must mirror the type information of the primary-key column it references. If RefCol is nil the method does nothing.
Syntax
Unit: Aurelius.Mapping.Metadata
procedure TColumn.DefineReferencedCol(RefCol: TColumn);
