%ROWTYPE Attribute

The %ROWTYPE attribute lets you declare a record that represents either a full or partial row of a database table or view. For every column of the full or partial row, the record has a field with the same name and data type. If the structure of the row changes, then the structure of the record changes accordingly.

The record fields do not inherit the constraints or initial values of the corresponding columns.
