For every visible 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. Making an invisible column visible changes the structure of some records declared with the %ROWTYPE attribute.

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

The %ROWTYPE attribute cannot be used if the referenced character column has a collation other than USING_NLS_COMP.
