Interface DataField

Always signifies that the field value will be computed on any write (INSERT OR UPDATE) operations. The field cannot be written to, and when read the result of the last generated expression will be returned.

The generation expression can refer to other columns in the table, but not other generated columns. Any functions and operators used must be immutable. References to other tables are not allowed.

The default expression will be used in INSERT operation that does not specify a value for the field.

If there is no default for a field, then the default is null.
