* A data type corresponding to JDBC's {@link Types#ROWID}.
*
* In certain RDBMS, referencing a row by its ROWID may be quicker
* than looking it up by a primary key. This can be particularly useful when
* self joining a table in a {@link Merge} statement and comparing the two
* versions of the table by ROWID.
*
* Instances can be created using {@link Table#rowid()}.
