/**
* This type is used for the {@link Insert}'s DSL API.
* <p>
* Example: <code><pre>
* DSLContext create = DSL.using(configuration);
*
* TableRecord<?> record =
* create.insertInto(table, field1, field2)
* .values(value1, value2)
* .returning(field1)
* .fetchOne();
* </pre></code>
* <p>
* This implemented differently for every dialect:
* <ul>
* <li>Firebird and Postgres have native support for
* <code>INSERT .. RETURNING</code> clauses</li>
* <li>DB2 allows to execute
* <code>SELECT .. FROM FINAL TABLE (INSERT ...)</code></li>
* <li>HSQLDB, and Oracle JDBC drivers allow for retrieving any table column as
* "generated key" in one statement</li>
* <li>Derby, H2, Ingres, MySQL, SQL Server only allow for retrieving IDENTITY
* column values as "generated key". If other fields are requested, a second
* statement is issued. Client code must assure transactional integrity between
* the two statements.</li>
* <li>Sybase and SQLite allow for retrieving IDENTITY values as
* <code>@@identity</code> or <code>last_inserted_rowid()</code> values. Those
* values are fetched in a separate <code>SELECT</code> statement. If other
* fields are requested, a second statement is issued. Client code must assure
* transactional integrity between the two statements.</li>
* </ul>
