* MySQL and CUBRID natively implements this type of clause. jOOQ can
* emulate this clause using a MERGE statement on some other
* databases. The conditions for a RDBMS to emulate this clause are:
*
* - The
INSERT statement's table is a
* {@link Table} with a {@link Table#getPrimaryKey()}
* - The RDBMS supports the
MERGE clause (see
* {@link DSLContext#mergeInto(Table)}).
*
*
* These are the dialects that fulfill the above requirements:
