@Support(value={ASE,CUBRID,DB2,DERBY,FIREBIRD,H2,HANA,HSQLDB,INFORMIX,INGRES,MARIADB,MYSQL,ORACLE,POSTGRES,SQLSERVER,SYBASE}) SelectForUpdateOfStep<R> forUpdate()
FOR UPDATE
clause to the end of the query.
Note: not all SQL dialects allow for combining a FOR UPDATE
clause with LIMIT .. OFFSET
, or with GROUP BY
.
This essentially includes SQLDialect.INGRES
and
SQLDialect.ORACLE
. These incompatibilities are not reflected by
the jOOQ API.
