  • UPDATE - update rows of a table

    UPDATE [ ONLY ] table [ [ AS ] alias ]
               SET { column = { expression | DEFAULT } |
                     ( column [, ...] ) = ( { expression | DEFAULT } [, ...] ) } [, ...]
               [ FROM fromlist ]
               [ WHERE condition | WHERE CURRENT OF cursor_name ]
    UPDATE  changes  the  values  of the specified columns in all rows that
           satisfy the  condition.  Only  the  columns  to  be  modified  need  be
           mentioned  in  the  SET  clause; columns not explicitly modified retain
           their previous values.
