<trigger definition> ::=
  CREATE TRIGGER <trigger name> <trigger action time> <trigger event>
      ON <table name> [ REFERENCING <transition table or variable list> ]
      <triggered action>

<triggered action> ::=
  [ FOR EACH { ROW | STATEMENT } ]
      [ WHEN <left paren> <search condition> <right paren> ]
      <triggered SQL statement>

<triggered SQL statement> ::=
    <SQL procedure statement>
  | BEGIN ATOMIC { <SQL procedure statement> <semicolon> }... END
