An event trigger fires whenever the event with which it is associated
|
||||
occurs in the database in which it is defined. Currently, the only
|
||||
supported event is <literal>ddl_command_start</>. Support for
|
||||
additional events may be added in future releases.
|
||||
supported events are <literal>ddl_command_start</>
|
||||
and <literal>ddl_command_end</>. Support for additional events may be
|
||||
added in future releases.

The <literal>ddl_command_end</> event occurs just before returning

control from the execution of a <literal>CREATE</>, <literal>ALTER</>,
|

or <literal>DROP</> commmand. It shares the same exceptions as

the <literal>ddl_command_start</> event.
