NAME

       ALTER TRIGGER - change the definition of a trigger

SYNOPSIS

       ALTER TRIGGER trigger ON table
	   RENAME TO newname

   INPUTS
       trigger
	      The name of an existing trigger to alter.

       table  The name of the table on which this trigger acts.

       newname
	      New name for the existing trigger.

   OUTPUTS
       ALTER TRIGGER
	      Message returned from trigger renaming.

       ERROR  Message returned if trigger is not available, or new name is a duplicate of another existing trigger on the table.

DESCRIPTION

       ALTER  TRIGGER  changes the definition of an existing trigger.  The RENAME clause causes the name of a trigger on the given table to change
       without otherwise changing the trigger definition.

       You must own the table on which the trigger acts in order to change its properties.

   NOTES
       Refer to CREATE TRIGGER for a further description of valid arguments.

USAGE

       To rename an existing trigger:

       ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;

COMPATIBILITY

   SQL92
       The clause to rename triggers is a PostgreSQL extension from SQL92.

NAME

       DROP TRIGGER - remove a trigger

SYNOPSIS

       DROP TRIGGER name ON table [ CASCADE | RESTRICT ]

   INPUTS
       name   The name of an existing trigger.

       table  The name (optionally schema-qualified) of a table.

       CASCADE
	      Automatically drop objects that depend on the trigger.

       RESTRICT
	      Refuse to drop the trigger if there are any dependent objects.  This is the default.

   OUTPUTS
       DROP TRIGGER
	      The message returned if the trigger is successfully dropped.

       ERROR: DropTrigger: there is no trigger name on relation "table"
	      This message occurs if the trigger specified does not exist.

DESCRIPTION

       DROP  TRIGGER will remove an existing trigger definition. To execute this command the current user must be the owner of the table for which
       the trigger is defined.

EXAMPLES

       Destroy the if_dist_exists trigger on table films:

       DROP TRIGGER if_dist_exists ON films;

COMPATIBILITY

       SQL92  There is no DROP TRIGGER statement in SQL92.

       SQL99  The DROP TRIGGER statement in PostgreSQL is incompatible with SQL99. In SQL99, trigger names are not local to tables, so the command
	      is simply DROP TRIGGER name.
