ALTER TRIGGER
ALTER TRIGGER — change the definition of a trigger
Synopsis
ALTER TRIGGERname
ONtable_name
RENAME TOnew_name
Description
ALTER TRIGGER
changes properties of an existing trigger. The RENAME
clause changes the name of the given trigger without otherwise changing the trigger definition.
You must own the table on which the trigger acts to be allowed to change its properties.
Parameters
name
The name of an existing trigger to alter.
table_name
The name of the table on which this trigger acts.
new_name
The new name for the trigger.
Notes
The ability to temporarily enable or disable a trigger is provided by ALTER TABLE, not by ALTER TRIGGER
, because ALTER TRIGGER
has no convenient way to express the option of enabling or disabling all of a table's triggers at once.
Examples
To rename an existing trigger:
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;
Compatibility
ALTER TRIGGER
is a PostgreSQL extension of the SQL standard.
