alter_trigger
ALTER
TRIGGER(7) SQL Commands ALTER TRIGGER(7)
NAME
ALTER TRIGGER - change the definition of a trigger
SYNOPSIS
ALTER TRIGGER name ON table RENAME TO newname
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 The name of the table on which this trigger acts.
newname
The new name for the trigger.
NOTES
The ability to temporarily enable or disable a trigger is provided by ALTER TABLE [alter_table(7)], 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.
