OGSA-DAI Trigger 1.2 (Default branch)
The OGSA-DAI Trigger component provides a mechanism to notify an OGSA-DAI server when a table in an SQL database has had its rows modified. It then executes a stored OGSA-DAI workflow to perform an action based on the notification. The trigger also provides the old and new values for the modified row which allows specific actions to be taken based on the exact database changes. These actions can use the full range of access, transformation, and delivery functionality available in OGSA-DAI. License: The Apache License 2.0 Changes:
An example Scenario was added to illustrate how the triggers could be used with OGSA-DAI. A crash in the .dll caused by incorrect deallocation of a null pointer was fixed. Many updates and fixes were made to the documentation. Image

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.
