Description

The DELETE TRIGGER command deletes a trigger from the specified table. Triggers are used to evaluate a logical expression when certain operations are attempted.

Keywords	Description
database	The name of the database to which the table belongs. Databases in Recital are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directory is a sub-directory of the Recital data directory. The environment variable / symbol DB_DATADIR points to the current Recital data directory and can be queried using the GETENV() function. Files from other directories can be added to the database using the ADD TABLE command or via the database catalog and SET AUTOCATALOG functionality. The '!' character must be included between the database name and the table name.
table	The name of the table
INSERT | DELETE	Specifies the type of trigger to be deleted.
