Creates a DML, DDL, or logon trigger. A trigger is a special type of stored procedure that automatically runs when an event occurs in the database server. DML triggers run when a user tries to modify data through a data manipulation language (DML) event.

To create a trigger in any schema on a table in any schema, or on another user's schema ( schema. SCHEMA ), you must have the CREATE ANY TRIGGER system privilege.Trigger’s context variable holds the values of the record which initiated the execution of the trigger, for e.g. Trigger.New contains the list of contacts which initiated the trigger. There are some Trigger’s context variables which return Boolean values and with the help of context variables, we can determine which event fired the trigger.
Trigger names exist in the schema namespace, meaning that all triggers must have unique names within a schema. Triggers in different schemas can have the same name. This section describes CREATE TRIGGER syntax. For additional discussion, see Section 23.3.1, “Trigger Syntax and Examples”.
