A trigger is a named database object that is associated with a table, and that activates when a particular event occurs for the table. Some uses for triggers are to perform checks of values to be inserted into a table or to perform calculations on values involved in an update. A trigger is associated with a table and is defined to activate when an INSERT,DELETE, or UPDATE statement for the table executes. A trigger can be set to activate either before or after the triggering statement. For example, you can have a trigger activate before each row that is deleted from a table or after each row that is updated. Sender : Yugant khokhar
