Laurits Sogaard Nielsen: "Oracle Maestro (and also MS SQL Maestro) are the perfect substitutes for TOAD and in some ways also much better products (they are much cheaper, and the support is fast and easy). I'm looking forward to getting much more experience with both products, that already now have proven themselves to be fantastic".
Bernhard Hartl: "Oracle Maestro works great - thank you for that really good product and the very good User Interface".

Database Trigger Editor

Database Trigger Editor can be opened automatically after the trigger is created and is available on editing (see Editing Triggers for details).

 

The basic principles of Object Editors in Oracle Maestro are considered in the corresponding topic. See below to find the description of editor tabs that are unique to the current object.

 

Database Trigger Editor provides you with an ability to edit trigger properties. The Properties tab allows you to change the trigger name, the trigger definition, and the trigger events.

 

The Errors tab displays all the necessary information about object errors. If an error have occurred during the object compilation it appears in the list with some additional properties: Order (one after another), Line and Position (object definition location the error was found out), Error (corresponding PL/SQL exception).

Name

Use the field to rename the database trigger.

 

Is enabled

Check the option to enable the trigger.

 

When fire (Before, After)

Specify Before to cause the database to fire the trigger before executing the triggering event. For row triggers, the trigger is fired before each affected row is changed. Specify After to cause the database to fire the trigger after executing the triggering event. For row triggers, the trigger is fired after each affected row is changed.

 

When condition

Specify the trigger condition, which is a SQL condition that must be satisfied for the database to fire the trigger.

 

Server error

Check the box to fire the trigger whenever a server error message is logged.

 

Logon

Specify the option to fire the trigger whenever a client application logs onto the database.

 

Logoff

Use the option to fire the trigger whenever a client application logs off the database.

 

Startup

Specify the clause to fire the trigger whenever the database is opened.

 

Shutdown

Specify the option to fire the trigger whenever an instance of the database is shut down.

 

Suspend

Use the clause to fire the trigger whenever a server error causes a transaction to be suspended.

 

To apply the changes, select the Apply Changes item in the Navigation bar or use Ctrl+F9 or Ctrl+F7 shortcut keys.

 

It is also possible to modify object properties without opening the object editor: use the Object Properties item of the popup menu of the selected object from the explorer tree.
