To create a new trigger, right click on a node of a table for which you wish to add a trigger. From the node's context menu, choose the Create Trigger command. This command opens the SQL Editor.
To modify an existing trigger, double click on a node of the trigger you wish to modify, or right click on this node and choose the Alter Trigger command from a context menu. Either of the commands opens the SQL Editor.
To create or alter the trigger definition using SQL Editor, type the trigger statement in the SQL Editor using standard SQL.
You should enter only the trigger statement, that is the part
of the CREATE TRIGGER
query that is placed
after the FOR EACH ROW
clause.
All other trigger properties are set in the Properties window. These properties are:
Definer
Event Manipulation
Name
Timing
Some of these properties can have arbitrary text values, others accept values only from a predefined set.
The properties Event Table, Schema and Server in the Properties window are read-only.
To save changes you have made, use either Save or Save All buttons of the Visual Studio main toolbar, or just press Ctrl+S. A confirmation dialog will confirm whether you want the changes saved to the database.
