How to: Configure the nested triggers Option (SQL Server Management Studio)
Use the nested triggers option to control whether an AFTER trigger can cascade; that is, perform an action that initiates another trigger, which initiates another trigger, and so on. When nested triggers is set to 0, AFTER triggers cannot cascade. When nested triggers is set to 1 (the default), AFTER triggers can cascade to as many as 32 levels. INSTEAD OF triggers can be nested regardless of the setting of this option.
To set the nested triggers option
In Object Explorer, right-click a server, and then select Properties.
On the Advanced page, set the Allow Triggers to Fire Others option to True (the default) or False.
