Now that (from UV10.1) Index-based triggers are officially supported, can these 
replace your SQL-based triggers? These have less functionality and less 
overhead, but that's the price you have to pay....

Can't say I had a chance to try it for myself...yet...!

Subject: [U2] [UV] Do you avoid TRIGGERS because of the difficulty using DEBUG 
or RAID with them? Was: Universe Triggers

How many people avoid using triggers BECAUSE of the virtual impossibility of 
using RAID with Triggers?
