the idea is that i want to know if the 3 triggers will fire or one trigger will overide the other two triggers
say, in the 3 triggers i will update the same column by a diffrent value
what value will the column will take ?

and if the 3 triggers will fires so i want to know the sequence of firing?

thank you
