Hi,

I would like to know how I can use trigger to update (1 or more fields)
a table.

For example if customer table has the following fields:
-name
-address
-sex

I want to create a trigger to update another table (say backup) whenever
one or more fields in customer table are updated. How do i call the field
that has been changed so that i can use that field to update the backup
table
