Hai,
. I want to create a trigger in Oracle such that when ever I update tableA, the trigger must be activated and insert all the values before updating in to a backup table.
Can any one help me.
Thank You.

Hi,
I have a table named ' Employee' and its backup table ' Upemployee'.
Employee Table
-----------------------
EmpID EmpName

Emp1 ABC
Emp2 XYZ
Emp3 123
When 1st row in table 'Employee' is updated,
ie. If ABC is changed to DEF
a trigger must be activated such that the old values in 'Employee table' gets inserted in to the backup table ' Upemployee'
