In order to perform the following exercises you will need to
create a table withcolumns as shown below:
EMPLOYEE:Empid num erEmpname varchar !"#$
Empgrade number Empsalary number
Your tas% is to create a procedure which& when evo%ed&
will increase the salary for anemployee by '"## or '(### depending
on his or her grade !the higher the grade& thehigher the
employee)s ran%ing within the company$* You will need to populate
the tablefirst with a minimum of (# entries& the empgrade value
of which should be between ( and"* + script file Create!Emp"s#$ is
provided on ,lac%board for this purpose*
-he code overleaf will provide a s%eleton for the procedure&
but you will need to fillin the missing bits indicated by o$d
letters* You are recommended to use .otepad to do
the editing& and you will need to give your file the
extension "s#$&e.g * calling itsa$ar%!in&rease"s#$ * Once
you have done this& you should attempt to compile the code by
means of the ' command !using the full path/name of the file$ in
01L2Plus* IfOracle tells you that the procedure has been compiled
with errors& entering the commands(o) errors will list the
problems with the code* Once the procedure has
compiledsuccessfully& you can run it by typing e*e&ute
sa$ar%!in&rease at the 01L3 prompt*
.O-E0:4emember that you need to have a variable to store each
component of the return fromthe cursor*5here an I6 statement is
used& remember to E.7 I68
