Have a go hero - set some default values for other attributes
We have now learned to set the default atribute using Groovy expressions. We will perform
the following exercises to get familiar with the language:
1. Set the default value for
Job
to
CONTRACTOR
when the value of
Empno
is greater
than
100
in
EmpEO
.
2. The
Loc
atribute for the
DeptEO
object will default to
CHICAGO
every ime.
Validation execution
Validaion execuion
is a secion in atribute validaion to set the execuion rule. This is
similar to the execuion rule that we had set for enity-level validaion. The validaion for
the atribute is executed only if the condiion added to the expression editor is saisied.
For example, we can have a compare validaion set on the
Sal
atribute against 1000,
say
9
, and set the validaion execuion condiion as
Job == 'MANAGER'
. This means
the compare validaion is executed only if the
Job
atribute is equal to
MANAGER
.
The validaion execuion secion for enity-level
validaion will include a triggering atribute secion
that is not available in atribute validaion.
