Validation in entity level

Question

hi all
I have an entity "currncy" and I want to make
a validation in entity level on its attribute "Isdefaultcurrency"
which is boolean.
Entity Object : Currency
attributes :
1. Currencyid DBsequence
2. Currencyname String
3. Isdefaultcurrency, Boolean, CheckBox
Rule Type : List
Operator : In
List Type : Query Result 'select ISDEFAULTCURRENCY from currency where ISDEFAULTCURRENCY=1'
I want when user insert in table, validation checks the attribute 'Isdefaultcurrency'
was true then show the error message that there was default currency and if you
want to set it to true (or default) you must change another record that was true
and uncheck it then back to current record and will make it true and
there is one record in my table that its attribute 'Isdefaultcurrency' must be true
please explain it
