INTEGER expressions return integers (whole
numbers).
INTEGER expressions can be used to combine expressions, do
arithmetic, and test conditions for conditional evaluation. The
INTEGER PERL expression uses Perl to manipulate the data.
The Perl code is contained in an
EXPRBODY element. The Zinc Perl module provides
classes and methods for gaining access to and manipulating the current record.
Objects accessed from Perl are copies of the current data; changing the Perl
objects has no effect on the current data until a function is called to
explicitly copy the Perl objects back.
Oracle recommends that you perform record manipulation with the
PERL_MANIPULATOR element rather than with the
EXPRESSION and
RECORD_MANIPULATOR elements. However, if you need to
access and modify dimension sources (such as a dimension adapter or dimension
server) you should still use expressions such as
DVAL PERL. The Perl manipulator does not access
dimension sources.
See the
EXPRESSION element for DTD and attribute information.
