Report with dynamic order by (binding of parameter)

Question

hy,
my problem is the following:
i want to let the user customize the ordering of a portal report.
but the binding does not really work, the bind variable seems to
have no effect in the order by clause.
code sample:
select * from SCOTT.EMP order by :p_order
then, portal gets the right value for the parameter:
:p_order binding with HIREDATE
but: this results in an emp table sorted by the empno.....
and not by the hiredate
do you have any ideas how to get this working ???
thanx, martin allhoff

Hi, the way to do this is to pass in a different set of
parameters. Try not using the :bind parameter in the report
query, but instead, call your report like this:
http:// ... /pls/portal30/Schema.report.show?
p_arg_names=_ORD_BY_COL&P_arg_values=HIREDATE
then try calling
http:// ... /pls/portal30/Schema.report.show?
p_arg_names=_ORD_BY_COL&P_arg_values=EMPNO
to see if indeed it is dynamically selecting the order by clause
based on the info passed in. Also, check my syntax, I cant
remember if ORDBY_COL is correct or not. But any possible
options should be listed for you in the "Display Call Interface"
screen for the report.
