Sorry I don't understand.
How would that help to map query against view, say "SELECT RV FROM DYNSQL
WHERE PROC='XXX' AND PARAM='YYY'" to a PL/SQL function call, "XXX('YYY')"?

Well, create a table with procedure names and parameter names and types
for every procedure you need to use like that. That seems to be the most
natural solution to your problem.

We have an application that can easily query a view, but cannot easily--

I am trying to create a custom view to allow this to happen.
For example if application performs the following query:
SELECT RETURN_VALUE FROM TEST_VIEW WHERE PROCEDURE_NAME = 'XXX' AND
PARAM1='YYY' AND PARAM2='ZZZ';
I want to call the function XXXX with the given parameters, ie XXX('YYY',
'ZZZ') and return the values.
I can do the dynamic SQL portion fairly easily (I think), but I am
struggling to understand how I can map the predicates to input and output
parameters to a procedure or function.
Note if handling return value is tricky, might be able to skip that
portion (ie just call procedure XXX('YYY', 'ZZZ').
Any pointers? Thanks in advance.
