From the info you provided, its nearly impossible to tell. some things to consider -

1. If its a plsql procedure, it doesn't return a value, so your idea of calling itsomehow inside a select won't work.
2. In pl/sql, functions return values, not procedures. If it is a function, then you might be able to do something. However, you need to read up on the restrictions on using user defined functions in sql - see the sql reference manual.
3. The only way I can think of to get a value out of a procedure is if one of its arguements is defined as an OUT or IN OUT parameter.
