Re: dynamic sql or not? that is the question

John,

Maybe you could you do a (C) loop in Pro*C and repeat the following for each keyword in the list (pass each one in (e.g. from a C array) as "bind_var_keyword"):-

select id, count(id)
into :bind_var_id, :bind_var_count
from keywords
where keyword like :bind_var_keyword||'%';

The results of each select (or better still cursor open/fetch/close) could then be stored back in 2 C arrays : Not beyond the wit of man to then sort the results if that's what you need.
But then again, you could use dynamic SQL if you want to do it all in one database 'hit' and let Oracle do the sorting for you. Depends if you're more comfortable with C or Dynamic SQL (I'm guessing the former).
Having said that, dynamic SQL isn't that hard : it's mostly about composing a string which contains the SQL statement (plus some stuff to do with bind variables). I did it a while ago in Pro*Fortran which I presume is similar (in principle) to Pro*C.

Carl.
