Default Re: in PL/SQL : String replace on some condiations - i hate IF ELSE

Is this a comlete string evaluation, or dealing with token replacement
in a string? The pseudo code you posted points to the former... If that
is the case, I would not even bother doing it in PL/SQL. I would use
SQL, a lookup table (containing the matching string and replacement
string), and a join.

If this is token replacement, I would also first consider using SQL -
with a LIKE condition as oppose to a normal join.

The reason why I want to try SQL first is that it simply deals a lot
better with data volumes than PL/SQL. It performs much faster, scales
vastly better, than doing similar in PL/SQL.
