I also recommend avoiding use of dynamic SQL unless you cannot solve your business problem any other way.
If you really need dynamic SQL then look in the PL/SQL manual at the execute immediate statement and for more complex SQL look in the PL? SQL Packages and Type Reference manual at the entry for package dbms_sql.
Packages and overloading procedure/function calls as Sybrand mentioned is a potential alternate approach. You might also be able to make use of weakly typed reference cursors.
