Answer 1

what the problem in constructing??
you can use something like this....
declare
vStrng varchar2(100) := 'JOHN NAME SMITH';
v_temp varchar2(1000):= 'SELECT  DISTINCT  firstname,lastname FROM employees,
  (SELECT regexp_substr('''||vStrng||''',''[[:alpha:]]+'',1,level) parsedstr
     FROM dual
    CONNECT BY level<=LENGTH(regexp_replace('''||vStrng||''',''[[:alpha:]]'',''''))+1
  ) WHERE instr(firstname,parsedstr)>0 OR instr(lastname,parsedstr)      >0';
vSQL varchar2(1000):= 'SELECT ENAME,EMPNO,DEPT.DEPTNO FROM EMP,DEPT WHERE EMP.DEPTNO=DEPT.DEPTNO AND (firstname,lastname) in ('||v_temp||')';
begin
--rest of your code....
end;edit: In the same way...you can use any of the above mentioned solutions..
