try

CREATE SQL VIEW HonVed AS SELECT Hon.*, Homo.Ime;
                FROM  honorar!hon  LEFT OUTER JOIN honorar!homo    ON  Hon.egn = Homo.egn;
                WHERE Hon.dataved = ?getdataved;                  && Date field
                AND (!m.hon_ved1 OR Hon.lev1==?get_lev1);  && Integer field
                AND (!m.hon_ved2 OR Hon.lev2==?get_lev2);  && Integer field
                AND (!m.hon_ved3 OR Hon.lev3==?get_lev3)   && Integer field
<PRE>

Next can do the job only if hon_vedN+1 =.T. => hon_vedN =.T.
<pre>
...
                WHERE DTOS(Hon.dataved)+STR(Hon.Lev1)+STR(Hon.Lev2)+STR(Hon.Lev3);
                       = ?getdataved+;
                   +IIF(m.hon_ved1,?STR(get_lev1),'') );
                   +IIF((m.hon_ved2,?STR(STget_lev2),''));
                   +IIF(!m.hon_ved3,?STR(get_lev3),''))
* OR
                WHERE DTOS(Hon.dataved)+STR(Hon.Lev1)+STR(Hon.Lev2)+STR(Hon.Lev3);
                       LIKE ?getdataved+;
                   +IIF(m.hon_ved1,?STR(get_lev1),'%') );
                   +IIF((m.hon_ved2,?STR(STget_lev2),'%'));
                   +IIF(!m.hon_ved3,?STR(get_lev3),'%'))

next can do the job without restrictions, but optimization ????

                WHERE DTOS(Hon.dataved)+STR(Hon.Lev1)+STR(Hon.Lev2)+STR(Hon.Lev3);
                       LIKE ?getdataved+;
                   +IIF(m.hon_ved1,?STR(get_lev1),'??????????') );
                   +IIF((m.hon_ved2,?STR(STget_lev2),'??????????'));
                   +IIF(!m.hon_ved3,?STR(get_lev3),'??????????'))

why not BINTOC() ?
