Capability not support (delphi c/ss,BDE5.01,Personel ORacle 8.04

hi,
    I'm trying to migrate my application from Delphi3 to Delphi4, from
Oracle7.3 to 8.04.
    they works fine except some query with live result.
   these queries work in delphi3 c/s.
    When I try to change  values in Query,I get message ('Capability Not
Support')

     query1:SELECT NO1,NO2 FROM OWNER.TABLE1
                  WHERE NO1=:NO1
                  ORDER BY NO2

    BDE Parameters;
    DLL32: SQLORA8.DLL
    VENDOR INIT: OCI.DLL
    NET Protocol: TNS

if I use SQLORA32.DLL instead of SQLORA8.DLL,I do not get msg('Capability
not support'), But sometimes, I get msg('General SQL Error,Invalid Rowid')
