data chaned depending on condition

[Dong-iL, Kim]

Hello.

I’ve queried data as below.

select /*+ NO_INDEX */ * from WINLOSS where DAYNUMBER=?;

there are fields of null vaue.

after that I retrieve it with primary key again there is no null value.

select /*+ NO_INDEX */ * from WINLOSS where DAYNUMBER=? and GPID=? and TYPE=?;

what is check points to solve this problem?

Regards.
