Using date in a check constraint, Oracle -

-

i trying check add following constraint oracle returns error shown below.

alter table table1 add (constraint gt_table1_closedate check (closedate > sysdate), constraint lt_table1_closedate check (closedate <= sysdate + 365)), constraint gt_table1_startdate check (startdate > (closedate + (sysdate + 730))));

error:

error report: sql error: ora-02436: date or system variable wrongly specified in check constraint 02436. 00000 -  "date or system variable wrongly specified in check constraint" *cause:    attempt made use date constant or system variable,            such user, in check constraint not            specified in create table or alter table statement.             example, date specified without century. *action:   specify date constant or system variable.            setting event 10149 allows constraints "a1 > '10-may-96'",            bug permitted created before version 8.

a check constraint, unfortunately, cannot reference function sysdate. need create trigger checked these values when dml occurs, i.e.

create or replace trigger trg_check_dates   before insert or update on table1   each row begin   if( :new.closedate <= sysdate )       raise_application_error( -20001,            'invalid closedate: closedate must greater current date - value = ' ||            to_char( :new.closedate, 'yyyy-mm-dd hh24:mi:ss' ) );   end if;   if( :new.closedate > add_months(sysdate,12) )       raise_application_error( -20002,           'invalid closedate: closedate must within next year - value = ' ||           to_char( :new.closedate, 'yyyy-mm-dd hh24:mi:ss' ) );   end if;   if( :new.startdate <= add_months(:new.closedate,24) )       raise_application_error( -20002,            'invalid startdate: startdate must within 24 months of closedate - startdate = ' ||            to_char( :new.startdate, 'yyyy-mm-dd hh24:mi:ss' ) ||           ' closedate = ' || to_char( :new.closedate , 'yyyy-mm-dd hh24:mi:ss' ) );   end if; end;
