DATE datatype should accept only date. [message #230158] Wed, 11 April 2007 01:51 Go to next message

I am using oracle 10g ,my problem is DATE datetype should accept only date.It should not accept date with time from the user.
I am using nearly 200 tables,in that nearly 450 columns having DATE datatype.
For all 450 columns using trunc(xdate) or to_date(xdate,'dd-mon-yyyy') or to_char(xdate,'dd-mon-yyyy') is very difculty.
Is there any way to accept only date( by mistake if a user enters date with timestamp it should not accept) in the create table statement itself?

Add a check constraint:
SQL> create table t (mycol date check (mycol=trunc(mycol)));

Table created.

SQL> insert into t values (sysdate);
insert into t values (sysdate)
ERROR at line 1:
ORA-02290: check constraint (MICHEL.SYS_C008513) violated

SQL> insert into t values (to_date('01/01/2007','DD/MM/YYYY'));

1 row created.
