Getting an error while using Cast function

try adding a colon after the year
31-AUG-2003:00:00:00.00

I tried adding COLON after Year part ....
It stiil gives the same error.
I am not sure that the way i am using CAST function is correct.
See the error below(after putting COLON):

declare :p_char char(23);

declare :p_date date vms;

begin

set :p_char = '31-AUG-2003:00:00:00.00';

set :p_date = cast(:p_char as date vms);

end;

I forgot to add Error message:

SQL>
SQL> declare :p_date date vms;
SQL>
SQL> begin

cont> set :p_char = '31-AUG-2003:00:00:00.00';

cont>
cont> end;

Check your RDB doc : is the function for date + time or only date ?

I have used this function for both date as well as Date + time....
It gives error in both cases.

Its not preciser than seconds. Remove ".00".

I'm no SQL expert, but IMHO you don't need the "cast".

SQL> declare :p_date date vms;
SQL> begin
cont> set :p_date='31-AUG-2003';
cont> end;
SQL> print :p_date;
P_DATE
31-AUG-2003 00:00:00.00

remove .00 also gives the same error. Can u tell me if i can use Cast function the way i am doing it right now. IF Not then tell me how can casting be achieved.

[waliamanish]

Kris, U have already declared P_date as date type...
My objective is to convert String to date.
