problem insert time into column timestamp

do not use the time stamp field use time if you are doing a time instead
of a timestamp

and for the date use a pure date field

When working with Postgres, I receive an error when trying to insert a

gedis30=# create table pippo (aa timestamp)\g

gedis30=# insert into pippo (aa) values('10:12:12')\g
ERROR: Bad timestamp external representation '10:12:12'

How can I solve this problem ?

Hmm. That is a big jump to assume that a date/time value missing *all*
date information should default those fields to "today". Not supported
in standards at all afaik.

What is the behavior if you try entering in *no* information at all? Do
you get today's date at midnight? Does anyone know if other databases
have the same behavior?

Right. You can give it a hint:

lockhart=> select timestamp 'today 10:12:12';
timestamptz
------------------------
2002-08-01 10:12:12-07

But what is your use case? Do you have users entering in dates and you
want them to be able to skip the date fields if they know it is for
today? If so, you might think about having your application preload the
date fields with correct values??

Problem to execute insert command.

gedis30=# insert into pippo (aa) values(cast ('10:12:12' as time));
ERROR: column "aa" is of type 'timestamp with time zone' but expression is of type 'time without time zone'
You will need to rewrite or cast the expression

You should specify in the table declaration
