Обсуждение: How To Create DATETIME Data Types in A Table

I am converting several databases from difference database vendors in PostgreSQL, but I am
finding that PostgreSQL appears to not support this datatype, unlike the other vendors we use.
The DATETIME fields coming from the other databases look like:
     '2005-01-27 15:55:04'
How do I get the same effect in Postgres CREATE TABLE statement without losing data?

That should correspond perfectly with the timestamp data type. See

http://www.postgresql.org/docs/8.0/interactive/datatype-datetime.html

As far is ensuring it is parsed correctly for import, look at the
DateStyle parameter.

In postgres you want to use timestamp with time zone. (Or perhaps timestamp
without time zone, depending on what the timestamp represents.)
