Обсуждение: NULLs on datetime problem (for me at least :) )

Hi there,

I am having problems loading data into a datetime field when
the table allows NULL for the date.

I assume I am doing something silly. Can anyone help me?
Preferably technical rather than medical :)

Cheers

steve



# here is my test table.

--    Test table.

CREATE TABLE MyTable
(
    myName                       varchar(50)          NOT NULL,
    myDate                       datetime             NULL
);


# here is my datafile, with empty date data

si> cat datafile

# here is the table is Postgres

mydb=# \d mytable
                 Table "mytable"
 Attribute |           Type           | Modifier
-----------+--------------------------+----------
 myname    | character varying(50)    | not null
 mydate    | timestamp with time zone |


# here is the copy line I was trying.

mydb=# COPY mytable FROM '/home/si/datafile' USING DELIMITERS '|';
ERROR:  copy: line 1, Bad timestamp external representation ''

Represent nulls by \N in your input file. An empty string is not the
same.
