><P
> The <B
CLASS="COMMAND"
>insert</B
> statement is used to populate a class with
instances:
<PRE
CLASS="PROGRAMLISTING"
>INSERT INTO weather
VALUES ('San Francisco', 46, 50, 0.25, '11/27/1994')</PRE
> </P
><P
> You can also use the <B
CLASS="COMMAND"
>copy</B
> command to perform load large
amounts of data from flat (<SPAN
CLASS="ACRONYM"
>ASCII</SPAN
>) files.
This is usually faster because the data is read (or written) as a single atomic
transaction directly to or from the target table. An example would be:
<PRE
CLASS="PROGRAMLISTING"
>COPY INTO weather FROM '/home/user/weather.txt'
USING DELIMITERS '|';</PRE
>
where the path name for the source file must be available to the backend server
machine, not just the client. </P
