>   A column can be assigned a default value.  When a new row is
   created and no values are specified for some of the columns, the
   columns will be filled with their respective default values.  A
   data manipulation command can also request explicitly that a column
   be set to its default value, without knowing what this value is.
   (Details about data manipulation commands are in <A
HREF="dml.html"
>Chapter 6</A
>.)
  </P

>
   If no default value is declared explicitly, the null value is the
   default value.  This usually makes sense because a null value can
   be thought to represent unknown data.
  </P
><P
>   In a table definition, default values are listed after the column
   data type.  For example:
</P><PRE
CLASS="PROGRAMLISTING"
>CREATE TABLE products (
    product_no integer,
    name text,
    price numeric <B
CLASS="EMPHASIS"
>DEFAULT 9.99</B
>
);</PRE
><P>
  </P
><P
>   The default value may be a scalar expression, which will be
   evaluated whenever the default value is inserted
   (<SPAN
CLASS="emphasis"
><I
CLASS="EMPHASIS"
>not</I
></SPAN
> when the table is created).
