<p>The INSERT statement comes in two basic forms. The first form

If no column-list is specified then the number of values must
be the same as the number of columns in the table. If a column-list
is specified, then the number of values must match the number of
specified columns. Columns of the table that do not appear in the
column list are fill with the default value, or with NULL if not
default value is specified.
</p>
<p>The second form of the INSERT statement takes it data from a
SELECT statement. The number of columns in the result of the
SELECT must exactly match the number of columns in the table if
no column list is specified, or it must match the number of columns
name in the column list. A new entry is made in the table
for every row of the SELECT result. The SELECT may be simple
or compound. If the SELECT statement has an ORDER BY clause,
the ORDER BY is ignored.</p>
