    The INSERT statement comes in two basic forms. The first form +(with the "VALUES" keyword) creates a single new row in an existing table. +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. +

    + +

    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.
