<p>The DEFAULT clause specifies a default value to use for the column if no
value is explicitly provided by the user when doing an [INSERT]. ^If there
is no explicit DEFAULT clause attached to a column definition, then the 
default value of the column is NULL. ^(An explicit DEFAULT clause may specify
that the default value is NULL, a string constant, a blob constant, a
signed-number, or any constant expression enclosed in parentheses. An explicit
default value may also be one of the special case-independent keywords
CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP.)^ ^For the purposes of the
DEFAULT clause, an expression is considered constant provided that it does
not contain any sub-queries, column or table references, or string literals
enclosed in double-quotes instead of single-quotes.

does not provide explicit values for all table columns the values stored in
the new row are determined by their default values)^, as follows:
