# NULL attribute and DEFAULT NULL in columns

# let $col_definition = <column type (and possibly more options)>;
# let $col_default = <default non-null value for a column>;
# --source col_null.inc
#
# We will add NULL at the end of $col;
#
# Also, if $col_default is defined,
# we will create a table with 3 columns (one with DEFAULT NULL,
# one with DEFAULT $col_default, and one without any default)
