#
# NOT NULL attribute in columns
#
# Usage:
# let $col_definition = <column type (and possibly more options)>;
# let $col_default = <default non-null value for a column>;
# --source col_not_null.inc
#
# We will add NOT NULL at the end of $col;
#
# Also, if $col_default is defined, 
# we will create a table with 2 columns 
# (one with DEFAULT $col_default, and one without any default), 
# and will also attempt to add a column with DEFAULT NULL.
