# NULL attribute and DEFAULT NULL in columns
|
|
#
|
|
# Usage:
|
|
# 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)
|
|
