# EVIDENCE-OF: R-36924-43758 By default, every row in SQLite has a
# special column, usually called the "rowid", that uniquely identifies
# that row within the table.
#
# EVIDENCE-OF: R-32341-39358 However if the phrase "WITHOUT ROWID" is
# added to the end of a CREATE TABLE statement, then the special "rowid"
# column is omitted.

# EVIDENCE-OF: R-00217-01605 To create a WITHOUT ROWID table, simply add
