# rowid values, starting with 1, in the order that they are returned by

#
# Each test case below is specified as the name of a table to create
# using "CREATE TABLE ... AS SELECT ..." and a SELECT statement to use in
# creating it. The table is created.
#
# Test cases 2.4.*.1 check that after it has been created, the data in the
# table is the same as the data returned by the SELECT statement executed as
# a standalone command, verifying the first testable statement above.
#
# Test cases 2.4.*.2 check that the rowids were allocated contiguously
# as required by the second testable statement above. That the rowids
# from the contiguous block were allocated to rows in the order rows are
# returned by the SELECT statement is verified by 2.4.*.1.
