# Tests in this file are organized roughly as follows:
#
# types2-1.*: The '=' operator in the absence of an index.
# types2-2.*: The '=' operator implemented using an index.
# types2-3.*: The '<' operator implemented using an index.
# types2-4.*: The '>' operator in the absence of an index.
# types2-5.*: The 'IN(x, y...)' operator in the absence of an index.
# types2-6.*: The 'IN(x, y...)' operator with an index.
# types2-7.*: The 'IN(SELECT...)' operator in the absence of an index.
# types2-8.*: The 'IN(SELECT...)' operator with an index.
#
# All tests test the operators using literals and columns, but no
# other types of expressions. All expressions except columns are
# handled similarly in the implementation.
