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