# Test Organization:
#
# analyze3-1.*: Test that the values of bound parameters are considered 
#               in the same way as constants when planning queries that
#               use range constraints.
#
# analyze3-2.*: Test that the values of bound parameters are considered 
#               in the same way as constants when planning queries that
#               use LIKE expressions in the WHERE clause.
#
# analyze3-3.*: Test that binding to a variable does not invalidate the 
#               query plan when there is no way in which replanning the
#               query may produce a superior outcome.
#
# analyze3-4.*: Test that SQL or authorization callback errors occuring
#               within sqlite3Reprepare() are handled correctly.
#
# analyze3-5.*: Check that the query plans of applicable statements are
#               invalidated if the values of SQL parameter are modified
#               using the clear_bindings() or transfer_bindings() APIs.
# 
# analyze3-6.*: Test that the problem fixed by commit [127a5b776d] is fixed.

# analyze3-1.1.1: 
#   Create a table with two columns. Populate the first column (affinity 
#   INTEGER) with integer values from 100 to 1100. Create an index on this 
#   column. ANALYZE the table.
#
# analyze3-1.1.2 - 3.1.3
#   Show that there are two possible plans for querying the table with
#   a range constraint on the indexed column - "full table scan" or "use 
#   the index". When the range is specified using literal values, SQLite
#   is able to pick the best plan based on the samples in sqlite_stat3.
#
# analyze3-1.1.4 - 3.1.9
#   Show that using SQL variables produces the same results as using
#   literal values to constrain the range scan.
#
#   These tests also check that the compiler code considers column 
#   affinities when estimating the number of rows scanned by the "use 
#   index strategy".
