| # 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.
 | |
| #
 | |
| # analyze3-7.*: Test that some memory leaks discovered by fuzz testing 
 | |
| #               have been fixed.

| #   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.

| #   literal values to constrain the range scan.
 | |

| #   These tests also check that the compiler code considers column
