-# |
-# 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. |
