27 # fkey2-1.*: Simple tests to check that immediate and deferred foreign key
28 # constraints work when not inside a transaction.
30 # fkey2-2.*: Tests to verify that deferred foreign keys work inside
31 # explicit transactions (i.e that processing really is deferred).
33 # fkey2-3.*: Tests that a statement transaction is rolled back if an
34 # immediate foreign key constraint is violated.
36 # fkey2-4.*: Test that FK actions may recurse even when recursive triggers
39 # fkey2-5.*: Check that if foreign-keys are enabled, it is not possible
40 # to write to an FK column using the incremental blob API.
42 # fkey2-6.*: Test that FK processing is automatically disabled when
45 # fkey2-7.*: Test using an IPK as the key in the child (referencing) table.
47 # fkey2-8.*: Test that enabling/disabling foreign key support while a
48 # transaction is active is not possible.
50 # fkey2-9.*: Test SET DEFAULT actions.
52 # fkey2-10.*: Test errors.
54 # fkey2-11.*: Test CASCADE actions.
56 # fkey2-12.*: Test RESTRICT actions.
58 # fkey2-13.*: Test that FK processing is performed when a row is REPLACED by
59 # an UPDATE or INSERT statement.
61 # fkey2-14.*: Test the ALTER TABLE and DROP TABLE commands.
63 # fkey2-15.*: Test that if there are no (known) outstanding foreign key
64 # constraint violations in the database, inserting into a parent
65 # table or deleting from a child table does not cause SQLite
66 # to check if this has repaired an outstanding violation.
68 # fkey2-16.*: Test that rows that refer to themselves may be inserted,
69 # updated and deleted.
71 # fkey2-17.*: Test that the "count_changes" pragma does not interfere with
72 # FK constraint processing.
74 # fkey2-18.*: Test that the authorization callback is invoked when processing
77 # fkey2-20.*: Test that ON CONFLICT clauses specified as part of statements
78 # do not affect the operation of FK constraints.
80 # fkey2-genfkey.*: Tests that were used with the shell tool .genfkey
81 # command. Recycled to test the built-in implementation.
