#-------------------------------------------------------------------------
|
|
# Test structure:
|
|
#
|
|
# fkey2-1.*: Simple tests to check that immediate and deferred foreign key
|
|
# constraints work when not inside a transaction.
|
|
#
|
|
# fkey2-2.*: Tests to verify that deferred foreign keys work inside
|
|
# explicit transactions (i.e that processing really is deferred).
|
|
#
|
|
# fkey2-3.*: Tests that a statement transaction is rolled back if an
|
|
# immediate foreign key constraint is violated.
|
|
#
|
|
# fkey2-4.*: Test that FK actions may recurse even when recursive triggers
|
|
# are disabled.
|
|
#
|
|
# fkey2-5.*: Check that if foreign-keys are enabled, it is not possible
|
|
# to write to an FK column using the incremental blob API.
|
|
#
|
|
# fkey2-6.*: Test that FK processing is automatically disabled when
|
|
# running VACUUM.
|
|
#
|
|
# fkey2-7.*: Test using an IPK as the key in the child (referencing) table.
|
|
#
|
|
# fkey2-8.*: Test that enabling/disabling foreign key support while a
|
|
# transaction is active is not possible.
|
|
#
|
|
# fkey2-9.*: Test SET DEFAULT actions.
|
|
#
|
|
# fkey2-10.*: Test errors.
|
|
#
|
|
# fkey2-11.*: Test CASCADE actions.
|
|
#
|
|
# fkey2-12.*: Test RESTRICT actions.
|
|
#
|
|
# fkey2-13.*: Test that FK processing is performed when a row is REPLACED by
|
|
# an UPDATE or INSERT statement.
|
|
#
|
|
# fkey2-14.*: Test the ALTER TABLE and DROP TABLE commands.
|
|
#
|
|
# fkey2-15.*: Test that if there are no (known) outstanding foreign key
|
|
# constraint violations in the database, inserting into a parent
|
|
# table or deleting from a child table does not cause SQLite
|
|
# to check if this has repaired an outstanding violation.
|
|
#
|
|
# fkey2-16.*: Test that rows that refer to themselves may be inserted,
|
|
# updated and deleted.
|
|
#
|
|
# fkey2-17.*: Test that the "count_changes" pragma does not interfere with
|
|
# FK constraint processing.
|
|
#
|
|
# fkey2-18.*: Test that the authorization callback is invoked when processing
|
|
# FK constraints.
|
|
#
|
|
# fkey2-20.*: Test that ON CONFLICT clauses specified as part of statements
|
|
# do not affect the operation of FK constraints.
|
|
#
|
|
# fkey2-genfkey.*: Tests that were used with the shell tool .genfkey
|
|
# command. Recycled to test the built-in implementation.
|
|
#
|
|
# fkey2-dd08e5.*: Tests to verify that ticket dd08e5a988d00decc4a543daa8d
|
|
# has been fixed.
