11 # This file implements regression tests for SQLite library.

13 # This file tests the various conditions under which an SQLITE_SCHEMA
14 # error should be returned. This is a copy of schema.test that
15 # has been altered to use sqlite3_prepare_v2 instead of sqlite3_prepare

20 # When any of the following types of SQL statements or actions are
21 # executed, all pre-compiled statements are invalidated. An attempt
22 # to execute an invalidated statement always returns SQLITE_SCHEMA.

24 # CREATE/DROP TABLE...................................schema2-1.*
25 # CREATE/DROP VIEW....................................schema2-2.*
26 # CREATE/DROP TRIGGER.................................schema2-3.*
27 # CREATE/DROP INDEX...................................schema2-4.*
28 # DETACH..............................................schema2-5.*
29 # Deleting a user-function............................schema2-6.*
30 # Deleting a collation sequence.......................schema2-7.*
31 # Setting or changing the authorization function......schema2-8.*
32 #
33 # Test cases schema2-9.* and schema2-10.* test some specific bugs
34 # that came up during development.
35 #
36 # Test cases schema2-11.* test that it is impossible to delete or
37 # change a collation sequence or user-function while SQL statements
38 # are executing. Adding new collations or functions is allowed.
