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

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