# Checks of some basic properties of the INFORMATION_SCHEMA which are not
# related to a certain INFORMATION_SCHEMA table.
#
# This test should not check properties related to storage engines.

# Author:
# 2008-01-23 mleich WL#4203 Reorganize and fix the data dictionary tests of
# testsuite funcs_1
# Create this script based on older scripts and new code.

# This test is strict adjusted to the behaviour of the non embedded server.
# Example of common differences between both servers:
# USE information_schema; CREATE VIEW tables AS SELECT 'garbage';
# non embedded server:
# - errname ER_DBACCESS_DENIED_ERROR
# - ERROR 42000: Access denied for user 'root'@'localhost' to
# database 'information_schema'
# embedded server:
# - errno 1
# - Can't create/write to file
