# 3.3 Views
#     MySQL views are based on a subset of the view requirements described in
#     the following standard SQL document:
#
#     * ISO/IEC 9075-2:2003 Information technology -- Database languages --
#       SQL -- Part 2: Foundation (SQL/Foundation)
#
#     MySQL has also added some vendor-specific enhancements to the standard
#     SQL requirements.

# FIXME (ML)
#   - Alter all object names so that they follow the v/t/..<number> scheme or
#     apply another method which prevents that customer data might be
#     accidently modified
#   - Remove any reference to the preloaded tables tb1 - tb4, if they could
#     be replaced without loss of value.
#     Example: failing CREATE VIEW statements
#     The goal is to split this script into two, where the first one does
#     not need the possibly huge tables.

# Load records needed within the testcases.
#     We load them here and not within the testcases itself, because the
#     removal of any unneeded testcase during bug analysis should not alter
#     result sets.
