# For MySQL, every statement ends with a `;\n` (that's a semicolon followed by
# a newline), and it cannot parse the next if a new statement follows after an
# indentation, like we normally write for other backends. So breaking apart the
# requests into individual statements turned out to be the ergonomic way to make
# this work.
#
# Also tried typical YAML multi-line (block) syntax in all combinations `|`,
# `>` with `+` and `-`, including specification of the indentation levels with
# numbers, without success.
#
# NOTE: For local development, if manual data seeding is ever necessary, we
# maintain a `mysql-ddl-dml.sql` that should always remain in sync with this
# file.

# NOTE on dropping tables that have dependent views:
# ref: https://dev.mysql.com/doc/refman/5.7/en/view-restrictions.html
#
# You can use DROP TABLE or ALTER TABLE to drop or alter a table that is used
# in a view definition. No warning results from the DROP or ALTER operation,
# even though this invalidates the view. Instead, an error occurs later, when
# the view is used. CHECK TABLE can be used to check for views that have been
# invalidated by DROP or ALTER operations.
