- update to 1.8.1:
* Fixed bug where the SQLite implementation of
:meth:`.Operations.rename_table` would render an explicit schema name for
both the old and new table name, which while is the standard ALTER syntax,
is not accepted by SQLite's syntax which doesn't support a rename across
schemas. In particular, the syntax issue would prevent batch mode from
working for SQLite databases that made use of attached databases (which are
treated as "schemas" in SQLAlchemy).
* Added an error raise for the condition where
:meth:`.Operations.batch_alter_table` is used in ``--sql`` mode, where the
operation requires table reflection, as is the case when running against
SQLite without giving it a fixed ``Table`` object. Previously the operation
would fail with an internal error. To get a "move and copy" batch
operation as a SQL script without connecting to a database,
a ``Table`` object should be passed to the
:paramref:`.Operations.batch_alter_table.copy_from` parameter so that
reflection may be skipped.
