I'm attempting to drop a unique constraint on MySQL 5.6.20, 64-bit, Python 2.7.6, SQLA 0.9.7, Alembic 0.6.6:
The table's very simple: CREATE TABLE `author` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(75) CHARACTER SET utf8 NOT NULL, `foo` varchar(100) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4; But when I attempt to drop the unique constraint on foo using op. drop_constraint(u'uq_author_foo', 'author', type_='unique'), I get an error: https://gist.github.com/urschrei/541fec05a3a82d71cbe9 Manually removing it, both on the command line and in Sequel Pro, works fine. -- s -- You received this message because you are subscribed to the Google Groups "sqlalchemy-alembic" group.
