gbrian commented on issue #2422: Create migrate script failed URL: https://github.com/apache/incubator-superset/issues/2422#issuecomment-498684843 Hi, Having the issue: ``` sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) near "ALTER": syntax error [SQL: ALTER TABLE annotation ALTER COLUMN layer_id SET NOT NULL] ``` It happens without any change. `layer_id` column at `annotation` table is defined: `layer_id = Column(Integer, ForeignKey('annotation_layer.id'), nullable=False) ` Question: Is it save to commit the generated script? If not what's the preferred DB engine for development? Currently using **sqlite3**
