when I try to upgrade my superset, I use superset db upgrade, I ran into the error: ``` sqlalchemy.exc.IntegrityError: (pymysql.err.IntegrityError) (1062, "Duplicate entry 'xxxx' for key 'uq_saved_query_uuid'") [SQL: ALTER TABLE saved_query ADD CONSTRAINT uq_saved_query_uuid UNIQUE (uuid)] (Background on this error at: http://sqlalche.me/e/13/gkpj) ``` ### Environment Mysql-5.7.25 ### Additional context I went back to commit d7eb1d47: on 96e99fb176a0_add_import_mixing_to_saved_query.py, there is a line of code, which is obviously written for acceleration: ``` # Add uuids directly using built-in SQL uuid function add_uuids_by_dialect = { MySQLDialect: """UPDATE %s SET uuid = UNHEX(REPLACE(uuid(), "-", ""));""", PGDialect: """UPDATE %s SET uuid = uuid_in(md5(random()::text || clock_timestamp()::text)::cstring);""", } ``` I tried this line of code on my table with couple rows, it gives exact same uuid for each row. After I deleted this line of code, everything goes on well. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
