[GitBox <gi...@apache.org>]

zhangsikai123 opened a new issue #12202:
URL: https://github.com/apache/incubator-superset/issues/12202


   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.
