我建议使用mysql shell-下面的示例使用python模式:

mysqlsh> \py

mysql-py> i_s = session.get_schema("information_schema")

mysql-py> functions = i_s.ROUTINES \
       ->                .select("sys.quote_identifier(ROUTINE_SCHEMA) AS RoutineSchema", "sys.quote_identifier(ROUTINE_NAME) AS RoutineName") \
       ->                .where("ROUTINE_SCHEMA = 'db1' AND ROUTINE_TYPE = 'FUNCTION'").execute().fetch_all()

mysql-py> functions
[
    [
        "`db1`",
        "`func1`"
    ], 
    [
        "`db1`",
        "`func2`"
    ], 
    [
        "`db1`",
        "`func``3`"
    ]
]

mysql-py> for function in functions:
       ->     print(sql_fmt.format(*function))
       ->     session.sql(sql_fmt.format(*function)).execute()
       ->
DROP FUNCTION `db1`.`func1`
DROP FUNCTION `db1`.`func2`
DROP FUNCTION `db1`.`func``3`
Query OK, 0 rows affected (0.0684 sec)
