    As far I could see, you dont have autoincrement primary key or foreign key.
    If you dont have tables with foreign key or relation between, first you can list all your tables. After that, you can create a temporal “mirror” of one table (for eg, autogrill).
    Then you can do a:

    INSERT INTO TemporalTable
SELECT DISTINCT

    or a

    INSERT INTO TemporalTable
SELECT Id, Date, Time FROM autogrill GROUP BY Id, Date, Time HAVING COUNT(*) > 1

    .

    TRUNCATE or DELETE FROM

    without where and then put again your data with

    INSERT INTO autogrill
SELECT * FROM TemporalTable

    BE AWARE if you have primary keys doing this.
