INSERT SELECT * FROM ON DUPLICATE Результаты с ошибкой 1136

Question

Я пытаюсь вставить/обновить df в таблицу mysql. Я получаю эту ошибку

"_mysql_exceptions.OperationalError: (1136, "Column count doesn't match value count at row 1")"

на строке выполнения в приведенном ниже коде. Любые предложения по обходному пути или более эффективному пути?

db = MySQLdb.connect(
    host = "myhost", 
    user = "username", 
    passwd = "password", 
    db = "mydb", 
    charset='utf8' 
) 

df.to_sql(con=db, name='t', if_exists='replace', flavor='mysql') 

sqlStatement = """INSERT INTO db.films SELECT t.* FROM db.t 
      ON DUPLICATE KEY UPDATE 
      films.releasedP=t.releasedP, 
      films.runtimeP=t.runtimeP, 
      films.imdbRatingP=t.imdbRatingP, 
      films.votesYearP=t.votesYearP, 
      films.years=t.years, 
      films.votesYear=t.votesYear 
      ;""" 

cursor = db.cursor() 
cursor.execute(sqlStatement) 
db.commit() 

Это схема таблиц, в которые я пытаюсь вставить/обновить данные.

Answer 1

Схемы таблиц db.films и db.t не совпадают. Поэтому вам нужно определить, какие столбцы таблицы db.films будут установлены в значение, указанное в таблице ``.

Попробуйте этот запрос:

INSERT INTO db.films (
    Title, 
    imdbID, 
    Released, 
    Runtime, 
    imdbRating, 
    imdbVotes, 
    releasedDateTime, 
    maxDateTime, 
    years, 
    votesYear, 
    rating, 
    runtimeF, 
    releasedP, 
    runtimeP, 
    imdbRatingP, 
    votesYearP 
) 
SELECT 
    Title, 
    imdbID, 
    Released, 
    Runtime, 
    imdbRating, 
    imdbVotes, 
    releasedDateTime, 
    maxDateTime, 
    years, 
    votesYear, 
    rating, 
    runtimeF, 
    releasedP, 
    runtimeP, 
    imdbRatingP, 
    votesYearP 
FROM db.t 
ON DUPLICATE KEY UPDATE 
    films.releasedP=t.releasedP, 
    films.runtimeP=t.runtimeP, 
    films.imdbRatingP=t.imdbRatingP, 
    films.votesYearP=t.votesYearP, 
    films.years=t.years, 
    films.votesYear=t.votesYear
