尝试使用python将数据导入MySQL时，出现“ SQL语句中未使用所有参数”错误

Question

I am trying to scrape data from a website and upload it into MySQL database. But I keep getting the error:

"Not all parameters were used in the SQL statement".

Here is the code:

player_stats = []
table = soup.find('tbody')
table_row = table.findAll('tr')
for row in table_row:
    td = row.findAll('td')
    if td:
        player_dict = {}
        player_dict['POS'] = td[0].string
        player_dict['NAME'] = td[1].a.string
        player_dict['G'] = td[3].string
        player_dict['AB'] = td[4].string
        player_dict['AVG'] = td[16].string
        for k, v in player_dict.items():
            if player_dict[k] is None:
                player_dict[k] = "-"
        player_stats.append(player_dict)

player_stats = json.dumps(player_stats)

cursor = db.cursor()

cursor.executemany("""
    INSERT INTO test (pos, name, g, ab, avg)
    VALUES (%(POS)s, %(NAME)s, %(G)s, %(AB)s, %(AVG)s)""", player_stats)

db.commit()

Here is the data in the player_stats list that I am trying to INSERT INTO the database:

[{"POS": "C", "NAME": "Jeff Mathis", "G": "69", "AB": "218", "AVG": ".200"}, {"POS": "1B", "NAME": "Paul Goldschmidt", "G": "158", "AB": "690", "AVG": ".290"}, {"POS": "2B", "NAME": "Ketel Marte", "G": "153", "AB": "580", "AVG": ".260"}, {"POS": "SS", "NAME": "Nick Ahmed", "G": "153", "AB": "564", "AVG": ".234"}, {"POS": "3B", "NAME": "Jake Lamb", "G": "56", "AB": "238", "AVG": ".222"}, {"POS": "LF", "NAME": "David Peralta", "G": "146", "AB": "614", "AVG": ".293"}, {"POS": "CF", "NAME": "A.J.

I have searched all over the site for hours and can't find where I'm going wrong. I'm quite new to working with MySQL and Python, so it might be something simple that I'm overlooking. All help is greatly appreciated.

Answer 1

I'm not familiar with the %(COL)s syntax, so I'm assuming you can't do that (but I'm not sure).

Also, the args requirement is generally supposed to be either a list or a list of lists, and not a list of dictionaries.

changing the following should fix your problem:

player_stats = [['pos','name','g','ab','avg'], ... ]

sql = 'INSERT INTO test (pos, name, g, ab, avg) VALUES (%s, %s, %s, %s, %s)'

cursor.executemany(sql, player_stats)
