將CSV數據插入MySQL數據庫-“您的SQL語法有誤；在第1行的''附近

Question

這是我得到的確切錯誤消息：

(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1")

這是我的代碼。

def mysql_connect():
    conn = MySQLdb.connect(host = "localhost",
                           user = "root",
                           passwd = "********",
                           db = "seomonster")
    cursor = conn.cursor()

    filename = 'tdnam_all_listings.csv'
    filename2 = 'tdnam_all_listings2.csv'
    filename3 = 'tdnam_all_listings3.csv'

    try:
        table_create = """CREATE TABLE sites (domainName CHAR(40),
itemID INT,auctionType CHAR(40),
timeLeft CHAR(40),
price CHAR(20),
bids INT,
domainAge INT,
traffic INT,
valuationPrice CHAR(40))"""
        cursor.execute(table_create)

    except Exception as e:
        print e


    try:
        csv_data = csv.reader(file(filename))
        for row in csv_data:
            cursor.execute("""INSERT INTO sites(domainName,itemID,auctionType,timeLeft,price,bids,domainAge,traffic,valuationPrice)""")
    except Exception as e2:
        print e2

    conn.commit()
    cursor.close()
    conn.close()

我完全不理解該錯誤，盡管我認為它與我通過插入數據使用的SQL語法有關？

@bernie將我的代碼更改為此：

cursor.execute("""INSERT INTO sites(domainName,itemID,auctionType,timeLeft,price,bids,domainAge,traffic,valuationPrice) values (%s%s,%s,%s,%s,%s,%s,%s,%s);""")

現在出現此錯誤：

(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s%s,%s,%s,%s,%s,%s,%s,%s)' at line 1") 

@VMai我按照您的建議，將代碼更改為：

for row in csv_data:
    insert = """INSERT INTO sites (domainName,itemID,auctionType,timeLeft,price,bids,domainAge,traffic,valuationPrice) values (%s,%s,%s,%s,%s,%s,%s,%s,%s);"""
    cursor.execute(insert,(row[0],row[1],row[2],row[3],row[4],row[5],row[6],row[7],row[8]))

我遇到了一個很長的錯誤，我認為這與％s的某些列有關都是整數，這就是我認為的原因。 錯誤：

  File "/var/www/seomonster/ZeroPain.py", line 109

Answer 1

我想您在第一個查詢參數%s之后只缺少一個逗號，因為您有9個字段要填寫，但最后只有8個參數。 由於第一和第二個%s之間缺少逗號，因此它們將被連接起來。

第二，如注釋中所述，將您的參數作為第二個參數傳遞給此函數。

嘗試這個：

cursor.execute("""INSERT INTO sites (domainName,itemID,auctionType,timeLeft,price,bids,domainAge,traffic,valuationPrice) values (%s,%s,%s,%s,%s,%s,%s,%s,%s);""", (row[0],row[1],row[2],row[3],row[4],row[5],row[6],row[7],row[8]))
