python - 属性错误 : 'MySQLCursor' object has no attribute 'commit'

Question

def fillblast(sequentie, titel_lijst, score_lijst, e_lijst, iden_lijst, pos_lijst, gaps_lijst): 
    conn = mysql.connector.connect(host = "ithurtswhenip.nl", user = "pg2", password = "pg2", database= "pg2", port= "3307") 
    cursor = conn.cursor()
    Blast = 1000
    for i in range(0,len(titel_lijst)):
        Blast =+ 2
        cursor.execute("INSERT INTO `pg2`.`Blast` (`Blast_id`, `Blast_seq`, `Blast_titel`, `Blast_score`, `Blast_E`, `Blast_gaps`, `Blast_pos`, `Blast_iden`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s);", (Blast, sequentie[i] ,titel_lijst[i], score_lijst[i], e_lijst[i], iden_lijst[i], pos_lijst[i], gaps_lijst[i]))
        print("1 record toegevoegd")
    cursor.commit()
    cursor.close() 
    conn.close()

我收到以下错误:

AttributeError: 'MySQLCursor' object has no attribute 'commit'

它是怎么来的，哪里出了问题？我尝试连接 MySQLWorkbench。

编辑:

现在我得到以下错误:

mysql.connector.errors.DatabaseError: 1205 (HY000): Lock wait timeout exceeded; try restarting transaction

Answer 1

因为你不能提交游标!您必须提交连接。

# cursor.commit() --> This is wrong!
conn.commit()  # This is right
