Question

我试图一次将数百行插入MySQL数据库。记录有两种类型，未接电话和已接电话。我将所有记录放入一个元组列表中，每个记录都是它自己的元组，以便可以使用executemany函数。我收到一个TypeError：不是在字符串格式化期间转换了所有参数，而且我不明白为什么。

answered = []
        unanswered = []
        insertQuery =             """ INSERT INTO cdr (recno, relcause, starttime, answertime, endtime, releasecausetext, releasecausecode, 1streleasedialog,
                                      origtrunk, callingnumber, orighost, callednumber, desthost, origcallid, origremotepayloadip, origremotepayloadport,

        for y in cdrList:
            #Check to make sure record does not exist
            sqlQuery = "select * from cdr where recno = %d and origcallid = %s;" % (int(y[0]), y[13])
            if cursor.execute(sqlQuery):
                print("Record exists")
            else:
                if y[7]=='NA':
                    unanswered.append((y[0], y[5],extractSqlDate(y[6]), 'null',  extractSqlDate(y[8]), y[10], y[11], y[12], y[13], y[15], y[16], y[17], y[18], y[19], y[20], y[21], y[22], y[23], y[32], y[34], y[35], y[36], y[37], y[38], y[39], y[40], y[41], y[42], y[53], y[54], y[55], y[56], y[60], y[66], y[67], y[71], y[78], y[79], y[80], y[81], y[85], y[88]))
                else:
                    answered.append((y[0], y[5],extractSqlDate(y[6]), extractSqlDate(y[7]), extractSqlDate(y[8]), y[10], y[11], y[12], y[13], y[15], y[16], y[17], y[18], y[19], y[20], y[21], y[22], y[23], y[32], y[34], y[35], y[36], y[37], y[38], y[39], y[40], y[41], y[42], y[53], y[54], y[55], y[56], y[60], y[66], y[67], y[71], y[78], y[79], y[80], y[81], y[85], y[88]))
        try:
            print(answered)
            cursor.executemany(insertQuery, answered)
            cursor.executemany(insertQuery, unanswered)
            db.commit()
            print("Record inserted successfully")
        except MySQLdb.Error as e:
            print(e)

我已经确认列表中每个元组中的每个元素都是一个字符串：

Answer 1

我发现了问题。元组正在返回字符串，因此insert查询试图插入这样的值：“ value”。我删除了％s周围的'，然后根据@jonrsharpe的评论，为每个其他值添加了％s，它起作用了。

具有字符串的元组列表，并非在格式化字符串时转换了所有参数
