用Python 将excel 导入Mysql 时遭遇报错: '<' not supported between instances of 'str' and 'int'

  • python

各位高手大家好:

在尝试使用Python语句将 工作用excel 导入本机的Mysql 时,需要将"EOL By"字段被Python识别成数字。
为了将其转化成可接受的日期型的形式,我使用了xlrd.xldate_as_datetime()的方法,随即报错: '<' not supported between instances of 'str' and 'int' 。 我想不明白:分明之前使用了同样方法的initiation date可以正常转化成日期型显示,而EOL By"字段就显示报错了

以下是我的代码:

import xlrd
import pymysql
import xlrd

# 打开excel----------------------------------------------------------
def open_excel():
    try:
        book = xlrd.open_workbook('C:/Users/lenovo/Desktop/工作纪录就靠它了.xlsx')  #文件名,把文件与py文件放在同一目录下
    except:
        print("open excel file failed!")
    try:
        sheet = book.sheet_by_name('ANZ纪录')   #execl里面的worksheet1
        return sheet
    except:
        print("locate worksheet in excel failed!")

# 验证:open_excel 是跑的通的
#-----------------------------------------------------------------


#连接数据库-------------------------------------------------------
try:
    db = pymysql.connect(host='localhost',user="root",
        passwd='QAZwsx12345678',
        db='test',
        charset='utf8')
except:
    print("could not connect to mysql server")
# 验证:本机数据库连接 是跑的通的
#----------------------------------------------------------------
def search_count():
    cursor = db.cursor()
    select = "select count(PN) from pn_infor" #获取表中xxxxx记录数
    cursor.execute(select) #执行sql语句
    line_count = cursor.fetchone()
    print(line_count[0])

#验证:search_count 是可以跑通的
#-----------------------------------------------------------------

def insert_deta():
    sheet = open_excel()
    cursor = db.cursor()
    for i in range(5, sheet.nrows): #第一行是标题名,对应表中的字段名所以应该从第二行开始,计算机以0开始计数,所以值是1

        inidate = sheet.cell(i,0).value #取第i行第0列
        initiation_date = xlrd.xldate_as_datetime(inidate,0) # 把数字型的日期解码成真正的日期
        requestor = sheet.cell(i,1).value#取第i行第1列,下面依次类推
        EB  = sheet.cell(i,2).value
        EOL_By = initiation_date = xlrd.xldate_as_datetime(EB,0) # 把数字型的日期解码成真正的日期
        customer_name = sheet.cell(i,3).value
        Type_of_Service = sheet.cell(i,4).value
        PN = sheet.cell(i,5).value
        description30 = sheet.cell(i,6).value
        description80 = sheet.cell(i,7).value
        Enable = sheet.cell(i,8).value
        CostUSD = sheet.cell(i,9).value
        CostAUD = sheet.cell(i,10).value
        ListpriceAUD = sheet.cell(i,11).value
        DistipriceAUD = sheet.cell(i,12).value


        print(initiation_date)
        print(requestor)
        print(EOL_By)
        print(customer_name)
        print(Type_of_Service)
        print(PN)
        print(description30)
        print(description80)
        print(Enable)
        print(CostUSD)
        print(CostAUD)
        print(ListpriceAUD)
        print(DistipriceAUD)
        print("---------------")


        value = (initiation_date,requestor,EOL_By,customer_name,Type_of_Service,PN,description30,description80,Enable,CostUSD,CostAUD,ListpriceAUD,DistipriceAUD)
        print(value)
        sql = "INSERT INTO pn_infor(initiation_date,requestor,EOL_By,customer_name,Type_of_Service,PN,description30,description80,Enable,CostUSD,CostAUD,ListpriceAUD,DistipriceAUD)VALUES(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)"
        cursor.execute(sql,value) #执行sql语句
        db.commit()
    cursor.close() #关闭连接



insert_deta()

db.close()#关闭数据
print ("ok ")
