我正在用python从s3读取数据，并试图写入mysql数据库，但是在这样做的时候我遇到了一个错误。
非常感谢您的帮助！

from pandas.io import sql
import pymysql
from sqlalchemy import create_engine

engine = create_engine('mysql+pymysql://' + user + ':' + passw + '@' + host + ':' + str(port) + '/' + database , echo=False)

df.to_sql(con=engine, name='pna_data', if_exists='replace')

错误： InternalError: (pymysql.err.InternalError) (1059, "Identifier name 'Quantity at Regenersis India PVT LTD. Central warehouse - Bangalore' is too long") [SQL: '\nCREATE TABLE pna_data (\n\tindex BIGINT, \n\tService Order Code TEXT, \n\tVendor TEXT, \n\tTableauPSL TEXT, \n\tService Station TEXT, \n\tCustomer Name TEXT, \n\tCustomer Contact Number BIGINT, \n\tCustomer Mobile Number FLOAT(53), \n\tCustomer Email TEXT, \n\tOld IMEI 1 FLOAT(53), \n\tOld IMEI 2 FLOAT(53), \n\tIMEI 1 TEXT, \n\tIMEI 2 FLOAT(53), \n\tProduct Model TEXT, \n\tPurchase Date DATETIME, \n\tService Type TEXT, \n\tIsWarrantyApplicable TEXT, \n\tIs CID TEXT, \n\tCreate Time DATETIME, \n\tApply for Parts Time DATETIME, \n\tDOA TEXT, \n\tProblem Category TEXT, \n\tDefective Part PN FLOAT(53), \n\tDefective Part Name TEXT, \n\tReplacement Part PN FLOAT(53), \n\tReplacement Part Name TEXT, \n\tInventory Qty at Service center FLOAT(53), \n\tQuantity at B2X Mumbai Central warehouse FLOAT(53), \n\tQuantity at OnePlus - Bangalore Main Warehouse FLOAT(53), \n\tQuantity at Regenersis India PVT LTD.
