this is the part of my code which i use for handle the querys,

@bot.callback_query_handler(func=lambda call: call.data == '8')
def upfornextripcmd(call):
userchatid = call.from_user.id
usertxt = call.message.text
mesid = call.message.message_id

mydb = mysql.connector.connect(
host="",
user="",
password="",
database="")

mycursor = mydb.cursor()

mycursor.execute("SELECT mesid FROM drcar1 WHERE drchatid = %s", (userchatid,))
mesid= mycursor.fetchone()[0]

try:
 message = bot.get_message(chat_id=userchatid, message_id=mesid)
 latitude = message.location.latitude
 longitude = message.location.longitude
 sql = ("UPDATE drcar1 SET drgeolocation=POINT(%s, %s) WHERE drchatid = %s")
 val = (latitude, longitude, userchatid)
 mycursor.execute(sql, val)
 mydb.commit()
 sql1=f"UPDATE drcar1 SET end = NULL WHERE drchatid='{userchatid}'"
 sql2=f"UPDATE drcar1 SET start = NULL WHERE drchatid='{userchatid}'"
 mycursor.execute(sql1,sql2)
 mydb.commit()
 bot.send_message(userchatid,"Your location updated successfully,please wait for requests,")


except:
    sql = f"DELETE FROM drcar1 WHERE drchatid = '{userchatid}'"
    mycursor.execute(sql)
    mydb.commit()
    sql = f"UPDATE users SET mood='1' WHERE chatid='{userchatid}'"
    mycursor.execute(sql)
    mydb.commit()

    drcarbtn=types.ReplyKeyboardMarkup(row_width=1)
    btnhome=types.KeyboardButton("Home")
    drcarbtn.add(btnhome)

    bot.send_message(userchatid,"Taxi/Driving/Car/Send your live location!Please",reply_markup=(drcarbtn))
