Question

我正在尝试通过mysql表数据在Excel工作表中插入数据。

'Feedstock', 'None', 'Naphtha', '5.00000', '2005', 'Y'
'Feedstock', 'None', 'Naphtha', '0.00000', '2006', 'Y'
'Feedstock', 'None', 'Naphtha', '0.00000', '2007', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2008', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2012', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2014', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2015', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2016', 'Y'
'Feedstock', 'None', 'Naphtha', '5.00000', '2017', 'Y'
'Building Blocks', 'Olefins', 'Ethylene', '5.00000', '2005', 'Y'
'Building Blocks', 'Olefins', 'Ethylene', '5.00000', '2006', 'Y'

喜欢此表，并希望将此数据填写到Excel工作表中。

excel格式为：

                                    2005-Y  2006-Y  2007-Y  2008-Y  2009-Y  2010-Y  2011-Y  2012-Y  2013-Y  2014-Y  2015-Y  2016-Y  2017-Y 2018-Y 2019-Y

Feedstock                 Naphtha   5   0   0   5   -   -   -   5   -   5   5   5   5 - -
Building Blocks (a)Olefine Ethylene 5   5   5   5   -   -   -   5   -   2.5 2.5 2.5 2.5 - -
                          Propylene 5   5   5   5   -   -   -   5   -   2.5 2.5 2.5 2.5 - - 
                          Butadiene 5   5   5   5   -   -   -   5   -   2.5 2.5 2.5 2.5 - -

我尝试过：

import pymysql
from xlsxwriter.workbook import Workbook
from openpyxl import load_workbook
import openpyxl
from openpyxl.styles import  Alignment, Font


sqlconn = ".............."
cursor = sqlconn.cursor()


wb = load_workbook('cpm_auto.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')

max_col = (sheet.max_column)
max_row = (sheet.max_row)

for row in range(3,max_row):
    for col in range(4,max_col):
        periods = sheet.cell(row = 1,column = col).value
        period = periods.replace('-Y','')
        val = sheet.cell(row = row,column = 3).value
        if val == 'Naphtha':
            query = "select Value from CPMAI where Product = '%s' and Year = '%s'" %(val,period)
            result = cursor.execute(query)

            if result > 0:
                values = cursor.fetchone()
                if len(values) > 0:
                    prev_value = values[0]
                    print(prev_value)
                    sheet.cell(row = row,column = col).value = values[0]
                else:

                    sheet.cell(row=row, column=col).value = prev_value
    break

wb.save('cpm_auto.xlsx')

我的代码：我尝试了此代码，但是此代码插入了具有值的年份的值，但是我想插入2005-2019年的所有年份值。请参阅excel格式，没有2009、2010、2011、2013、2018、2019的值，因此想要将前一年的值结转到该年。

我不知道您数据库中的数据是什么。如果您遵循以下示例，则可以

public function endScreen():void
        {
            //removeEventListener(Event.EXIT_FRAME, endLoad);



            ENDScore.text = "Score: " + String(scoreBar);

            ENDScore.width = 200;
            var endFormating:TextFormat = new TextFormat();
            endFormating.size = 25;
            endFormating.font = "Consolas";
            endFormating.color= 0xFFFFFF;
            ENDScore.x = stage.stageWidth/2 - ENDScore.width/2 + 10;
            ENDScore.y = 415;
            ENDScore.setTextFormat(endFormating);
            endBtn.x = 660;
            endBtn.y = 460;
            endBtn.scaleX = 0.9;
            endBtn.scaleY = 0.9;
            addChild(endScr);
            addChild(ENDScore);
            addChild(endBtn);
            closeDetect();
            //trace("button");
            //trace(scoreBar);
        }

        public function closeDetect(e:Event = null):void {

            trace("button");
            endBtn.addEventListener(MouseEvent.CLICK, closeGame);
        }

        public function closeGame(e:Event):void
        {
            //trace("button found");
            //
                //trace("button clicked");
                ////endBtn.visible = false;
                //removeChild(enemyFighter);
                //removeChild(enemyFighter2);
                //removeChild(enemyFighter3);
                //removeChild(enemyFighter4);
                //removeChild(enemyFighter5);
                //removeChild(lMass1);
                //removeChild(lMass2);
                //removeChild(player);
                ////removeChild(bullet);
                //removeChild(endScr);
                //removeChild(endBtn);
                //removeChild(ENDScore);
                //
                //playerDeath = false;
                //thePlayerDies = 3;
                //scoreBar = 0;
                //removeEventListener(MouseEvent.CLICK, closeGame);
                ////init();
                //if (stage) init();
                //else addEventListener(Event.ADDED_TO_STAGE, init); 
                fscommand("quit");

        }

我会在创建Excel工作表之前进行计算。例如（如果表不是太大）：

import pandas as pd
import numpy as np

# Load table into a DataFrame, see https://stackoverflow.com/questions/12047193
query = "select * from CPMAI"
result = cursor.execute(query)
df = pd.DataFrame(result.fetchall())
df.columns = result.keys()

pivot = df.pivot_table(values=["value"], index=["product"], columns=["year"], aggfunc=np.sum)

稍后，您可以遍历枢轴元素并填充Excel工作表
