import sqlite3
from xlsxwriter.workbook import Workbook
workbook = Workbook('output2.xlsx')
worksheet = workbook.add_worksheet()

conn=sqlite3.connect('test.sqlite')
c=conn.cursor()
c.execute("select * from abc")
mysel=c.execute("select * from abc ")
for row in mysel:
 print row
 worksheet.write(0, 0, row[0])
workbook.close()

这是 SQLITE 数据库表的布局

id  sno
1   100
2   200
3   300
4   400

使用 worksheet.write(0, 0, row[0]) 我在 excel 文件的第一个单元格中得到输出为4。

使用 worksheet.write(0, 0, row[1]) 我在 excel 文件的第一个单元格中得到400的输出

我无法弄清楚FOR LOOP问题。

请帮忙

您的循环很好，只是您将每行数据写入同一个单元格。我不知道 xlswriter 但我猜第一个和第二个参数是行和列。如果要将所有数据写入表，则需要在每次写入操作时更改这些数据。

像这样的东西（未经测试）？

import sqlite3
from xlsxwriter.workbook import Workbook
workbook = Workbook('output2.xlsx')
worksheet = workbook.add_worksheet()

conn=sqlite3.connect('test.sqlite')
c=conn.cursor()
c.execute("select * from abc")
mysel=c.execute("select * from abc ")
for i, row in enumerate(mysel):
    print row
    worksheet.write(i, 0, row[0])
    worksheet.write(i, 1, row[1])
workbook.close()

要处理多个列，您可以这样做

import sqlite3
from xlsxwriter.workbook import Workbook
workbook = Workbook('output2.xlsx')
worksheet = workbook.add_worksheet()

conn=sqlite3.connect('test.sqlite')
c=conn.cursor()
c.execute("select * from abc")
mysel=c.execute("select * from abc ")
for i, row in enumerate(mysel):
    for j, value in enumerate(row):
        worksheet.write(i, j, value)
workbook.close()

您可以创建一个包含许多工作表的 XLSX 文件，而不是在同一个文件中创建许多 CSV 工作表。根据您的需求，它可能是一个很好的解决方案。这就是我所拥有的。

import sqlite3
import xlsxwriter
from tkinter import filedialog # Used to get a path where to save the new excel file
from datetime import datetime # Used to name the file with today's date

DB_Path = filedialog.askdirectory() # OPTIONAL: Asks to select folder path
workbook = xlsxwriter.Workbook(DB_Path+"/"+"MyDatabaseInExcel  "+datetime.now().strftime("%Y %m %d")+'.xlsx') # Create file
conn = sqlite3.connect('MyDatabaseInSQLite3.db') # Connect to your database
cursor = conn.cursor() # Create the cursor
tables = list(cursor.execute("SELECT name FROM sqlite_master WHERE type='table';")) # Get all table names
tables = list(map(lambda x: x[0], tables)) # convert the list of tuple to list of str
for table in tables:
    try: worksheet = workbook.add_worksheet(name=table[0:31]) # Sheet names in excel can have up to 31 chars
    except:pass
    for row_number, row in enumerate(cursor.execute('SELECT * FROM '+table)): # row is a tuple here
        for column_number, item in enumerate(row):
            try: worksheet.write(row_number, column_number, item) # Write the cell in the current sheet
            except:pass
workbook.close() # Saves the new document

我尝试了一些尝试，以防止出于任何原因破解程序，而不是编写其他工作表。对我来说，在我的项目中曾经很有趣。如果你想，你不能使用它。
