python连接mysql，自动生成数据库表对应的word文档（毕设福利）

运行程序后生成的word文档

安装两个依赖插件

pip install pymysql
pip install python-docx

#!/usr/bin/python3

# 引入依赖
import pymysql
from docx import Document
from docx.shared import Inches
from docx.enum.text import WD_ALIGN_PARAGRAPH
from docx.oxml.ns import nsdecls
from docx.oxml import parse_xml

# 打开数据库连接
db = pymysql.Connect(
    host='127.0.0.1',
    port=3306,
    user='root',
    passwd='root',
    db='zhufang',
    charset='utf8'
)

schema_name = input('数据库名：')

# 使用 cursor() 方法创建一个游标对象 cursor
cursor = db.cursor()

# 获取文档对象
document = Document()

# 获取所有要遍历的表名
cursor.execute('show tables')
tables = [n[0] for n in cursor.fetchall()]

# 循环数据库中的表
for t in tables:
    # 查询表的列名、数据类型、字符长度、是否允许空、默认值、备注信息
    cursor.execute(
        "SELECt COLUMN_NAME,DATA_TYPE,CHARACTER_MAXIMUM_LENGTH,IS_NULLABLE,COLUMN_DEFAULT, COLUMN_COMMENT FROM INFORMATION_SCHEMA.COLUMNS WHERe  table_schema ='%s'  AND table_name='%s'" % (
        schema_name, t))
    # 文档添加换行符
    document.add_paragraph()
    # 文档添加表名
    document.add_paragraph('表名：%s' % t)
    # 文档添加表格
    table = document.add_table(rows=1, cols=6)
    # 表格为灰色线条表格
    table.style = 'Table Grid'
    # 表格列宽度
    table.columns[0].width = Inches(0.49)
    # 表格第一行的属性赋值
    hdr_cells = table.rows[0].cells
    hdr_cells[0].add_paragraph('字段名').alignment = WD_ALIGN_PARAGRAPH.CENTER
    hdr_cells[1].add_paragraph('数据类型').alignment = WD_ALIGN_PARAGRAPH.CENTER
    hdr_cells[2].add_paragraph('长度').alignment = WD_ALIGN_PARAGRAPH.CENTER
    hdr_cells[3].add_paragraph('允许为空').alignment = WD_ALIGN_PARAGRAPH.CENTER
    hdr_cells[4].add_paragraph('默认值').alignment = WD_ALIGN_PARAGRAPH.CENTER
    hdr_cells[5].add_paragraph('描述').alignment = WD_ALIGN_PARAGRAPH.CENTER

    # 数据库游标获取各个数据库每个字段的各个属性，包括字符名称、数据类型、是否允许空、默认值、备注等信息
    table_fileds = cursor.fetchall()

    #对字段进行遍历，row为每个字段，下面的[0],[1]这些为获取到的属性，比如row_cell[0]获取的是字段名称，row_cell[1]获取的是数据类型
    for row in table_fileds:
        row_cells = table.add_row().cells
        row_cells[0].text = row[0]
        row_cells[1].text = row[1]
        row_cells[2].text = str(row[2])
        row_cells[3].text = row[3]
        row_cells[4].text = str(row[4])
        row_cells[5].text = row[5]
    # 输出处理的表以及其字段的各个属性
    print('正在处理数据库表: ' + t + '...')
    _fields = [list(map(str, f)) for f in table_fileds]
    print(_fields)
    # 首行加底纹
    shading_list = locals()
    for i in range(6):
        shading_list['shading_elm_' + str(i)] = parse_xml(
            r''.format(nsdecls('w'), bgColor='cccccc'))
        table.rows[0].cells[i]._tc.get_or_add_tcPr().append(shading_list['shading_elm_' + str(i)])


document.add_page_break()
document.save('demo.docx')
# 关闭数据库连接
db.close()

python main.py运行即可生成文档
