mysql生成数据库字典文档

项目交付离不开项目数据库字典文档。下面用python轻松生成交付文档字典。

一 生成doc文档数据库字典效果：

1 生成doc文件，如下图：

2 打开文件字典格式内容 ，如下图：

二 python生成doc字典文档代码

  生成doc数据库字典python代码：

import docx
import os
from docx import Document #导入库 python-docx
import pymysql




def exportDbInfoWord (path):
    host = 'xx.xx.xx.xx'
    connect = pymysql.connect(host=host, user='user', password='xxxxx', db='information_schema')
    db ='dbname'
    cur = connect.cursor()

    cur.execute("""SELECT

    -- T.TABLE_SCHEMA AS '数据库名称',

     T.TABLE_NAME AS '表名',

    -- T.TABLE_TYPE AS '表类型',

    -- C.ORDINAL_POSITION AS '字段编号',

    C.COLUMN_NAME AS '字段名',

    C.COLUMN_TYPE AS '数据类型',

    C.IS_NULLABLE AS '允许为空',

    document = Document()

    # rowcount = cur.rowcount

    i = 1

        table.add_row()
        table.cell(i, 0).text = u[1]
        table.cell(i, 1).text = u[2]
        table.cell(i, 2).text = u[3]
        table.cell(i, 3).text = u[4]
        i = i + 1

    document.save(path)


if __name__ == '__main__':
    path = 'D:/数据库字典.docx'
    exportDbInfoWord(path);
    print('完成')
