本文实例讲述了Python使用win32com模块实现数据库表结构自动生成word表格的方法。分享给大家供大家参考，具体如下：
下载win32模块
下载链接：https://sourceforge.net/projects/pywin32/files/pywin32/
连接mysql
import MySQLdb db_host = "" db_port = 3306 db_name = "" db_user = "" db_pwd = "" db = MySQLdb.connect(host=db_host,port=db_port,user=db_user,passwd=db_pwd,db=db_name,charset="utf8") cursor = db.cursor()
获取所有表结构
#获取表数据库中所有表和备注
def get_tables(cursor,db_name):
sql = "select table_name,table_comment from information_schema.tables where table_schema = '" + db_name + "'"
cursor.execute(sql)
result = cursor.fetchall()
tables = {}
for r in result:
tables[r[0]] = r[1]
return tables
#获取表结构
def get_table_desc(cursor,db_name,table_name):
sql = "select column_name,column_type,column_default,is_nullable,column_comment from information_schema.columns where table_schema = '" + db_name + "' and table_name = '" + table_name + "'"
cursor.execute(sql)
result = cursor.fetchall()
return result
win32com操作
from win32com.client import Dispatch,constants
word = Dispatch('Word.Application')
word.Visible = 1 #是否在后台运行word
word.DisplayAlerts = 0 #是否显示警告信息
doc = word.Documents.Add() #新增一个文档
r = doc.Range(0,0) #获取一个范围
r.Style.Font.Name = u"Verdana" #设置字体
r.Style.Font.Size = "9" #设置字体大小
r.InsertBefore("\n" + 表描述 + " " + 表名) #在这个范围前插入文本
table = r.Tables.Add(doc.Range(r.End,r.End),字段数+1,5) #建一张表格
table.Rows[0].Cells[0].Range.Text = u"列"
table.Rows[0].Cells[1].Range.Text = u"类型"
table.Rows[0].Cells[2].Range.Text = u"默认值"
table.Rows[0].Cells[3].Range.Text = u"是否为空"
table.Rows[0].Cells[4].Range.Text = u"列备注"
完整代码
#coding:utf-8
#把数据库中的表结构导出到word的表格中，完成设计文档
#不会用win32com操作word样式
