Python使用win32com模块实现数据库表结构自动生成word表格的方法

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
import MySQLdb,config
from win32com.client import Dispatch,constants
db_name = "crawlerdb_update"
db = MySQLdb.connect(host=config.db_host,port=config.db_port,user=config.db_user,passwd=config.db_pwd,db=db_name,charset="utf8")
cursor = db.cursor()
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
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
tables = get_tables(cursor,db_name)
word = Dispatch('Word.Application')
word.Visible = 1 
word.DisplayAlerts = 0 
doc = word.Documents.Add()
r = doc.Range(0,0)
r.Style.Font.Name = u"Verdana"
r.Style.Font.Size = "9"
for k,table_name in enumerate(tables):
  tables_desc = get_table_desc(cursor,db_name,table_name)
  print r.Start
  r.InsertBefore("\n" + tables[table_name] + " " + table_name)
  table = r.Tables.Add(doc.Range(r.End,r.End),len(tables_desc) + 1,5)
  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"
  for i,column in enumerate(tables_desc):
    for j,col in enumerate(column):
      if col == None:
        col = "(NULL)"
      table.Rows[i+1].Cells[j].Range.Text = col
  r = doc.Range(table.Range.End,table.Range.End)
  break
