這篇文章主要介紹了Python使用win32com模塊實(shí)現(xiàn)數(shù)據(jù)庫表結(jié)構(gòu)自動(dòng)生成word表格的方法,結(jié)合實(shí)例形式分析了win32com模塊下載、連接mysql、查詢獲取表結(jié)構(gòu)以及使用win32com生成word表格的相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了Python使用win32com模塊實(shí)現(xiàn)數(shù)據(jù)庫表結(jié)構(gòu)自動(dòng)生成word表格的方法。分享給大家供大家參考，具體如下：

下載win32模塊

連接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()

獲取所有表結(jié)構(gòu)

#獲取表數(shù)據(jù)庫中所有表和備注
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
#獲取表結(jié)構(gòu)
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 #是否在后臺(tái)運(yùn)行word
word.DisplayAlerts = 0 #是否顯示警告信息
doc = word.Documents.Add() #新增一個(gè)文檔
r = doc.Range(0,0) #獲取一個(gè)范圍
r.Style.Font.Name = u"Verdana" #設(shè)置字體
r.Style.Font.Size = "9" #設(shè)置字體大小
r.InsertBefore("\n" + 表描述 + " " + 表名) #在這個(gè)范圍前插入文本
table = r.Tables.Add(doc.Range(r.End,r.End),字段數(shù)+1,5) #建一張表格
table.Rows[0].Cells[0].Range.Text = u"列"
table.Rows[0].Cells[1].Range.Text = u"類型"
table.Rows[0].Cells[2].Range.Text = u"默認(rèn)值"
table.Rows[0].Cells[3].Range.Text = u"是否為空"
table.Rows[0].Cells[4].Range.Text = u"列備注"

完整代碼

#coding:utf-8
#把數(shù)據(jù)庫中的表結(jié)構(gòu)導(dǎo)出到word的表格中，完成設(shè)計(jì)文檔
#不會(huì)用win32com操作word樣式

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"類型"
  table.Rows[0].Cells[2].Range.Text = u"默認(rèn)值"
  table.Rows[0].Cells[3].Range.Text = u"是否為空"
  table.Rows[0].Cells[4].Range.Text = u"列備注"
  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

希望本文所述對(duì)大家Python程序設(shè)計(jì)有所幫助。
