python⾃动⽣成sql语句的脚本

描述:

⼯作中在数据库中创建表时,当字段很多时,⽐较⿇烦,开发⼀个⼯具,可在excel中写好字段英⽂名和中⽂名,然后通过py⽣成脚本或直接在库中⽣成表脚本:

import tkinter

from tkinter import *

import tkinter.messageboxfrom tkinter import scrolledtextimport xlrd

import pymysqlimport os

#从excel中获取字段项,组合建表语句def get_create_sql(dir_path, file_name): try:

# 打开xls⽂件

#excel_path = \"%s%s\" % (dir_path, file_name) #print(\"excel_path:\

wb = xlrd.open_workbook(filename=dir_path) # 打开第⼀sheet ws = wb.sheets()[0] #获取⾏列数量 nrows = ws.nrows #ncols = ws.ncols #获取sheet1的名称 table_name = ws.name #print(\"nrows:\ #print(\"ncols:\

#print(\"sheet1_name:\ #xlrd中⾏列是从0开始的 for i in range(nrows):

if i == 0: #字段英⽂,格式是列表 row0_data = ws.row_values(0) #print(row0_data)

if i == 1: #字段中⽂,格式是列表 row1_data = ws.row_values(1) #print(row1_data) #将含有-字符的替换

header0 = [str(i).replace(\"-\ #print(\"header0:\

header1 = [str(i).replace(\"-\ #print(\"header1:\ #获取表名

table_commet = file_name.split(\".\")[0] #print(\"table_name:\

create_sql = \"CREATE TABLE `%s` (\\n\" % table_name #print(\"create_sql:\ header0_len = len(header0)

#print(\"header0_len:\ for i in range(header0_len):

#print(\"i:\ if i < header0_len-1:

create_sql += \"`%s` varchar(255) DEFAULT NULL COMMENT '%s',\\n\" % (header0[i], header1[i]) if i == header0_len-1:

create_sql += \"`%s` varchar(255) DEFAULT NULL COMMENT '%s'\\n\" % (header0[i], header1[i]) create_sql += \") ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='%s';\\n\" % table_commet #print(\"[INFO]:[create_sql]\ except BaseException as e: #print(\"[ERRO]:\

tkinter.messagebox.showerror('错误', str(e)) return create_sql

def to_db(create_sql,hostname,hostport,username,userpasswd,dbname): #链接数据库,执⾏

#print(hostname,hostport,username,userpasswd,dbname) try:

db = pymysql.connect(host=hostname, port=hostport, user=username, passwd=userpasswd, db=dbname) cursor = db.cursor()

cursor.execute(create_sql) cursor.fetchall() db.close()

#print(\"表创建成功!\")

tkinter.messagebox.showinfo('提⽰', '表创建成功 !') except BaseException as e: #print(\"表创建失败!\

tkinter.messagebox.showerror('错误', str(e))

# get 变量内容def show_db():

if v1.get() == '' or v2.get() == '' or v3.get() == '' or v4.get() == '' or v5.get() == '' or v6.get() == '': tkinter.messagebox.showinfo('提⽰', '请先输⼊内容 !') return

if v1.get() == 'token**123':

tkinter.messagebox.showinfo('提⽰', 'author by lijiyan 2020-12-03,Thank you.') return

#print(\"⽂件路径名 :%s\" % e1.get()) #print(\"数据库IP :%s\" % e2.get()) #print(\"数据库端⼝ :%s\" % e2.get()) #print(\"库名 :%s\" % e2.get()) #print(\"⽤户名 :%s\" % e2.get()) #print(\"密码 :%s\" % e2.get()) #easygui.msgbox('执⾏完成 !') dir_pathname = e1.get()

#dir_pathi = os.path.dirname(dir_pathname) file_namei = os.path.basename(dir_pathname) #print(dir_pathname,file_namei)

create_sql = get_create_sql(dir_path=dir_pathname, file_name=file_namei )

to_db(create_sql=create_sql, hostname=e2.get(), hostport=int(e3.get()), dbname=e4.get(), username=e5.get(), userpasswd=e6.get() )

def show_sql(): if v1.get() == '':

tkinter.messagebox.showinfo('提⽰', '请先输⼊内容 !') return

#print(\"⽂件路径名 :%s\" % e1.get()) dir_pathname = e1.get()

# dir_pathi = os.path.dirname(dir_pathname) file_namei = os.path.basename(dir_pathname) # print(dir_pathname,file_namei)

create_sql = get_create_sql(dir_path=dir_pathname, file_name=file_namei )

#tkinter.messagebox.showinfo('提⽰', create_sql) t.delete(1.0, END)

t.insert('insert', create_sql) #e8.insert('insert',create_sql) #这个可以,但样式难看

#Label(top, text=create_sql,wraplength=200).grid(row=8,column=0,sticky=W+E+N+S,padx=5,pady=5,rowspan=7,columnspan=2)#初始框的声明top = tkinter.Tk()

top.title(\"⽣成createsql⼯具v1.0\")top.geometry(\"400x300+300+200\")

## 标签控件,对Label内容进⾏ 表格式 布局

Label(top,text='⽂件路径名 :').grid(row=0, column=0)Label(top,text='数据库IP :').grid(row=2,column=0)Label(top,text='数据库端⼝ :').grid(row=3,column=0)Label(top,text='库名 :').grid(row=4,column=0)Label(top,text='⽤户名 :').grid(row=5,column=0)Label(top,text='密码 :').grid(row=6,column=0)#Label(top,text='sql :').grid(row=0,column=1)#定义变量

v1 = StringVar()v2 = StringVar()v3 = StringVar()v4 = StringVar()v5 = StringVar()

v6 = StringVar()#v8 = StringVar()

# 输⼊控件,⽤于储存 输⼊的内容e1 = Entry(top, textvariable=v1)e2 = Entry(top, textvariable=v2)e3 = Entry(top, textvariable=v3)e4 = Entry(top, textvariable=v4)e5 = Entry(top, textvariable=v5)

e6 = Entry(top, textvariable=v6, show=\"*\")#e8 = Entry(top, textvariable=v8)

# 进⾏表格式布局

e1.grid(row=0,column=1,padx=10,pady=5)e2.grid(row=2,column=1,padx=10,pady=5)e3.grid(row=3,column=1,padx=10,pady=5)e4.grid(row=4,column=1,padx=10,pady=5)e5.grid(row=5,column=1,padx=10,pady=5)e6.grid(row=6,column=1,padx=10,pady=5)

#e8.grid(row=0,column=2,sticky=W+E+N+S,padx=5,pady=5,rowspan=7,columnspan=2)#⽂本内容较⼤,滚动⽂本框,展⽰⽂本内容

t = scrolledtext.ScrolledText(top,width = 20,height = 20,wrap=WORD)t.grid(row=0,column=2,rowspan=7,columnspan=2)

# 设置 button 指定 宽度 , 并且 关联 函数 , 使⽤表格式布局 .

Button(top,text='⽣成sql',width=10,command=show_sql).grid(row=1,column=1,sticky=E,padx=10,pady=5)Button(top,text='⼊库',width=10,command=show_db).grid(row=7,column=1,sticky=W,padx=10,pady=5)Button(top,text='退出',width=10,command=top.quit).grid(row=7,column=1,sticky=E,padx=10,pady=5)mainloop()

打包⽣成⼯具:在资源栏

excel说明:

第⼀⾏,表字段英⽂名称第⼆⾏,表字段中⽂名称第三⾏,表数据,可不写
