实例一：插入数据

import pymysql
import tkinter as tk

conn = pymysql.connect(host='localhost', user='root', passwd='root', db='okzl', charset='utf8')

master = tk.Tk()
master.title("插入供应商信息")
master.geometry('350x300')
tk.Label(master, text='cName').place(x=30,y=10)
tk.Label(master, text='address').place(x=30,y=40)
tk.Label(master, text='linkman').place(x=30,y=70)
tk.Label(master, text='linkPhone').place(x=30,y=100)
tk.Label(master, text='credit').place(x=30,y=130)
tk.Label(master, text='remark').place(x=30,y=160)
in1=tk.Entry(master, width=30).place(x=100,y=10)
in2=tk.Entry(master, width=30).place(x=100,y=40)
in3=tk.Entry(master, width=30).place(x=100,y=70)
in3=tk.Entry(master, width=30).place(x=100,y=100)
in3=tk.Entry(master, width=30).place(x=100,y=130)
in3=tk.Entry(master, width=30).place(x=100,y=160)

def insert():
    cur = conn.cursor()  # 伸出手
    sql1 = "insert into pro(cName,address,linkman,linkPhone,credit,remark) values(%s,%s,%s,%s,%s,%s)"
    temp2 = ( )
    cur.execute(sql1, temp2)
    conn.commit()
    cur.close()

tk.Button(master,text='插入',width=8,command=insert).place(x=140,y=220)

master.mainloop()
conn.close()

成功插入数据

实例二：获取某个表全部数据

import pymysql

conn = pymysql.connect(host='localhost', user='root', passwd='root', db='okzl', charset='utf8')
cur = conn.cursor()

cur.execute('select * from pro')
data = cur.fetchall()

cur.close()
print(data)
conn.close()

实例三：根据cName模糊搜索

import pymysql
import tkinter as tk

conn = pymysql.connect(host='localhost', user='root', passwd='root', db='okzl', charset='utf8')  # 连接数据库

master = tk.Tk()
master.title("搜索某客户信息")
master.geometry('350x300')

e = tk.Entry(master)
e.pack(padx=20, pady=20)


def tosearch():
    cur = conn.cursor()
    temp2 = (e.get(), "%" + e.get() + "%")
    cur.execute("select * from pro where cName like %s or cName like %s ", temp2)
    data = cur.fetchall()
    cur.close()
    print(data)


tk.Button(master, text='搜索', width=8, command=tosearch).pack(padx=20, pady=50)

master.mainloop()

conn.close()

实例四：修改数据

根据数据库自动给数据生成的id来确认目标和修改数据

import pymysql
import tkinter as tk

conn = pymysql.connect(host='localhost', user='root', passwd='root', db='okzl', charset='utf8')

master = tk.Tk()
master.title("修改供应商信息")
master.geometry('350x300')
tk.Label(master, text='cName').place(x=30,y=10)
tk.Label(master, text='address').place(x=30,y=40)
tk.Label(master, text='linkman').place(x=30,y=70)
tk.Label(master, text='linkPhone').place(x=30,y=100)
tk.Label(master, text='credit').place(x=30,y=130)
tk.Label(master, text='remark').place(x=30,y=160)
tk.Label(master, text='目标id').place(x=30,y=190)
in1=tk.Entry(master, width=30)
in1.place(x=100,y=10)
in2=tk.Entry(master, width=30)
in2.place(x=100,y=40)
in3=tk.Entry(master, width=30)
in3.place(x=100,y=70)
in4=tk.Entry(master, width=30)
in4.place(x=100,y=100)
in5=tk.Entry(master, width=30)
in5.place(x=100,y=130)
in6=tk.Entry(master, width=30)
in6.place(x=100,y=160)
in7=tk.Entry(master, width=30)
in7.place(x=100,y=190)

def update():
    cur = conn.cursor()  # 伸出手
    sql1 = "update pro set cName=%s, address=%s,linkman=%s,linkPhone=%s,credit=%s,remark=%s where id=%s"
    temp2 = (in1.get(),in2.get(),in3.get(),in4.get(),in5.get(),in6.get(),in7.get())
    cur.execute(sql1, temp2)
    conn.commit()
    cur.close()


tk.Button(master,text='确认修改',width=8,command=update).place(x=140,y=220)

master.mainloop()
conn.close()

实例五：删除数据

这里是根据id删除

sql1 = "delete from pro where id=%s"
temp1 = str(n)
cur.execute(sql1, temp1)
conn.commit()
cur.close()

上述实例均为基础实现操作举例，实际操作中可根据需求更改程序和sql语句实现目标效果
