实例一:插入数据
实例二:获取某个表全部数据
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') 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
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()
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()
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()
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()
