一、添加方法

db = pymysql.connect(host='localhost',user='root',password='123456',db='python')
cursor = db.cursor()
sql ="""
    insert into EMPLOYEE
    VALUES
    ('3','张','天爱',35,'F',8000)
"""
try:
    cursor.execute(sql)
    db.commit() #提交后，数据才会变
except:
    db.rollback()#数据异常时，回滚
db.close()

结果

二、修改

db = pymysql.connect(host='localhost',user='root',password='123456',db='python')
cursor = db.cursor()
sql ="""
    update EMPLOYEE set INCOME=18000 where EMPLOYEE_ID=1
"""
try:
    cursor.execute(sql)
    db.commit()
except:
    db.rollback()
db.close()

结果

三、删除

db = pymysql.connect(host='localhost',user='root',password='123456',db='python')
cursor = db.cursor()
sql ="""
    delete from EMPLOYEE  where EMPLOYEE_ID=1
"""
try:
    cursor.execute(sql)
    db.commit()
except:
    db.rollback()
db.close()

结果

四、查找

db = pymysql.connect(host='localhost',user='root',password='123456',db='python')
cursor = db.cursor()
sql ='select * from employee'
try:
    cursor.execute(sql)
    results = cursor.fetchall()
    for row in results:
        print(row)
        fname = row[1]
        lname = row[2]
        age = row[3]
        sex = row[4]
        income = row[5]
        print(f'我是{fname}{lname},今天{age}岁了,性别是{sex},工资是{income}')
except:
   print('查询数据出错')
db.close()

结果
