Python异步操作MySQL第三方库zdpapi_mysql入门教程，增删改查实在是太方便了
zapi_mysql
基于异步的快速操作MySQL的组件
项目源码地址：https://github.com/zhangdapeng520/zdpapi_mysql
使用pip安装
pip install zapi_mysql
一、增删改数据
1.1 创建表
import asyncio
from zapi_mysql import Mysql
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
async def test_example_execute(loop):
# 删除表
await db.connect()
sql = "DROP TABLE IF EXISTS user;"
# 创建表
await db.execute(sql)
sql = """CREATE TABLE user
(id INT,
name VARCHAR(255),
PRIMARY KEY (id));"""
await db.execute(sql)
# 插入SQL语句
sql = "INSERT INTO user VALUES(1,'张三')"
await db.execute(sql)
loop = asyncio.get_event_loop()
loop.run_until_complete(test_example_execute(loop))
1.2 插入数据
import asyncio
from zapi_mysql import Mysql
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
async def test_example_execute(loop):
# 插入SQL语句
sql = "INSERT INTO user VALUES(2,'李四')"
await db.execute(sql)
loop = asyncio.get_event_loop()
loop.run_until_complete(test_example_execute(loop))
1.3 批量插入数据
import asyncio
from zapi_mysql import Mysql
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
async def test_example_execute(loop):
# 插入SQL语句
data = [(4, 'gothic metal'), (5, 'doom metal'), (6, 'post metal')]
sql = "INSERT INTO user VALUES(%s,%s)"
await db.execute(sql, data=data)
loop = asyncio.get_event_loop()
loop.run_until_complete(test_example_execute(loop))
二、查询数据
2.1 查询所有数据
import asyncio
from zapi_mysql import Mysql
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
async def test_example_execute(loop):
# 插入SQL语句
sql = "SELECT id, name FROM user ORDER BY id"
result = await db.execute(sql)
print("查询结果：\n", result)
loop = asyncio.get_event_loop()
loop.run_until_complete(test_example_execute(loop))
2.2 查询单条数据
import asyncio
from zapi_mysql import Mysql
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
async def test_example_execute(loop):
# 查询单条数据
sql = "SELECT id, name FROM user ORDER BY id"
result = await db.execute(sql, return_all=False)
print("查询结果：\n", result)
loop = asyncio.get_event_loop()
loop.run_until_complete(test_example_execute(loop))
三、CRUD快捷工具
3.1 新增用户
import asyncio
from zdpapi_mysql import Mysql, Crud
db = Mysql(host='127.0.0.1',
port=3306,
user='root',
password='root',
db='test')
crud = Crud(db, "user", ["name"])
async def test_create_table(loop):
# 删除表
await db.connect()
sql = "DROP TABLE IF EXISTS user;"
# 创建表
await db.execute(sql)
sql = """CREATE TABLE user(id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(255));"""
await db.execute(sql)
# 插入SQL语句
sql = "INSERT INTO user VALUES(1,'张三')"
await db.execute(sql)
async def test_insert(loop):
# 插入SQL语句
await crud.add("李四")
await crud.add("王五")
await crud.add("赵六")
if __name__ == "__main__":
loop = asyncio.get_event_loop()
loop.run_until_complete(test_create_table(loop))
loop.run_until_complete(test_insert(loop))
3.2 添加多条数据

async def test_create_table(loop):
# 删除表
await db.connect()
sql = "DROP TABLE IF EXISTS user;"
# 创建表
await db.execute(sql)
sql = """CREATE TABLE user(id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(255));"""
await db.execute(sql)
# 插入SQL语句
sql = "INSERT INTO user VALUES(1,'张三')"
await db.execute(sql)
async def test_insert(loop):
# 插入SQL语句
await crud.add("李四")
await crud.add("王五")
await crud.add("赵六")
async def test_insert_many(loop):
# 插入SQL语句
data = [("孙悟空",), ("猪八戒",), ("沙僧",), ]
await crud.add_many(data)
if __name__ == "__main__":
loop = asyncio.get_event_loop()
loop.run_until_complete(test_create_table(loop))
loop.run_until_complete(test_insert(loop))
