Python连接达梦数据库的实现示例

# coding:utf-8
import dmPython

try:
    # 创建达梦数据库连接
    conn = dmPython.connect(user='TEST', password='abc123456', server='localhost',
                            port=5236)
    # 创建数据库操作对象
    cursor = conn.cursor()
    # try:
    #     # 清空表，初始化测试环境
    #     cursor.execute('delete from T2')
    # except (dmPython.Error, Exception) as err:
    #     print(err)
    try:
        # 插入数据
        # cursor.execute("insert into DMHR.EMPLOYEE (EMPLOYEE_ID,EMPLOYEE_NAME,EMAIL,HIRE_DATE,JOB_ID) values(1157, '马云','888888888@qq.com','2023-05-12','42')")
        # print('python: insert success!')

        # # 更新数据
        # cursor.execute("update DMHR.EMPLOYEE set EMPLOYEE_NAME = '刘强东' where EMPLOYEE_ID = 1157")
        # print('python: update success!')

        # 查询数据
        cursor.execute("select id from test.SYSTEMS_USER")
        res = cursor.fetchall()
        for tmp in res:
            for c1 in tmp:
                print(c1)
        print('python: select success!')

        # # 删除数据
        # cursor.execute("delete from DMHR.EMPLOYEE where EMPLOYEE_ID = 1157")
        # print('python: delete success!')
        #


    except (dmPython.Error, Exception) as err1:
        print(err1)
    conn.close()
