【Python】Python3连接Oracle数据库并查询数据

以下是Python3.7.4 连接Oracle 11g并查询数据的实例,代码如下:


import cx_Oracle
def main():
    # 1.建立连接
    conn = cx_Oracle.connect('scott', 'tiger', 'IP地址:1521/ORCL')

    # 2.创建游标
    cursor = conn.cursor()

    # 3.执行SQL
    res = cursor.execute('select empno,ename from emp')

    # 4.获取数据
    data = res.fetchall()
    for empno, ename in data:
        print('=' * 30)
        print("员工编号:" + str(empno), "员工姓名: " + ename)
    # 5.关闭游标
    cursor.close()

    # 6.关闭连接
    conn.close()

if __name__ == '__main__':
    main()
