Question

DB：Oracle

我能够在sql dev和sql plus中执行以下语句：

select OUTPUT_DATA(123) from dual;

但是当我尝试在Python上执行此语句时，python崩溃

if database == 'oracle':
    conn_str = 'Provider=OraOLEDB.Oracle;Data Source=%s;User ID=%s;Password=%s;' % (dbserver, dbUID, dbPWD)    #oracle connection string
    try:
        conn = Dispatch('ADODB.Connection')
        conn.Open(conn_str)
        conn.Execute(sqlCommand)
        conn.Close()
        result = True
    except Exception as e:
        print(e)
        raise Exception('Failed to execute SQL with Excpetion: ' + str(e))

下面是python错误的屏幕截图

有谁知道为什么？

在Python中选择double函数（arg）
