我正在尝试使用pyhdb执行简单查询。
这是我的代码：
HDB_TRACE=1
import pyhdb as db
db.tracing = True
connection = db.connect('HOST', 31047, 'USER', 'PASSWORD')
cursor = connection.cursor()
cursor.execute("SELECT TOP 1 GLOBAL_BRAND_OWNER FROM _SYS_BIC.LAV_DWH_SELLOUT.CV_NIELSEN")
print(cursor.fetchone())
我得到的错误是pyhdb.exceptions.DatabaseError: insufficient privilege: Not authorized
我向DB管理员询问，他告诉我，我登录的用户有各种特权。
如果我尝试SELECT 'Hello Python World' FROM DUMMY就可以了。我不知道我的代码是否有错误。
如果我使用相同的用户执行查询和Hana Studio，它可以正常工作。
这是过程的痕迹：

我会说很明显，你的用户确实没有“所有可能的特权”。 看到您尝试访问计算视图，我的第一个猜测是您的用户没有对该计算视图的授权。
要对问题进行更全面的分析，您可以通过SAP HANA Studio登录，右键单击视图并选择“显示授权”。 这将为您提供所需和提供的权限的图形概述。
这个blog post对如何使用该工具提供了很好的报道。

您必须设置登录HANA数据库的游标对象的参数，并确保用户拥有包含您正在查询的数据的架构的权限。
