Python中的SQL查询

我试图在python中运行查询，但遇到了错误

我对SQL非常熟悉，我们的一位DBA编写了这个SQL命令，它在他们的机器上运行。然而，当我将其转换为Python时，我遇到了一些问题

import requests
from orionsdk import SwisClient

npm_server = 'SERVER'
username = 'USERNAME'
password = 'PASSWORD'

verify = False
if not verify:
    from requests.packages.urllib3.exceptions import InsecureRequestWarning
    requests.packages.urllib3.disable_warnings(InsecureRequestWarning)


swis = SwisClient(npm_server, username, password)

print("Query Test:")

query = """
SELECT NodesData.Caption as NodeName, IP_Address,
Interfaces.InterfaceName,
Interfaces.Status, Interfaces.InterfaceLastChange
 FROM Interfaces
 INNER JOIN NodesData ON Interfaces.NodeID = NodesData.NodeID
 INNER JOIN NodesCustomProperties (NOLOCK) ON NodesData.NodeID = NodesCustomProperties.NodeID
LEFT OUTER JOIN WebCommunityStrings ON WebCommunityStrings.CommunityString = NodesData.Community
 WHERE Interfaces.Status = 2 AND Interfaces.Severity > 0 AND InterfaceName = 'Tunnel201' ORDER BY NodesData.Caption, Interfaces.InterfaceIndex DESC
"""
results = swis.query(query)

for row in results['results']:
    #print("{NodeID:<5}: {DisplayName}".format(**row))
    print("{NodeID:<5}: {DisplayName}".format(**row))

输出：

注意：删除了一些更私密的信息，例如服务器名称、密码等

看起来它在抱怨查询中的NOLOCK。我不是SQL专家，但在谷歌搜索之后，它似乎只在微软的SQL Server中使用。我不确定您连接的是哪个数据库，它是由您使用的Python库处理的，但我猜它不是SQL Server。@RobinZigmond id假设NOLOCK不在我的库中-现在去谷歌看看是否有其他使用同一个库的人遇到过这个问题。您在Orion SWQL studio上尝试过您的查询吗？
