我正在使用MobaExterm运行我的python脚本。脚本正在从3个表中获取记录。我可以在MySQL工作台中看到我的查询的输出,但是当相同的查询在我的脚本中运行时,我得到了输出,因为“杀死”了
原因是什么。我的问题似乎是对的。
select tsp.data_ip, tsp.IP, tvp.vm_d_ip, tvp.IP FROM cmdb.t_server tsp,cmdb.t_vm tvp,t_ip ip where tvp.SERIALNUMBER= 'AD123' or tsp.SERIALNUMBER= 'AD123' and (ip.ip=tsp.
我是Python的新手。有人能告诉我该如何解决这个错误吗?

我有一个包含2列的表"SomeTableName“:
1) WholeString
2) TSP
在"WholeString“列中,我可以得到两种类型的字符串:
1)
2) TSP_2974_CTV_18933_HotGamesOnYourMobile
我必须创建触发器来填充"WholeString“中的"TSP”列
"2974“-是我必须放在TSP列中的值。
我的尝试:

我是python的初学者,我正在尝试运行python程序,所以我有以下代码:
import networkx as nx

我不得不尝试使用具有3个节点的qiskit的示例,并在名为simulator_statevector.Can Traveling Salesman Problem的IBM后端执行它,然后正常地获得结果。 但是,当尝试解决超过3个节点的TSP问题时,我将n=3改为n= 4。 # Generating a graph of 3 nodes
n = 4
num_qubits = n ** 2
ins = tsp.random_tsp(n, seed=123)
print('distance\n', ins.w)
# Draw the graph
G = nx.Graph()
G.
请告诉我想到的任何事情。然而,我最感兴趣的是如何使我的代码更加地道(现代) C++。
