我运行from matplotlib import style
import numpy as np
import datetime as dt
from datetime import datetime
style.use('ggplot')
data = np.genfromtxt('output2.csv', delimiter=',', names=True)
x = data['Time']
y = data['CH_1']
fig = plt.figure()
fig.add_subplot(111)
plt.plot(y)
plt.show()
...我收到以下错误：
OperationalError ：（“ 08S01”，“ [08S01] [Microsoft] [ODBC SQL Server驱动程序]通信链接失败（0）（SQLExecDirectW）”）
但是，当我运行import pyodbc
#odbc
conn = pyodbc.connect('Driver={SQL Server};'
'Server=PMOV319\LINE;'
'Database=Warehouse;'
'Trusted_Connection=yes;')
cursor = conn.cursor()
cursor.execute('SELECT [StreetAddressLine1],[City],[ZipCode] FROM Dim.Bet')
#cursor.execute('SELECT * FROM Dim.Bet')
for row in cursor:
print((row))
时，我得到了所有输出。我该如何解决这个问题？
