整合 Python 連接器 NumPy

以下是與 Python 連接器集成的一個例子 NumPy。

>>>  import numpy
#Connect to the cluster
>>> import redshift_connector
>>> conn = redshift_connector.connect(
     host='examplecluster.abc123xyz789.us-west-1.redshift.amazonaws.com',
     port=5439,
     database='dev',
     user='awsuser',
     password='my_password'
  )
  
# Create a Cursor object
>>> cursor = conn.cursor()

# Query and receive result set            
cursor.execute("select * from book")

result: numpy.ndarray = cursor.fetch_numpy_array()
print(result)

結果如下。

[['One Hundred Years of Solitude' 'Gabriel García Márquez']
['A Brief History of Time' 'Stephen Hawking']]
