Question

我正在尝试通过python连接到加密的exasol数据库。它在未加密时连接没有问题。

EXASOL.connect似乎是基于pyodbc，是否有人在使用开启加密的pyodbc时取得了成功？

我尝试将 ENCRYPTION = Y 作为字符串参数传递，基于manual (page 343)但没有成功。

ENCRYPTION打开自动加密功能。有效值为＆＃34; Y＆＃34;和＆＃34; N＆＃34; （默认是＆＃34; N＆＃34;）。

似乎忽略了它。保持爆炸 - 操作错误：数据库错误[08004]连接异常 - 客户端连接必须加密。

database_table = "SCHEMA_NAME.MY_TABLE"
conn = EXASOL.connect('ws://192.168.56.101:8563', 
                      'UID=sys', 
                      'PWD=pwd', 
                      'ENCRYPTION=Y', 
                      )

sql = "SELECT * FROM %s LIMIT 1000;" % database_table
df_sql = pd.read_sql(sql, conn)

OperationalError: database error [08004] Connection exception - Client connection must be encrypted.

Answer 1

PyEXASOL驱动程序支持WebSocket协议和HTTP传输的加密。

您需要做的就是将 encryption = True 传递给连接选项。

Python连接到已打开加密的EXASOL
