你好
我正在尝试在我的云平台子帐户中连接数据库。 我正在尝试使用pyhdb和eclipse通过python连接。 无法连接到数据库。 在python代码中是
连接= pyhdb.connect( host =" us2.hana.ondemand.com", 端口= 30115, user =" I86 ****", 密码=" * as ** o ** d" ) cursor = connection.cursor()
错误:
" TimeoutError:[WinError 10060]连接尝试失败,因为一段时间后连接方未正确响应,或者由于连接的主机未能响应而建立连接失败"
在Eclipse
错误:
