Question

我使用的是ubuntu和python3.5 尝试使用凭据（演示）连接远程数据库

jdbc_host = '57.56.254.98'
jdbc_port = '21433'
jdbc_user = 'username'
jdbc_pass = "password"
jdbc_dbname = 'database'
jdbc_server=jdbc_host+':'+jdbc_port
jdbc_url = 'jdbc:sqlserver://{0}:{1}'.format(jdbc_host, jdbc_port,jdbc_dbname)
jdbc_driver_path = 'sqljdbc41.jar'
configProperties = {
    'user':jdbc_user,
    'password':jdbc_pass
}

我用以下代码尝试了pyodbc，pymssql和pypyodbc

con = pyodbc.connect("DRIVER={SQL Server};server=jdbc_server;database=jdbc_dbname;uid=jdbc_user,pwd=jdpc_pass")

和我从许多网站发现的类似代码示例都返回了一些错误，如

Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found (0) (SQLDriverConnect)")

我尝试配置FreeTDS服务器，但它返回错误

Authentication failed for user 'username'

虽然我可以使用具有相同凭据的代码将此数据库与pyspark连接

marksInfo = spark.read.jdbc(url=jdbc_url, table='tablename', properties=configProperties)

我可以使用pyspark读取和处理来自它的数据，但是对于'Action'操作中的这个小型数据库，它有点慢，所以寻找备选方案

希望我很清楚感谢任何帮助将不胜感激

我可以使用tsql与数据库连接

tsql -S server:port -U username -P 'p@sword\\'

但pyodbc会抛出此错误

Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'FreeTDS' : file not found (0) (SQLDriverConnect)")
