如何解决：RODBC错误：状态08001，代码0，

问题描述

这是我的连接字符串

library(RODBC)

odbconnection <- 
  odbcDriverConnect("Driver=SQLServer;Server=some_address; Database=some_db;Uid=some_username; Pwd=some_password")

它返回：

Warning messages:
1: In odbcDriverConnect("Driver=SQLServer;Server=some_address; Database=some_db;Uid=some_username; Pwd=some_password") :
  [RODBC] ERROR: state 08001,code 0,message [RStudio][SqlServer] Problem establishing connection to the server.
2: In odbcDriverConnect("Driver=SQLServer;Server=some_address; Database=some_db;Uid=some_username; Pwd=some_password") :
  ODBC connection failed

如何解决此错误：[RODBC] ERROR: state 08001,？

解决方法

尝试使用DBI软件包和host:port/service_name之类的

library(DBI)
con <- dbConnect(drv,'user','pass','some_address:someport/some_db')
dbGetQuery(con,"select count(*) from some_db")
