使用 ODBC ZEFE90A8E604A7C840E88D03D6D 连接到 R 中的 SQL 服务器

Question

I'm trying to connect through Rstudio standard ODBC package with driver "ODBC Driver 13 for SQL Server" to a remote SQL Server running on non-default port, but I always get a timeout. 凭据是正确的，因为我可以通过不同的客户端进行连接。

以下指南https://support.rstudio.com/hc/en-us/articles/214510788-Setting-up-R-to-connect-to-SQL-Server-

library(odbc)
con <- dbConnect(odbc(),
                 Driver = "ODBC Driver 13 for SQL Server",
                 Server = "mysqlhost",
                 Database = "mydbname",
                 UID = "myuser",
                 PWD = rstudioapi::askForPassword("Database password")
                 Port = 21433)

不幸的是，package 文档都没有处理连接到非默认端口并且仅更改端口参数不起作用。

Answer 1

连接到非默认端口时，您需要在Port参数中添加正确的端口号，但也需要在Server中以逗号分隔

library(odbc)
con <- dbConnect(odbc(),
                 Driver = "ODBC Driver 13 for SQL Server",
                 Server = "mysqlhost,21433"
                 Database = "mydbname",
                 UID = "myuser",
                 PWD = rstudioapi::askForPassword("Database password")
                 Port = 21433)

这允许您连接到服务器。
