R RODBC SQL Server Connection - sql-server

Question

I use windows authentication to connect to sql server. And I'm trying to connect to the sql server table in R. But R is not connecting to the database. I also tried typing in my windows login for uid and pwd. still no luck.
library(RODBC)
driver.name <- "SQL Server"
db.name <- "dw-xxx"
host.name <- "xx-xxx"
port <-"xxxx"
server.name <-"dw-xx"
con.text <- paste("DRIVER=",driver.name,
";Database=",db.name,
";Server=",server.name,
";Port=",port,
";PROTOCOL=TCPIP",
";trusted_connection=true",
sep="")
con1 <- odbcDriverConnect(con.text)
Warning messages:
1: In odbcDriverConnect(con.text) :
[RODBC] ERROR: state 42000, code 4060, message [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "dw-xxx" requested by the login. The login failed.
2: In odbcDriverConnect(con.text) :
[RODBC] ERROR: state 01S00, code 0, message [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute
3: In odbcDriverConnect(con.text) : ODBC connection failed

Answer 1

I got this same problem. Apparantly the PORT format was not accepted. It was working when I moved the port to the server part likes this (giving SERVER=server,port):
con.text <- paste("DRIVER={",driver.name,"}",
";Database=",db.name,
";Server=",server.name,
",",port
";PROTOCOL=TCPIP",
";trusted_connection=true",
sep="")
