RODBC Oracle and VB automation with R(D)COM
...n see that the value is -1, which occurs when a connection fails: >channel<-dget("c:/channel.Rdata") >channel [1] -1 I have identified the problem to the a piece of code trying to establish the connection (residing in the odbcConnect function): odbcDriverConnect(st, case = case, believeNRows = believeNRows) Where st has the value "DSN=MY_DB;UID=MYUID;PWD=MYPWD", and this I believe is the case in both instances since I tried to replicate the odbcConnect code manually in VB, and the two connection strings checked out. It seems to boil down to the following code in odbcDriver...

ODBC Oracle access
...d through to the oracle database in question and that seems to work OK but it would be preferable to cut out the MS access middle-man. The command I'm attempting to use is: conn<- odbcConnect(dsn='myDSN', uid = "myUID", pwd = "myPWD", case = "oracle",believeNRows=FALSE) I wouldn't be surprised if there is an issue with the dsn configuration and not R (though I cant find it) so any tips as to things that I should check there would also be gratefully received.
