Thanks to those who responded to my post about reading SQL server tables using RODBC. Someone in our IT department sent me a link that contained the following information: SQL ODBC connection strings Standard Security:< br> "Driver={SQLServer};Server=Your_Server_Name;DatabaseYour_Database_Name;Uid=Your_Username;Pwd=Your_Password;" Trusted connection:< br> "Driver={SQLServer};Server=Your_Server_Name;Database=Your_Database_Name; Trusted_Connection=yes;" This turned out to have all the infomation I needed. My code wound up looking like: channel <- odbcDriverConnect( "Driver=SQL Server; Server=FRED; Database=StudyXYZ; Uid=my_id; Pwd=my_password;") I used sqlTables(channel) to see what tables were available and a whole bunch of things popped up. So it seems to be working correctly now. Thanks, Paul __________________________________________________________________ [[elided Yahoo spam]] avourite sites.
