Armstrong, Whit wrote: Thanks, everyone. I'll give freeTDS a try. One final hitch to be aware of when using FreeTDS: MS SQL Server authenticates db connections in two different ways (well actually three, but it's just the combination of 1 and 2): 1) Sql server authenticates the connection, meaning you must have an SQL server account. FreeTDS will handle this fine. 2) the SQL server OS authenticates the connection with an NT Domain login. That's the domain\username you use to login to your Windows machine. FreeTDS will ONLY handle this over TCP/IP, not over DCE/RPC, so be aware.

[R] RODBC on linux
I am using RODBC 1.1-2 with R 2.0.0 on a Debian box with a singel Pentium processor. My database is Informix 7.32. When I run a sql query I get the table header back but no data is selected. Please note this example: Table t1 has two columns, a and b. The table is populated with three rows. Thi si the definition of the table: Column name TypeNulls a smallintyes b integer yes sqlQuery(pricedb, select * from t1) [1] a b 0 rows (or 0-length row.names) class(a$a) [1] integer class(a$b) [1] integer using my C code on the same box, utalizing teh same odbc installation I get: 12 34 56 Does anyone have an idea why I get the table header but no data?

Re: [R] RODBC on linux
If you look in the RODBC help pages for odbcConnect you will see this mentioned with respect to Oracle and Sybase. Try the fix mentioned there.
