Joining R Local Dataset with Table from Database
You'll either need to do it in R or Oracle (I'm not sure you can do it directly across the ODBC boundary) -- I'd actually think Oracle would be more performant for this sort of thing. But anyways, import your data from Oracle into R as a data.frame and then look at the ?merge command. Best, Michael

Hi All,
I want to join a table (Dataset) that is created in R with a table that is
in oracle database. Can some one help me in accomplishing this task in R?
Example Code:
library(RODBC)
DB_CONNECT <- odbcConnect("DSN_NAME")
TABLE_JOIN <- sqlQuery(DB_CONNECT, "SELECT * FROM DB_TABLE WHERE COL_1 NOT
IN (SELECT COL_1 FROM DATA_SET_R) ")
Regards,
Madana
