Hello, I am using Oracle 10.2 and R 2.6 on Windows XP. I found RODBC working generally OK (with some minor problems) but very slow, so I am trying to use RJDBC. While getting things (dbGetQuery) works fine, I have problems with saving: dbWriteTable(conn, "WAV", save_df, overwrite = F, append = T, row.names=F) will fail with execute JDBC update query failed in dbSendUpdate (ORA-01000: maximum open cursors exceeded Now, I do not believe that my limit of 300 open cursors has been exceeded - it is only me who uses this Oracle instance and anyway RODBC works (although slowly). The data frame has a few columns and around two thousand rows. Table WAV is automatically created, but remains empty. I would be grateful if someone could help me, Slawek Sick of deleting your inbox?
