Dear List, Java Exception error while reading large data in R from DB using RJDBC. I am trying to read large data from DB table(Vectorwise), using RJDBC connection. I have tested the connection with small size data and was able to fetch DB tables using same connection(conn as in my code).
Please suggest where am i going wrong or alternate option to solve such issues while reading large DB table. drv <- JDBC(paste(db_driver, sep = ""), paste(db_jar_file, sep = ""), identifier.quote="`") conn <<- dbConnect(drv, paste(db_server, sep = ""), paste(db_server_lgn, sep = ""), paste(db_server_pwd, sep = "")) s <- sprintf("select * from cypress_modeldev_account_info") temp <- dbGetQuery(conn, s) Error in .jcheck() : Java Exception <no description because toString() failed>.jcall(rp, "I", "fetch", stride)<S4 object of class "jobjRef"> -- View this message in context: http://r.789695.n4.nabble.com/Java-Exception-error-while-reading-large-data-in-R-from-DB-using-RJDBC-tp4647844.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
