Hello, I am not able to query Sybase IQ database from R using RODBC package. Check the below code R> sybaseiq.query <- function (sql, ..., as.is = FALSE) { connstr <- "Driver={Sybase IQ};UID=ajadhav2;PWD=*****;ServerName=PSGSESHR01A_IQ;CommLinks=SharedMemory,TCPIP{host=psgseshr01_iq.sg.csfb.com;port=3051}" chan <- odbcDriverConnect(connstr)

Dear list, RODBC is mostly working very well on Windows XP talking to MS SQL Server. However, when trying to retrieve a result set in repeated batches the first batch returns results ok, but then subsequent calls return no data (see code below). I tried setting believeNRows=FALSE both in odbcConnect() and in sqlGetResults() but this doesn't appear to make any difference. Also odbcFetchRows()

Dear Sir/Madam, I am desperately in need of some help. I am trying to access tables from the oracle database and inserting them into R via a data frame and I keep getting an error saying that "Error in .Call(C_RODBCFetchRows, attr(channel, "handle_ptr"), max, buffsize, : negative length vectors are not allowed". My connection is fine and my code for this is:

I got a table on SQL Server, which has columns EquationId (int) and Formula (varch(900)). I need to select Formula with certain EquationId, for example, Select Formula from OGA_DEV.dbo.Equation where EquationId = 3 I tried to work within RGui using RODBC: > library(RODBC) > conn = odbcConnect("SQL Server") > odbcQuery(conn, "Select Formula from OGA_DEV.dbo.Equation where

Dear R-SIG-Debian, while trying to query data from an SQLite database through RODBC on Debian testing, R crashes with the following message: library(RODBC) con3 <- odbcConnect("test3") # 'test3' being an ODBC datasource configured with SQLite3 driver, # but the same happens with SQLite driver sqlQuery(con3, "select * from test") # 'test' being any table

Hi WizaRds, I'm experiencing a problem connecting to an Oracle 10g database via RODBC (I'm getting this on Microsoft XP). The same SQL queries via PL/SQL Developer work just fine, but when I pump the query through sqlQuery in RODBC then I get a data frame back with 0 rows. I cut the query down alternating between PL/SQL and RODBC until I figured that it's some kind of row limit or

1. Can I avoid having RODBC use so much memory (35 times the data size or more) making a data.frame & then .rda file via. sqlQuery/save? 2. If not, is there some more appropriate way from w/in R to pull large data sets (2-5GB) into .rda files from sql? [R] reducing RODBC odbcQuery memory use?

I have an MS Access database with one table and one column holding rep(1:10) I use: library(RODBC) channel <- odbcConnect("test") sqlQuery(channel, paste("SELECT col FROM tblTest"), believeNRows=FALSE) and get: 49 50 51 52 53 54 55 56 57 12337 What?

Dear R Gurus, I would very much appreciate some help with this code snippit from my RODBC package. R crashes or exhibits bizarre behaviour when repeatedly fetching large numbers of rows.

Hello, I am new to the RODBC package, but I have looked over the PDF as well as a few websites that go over the SQL language. I can connect to my database fine using >channel<-odbcConnect("Oracle ODBC") # then am prompted to enter my user id and password After that I'd like to use the odbcQuery function and the SQL statement: SELECT * FROM table_name WHERE SAMPLE_YEA LIKE

Hi, Does anyone know how to pass dynamic sql statement to RODBC function "odbcQuery()" or "sqlQuery()"? eg.: under R session, I did: >library(RODBC) >channel<-odbcConnect(...) >data1<-2.5 >data2<-5.0 I want to construct the INSERT sql statement using variables "data1" and "data2" and pass this statement to odbcQuery() . Can I do this?
