The first non-maintenance update of RODBC since January 2003 is now on CRAN and will soon propagate to mirrors. From the ChangeLog: * Select the decimal point from Sys.localeconv. * Add an external reference and finalizer so open channels get closed at the end of the session or when there is no R object referring to them. * There is no longer a

Hello, We are having some strange issues with RODBC related to integer columns. Whenever we do a sql query the data in a integer column is 150 actual data points then 150 0's then 150 actual data points then 150 0's. However, our database actually has numbers where the 0's are filled in. Furthermore, other datatypes do not have this problem: double and varchar are correct and do not

R 2.8.1 Ubuntu 64amd RODBC 1.2-5 --------------------------------- This was a hard-to-track bug for me, because sqlQuery() did not fail - instead, it looked like it returned some good data and some NA where there should have been numbers and 0 where there should have been NAs. I did: (a) sqlQuery( o, qry, as.is=TRUE, errors=TRUE, rows_at_time=1024 ); (b) sqlQuery( o, qry, as.is=TRUE,

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

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 all, I am encountering an RODBC problem in R 2.15.1 in windows 64 bit which I do not encountered in the same set up in windows 32 bit (the latest binary version of RODBC in both cases from the same depository gotten by install.packages(‘RODBC’), Oracle ODBC client software installed in 64 and 32 bit respectively) 1. The code looks like library(RODBC) credentials <-

I'm trying to load Affy Annotation data from an Access database into R using RODBC. This has worked fine for quite some time. The bug seems to be correlated to RODBC versions 1.1-7 and later. Works fine: R 2.2.0 with RODBC 1.1-4; R 2.3.0 or R 2.4.1 with RODBC 1.1-6 Fails: R 2.3.1 with RDOBC 1.1-7; R 2.4.1 with RODC 1.1-7 or 1.1-8 Details ===== This works fine: Version 2.2.0

I've noticed that RODBC seems to be an order of magnitude slower in retrieving rows from a table than ODBC (or JDBC) access in other tools. I'm wondering why that is, and whether there are things I can do to improve performance beyond what I've tried. I've checked the documentation, and have tried the rows_at_time= and buffsize= options, which helped a little, but it is still

I am trying to connect to an internal database and use the sqlQuery command to reduce and retrieve data using the following code: channel <-odbcConnect("some_dsn", uid="", pwd="") txt<-'SELECT Date, Region, Price FROM TableXYZ WHERE Type="Domestic"' sqlQuery(channel, cat(txt,"\n"),errors=TRUE,) close(channel) However, I get the

I have been using RODBC to connect to an Access database to capture data to create plots. Recently I found incomplete charts. Upon investigation I discovered that the data retrieved stopped at 3276 rows (records) out of a table with over 5600 records. I've tried changing "max","buffsize", and "rows_at_time" but it still returns only 3276 rows. Is this a

What is the recommended way of checking whether an RODBC connection is open? Since odbcValidChannel is not exported from namespace RODBC, I suppose I shouldn't be using it. This is the best I could come up with, but it seems a bit 'dirty' to be using a tryCatch for something like this: odbcOpenp <- function(conn) tryCatch({odbcGetInfo(conn);TRUE},error=function(...)FALSE)

Hi, I'm using R-2.8.1 for windows. I wrote a script calls the RODBC package to run sql queries against an oracle database. It runs fine when run from the rconsole and returns a data.frame with a summary for a set of experiments. I want to run this script using the rinterface.RunRFile command in an excel plugin, using the rexcel package. When I run the code from my excel plugin I

I am running R version 2.8.1 on Windows XP OS. This works fine. (Data.frame dta is created with records from the DB2 table.): sql <- "select * from storage.testappend_slt order by uut" dta <- sqlQuery(channel,sql) But when I try to append records (from data.frame newdta) to the same DB2 table. I get an error: sqlSave(channel, newdta, tablename = storage.testappend_slt, append

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? The above should, of course, read: 1 2 3 4 5 6 7 8 9 10 I tried the 'odbcQuery' /

What is this error message about and how do I troubleshoot it? > sqlTables(channel) Error in .Call("RODBCFetchRows", attr(channel, "handle_ptr"), max, buffsize, : negative length vectors are not allowed The channel was created as such channel <- odbcConnect("Labdata") I think this is telling me that my odbcConnect command worked >

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 All, I have the following problem when reading files (a lot of them) in the spreadsheetML format into R. The spreadsheetML format is an xml format to allow easy import of multisheet data in Excel. As far as I can see, a direct import into R (using the XML package) is not feasible. I use the software ssconvert (included in Gnumeric) and call it from R. It converts the spreadsheetML into xls

Hi, I'm able to establish a successful odbc connection using RODBC 1.3-2 on Win 7 and R 2.12.0. But I'm getting the following error message when I try to save a data frame into the debase as shown below. library(RODBC) bbdb <- odbcConnect("bbdb") odbcGetInfo(bbdb) # returns ok sqlSave(bbdb, USArrests, rownames = "state", addPK=TRUE) # example from the RODBC manual

Dear R users, I am trying to connect R to data that is in a Access Database but I have problem with the construction of queries using special characters. I am using RODBC package. The following is working : > MyQuery<-paste("SELECT first( (DateHeure) ) , avg(NNO3_AT322_OUT_moy) AS Cond FROM Colonne_3 ") > Col3<-sqlQuery(con, query=MyQuery) > Col3
