similar to: RODBC & MS SQL Server: repeated calls to sqlGetResults() problem

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' /

I have compiled and linked a 64 bit version of R (R 2.9.2) and the corresponding unix ODBC 64 bit package When issuing a SqlQuery, I get the following error > library(RODBC) > channel <- odbcConnect("OraLSH", <user>, <password>) > sqlQuery(channel,"select sysdate from dual") Error in .Call(C_RODBCFetchRows, attr(channel, "handle_ptr"), max,

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

I am getting segfaults when I try to read a large binary object from a SQL Server database via RODBC. I am using the FreeTDS ODBC driver, and it has been working fine when reading from this same database. I have included relevant parts of the session below. Each row of the v_MAFiles view holds a text, html or pdf version of a document. The FileType entry is one of TXT, PDF, or HTML. If

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

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

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?

Hi Michael, Here is the result of my first testing: (0) Dr. Watson Sorry, I should have given a more precise description: by default in R exists a function with the name 'table', if you use this name as in odbcPrimaryKeys(0, table) a Dr. Watson occurs, because table does not give a table name. However, it is always a good idea to prevent Dr. Watsons, even if it is triggered by a

Hello everyone! I'm having the dreaded repeated rows problem in RODBC. Specifically, when I have a NULL value in a column, odbcFetchRows reads the value not as NULL or NA but as the most recent non-NULL value in the column. If there is no such non-NULL column, odbcFetchRows reads the value as 0. Let me give you an example (though you won't be able to run it with the "product"

Hi, I'm trying to establish a connection to a MySQL database, and am using the rodbc package for it. This is in a GNU/Debian Linux box, with the corresponding Debian unstable packages. I can login to my MySQL databases from any shell and directory, so the problem is probably not there. Here's an example of what I'm doing: R> odbcConnect("test",

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 R-Helpers, I would like to read an Excel .xls file via RODBC. I have successfully run the example in p. 18 of "R Data Import/Export". The problem I am facing is that Excel's ODBC driver seems to have a limit on the number of fields/columns (output below). I haven't found any documentation on what this limit L might be, but I know that 128 <= L < 256. Does anyone know

I run R 2.0.1 on Debian and connect to Informix database via RODBC. In the table below the column "month" is of type char(1). RODBC seems to be converting this column to boolean if the value is F or T. This is the data in my table: id month year 25 F 2005 26 Z 2005 When I select * for id 25 I get 25 FALSE 2005 When I select * for id 16 I get 26 Z

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

I'm currently getting the following error:
