Hi All, There's a function called setSqlTypeInfo(driver,value) in RODBC package http://cran.r-project.org/web/packages/RODBC/index.html Description Specify or retrieve a mapping of R types to DBMS datatypes. >From the package(RODBC) TypeInfo.r: setSqlTypeInfo <- function(driver, value) { if(!is.character(driver) || length(driver) != 1L) stop("argument

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

Buen dia Javier, muchas gracias por tu ayuda y el script compartido. Me va a servir como ayuda para seguir aprendiendo sobre RODBC pero no encuentro una solucion para este problema puntual de poder definir el tipo y ancho de las variables, q segun creo se hace con el argumento varTypes. Si alguien tien algun ejemplo donde haya usado la SqlSave y VarTypes, me sera de gran ayuda. Abrazo a todos

Hola Javier, si no estoy entendiendo mal, lo q deseo hacer no se trata de configurar los parametros SQL, sino solo de colocar un vector en el argumento VarTypes de la funcion sqlSave. El manual especifica esa opcion, pero no da ningun ejemplo de como usarla. *varTypes an optional named character vector giving the DBMSs datatypes to be used for* *some (or all) of the columns if a table is to be

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()

Hi, i get error after using a data.frame with subset for "sqlSave". What can i do ? It seems that lines like this in a data.frame structure are after subset deleted and cause the error ? - attr(*, "variable.labels")= Named chr "CUSID" "Welle" "Arbeitgeberfavorit1" "Aktuelle Bewerbungssituation" ... ..- attr(*, "names")=

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I believe, uses the Microsoft Excel Driver DSN). Then I try and save a new table to the database(spreadsheet) using SqlSave, but obtain an error message. Below is

Dear list, Being new to both the postgres database, ODBC and the RODBC interface, I am somewhat confused by some of the problems I am experiencing trying to connect R to the database.

Hi. I attempted to use RODBC and decided to execute all the tests provided in "Test.r" under the unpacked package RODBC folder. Beginning with the following: library(RODBC) library(MASS) USArrests[1,2] <- NA hills <- hills[1:15,] row.names(hills)[12] <- "Dollar ('$')" set.seed(1) # MySQL ## testdb3 is ODBC/Connector 3.51.x, testdb5 is 5.1.x channel <-

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

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

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

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' /

Hello I am trying to move data between R and other systems (e.g. SAS and MS SQL Server) using RODBC.

I'm trying to insert rows of a data.frame into a database table, or update where the key fields of a record already exist in the table. I've come up with a possible solution below, but would like to hear if anyone has a better solution. # The problem demonstrated: # Create a data.frame with test values library(RODBC) tbl <- data.frame( key1 = rep(1:3, each = 2), key2 =

Hi All, I am pretty new for RODBC. I want to save my table to a DB, so I used something like sqlSave(db, a, 'Forecast_Result', rownames = FALSE); But I got an error Error in sqlSave(db, a, "Forecast_Result", rownames = FALSE) : table 'Forecast_Result' already exists Yes, that table has been created before. But I need to overwrite the content in that
