Hello, I would like to call a function that can take infinite time to be executed in some circumstances (which can not be easily detected). So, I would like that once the function is being executed for more than two seconds it is stopped. I have found documentation for timers but i did not found how to "kill" a function. Moreover, I would like not to change the function code (it should

Till yesterday I was more than satisfied by RODBC, specifically by sqlSave which I had been happily using in a daily crontab R batch job regularly updating a postgresql db for as long as one year. In this R- batch I was able to save records into indexed tables *** even though *** they already existed. in this case sqlSave simply neglected those rows of the input table that were offending the

Hello, I contact you after having unsuccessfully asked my question to R mailing list. I use the package RODBC to connect to a MS-SQL server. I am able to getQuery from the database. I am now studying the sqlSave some data into the database. Unfortunetly, I meet some issues relating to the format of the data that arrives into the database. I have three columns. The first one should be in the

Hi, Using the fast=F option, sqlSave saves without matching column names. It looks like a bug to me.......... Here's a simple (artificial) example. ----------------------------------------- Create a dataframe and save it to a database table "test" as follows: df <- data.frame(T=1, S=10) sqlSave(channel, df, "test", rownames=F) The table now looks like T S 1 10 If

Hello, After a (bad) first try some months ago, I'm trying again to use RODBC package instead of DBI+RMySQL packages to populate MySQL database. The main command is sqlSave(channel, data_df, tablename, append=T, rownames=FALSE, colnames=FALSE, fast=FALSE, varTypes=vartypes) where data_df is the data.frame I want to save and vartypes is obtained following the tip given here

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

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

Hi all: I have created a MS Access table named 'PredictedValues' through the statement below: myDB <- odbcConnectAccess("C:/Documents and Settings/Owner/Desktop/Rpond Farming.mdb",uid="admin",pwd="") sqlSave(myDB,PredictedValues,rownames=FALSE) close(myDB) But if I run the code again with new values I get the message below: Error in sqlSave(myDB,

I am using R2.6.0 on “Windows Small Business Server 2003”. I apologize if the answer to my question is available…I have searched but have not found anything that I thought helped me. I have a dataframe that contains ~4.5 million rows and 5 columns. (see memory and df details below). I am trying to save the dataframe to a MS SQL Server database, using the “sqlSave” function. The code

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

Buen dia compañerxs de R, les traigo una pregunta bastante especifica. En el trabajo me estan requiriendo el uso de SQL, asi q estoy aprendiendo a usarlo desde R, con el paquete RODBC. Mi problema puntual es que al crear una tabla en el servidor SQL a partir de un data frame en R (usando la funcion sqlSave) no puedo definir el tipo de variables que quiero usar en el data frame. Segun entiendo

Hi All, con <- member <- class <- list() for(i in 1:5) { con[[i]] <- odbcConnectAccess(paste("C:/Desktop/Data/source",i,".mdb",sep = '')) #read data from Access files member[[i]] <- sqlFetch(con[[i]],'member') #get table data from *.mdb files observe[[i]] <- sqlFetch(con[[i]],'observe') #get table data from *.mdb

Hi, I am having trouble to write/create a table, which has a date field. I want to create a stock price table, which has fields of ticker, date, price. First, I created such a table in Microsoft Access with a few rows inputs. Using sqlQuery, I found that the date field was retrieved as POSIXct value. Then I made a data.frame with POSIXct as the data type for dates. However, I received the

Hey everyone, I don't have a question. Instead some helpful advice with things I've learned from trying to connect 'R' to databases using RODBC. ROBDC is a very handy tool that, once you have everything fixed up nicely, is a great way to have scripts run fairly autonomously, safe in the knowledge that data isn't accidentally messed up. But I was fairly ignorant

Dear R users, I've already asked this question yesterday, but, though I had answer for the other ones (and they helped a lot, thanks), for some reason didn't get an answer for this one (I would also appreciate to know why, so that I can improve the quality and clarity of my future questions). Here it is again: I'm trying to use RODBC to export dataframes to xls files. When I run

Hello, I'm still trying to modify my script in order to use RODBC instead of RMySQL (no more ready-to-use package for windows). My new problem is the following one (not seen with RMySQL): I'd like to copy a data.frame to a mysql table. One column is a numeric one with big integer like : 2005000206110 (13 figures) If I type this number in R, I get: 2.005e+12 and when I use sqlSave to

I am running R version 2.9.2 on Windows XP OS with RODBC version Version: 1.3-0. Has anyone out there in the R user community successfully appended records to a DB2 table on a remote database using the sqlSave function in the RODBC package? (or by any other means from R?) I posed a similar question a few months ago and unfortunately, did not receive a response. I was hoping recent upgrades to

Hi, I am running the RODBC examples form the help guide. I am trying to UPDATE a table in an Access data base but I am having an error. library(RODBC) library(termstrc) path = getwd() setwd(getwd()) dbName = "data.mdb" pathdbname = paste(path,"/",dbName,sep="") accesChannel = odbcConnectAccess(pathdbname, uid = "", pwd = "")

Hi, I am trying to use sqlSave to write a dataframe to an existing table in a DB2 database. The database contains two schemas. My experience is the following: (1) in the case that tablename is left empty in sqlSave, R writes to the instance level schema (2) in the case that a tablename is specified and that table name exists only once in the database, R will write to that table irrespective

I have an existing table, and I am trying to use sqlSave to append additional rows to this database. I omit the primary key, which is a uniqueidentifier type (MS SQL), so that the database can populate that field. However, I get the following error: > sqlSave( ch, result, tablename=thetablename, append=TRUE, rownames=FALSE, colnames=FALSE ) Error in odbcUpdate(channel, query, mydata,
