Dear Rusers, I am trying to feed my database with data from a file. But since my file (2010101000.txt) there`s no headers I am facing problem because the result data.frame is not separated my columns. How could I set variables names for each columns in *dbWriteTable*? I have tried the command below but I don`t know how to fill the *field.type*option. dbWriteTable(con, "b20101010",

Hello, I am trying to insert data in a data.frame into a database table using the RMySQL package m <- dbDriver("MySQL") con <- dbConnect(m, host = "blah", user = "blah", password = "blah", dbname = "blah") proid <- dbGetQuery(con, "select max(processed_data_id)+1 from processed_data") spot <-

I had a collection of .bat files running R scripts on my computer that were working perfectly. I then reformatted my computer and now I can't get them working again. I have spent many days scouring the internet but have not found a solution to my problem. I created a simple piece of code named 'test 1.0.R' to try to find the source of my problem. It contains the following -

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37. I've read many postings about this but have not found a mention of my particular problem (some closely related). I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

Hi, The problem was the row.names that were sent to the database and created an primary key duplicate. Now it works fine. BTW congratulations for the package. It copied 15300 rows by 11 columns in less than 5 seconds, in my PIII 833 with 1 GB RAM. > system.time(dbWriteTable(con, "TBL_SIMDATA", TBL.SIMDATA, append = TRUE, row.names=F)) [1] 3.87 0.05 4.86 0.01 0.00 Just one

I am using R 2.8 and the latest versions of RMySQL on a Windows XP 64 bit machine. I was wondering if someone could help me figure out how to use dbWriteTable without inserting \r into my table. Consider the following code snippet, which is run after I connect to my database. myDFOut = dbReadTable(conn, "myDF") print(myDFOut) myDFIn = data.frame(x=paste("x", 1:5, sep =

I have been having trouble getting RMySQL to work on Mac OS 10.4. It was working fine for me about a year ago but I didn't touch it for a while and several upgrades of R, MySQL, and OS X later, it is not working. I first had the problem that others have been having getting the error discussed in https://stat.ethz.ch/pipermail/r-sig-mac/2005- November/002435.html saying that

List, Last week with the help of Uwe and some other folks I was able to get RMySQL 0.5-7 compiled against R 2.4.1 and MySQL 5.0.27. It was working fine--I was able to send select queries to the db, put the results in a data frame, and so forth. Today, dbDriver() threw an error: > dbDriver(MySQL) Error in function (classes, fdef, mtable) : unable to find an inherited method for

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

Hi, useR- In RMySQL, how do I overwrite records? (equivalent to "replace" query). For example, suppose that dat2 is a newer data.frame than dat1. con <- dbConnect(MySQL()) res <- dbWriteTable(con, "DBname", dat1, row.names=F, append=T, replace=T) res <- dbWriteTable(con, "DBname", dat2, row.names=F, append=T, replace=T) This would not update/replace the

I am feeling rather dumb right now. I created what I thought was a data.frame as follows: aaa <- lapply(split(moreinfo,list(moreinfo$m_id),drop = TRUE), fun_m_id) m_id_default_res <- do.call(rbind, aaa) print("==========================================") m_id_default_res print("==========================================") ndf <- m_id_default_res[, c('mid',

I am a newbie in R and want to use MySQL database. Here is what I have and done. R 1.8.0 mysql 4.0.16 Both running in Windows XP. I download the RMySQL.zip from the internet and used the Packages installer in the RGui to install RMySQL. I also installed DBI packages. I ran the following and got the error. > mgr<-dbDriver("MySQL") Error in dbDriver("MySQL") :

Since there doesn't appear to be an RMySQL rpm for SuSE 8.*, does anyone know if the 7.3 version will work with the SuSE 8.2 rpms of R and DBI? The package installs without complaint, but when I try to run con <- dbConnect(dbDriver("MySQL"),dbname="test") I get the error Error in dbConnect(dbDriver("MySQL")) : couldn't find function

Hi All, I've finally gotten around to database access using R. I'm happily extracting rows from a MySQL database using RMySQL, but am having problems appending rows to an existing table. What I *want* to do is to append rows to the table, allowing the database to automatically generate primary key values. I've only managed to add rows by using dbWriteTable( con,

Dear r helpers, At first, I apologize for raising a query which seems to be a stupid interpretation on my part. I am trying to learn SQLite. Following is an example given in the RSQLite.zip file (Page # 4) drv <- dbDriver("SQLite") tfile <- tempfile() con <- dbConnect(drv, dbname = tfile) data(USArrests) dbWriteTable(con, "arrests", USArrests) On the similar

Creating a temp table isn't completely intuitive with MySQL 5 and R 2.8..1, but it can be done. > library(RMySQL) Loading required package: DBI > con <- dbConnect(dbDriver("MySQL"), dbname = "foo", user="me",password="secret") > x<- data.frame(1:10) > colnames(x) <-c("x") > dbWriteTable(con, "#x", x,

Hi, I have a question reading using RMySQL trying to load one R vector into a table column. To be more specifically, the table is there populated. Now I add a new column and want to populate this. Can some colleagues on this list teach me how to do this? I know how to write one R object/table into MYSQL table using dbWriteTable. But in this situation, I just want to do one column. Thanks

Hi Consider the following code > x <- rep(1:13, 13) > y <- 1:3 I want to select all elements in x which are equal to 1, 2 or 3. I know that I could use > sel <- x==y[1] | x==y[2] | x==y[3] > x[sel] to obtain the values, but in my analysis, the y-vector is thousands of elements long. Is there any way, that I can do that easily? Thanks Rainer -- Rainer M. Krug, Dipl.
