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 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 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.

I am trying to read and write database tables that have a date field in them. I am constructing a data.frame, then using dbWriteTable to create the table and dbReadTable to read it. >datatbl<-data.frame( dates, trialnum, fooddel, ethdel, trialtime, trialtype, deliveries, food, ethanol, fcumrec, dcumrec, rrf, rrd) >ifelse(startdate==filelist,

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

I have a table (contact) with several fields and it's PK is an auto increment field. I'm bulk loading data to this table from files which if successful will be about 3.5million rows (approx 16000 rows per file). However, I have a linking table (an_contact) to resolve a m:m relationship between the an and contact tables. How can I retrieve the PK's for the data bulk loaded into

Hi, I'm using R 1.9.0 with RMySQL 0.5-4 and MySQL 3.23.55 on a suse 8.2 box. I have a simulation study and (as usual for newbies in simulation, I guess) I have a lot of data that I want to store in MySQL. I want to write an R script that reads data from RData files and writes it to a MySQL database. I read some R documents (R Data Import/Export and DSC papers) but I'm finding

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

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 <-

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,

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.

Dear list, I'm working with a MySQL-Table and would like to extract selected ids that are stored in a vector: Ids <- c(1,2,3) How do I insert this variable in a for loop like this: For (a in values) { Temp <- dbGetQuery(con, "select * from db Where id = <ID>";) } My problem is to split the select-statement and insert the current id. How can I handle this problem?

I have a data.frame obj with 5 columns whose colnames match the fields in my "contact" table. The only other field my MySQL table has is an id field which is the PK and is set to auto increment.

Using the package /RMySQL/ I have established a connection ('con1') to a MySQL-Database called 'mc'. This database contains a table called 'mc_2000' which has 200000 observations on several variables. One of these variables is called 'B5' (type 'double'). When I generate a numeric vector in R called 'B6' that has the same length as 'B5': How
