Database Interface and MySQL Driver for R

Build Status AppVeyor Build Status CRAN_Status_Badge CRAN RStudio mirror downloads Coverage Status

RMySQL is a database interface and MySQL driver for R. This version complies with the database interface definition as implemented in the package DBI 0.2-2.

Hello World

# Connect to my-db as defined in ~/.my.cnf
con <- dbConnect(RMySQL::MySQL(), group = "my-db")

dbWriteTable(con, "mtcars", mtcars)

dbListFields(con, "mtcars")
dbReadTable(con, "mtcars")

# You can fetch all results:
res <- dbSendQuery(con, "SELECT * FROM mtcars WHERE cyl = 4")

# Or a chunk at a time
res <- dbSendQuery(con, "SELECT * FROM mtcars WHERE cyl = 4")
  chunk <- dbFetch(res, n = 5)
# Clear the result

# Disconnect from the database


Binary packages for OS-X or Windows can be installed directly from CRAN:


The development version from github:

# install.packages("devtools")

Installation from source on Linux or OSX requires MariaDB Connector/C. On some older platforms you can also link against Oracle's libmysqlclient driver but the mariadb implementation is much better.

On recent Debian or Ubuntu install libmariadb-client-lgpl-dev. In Ubuntu 14.04 this was called libmariadbclient-dev.

sudo apt-get install -y libmariadb-client-lgpl-dev

On Fedora, CentOS or RHEL we need mariadb-devel:

sudo yum install mariadb-devel

On __OS-X__ use [mariadb-connector-c]( from Homebrew:

brew install mariadb-connector-c

## MySQL configuration file

Instead of specifying a username and password in calls to `dbConnect()`, it's better to set up a MySQL configuration file that names the databases that you connect to most commonly. This file should live in `~/.my.cnf` and look like:

[database_name] option1=value1 option2=value2

If you want to run the examples, you'll need to set the proper options in the `[rs-dbi]` group of any MySQL option file, such as /etc/my.cnf or the .my.cnf file in your home directory. For a default single user install of MySQL, the following code should work:

[rs-dbi] database=test user=root password= ```
