MariaDB()

Arguments

drv

an object of class MariaDBDriver or MariaDBConnection.

dbname

string with the database name or NULL. If not NULL, the connection sets the default database to this value.

username, password

Username and password. If username omitted, defaults to the current user. If password is omitted, only users without a password can log in.

host

string identifying the host machine running the MariaDB server or NULL. If NULL or the string "localhost", a connection to the local host is assumed.

unix.socket

(optional) string of the unix socket or named pipe.

port

(optional) integer of the TCP/IP default port.

client.flag

(optional) integer setting various MariaDB client flags, see Client-flags for details.

groups

string identifying a section in the default.file to use for setting authentication parameters (see MariaDB()).

default.file

string of the filename with MariaDB client options, only relevant if groups is given. The default value depends on the operating system (see references), on Linux and OS X the files ~/.my.cnf and ~/.mylogin.cnf are used.

ssl.key

(optional) string of the filename of the SSL key file to use.

ssl.cert

(optional) string of the filename of the SSL certificate to use.

ssl.ca

(optional) string of the filename of an SSL certificate authority file to use.

ssl.capath

(optional) string of the path to a directory containing the trusted SSL CA certificates in PEM format.

ssl.cipher

(optional) string list of permitted ciphers to use for SSL encryption.

...

Unused, needed for compatibility with generic.

bigint

The R type that 64-bit integer types should be mapped to, default is bit64::integer64, which allows the full range of 64 bit integers.

timeout

Connection timeout, in seconds. Use Inf or a negative value for no timeout.

timezone

(optional) time zone for the connection, the default corresponds to UTC. Set this argument if your server or database is configured with a different time zone than UTC. Set to NULL to automatically determine the server time zone.

timezone_out

The time zone returned to R. The default is to use the value of the timezone argument, "+00:00" is converted to "UTC" If you want to display datetime values in the local timezone, set to Sys.timezone() or "". This setting does not change the time values returned, only their display.

Time zones

MySQL and MariaDB support named time zones, they must be installed on the server. See https://dev.mysql.com/doc/mysql-g11n-excerpt/8.0/en/time-zone-support.html for more details. Without installation, time zone support is restricted to UTC offset, which cannot take into account DST offsets.
