These methods are deprecated, please consult the documentation of the individual backends for the construction of driver instances.
dbDriver() is a helper method used to create an new driver object
given the name of a database or the corresponding R package. It works
through convention: all DBI-extending packages should provide an exported
object with the same name as the package. dbDriver() just looks for
this object in the right places: if you know what database you are connecting
to, you should call the function directly.
dbUnloadDriver() is not implemented for modern backends.
# S4 method for DatabaseConnectorDriver
dbUnloadDriver(drv, ...)Arguments
- drv
an object that inherits from
DBIDriveras created bydbDriver.- ...
any other arguments are passed to the driver
drvName.
Value
In the case of dbDriver, an driver object whose class extends
DBIDriver. This object may be used to create connections to the
actual DBMS engine.
In the case of dbUnloadDriver, a logical indicating whether the
operation succeeded or not.
Details
The client part of the database communication is
initialized (typically dynamically loading C code, etc.) but note that
connecting to the database engine itself needs to be done through calls to
dbConnect.
