dbReconnect {Rdbi} | R Documentation |
dbReconnect
a generic function that, when called with a valid
connection object, reopens the connection to the database backend.
dbReconnect(conn)
conn |
A database connection object. |
A database connection object contains the necessary information to re-establish a connection. Thus, a database connection object can be saved across R sessions and reconnected later. If I can convince the R developers to add a generic function that is always called when objects are restored, then it will be possible to have connections persist across R sessions.
Note that packages that implement the Rdbi interface do not need to
provide a dbReconnect
function as long as the connection object
returned by dbConnect
inherits from "Rdbi.conn" and has
attributes described in the documentation for dbConnect
.
dbReconnect.Rdbi.conn
can reconnect the object. If
dbReconnect.Rdbi.conn
is not general enough, the
package can provide its own method.
