Since can generate a tbl() directly from a DBI connection we no longer recommend using src_dbi().
src_dbi(con, auto_disconnect =FALSE)
Arguments
con: An object that inherits from DBI::DBIConnection , typically generated by DBI::dbConnect
auto_disconnect: Should the connection be automatically closed when the src is deleted? Set to TRUE if you initialize the connection the call to src_dbi(). Pass NA to auto-disconnect but print a message when this happens.
