Examples

# NOT RUN {
ora <- dbDriver("Oracle")
## connecting without a connect string
con <- dbConnect(ora, "scott", "tiger")

## connecting with a connection string with SID
host <- "myhost"
port <- 1521
sid <- "mysid"
connect.string <- paste(
  "(DESCRIPTION=",
  "(ADDRESS=(PROTOCOL=tcp)(HOST=", host, ")(PORT=", port, "))",
  "(CONNECT_DATA=(SID=", sid, ")))", sep = "")

## use username/password authentication
con <- dbConnect(drv, username = "scott", password = "tiger",
                 dbname = connect.string)

## connecting with a connection string with service name
