Driver Options

Please refer to the official Oracle page for instructions on how to download and setup the driver: Oracle ODBC driver page

Package Options

There are packages that either connect via ODBC but do not provide support for DBI, or offer DBI support but connect via JDBC. The odbc package, in combination with a driver, satisfies both requirements.

Another package that provides both ODBC connectivity and DBI support is ROracle. The current version of dbplyr in CRAN does not yet fully support a connection coming from ROracle, but we are working on it.

Connection Settings

There are five settings needed to make a connection:

  • Driver - See the Drivers section for more setup information
  • Host - A network path to the database server
  • SVC - The name of the schema
  • UID - The user’s network ID or server local account
  • PWD - The account’s password
  • Port - Should be set to 1521
con <- DBI::dbConnect(odbc::odbc(),
                      Driver = "[your driver's name]",
                      Host   = "[your server's path]",
                      SVC    = "[your schema's name]",
                      UID    = rstudioapi::askForPassword("Database user"),
                      PWD    = rstudioapi::askForPassword("Database password"),
                      Port   = 1521)

Known Issues

This section will be updated as new issues are found, and when fixes are applied in the development version of the dbplyr package. The issue will be fully removed when the fix is part of of the package’s version in CRAN.

  • Retrieving the top records, in instances when head() is used or when a tibble prints a preview of the dataset, only works with version 12c (Issue 2928)

  • RJDBC support - Even though it is not considered an issue, we have found a workaround. The approach is to point the current JDBC connection to the Oracle translation inside dbplyr:

      sql_translate_env.JDBCConnection <- dbplyr:::sql_translate_env.Oracle
      sql_select.JDBCConnection <- dbplyr:::sql_select.Oracle
      sql_subquery.JDBCConnection <- dbplyr:::sql_subquery.Oracle
