Oracle

Driver Options

  • Oracle - Please refer to Oracle’s website for instructions on how to download and setup their official driver: Oracle ODBC driver page

  • RStudio Professional Drivers - RStudio Server Pro, RStudio Connect, or Shiny Server Pro users can download and use RStudio Professional Drivers at no additional charge. These drivers include an ODBC connector for Oracle databases. RStudio delivers standards-based, supported, professional ODBC drivers. Use RStudio Professional Drivers when you run R or Shiny with your production systems. See the RStudio Professional Drivers for more information.

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 six 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)

dplyr Translation

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

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