ODBC Driver for Greenplum

Build 21.0.7930

From R

This section provides a walk-through to writing ODBC data access code to Greenplum in R, using the RODBC module.

Connecting from R

See Getting Started for the prerequisite information you need to deploy the driver and configure the connection to Greenplum.

Dependencies describes the necessary steps to install RODBC. Once it is prepared, refer to Connecting to connect to Greenplum.

Executing SQL

Use RODBC functions to execute SQL on Greenplum:

  • See Querying Data to execute SELECT statements and iterate over the results.
  • See Updating Data to execute other SQL data manipulation statements.
  • See Parameterized Statements to execute parameterized statements. Parameterized statements provide a means to efficiently execute queries more than once and to mitigate SQL injection attacks.

Executing Stored Procedures

See Executing Stored Procedures to execute stored procedures as SQL statements.
