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

See Data Model for more information on the available API objects and any API limitations or requirements. See SQL Compliance for the SQL syntax.

Connecting from R

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

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

Executing SQL

Use RODBC functions to execute SQL on Google Data Catalog:

• See Querying Data to execute SELECT statements and iterate over the results.
• 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.
