This section provides a walk-through to writing ODBC data access code to Apache Impala in Node.js, using the node-odbc package.

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 Node.js

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

Dependencies describes the necessary steps to install the node-odbc package. Once it is installed, refer to Connecting to connect to Apache Impala.

Executing SQL

Use node-odbc functions to execute SQL on Apache Impala:

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