This section provides a reference to ODBC compliance and a walk-through to writing ODBC data access code to Parquet in C/C++.

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 C/C++

See Getting Started for the prerequisite information you need to deploy the driver and configure the connection to Parquet. Connecting shows how to connect with ODBC functions.

Executing SQL

Use ODBC functions to execute SQL to Parquet:

• 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.
• See Batch Processing to take advantage of the bulk processing functionality in Parquet. The driver converts the ODBC batch commands into a single request to Parquet.
• See Discovering Schemas to obtain schema information, such as the available tables, columns, keys, and types. See Data Model to obtain the driver metadata by querying the available system tables.
