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

Connecting from C/C++

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

Executing SQL

Use ODBC functions to execute SQL to Informix:

• 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 Discovering Schemas to obtain schema information, such as the available tables, columns, keys, and types.

Executing Stored Procedures

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