ODBC Call-level Interface

The ODBC Call-level Interface (ODBC CLI) provides access to the ODBC application environment without the need to use third-party software. It is installed when you install the ODBC Driver.

The ODBC CLI performs these functions:

  • Optionally determines driver characteristics from ODBC configuration files

  • Loads and unloads the ODBC driver into and from application memory

  • Maps the driver manager API to the driver API

  • Performs basic error checking

  • Provides thread safety

  • Provides ODBC tracing

  • Provides function templates, type definitions, and constant definitions for ODBC applications

  • Provides connection pooling, which allows connections to be shared in ODBC applications

Note

The ODBC CLI is not a generic ODBC driver manager. While it does provide functions similar to other ODBC driver managers, it is designed specifically to support ODBC-based application access. It does not support ODBC drivers provided by third-party vendors.

The ODBC CLI is available on all supported platforms except Windows. The iiodbcadmin utility configures ODBC Data Source Definitions for the CLI. For more information, see Configure a Data Source (Linux).
