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
