Development Based on ODBC

Open Database Connectivity (ODBC) is a Microsoft API for accessing databases based on the X/OPEN CLI. ODBC APIs alleviate applications from directly operating in databases, and enhance the database portability, extensibility, and maintainability.

Figure 1 shows the system structure of ODBC.

GaussDB supports ODBC 3.5 in the following environments.

The ODBC Driver Manager running on Unix or Linux can be unixODBC or iODBC. unixODBC-2.3.7 is used as the component for connecting to the database.

Windows has a native ODBC Driver Manager. You can locate Data Sources (ODBC) by choosing Control Panel > Administrative Tools.

The current database ODBC driver is based on an open-source version and may be incompatible with Huawei-developed data types such as tinyint, smalldatetime, and nvarchar2.
