ODBC database connection library
This library has a total of 25 functions
Open Database Connectivity (ODBC) is a connection database common interface. ODBC is a database connection standard led by Microsoft, and Microsoft's system is the most mature implementation environment. In UNIX systems, ODBC interfaces provided by other vendors are usually used. Some UNIX vendors provide their own ODBC interfaces (for example, SUN provides ODBC for Solaris).
ODBC and database queries use SQL language, which is the same as most database queries, which makes the system easy to communicate with various databases. Of course, through the ODBC interface, the back-end database does not have to be a large database system such as DBMS. It can also be a data table (such as Microsoft Access) or a spreadsheet (such as Microsoft Excel).
