ODBC backend factory together with a connection string:
-BackEndFactory const &backEnd = odbc; -Session sql(backEnd, "filedsn=c:\\my.dsn"); +backend_factory const& backEnd = odbc; +session sql(backEnd, "filedsn=c:\\my.dsn");
or simply:
-Session sql(odbc, "filedsn=c:\\my.dsn"); +session sql(odbc, "filedsn=c:\\my.dsn");
The set of parameters used in the connection string for ODBC is the same as accepted by the SQLDriverConnect function from the ODBC library.
Once you have created a Session object as shown above, you can use it to access the database, for example:

The ODBC backend supports the use of the SOCI Row class, which facilitates retrieval of data whose type is not known at compile time.
The ODBC backend supports the use of the SOCI row class, which facilitates retrieval of data whose type is not known at compile time.
When calling Row::get<T>(), the type you should pass as T depends upon the underlying database type.
