SQLG is a preprocessor and a library that uses code generation to simplify writing JDBC code

There is a newer version: 3.1

 * This class can be used to call SQLG code from JDBC code. If you have {@link Connection} instance then

 *  * Connection conn = ...;
 * ISimpleTransaction trans = new JdbcInterface(global, conn, false);
 * ITest iface = trans.getInterface(ITest.class);
