### Question:
MysqlLoader extends BaseLoader { public MysqlLoader(DataSource dataSource, String jdbcUrl, String tableName, String columnName) throws Exception { super(dataSource, jdbcUrl, tableName, columnName); } MysqlLoader(DataSource dataSource, String jdbcUrl, String tableName, String columnName); @Override String insertStatement(); @Override String loadStatement(); @Override String deleteStatement();  }### Answer:
@Test @Ignore public void testMysqlLoader() throws Exception { ComboPooledDataSource ds = new ComboPooledDataSource(); ds.setJdbcUrl("jdbc:mysql: MysqlLoader loader = new MysqlLoader(ds, "jdbc:mysql: "array"); loader.delete("1"); INDArray load = loader.load(loader.loadForID("1")); if (load != null) { loader.delete("1"); } loader.save(Nd4j.create(new float[] {1, 2, 3}), "1"); Blob b = loader.loadForID("1"); INDArray loaded = loader.load(b); assertEquals((Nd4j.create(new float[] {1, 2, 3})), loaded); }
