Examples of org.apache.metamodel.delete.DeleteFrom

org.apache.metamodel.delete.DeleteFrom
Represents a single DELETE FROM operation to be applied to a {@link UpdateableDataContext}. Instead of providing a custom implementation of the {@link UpdateScript} interface, one can use this pre-built delete fromimplementation. Some {@link DataContext}s may even optimize specifically based on the knowledge that there will only be a single delete from statement executed.

                assertTrue(dateValueFromDataSet instanceof Date);
                assertEquals("1980-08-08 00:00:00", dateFormat.format(dateValueFromDataSet));


            } finally {
                // clean up
                dc.executeUpdate(new DeleteFrom(table).where("Id").eq(id));
            }


            rows++;
        }
