Question

I have a file with records.

I have to develop a spring batch program which will read the file and DELETE the same records from the database table.

Is it possible to run delete query through ItemWriter ???

Answer 1

There is no difference between update or delete operations, only the sql changes; so simple answer to your question will be yes.
The following code fragment may help for basic needs assuming that you are deleting from the Book table.

public class BookJdbcItemWriter implements ItemWriter<Book> {

        private static final String DELETE_BOOK = "delete from Book where id = ?";

        private JdbcTemplate jdbcTemplate;

        public BookJdbcItemWriter(DataSource dataSource) {
                this.jdbcTemplate = new JdbcTemplate(dataSource);
        }

        public void write(List<? extends Book> items) throws Exception {
                for(Book item : items) {
                        int updated = jdbcTemplate.update(DELETE_BOOK,item.getId());                                                           
                }
        }
}
