JDBC Example – Batch Update using PreparedStatement


Using Batch Update feature of PreparedStatement you can Insert, Update or Delete multiple records with single database hit. For example if you want to insert multiple records into database using Batch Update you will just need to conect to database once. You can loop through records and add it to bach and once done you can execute the bach i.e insert all records in a single shot.


Below is a code snippet which shows how to insert few records in batch process, via JDBC PreparedStatement

PreparedStatement ps=con.prepareStatement("INSERT INTO BS_Books (cat_id,book_title,book_details,book_price,book_author) values (?,?,?,?,?)");

ps.setInt(1, 1);
ps.setString(2, "Book1");
ps.setString(3, "Details of book1");
ps.setDouble(4, 100.0);
ps.setString(5, "Author1");
ps.addBatch();//Adding record to the batch

ps.setInt(1, 1);
ps.setString(2, "Book2");
ps.setString(3, "Details of book2");
ps.setDouble(4, 150.0);
ps.setString(5, "Author2");
ps.addBatch();//Adding record to the batch

ps.executeBatch();//Executing the batch

Please see the complete self explanatory java code below
