    <p>i'm having a trouble with the next() method when i try to insert a values to table from the the while(sr.next()) it throw ResultSet Exception but when i'm removing the insert query from the body of the while it work so why the ResultSet is closed when i'm training to insert values in the while body here is the code </p> <pre><code>import java.io.IOException; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.Scanner; public class SqlServerJDBC { public static void main(String[] args) throws IOException { String line, dis; float totalPrice = 0; Scanner scan= new Scanner(System.in); try { Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); System.out.println("# - Driver Loaded"); Connection con = DriverManager.getConnection("jdbc:odbc:books_DSN"); System.out.println("# - Connection Obtained"); Statement stmt = con.createStatement(); System.out.println("# - Statement Created"); String createTableOrder = "create table viewOrder" + "(title_name VARCHAR(40)," + "price DECIMAL(5,2)," + "pages INT," + "au_fname VARCHAR(15)," + "au_lname VARCHAR(15)," + "pub_name VARCHAR(20)," + "city VARCHAR(15)," + "country VARCHAR(15))"; stmt.executeUpdate(createTableOrder); System.out.println("Created table in given database..."); ResultSet rs = stmt.executeQuery("SELECT title_name,price FROM titless"); System.out.println("# - Query Executed\n"); while(rs.next()){ System.out.println("title: " +rs.getString("title_name") + "\tprice: " + rs.getFloat("price")); } do { System.out.println("\nEnter the name of the book..."); line = scan.nextLine(); rs = stmt.executeQuery("select title_name,price,pages,au_fname" + ",au_lname,pub_name,authorss.city,country " + " from titless inner join title_authorss on titless.title_id = title_authorss.title_id " + " inner join authorss on title_authorss.au_id = authorss.au_id" + " inner join publisherss on publisherss.pub_id = titless.pub_id" + " where titless.title_name like "+"'"+line+"'"); /*here is the problem */ while(rs.next()){ String insertIntoTableOrder =("INSERT INTO viewOrder " + " VALUES ('"+rs.getString("title_name")+"',"+rs.getFloat("price")+","+rs.getInt("pages")+"" + ",'"+rs.getString("au_fname")+"','"+rs.getString("au_lname")+"'," + "'"+rs.getString("pub_name")+"','"+rs.getString("city")+"','"+rs.getString("country")+"')"); stmt.executeUpdate(insertIntoTableOrder); totalPrice = totalPrice + rs.getFloat("price"); } System.out.println("Total Price = " + totalPrice); System.out.println("Do you want add more books ??"); System.out.println("Y/N..."); dis = scan.nextLine(); } while (dis.equalsIgnoreCase("y")); con.close(); stmt.close(); rs.close(); System.out.println("# - Resources released"); } catch (SQLException | ClassNotFoundException ex) { System.out.println("Error : "+ex); } } } </code></pre> <p><img src="https://i.stack.imgur.com/TQfAp.png" alt="here is the output"></p>

    1. COyou close your while loop before even to get e chance to get rs.next()

    2. COIt seems that you are running executeQuery on the same ResultSet object while inside the rs.next while loop. Is there a reason for this? Maybe if you used a different ResultSet object it would solve this problem?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
