Java ResultSet deleteRow() method with example

JDBCJava 8Object Oriented ProgrammingProgramming

When we execute certain SQL queries (SELECT query in general) they return tabular data.

The java.sql.ResultSet interface represents such tabular data returned by the SQL statements.

i.e. the ResultSet object holds the tabular data returned by the methods that execute the statements which quires the database (executeQuery() method of the Statement interface in general).

The ResultSet object has a cursor/pointer which points to the current row. Initially this cursor is positioned before first row.

The deleteRow() method of the ResultSet interface deletes the current row from the ResultSet object and from the table.


Let us create a table with name MyPlayers in MySQL database using CREATE statement as shown below: 

   ID INT,
   First_Name VARCHAR(255),
   Last_Name VARCHAR(255),
   Date_Of_Birth date,
   Place_Of_Birth VARCHAR(255),
   Country VARCHAR(255),

Now, we will insert 7 records in MyPlayers table using INSERT statements:

insert into MyPlayers values(1, 'Shikhar', 'Dhawan', DATE('1981-12-05'), 'Delhi', 'India');
insert into MyPlayers values(2, 'Jonathan', 'Trott', DATE('1981-04-22'), 'CapeTown', 'SouthAfrica');
insert into MyPlayers values(3, 'Kumara', 'Sangakkara', DATE('1977-10-27'), 'Matale', 'Srilanka');
insert into MyPlayers values(4, 'Virat', 'Kohli', DATE('1988-11-05'), 'Delhi', 'India');
insert into MyPlayers values(5, 'Rohit', 'Sharma', DATE('1987-04-30'), 'Nagpur', 'India');
insert into MyPlayers values(6, 'Ravindra', 'Jadeja', DATE('1988-12-06'), 'Nagpur', 'India');
insert into MyPlayers values(7, 'James', 'Anderson', DATE('1982-06-30'), 'Burnley', 'England');

Following JDBC program establishes connection with the database, deletes the last record from the Myplayers table and prints the contents of the table after the delete operation.

      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
      System.out.println("Connection established......");
      //Creating the Statement
      Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
      //Query to retrieve records
      String query = "Select * from MyPlayers";
      //Executing the query
      ResultSet rs = stmt.executeQuery(query);
      //Moving the pointer to last row
      //Removing the current row from the ResultSet
      System.out.println("Contents of the table after deleting a row: ");
      while( {
         System.out.print("ID: "+rs.getInt("ID")+", ");
         System.out.print("Name: "+rs.getString("First_Name")+", ");
         System.out.print("Age: "+rs.getString("Last_Name")+", ");
         System.out.print("Salary: "+rs.getDate("Date_Of_Birth")+", ");
         System.out.print("Country: "+rs.getString("Place_Of_Birth")+", ");
         System.out.print("Address: "+rs.getString("Country"));
