You can change the value of a column in the current row of the resultset by calling the updateXXX() method, where XXX is replaced with the data type of the column you re updating The updateXXX() method requires two parameters The first parameter indicates the column of the current row whose value is being changed You indicate the column in one of two ways You can use the number of the column or the column name Some programmers prefer to use the column name rather than the column number because they don t have to be concerned with the column sequence The second parameter of the updateXXX() method is the new value that will override the current value of the column in the current row

Sometimes you ll want to simply leave the column empty You do this by calling the updateNull() method A null value, as you ll recall, is another way of saying that the column is empty The updateNull() method requires one parameter, which is the column number whose contents will become null The updateNull() method doesn t accept the name of the column as a parameter Once the updateXXX() method is called, you ll need to call the updateRow() method The updateRow() method changes the values in the columns of the current row of the resultset based on the values of the updateXXX() methods The following example shows how to update a resultset In this example, Mary Jones was recently married and changed her last name to Smith The updateString() method is used to change the value of the last name column of the resultset to 'Jones' The change takes effect once the updateRow() method is called

You can remove a row from the resultset by calling the deleteRow() method Programmers frequently use this method to pare down the number of rows that must be processed by their program Those rows that shouldn t be processed are eliminated from the resultset rather than you having to refine the SQL query selection criteria and rerun the SQL query The deleteRow() method requires one parameter an integer that indicates the row number of the row being deleted Typically, a programmer moves the virtual cursor to the row in the resultset that is to be deleted Before deleting the row, however, the programmer usually examines the values in relative columns in order to be sure that the row should be deleted Once you re sure the current row is the row you want deleted, you call the deleteRow() method, as shown here:
ResultsdeleteRow();
Inserting a Row in the Resultset
You might have a need to incorporate a row of your own data into the resultset supplied by the DBMS You can do this by inserting a new row in the resultset Keep in mind that you still need to write and execute an SQL query to insert a new row into the underlying table in the database if you want or need data to be contained in the table
