ResultSet

java.sql.ResultSet
Known Indirect Subclasses

Class Overview

An interface to an Object which represents a Table of Data, typically returned as the result of a Query to a Database.

ResultSets have a Cursor which points to a current row of data. When a ResultSet is created, the Cursor is positioned before the first row. To move the Cursor to the next row in the table, use the next method. The next method returns true until there are no more rows in the ResultSet, when it returns false.

The default type of ResultSet cannot be updated and its cursor can only move forward through the rows of data. This means that it is only possible to read through it once. However, it is possible to create types of ResultSet that can be updated and also types where the cursor can be scrolled forward and backward through the rows of data. This is shown in the following code example: Connection con; Statement aStatement = con.createStatement( ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE ); ResultSet theResultSet = theStatement.executeQuery("SELECT price, quantity FROM STOCKTABLE"); // theResultSet will be both scrollable and updateable

The ResultSet interface provides a series of methods for retrieving data from columns in the current row, such as getDate, getFloat. The columns are identified either by their index number (starting at 1) or by their name - there are separate methods for both techniques of column addressing. The column names are case insensitive. If several columns have the same name, then the getter methods use the first matching column. This means that if column names are used, it is not possible to guarantee that the name will retrieve data from the intended column - for certainty it is better to use column indexes. Ideally the columns should be read left-to-right and read once only, since not all * databases are optimized to handle other techniques of reading the data.

When reading data, the JDBC driver maps the SQL data retrieved from the database to the Java type implied by the method invoked by the application. The JDBC specification has a table of allowable mappings from SQL types to Java types.

There are also methods for writing data into the ResultSet, such as updateInt, updateString. The update methods can be used either to modify the data of an existing row or to insert new data rows into the ResultSet. Modification of existing data involves moving the Cursor to the row which needs modification and then using the update methods to modify the data, followed by calling the ResultSet.updateRow method. For insertion of new rows, the cursor is first moved to a special row called the Insert Row, data is added using the update methods, followed by calling the ResultSet.insertRow method.

A ResultSet is closed if the Statement object which generated it closed, executed again or is used to retrieve the next result from a sequence of results.
