Initially the cursor is positioned * before the first row. The <code>next</code> method moves the * cursor to the next row, and because it returns <code>false</code> * when there are no more rows in the <code>ResultSet</code> object, * it can be used in a <code>while</code> loop to iterate through * the result set. * <P> * A default <code>ResultSet</code> object is not updatable and * has a cursor that moves forward only. Thus, you can * iterate through it only once and only from the first row to the * last row. It is possible to * produce <code>ResultSet</code> objects that are scrollable and/or * updatable. The following code fragment, in which <code>con</code> * is a valid <code>Connection</code> object, illustrates how to make * a result set that is scrollable and insensitive to updates by others, and * that is updatable. See <code>ResultSet</code> fields for other * options. * <PRE> * * Statement stmt = con.createStatement( * ResultSet.TYPE_SCROLL_INSENSITIVE, * ResultSet.CONCUR_UPDATABLE); * ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2"); * // rs will be scrollable, will not show changes made by others, * // and will be updatable * * </PRE> * The <code>ResultSet</code> interface provides * <i>getter</i> methods (<code>getBoolean</code>, <code>getLong</code>, and so on) * for retrieving column values from the current row. * Values can be retrieved using either the index number of the * column or the name of the column. In general, using the * column index will be more efficient. Columns are numbered from 1. * For maximum portability, result set columns within each row should be * read in left-to-right order, and each column should be read only once. * * <P>For the getter methods, a JDBC driver attempts * to convert the underlying data to the Java type specified in the * getter method and returns a suitable Java value. The JDBC specification * has a table showing the allowable mappings from SQL types to Java types * that can be used by the <code>ResultSet</code> getter methods. * * <P>Column names used as input to getter methods are case * insensitive. When a getter method is called with * a column name and several columns have the same name, * the value of the first matching column will be returned. * The column name option is * designed to be used when column names are used in the SQL * query that generated the result set. * For columns that are NOT explicitly named in the query, it * is best to use column numbers. If column names are used, the * programmer should take care to guarantee that they uniquely refer to * the intended columns, which can be assured with the SQL <i>AS</i> clause. * <P> * A set of updater methods were added to this interface * in the JDBC 2.0 API (Java™ 2 SDK, * Standard Edition, version 1.2). The comments regarding parameters * to the getter methods also apply to parameters to the * updater methods. *<P> * The updater methods may be used in two ways: * <ol> * <LI>to update a column value in the current row. In a scrollable * <code>ResultSet</code> object, the cursor can be moved backwards * and forwards, to an absolute position, or to a position * relative to the current row. * The following code fragment updates the <code>NAME</code> column * in the fifth row of the <code>ResultSet</code> object * <code>rs</code> and then uses the method <code>updateRow</code> * to update the data source table from which <code>rs</code> was derived. * <PRE> * * rs.absolute(5); // moves the cursor to the fifth row of rs * rs.updateString("NAME", "AINSWORTH"); // updates the * // <code>NAME</code> column of row 5 to be <code>AINSWORTH</code> * rs.updateRow(); // updates the row in the data source * * </PRE> * <LI>to insert column values into the insert row. An updatable * <code>ResultSet</code> object has a special row associated with * it that serves as a staging area for building a row to be inserted. * The following code fragment moves the cursor to the insert row, builds * a three-column row, and inserts it into <code>rs</code> and into * the data source table using the method <code>insertRow</code>. * <PRE> * * rs.moveToInsertRow(); // moves cursor to the insert row * rs.updateString(1, "AINSWORTH"); // updates the * // first column of the insert row to be <code>AINSWORTH</code> * rs.updateInt(2,35); // updates the second column to be <code>35</code> * rs.updateBoolean(3, true); // updates the third column to <code>true</code> * rs.insertRow(); * rs.moveToCurrentRow(); * * </PRE> * </ol> * <P>A <code>ResultSet</code> object is automatically closed when the * <code>Statement</code> object that * generated it is closed, re-executed, or used * to retrieve the next result from a sequence of multiple results. * * <P>The number, types and properties of a <code>ResultSet</code> * object's columns are provided by the <code>ResultSetMetaData</code> * object returned by the <code>ResultSet.getMetaData</code> method. * * @see Statement#executeQuery * @see Statement#getResultSet * @see ResultSetMetaData * @since 1.1 */ public interface ResultSet extends Wrapper, AutoCloseable { /** * Moves the cursor forward one row from its current position. * A <code>ResultSet</code> cursor is initially positioned * before the first row; the first call to the method * <code>next</code> makes the first row the current row; the * second call makes the second row the current row, and so on. * <p> * When a call to the <code>next</code> method returns <code>false</code>, * the cursor is positioned after the last row.
