A ResultSet object maintains a cursor pointing
* to its current row of data. Initially the cursor is positioned
* before the first row. The next method moves the
* cursor to the next row, and because it returns false
* when there are no more rows in the ResultSet object,
* it can be used in a while loop to iterate through
* the result set.
*
* A default ResultSet 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 ResultSet objects that are scrollable and/or
* updatable. The following code fragment, in which con
* is a valid Connection object, illustrates how to make
* a result set that is scrollable and insensitive to updates by others, and
* that is updatable. See ResultSet fields for other
* options.
*
*
* 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
*
*
* The ResultSet interface provides
* getter methods (getBoolean, getLong, 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.
*
* 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 ResultSet getter methods.
*
*
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 AS clause. *
* A set of updater methods were added to this interface * in the JDBC 2.0 API (JavaTM 2 SDK, * Standard Edition, version 1.2). The comments regarding parameters * to the getter methods also apply to parameters to the * updater methods. *
* The updater methods may be used in two ways: *
ResultSet 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 NAME column
* in the fifth row of the ResultSet object
* rs and then uses the method updateRow
* to update the data source table from which rs was derived.
*
*
* rs.absolute(5); // moves the cursor to the fifth row of rs
* rs.updateString("NAME", "AINSWORTH"); // updates the
* // NAME column of row 5 to be AINSWORTH
* rs.updateRow(); // updates the row in the data source
*
*
* ResultSet 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 rs and into
* the data source table using the method insertRow.
* * * rs.moveToInsertRow(); // moves cursor to the insert row * rs.updateString(1, "AINSWORTH"); // updates the * // first column of the insert row to be*AINSWORTH* rs.updateInt(2,35); // updates the second column to be35* rs.updateBoolean(3, true); // updates the third column totrue* rs.insertRow(); * rs.moveToCurrentRow(); * *
A ResultSet object is automatically closed when the
* Statement object that
* generated it is closed, re-executed, or used
* to retrieve the next result from a sequence of multiple results.
*
*
The number, types and properties of a ResultSet
* object's columns are provided by the ResultSetMetaData
* object returned by the ResultSet.getMetaData method.
