public final class ResultSetWrapper
extends java.lang.Object
implements java.sql.ResultSet
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, it is possible to iterate through it only
once and only from the first row to the last row. New methods in the JDBC
2.0 API make it 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 getXXX
methods 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 getXXX methods, a JDBC driver attempts to convert the
underlying data to the Java type specified in the XXX part of
the getXXX method and returns a suitable Java value. The JDBC
specification has a table showing the allowable mappings from SQL types to
Java types with the ResultSet.getXXX methods.
Column names used as input to getXXX methods are case
insensitive. When a getXXX 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, there is no way for the programmer to
guarantee that they actually refer to the intended columns.
A set of updateXXX 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 getXXX
methods also apply to parameters to the updateXXX methods.
The updateXXX 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 be 35
rs.updateBoolean(3, true); // updates the third row to true
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 ResulSetMetaData object returned by
the ResultSet.getMetaData method.

ResultSet

In SQL, a result table is retrieved through a cursor that is named. The
current row of a result set can be updated or deleted using a positioned
update/delete statement that references the cursor name. To insure that
the cursor has the proper isolation level to support update, the
cursor's select statement should be of the form 'select for
update'. If the 'for update' clause is omitted, the positioned updates
may fail.
The JDBC API supports this SQL feature by providing the name of the SQL
cursor used by a ResultSet object. The current row of a
ResultSet object is also the current row of this SQL
cursor.
Note: If positioned update is not supported, a SQLException
is thrown.

is extended to materialize data of SQL user-defined types. When a column

If the given row number is negative, the cursor moves to an absolute row
position with respect to the end of the result set. For example, calling
the method absolute(-1) positions the cursor on the last
row; calling the method absolute(-2) moves the cursor to
the next-to-last row, and so on.
An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.
Note: Calling absolute(1) is the same as calling
first(). Calling absolute(-1) is the same as
calling last().

The refreshRow method provides a way for an application to
explicitly tell the JDBC driver to refetch a row(s) from the database.
An application may want to call refreshRow when caching or
prefetching is being done by the JDBC driver to fetch the latest value
of a row from the database. The JDBC driver may actually refresh
multiple rows at once if the fetch size is greater than one.
All values are refetched subject to the transaction isolation level and
cursor sensitivity. If refreshRow is called after calling
an updateXXX method, but before calling the method updateRow
, then the updates made to the row are lost. Calling the method refreshRow
frequently will likely slow performance.
