A table of data representing a database result set, which
is usually generated by executing a statement that queries the database.
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 (Java™ 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:
- to update a column value in the current row. In a scrollable
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
- to insert column values into the insert row. An updatable
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 column 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 ResultSetMetaData
object returned by the ResultSet.getMetaData
method.

public interface ResultSet extends Wrapper, AutoCloseable {
Moves the cursor forward one row from its current position.
A ResultSet
cursor is initially positioned
before the first row; the first call to the method
next
makes the first row the current row; the
second call makes the second row the current row, and so on.
When a call to the next
method returns false
,
the cursor is positioned after the last row. Any
invocation of a ResultSet
method which requires a
current row will result in a SQLException
being thrown.
If the result set type is TYPE_FORWARD_ONLY
, it is vendor specified
whether their JDBC driver implementation will return false
or
throw an SQLException
on a
subsequent call to next
.
If an input stream is open for the current row, a call
to the method next
will
implicitly close it. A ResultSet
object's
warning chain is cleared when a new row is read.
Throws: - SQLException – if a database access error occurs or this method is
called on a closed result set
Returns: true
if the new current row is valid;
false
if there are no more rows

Retrieves the name of the SQL cursor used by this ResultSet
object.
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
FOR UPDATE
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.
Throws: - SQLException – if a database access error occurs or this method is called on a closed result set
- SQLFeatureNotSupportedException – if the JDBC driver does not support
this method

If the given row number is negative, the cursor moves to

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.
If the row number specified is zero, the cursor is moved to
before the first row.
An attempt to position the cursor beyond the first/last row in
the result set leaves the cursor before the first row or after

Note: Calling absolute(1)

Moves the cursor to the previous row in this
