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. (JDBC4 clarification:) 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.



HSQLDB-Specific Information:
 

A ResultSet object generated by HSQLDB is by default of
ResultSet.TYPE_FORWARD_ONLY (as is standard JDBC behavior)
and does not allow the use of absolute and relative positioning
methods.  If a statement is created with:
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);

then the ResultSet objects it produces support
using all of  the absolute and relative positioning methods of JDBC2
to set the position of the current row, for example:
rs.absolute(5);
String fifthRowValue = rs.getString(1);
rs.relative(4);
String ninthRowValue = rs.getString(1);

Note: An HSQLDB ResultSet object persists, even after its connection is closed. This is regardless of the operational mode of the Database from which it came. That is, they persist whether originating from a Server,
WebServer or in-process mode Database.
 From HSQLDB 2.0, there is full support for updatable result sets. Supported methods include all updateXXX methods for the supported types, as well as the insertRow, updateRow, deleteRow, moveToInsertRow methods.

The Statement must be created with ResultSet.CONCUR_UPDATABLE instead of
CONCUR_READ_ONLY.
 Updatability of a result set follows the SQL standards. Some or all columns of an updatable result set can be updated. The current row in such result sets can be deleted using the deleteRow method. Some updatable result set can also be inserted into and support moveToInsertRow.

A result set is updatable if the SELECT statement
is updatable. This includes SELECT from TABLE and updatable VIEW objects.
An updatable SELECT statement has a single underlying table or view.
HSQLDB supports both scrollable and forward-only result sets for updatability.
-- In the SELECT below, columns A and B are updatable, any row can be
-- deleted, but it is not insertable-into as column C is not directly from
-- the table.
SELECT A, B, A + B AS C FROM T WHERE ...
-- The SELECT below can be insertable-into so long as other columns of the
-- table that do not appear in the SELECT list have a default value.
SELECT A, B FROM T WHERE ...

Moves the cursor froward 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.
(JDBC4 clarification:)
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.

this to happen when it is automatically closed.
(JDBC4 clarification:)
The closing of a ResultSet object does not close the Blob,
Clob or NClob objects created by the ResultSet. Blob,
Clob or NClob objects remain valid for at least the duration of the
transaction in which they are created, unless their free method is invoked.

(JDBC4 clarification:)
When a ResultSet is closed, any ResultSetMetaData
instances that were created by calling the  getMetaData
method remain accessible.
Note: A ResultSet object

Statement object that generated it when
that Statement object is closed,
re-executed, or is used to retrieve the next result from a
sequence of multiple results.
(JDBC4 deleted:) [A ResultSet object is also automatically
closed when it is garbage collected.]

Calling the method close on a ResultSet
object that is already closed is a no-op.

Retrieves the value of the designated column in the current row
of this ResultSet object as
a stream of ASCII characters. The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARCHAR values.
The JDBC driver will
do any necessary conversion from the database format into ASCII.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream.  Also, a
stream may return 0 when the method
InputStream.available
is called whether there is data available or not.



HSQLDB-Specific Information:
 

The limitation noted above does not apply to HSQLDB.

When the column is of type CHAR and its variations, it requires no
conversion since it is represented internally already as a
Java String object. When the column is not of type CHAR and its
variations, the returned stream is based on a conversion to the
Java String representation of the value. In either case,
the obtained stream is always equivalent to a stream of the low order
bytes from the value's String representation. 

HSQLDB SQL CHAR and its variations are all Unicode strings internally, so the recommended alternatives to this method are getString, getUnicodeStream (deprecated) and new to 1.7.0: getCharacterStream (now preferred over the deprecated getUnicodeStream alternative).

Retrieves the first warning reported by calls on this
ResultSet object.
Subsequent warnings on this ResultSet object
will be chained to the SQLWarning object that
this method returns.
The warning chain is automatically cleared each time a new
row is read.  This method may not be called on a ResultSet
object that has been closed; doing so will cause an
SQLException to be thrown.

Note: This warning chain only covers warnings caused
by ResultSet methods.  Any warning caused by
Statement methods
(such as reading OUT parameters) will be chained on the
Statement object.

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.



HSQLDB-Specific Information:
 

HSQLDB supports this feature when the cursor has a name.

Retrieves the  number, types and properties of
this ResultSet object's columns.



HSQLDB-Specific Information:
 

Example: 

The following code fragment creates a ResultSet object rs,
creates a ResultSetMetaData object rsmd, and uses rsmd
to find out how many columns rs has and whether the first column
in rs can be used in a WHERE clause.
ResultSet rs   = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();

int numberOfColumns = rsmd.getColumnCount();

boolean b = rsmd.isSearchable(1);



Changes: 

With version 2.0, the engine's SQL implementation has been
completely rewritten. Changes to this class and the implementation of
ResultSetMetaData reflect the engine's new capabilities and provide
more accurate information. 

changes to consider:

isAutoIncrement(int) always returned false
isNullable(int) returns the nullability of a real table or view
    column in the ResultSet and returns
    columnNoNulls for non-base-column ResultSet columns
    (columns of the ResultSet that are based on expressions or
    aggregates).
getColumnDisplaySize(int) returns correct results even for expression
    columns.
getPrecision(int) returns the correct precision even for expression
    columns.
getScale(int) returns the correct precision even for expression
    columns.
getCatalogName(int) returns the catalog name of the database.

HSQLDB-Specific Information:
 

Starting with 1.9.x, HSQLDB does an exhaustive search, backed by
a cache lookup (to improve performance for subsequent invocations with
a given input). 

Upon careful investigation of the JDBC specification and the behaviour
of existing JDBC drivers, there is actually nothing preventing the
findColumn method from doing an exhaustive search, as long as it conforms
to the following rules (which describe the new implementation):

 the entire search is case insensitive
 each search iteration occurs from leftmost to rightmost column,
     returning the first match encountered
 the first pass matches only bare column labels
 the second pass matches only simple column names
 further passes conform to the identifier qualification
     and identifier quoting rules of the engine

In this implementation, the SQL tokenizer is not employed, both because
it does not yet correctly handle greater than two part qualification
and also because is is not immediately considered important to do a
truly exhaustive search, handling the full range of possibly mixed quoted
and unquoted identifier components. 

Instead:

 a third pass matches simple table-dot-column qualified names
 a fourth pass matches simple schema-dot-table-dot-column qualified column names


Params:
columnLabel – the label for the column specified with the SQL AS clause.  If the SQL AS clause was not specified, then the label is the name of the column
Throws:
SQLException – if the ResultSet object
does not contain a column labeled columnLabel, a database access error occurs
 or this method is called on a closed result set

Moves the cursor to the given row number in
this ResultSet object.
If the row number is positive, the cursor moves to
the given row number with respect to the
beginning of the result set.  The first row is row 1, the second
is row 2, and so on.
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().

Params:
row – the number of the row to which the cursor should move.

Moves the cursor to the previous row in this

(JDBC4 clarification:)
When a call to the previous method returns false,

(JDBC clarification:)
If the second argument is an InputStream then the stream must contain
the number of bytes specified by scaleOrLength.  If the second argument is a
Reader then the reader must contain the number of characters specified
by scaleOrLength. If these conditions are not true the driver will generate a
SQLException when the statement is executed.

Refreshes the current row with its most recent value in
the database.  This method cannot be called when
the cursor is on the insert row.
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 updater 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.

Moves the cursor to the insert row.  The current cursor position is
remembered while the cursor is positioned on the insert row.
The insert row is a special row associated with an updatable
result set.  It is essentially a buffer where a new row may
be constructed by calling the updater methods prior to
inserting the row into the result set.
Only the updater, getter,
and insertRow methods may be
called when the cursor is on the insert row.  All of the columns in
a result set must be given a value each time this method is
called before calling insertRow.
An updater method must be called before a

This method uses the given calendar to construct an appropriate millisecond
value for the timestamp if the underlying database does not store
timezone information.

specification as follows:

If the SQL type of the column is WITH TIME ZONE, then the UTC value
of the returned java.sql.Timestamp object is the UTC of the SQL value
without modification. In other words, the Calendar object is not used.

If the SQL type of the column is WITHOUT TIME ZONE, then the UTC
value of the returned java.sql.Timestamp is correct for the given
Calendar object.
If the cal argument is null, it it ignored and the method returns
the same Object as the method without the Calendar parameter.

Updates the designated column using the given Reader
object, which is the given number of characters long.
When a very large UNICODE value is input to a LONGVARCHAR
parameter, it may be more practical to send it via a
java.io.Reader object. The data will be read from the stream
as needed until end-of-file is reached.  The JDBC driver will
do any necessary conversion from UNICODE to the database char format.
Note: This stream object can either be a standard
Java stream object or your own subclass that implements the
standard interface.

The updater methods are used to update column values in the
current row or the insert row.  The updater methods do not
update the underlying database; instead the updateRow or
insertRow methods are called to update the database.
Params:
columnLabel – the label for the column specified with the SQL AS
clause.  If the SQL AS clause was not specified, then the label is the
name of the column
reader – An object that contains the data to set the parameter value to.
length – the number of characters in the parameter data.
