public interface ResultSet extends Wrapper, AutoCloseable
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 updatableThe
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 theNAME
column in the fifth row of theResultSet
objectrs
and then uses the methodupdateRow
to update the data source table from whichrs
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 beAINSWORTH
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 intors
and into the data source table using the methodinsertRow
.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.

boolean next()
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.
- Returns:
true
if the new current row is valid;false
if there are no more rows- Throws:
SQLException
- if a database access error occurs or this method is called on a closed result set
void close()

,
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.
When a ResultSet
is closed, any ResultSetMetaData
instances that were created by calling the getMetaData
method remain accessible.
Note: A ResultSet
object
is automatically closed by the
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.
Calling the method close
on a ResultSet
object that is already closed is a no-op.

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.
- Returns:
- the first
SQLWarning
object reported ornull
if there are none - Throws:
SQLException
- if a database access error occurs or this method is called on a closed result set
void clearWarnings()
ResultSet

returns null
until a new warning is
reported for this ResultSet
object.- Throws:
SQLException
- if a database access error occurs or this method is called on a closed result set
String getCursorName()
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.
- Returns:
- the SQL name for this
ResultSet
object's cursor - Throws:
SQLException
- if a database access error occurs or this method is called on a closed result setSQLFeatureNotSupportedException
- if the JDBC driver does not support this method

ResultSet
object's columns.- Returns:
- the description of this
ResultSet
object's columns - Throws:
SQLException
- if a database access error occurs or this method is called on a closed result set
Object getObject(int columnIndex)
Gets the value of the designated column in the current row
of this ResultSet
object as
an Object
in the Java programming language.
This method will return the value of the given column as a
Java object. The type of the Java object will be the default
Java object type corresponding to the column's SQL type,
following the mapping for built-in types specified in the JDBC
specification. If the value is an SQL NULL
,
the driver returns a Java null
.
This method may also be used to read database-specific
abstract data types.
In the JDBC 2.0 API, the behavior of method
getObject
is extended to materialize
data of SQL user-defined types.
If Connection.getTypeMap
does not throw a
SQLFeatureNotSupportedException
,
then when a column contains a structured or distinct value,
the behavior of this method is as
if it were a call to: getObject(columnIndex,
this.getStatement().getConnection().getTypeMap())
.
If Connection.getTypeMap
does throw a
SQLFeatureNotSupportedException
,

- Parameters:
columnIndex
- the first column is 1, the second is 2, ...- Returns:

Object getObject(String columnLabel)
Gets the value of the designated column in the current row
of this ResultSet
object as
an Object
in the Java programming language.
This method will return the value of the given column as a
Java object. The type of the Java object will be the default
Java object type corresponding to the column's SQL type,
following the mapping for built-in types specified in the JDBC
specification. If the value is an SQL NULL
,
the driver returns a Java null
.
This method may also be used to read database-specific abstract data types.
In the JDBC 2.0 API, the behavior of the method
getObject
is extended to materialize
data of SQL user-defined types. When a column contains
a structured or distinct value, the behavior of this method is as
if it were a call to: getObject(columnIndex,
this.getStatement().getConnection().getTypeMap())
.

boolean absolute(int row)
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.
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 the last row.
Note: Calling absolute(1)
is the same
as calling first()
. Calling absolute(-1)
is the same as calling last()
.
- Parameters:
row
- the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set- Returns:
true
if the cursor is moved to a position in thisResultSet
object;false

to calling the method previous()
.
- Parameters:
rows
- anint
specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward- Returns:
true
if the cursor is on a row;false
otherwise- Throws:
SQLException

If an input stream is open for the current row, a call to the method
previous
will implicitly close it. A ResultSet
object's warning change is cleared when a new row is read.
- Returns:
true
if the cursor is now positioned on a valid row;false
if the cursor is positioned before the first row- Throws:
SQLException
- if a database access error occurs; this method is called on a closed result set or the result set type isTYPE_FORWARD_ONLY

void refreshRow()
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.
- Throws:
SQLException
- if a database access error occurs; this method is called on a closed result set; the result set type isTYPE_FORWARD_ONLY
