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.

Method Details
-
next
Moves the cursor forward one row from its current position. AResultSet
cursor is initially positioned before the first row; the first call to the methodnext
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 returnsfalse
, the cursor is positioned after the last row. Any invocation of aResultSet
method which requires a current row will result in aSQLException
being thrown. If the result set type isTYPE_FORWARD_ONLY
, it is vendor specified whether their JDBC driver implementation will returnfalse
or throw anSQLException
on a subsequent call tonext
.If an input stream is open for the current row, a call to the method
next
will implicitly close it. AResultSet
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
-
close
Releases thisResultSet
object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.The closing of a
ResultSet
object does not close theBlob

SELECT
statement should be of the formSELECT FOR UPDATE
. IfFOR 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

If the value is an SQL
NULL
, the driver returns a Javanull
.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 aSQLFeatureNotSupportedException
, 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())
. IfConnection.getTypeMap
does throw aSQLFeatureNotSupportedException
, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.- Parameters:
columnIndex
- the first column is 1, the second is 2, ...- Returns:
- a
java.lang.Object
holding the column value - Throws:
SQLException
- if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set

getRow
Retrieves the current row number. The first row is number 1, the second number 2, and so on.Note:Support for the
getRow
method is optional forResultSet
s with a result set type ofTYPE_FORWARD_ONLY
- Returns:
- the current row number;
0
if there is no current row - 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- Since:
- 1.2
-
absolute
Moves the cursor to the given row number in thisResultSet
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 methodabsolute(-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 callingfirst()
. Callingabsolute(-1)
is the same as callinglast()
.- 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
if the cursor is before the first row or after the last 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
SQLFeatureNotSupportedException
- if the JDBC driver does not support this method- Since:
- 1.2
-
relative
Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Callingrelative(0)
is valid, but does not change the cursor position.Note: Calling the method
relative(1)
is identical to calling the methodnext()
and calling the methodrelative(-1)
is identical to calling the methodprevious()
.- 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 a database access error occurs; this method is called on a closed result set or the result set type isTYPE_FORWARD_ONLY
SQLFeatureNotSupportedException
- if the JDBC driver does not support this method- Since:
- 1.2
-
previous
Moves the cursor to the previous row in thisResultSet
object.When a call to the
previous
method returnsfalse
, the cursor is positioned before the first row. Any invocation of aResultSet
method which requires a current row will result in aSQLException
being thrown.If an input stream is open for the current row, a call to the method
previous
will implicitly close it. AResultSet
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

refreshRow
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 callrefreshRow
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 methodupdateRow
, then the updates made to the row are lost. Calling the methodrefreshRow
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

or if this method is called when the cursor is on the insert rowSQLFeatureNotSupportedException
- if the JDBC driver does not support this method- Since:
- 1.2
-
moveToInsertRow
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, andinsertRow
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 callinginsertRow
. An updater method must be called before a getter method can be called on a column value.- Throws:

The updater methods do not update the underlying database; instead the
updateRow
orinsertRow
methods are called to update the database.Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of
updateBlob
which takes a length parameter.- Parameters:
columnIndex
- the first column is 1, the second is 2, ...inputStream
- An object that contains the data to set the parameter value to.- Throws:
SQLException
- if the columnIndex is not valid; if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY
or this method is called on a closed result setSQLFeatureNotSupportedException
