public interface ResultSet extends Wrapper, AutoCloseable
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 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 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 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 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.

Methods
next
boolean next() throws SQLException
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.
- 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
void close() throws SQLException
Releases this ResultSet
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 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.
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.
- Specified by:
-
close
in interfaceAutoCloseable
- Throws:
-
SQLException
- if a database access error occurs
wasNull
boolean wasNull() throws SQLException
Reports whether the last column read had a value of SQL NULL
. Note that you must first call one of the getter methods on a column to try to read its value and then call the method wasNull
to see if the value read was SQL NULL
.
- Returns:
-
true
if the last column value read was SQLNULL
andfalse
otherwise - Throws:
-
SQLException
- if a database access error occurs or this method is called on a closed result set
getString
String getString(int columnIndex) throws SQLException
Retrieves the value of the designated column in the current row of this ResultSet
object as a String
in the Java programming language.
- Parameters:
-
columnIndex
- the first column is 1, the second is 2, ... - Returns:
- the column value; if the value is SQL
NULL
, the value returned isnull
- Throws:
-
SQLException
- if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
getBoolean
boolean getBoolean(int columnIndex) throws SQLException
Retrieves the value of the designated column in the current row of this ResultSet
object as a boolean
in the Java programming language.
If the designated column has a datatype of CHAR or VARCHAR and contains a "0" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT and contains a 0, a value of false
is returned. If the designated column has a datatype of CHAR or VARCHAR and contains a "1" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT and contains a 1, a value of true
is returned.
- Parameters:

getCursorName
String getCursorName() throws SQLException
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.
- Returns:
- the SQL name for this
ResultSet
object's cursor - Throws:
-
SQLException

getObject
Object getObject(int columnIndex) throws SQLException
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
, 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

absolute
boolean absolute(int row) throws SQLException
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.
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

relative
boolean relative(int rows) throws SQLException
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. Calling relative(0)
is valid, but does not change the cursor position.
Note: Calling the method relative(1)
is identical to calling the method next()
and calling the method relative(-1)
is identical 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

method which requires a current row will result in a SQLException
being thrown.
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

refreshRow
void refreshRow() throws SQLException
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.
- Throws:
-
SQLException

void updateClob(int columnIndex, Reader reader, long length) throws SQLException
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 JDBC driver will do any necessary conversion from UNICODE to the database char format.
