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:
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 beAINSWORTH
rs.updateRow(); // updates the row in the data source
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 beAINSWORTH
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.

- if a database access error occurs or this method is called on a closed result setString getCursorName() throws SQLException
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.

Gets the value of the designated column in the current row of this ResultSet
object as an Object

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.

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()

- if the JDBC driver does not support this methodvoid refreshRow() throws SQLException
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.
