Class jdbcResultSet
- All Implemented Interfaces:
AutoCloseable
,ResultSet
,Wrapper
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, there is no way for the programmer to guarantee that they actually refer to the intended columns.
A set of updater methods were added to this interface in the JDBC 2.0 API (JavaTM 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 row 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 ResulSetMetaData
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. However, since 1.7.0, 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
invalid reference
Database
Server
,
WebServer
or in-process mode Database.
Including HSQLDB 1.7.2, there is no support for any of the methods
introduced in JDBC 2 relating to updateable result sets. These methods
include all updateXXX methods, as well as the insertRow()
,
updateRow()
, deleteRow()
, moveToInsertRow()
(and so on)
methods; invoking any such method throws an SQLException
stating that the operation is not supported.
JRE 1.1.x Notes:
In general, JDBC 2 support requires Java 1.2 and above, and JDBC 3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.
Since 1.7.0, it is possible to build the product so that
all JDBC 2 methods can be called while executing under the version 1.1.x
Java Runtime EnvironmentTM.
However, some of these method calls require int
values that
are defined only in the JDBC 2 or greater version of the
ResultSet
interface. For this reason, when the
product is compiled under JDK 1.1.x, these values are defined here, in this
class.
In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the
JDBC2-only ResultSet
values can be achieved by referring
to them in parameter specifications and return value comparisons,
respectively, as follows:
jdbcResultSet.FETCH_FORWARD jdbcResultSet.TYPE_FORWARD_ONLY jdbcResultSet.TYPE_SCROLL_INSENSITIVE jdbcResultSet.CONCUR_READ_ONLY // etc.However, please note that code written in such a manner will not be compatible for use with other JDBC 2 drivers, since they expect and use
ResultSet
, rather than jdbcResultSet
. Also
note, this feature is offered solely as a convenience to developers
who must work under JDK 1.1.x due to operating constraints, yet wish to
use some of the more advanced features available under the JDBC 2
specification.

Method Details
-
next
Moves the cursor down 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.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.- Specified by:
next
in interfaceResultSet
- Returns:
true
if the new current row is valid;false
if there are no more rows- Throws:
SQLException
- if a database access error occurs
-
close
Releases thisResultSet
object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.Note: A
ResultSet
object is automatically closed by theStatement
object that generated it when thatStatement
object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. AResultSet
object is also automatically closed when it is garbage collected.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs
-
wasNull
Reports whether the last column read had a value of SQLNULL
. Note that you must first call one of the getter methods on a column to try to read its value and then call the methodwasNull
to see if the value read was SQLNULL
.- Specified by:
wasNull
in interfaceResultSet
- Returns:
true
if the last column value read was SQLNULL
andfalse
otherwise- Throws:
SQLException
- if a database access error occurs
-

-
getAsciiStream
Retrieves the value of the designated column in the current row of thisResultSet
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 largeLONGVARCHAR 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 methodInputStream.available
is called whether there is data available or not.HSQLDB-Specific Information:
The limitation noted above does not apply to HSQLDB.
In 1.6.1 and previous, getAsciiStream was identical to getUnicodeStream and both simply returned a byte stream constructed from the raw
getBytes
representation. Starting with 1.7.0, this has been updated to comply with the java.sql specification. 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 JavaString
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 aregetString
,getUnicodeStream
(deprecated) and new to 1.7.0:getCharacterStream
(now prefered over the deprecated getUnicodeStream alternative).- Specified by:
getAsciiStream
in interfaceResultSet
- Parameters:
columnIndex
- the first column is 1, the second is 2, ...- Returns:
- a Java input stream that delivers the database column value
as a stream of one-byte ASCII characters;
if the value is SQL
NULL
, the value returned isnull
- Throws:
SQLException
- if a database access error occurs
-
getUnicodeStream
Deprecated.usegetCharacterStream
in place ofgetUnicodeStream
Retrieves the value of the designated column in the current row of thisResultSet
object as as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving largeLONGVARCHAR
values. The JDBC driver will do any necessary conversion from the database format into Unicode.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 methodInputStream.available
is called, whether there is data available or not.HSQLDB-Specific Information:
The limitation noted above does not apply to HSQLDB.
Up to and including 1.6.1, getUnicodeStream (and getAsciiStream) both simply returned a byte stream constructed from the raw

clearWarnings
in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs
-
getCursorName
Retrieves the name of the SQL cursor used by thisResultSet
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 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
ResultSet
object. The current row of aResultSet
object is also the current row of this SQL cursor.Note: If positioned update is not supported, a
SQLException
is thrown.HSQLDB-Specific Information:
Including 1.7.2, HSQLDB does not support this feature.
Calling this method always throws an
SQLException
, stating that the operation is not supported.- Specified by:
getCursorName
in interfaceResultSet
- Returns:
- the SQL name for this
ResultSet
object's cursor - Throws:
SQLException
- if a database access error occurs
-
getMetaData
Retrieves the number, types and properties of thisResultSet
object's columns.HSQLDB-Specific Information:
Example:
The following code fragment creates a

object rs, creates aResultSetMetaData
object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in aWHERE
clause.ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2"); ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
Warning:Including 1.7.1, HSQLDB did not generate accurate
ResultSetMetaData
. Below were the the most important methods to consider:- isAutoIncrement(int) always returned
false
- isCurrency(int) always returned
false
- isNullable(int) always returned
columnNullableUnknown
- getColumnDisplaySize(int) returned zero for all valid column numbers
- getSchemaName(int) always returned ""
- getPrecision(int) always returned zero
- getScale(int) always returned zero
- getCatalogName(int) always returned ""
Starting with 1.7.2, ResultSetMetaData has been split out into its own interface implemenation (jdbcResultSetMetaData), support has been improved considerably for a number of methods and behaviour has been altered slightly in many areas.- Specified by:

is the same as callingfirst()
. Callingabsolute(-1)
is the same as callinglast()
.- Specified by:
absolute
in interfaceResultSet

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.HSQLDB-Specific Information:
