public class jdbcResultSet extends java.lang.Object implements java.sql.ResultSet
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. Thenext
method moves the cursor to the next row, and because it returnsfalse
when there are no more rows in theResultSet
object, it can be used in awhile
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 produceResultSet
objects that are scrollable and/or updatable. The following code fragment, in whichcon
is a validConnection
object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. SeeResultSet
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 updatable
TheResultSet
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 theStatement
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 theResulSetMetaData
object returned by theResultSet.getMetaData
method.HSQLDB-Specific Information:
A
ResultSet
object generated by HSQLDB is by default ofResultSet.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 theResultSet
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 HSQLDBResultSet
object persists, even after its connection is closed. This is regardless of the operational mode of theDatabase
from which it came. That is, they persist whether originating from aServer
,WebServer
or in-process modeDatabase.
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 anSQLException
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 theResultSet
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 useResultSet
, rather thanjdbcResultSet
. 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.(fredt@users)

next
public boolean next() throws java.sql.SQLException
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

getAsciiStream
public java.io.InputStream getAsciiStream(int columnIndex) throws java.sql.SQLException
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 interfacejava.sql.ResultSet
- 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:
java.sql.SQLException
- if a database access error occurs
-
getUnicodeStream
public java.io.InputStream getUnicodeStream(int columnIndex) throws java.sql.SQLException
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
getBytes
representation. Starting with 1.7.0, this has been corrected 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 Java Strings. 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 bytes from the value's String representation, with high-byte first.- Specified by:
getUnicodeStream
in interfacejava.sql.ResultSet
- Parameters:
columnIndex
- the first column is 1, the second is 2, ...- Returns:
- a Java input stream that delivers the database column value

0
when the methodInputStream.available
is called whether there is data available or not.- Specified by:
getBinaryStream
in interfacejava.sql.ResultSet
- Parameters:
columnIndex

getCursorName
public java.lang.String getCursorName() throws java.sql.SQLException
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:
