public class JDBCResultSet extends java.lang.Object implements java.sql.ResultSetA table of data representing a database result set, which is usually generated by executing a statement that queries the database.A
ResultSetobject maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. Thenextmethod moves the cursor to the next row, and because it returnsfalsewhen there are no more rows in theResultSetobject, it can be used in awhileloop to iterate through the result set.A default
ResultSetobject 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 produceResultSetobjects that are scrollable and/or updatable. The following code fragment, in whichconis a validConnectionobject, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. SeeResultSetfields 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 updatableTheResultSetinterface 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
ResultSetgetter 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
ResultSetobject, 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 theNAMEcolumn in the fifth row of theResultSetobjectrsand then uses the methodupdateRowto update the data source table from whichrswas derived.rs.absolute(5); // moves the cursor to the fifth row of rs rs.updateString("NAME", "AINSWORTH"); // updates the //NAMEcolumn of row 5 to beAINSWORTHrs.updateRow(); // updates the row in the data source - to insert column values into the insert row. An updatable
ResultSetobject 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 intorsand 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 beAINSWORTHrs.updateInt(2,35); // updates the second column to be35rs.updateBoolean(3, true); // updates the third column totruers.insertRow(); rs.moveToCurrentRow();
A
ResultSetobject is automatically closed when theStatementobject 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
ResultSetobject's columns are provided by theResultSetMetaDataobject returned by theResultSet.getMetaDatamethod.HSQLDB-Specific Information:
AResultSetobject 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. If a statement is created with:Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
then theResultSetobjects 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);
A non-updatable HSQLDBResultSetobject stays open if it is not explicitly closed, even after its connection is closed. A connection opened with the property settingclose_result=truecloses any remaining open results when the connection is closed.From HSQLDB 2.0, there is full support for updatable result sets. Supported methods include all updateXXX methods for the supported types, as well as the
insertRow(),updateRow(),deleteRow(),moveToInsertRow()methods.The Statement must be created with ResultSet.CONCUR_UPDATABLE instead of CONCUR_READ_ONLY.
Updatability of a result set follows the SQL standards. Some or all columns of an updatable result set can be updated. The current row in such result sets can be deleted using the
deleteRow()method. Some updatable result set can also be inserted into and supportmoveToInsertRow().A result set is updatable if the SELECT statement is updatable. This includes SELECT from TABLE and updatable VIEW objects. An updatable SELECT statement has a single underlying table or view. HSQLDB supports both scrollable and forward-only result sets for updatability.
-- In the SELECT below, columns A and B are updatable, any row can be -- deleted, but it is not insertable-into as column C is not directly from -- the table. SELECT A, B, A + B AS C FROM T WHERE ... -- The SELECT below can be insertable-into so long as other columns of the -- table that do not appear in the SELECT list have a default value. SELECT A, B FROM T WHERE ...
From version 2.7.4, support for updatable result sets is extended to make updates and deletes visible. This feature is useful with scrollable result sets. After callingupdateRow, therowUpdatedmethod now returnstrueon an updated row. After callingdeleteRow, therowDeletedmethod now returnstrueon a deleted row. Calling agetXXXmethod returns the updated values for updated rows andnullfor deleted rows. (fredt@users)

next
public boolean next() throws java.sql.SQLExceptionMoves the cursor forward one row from its current position. AResultSetcursor is initially positioned before the first row; the first call to the methodnextmakes the first row the current row; the second call makes the second row the current row, and so on.When a call to the
nextmethod returnsfalse, the cursor is positioned after the last row. Any invocation of aResultSetmethod which requires a current row will result in aSQLExceptionbeing thrown. If the result set type isTYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will returnfalseor throw anSQLExceptionon a subsequent call tonext.If an input stream is open for the current row, a call to the method
nextwill implicitly close it. AResultSetobject's warning chain is cleared when a new row is read.- Specified by:
nextin interfacejava.sql.ResultSet- Returns:
trueif the new current row is valid;falseif there are no more rows- Throws:
java.sql.SQLException- if a database access error occurs or this method is called on a closed result set
-
close
public void close() throws java.sql.SQLExceptionReleases thisResultSetobject's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.The closing of a
ResultSetobject does not close theBlob,CloborNClobobjects created by theResultSet.Blob,CloborNClobobjects remain valid for at least the duration of the transaction in which they are created, unless theirfreemethod is invoked.When a
ResultSetis closed, anyResultSetMetaDatainstances that were created by calling thegetMetaDatamethod remain accessible.Note: A
ResultSetobject is automatically closed by theStatementobject that generated it when thatStatementobject is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.Calling the method
closeon aResultSetobject that is already closed is a no-op.- Specified by:

The next call to a getter method implicitly closes the stream. Also, a stream may return
0when the methodInputStream.availableis called whether there is data available or not.HSQLDB-Specific Information:
The limitation noted above does not apply to HSQLDB.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 Java
Stringrepresentation 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
CHARand 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 preferred over the deprecated getUnicodeStream alternative).- Specified by:

getUnicodeStreamin interfacejava.sql.ResultSet- Parameters:
columnLabel- the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column- Returns:
- a Java input stream that delivers the database column value
as a stream of two-byte Unicode characters.
If the value is SQL
NULL, the value returned isnull. - Throws:
java.sql.SQLException- if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result setjava.sql.SQLFeatureNotSupportedException- if the JDBC driver does not support this method
-
getBinaryStream
public java.io.InputStream getBinaryStream(java.lang.String columnLabel) throws java.sql.SQLExceptionRetrieves the value of the designated column in the current row of thisResultSetobject as a stream of uninterpretedbytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving largeLONGVARBINARYvalues.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
0when the methodavailableis called whether there is data available or not.- Specified by:
getBinaryStreamin interfacejava.sql.ResultSet- Parameters:
columnLabel- the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column- Returns:
- a Java input stream that delivers the database column value
as a stream of uninterpreted bytes;
if the value is SQL
NULL, the result isnull - Throws:
java.sql.SQLException- if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set
-
getWarnings
public java.sql.SQLWarning getWarnings() throws java.sql.SQLExceptionRetrieves the first warning reported by calls on thisResultSetobject. Subsequent warnings on thisResultSetobject will be chained to theSQLWarningobject that this method returns.The warning chain is automatically cleared each time a new row is read. This method may not be called on a
ResultSetobject that has been closed; doing so will cause anSQLExceptionto be thrown.Note: This warning chain only covers warnings caused by
ResultSetmethods. Any warning caused byStatementmethods (such as reading OUT parameters) will be chained on theStatementobject.HSQLDB-Specific Information:
HSQLDB does not produceSQLWarningobjects on any ResultSet object warning chain; this method always returnsnull.- Specified by:
getWarningsin interfacejava.sql.ResultSet- Returns:
- the first
SQLWarningobject reported ornullif there are none - Throws:
java.sql.SQLException- if a database access error occurs or this method is called on a closed result set
-

HSQLDB does not produceSQLWarningobjects on any ResultSet object warning chain; calls to this method are ignored.- Specified by:
clearWarningsin interfacejava.sql.ResultSet- Throws:
java.sql.SQLException- if a database access error occurs or this method is called on a closed result set
-
getCursorName
public java.lang.String getCursorName() throws java.sql.SQLExceptionRetrieves the name of the SQL cursor used by thisResultSetobject.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 ensure that the cursor has the proper isolation level to support update, the cursor's
SELECTstatement should be of the formSELECT FOR UPDATE. IfFOR UPDATEis omitted, the positioned updates may fail.The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a
ResultSetobject. The current row of aResultSetobject is also the current row of this SQL cursor.HSQLDB-Specific Information:
HSQLDB supports this feature when the cursor has a name.- Specified by:
getCursorNamein interfacejava.sql.ResultSet- Returns:
- the SQL name for this
ResultSetobject's cursor - Throws:
java.sql.SQLException- if a database access error occurs or this method is called on a closed result setjava.sql.SQLFeatureNotSupportedException- if the JDBC driver does not support this method
-
getMetaData
public java.sql.ResultSetMetaData getMetaData() throws java.sql.SQLExceptionRetrieves the number, types and properties of thisResultSetobject's columns.HSQLDB-Specific Information:
Example:The following code fragment creates a
ResultSetobject rs, creates aResultSetMetaDataobject rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in aWHEREclause.ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2"); ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
Changes:With version 2.0, the engine's SQL implementation has been completely rewritten. Changes to this class and the implementation of ResultSetMetaData reflect the engine's new capabilities and provide more accurate information.
changes to consider:
- isAutoIncrement(int) always returned
false - isNullable(int) returns the nullability of a real table or view
column in the ResultSet and returns
columnNoNullsfor non-base-column ResultSet columns (columns of the ResultSet that are based on expressions or aggregates). - getColumnDisplaySize(int) returns correct results even for expression columns.
- getPrecision(int) returns the correct precision even for expression columns.
- getScale(int) returns the correct precision even for expression columns.
- getCatalogName(int) returns the catalog name of the database.
- Specified by:
getMetaDatain interfacejava.sql.ResultSet- Returns:
- the description of this
ResultSetobject's columns - Throws:
java.sql.SQLException- if a database access error occurs or this method is called on a closed result set
- isAutoIncrement(int) always returned
-
getObject
public java.lang.Object getObject(int columnIndex) throws java.sql.SQLExceptionGets the value of the designated column in the current row of this
ResultSetobject as anObjectin 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 Javanull.This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method
getObjectis extended to materialize data of SQL user-defined types.If
Connection.getTypeMapdoes 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.getTypeMapdoes 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.- Specified by:
getObjectin interfacejava.sql.ResultSet- Parameters:
columnIndex- the first column is 1, the second is 2, ...- Returns:
- a
java.lang.Objectholding the column value - Throws:
java.sql.SQLException- if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
-
getObject
public java.lang.Object getObject(java.lang.String columnLabel) throws java.sql.SQLExceptionGets the value of the designated column in the current row of this
ResultSetobject as anObjectin 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 Javanull.This method may also be used to read database-specific abstract data types.
In the JDBC 2.0 API, the behavior of the method
getObjectis extended to materialize data of SQL user-defined types. 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()).- Specified by:
getObjectin interfacejava.sql.ResultSet- Parameters:
columnLabel- the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column- Returns:
- a
java.lang.Objectholding the column value - Throws:

findColumn
public int findColumn(java.lang.String columnLabel) throws java.sql.SQLExceptionMaps the givenResultSetcolumn label to itsResultSetcolumn index.HSQLDB-Specific Information:
Starting with 1.9.x, HSQLDB does an exhaustive search, backed by a cache lookup (to improve performance for subsequent invocations with a given input).Upon careful investigation of the JDBC specification and the behaviour of existing JDBC drivers, there is actually nothing preventing the findColumn method from doing an exhaustive search, as long as it conforms to the following rules (which describe the new implementation):
- the entire search is case insensitive
- each search iteration occurs from leftmost to rightmost column, returning the first match encountered
- the first pass matches only bare column labels
- the second pass matches only simple column names
- further passes conform to the identifier qualification and identifier quoting rules of the engine
Instead:
- a third pass matches simple table-dot-column qualified names
- a fourth pass matches simple schema-dot-table-dot-column qualified column names
- Specified by:
findColumnin interfacejava.sql.ResultSet- Parameters:
columnLabel- the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column- Returns:

absolute
public boolean absolute(int row) throws java.sql.SQLExceptionMoves the cursor to the given row number in thisResultSetobject.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.

Attempting to move beyond the first/last row in the result set positions the cursor before/after 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().- Specified by:
relativein interfacejava.sql.ResultSet- Parameters:
rows- anintspecifying 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:
trueif the cursor is on a row;falseotherwise- Throws:

public void updateRow() throws java.sql.SQLExceptionUpdates the underlying database with the new contents of the current row of thisResultSetobject. This method cannot be called when the cursor is on the insert row.HSQLDB-Specific Information:
HSQLDB supports this feature.After updating any values in the current row, it is not possible to move the cursor position without calling this method, or alternatively calling cancelRowUpdates() to abandon the row update.
After calling this method, the
getXXXmethods return the updated values for the updated row.- Specified by:
updateRowin interfacejava.sql.ResultSet- Throws:
java.sql.SQLException- if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY; this method is called on a closed result set or if this method is called when the cursor is on the insert rowjava.sql.SQLFeatureNotSupportedException- if the JDBC driver does not support this method- Since:

refreshRow
public void refreshRow() throws java.sql.SQLExceptionRefreshes 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
refreshRowmethod 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 callrefreshRowwhen 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
refreshRowis called after calling an updater method, but before calling the methodupdateRow, then the updates made to the row are lost. Calling the methodrefreshRowfrequently will likely slow performance.HSQLDB-Specific Information:
HSQLDB supports this feature.- Specified by:
refreshRowin interfacejava.sql.ResultSet- Throws:
java.sql.SQLException- if a database access error occurs; this method is called on a closed result set; the result set type isTYPE_FORWARD_ONLYor if this method is called when the cursor is on the insert rowjava.sql.SQLFeatureNotSupportedException- if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency.- Since:

moveToInsertRow
public void moveToInsertRow() throws java.sql.SQLExceptionMoves 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, andinsertRowmethods 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.HSQLDB-Specific Information:
