Class jdbcResultSet

Implemented Interfaces:
ResultSet

public class jdbcResultSet
extends java.lang.Object
implements ResultSet

<!-- start generic documentation --> 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 updatable

 
The 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:

  1. 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 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 be AINSWORTH
     rs.updateRow(); // updates the row in the data source
    
     
  2. 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 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 be AINSWORTH
     rs.updateInt(2,35); // updates the second column to be 35
     rs.updateBoolean(3, true); // updates the third row 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 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 Database from which it came. That is, they persist whether originating from a 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

absolute

public boolean absolute(int row)
            throws SQLException
<!-- start generic documentation --> 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.

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().

<!-- end generic documentation -->

Parameters:
row - the number of the row to which the cursor should move. 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 if the cursor is on the result set; false otherwise

<!-- start generic documentation --> Retrieves the value of the designated column in the current row of this ResultSet 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 large LONGVARCHAR 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 method available is called whether there is data available or not.

<!-- end generic documentation -->

Parameters:
columnName - the SQL name of the column
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 is null.

getAsciiStream

public java.io.InputStream getAsciiStream(int columnIndex)
            throws SQLException
<!-- start generic documentation --> Retrieves the value of the designated column in the current row of this ResultSet 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 large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

<!-- end generic documentation --> <!-- start release-specific documentation -->

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 Java String 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 are getString, getUnicodeStream (deprecated) and new to 1.7.0: getCharacterStream (now prefered over the deprecated getUnicodeStream alternative).

<!-- end release-specific documentation -->
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 is null

<!-- start generic documentation --> 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.

Note: If positioned update is not supported, a SQLException is thrown.

            throws SQLException
<!-- start generic documentation --> Retrieves the number, types and properties of this ResultSet object's columns.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

Example:

The following code fragment creates a ResultSet object rs, creates a ResultSetMetaData object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in a WHERE 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:

  1. isAutoIncrement(int) always returned false
  2. isCurrency(int) always returned false
  3. isNullable(int) always returned columnNullableUnknown
  4. getColumnDisplaySize(int) returned zero for all valid column numbers
  5. getSchemaName(int) always returned ""
  6. getPrecision(int) always returned zero
  7. getScale(int) always returned zero
  8. 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.

If the value is an SQL NULL, the driver returns a Java null.

This method may also be used to read datatabase-specific abstract data types.

In the JDBC 2.0 API, the behavior of the method getObject is 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()).

Parameters:
columnName - the SQL name of the column
Returns:
a java.lang.Object holding the column value

getUnicodeStream

public java.io.InputStream getUnicodeStream(String columnName)
            throws SQLException

Deprecated. use getCharacterStream instead

<!-- start generic documentation --> Retrieves the value of the designated column in the current row of this ResultSet object 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 large LONGVARCHAR values. The JDBC technology-enabled 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 method InputStream.available is called, whether there is data available or not.

<!-- end generic documentation -->

Parameters:
columnName - the SQL 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 is null.

getUnicodeStream

public java.io.InputStream getUnicodeStream(int columnIndex)
            throws SQLException

Deprecated. use getCharacterStream in place of getUnicodeStream

<!-- start generic documentation --> Retrieves the value of the designated column in the current row of this ResultSet 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 large LONGVARCHARvalues. 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 method InputStream.available is called, whether there is data available or not.

<!-- end generic documentation --> <!-- start release-specific documentation -->

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 Java String 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.

<!-- end release-specific documentation -->
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 two-byte Unicode characters; if the value is SQL NULL, the value returned is null

getWarnings

public SQLWarning getWarnings()
            throws SQLException
<!-- start generic documentation --> Retrieves the first warning reported by calls on this ResultSet object. Subsequent warnings on this ResultSet object will be chained to the SQLWarning object 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 ResultSet object that has been closed; doing so will cause an SQLException to be thrown.

Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

Up to and including 1.7.1, HSQLDB does not produce SQLWarning objects. This method always returns null.

<!-- end release-specific documentation -->
Returns:
the first SQLWarning object reported or null if there are none

Up to and including 1.7.1, HSQLDB always returns null.


insertRow

public void insertRow()

isLast

public boolean isLast()
            throws SQLException
<!-- start generic documentation --> Retrieves whether the cursor is on the last row of this ResultSet object. Note: Calling the method isLast may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

Including 1.7.2, this method is not terribly expensive; the entire result is fetched internally before this object is returned to a caller.

<!-- end release-specific documentation -->
Returns:
true if the cursor is on the last row; false otherwise
Since:
JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

last

public boolean last()
            throws SQLException

moveToInsertRow

public void moveToInsertRow()
            throws SQLException
<!-- start generic documentation --> Moves 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, and insertRow methods 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 calling insertRow. An updater method must be called before a getter method can be called on a column value.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

Including 1.7.2, HSQLDB does not support updateable result sets.

This method always throws an SQLException stating that the operation is not supported.

Since:
JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

next

public boolean next()
            throws SQLException
<!-- start generic documentation --> Moves the cursor down 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.

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.

<!-- end generic documentation -->

Returns:
true if the new current row is valid; false if there are no more rows

previous

public boolean previous()
            throws SQLException
<!-- start generic documentation --> Moves the cursor to the previous row in this ResultSet object.

<!-- end generic documentation -->

Returns:
true if the cursor is on a valid row; false if it is off the result set
Since:
JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

refreshRow

public void refreshRow()
            throws SQLException
<!-- start generic documentation --> 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.

<!-- end generic documentation --> <!-- start release-specific documentation -->

Since:
JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

relative

public boolean relative(int rows)
            throws SQLException
<!-- start generic documentation --> 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().

<!-- end generic documentation -->

Parameters:
rows - an int 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 otherwise
Since:
JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

rowDeleted

public boolean rowDeleted()
            throws SQLException
<!-- start generic documentation --> Retrieves whether a row has been deleted. A deleted row may leave a visible "hole" in a result set. This method can be used to detect holes in a result set. The value returned depends on whether or not this ResultSet object can detect deletions.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

            throws SQLException
<!-- start generic documentation --> Gives a hint as to the direction in which the rows in this ResultSet object will be processed. The initial value is determined by the Statement object that produced this ResultSet object. The fetch direction may be changed at any time.

<!-- end generic documentation --> <!-- start release-specific documentation -->

HSQLDB-Specific Information:

Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method does nothing. However, as mandated by the JDBC standard, an SQLException is thrown if the result set type is TYPE_FORWARD_ONLY and a fetch direction other than FETCH_FORWARD is requested.
