public class jdbcResultSet
extends java.lang.Object
implements java.sql.ResultSet, java.sql.ResultSetMetaData

In HSQL Database Engine, the class jdbcResultSet implements both the ResultSet and ResultSetMetaData interfaces. To conform the JDBC standard, it is anyway required to call the 'getMetaData' function to get the ResultSetMetaData of the ResultSet. This is so because in other JDBC drivers the interfaces are not implemented in the same class.

ResultSetMetaData can be used to find out about the types and properties of the columns in a ResultSet.

A ResultSet provides access to a table of data. A ResultSet object is usually generated by executing a Statement.

A ResultSet 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.

The getXXX methods retrieve column values for the current row. You can retrieve values 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, ResultSet columns within each row should be read in left-to-right order and each column should be read only once.

For the getXXX methods, the JDBC driver attempts to convert the underlying data to the specified Java type and returns a suitable Java value. See the JDBC specification for allowable mappings from SQL types to Java types with the ResultSet.getXXX methods.

Column names used as input to getXXX methods are case insensitive. When performing a getXXX using a column name, if several columns have the same name, then 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. 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 ResultSet is automatically closed by the Statement that generated it when that Statement 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's columns are provided by the ResulSetMetaData object returned by the getMetaData method.

Method Detail

next

public boolean next()
             throws java.sql.SQLException
Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to 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. The ResultSet's warning chain is cleared when a new row is read.

Specified by:
next in interface java.sql.ResultSet
Returns:
true if the new current row is valid; false if there are no more rows

close

public void close()
Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Note: A ResultSet is automatically closed by the Statement that generated it when that Statement is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet is also automatically closed when it is garbage collected.

Specified by:
close in interface java.sql.ResultSet

wasNull

public boolean wasNull()
Reports whether the last column read had a value of SQL NULL. Note that you must first call getXXX on a column to try to read its value and then call wasNull() to see if the value read was SQL NULL.
Specified by:
wasNull in interface java.sql.ResultSet
Returns:
true if last column read was SQL NULL and false otherwise

getUnicodeStream

public java.io.InputStream getUnicodeStream(int column)
                                     throws java.sql.SQLException
Deprecated.  

Gets the value of a column in the current row as a stream of Unicode 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 Unicode. The byte format of the Unicode stream must Java UTF-8, as specified in the Java Virtual Machine Specification.

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 get method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.

Specified by:
getUnicodeStream in interface java.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 two-byte Unicode characters. If the value is SQL NULL then the result is null.

public java.sql.SQLWarning getWarnings()

The first warning reported by calls on this ResultSet is returned. Subsequent ResultSet warnings will be chained to this SQLWarning.

The warning chain is automatically cleared each time a new row is read.

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.

HSQL Database Engine never produces warnings and returns always null.

Specified by:
getWarnings in interface java.sql.ResultSet
Returns:
the first SQLWarning or null

clearWarnings

public void clearWarnings()
After this call getWarnings returns null until a new warning is reported for this ResultSet.
Specified by:
clearWarnings in interface java.sql.ResultSet

getCursorName

public java.lang.String getCursorName()
                               throws java.sql.SQLException
Gets the name of the SQL cursor used by this ResultSet.

In SQL, a result table is retrieved through a cursor that is named. The current row of a result 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 the 'for update' clause is omitted the positioned updates may fail.

JDBC supports this SQL feature by providing the name of the SQL cursor used by a ResultSet. The current row of a ResultSet is also the current row of this SQL cursor.

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

Specified by:
getCursorName in interface java.sql.ResultSet
Returns:
the ResultSet's SQL cursor name
Throws:
java.sql.SQLException - if a database access error occurs

getMetaData

Retrieves the number, types and properties of a ResultSet's columns.

HSQL Database Engine implements both the ResultSet and the ResultSetMetaData interface in the class jdbcResultSet, so this function will return the same Object. It is required to call this function to conform the JDBC standard. Other drivers have the ResultSetMetaData in a different class.

Specified by:
getMetaData in interface java.sql.ResultSet
Returns:
the description of a ResultSet's columns
Throws:
java.sql.SQLException - if a database access error occurs

getObject

public java.lang.Object getObject(java.lang.String columnName)
                           throws java.sql.SQLException

Gets the value of a column in the current row as a Java 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 spec.

This method may also be used to read datatabase-specific abstract data types. JDBC 2.0 In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types. When the 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:
getObject in interface java.sql.ResultSet
Parameters:
columnIndex - the first column is 1, the second is 2, ...
Returns:
a java.lang.Object holding the column value
Throws:
java.sql.SQLException - if a database access error occurs

getObject

public boolean isLast()
               throws java.sql.SQLException
JDBC 2.0

Indicates whether the cursor is on the last row of the result set. 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.

Specified by:
isLast in interface java.sql.ResultSet
Returns:
true if the cursor is on the last row, false otherwise.
Throws:
java.sql.SQLException - if a database access error occurs

beforeFirst

public void beforeFirst()
                 throws java.sql.SQLException
JDBC 2.0

public void afterLast()
               throws java.sql.SQLException
JDBC 2.0

Moves the cursor to the end of the result set, just after the last row. Has no effect if the result set contains no rows.

Specified by:
afterLast in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

first

public boolean first()
              throws java.sql.SQLException
JDBC 2.0

Moves the cursor to the first row in the result set.

Specified by:
first in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if there are no rows in the result set
Throws:
java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

last

public boolean last()
             throws java.sql.SQLException
JDBC 2.0

Moves the cursor to the last row in the result set.

Specified by:
last in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if there are no rows in the result set
Throws:
java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY.

getRow

public int getRow()
JDBC 2.0

Retrieves the current row number. The first row is number 1, the second number 2, and so on.

Specified by:
getRow in interface java.sql.ResultSet
Returns:
the current row number; 0 if there is no current row

absolute

public boolean absolute(int row)
                 throws java.sql.SQLException
JDBC 2.0

Moves the cursor to the given row number in the result set.

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 absolute(-1) positions the cursor on the last row, absolute(-2) indicates 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/after the first/last row, respectively.

Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

Specified by:
absolute in interface java.sql.ResultSet
Returns:
true if the cursor is on the result set; false otherwise
Throws:
java.sql.SQLException - if a database access error occurs or row is 0, or result set type is TYPE_FORWARD_ONLY.

relative

public boolean relative(int rows)
                 throws java.sql.SQLException
JDBC 2.0

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 relative(1) is different from calling next() because is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the result set.

Specified by:
relative in interface java.sql.ResultSet
Returns:
true if the cursor is on a row; false otherwise
Throws:
java.sql.SQLException - if a database access error occurs, there is no current row, or the result set type is TYPE_FORWARD_ONLY

previous

public boolean previous()
                 throws java.sql.SQLException
JDBC 2.0

Moves the cursor to the previous row in the result set.

Note: previous() is not the same as relative(-1) because it makes sense to callprevious() when there is no current row.

Specified by:
previous in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if it is off the result set
Throws:
java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

                  throws java.sql.SQLException
JDBC 2.0 Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this result set. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by the statement that created the result set. The fetch size may be changed at any time.
Specified by:
setFetchSize in interface java.sql.ResultSet
Parameters:
rows - the number of rows to fetch
Throws:
java.sql.SQLException - if a database access error occurs or the condition 0 <= rows <= this.getMaxRows() is not satisfied.

See Also:
DatabaseMetaData.insertsAreDetected(int)

rowDeleted

public boolean rowDeleted()
JDBC 2.0 Indicates 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 the result set can detect deletions.
Specified by:
rowDeleted in interface java.sql.ResultSet
Returns:
true if a row was deleted and deletions are detected

insertRow

public void insertRow()
               throws java.sql.SQLException
JDBC 2.0 Inserts the contents of the insert row into the result set and the database. Must be on the insert row when this method is called.
Specified by:
insertRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs, if called when not on the insert row, or if not all of non-nullable columns in the insert row have been given a value

updateRow

public void updateRow()
               throws java.sql.SQLException
JDBC 2.0 Updates the underlying database with the new contents of the current row. Cannot be called when on the insert row.
Specified by:
updateRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or if called when on the insert row

deleteRow

public void deleteRow()
               throws java.sql.SQLException
JDBC 2.0 Deletes the current row from the result set and the underlying database. Cannot be called when on the insert row.
Specified by:
deleteRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or if called when on the insert row.

refreshRow

public void refreshRow()
                throws java.sql.SQLException
JDBC 2.0 Refreshes the current row with its most recent value in the database. Cannot be called when 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 updateXXX, but before calling updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.
Specified by:
refreshRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or if called when on the insert row

cancelRowUpdates

public void cancelRowUpdates()
                      throws java.sql.SQLException

Specified by:
cancelRowUpdates in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or if called when on the insert row

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException
JDBC 2.0 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 updateXXX methods prior to inserting the row into the result set. Only the updateXXX, getXXX, 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. The method updateXXX must be called before a getXXX method can be called on a column value.
Specified by:
moveToInsertRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or the result set is not updatable

moveToCurrentRow

public void moveToCurrentRow()
                      throws java.sql.SQLException
JDBC 2.0 Moves the cursor to the remembered cursor position, usually the current row. This method has no effect if the cursor is not on the insert row.
Specified by:
moveToCurrentRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs or the result set is not updatable

getStatement

public java.sql.Statement getStatement()
                                throws java.sql.SQLException
