Class DriverResultSet

java.lang.Object
  org.objectweb.cjdbc.driver.DriverResultSet

All Implemented Interfaces:: java.lang.Cloneable, java.sql.ResultSet, java.io.Serializable

public class DriverResultSet
extends java.lang.Object
implements java.sql.ResultSet, java.io.Serializable, java.lang.Cloneable

A ResultSet provides access to a table of data generated by executing a Statement. The table rows are retrieved in sequence. Within a row its column values can be accessed in any order.

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 either using the index number of the column, or by using 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 insenstive. 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 were used there is no way for the programmer to guarentee 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 is 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 ResultSetMetaData object returned by the getMetaData method.

Parameters:: fields - an array of Field objects (basically, the ResultSet meta data); resultData - array of the actual data (data[row][column]); crsHasMoreData - true if remote ControllerResultSet has more data to fetch; cursorName - cursor name for a streamable ResultSet

Method Detail

public boolean next()
             throws java.sql.SQLException

A ResultSet is initially positioned before its first row, the first call to next makes the first row the current row; the second call makes the second row the current row, etc.

If an input stream from the previous row is open, it is implicitly closed. 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 is valid; false if there are no more rows
Throws:: java.sql.SQLException - if a database access error occurs

public boolean prev()
             throws java.sql.SQLException

The prev method is not part of JDBC, but because of the architecture of this driver it is possible to move both forward and backward within the result set.

If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read

Returns:: true if the new current is valid; false if there are no more rows
Throws:: java.sql.SQLException - if a database access error occurs

Throws:: java.sql.SQLException - if a database-access error occurs.

isLast

public boolean isLast()
               throws java.sql.SQLException

JDBC 2.0

Determine if the cursor is on the last row of the result set. Note: Calling isLast() may be expensive since 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 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

Moves to the front of the result set, just before the first row. Has no effect if the result set contains no rows.

Specified by:: beforeFirst in interface java.sql.ResultSet

afterLast

public void afterLast()
               throws java.sql.SQLException

JDBC 2.0

Moves 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 result set type is TYPE_FORWARD_ONLY.

first

public boolean first()
              throws java.sql.SQLException

JDBC 2.0

Moves to the first row in the result set.

Specified by:: first in interface java.sql.ResultSet

Returns:: true if on a valid row, false if no rows in the result set.
Throws:: java.sql.SQLException - if a database-access error occurs, or result set type is TYPE_FORWARD_ONLY.

last

public boolean last()
             throws java.sql.SQLException

JDBC 2.0

Moves to the last row in the result set.

Specified by:: last in interface java.sql.ResultSet

Returns:: true if on a valid row, false if no rows in the result set.
Throws:: java.sql.SQLException - if a database-access error occurs, or result set type is TYPE_FORWARD_ONLY.

getRow

public int getRow()
           throws java.sql.SQLException

JDBC 2.0

Determine the current row number. The first row is number 1, the second number 2, etc.

Specified by:: getRow in interface java.sql.ResultSet

Returns:: the current row number, else return 0 if there is no current row
Throws:: java.sql.SQLException - if a database-access error occurs.

absolute

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

JDBC 2.0

Move to an absolute row number in the result set.

If row is positive, moves to an absolute row with respect to the beginning of the result set. The first row is row 1, the second is row 2, etc.

If row is negative, moves to an absolute row position with respect to the end of result set. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.

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

Parameters:: row - the row to move to
Returns:: true if on the result set, false if off.
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 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 than calling next() since 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

Parameters:: rows - the number of rows
Returns:: true if on a row, false otherwise.

JDBC 2.0 Give 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, then 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 creates the result set. The fetch size may be changed at any time.

Specified by:: setFetchSize in interface java.sql.ResultSet

refreshRow

public void refreshRow()
                throws java.sql.SQLException

JDBC 2.0 Refresh the value of the current row with its current 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 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

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 Move 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(). UpdateXXX()must be called before getXXX() on a column.

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
