Class TyrexResultSetImpl

public final class TyrexResultSetImpl extends Object implements ResultSet

This class implements java.sql.ResultSet so that it can be returned by the various Tyrex jdbc classes that return java.sql.ResultSet objects. This is done so that java.sql.ResultSet#getStatement returns a Tyrex implementation, so that java.sql.ResultSet#getConnection returns the Tyrex java.sql.Connection implementation. The actual underlying connection can never be accessed.

This class is thread safe.

Constructor Detail

TyrexResultSetImpl

public TyrexResultSetImpl(ResultSet resultSet, TyrexConnection connection)
Create the TyrexResultSetImpl.

Parameters: _resultSet the underlying result set statement the statement that returns this result set.

TyrexResultSetImpl

public TyrexResultSetImpl(ResultSet resultSet, TyrexStatementImpl statement)
Create the TyrexResultSetImpl.

Parameters: _resultSet the underlying result set statement the statement that returns this result set.

Method Detail

absolute

public boolean absolute(int row)
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().

Returns: true if the cursor is on the result set; false otherwise

Throws: SQLException if a database access error occurs, the row is 0, or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

afterLast

public void afterLast()
Moves the cursor to the end of this ResultSet object, just after the last row. This method has no effect if the result set contains no rows.

Throws: SQLException if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

beforeFirst

public void beforeFirst()
Moves the cursor to the front of this ResultSet object, just before the first row. This method has no effect if the result set contains no rows.

Throws: SQLException if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

cancelRowUpdates

public void cancelRowUpdates()
Cancels the updates made to the current row in this ResultSet object. This method may be called after calling an updateXXX method(s) and before calling the method updateRow to roll back the updates made to a row. If no updates have been made or updateRow has already been called, this method has no effect.

Throws: SQLException if a database access error occurs or if this method is called when the cursor is on the insert row

Since: 1.2

See Also: What Is in the JDBC 2.0 API

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

Throws: SQLException if a database access error occurs

deleteRow

public void deleteRow()
Deletes the current row from this ResultSet object and from the underlying database. This method cannot be called when the cursor is on the insert row.

Throws: SQLException if a database access error occurs or if this method is called when the cursor is on the insert row

Inserts the contents of the insert row into this ResultSet objaect and into the database. The cursor must be on the insert row when this method is called.

Throws: SQLException if a database access error occurs, if this method is called when the cursor is not on the insert row, or if not all of non-nullable columns in the insert row have been given a value

Since: 1.2

See Also: What Is in the JDBC 2.0 API

isAfterLast

public boolean isAfterLast()
Indicates whether the cursor is after the last row in this ResultSet object.

Returns: true if the cursor is after the last row; false if the cursor is at any other position or the result set contains no rows

public boolean isBeforeFirst()
Indicates whether the cursor is before the first row in this ResultSet object.

Returns: true if the cursor is before the first row; false if the cursor is at any other position or the result set contains no rows

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: What Is in the JDBC 2.0 API

isFirst

public boolean isFirst()
Indicates whether the cursor is on the first row of this ResultSet object.

Returns: true if the cursor is on the first row; false otherwise

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: What Is in the JDBC 2.0 API

isLast

public boolean isLast()
Indicates 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.

Returns: true if the cursor is on the last row; false otherwise

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: What Is in the JDBC 2.0 API

last

public boolean last()
Moves the cursor to the last row in this ResultSet object.

Returns: true if the cursor is on a valid row; false if there are no rows in the result set

Throws: SQLException if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

moveToCurrentRow

public void moveToCurrentRow()
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.

Throws: SQLException if a database access error occurs or the result set is not updatable

Since: 1.2

See Also: What Is in the JDBC 2.0 API

moveToInsertRow

public void moveToInsertRow()
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. An updateXXX method must be called before a getXXX method can be called on a column value.

Throws: SQLException if a database access error occurs or the result set is not updatable

Since: 1.2

See Also: What Is in the JDBC 2.0 API

next

public boolean next()
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.

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

Throws: SQLException if a database access error occurs

previous

public boolean previous()
Moves the cursor to the previous row in this ResultSet object.

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

Returns: true if the cursor is on a valid row; false if it is off the result set

Throws: SQLException if a database access error occurs or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

refreshRow

public void refreshRow()
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 updateXXX 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.

Throws: SQLException if a database access error occurs or if this method is called when the cursor is on the insert row

Since: 1.2

See Also: What Is in the JDBC 2.0 API

relative

public boolean relative(int rows)
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 different from calling the method 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.

Returns: true if the cursor is on a row; false otherwise

Throws: SQLException if a database access error occurs, there is no current row, or the result set type is TYPE_FORWARD_ONLY

Since: 1.2

See Also: What Is in the JDBC 2.0 API

rowDeleted

public boolean rowDeleted()
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 this ResultSet object can detect deletions.

Returns: true if a row was deleted and deletions are detected; false otherwise

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: DatabaseMetaData#deletesAreDetected What Is in the JDBC 2.0 API

rowInserted

public boolean rowInserted()
Indicates whether the current row has had an insertion. The value returned depends on whether or not this ResultSet object can detect visible inserts.

Returns: true if a row has had an insertion and insertions are detected; false otherwise

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: DatabaseMetaData#insertsAreDetected What Is in the JDBC 2.0 API

rowUpdated

public boolean rowUpdated()
Indicates whether the current row has been updated. The value returned depends on whether or not the result set can detect updates.

Returns: true if the row has been visibly updated by the owner or another, and updates are detected

Throws: SQLException if a database access error occurs

Since: 1.2

See Also: DatabaseMetaData#updatesAreDetected What Is in the JDBC 2.0 API

setFetchDirection

public void setFetchDirection(int direction)
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.

Throws: SQLException if a database access error occurs or the result set type is TYPE_FORWARD_ONLY and the fetch direction is not FETCH_FORWARD

Since: 1.2

See Also: What Is in the JDBC 2.0 API Statement#setFetchDirection

setFetchSize

public void setFetchSize(int rows)
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 ResultSet object. 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 object that created the result set. The fetch size may be changed at any time.

Parameters: rows the number of rows to fetch

Throws: SQLException if a database access error occurs or the condition 0 <= rows <= this.getMaxRows() is not satisfied
