public boolean absolute(int row) throws SQLException
Moves the cursor to the given row number in thisResultSet
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 methodabsolute(-1)
positions the cursor on the last row; calling the methodabsolute(-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: Callingabsolute(1)
is the same as callingfirst()
. Callingabsolute(-1)
is the same as callinglast()
.
- Returns:
true
if the cursor is on the result set;false
otherwise
- Since:
- 1.2
- See Also:

Gets the name of the SQL cursor used by thisResultSet

is thrown.

- 1.2
- See Also:
What Is in the JDBC 2.0 API
public boolean isLast() throws SQLException
Indicates whether the cursor is on the last row of thisResultSet
object. Note: Calling the methodisLast
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
- Since:
- 1.2
- See Also:

public boolean last() throws SQLException
Moves the cursor to the last row in thisResultSet

public void moveToCurrentRow() throws SQLException
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.
- Since:
- 1.2
- See Also:
What Is in the JDBC 2.0 API
public void moveToInsertRow() throws SQLException
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 theupdateXXX
methods prior to inserting the row into the result set. Only theupdateXXX
,getXXX
, andinsertRow
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 callinginsertRow
. AnupdateXXX
method must be called before agetXXX
method can be called on a column value.
- Since:
- 1.2
- See Also:
What Is in the JDBC 2.0 API
public boolean next() throws SQLException
Moves the cursor down one row from its current position. AResultSet
cursor is initially positioned before the first row; the first call to the methodnext
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 methodnext
will implicitly close it. AResultSet
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
public boolean previous() throws SQLException
Moves the cursor to the previous row in thisResultSet
object. Note: Calling the methodprevious()
is not the same as calling the methodrelative(-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

- 1.2
- See Also:
What Is in the JDBC 2.0 API
public void refreshRow() throws SQLException
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. TherefreshRow
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 callrefreshRow
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. IfrefreshRow
is called after calling anupdateXXX
method, but before calling the methodupdateRow
, then the updates made to the row are lost. Calling the methodrefreshRow
frequently will likely slow performance.
- Since:
- 1.2
- See Also:
What Is in the JDBC 2.0 API
public boolean relative(int rows) throws SQLException
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. Callingrelative(0)
is valid, but does not change the cursor position. Note: Calling the methodrelative(1)
is different from calling the methodnext()
because is makes sense to callnext()
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

- instance ofFBFetcher
that caused this event.newRow

public boolean rowDeleted() throws SQLException
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 thisResultSet
object can detect deletions.
- Returns:
true
if a row was deleted and deletions are detected;false

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