interface XResultSet
Description provides the navigation on 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. Developers Guide Database - Scrollable Result Sets

Methods' Summary
next | moves the cursor down one row from its current position.
isBeforeFirst | indicates whether the cursor is before the first row in the result set.
isAfterLast | indicates whether the cursor is after the last row in the result set.
isFirst | indicates whether the cursor is on the first row of the result set.
isLast | indicates whether the cursor is on the last row of the result set.
beforeFirst | moves the cursor to the front of the result set, just before the first row. Has no effect if the result set contains no rows.
afterLast | 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.
first | moves the cursor to the first row in the result set.
last | moves the cursor to the last row in the result set.
getRow | retrieves the current row number. The first row is number 1, the second number 2, and so on.
absolute | moves the cursor to the given row number in the result set.
relative | moves the cursor a relative number of rows, either positive or negative.
previous | moves the cursor to the previous row in the result set.
refreshRow | 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 SDBC 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 SDBC driver to fetch the latest value of a row from the database. The SDBC 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 XResultSet::updateRow() , then the updates made to the row are lost. Calling the method `refreshRow` frequently will likely slow performance.
rowUpdated | indicates whether the current row has been updated. The value returned depends on whether or not the result set can detect updates.
rowInserted | indicates whether the current row has had an insertion. The value returned depends on whether or not the result set can detect visible inserts.
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 the result set can detect deletions.
getStatement | returns the Statement that produced this ResultSet object. If the result set was generated some other way, such as by an XDatabaseMetaData method, this method returns NULL .

Methods' Details
next
boolean
next()
raises( | SQLException );
Description 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. Returns true if successful Throws SQLException if a database access error occurs.
isBeforeFirst
boolean
isBeforeFirst()
raises( | SQLException );
Description indicates whether the cursor is before the first row in the result set. Returns true if so Throws SQLException if a database access error occurs.
isAfterLast
boolean
isAfterLast()
raises( | SQLException );
Description indicates whether the cursor is after the last row in the result set. Returns true if so Throws SQLException if a database access error occurs.
isFirst
boolean
isFirst()
raises( | SQLException );
Description indicates whether the cursor is on the first row of the result set. Returns true if so Throws SQLException if a database access error occurs.
isLast
boolean
isLast()
raises( | SQLException );
Description indicates whether the cursor is on the last row of the result set. Note: Calling the method `isAtLast` may be expensive because the SDBC 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 so Throws SQLException if a database access error occurs.
beforeFirst
void
beforeFirst()
raises( | SQLException );
Description moves the cursor to the front of the result set, just before the first row. Has no effect if the result set contains no rows. Throws SQLException if a database access error occurs.
afterLast
void
afterLast()
raises( | SQLException );
Description 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. Throws SQLException if a database access error occurs.
first
boolean
first()
raises( | SQLException );
Description moves the cursor to the first row in the result set. Returns true if successful Throws SQLException if a database access error occurs.
last
boolean
last()
raises( | SQLException );
Description moves the cursor to the last row in the result set. Returns true if successful Throws SQLException if a database access error occurs.
getRow
long
getRow()
raises( | SQLException );
Description retrieves the current row number. The first row is number 1, the second number 2, and so on. Returns the current position Throws SQLException if a database access error occurs.
absolute
boolean
absolute( | [in] long | row )
raises( | SQLException );
Description 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 XResultSet::first() . Calling `moveToPosition(-1)` is the same as calling `moveToLast()`.
relative
boolean
relative( | [in] long | rows )
raises( | SQLException );
Description 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 first/last row. Calling `relative(0)` is valid, but does not change the cursor position. Note: Calling `relative(1)` is different from calling XResultSet::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. Parameter rows how many rows should be moved relative to the current row Returns true if successful Throws SQLException if a database access error occurs.
previous
boolean
previous()
raises( | SQLException );
Description 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 call `previous()` when there is no current row. Returns true if successful Throws SQLException if a database access error occurs.
refreshRow
void
refreshRow()
raises( | SQLException );
Description 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 SDBC 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 SDBC driver to fetch the latest value of a row from the database. The SDBC 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 XResultSet::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.
rowUpdated
boolean
rowUpdated()
raises( | SQLException );
Description 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 successful Throws SQLException if a database access error occurs.
rowInserted
boolean
rowInserted()
raises( | SQLException );
Description indicates whether the current row has had an insertion. The value returned depends on whether or not the result set can detect visible inserts. Returns true if successful Throws SQLException if a database access error occurs.
rowDeleted
boolean
rowDeleted()
raises( | SQLException );
Description 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. Returns true if successful Throws SQLException if a database access error occurs.
getStatement
::com::sun::star::uno::XInterface
getStatement()
raises( | SQLException );
Description returns the Statement that produced this ResultSet object. If the result set was generated some other way, such as by an XDatabaseMetaData method, this method returns NULL . Returns the statement object Throws SQLException if a database access error occurs.
