The closing of a ResultSet

When a ResultSet

Note: A ResultSet

that Statement

ResultSet

In SQL, a result table is retrieved through a cursor that is
named. The current row of a result set 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
FOR UPDATE
is omitted, the positioned updates may fail.
The JDBC API supports this SQL feature by providing the name of the
SQL cursor used by a ResultSet
object.
The current row of a ResultSet
object
is also the current row of this SQL cursor.

Gets the value of the designated column in the current row

This method will return the value of the given column as a

Java object type corresponding to the column's SQL type,

the driver returns a Java null

This method may also be used to read database-specific abstract data types.
In the JDBC 2.0 API, the behavior of method

is extended to materialize
data of SQL user-defined types.
If Connection.getTypeMap

the behavior of this method is as

cursor on the last row; calling the method absolute(-2)
moves the cursor to the next-to-last row, and so on.
If the row number specified is zero, the cursor is moved to before the first row.
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()

The updater methods are used to update column values in the
current row or the insert row. The updater methods do not
update the underlying database; instead the updateRow
or
insertRow
methods are called to update the database.
If the second argument is an InputStream
then the stream must contain
the number of bytes specified by scaleOrLength. If the second argument is a
Reader
then the reader must contain the number of characters specified
by scaleOrLength. If these conditions are not true the driver will generate a
SQLException
when the statement is executed.

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 updater 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.

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 updater methods prior to inserting the row into the result set.
Only the updater, getter,
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 updater method must be called before a
getter method can be called on a column value.

Retrieves the value of the designated column in the current row

object and will convert from the
SQL type of the column to the requested Java data type, if the
conversion is supported. If the conversion is not
supported or null is specified for the type, a

At a minimum, an implementation must support the conversions defined in
Appendix B, Table B-3 and conversion of appropriate user defined SQL
types to a Java type which implements SQLData
, or Struct

Additional conversions may be supported and are vendor defined.

This method should be implemented as a low-cost operation compared to unwrap
so that
callers can use this method to avoid expensive unwrap
calls that may fail. If this method
returns true then calling unwrap
with the same argument should succeed.isWrapperFor
