Get Scroll Insensitive Cursor command

Syntax

GET SCROLL INSENSITIVE [WITH {HOLD|NOHOLD}]
   CURSOR Identifier AS
   String

WITH HOLD is the default attribute of the cursor. For a non-holdable cursor, use the WITH NOHOLD option.

Note: WITH NOHOLD is only available in Java 2 Platform, Standard Edition, v 1.4 (J2SE) or higher.

Description

Creates a scrollable insensitive cursor with the name of the Identifier. (It does this by issuing a createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY) call and then executing the statement with java.sql.StatementExecuteQuery request on the value of the String.)

If the String is a statement that does not generate a result set, the behavior of the underlying database determines whether an empty result set or an error is issued. If there is an error in executing the statement, no cursor is created.

ij sets the cursor name using a java.sql.Statement.setCursorName request. Behavior with respect to duplicate cursor names is controlled by the underlying database. Derby does not allow multiple open cursors with the same name.

Once a scrollable cursor has been created, you can use the follow commands to work with the result set:

Example

ij> autocommit off;
ij> get scroll insensitive cursor scrollCursor as
'SELECT * FROM menu';
ij> absolute 5 scrollCursor;
COURSE    |ITEM                |PRICE
-----------------------------------------------
entree    |lamb chop           |14
ij> after last scrollcursor;
No current row
ij> before first scrollcursor;
No current row
ij> first scrollcursor;
COURSE    |ITEM                |PRICE
-----------------------------------------------
