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.
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 a
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 following commands to work
with the result set:
