Get Scroll Insensitive Cursor

Syntax

GET SCROLL INSENSITIVE CURSOR Identifier AS String

Description

Creates a scroll insensitive cursor with the name of the Identifier. (It does this by issuing a 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.)

NEW: This command only works in a JDK 1.2 environment.

Scroll insensitive cursors are not updateable.

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. Cloudscape does not allow multiple open cursors with the same name.

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

NEW: The Get Scroll Insensitive Cursor command is new in Version 3.0.
