Characteristics of Cursors
You can use cursors to work with sets of data on an ODBC data source. Cursors can:
- 
Represent some or all records in a single table.
 
 
- 
Represent some or all records in a multiple-table join.
 
 
- 
Represent no records.
 
 
- 
Be read-only or updatable at either the cursor or the field level.
 
 
- 
Be fully scrollable, meaning that you can move forward and backward through the records, or they can be forward-only scrolling.
 
 
- 
Exist on either the client or the server.
