A cursor is a temporary area of storage that is used to hold the information that is retreived from the SQL select statements.A cursor is mainly used to point to the table retrieved as a result of select query.
Types of cursor :
Serial cursor: In this the rows retreived from the resulting table are in sequential order .Also once EOF is reached the cursor can not be repositioned
Scrollable cursor:In this the rows retreived are based on the position mentioned on the FETCH statement
