⟩ How To Fetch the Next Row from a Cursor with a "FETCH" Statement?
When the result set is ready in a cursor, you can use a FETCH statement to retrieve one row from the result set in the same format as a SELECT statement. The FETCH statement has the following formats:
FETCH NEXT FROM cursor_name;
FETCH PRIOR FROM cursor_name;
FETCH FIRST FROM cursor_name;
FETCH LAST FROM cursor_name;
FETCH ABSOLUTE n FROM cursor_name;
FETCH RELATIVE n FROM cursor_name;
The tutorial exercise below shows you how FETCH statements are used to retrieve the first row and the second row back from a cursor:
USE GlobalGuideLineDatabase;
GO
DECLARE ggl_cursor CURSOR FOR
SELECT * FROM ggl_links;
OPEN ggl_cursor;
FETCH NEXT FROM ggl_cursor;
FETCH NEXT FROM ggl_cursor;
CLOSE ggl_cursor;
DEALLOCATE ggl_cursor;
GO
