+navigation</title><shortdesc>Describes how the functionality of the rowset cursor and cursor
+navigation.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The rowset cursor can navigate to all available rows in the rowset. The
+rows available depend on how the rowset is generated, and particularly on
+whether the rowset is an SQL view using an evaluation window. </p>
+<p>The cursor has two valid locations outside of the actual rowset, known
+as the Beginning and the End. Initially and also following a reset, the cursor
+is positioned at the beginning.</p>
+<p>As regards navigating to next and previous rows, the beginning is considered
+to lie immediately prior to the first row, and end is immediately following
+the last row. Navigating to the first row is equivalent to navigating to the
+next row from the beginning, which in an empty set takes the cursor to the
+end of the set (maybe not immediately obvious). A similar process holds for
+navigating to the last row of a set.</p>
+<p>When updating or inserting a row, the cursor is in a special state which
+prevents navigation until the update or insertion is completed.</p>
+<p>The cursor may also end up in two other states</p>
+<ul>
+<li id="GUID-91DD7C42-E668-579D-B58D-2F45FDF61DDF"><p>after deletion of the
+current row it is "in limbo" between the two neighbouring rows. Navigating
+to next and previous will move to the respective row.</p> </li>
+<li id="GUID-17BA2F54-A1FD-5796-AA2B-D59BF66CBBCD"><p>it may become invalid
+after an error during navigation: either due to failure in the store or file
+system, or due to loss of context when multiple rowsets are concurrently updating
+a table. Navigating to any fixed position (i.e. not next or previous) will
+restore the cursor.</p> </li>
+</ul>
