An R:BASE cursor is a valuable programming control structure that
enables traversal
reference over the records in a database. It is a pointer to rows in
a table that
can step through rows one by one, performing the same action on each
row. A cursor
can be set to point to all the rows in a table or to a subset of
rows. A cursor is
set using the DECLARE CURSOR command.
R:BASE supports several types of cursors and cursor structures including:
. Multi-Table Cursors
. Non-Updateable Cursors
. Nested Cursors
. Resettable Cursors
. Scrolling Cursors
All of the cursors above and examples of Optimizing Cursors are
described within
the R:BASE Cursors Explained technical document.
