MOVE — position a cursor
MOVE [direction
{ FROM | IN } ]cursorname
MOVE
repositions a cursor without retrieving any data.
MOVE
works exactly like the FETCH
command, except it only positions the cursor and does not return rows.
Refer to FETCH for details on syntax and usage.
On successful completion, a MOVE
command returns a command
tag of the form
MOVE count
The count
is the number
of rows that a FETCH
command with the same parameters
would have returned (possibly zero).
