cubrid_move_cursor
(PECL CUBRID >= 8.3.0)
cubrid_move_cursor — Move the cursor in the result
説明
$req_identifier
, int $offset
, int $origin
= CUBRID_CURSOR_CURRENT): bool
The cubrid_move_cursor() function is used to move the
current cursor location of req_identifier
by the
value set in the offset
argument, to the direction
set in the origin
argument. To set the
origin
argument, you can use CUBRID_CURSOR_FIRST
for the first part of the result, CUBRID_CURSOR_CURRENT
for the current
location of the result, or CUBRID_CURSOR_LAST
for the last part of the
result. If origin
argument is not explicitly
designated, then the function uses CUBRID_CURSOR_CURRENT
as its default
value.
If the value of cursor movement range goes over the valid limit, then the
cursor moves to the next location after the valid range for the cursor.
For example, if you move 20 units in the result with the size of 10, then
the cursor will move to 11th place and return CUBRID_NO_MORE_DATA
.
