CUBRID_MOVE_CURSOR(3)							 1						     CUBRID_MOVE_CURSOR(3)

cubrid_move_cursor - Move the cursor in the result

SYNOPSIS

       int cubrid_move_cursor (resource  $req_identifier, int  $offset, [int  $origin = CUBRID_CURSOR_CURRENT])

DESCRIPTION

	The  cubrid_move_cursor(3)  function  is used to move the current cursor location of $req_identifier by the value set in the $offset argu-
       ment, 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.

PARAMETERS

	      o $req_identifier
		-Request identifier.

	      o $offset
		-Number of units you want to move the cursor.

	      o $origin
		-Location where you want to move the cursor from CUBRID_CURSOR_FIRST, CUBRID_CURSOR_CURRENT, CUBRID_CURSOR_LAST.

RETURN VALUES

       TRUE, when process is successful.

       FALSE, when process is unsucceful.
