	      | 				  |						      |
	      | 				  |  Setting	      to	  TRUE	       causes |
	      | 				  | mysqli_stmt_store_result(3) to update  the	meta- |
	      | 				  | data MYSQL_FIELD->max_length value. 	      |
	      | 				  |						      |
	      |   MYSQLI_STMT_ATTR_CURSOR_TYPE	  |						      |
	      | 				  |						      |
	      | 				  |  Type  of  cursor  to  open  for  statement  when |
	      | 				  | mysqli_stmt_execute(3) is invoked. $mode  can  be |
	      | 				  | MYSQLI_CURSOR_TYPE_NO_CURSOR   (the  default)  or |
	      | 				  | MYSQLI_CURSOR_TYPE_READ_ONLY.		      |
	      | 				  |						      |
	      |  MYSQLI_STMT_ATTR_PREFETCH_ROWS   |						      |
	      | 				  |						      |
	      | 				  |  Number of rows to fetch from server  at  a  time |
	      | 				  | when  using  a  cursor. $mode can be in the range |
	      | 				  | from 1 to the maximum value of unsigned long. The |
	      | 				  | default is 1.				      |
	      | 				  |						      |
	      +-----------------------------------+---------------------------------------------------+
	       If you use the MYSQLI_STMT_ATTR_CURSOR_TYPE option with MYSQLI_CURSOR_TYPE_READ_ONLY, a cursor is opened for the statement when you
	      invoke mysqli_stmt_execute(3). If there is already an open cursor from a previous mysqli_stmt_execute(3) call, it closes the  cursor
	      before  opening  a  new  one.  mysqli_stmt_reset(3)  also  closes  any  open cursor before preparing the statement for re-execution.
	      mysqli_stmt_free_result(3) closes any open cursor.  If you open a cursor for a prepared  statement,  mysqli_stmt_store_result(3)	is
	      unnecessary.

	      o $mode
		-The value to assign to the attribute.
