MYSQLI_STMT_ATTR_SET(3) 						 1						   MYSQLI_STMT_ATTR_SET(3)

mysqli_stmt::attr_set - Used to modify the behavior of a prepared statement

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::attr_set (int	$attr, int  $mode)

DESCRIPTION

       Procedural style
       bool mysqli_stmt_attr_set (mysqli_stmt  $stmt, int  $attr, int  $mode)

	Used to modify the behavior of a prepared statement. This function may be called multiple times to set several attributes.

PARAMETERS

	      o $
		stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).

	      o $attr
		- The attribute that you want to set. It can have one of the following values:

	      Attribute values

	      +-----------------------------------+---------------------------------------------------+
	      | 	   Character		  |						      |
	      | 				  |						      |
	      | 				  |		       Description		      |
	      | 				  |						      |
	      +-----------------------------------+---------------------------------------------------+
	      |MYSQLI_STMT_ATTR_UPDATE_MAX_LENGTH |						      |
	      | 				  |						      |
	      | 				  |  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.
