MYSQLI_STMT_SEND_LONG_DATA(3)						 1					     MYSQLI_STMT_SEND_LONG_DATA(3)

mysqli_stmt::send_long_data - Send data in blocks

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::send_long_data (int  $param_nr, string  $data)

DESCRIPTION

       Procedural style
       bool mysqli_stmt_send_long_data (mysqli_stmt  $stmt, int  $param_nr, string  $data)

	Allows to send parameter data to the server in pieces (or chunks), e.g. if the size of a blob exceeds the size of max_allowed_packet. This
       function can be called multiple times to send the parts of a character or binary data value for a column, which must be one of the TEXT	or
       BLOB datatypes.

PARAMETERS

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

	      o $param_nr
		- Indicates which parameter to associate the data with. Parameters are numbered beginning with 0.

	      o $data
		- A string containing data to be sent.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $stmt = $mysqli->prepare("INSERT INTO messages (message) VALUES (?)");
	      $null = NULL;
	      $stmt->bind_param("b", $null);
	      $fp = fopen("messages.txt", "r");
	      while (!feof($fp)) {
		  $stmt->send_long_data(0, fread($fp, 8192));
	      }
	      fclose($fp);
	      $stmt->execute();
	      ?>

MYSQLI_STMT_STORE_RESULT(3)						 1					       MYSQLI_STMT_STORE_RESULT(3)

mysqli_stmt::store_result - Transfers a result set from a prepared statement

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::store_result (void  )

DESCRIPTION

       Procedural style
       bool mysqli_stmt_store_result (mysqli_stmt  $stmt)

	You  must  call mysqli_stmt_store_result(3) for every query that successfully produces a result set ( SELECT, SHOW, DESCRIBE, EXPLAIN), if
       and only if you want to buffer the complete result set by the client, so that the subsequent  mysqli_stmt_fetch(3)  call  returns  buffered
       data.

       Note

	       It  is unnecessary to call mysqli_stmt_store_result(3) for other queries, but if you do, it will not harm or cause any notable per-
	      formance in all cases. You can detect whether the query produced a result set by checking if mysqli_stmt_result_metadata(3)  returns
	      NULL.

PARAMETERS

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

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
	      if ($stmt = $mysqli->prepare($query)) {

		  /* execute query */
		  $stmt->execute();

		  /* store result */
		  $stmt->store_result();

		  printf("Number of rows: %d.
", $stmt->num_rows);

		  /* free result */
		  $stmt->free_result();

		  /* close statement */
		  $stmt->close();
	      }

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
	      if ($stmt = mysqli_prepare($link, $query)) {

		  /* execute query */
		  mysqli_stmt_execute($stmt);

		  /* store result */
		  mysqli_stmt_store_result($stmt);

		  printf("Number of rows: %d.
", mysqli_stmt_num_rows($stmt));

		  /* free result */
		  mysqli_stmt_free_result($stmt);

		  /* close statement */
		  mysqli_stmt_close($stmt);
	      }

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      Number of rows: 20.
