SQLITE_UNBUFFERED_QUERY(3)												SQLITE_UNBUFFERED_QUERY(3)

sqlite_unbuffered_query - Execute a query that does not prefetch and buffer all data

SYNOPSIS

       resource sqlite_unbuffered_query (resource  $dbhandle, string  $query, [int  $result_type = SQLITE_BOTH], [string  &$error_msg])

DESCRIPTION

       resource sqlite_unbuffered_query (string  $query, resource  $dbhandle, [int  $result_type = SQLITE_BOTH], [string  &$error_msg])

       Object  oriented  style	(method):  SQLiteUnbuffered  SQLiteDatabase::unbufferedQuery  (string	$query, [int  $result_type = SQLITE_BOTH],
       [string	&$error_msg])

       sqlite_unbuffered_query(3) is identical to sqlite_query(3) except that the result that is returned is a sequential forward-only result  set
       that can only be used to read each row, one after the other.

	This  function	is ideal for generating things such as HTML tables where you only need to process one row at a time and don't need to ran-
       domly access the row data.

       Note

	       Functions such as sqlite_seek(3), sqlite_rewind(3), sqlite_next(3), sqlite_current(3), and sqlite_num_rows(3) do not work on result
	      handles returned from sqlite_unbuffered_query(3).

PARAMETERS

	      o $dbhandle
		- The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the
		object-oriented method.

	      o $query
		- The query to be executed.  Data inside the query should be properly escaped.

	      o $result_type
		-The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using  SQLITE_ASSOC
		will  return  only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers).
		SQLITE_BOTH will return both associative and numerical indices.  SQLITE_BOTH is the default for this function.

	      o $error_msg
		- The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched
		using the sqlite_last_error(3) function.

       Note

	      Two  alternative	syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the
	      first, where the $dbhandle parameter is the first parameter to the function.

RETURN VALUES

	Returns a result handle or FALSE on failure.

       sqlite_unbuffered_query(3) returns a sequential forward-only result set that can only be used to read each row, one after the other.

SQLITE_FETCH_ALL(3)													       SQLITE_FETCH_ALL(3)

sqlite_fetch_all - Fetches all rows from a result set as an array of arrays

SYNOPSIS

       array sqlite_fetch_all (resource  $result, [int	$result_type = SQLITE_BOTH], [bool  $decode_binary = true])

DESCRIPTION

       Object oriented style (method):
       array SQLiteResult::fetchAll ([int  $result_type = SQLITE_BOTH], [bool  $decode_binary = true])
       array SQLiteUnbuffered::fetchAll ([int  $result_type = SQLITE_BOTH], [bool  $decode_binary = true])

       sqlite_fetch_all(3)  returns  an  array	of  the  entire result set from the $result resource. It is similar to calling sqlite_query(3) (or
       sqlite_unbuffered_query(3)) and then sqlite_fetch_array(3) for each row in the result set.

PARAMETERS

	      o $result
		- The SQLite result resource. This parameter is not required when using the object-oriented method.

	      o $result_type
		-The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using  SQLITE_ASSOC
		will  return  only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers).
		SQLITE_BOTH will return both associative and numerical indices.  SQLITE_BOTH is the default for this function.

	      o $decode_binary
		-When the $decode_binary parameter is set to TRUE (the default), PHP will decode the binary encoding it applied to the data if	it
		was  encoded using the sqlite_escape_string(3). You should normally leave this value at its default, unless you are interoperating
		with databases created by other sqlite capable applications.

RETURN VALUES

	Returns an array of the remaining rows in a result set. If called right after sqlite_query(3),	it  returns  all  rows.  If  called  after
       sqlite_fetch_array(3), it returns the rest. If there are no rows in a result set, it returns an empty array.

       The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration
       option.

EXAMPLES

       Example #1

	      Procedural example

	      <?php
	      $dbhandle = sqlite_open('sqlitedb');
	      $query = sqlite_query($dbhandle, 'SELECT name, email FROM users LIMIT 25');
	      $result = sqlite_fetch_all($query, SQLITE_ASSOC);
	      foreach ($result as $entry) {
		  echo 'Name: ' . $entry['name'] . '  E-mail: ' . $entry['email'];
	      }
	      ?>

       Example #2

	      Object-oriented example

	      <?php
	      $dbhandle = new SQLiteDatabase('sqlitedb');

	      $query = $dbhandle->query('SELECT name, email FROM users LIMIT 25'); // buffered result set
	      $query = $dbhandle->unbufferedQuery('SELECT name, email FROM users LIMIT 25'); // unbuffered result set

	      $result = $query->fetchAll(SQLITE_ASSOC);
	      foreach ($result as $entry) {
		  echo 'Name: ' . $entry['name'] . '  E-mail: ' . $entry['email'];
	      }
	      ?>
