SQLITE_QUERY(3) 														   SQLITE_QUERY(3)

sqlite_query - Executes a query against a given database and returns a result handle

SYNOPSIS

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

DESCRIPTION

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

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

	Executes an SQL statement given by the $query against a given database handle.

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

	This function will return a result handle or FALSE on failure. For queries that return rows, the result handle can then be used with func-
       tions such as sqlite_fetch_array(3) and sqlite_seek(3).

	Regardless of the query type, this function will return FALSE if the query failed.

       sqlite_query(3) returns a buffered, seekable result handle. This is useful for reasonably small queries where you need to be able  to  ran-
       domly  access  the  rows.  Buffered  result  handles  will  allocate memory to hold the entire result and will not return until it has been
       fetched.  If  you  only	need  sequential  access  to  the  data,  it  is  recommended  that  you   use	 the   much   higher   performance
       sqlite_unbuffered_query(3) instead.

NOTES

       Warning

	       SQLite will execute multiple queries separated by semicolons, so you can use it to execute a batch of SQL that you have loaded from
	      a file or have embedded in a script. However, this works only when the result of the function is not used - if it is used, only  the
	      first SQL statement would be executed. Function sqlite_exec(3) will always execute multiple SQL statements.

	       When executing multiple queries, the return value of this function will be FALSE if there was an error, but undefined otherwise (it
	      might be TRUE for success or it might return a result handle).

SQLITE_ARRAY_QUERY(3)													     SQLITE_ARRAY_QUERY(3)

sqlite_array_query - Execute a query against a given database and returns an array

SYNOPSIS

       array sqlite_array_query (resource  $dbhandle, string  $query, [int  $result_type = SQLITE_BOTH], [bool	$decode_binary = true])

DESCRIPTION

       array sqlite_array_query (string  $query, resource  $dbhandle, [int  $result_type = SQLITE_BOTH], [bool	$decode_binary = true])

       Object  oriented style (method): array SQLiteDatabase::arrayQuery (string  $query, [int	$result_type = SQLITE_BOTH], [bool  $decode_binary
       = true])

       sqlite_array_query(3) executes the given query and returns an array of the entire result set. It is similar to calling sqlite_query(3)  and
       then sqlite_fetch_array(3) for each row in the result set. sqlite_array_query(3) is significantly faster than the aforementioned.

       Tip

	      sqlite_array_query(3)  is  best suited to queries returning 45 rows or less. If you have more data than that, it is recommended that
	      you write your scripts to use sqlite_unbuffered_query(3) instead for more optimal performance.

PARAMETERS

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

	      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 $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.

       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 an array of the entire result set; FALSE otherwise.

       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 style

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

       Example #2

	      Object-oriented style

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