PDO_SQLSRV DSN - Connecting to MS SQL Server and SQL Azure databases

	The PDO_SQLSRV Data Source Name (DSN) is composed of the following elements:

	      o DSN prefix
		- The DSN prefix is sqlsrv:.

	      o APP - The application name used in tracing.

	      o ConnectionPooling - Specifies whether the connection is assigned from a connection pool (1 or TRUE) or not (0 or FALSE).

	      o Database - The name of the database.

	      o Encrypt - Specifies whether the communication with SQL Server is encrypted (1 or TRUE) or unencrypted (0 or FALSE).

	      o Failover_Partner  - Specifies the server and instance of the database's mirror (if enabled and configured) to use when the primary
		server is unavailable.

	      o LoginTimeout - Specifies the number of seconds to wait before failing the connection attempt.

	      o MultipleActiveResultSets - Disables or explicitly enables support for multiple active Result sets (MARS).

	      o QuotedId - Specifies whether to use SQL-92 rules for quoted identifiers (1 or TRUE) or to use  legacy  Transact-SQL  rules  (0	or
		false).

	      o Server - The name of the database server.

	      o TraceFile - Specifies the path for the file used for trace data.

	      o TraceOn - Specifies whether ODBC tracing is enabled (1 or TRUE) or disabled (0 or FALSE) for the connection being established.

	      o TransactionIsolation   -  Specifies  the  transaction  isolation  level.  The  accepted  values  for  this  option  are  PDO::SQL-
		SRV_TXN_READ_UNCOMMITTED, PDO::SQLSRV_TXN_READ_COMMITTED, PDO::SQLSRV_TXN_REPEATABLE_READ, PDO::SQLSRV_TXN_SNAPSHOT, and PDO::SQL-
		SRV_TXN_SERIALIZABLE.

	      o TrustServerCertificate	-  Specifies  whether the client should trust (1 or TRUE) or reject (0 or FALSE) a self-signed server cer-
		tificate.

	      o WSID - Specifies the name of the computer for tracing.

	      PDO_SQLSRV DSN examples

	       The following example shows how to connecto to a specified MS SQL Server database:

	      $c = new PDO("sqlsrv:Server=localhost;Database=testdb", "UserName", "Password");

	       The following example shows how to connect to a MS SQL Server database on a specified port:

	      $c = new PDO("sqlsrv:Server=localhost,1521;Database=testdb", "UserName", "Password");

	       The following example shows how to connecto to a SQL Azure database with server ID 12345abcde. Note that when you  connect  to  SQL
	      Azure with PDO, your username will be UserName@12345abcde (UserName@ServerId).

	      $c = new PDO("sqlsrv:Server=12345abcde.database.windows.net;Database=testdb", "UserName@12345abcde", "Password");

PDO.SQLITECREATEFUNCTION(3)						 1					       PDO.SQLITECREATEFUNCTION(3)

PDO
::sqliteCreateFunction - Registers a User Defined Function for use in SQL statements

SYNOPSIS

       public bool PDO::sqliteCreateFunction (string  $function_name, callable	$callback, [int  $num_args])

DESCRIPTION

       Warning

	      This  function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
	      a future release of PHP. This function should be used at your own risk.

	This method allows you to register a PHP function with SQLite as an UDF (User Defined Function), so that it can be called from within your
       SQL statements.

	The UDF can be used in any SQL statement that can call functions, such as SELECT and UPDATE statements and also in triggers.

PARAMETERS

	      o $function_name
		- The name of the function used in SQL statements.

	      o $callback
		- Callback function to handle the defined SQL function.

	      Note

		      Callback functions should return a type understood by SQLite (i.e. scalar type).

	      o $num_args
		- Hint to the SQLite parser if the callback function accepts a predetermined number of arguments.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      PDO.sqliteCreateFunction(3) example

	      <?php
	      function md5_and_reverse($string)
	      {
		  return strrev(md5($string));
	      }

	      $db = new PDO('sqlite:sqlitedb');
	      $db->sqliteCreateFunction('md5rev', 'md5_and_reverse', 1);
	      $rows = $db->query('SELECT md5rev(filename) FROM files')->fetchAll();
	      ?>

	In  this  example,  we	have a function that calculates the md5 sum of a string, and then reverses it. When the SQL statement executes, it
       returns the value of the filename transformed by our function. The data returned in $rows contains the processed result.

	The beauty of this technique is that you do not need to process the result using a foreach loop after you have queried for the data.

       Tip

	       You can use "PDO::sqliteCreateFunction" and "PDO::sqliteCreateAggregate" to override SQLite native SQL functions.

       Note

	       This method is not available with the SQLite2 driver. Use the old style sqlite API for that instead.
