 ===== Description =====
-There are 2 supported drivers that allow connections to Microsoft SQL Server databases. The first, **mssqlnative** allows connections from Windows Clients to Microsoft SQL Server databases versions 2008 and up, and uses the Microsoft Native Client libraries. The second, **mssql** allows connections from Unix based clients using the freetds libraries.
+There are 2 supported drivers that allow connections to Microsoft SQL Server databases.
+==== mssqlnative ====
+This driver, which runs on both Windows and Linux clients, allows connections to Microsoft SQL Server databases versions 2008 and up, and uses the Microsoft Native Client libraries. This driver is recommended for Windows Clients running PHP 5.3 and higher, and Linux Clients running PHP 7.0 and higher, and provides the fastest PHP connection.

+==== mssql====
+This allows connections from Unix based clients using the freetds libraries. It can be used with version 5.x of PHP

 ==== SQL Server 2003 ====
 Connecting to SQL server 2003 creates a difficulty There is no support for native client connections, and the alternative method, using php_mssql.dll was removed in PHP 5.3. The only alternative is to use a generic ODBC driver that does not require the Microsoft Native Client libraries.

 In order to return the dateTime as an object, the following action is required:
 <code php>
+$db = ADONewConnection('mssqlnative');
-$db = newAdoConnection('mssqlnative');
 $db->setConnectionParameter('ReturnDatesAsStrings',false);
 $db->connect('SERVER\SQLEXPRESS','user','password','NORTHWND');
 </code>
-=== Modifying The Format Of The Date ===
+===== Unicode Strings =====
-When methods like [[dictionary:createTableSql()]] are used against SQL Server databases, the 'D' [[dictionary:metaType]] creates a dateTime field, as opposed to a date field. This means that in portable applications, the ''Y-m-d'' portion of the date needs to be processed out of the returned field.
+You can set the character set to UTF-8 using:
 <code php>
-/**
+$db = ADONewConnection('mssqlnative');
-* Create the same column Against a MySQL, Oracle, SQL Server database
+$db->setConnectionParameter('characterSet','UTF-8');
-*/
+$db->connect('SERVER\SQLEXPRESS','user','password','NORTHWND');
-$dict->addColumnSql('some_table','some_date_column D Not Null');
-/*
-* Retrieve the data from column
-*/
-$d = $db->getOne('SELECT some_date_column FROM some_table');
-print $d;
-/*
-* With SQL Server, prints  1996-07-16 00:00:00.000000
-* With Other Databases, prints  1996-07-16
-*/
 </code>
-To create a portable application, use the following connection setting:
+===== Using Windows Authentication =====
+To use Windows, instead of SQL Server authentication, pass NULL as the user and password as shown below
 <code php>
-$db = newAdoConnection('mssqlnative');
+$db = ADONewConnection('mssqlnative');
-$db->setConnectionParameter('Type91Format','Y-m-d');
+$db->connect('SERVER\SQLEXPRESS',NULL,NULL,'NORTHWND');
-$db->connect('SERVER\SQLEXPRESS','user','password','NORTHWND');
-$d = $db->getOne('SELECT some_date_column FROM some_table');
-print $d;
-/*
-* Now prints a compatible value  1996-07-16
-*/
 </code>
-This setting modifies the format of the SQL Server [[https://msdn.microsoft.com/en-us/library/ms712408(v=vs.85).aspx|Type 91]] field. You can also use
-  $db->setConnectionParameter('Type93Format','Y-m-d');
-to modify the format of type 93 fields.
-** These settings have no effect if ''returnDatesAsStrings'' is set to false.**
