so.. Im trying to connect to a remote Microsoft SQL Database that requires applicationintent=ReadOnly.

If i setup a local ODBC Data source on my notebook and enable Application Intent to ReadOnly and use 'ANSI quoted identifiers' i can use Access and access the db and run queries access the data no problems.

But.. i need to access this from a PHP script, so i wrote the following :
<?php
    $user = '<username>';
    $pass = '<password>';
    $server = '<remoteMSSQLServer>';
    $database = 'dbname';
    $appintent = 'ReadOnly';

    $connection_string = "DRIVER={SQL Server};SERVER=$server;DATABASE=$database;ApplicationIntent=$appintent";
    $conn = odbc_connect($connection_string,$user,$pass);
if (!$conn){
    if (phpversion() < '4.0'){
      exit("Connection Failed: . $php_errormsg" );
    }
    else{
      exit("Connection Failed:" . odbc_errormsg() );
    }
}
?>

Open in new window


but when i try to browse to it, I only every get :

Connection Failed:[Microsoft][ODBC SQL Server Driver][SQL Server]The target database ('dbname') is in an availability group and is currently accessible for connections when the application intent is set to read only. For more information about application intent, see SQL Server Books Online.

any ideas what ive missed ?

PHP Ver. 5.6.24 running under Windows Server 2012 IIS with

extension=php_pdo_odbc.dll
extension=php_pdo_sqlsrv.dll
extension=php_sqlsrv.dll

Take a look at this connection string:
Dim SNACODBCConn As New Odbc.OdbcConnection(“Driver={SQL Server Native Client 11.0};server=aglisten;database=ag;trusted_connection=yes;applicationintent=readonly”)

Open in new window

See the difference between yours? Have you tried it like that?

Yeah your code is VB though.. i need to do it in PHP as i showed.

I cant use Trusted Connetion, as its not.. but i did change the Server type to use the 'SQL Server Native Client 11.0'  and i seem to now have a connection.

I think what the problem was is that the SQL Server Driver doesnt support the 'ApplicationIntent' argument perhaps ?
