SQL server connection not working

This works for me in CI 4.4.6 with MS SQL Server Express 2019:

Code:

public array $sqlsrv = [
'DSN'        => '',
'hostname'  => '127.0.0.1\sqlexpress',
'username'  => 'user',
'password'  => 'pass',
'database'  => 'table',
'schema'    => 'dbo',
'DBDriver'  => 'SQLSRV',
'DBPrefix'  => '',
'pConnect'  => false,
'DBDebug'    => true,
'charset'    => 'utf8',
'swapPre'    => '',
'encrypt'    => false,
'failover'  => [],
'dateFormat' => [
'date'    => 'Y-m-d',
'datetime' => 'Y-m-d H:i:s',
'time'    => 'H:i:s',
],
];

Maybe this helps you... I had to remove the port and add dbo as schema.
