fetch data from MSSQL server by ajax through Php

I am using AJAX to retrieve data from MSSQL server 2017 using Php and show those values in a text box. One MSSQL query is giving but other doesn't. In data.php when $stmt here is equals to SELECT rmtype FROM rmmaster, data is loading to text box in AJAX.php but when $stmt here is equals to SELECT * FROM rmmaster where rmnumber='102' this doesn't have values. But if run both the queries in sql managment studio, both are working and have results.

No error in connections, Just this working to one and not to other.

This is AJAX.php

    <input type="text" class="form-control" id="usr">

</body>

<script type="application/javascript">
    $('#element').on('click', function(e){
       $.ajax({
            url: 'data.php',
            type: 'GET',
            success: function(data){
               alert(data);
                $('#usr').val(data);

            }
        });
    });
</script>




</html>

This is DATA.php

 include_once ('home.php');
if( $conn === false ) {
    die( print_r( sqlsrv_errors(), true));
}


$name="102";

$stmt = $conn->query("SELECT * FROM rmmaster where rmnumber='$name'"); // this is not giving results
//$stmt = $conn->query("SELECT rmtype FROM rmmaster"); // this is giving answers

if( $stmt === false ) {
    die( print_r( sqlsrv_errors(), true));
}

if( $stmt->fetch() === false) {
    die( print_r( sqlsrv_errors(), true));
}


while ($row = $stmt->fetch()){
    echo ($row['rmtype'].$name);

}

home.php is the data connection to the sql server and no error in that file.
