PHP sqlsrv查询到数据库

Question

我正在从 MySQL 迁移到 MS SQL Server，并试图从例程表中获取所有数据。我已连接但不确定如何使用 sqlsrv 获取数据。这是我走了多远:

$conn_array = array (
    "UID" => "sa",
    "PWD" => "root",
    "Database" => "nih_bw",
);
$conn = sqlsrv_connect('BILAL', $conn_array);
if ($conn){
    echo "connected";
    $result = sqlsrv_query($db->db_conn,"SELECT * FROM routines");
}else{
    die(print_r(sqlsrv_errors(), true));
}
sqlsrv_close($conn);
?>

Answer 1

首先，如果我没记错的话，你正在将 sqlsrv_connect 结果存储到 $conn 中，这个结果不是一个类对象，它是一个资源，所以删除 $db->conn

此示例将连接，如果有从 sqlsrv_query 返回的资源，则获取资源

$conn_array = array (
    "UID" => "sa",
    "PWD" => "root",
    "Database" => "nih_bw",
);
$conn = sqlsrv_connect('BILAL', $conn_array);
if ($conn){
    echo "connected";
    if(($result = sqlsrv_query($conn,"SELECT * FROM routines")) !== false){
        while( $obj = sqlsrv_fetch_object( $result )) {
              echo $obj->colName.'<br />';
        }
    }
}else{
    die(print_r(sqlsrv_errors(), true));
}
