我有一个使用查询返回的结果集：

String query = "select Bookname, SubjectName from books join Subjects on Subjects.SubjectID = Books.subjectID where classID = '1a'";
ResultSet temp = null;
try
{
   Statement st = conn.createStatement();
   ResultSet rs = st.executeQuery(query);

   temp = rs;
}

我只是想知道是否可以将结果集转换为两个单独的数组：例如 BookName[] 和 BookSubject[] 以便我稍后可以在列表视图中显示它们？结果集和android中的这个概念相对较新

我不确定是否有其他人之前见过这个,但我几天前得到了一个Windows更新,因为我的android工作室无法打开.我得到的确切错误消息是:

Config path C:/windows/system32/config/systemprofile/.AndroidSudio.3/config is
 invalid. If you have modified the 'idea.config.path' property please make 
sure it is correct, otherwise please re-install the IDE. 

当我在管理员模式下运行它时,它会再次进行安装.我不希望每次打开它都要这样做.

我想要做的基础是检查用户值.

如果它们返回true并返回页面,否则返回false并打印空值.

$query = sprintf("SELECT * from Users where username = ? and password = ?");
$params1 = array( $username, $password);
$stmt = sqlsrv_query($conn, $query, $params1);
if ($stmt === false) 
{
    die(print_r(sqlsrv_errors(), true));
}

$Users = array();

while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
    $username1 = $row['username'];
    $password1= $row['password'];
}


$Users["username"] = $username1;
$Users["password"] = $password1;

//echo json_encode($Users);
echo "you are here";

if ($username1==null)
{
    return false;
    echo "null values";
}
else {
    return true;
    if (!empty($_SERVER['HTTP_REFERER'])) …
