Question

我正在尝试临时表空间中的列表文件。但它说＆＃34;没有选择行＆＃34;请解释为什么我没有将文件添加到表空间。

 $options = '';
    $filter=mysql_query("select afnumber from employees WHERE Status='Employed '");
    while($row = mysql_fetch_array($filter)) {
        $options .="<option >" . $row['afnumber'] . "</option>";
    }
    $menu="<form id='filter' name='filter' method='post' action=''>
    AFNumber : <select name='SelectAF' id='filter' style='color:grey;'>" . $options . "</select>
    Added hours: <input type='text' name='AddedHours' style=' padding: 10px;border: solid 2px #c9c9c9; width:50px; height:2px;'>
    <input type='submit' name='submit' value='Submit' style='width:80px; height:30px; text-align:center; padding:0px;'>
    </form>
    <br>
    ";

   /* if(isset($_POST['submit'])){

            $addedhours = $_POST['AddedHours'];
            $selectaf = $_POST['SelectAF'];
        if($addedhours == ""){
                  $sql="INSERT INTO `editedworkhours` (`AFNumber`,`AddedWH`) VALUES('$selectaf','$addedhours')";

                 $getResult =mysql_query($sql);

        }
        else{

                    $sql2 = "UPDATE editedworkhours SET AddedWH=$addedhours WHERE AFNumber=$selectaf";
                   $getResult =mysql_query($sql2);
        }
        } 

    echo $menu; */

Answer 1

您已将临时表文件添加到临时表空间，因此它不会显示在dba_data_files中。相反，您应该从dba_temp_files查询其信息：

SELECT FILE_NAME, BYTES FROM DBA_TEMP_FILES WHERE TABLESPACE_NAME = 'TESTRM';

Answer 2

临时文件不是数据文件。您需要查询dba_temp_files而不是列出它们。

select file_name, bytes from dba_temp_files where tablespace_name = 'TESTRM';

Answer 3

谢谢它有效。

SQL> SELECT FILE_NAME, BYTES FROM DBA_TEMP_FILES WHERE TABLESPACE_NAME = 'TESTRM';

FILE_NAME
--------------------------------------------------------------------------------
     BYTES
----------
/tmp/TESTRM/create/TESTRM/datafile/o1_mf_testrm_bvrywjkn_.tmp

+TESTDATA/rm/datafile/testrm_temp01.dbf

临时表空间＆＃34;没有选择行＆＃34;
