php - How to correct pagination in oracle? -


i showing user record of how many forms he/she has accepted , purpose using pagination in php. data fetched oracle database , shown in table. using pagination, when go on next page shows previous record's new records not shown.

<table> <tbody>     <?php     include('connect.php');     $user_name = $_session['username'];     $sql = oci_parse($conn,"select * userm user_name = '$user_name'");     $result = oci_execute($sql);      while(($row = oci_fetch_array($sql,oci_both)) != false ){         $approvedby = $row[1];     }     if(!isset($_get['page'])){         $_get['page'] = 0;     }else{         // convert page number integer         $_get['page'] = (int)$_get['page'];     }     $varpage = $_get['page'];     if($varpage == "" || $varpage == "1"){         $page1 = 0;     }else{         $page1 = ($varpage*6)-6;     }     $approvedby = strtoupper($approvedby);      $sql = oci_parse($conn,"select * formc upper(approvedby) = '$approvedby' , rownum < 7");     oci_execute($sql);      while(($row = oci_fetch_array($sql,oci_both)) != false )  {         $accountingno = $row[0];         ?>         <tr>             <td style="color:black"><?php echo  $row[0] ?></td>             <td style="color:black"><?php echo  $row[1] ?></td>             <td style="color:black"><?php echo  $row[2]  ?></td>             <td style="color:black"><?php echo $row[3]?></td>             <td style="color:black"><?php echo $row[4] ?></td>             <td style="color:black"><?php echo $row[7] ?></td>                  </tr>         <?php      }     ?> </tbody> </table>  <?php $sql1 = oci_parse($conn,"select * formc upper(approvedby) = '$approvedby'"); oci_execute($sql1); $count = oci_fetch_all($sql1,$abc); $a=$count/6; $a = ceil($a);  for($b=1;$b<=$a;$b++){     ?>     <a href="approvedlist.php?page=<?php echo $b?>" style="text-decoration;align:center: none;" class="btn btn-success "><?php echo $b." "; ?></a>     <?php } oci_close($conn); ?> </div>

this explained in the underground php , oracle manual, page 181:

the canonical paging query oracle8i onwards given on http://asktom.oracle.com:

select *   ( select a.*, rownum rnum          (your_query_goes_here -- including order by)          rownum <= max_row )   rnum >= min_row

here, min_row row number of first row , max_row row number of last row return.

there full example script:

<?php $c = oci_connect('hr', 'welcome', 'localhost/xe'); $mystmt = "select city locations order city"; $minrow = 4; // row number of first row return $maxrow = 8; // row number of last row return $pagesql = "select *             ( select a.*, rownum rnum                    ( $mystmt )                    rownum <= :maxrow)             rnum >= :minrow"; $s = oci_parse($c, $pagesql); oci_bind_by_name($s, ":maxrow", $maxrow); oci_bind_by_name($s, ":minrow", $minrow); oci_execute($s); oci_fetch_all($s, $res); var_dump($res); ?>

edit:

as mentioned christopher jones, in oracle >=12.1 there cleaner way using offset clause:

select * mytable order myfield offset x rows fetch next y rows

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
