Info from two sql tables to one HTML table

Question

I Have tables like invoice & expenses output looks like this:

invoice

expenses:

How I can display these two tables in on table ordered by date ( Kuupäev) with my example first row must by from expenses 01-02-2015 next from invoice 14-08-2015 / 16-08-2015 / 16-08-2015 and then from expenses 17-08-2015

when invoice query is:

     $results = $mysqli->query(" SELECT * FROM tulu T1 
  INNER JOIN artikkel A1 on T1.artikkel_id = A1.artikkel_id 
  INNER JOIN liige L1 on T1.liige_id = L1.liige_id
  INNER JOIN maksja M1 on T1.maksja_id = M1.maksja_id
  ORDER BY kuup2ev ;

And table displayed with code:

print '<table class="mytable4">';
echo "<tr><th>Kuupäev </th><th>Artikkel </th><th>Maksja </th><th>Summa</th><th>Kommentaar</th><th>Sisestaja</th></tr>";
while($row = $results->fetch_array()) {
$timestamp = strtotime($row['kuup2ev']);

 print '<tr>';
  print '<td>'.$date = date('d-m-Y', $timestamp).'</td>';
   print '<td>'.$row["a_nimi"].'</td>';
    print '<td>'.$row["m_nimi"].'</td>';
    print '<td>'.$row["summa"].'</td>';
    print '<td>'.$row["kommentaar"].'</td>';
    print '<td>'.$row["nimi"].'</td>';
 print '</tr>';
}  
print '</table>';

The expenses query is:

SELECT * FROM kulu K1 
  INNER JOIN artikkel A1 on K1.artikkel_id = A1.artikkel_id 
  INNER JOIN liige L1 on K1.liige_id = L1.liige_id
  ORDER BY kuup2ev ;

sql tables: expenses

invoice

Answer 1

You can use UNION ALL like:

SELECT * FROM (
  (SELECT tulu_id, null as kulu_id, kuup2ev, artikkel_id, maksja_id, null as kogus, summa, kommentaar, liige_id, staatus, timestamp FROM tulu)
  UNION ALL
  (SELECT null as tulu_id, kulu_id, kuup2ev, artikkel_id, null as maksja_id, kogus, summa, kommentaar, liige_id, staatus, timestamp FROM kulu)
ORDER BY kuup2ev) T1
INNER JOIN artikkel A1 on T1.artikkel_id = A1.artikkel_id 
INNER JOIN liige L1 on T1.liige_id = L1.liige_id
LEFT JOIN maksja M1 on T1.maksja_id = M1.maksja_id

PS: Please correct the column name when trying this query.
