次のクエリコードを変更して、結果にテーブル名を含めるにはどうすればよいですか？

$ queryはデータベース内の4つのテーブルを検索し、結果にそれらがどのテーブルからのものであるかを含めたいと思います。4つのテーブルすべてに同じフィールドがあります。

次に、以下の$results_array[]配列に示すように結果を出力します。

前もって感謝します。

$query = mysql_query("select * from $TableName_1 where Topic = '$topic' AND 
((convert(`Post_Title` using utf8) like '%$term_1%') OR 
 (convert(`Post_Title` using utf8) like '%$term_2%') OR 
 (convert(`Post_Title` using utf8) like '%$term_3%') OR 
 (convert(`Post_Title` using utf8) like '%$term_4%')) 
UNION select * from $TableName_2 where Topic = '$topic' AND 
((convert(`Post_Title` using utf8) like '%$term_1%') OR 
 (convert(`Post_Title` using utf8) like '%$term_2%') OR 
 (convert(`Post_Title` using utf8) like '%$term_3%') OR 
 (convert(`Post_Title` using utf8) like '%$term_4%')) 
UNION select * from $TableName_3 where Topic = '$topic' AND 
((convert(`Post_Title` using utf8) like '%$term_1%') OR 
 (convert(`Post_Title` using utf8) like '%$term_2%') OR 
 (convert(`Post_Title` using utf8) like '%$term_3%') OR 
 (convert(`Post_Title` using utf8) like '%$term_4%')) 
UNION select * from $TableName_4 where Topic = '$topic' AND 
((convert(`Post_Title` using utf8) like '%$term_1%') OR 
 (convert(`Post_Title` using utf8) like '%$term_2%') OR 
 (convert(`Post_Title` using utf8) like '%$term_3%') OR 
 (convert(`Post_Title` using utf8) like '%$term_4%')) 
order by Post_Date desc LIMIT $items_to_query");

while($row = mysql_fetch_assoc($query)){
 $table_name = ?????????????????????;
 $db1 = $row['Post_Date']);
 $db2 = $row['Post_Title'];
 $db3 = $row['Author']);

 $results_array[] = '<div>'.$table_name.' - '.$db1.' - '.$db2.' - '.$db3.'</div>'."\n";
}
