How to query SELECT SUM of Total from three different table php - php

Question

Hope you good Guys! I have a big problem on SELECT three different table and SUM there Total so that I may get Grand total of those three tables.
The table as follows, I just mention some of fields:
1:payment
id idnumber school_fee trans_fee
1 va03 10000 20000
2:payment_one
id idnumber school_fee trans_fee
1 va01 10000 30000
3:payment_two
id idnumber school_fee trans_fee
1 va02 40000 50000
I have already get 'Total' from each table, what I want is to SUM UP those Total I get, to have Grand total from those three tables.
Here my php codes;
1:payment:
<?php
//include mysql connect
if (isset($_GET['query']))
{
$query=$_GET['query'];
// Instructions if $_POST['value'] exist
}
// gets value sent over search form
$min_length = 3;
// you can set minimum length of the query if you want
if(strlen($query) >= $min_length){ // if query length is more or equal minimum
length then
$query = htmlspecialchars($query);
// changes characters used in html to their equivalents, for example: < to >
$query = mysql_real_escape_string($query);
// makes sure nobody uses SQL injection
$raw_results = mysql_query("SELECT
*,SUM(school_fee+trans_fee)
As Total FROM payment
WHERE (`class` LIKE '%".$query."%')") or die(mysql_error());
$raw_results2 = mysql_query("SELECT * FROM payment
WHERE (`class` LIKE '%".$query."%')") or die(mysql_error());
// * means that it selects all fields, you can also write: `id`, `title`, `text`
// articles is the name of our table
// '%$query%' is what we're looking for, % means anything, for example if $query
is Hello
// it will match "hello", "Hello man", "gogohello", if you want exact match use
`title`='$query'
// or if you want to match just full word so "gogohello" is out use '% $query %'
...OR ... '$query %' ... OR ... '% $query'
if(mysql_num_rows($raw_results) > 0){
if(mysql_num_rows($raw_results2) > 0){
// if one or more rows are returned do following
while($results = mysql_fetch_array($raw_results)){
while($results2 = mysql_fetch_array($raw_results2)){
// $results = mysql_fetch_array($raw_results) puts data from database into
array, while it's valid it does the loop
// posts results gotten from database(title and text) you can also show id
($results['id'])
}{
echo " Total amount of money payed by " .$results['class']
." "."class is " . $results ['Total'] . " /=Tshs";
echo"<br>"; echo"<br>";
}
}
}
}
}
?>
2:payment_one
<?php
//include mysql connect
if (isset($_GET['query']))
{
$query=$_GET['query'];
// Instructions if $_POST['value'] exist
}
// gets value sent over search form
$min_length = 3;
// you can set minimum length of the query if you want

Any help I'will be thankfully.

Answer 1

If I understand correctly, all of your three tables [payment][payment_one][payment_two] have same columns: id, idnumber, school_fee trans_fee.
You would be able to use one single table instead, and distinguish them by introducing a new column: tablenum, then it will be simple to obtain what you want. Please note both [id] and [tablenum] are primary key (composite primary key) now.
New table schema and the data would be (I'm not very sure about the purpose of your idnumber column):
[payment]
id tablenum idnumber school_fee trans_fee
1 0 va03 10000 20000
1 1 va01 10000 30000
1 2 va02 40000 50000
SQL example:
SELECT
school_fee,
trans_fee,
(school_fee + trans_fee) as 'total'
FROM payment WHERE id=1
