I have two sum quires referencing different tables in mySQL. How can I combine the two in order to calculate the difference between the two values for each user in the database?
Query 1:
SELECT tbl_users.name, tbl_holiday_allocation.`year`,
tbl_holiday_allocation.allocation,
tbl_holiday_allocation.carried_forward,
tbl_holiday_allocation.lieu_days,
SUM(tbl_holiday_allocation.allocation+tbl_holiday_allocation.carried_forward+tbl_holiday_allocation.lieu_days) AS TotalAllocation
FROM tbl_holiday_allocation
RIGHT JOIN tbl_users ON tbl_users.username = tbl_holiday_allocation.username
WHERE year = 2014 AND user_active = 1
AND (jobtitle like '".$search_string3."' OR department like '".$search_string3."')
GROUP BY tbl_users.name
ORDER BY tbl_users.id ASC
Query 2
SELECT tbl_users.name, Sum(tbl_holidays.NumberOfDays) AS ApprovedTotal
FROM tbl_users
LEFT JOIN tbl_holidays ON tbl_users.username = tbl_holidays.username
WHERE ((NumberOfDays < 6 AND LMStatus = 1 AND (department = 'Qual' or department = 'Quant' or department = 'Qual/Quant') AND RequestType = 'Holiday')
OR (NumberOfDays < 10 AND LMStatus = 1 AND (department = 'Accounts' or department = 'HR' or department = 'IT' or department = 'Support' or department = 'Operations') AND RequestType = 'Holiday')
OR (NumberOfDays > 5 AND NumberOfDays < 10 AND LMStatus = 1 AND HOStatus = 1 AND (department = 'Qual' or department = 'Quant' or department = 'Qual/Quant') AND RequestType = 'Holiday')
OR (NumberOfDays > 9 AND 'LMStatus' = 1 AND HOStatus = 1 AND CEOStatus = 1 AND (department = 'Qual' or department = 'Quant' or department = 'Qual/Quant') AND RequestType = 'Holiday')
OR (NumberOfDays > 9 AND LMStatus = 1 AND HOStatus = 1 AND CEOStatus = 1 AND (department = 'Qual' or department = 'Quant' or department = 'Qual/Quant') AND RequestType = 'Holiday') OR (NumberOfDays > 9 AND LMStatus = 1 AND CEOStatus = 1 AND (department = 'Accounts' or department = 'Support' or department = 'HR' or department = 'IT' or department = 'Operations') AND RequestType = 'Holiday'))
AND user_active = 1
AND (jobtitle like '".$search_string3."' OR department like '".$search_string3."')
GROUP BY tbl_users.name
ORDER BY tbl_users.id ASC
In the end I'd like to be able to take SUM TotalAllocation - SUM ApprovedTotal

FROM (

INNER JOIN

ON q1.username=q2.username;
$sql="select SUM(HA.allocation+HA.carried_forward+HA.lieu_days) AS TotalAllocation,Sum(H.NumberOfDays) AS ApprovedTotal where tbl_holiday_allocation as HA,tbl_holidays as H where your condition";
Hope this will be what you want.
Have a look in JOIN syntax

I use Codeigniter 3.1.11 and have some code which makes one big query to MySQL with an array. The time of a query with a limit of 30000 is about 9 seconds.
How can I reduce the request time? Maybe by using some indexes on my table, or do you know another method? If I need to use indexes, what indexes would I need to use and how can I use these indexes in my query on Codeigniter?
Code from model:
function rows_update() {
$query = $this->db->order_by('rating', 'DESC')->get_where('members', 'game_rating_and_balance_update_last_time <= now() - INTERVAL 1 DAY', '30000', '0');
$arrUpdateBatchData = [];
while ($row = $query->unbuffered_row('array'))
{
// some code here
$arrUpdateData = [
'UserID' => $row['UserID'],
'game_vault_balance' => $new_game_vault_balance,
'game_available_balance' => $new_game_available_balance,
'rating' => $rating_member,
'game_rating_and_balance_update_last_time' => date('Y-m-d H:i:s')
];
$arrUpdateBatchData[] = $arrUpdateData;
if (count($arrUpdateBatchData) > 500)
{
$this->db->update_batch('members', $arrUpdateBatchData, 'UserID');
$arrUpdateBatchData = [];
}
}
//update last items
if (count($arrUpdateBatchData) > 0)
{
$this->db->update_batch('members', $arrUpdateBatchData, 'UserID');
$arrUpdateBatchData = [];
}
return;
}
Raw query to MySQL with update_batch (I simply write only one row from an array):
UPDATE members SET game_vault_balance = CASE WHEN UserID = '9915075' THEN 803.60516004772 ELSE game_vault_balance END, game_available_balance = CASE WHEN UserID = '9915075' THEN 4.1253850908788 ELSE game_available_balance END, rating = CASE WHEN UserID = '9915075' THEN 0.24 ELSE rating END, game_rating_and_balance_update_last_time = CASE WHEN UserID = '9915075' THEN '2020-07-24 22:00:36' ELSE game_rating_and_balance_update_last_time END WHERE UserID IN('9915075')

I just having some problem of if/else or somewhat logical things in here, I have a fullcalendar that shows all the date that being reserve, I limit the reserve by 5 per date, but when I having a 2 or more reserved on the date and having reserve by other date, It gives me the same result as 4.
global $db;
$data = array();
$query = "SELECT * FROM reserve_master
INNER JOIN reserve_details
on reserve_master.reserve_id = reserve_details.reserve_id
INNER JOIN reserve_indicator
on reserve_master.reserve_id = reserve_indicator.reserve_id
WHERE reserve_indicator.touserid = '$id'
AND reserve_master.type = 'Repair' ";
$res = mysqli_query($db,$query);
$count = mysqli_num_rows($res);
$count = 5 - $count;//count the available slot
$date_changed = "";
$reserve_id = 0;
foreach ($res as $row)
{
date_default_timezone_set('Asia/Manila');
$current_timestamp = strtotime($row["dateend"] . '+1 day');
$time = date("Y/m/d",$current_timestamp);
if($row["datestart"] == $date_changed)
{
//This is for avoiding repeating graph on fullcalendar
}
else
{
if(empty($count))
{
$count = '0';
}
else
{
$count;
}
$data[] = array(
'id' => $row["reserve_id"],
'title' => $count,
'start' => $row["datestart"],
'end' => $time,
'color' =>getColor($row["status"])
);
$date_changed = $row["datestart"];
$reserve_id = $row["reserve_id"];
}
}
echo json_encode($data);

All i had tried is to get the right available on the 2nd of febuary 2018 and not the others.
The code is mess, I'm very sorry;
Problem is solved already;
I use eventLimit on fullcalendar and set it to 1
Count = 5 not subtracted by the num_rows
and few set on if-statement
Few answer I used rows and res as it is easy to indicate for results and rows, and i used it same as other queries.
Thank you.
With this code I'm getting news from the database and order it by column "views":
<?php
$getnewsinfo = mysql_query("SELECT * FROM news ORDER BY views DESC LIMIT 5");
while($newsinforow = mysql_fetch_array($getnewsinfo))
{
$newsid = $newsinforow['id'];
$title = $newsinforow['title'];
$author = $newsinforow['author'];
$date = date('d.m.Y', $newsinforow['date']);
$picture = $newsinforow['picture'];
$picture_desc = $newsinforow['picture_desc'];
$category = $newsinforow['category'];
$text = $newsinforow['text'];
?>
Now I want to order the news by views and by the number of comments, but I have no idea how.
Here is my database structure :
CREATE TABLE IF NOT EXISTS `news` (
`id` int(11) NOT NULL auto_increment,
`views` int(11) NOT NULL default '0',
`title` varchar(255) NOT NULL,
`author` varchar(255) NOT NULL,
`date` varchar(255) NOT NULL,
`picture` varchar(255) NOT NULL,
`picture_desc` varchar(255) NOT NULL,
`category` varchar(255) NOT NULL,
`text` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=6 ;
CREATE TABLE IF NOT EXISTS `news_comments` (
`id` int(11) NOT NULL auto_increment,
`news_id` int(11) NOT NULL,
`name` varchar(255) NOT NULL,
`email` varchar(255) NOT NULL,
`website` varchar(255) NOT NULL,
`text` text NOT NULL,
`date` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=16 ;
I also want to ask you... do you have any comments on the code and database structure ?
Try this sql
SELECT n.*,count(nc.id) as cnt FROM news as n, news_comments as nc where n.id = nc.news_id group by nc.news_id ORDER BY views DESC,cnt DESC LIMIT 5
I have these 2 queries and i would like to join them into one but i am unsure of how to go about it.
Query 1:
$query = "SELECT * FROM ".$db_tbl_comics." WHERE ".$db_fld_comics_publisher."='".$pub_id."'
AND ".$db_fld_comics_active."='1' GROUP BY ".$db_fld_comics_arc;
Query 2:
$q2 = mysql_query('SELECT '.$db_fld_arcs_title.' FROM '.$db_tbl_arcs.'
WHERE '.$db_fld_arcs_id.'="'.$result[$db_fld_comics_arc].'"');
Comics Table:
CREATE TABLE IF NOT EXISTS `comics` (
`id` varchar(255) NOT NULL,
`arc` int(255) NOT NULL,
`title` varchar(255) NOT NULL,
`issue` decimal(5,1) DEFAULT NULL,
`price` decimal(10,2) NOT NULL,
`plot` longtext NOT NULL,
`publisher` int(255) NOT NULL,
`isbn` varchar(255) NOT NULL,
`published` date NOT NULL,
`cover` varchar(255) NOT NULL DEFAULT './images/nopic.jpg',
`added` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`views` int(255) NOT NULL DEFAULT '0',
`active` int(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`),
UNIQUE KEY `arc` (`arc`,`title`,`issue`,`publisher`)
);
Arcs Table:
CREATE TABLE IF NOT EXISTS `arcs` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`title` varchar(255) NOT NULL,
`plot` longtext NOT NULL,
`added` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
UNIQUE KEY `title` (`title`)
);
What I need to do is get the Arcs Title from the arcs table for the respective comic arc.
You need to use INNER JOIN for that since I presume that records are present on both tables.
SELECT a.*, b.title
FROM comics a INNER JOIN arcs b
on a.id = b.id
WHERE a.Title = 'VALUEHERE'
displays all details from comics table and the title of the arc
as simple as (joining 2 queries in one, by selecting only the required field and using IN):
SELECT
'.$db_fld_arcs_title.'
FROM '.$db_tbl_arcs.'
WHERE '.$db_fld_arcs_id.' IN (
SELECT '.$db_fld_comics_arc.'
FROM '.$db_tbl_comics.'
WHERE '.$db_fld_comics_publisher.'='".$pub_id."'
AND '.$db_fld_comics_active.'='1' GROUP BY '.$db_fld_comics_arc.'
)

I will try to explain this better:
I have a given ID.
I would like to select one entry from users which is not the ID i have given
AND which user_id does not exist in matches
AND has visible = 1
AND where any country + city matches the given users country + city
Is this the correct way to do it (12 is an example of an given ID):
SELECT *
FROM users a
INNER JOIN areas ON areas.user_id = a.id
WHERE a.id NOT IN (SELECT user_id FROM matches)
AND NOT a.id = '12'
AND a.limit_age = '18:30'
AND a.visible = '1'
AND areas.country = 'sverige'
AND areas.city = 'gbg'
Sorry for the confusion :)
Ok, I'll make an attempt at this:
SELECT *
FROM users a
INNER JOIN areas ON areas.user_id = a.id
WHERE a.id NOT IN (SELECT user_id FROM matches)
AND a.visible = '1'
AND a.limit_age = '18:30'
AND a.limit_gender = 'f'
AND areas.country = ?
AND areas.city = ?;
This is SELECTing from "users", and returning a result only if that user also has an entry in the "areas" table. The first item in the WHERE clause ensures that a row will not be returned if the users.id (a.id) is found in the user_id field on the "matches" table. Next, I added checks for visible = 1, limit_age, and limit_gender as specified in his attempt. Finally, I left country and city parameterized so that they can be added as parameters in the php code. If anything that should give you a starting point.
