Now I want to SUM() all amount from con_trnsactions whose p_id from con_projects status = 1
I tried this and many more
mysql> SELECT (SELECT SUM(t.amount) FROM con_transactions t WHERE p.id=t.p_id) as total FROM con_projects p WHERE status='1'
+-------+
| total |
+-------+
| 14120 |
+-------+
AND
mysql> SELECT SUM(amount) from con_transactions;
+-------------+
| SUM(amount) |
+-------------+
| 14120 |
+-------------+
Both Are Same . But The subtraction will be like this.
mysql> SELECT 1800+100+999+1500+500+500+500+500+500+1000+3000+10+1000;
+---------------------------------------------------------+

+---------------------------------------------------------+
| 11909 |
+---------------------------------------------------------+
here is the all active project (con_trsaction.p_id=con_projects.id AND con_projects.status=1) id (p_id) From con_trsanction.amount
Try this:
SELECT SUM(t.amount)
FROM con_transactions t
INNER JOIN con_projects AS p ON t.p_id = p.id
WHERE p.status = 1
It's a simple join operation. Only 'active' projects will be accounted for in the summation.
SELECT SUM(amount) from con_transactions LEFT JOIN con_projects ON con_projects.id = con_transactions.p_id WHERE con_projects.status = 1;

The following is the query to use GROUP BY and MAX columns −
SELECT
group_get_max.goods_id, group_get_max.warehouse_id,
group_get_max.quantity,group_get_max.operated_at,group_get_max.id
FROM
group_get_max
INNER JOIN
(SELECT
group_get_max.warehouse_id,
group_get_max.goods_id,
MAX(group_get_max.operated_at) AS operated_at
FROM
group_get_max
WHERE
group_get_max.operated_at < '2020-03-23'
AND group_get_max.warehouse_id IN ('1' , '2', '3')
GROUP BY group_get_max.goods_id , group_get_max.warehouse_id) AS q
ON group_get_max.operated_at = q.operated_at
AND q.warehouse_id = group_get_max.warehouse_id
AND q.goods_id = group_get_max.goods_id
WHERE
group_get_max.warehouse_id IN ('1', '2','3')
After this query, I will get these data
+----------+--------------+----------+-------------+----+

But I just want to get max id after group by.
+----------+--------------+----------+-------------+----+
| goods_id | warehouse_id | quantity | operated_at | id |

How can I do? I'm waiting online
Instead of a join use a correlated subquery in the WHERE clause:
SELECT g.* FROM group_get_max AS g
WHERE g.operated_at < '2020-03-23' AND g.warehouse_id IN ('1' , '2', '3')
AND g.Id = (
SELECT Id FROM group_get_max
WHERE warehouse_id = g.warehouse_id AND goods_id = g.goods_id
AND operated_at < '2020-03-23' AND warehouse_id IN ('1' , '2', '3')
ORDER BY operated_at DESC, quantity DESC
LIMIT 1
)
See the demo.
For MySql 8.0+ you can use row_number() window function:
SELECT
t.Id, t.warehouse_id, t.goods_id,
t.price, t.inc, t.quantity, t.operated_at
FROM (
SELECT *,
row_number() over (partition by warehouse_id, goods_id order by operated_at DESC, quantity DESC) rn
FROM group_get_max
WHERE operated_at < '2020-03-23' AND warehouse_id IN ('1' , '2', '3')
) AS t
WHERE t.rn = 1
See the demo.
Results:
| Id | warehouse_id | goods_id | price | inc | quantity | operated_at |
| --- | ------------ | -------- | ----- | --- | -------- | ------------ |
| 8 | 1 | 3 | 100 | 50 | 200 | 2020-03-22 |

I want to find the number of rows that has a status 0 in descending order continuously. In this Case number would be 3

In this case it is four

So far I tried is processing the rows descending and finding it through php condition . Is there any better way to do it ?
I used this code in codeigniter and get the result
$this->db->select('count(id) as number');
$this->db->from('tablename');
$this->db->where('id > (select max(id) FROM tablename where status = 1)',
NULL, FALSE);
In mysql
SELECT count(id) as number FROM tablename
WHERE id > (select max(id) FROM tablename where status = 1)
I would like to count rows with the same serv AND spec. The below query counts the rows correctly:
SELECT *, COUNT(*) AS c
FROM table1
GROUP BY serv, spec
But I would like the output displayed as such:
Original:
+-----+------+------+
| id | serv | spec |
| 500 | 1 | 4 |
| 501 | 5 | 1 |
| 502 | 1 | 4 |
| 503 | 1 | 5 |
| 504 | 5 | 6 |
| 505 | 2 | 4 |
| 506 | 5 | 1 |
| 507 | 2 | 4 |
| 508 | 4 | 3 |
| 509 | 2 | 4 |
+-----+------+------+
Desired output:
+-----+------+------+-------+
| id | serv | spec | count |
| 500 | 1 | 4 | 2 |
| 502 | 1 | 4 | 2 |
| 503 | 1 | 5 | 1 |
| 505 | 2 | 4 | 3 |
| 507 | 2 | 4 | 3 |
| 509 | 2 | 4 | 3 |
| 508 | 4 | 3 | 1 |
| 501 | 5 | 1 | 2 |
| 506 | 5 | 1 | 2 |
| 504 | 5 | 6 | 1 |
+-----+------+------+-------+
Since MySQL doesn't support window functions, you have do the counts in a subquery, and then join this subquery to the table:
SELECT t.id, t.serv, t.spec, c.cnt
FROM
table1 t INNER JOIN (
SELECT serv, spec, COUNT(*) as cnt
FROM table1
GROUP BY serv, spec
) c ON t.serv = c.serv AND t.spec=c.spec
i have 3 tables. 2 reference table and one table transactions.

and i have this script that updates the values of hp for every minute(using cronjob here):
$sql = "UPDATE chara SET chara_hp = chara_hp +100";
$stmt = $db->prepare($sql);
$stmt->execute();
My Struggle:
how can i add +100 to the current value of chara_hp on chara table where the current chara_hp in the chara table does not exceed in the chara_base_hp from chara_base_stat table
basically all i want is to only regenerate those players hp if it there current hp is lesser than of there current chara_base_hp from chara_base_stat table
Note: the current chara_base_hp corresponds to the current level of the player and chara_class_id of the player.
so far i have this query here:
SELECT ch.chara_hp, bs.chara_base_hp FROM chara ch inner join chara_base_stat bs on(ch.chara_class_id = bs.chara_class_id and ch.chara_level = bs.chara_base_level)
that returns
+----------+---------------+
| chara_hp | chara_base_hp |
+----------+---------------+
| 13210 | 1000 |
| 14070 | 1000 |
| 14200 | 1000 |
| 13170 | 900 |
| 14100 | 900 |
| 13065 | 1100 |
| 14300 | 1100 |
+----------+---------------+
i want to do this in sql:
if(chara_hp < chara_base_hp){ update chara set chara_hp = chara_hp + 100 }
UPDATE
chara ch INNER JOIN chara_base_stat bs
ON ch.chara_class_id = bs.chara_class_id
AND ch.chara_level = bs.chara_base_level
SET
ch.chara_hp = LEAST(bs.chara_base_hp, ch.chara_hp + 100)
WHERE
ch.chara_hp < bs.chara_base_hp
