I'm not sure that your exact current query can be expressee using an inner join instead of the where clause. You might try:
SELECT DISTINCT r1.*
FROM retailer r1
INNER JOIN retailer r2
ON r1.company_id = r2.id
WHERE
r1.states = 1 AND
r1.newsletter.status = 1 AND
r2.muli_ret_id = 0
ORDER BY
r1.email;
I use select distinct to remove possible duplicates which could arise from the self join. But honestly, you current approach is fine, though I might use exists here:
SELECT r1.*
FROM retailer r1
WHERE
r1.states = 1 AND
r1.newsletter.status = 1 AND
EXISTS (SELECT 1 FROM retailer r2
WHERE r2.id = r1.company_id AND r2.muli_ret_id = 0)
ORDER BY
r1.email;
Hi I am trying to query a table that conatains multiple duplicates on Code,Amount and Status How will I do this if I only one to get a result group according to the client_group name and get the sum of amount under that group
SELECT `client`.`client_group`
, FORMAT(SUM(`Data_result`.`Data_result_amount` ),2) as sum
FROM
`qwer`.`Data_result`
INNER JOIN `qwer`.`Data`
ON (`Data_result`.`Data_result_lead` = `Data`.`Data_id`)
INNER JOIN `qwer`.`Data_status`
ON (`Data_result`.`Data_result_status_id` = `Data_status`.`Data_status_id`)
INNER JOIN `qwer`.`client`
ON (`Data`.`Data_client_id` = `client`.`client_id`)
WHERE `Data_status`.`Data_status_name` IN ('PAID') AND MONTH(`Data_result`.`result_ts`) = MONTH(CURRENT_DATE())
AND YEAR(`Data_result`.`result_ts`) = YEAR(CURRENT_DATE())
GROUP BY `client`.`client_group`
Result of said query:
Table
Try to distinct before run the 'sum' check whether this solve your problem
SELECT `client_group` , FORMAT(SUM(`Data_result_amount` ),2) as sum from (
SELECT DISTINCT `client`.`client_group` , `Data_result`.`Data_result_amount`
FROM
`qwer`.`Data_result`
INNER JOIN `qwer`.`Data`
ON (`Data_result`.`Data_result_lead` = `Data`.`Data_id`)
INNER JOIN `qwer`.`Data_status`
ON (`Data_result`.`Data_result_status_id` = `Data_status`.`Data_status_id`)
INNER JOIN `qwer`.`client`
ON (`Data`.`Data_client_id` = `client`.`client_id`)
WHERE `Data_status`.`Data_status_name` IN ('PAID') AND MONTH(`Data_result`.`result_ts`) = MONTH(CURRENT_DATE())
AND YEAR(`Data_result`.`result_ts`) = YEAR(CURRENT_DATE())
) T
GROUP BY `client_group`

I have table called "Cart". Fields are :
CartId
ClientId
ProductId
Qty
Now i am joining this table with ProductMaster to get ProductName and ProuctPrice
select cc.CartId,cc.ProductId,pm.ProductName,cc.Qty,
(pm.ProductPrice * cc.Qty) As SubTotal
from ClientCart as cc
inner join ProductMaster as pm on cc.ProductId = pm.ProductId
Now I want to genrate GrandTotal using dynamic field SubTotal. How Can i do this?
with CTE as
(
select cc.CartId,cc.ProductId,pm.ProductName,cc.Qty,
(pm.ProductPrice * cc.Qty) As SubTotal
from ClientCart as cc
inner join ProductMaster as pm on cc.ProductId = pm.ProductId
where cc.ClientId = #id
)
select *
from CTE
union
select null,null, null,null, sum(SubTotal) -- this is a grand total of all sub totals
from CTE
It's not the proper Rollup method, but neither is yours so this will work fine
Try this:
select subtable.CartId, sum(subtable.SubTotal)
from (
select cc.CartId,cc.ProductId,pm.ProductName,cc.Qty,
(pm.ProductPrice * cc.Qty) As SubTotal
from ClientCart as cc
inner join ProductMaster as pm on cc.ProductId = pm.ProductId
where cc.ClientId = #id ) subtable
group by subtable.CartId;
I have 3 tables (stars mach the ids from the table before):
product:
prod_id* prod_name prod_a_id prod_b_id prod_user
keywords:
key_id** key_word key_prod* kay_country
data:
id dat_id** dat_date dat_rank_a dat_traffic_a dat_rank_b dat_traffic_b
I want to run a query (in a function that gets a $key_id) that outputs all these columns but only for the last 2 dates(dat_date) from the 'data' table for the key_id inserted - so that for every key_word - I have the two last dat_dates + all the other variables included in my SQL query:
So... This is what I have so far. and I don't know how to get only the MAX vars. I tried using "max(dat_date)" in different ways that didn't work.
SELECT prod_id, prod_name, prod_a_id, prod_b_id, key_id, key_word, kay_country, dat_date, dat_rank_a, dat_rank_b, dat_traffic_a, dat_traffic_b
FROM keywords
INNER JOIN data
ON keywords.key_id = data.dat_id
INNER JOIN prods
ON keywords.key_prod = prods.prod_id
Is there a possability to do this with only one query?
EDIT (FOR IgorM):
public function newnew() {
$query = $this->db->query('WITH CTE AS
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY dat_id ORDER BY dat_date ASC) AS
RowNo FROM data
)
SELECT *
FROM CTE
INNER JOIN keywords
ON keywords.key_id = CTE.dat_id
INNER JOIN prods
ON keywords.key_prod = prods.prod_id
WHERE RowNo < 3
');
$result = $query->result();
return $result;
}
This is the error on the output:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CTE AS ( SELECT *, ROW_NUMBER() OVER (' at line 1
WITH CTE AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY dat_id ORDER BY dat_date ASC) AS RowNo FROM data ) SELECT * FROM CTE INNER JOIN keywords ON keywords.key_id = CTE.dat_id INNER JOIN prods ON keywords.key_prod = prods.prod_id WHERE RowNo < 3
For SQL
WITH CTE AS
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY dat_id ORDER BY dat_date ASC) AS
RowNo FROM data
)
SELECT *
FROM CTE
INNER JOIN keywords
ON keywords.key_id = CTE.dat_id
INNER JOIN prods
ON keywords.key_prod = prods.prod_id
WHERE RowNo < 3
For MySQL (not tested)
SET #row_number:=0;
SET #dat_id = '';
SELECT *,
#row_number:=CASE WHEN #dat_id=dat_id THEN #row_number+1 ELSE 1 END AS row_number,
#dat_id:=dat_id AS dat_id_row_count
FROM data d
INNER JOIN keywords
ON keywords.key_id = d.dat_id
INNER JOIN prods
ON keywords.key_prod = prods.prod_id
WHERE d.row_number < 3
The other approach is self joining. I don't want to take credit for somebody else's job, so please look on the following example:
ROW_NUMBER() in MySQL
Look for the following there:
SELECT a.i, a.j, (
SELECT count(*) from test b where a.j >= b.j AND a.i = b.i
) AS row_number FROM test a
If you only want to do this for one key_id at a time (as alluded to in your responses to other answers) and only want two rows, you can just do:
SELECT p.prod_id,
p.prod_name,
p.prod_a_id,
p.prod_b_id,
k.key_id,
k.key_word,
k.key_country,
d.dat_date,
d.dat_rank_a,
d.dat_rank_b,
d.dat_traffic_a,
d.dat_traffic_b
FROM keywords k
JOIN data d
ON k.key_id = d.dat_id
JOIN prods p
ON k.key_prod = p.prod_id
WHERE k.key_id = :key_id /* Bind in key id */
ORDER BY d.dat_date DESC
LIMIT 2;
Whether you want this depends on your data structure and whether there is more than one key/prod combination per date.
Another option limiting just the data rows would be:
SELECT p.prod_id,
p.prod_name,
p.prod_a_id,
p.prod_b_id,
k.key_id,
k.key_word,
k.key_country,
d.dat_date,
d.dat_rank_a,
d.dat_rank_b,
d.dat_traffic_a,
d.dat_traffic_b
FROM keywords k
JOIN (
SELECT dat_id,
dat_date,
dat_rank_a,
dat_rank_b,
dat_traffic_a,
dat_traffic_b
FROM data
WHERE dat_id = :key_id /* Bind in key id */
ORDER BY dat_date DESC
LIMIT 2
) d
ON k.key_id = d.dat_id
JOIN prods p
ON k.key_prod = p.prod_id;
If you want some kind of grouped results for all the keywords, you'll need to look at the other answers.
I think a window function is the best way to go. without knowing a lot about the structure of the data you can try a subquery of what you are trying to restrict and then joining that to the rest of the data. Then within the where clause restrict the rows you pull back.
select p.prod_id, p.prod_name, p.prod_a_id, p.prod_b_id,
t.key_id, t.key_word, t.kay_country, t.dat_date,
t.dat_rank_a, t.dat_rank_b, t.dat_traffic_a, t.dat_traffic_b
from
(
select
k.key_id, k.key_word, k.kay_country, d.dat_date, d.dat_rank_a,
d.dat_rank_b, d.dat_traffic_a, d.dat_traffic_b,
row_number() over (partition by dat_id order by dat_date desc) as 'RowNum'
from keywords as k
inner join
data as d on k.key_id = d.dat_id
) as t
inner join
prods as p on t.key_prod = p.prod_id
where tmp.RowNum <=2
This is a "groupwise max" problem. Reference. CTE does not exist in MySQL.
I'm not totally clear on how your tables are linked, but here is a stab:
SELECT
*
FROM
( SELECT #prev := '', #n := 0 ) init
JOIN
( SELECT #n := if(k.key_id != #prev, 1, #n + 1) AS n,
#prev := k.key_id,
d.*, k.*, p.*
FROM data d
JOIN keywords k ON k.key_id = d.dat_id
JOIN prods p ON k.key_prod = p.prod_id
ORDER BY
k.key_id ASC,
d.dat_date ASC
) x
WHERE n <= 2
ORDER BY k.key_id, n;
you can use this query:
select prod_id, prod_name, prod_a_id, prod_b_id, key_id, key_word,
kay_country, dat_date, dat_rank_a, dat_rank_b, dat_traffic_a, dat_traffic_b
from keywords where dat_date in (
SELECT MAX(dat_date) FROM keywords temp_1
where temp_1.prod_id = keywords.prod_id
union all
SELECT MAX(dat_date) FROM keywords
WHERE dat_date NOT IN (SELECT MAX(dat_date ) FROM keywords temp_2 where
temp_2.prod_id = keywords.prod_id)
)
I have multiple table for a project (sessions , charges and payments)
To get the sessions i'm doing the following :
SELECT
sess.file_id, SUM(sess.rate * sess.length) AS total
FROM
sess
WHERE sess.sessionDone = 1
GROUP BY sess.file_id
This will return the amount that a specific student should pay
I also have another table "charges"
SELECT
file_charges.file_id, SUM(file_charges.price) AS total_charges
FROM
file_charges
GROUP BY file_charges.file_id
And finally the payment query :
SELECT
file_payments.file_id, SUM(file_payments.paymentAmount) AS total_payment
FROM
file_payments
GROUP BY file_payments.file_id
Can i combine those 3 in a way to have :
Total = Payments - (Session + Charges)
Note that it could be negative so i could have file_id that exists in session , charges but not in payments and i could have a payment without sessions or charges ...
Edit : http://sqlfiddle.com/#!2/a90d9
One issue that needs to be addressed is whether one of these queries can be the "driver", in cases where we don't have rows for a given file_id returned by one or more of the queries. (e.g. there might be rows from sess, but none from file_payments. If we want to be sure to include every possible file_id that appears in any of the queries, we can get a list of all possible file_id with a query like this:
SELECT ss.file_id FROM sess ss
UNION
SELECT fc.file_id FROM file_charges fc
UNION
SELECT fp.file_id FROM file_payments fp
(NOTE: The UNION operator will remove any duplicates)
To get the specified resultset, we can use that query, along with "left joins" of the other three original queries. The outline of the query will be:
SELECT a.file_id, p.total_payment - ( s.total + c.total_charges)
FROM a
LEFT JOIN s ON s.file_id = a.file_id
LEFT JOIN c ON c.file_id = a.file_id
LEFT JOIN p ON p.file_id = a.file_id
ORDER BY a.file_id
In that statement a is a standin for the query that gets the set of all file_id values (as shown above). The s, c and p are standins for your three original queries, on sess, file_charges and file_payments, respectively.
If any of the file_id values is "missing" from any of the queries, we are going to need to substitute a zero for the missing value. We can use the IFNULL function to handle that for us.
This query should return the specified resultset:
SELECT a.file_id
, IFNULL(p.total_payment,0) - ( IFNULL(s.total,0) + IFNULL(c.total_charges,0)) AS t
FROM ( -- all possible values of file_id
SELECT ss.file_id FROM sess ss
UNION
SELECT fc.file_id FROM file_charges fc
UNION
SELECT fp.file_id FROM file_payments fp
) a
LEFT
JOIN ( -- the amount that a specific student should pay
SELECT sess.file_id, SUM(sess.rate * sess.length) AS total
FROM sess
WHERE sess.sessionDone = 1
GROUP BY sess.file_id
) s
ON s.file_id = a.file_id
LEFT
JOIN ( -- charges
SELECT file_charges.file_id, SUM(file_charges.price) AS total_charges
FROM file_charges
GROUP BY file_charges.file_id
) c
ON c.file_id = a.file_id
LEFT
JOIN ( -- payments
SELECT file_payments.file_id, SUM(file_payments.paymentAmount) AS total_payment
FROM file_payments
GROUP BY file_payments.file_id
) p
ON p.file_id = a.file_id
ORDER BY a.file_id
(The EXPLAIN for this query is not going to be pretty, with four derived tables. On really large sets, performance may be horrendous. But the resultset returned should meet the specification.)
Beware of queries that JOIN all three tables together... that will likely give incorrect results when there are (for example) two (or more) rows for the same file_id in the file_payment table.
There are other approaches to getting an equivalent result set, but the query above answers the question: "how can i get the results of these queries joined together into a total".
Using correlated subqueries
Here's another approach, using correlated subqueries in the SELECT list...
SELECT a.file_id
, IFNULL( ( SELECT SUM(file_payments.paymentAmount) FROM file_payments
WHERE file_payments.file_id = a.file_id )
,0)
- ( IFNULL( ( SELECT SUM(sess.rate * sess.length) FROM sess
WHERE sess.file_id = a.file_id )
,0)
+ IFNULL( ( SELECT SUM(file_charges.price) FROM file_charges
WHERE file_charges.file_id = a.file_id )
,0)
) AS tot
FROM ( -- all file_id values
SELECT ss.file_id FROM sess ss
UNION
SELECT fc.file_id FROM file_charges fc
UNION
SELECT fp.file_id FROM file_payments fp
) a
ORDER BY a.file_id
try this
SELECT sess.file_id, SUM(file_payments.paymentAmount) - (SUM(sess.rate * sess.length)+SUM(file_charges.price)) as total_payment FROM sess , file_charges , file_payments
WHERE sess.sessionDone = 1
GROUP BY total_payment
EDIT.
SELECT a.file_id
, IFNULL(p.total_payment,0) - ( IFNULL(s.total,0) + IFNULL(c.total_charges,0)) AS tot
FROM (
SELECT ss.file_id FROM sess ss
UNION
SELECT fc.file_id FROM file_charges fc
UNION
SELECT fp.file_id FROM file_payments fp
) a
LEFT JOIN (
SELECT sess.file_id, SUM(sess.rate * sess.length) AS total
FROM sess
WHERE sess.sessionDone = 1
GROUP BY sess.file_id
) s
ON s.file_id = a.file_id
LEFT JOIN (
SELECT file_charges.file_id, SUM(file_charges.price) AS total_charges
FROM file_charges
GROUP BY file_charges.file_id
) c
ON c.file_id = a.file_id
LEFT JOIN (
SELECT file_payments.file_id, SUM(file_payments.paymentAmount) AS total_payment
FROM file_payments
GROUP BY file_payments.file_id
) p
ON p.file_id = a.file_id
ORDER BY a.file_id
