SQL Query that inner joins on a certain condition - mysql

I have this Sql query which I use to create a view. But I need to refactor it, thus it will only perform inner join when SALES.PKY has a duplicate value or is not unique. How can I do it in a single query?
SELECT *
FROM SALES
INNER JOIN MAIN ON
REPLACE(MAIN.KEY,'-','') = SALES.PKY
AND REPLACE (MAIN.B,' ','') = SALES.SK
AND REPLACE (MAIN.P,' ','') = SALES.SP


could you use a with statement to filter like this?
with dups as (
select *
from sales
group by dup_value
having dup_value>1
)
select
dups.*
,main.*
from dups
inner join main
on dups_key=main_key


Here is one method:
SELECT *
FROM SALES INNER JOIN
MAIN
ON REPLACE(MAIN.KEY,'-','') = SALES.PKY AND
REPLACE(MAIN.B,' ','') = SALES.SK AND
REPLACE(MAIN.P,' ','') = SALES.SP JOIN
(SELECT s.PKY
FROM SALES s
GROUP BY s.PKY
HAVING COUNT(*) > 1
) ss
ON ss.PKY = SALES.PKY;

Mysql Select unique record based on multiple columns and display only group and sum amount

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`

SQL: How to get cells by 2 last dates from 3 different tables?

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)
)

How to deduct in group by query in sum in access

I have query like this ::
SELECT account.AccountNumber, account.NAME, Sum(agro.price * agro.qty) AS Expr1
FROM ((account
INNER JOIN data ON account.AccountNumber = data.acno)
INNER JOIN agro ON agro.BillNo = data.BillNo)
WHERE data.db='true'
GROUP BY account.AccountNumber, account.NAME;
I want to deduct another groupby query output in to Sum(agro.price * agro.qty) this
the another group by query is SELECT Sum(rs),acno
FROM jma group by acno;
i want to deduct Sum(agro.price * agro.qty)-Sum(rs) how its work please help me solve this

If I am understanding you correctly the following query may work for you:
SELECT subQ.AccountNumber, subQ.NAME, (subQ.subSum - jmaSum.jSum) AS FinalSum
FROM
(
SELECT a.AccountNumber, a.NAME, Sum(ag.price * ag.qty) AS subSum
FROM (account AS a
INNER JOIN data AS d ON a.AccountNumber = d.acno)
INNER JOIN agro AS ag ON ag.BillNo = d.BillNo
WHERE d.db = 'true'
GROUP BY a.AccountNumber, a.NAME
) AS subQ
LEFT JOIN
(
SELECT Sum(j.rs) AS jSum, j.acno
FROM jma AS j
GROUP BY j.acno
) AS jmaSum ON subQ.AccountNumber = jmaSum.acno

SQl join with count group by

I have two tables
one is
Receivesms(Matchdate,Matchtime,Keyword,SmsMessage,Mobileno)
another is
QAoptios(Keyword,Question,Answeroption,Matchdate,Matchtime)
I need to find the count of SmsMessage which have the value same as Answeroption on same Matchdate,Matchtime and same Keyword. and also i need to filter on Receivesms.Matchdate='2012-12-25 00:00:00.000'

SELECT
q.AnswerOption,
COUNT(SmsMessage) TheCount
FROM Receivesms r
INNER JOIN QAoptions q ON r.Matchdate = q.Matchdate
AND r.Matchtime = q.Matchtime
AND r.Keyword = q.keyword
GROUP BY q.AnswerOption;

use can use:
select count(*) from Recievesms r,QAoptios q
where
r.Matchdate = q.Matchdate
and
r.Matchtime = q.Matchtime
and
r. Keyword =q.Keyword
and
r.SmsMessage = q.Answeroption;
or
select count(*) from from Recievesms as r
inner join
QAoptios as q
on
r.SmsMessage = q.Answeroption;

try this one
SELECT count(*) from Receivesms as a inner join QAoptios as b on a.keyword=b.keyword
and a.matchtime=b.matchtime and a.matchdate=b.matchdate and a.value=b.answeroption

SELECT COUNT(R.SmsMessage)
FROM Receivesms R
INNER JOIN QAoptios Q ON
R.Keyword=Q.Keyword AND
R.Matchdate=Q.Matchdate AND
R.Matchtime=Q.Matchtime AND
R.SmsMessage=Q.AnswerOption
Or you can add GROUP BY clause if you want to show AnswerQuestion, like this:
SELECT Q.AnswerOption, COUNT(R.SmsMessage) as TheCount
FROM Receivesms R
INNER JOIN QAoptios Q ON
R.Keyword=Q.Keyword AND
R.Matchdate=Q.Matchdate AND
R.Matchtime=Q.Matchtime AND
R.SmsMessage=Q.AnswerOption
GROUP BY Q.AnswerOption
