I'm trying get last result from a table using the data_coleta (DATE) and servico_id as base. The query is working but is very slow. How can I optimize?
select t1.* from
amostra_ensaio_full t1
where
t1.cliente_id = 6 and t1.tipo_id <> 1
and t1.data_coleta = (SELECT max(s1.data_coleta) from amostra_ensaio_full s1 where t1.cliente_id = s1.cliente_id and s1.tipo_id <> 1 and s1.tipo_id = t1.tipo_id)
and t1.servico_id = (SELECT max(s2.servico_id) from amostra_ensaio_full s2 where t1.cliente_id = s2.cliente_id and s2.tipo_id <> 1 and s2.tipo_id = t1.tipo_id)
GROUP by t1.cliente_id , t1.tipo_id
You can probably speed up this query using indexes.
The query is:
select t1.*
from amostra_ensaio_full t1
where t1.cliente_id = 6 and t1.tipo_id <> 1 and
t1.data_coleta = (SELECT max(s1.data_coleta)
from amostra_ensaio_full s1
where t1.cliente_id = s1.cliente_id and
s1.tipo_id <> 1 and
s1.tipo_id = t1.tipo_id
) and
t1.servico_id = (SELECT max(s2.servico_id)
from amostra_ensaio_full s2
where t1.cliente_id = s2.cliente_id and
s2.tipo_id <> 1 and
s2.tipo_id = t1.tipo_id
)
GROUP by t1.cliente_id , t1.tipo_id;
You want the following index for the query: amostra_ensaio_full(cliente_id, tipo_id, servico_id).
The condition tipo_id <> 1 is unnecessary in the subquery, but it causes no harm.
Tks Gordon but the query still slow. Maybe I found the answer searching more.
SELECT a.*
FROM amostra_ensaio_full a
INNER JOIN
(
SELECT MAX(data_coleta) maxDate , tipo_id, cliente_id
FROM amostra_ensaio_full
GROUP BY cliente_id, tipo_id
) b ON a.cliente_id = b.cliente_id and a.tipo_id = b.tipo_id and b.maxDate = a.data_coleta
GROUP by a.cliente_id ,a.tipo_id

I have a query that is giving me different results when i enclosed it in Parentheses, however when I run it without Parentheses its giving me different results. I want to apply Union in between so I have to use Parentheses as without union doesn't work.

Same query if enclosed in Parentheses will give me different results.
Parentheses are not required for a UNION statement. The following 2 union statements both work and yield the same results.
SELECT 1 UNION SELECT 2;
(SELECT 1) UNION (SELECT 2);
I need the following sql query into laravel query or how can I run into laravel as it is. thanks
SELECT t.*
FROM (SELECT client_id,product_name, max(real_date) AS max_date
FROM api_hilbertis.transactions
WHERE active = 1 AND real_date <= '2019-03-01'
GROUP BY client_id, product_name) AS m
INNER JOIN api_hilbertis.transactions AS t
ON t.client_id = m.client_id
AND t.product_name = m.product_name
AND t.real_date = m.max_date
AND active = 1
ORDER BY real_date DESC;
You can use laravel raw queries.
Example HERE
So for your case it we could write something like:
$results = DB::select( DB::raw("
SELECT t.*
FROM (SELECT client_id,product_name, max(real_date) AS max_date
FROM api_hilbertis.transactions
WHERE active = 1 AND real_date <= '2019-03-01'
GROUP BY client_id, product_name) AS m
INNER JOIN api_hilbertis.transactions AS t
ON t.client_id = m.client_id
AND t.product_name = m.product_name
AND t.real_date = m.max_date
AND active = 1
ORDER BY real_date DESC"
));
EDIT: example with variables:
$someVariable = $request->input('some_variable');
$results = DB::select( DB::raw("SELECT * FROM some_table WHERE some_col = :somevariable"),
['somevariable' => $someVariable,]
);
I am trying to use an Case statement in a MySQL select query.
I am getting an error (Subquery returns more than 1 row)

when 'collect' then (SELECT collect_from_customer.num FROM collect_from_customer INNER JOIN mony ON mony.id_bill = collect_from_customer.id WHERE collect_from_customer.id=mony.id_bill )

end
) as idd
,mony.date FROM mony
please help me
thanks i found solution
SELECT m.come,m.go,m.details,m.id_bill,

when 'collect' then (SELECT collect_from_customer.num FROM collect_from_customer INNER JOIN mony m1 ON m1.id_bill = collect_from_customer.id WHERE collect_from_customer.id=m.id_bill LIMIT 1 )

I'm trying to divide the numeric results from 2 pretty different queries.
The end result should be Query 1 DIVIDED BY Query 2
Query 1 =
SELECT COUNT(DISTINCT(table1.ID)) AS count_1
FROM table1
INNER JOIN op
INNER JOIN Org
ON table1.EID = op.id
AND Op.OrgID = Org.ID
WHERE table1.TitleID = 123
AND op.BrandID = 1
AND op.Start <= NOW() AND op.End >= NOW();
Query 2 =
SELECT COUNT(DISTINCT user.id) AS count_2
FROM table1 INNER JOIN user INNER JOIN ur
ON table1.EID = user.id AND ur.userID = user.id
WHERE
user.BrandID = 1
AND table1.TitleID = 123
AND ur.role = 0
AND user.Inactive = 0;
Sure! You can use subselects to achieve this, though it will be pretty verbose!
SELECT
(
SELECT COUNT(DISTINCT(table1.ID)) AS count_1
FROM table1
INNER JOIN op
INNER JOIN Org
ON table1.EID = op.id
AND Op.OrgID = Org.ID
WHERE table1.TitleID = 123
AND op.BrandID = 1
AND op.Start <= NOW() AND op.End >= NOW()
) / (
SELECT COUNT(DISTINCT user.id) AS count_2
FROM table1 INNER JOIN user INNER JOIN ur
ON table1.EID = user.id AND ur.userID = user.id
WHERE
user.BrandID = 1
AND table1.TitleID = 123
AND ur.role = 0
AND user.Inactive = 0
);
Format however it feels the least ugly to you.
Use sub queries like this:
SELECT Q1.count_1 / Q2.Count_2
FROM
( ... Query1 ...) AS Q1
JOIN
( ... Query2 ...) AS Q2
ON 1=1
Replace Query1 and Query2 as your code.
Like this:
SELECT count_1 / count_2
FROM (SELECT COUNT(*) count_1 FROM foo) f
JOIN (SELECT COUNT(*) count_2 FROM bar) b ON 1=1;

I have the following query:
select
tt.ItemOrder, tt.DisplayVal as Task, tt.Responsible as ResParty,
tt.DaysDue,
ActualDate = (select convert(varchar(10), cnfmdate, 101) from ProSer where PId = #PID), PDate = #PDate
from
tblTimeline tt
where
tt.ID = 1
What I need to do is to put it in a view such that I can call the view simply using the PID.
I came up with the following and used the cross join:
create view view1 as
select
ps.PID, tt.ID, tt.ItemOrder, tt.DisplayVal as Task,
tt.Responsible as ResParty, tt.DaysDue,
ps.cnfmdate As ActualDate, ProgStartDate as ProgramDate
from
tblTimeline tt
cross join
ProSer ps
where
tt.ID = 1 and ps.cancelled = 0
Notice now, I can do the following
select *
from view1
where PID = '34343'
and then I can retrieve it from the view.
Now, I am not sure how to do similiarly with the following in which case I need to put it in a cross join similarly to how I did above.
Notice how actual date is somehat more involved. I need to use the cross table similarly to how I did it above but not as you can see, it is somewhat more involved.
(notice for this part, I will simly join to the view1 that I have above with UNION
select
tt.ItemOrder, tt.DisplayVal as Task, tt.Responsible as ResParty,
ActualDate = (
CASE
WHEN
NOT EXISTS(SELECT * FROM Spls WHERE RequestRcvd = 1 AND PID = #PID)
THEN
'N/A'
WHEN EXISTS (SELECT * FROM spls WHERE RequestRcvd = 1 AND RequestRcvdDate IS NOT NULL)
THEN
(SELECT CONVERT(VARCHAR(10),MAX(RequestRcvdDate),101) from spls WHERE RequestRcvd = 1 AND PID = #PID)
END
)
from
tblTimeline tt
where
tt.ID = 9
I need to know how I can create this in a cross join (which will be inside of a view) such that I can do the following similarly to how I did the above one
select *
from view1
where PID = '34343'
and then I can retrieve it from the view.
There might be a way to simplify the query, but the following should work:
select p.pid, tt.ItemOrder, tt.DisplayVal as Task,
tt.Responsible as ResParty,
ActualDate = (CASE WHEN NOT EXISTS(SELECT * FROM Spls WHERE RequestRcvd = 1 AND spls.PID = p.PID)
THEN 'N/A'
WHEN EXISTS (SELECT * FROM spls WHERE RequestRcvd = 1 AND RequestRcvdDate IS NOT NULL)
THEN (SELECT CONVERT(VARCHAR(10),MAX(RequestRcvdDate),101) from spls WHERE RequestRcvd = 1 AND spls.PID = p.PID)
END)
from tblTimeline tt cross join
poser p
where tt.ID = 9
All I did was add the cross join to poser and replace #PID with p.pid. The results is a subquery that contains a reference to a table at an outer level. Such a subquery is called a correlated subquery.
