The following query only work when I have a reference in the table wm_purchased_products.purchased_article_id but when this is empty mysql_num_rows return 0
The query is:
SELECT (SUM(wm_products_quantities.new_quantity) - SUM(wm_purchased_products.purchased_article_total) ) AS stock_restante,
wm_products_wall.nombre,
wm_products_wall.detalles,
wm_products_wall.price,
wm_products_wall.image_full,
wm_products_wall.fecha,
wm_products_wall.article_hashid
FROM wm_products_wall,
wm_products_quantities,
wm_purchased_products
WHERE wm_products_wall.categoria = '$new_rquery_xp'
AND wm_products_wall.article_hashid = wm_products_quantities.hashid_ref
AND wm_products_wall.article_hashid = wm_purchased_products.purchased_article_id
GROUP BY wm_products_wall.article_hashid
ORDER BY stock_restante ASC
How to build this query to work when I have no record in the table wm_purchased_products.purchased_article_id
Your code FROM wm_products_wall, wm_products_quantities, wm_purchased_products means all three table are INNER JOIN with each other.(that is, each and every row in the first table is joined to each and every row in the second table and so on.)
You can let wm_products_wall LEFT JOIN with wm_purchased_products, so do wm_purchased_products.
SELECT
(SUM(wm_products_quantities.new_quantity) - SUM(wm_purchased_products.purchased_article_total) ) AS stock_restante,
wm_products_wall.nombre, wm_products_wall.detalles, wm_products_wall.price,
wm_products_wall.image_full, wm_products_wall.fecha,
wm_products_wall.article_hashid
FROM wm_products_wall
LEFT OUTER JOIN wm_products_quantities
ON wm_products_wall.article_hashid = wm_products_quantities.hashid_ref
LEFT OUTER JOIN wm_purchased_products
ON wm_products_wall.article_hashid = wm_purchased_products.purchased_article_id
WHERE wm_products_wall.categoria = '$new_rquery_xp'
GROUP BY wm_products_wall.article_hashid
ORDER BY stock_restante ASC

How can I access data from an outer table in a SELECT, and use it in an WHERE inside a JOIN estructure?
Below is the current query:

I need the field ctp.codigo from the outer table inside thist part:
WHERE
var.disponibilidade = 1
AND(
ctp_1.codigo = 'tamanho' AND cvl_1.valor IN('p')
)
for this section to be as follows:
WHERE
var.disponibilidade = 1
AND(
(ctp.codigo != 'tamanho' AND ctp_1.codigo = 'tamanho' AND cvl_1.valor IN('p'))
OR
(ctp.codigo = 'tamanho')
)
It's not possible to reference columns from the outer query from inside an inline view query.
In the MySQL venacular, the inline view query is called a "derived table". And that name makes sense, because of the way MySQL processes it. The execution plan first materializes the inline view query into a temporary(-ish) table. Once that is done, then the outer query can run, referencing the contents of the derived table.
MySQL doesn't have available the columns from the outer query at the time the inline view query runs.
It is possible to reference columns from the outer query inside a subquery that appears for example in the SELECT list, or in the WHERE clause. We call a subquery that references columns from outer query a "correlated subquery".
I have the following table structure:
tbl_catalogue_state
In tbl_catalogue there is a part number 58674 that has three states in the tbl_catalogue_state_lk table. Here is the result when I run a query inner joining the three tables.
As expected there are multiple rows returned.
Is there a way to only return one row having the values for each catalgue_state_id on the same row?
I would also like the ability to ignore a row for example:
select tbl_catalogue.catalogue_part, tbl_catalogue_state.catalogue_state_id from tbl_catalogue
inner join tbl_catalogue_state_lk on tbl_catalogue.catalogue_id = tbl_catalogue_state_lk.catalogue_id
inner join tbl_catalogue_state on tbl_catalogue_state_lk.catalogue_state_id = tbl_catalogue_state.catalogue_state_id
where tbl_catalogue_state_lk.catalogue_state_id <> 1;
The above select still returns two rows.
UPDATE
I was able to use GROUP_CONCAT:
select tbl_catalogue.catalogue_part, GROUP_CONCAT(tbl_catalogue_state.catalogue_state_id) as cat_state from tbl_catalogue
inner join tbl_catalogue_state_lk on tbl_catalogue.catalogue_id = tbl_catalogue_state_lk.catalogue_id
inner join tbl_catalogue_state on tbl_catalogue_state_lk.catalogue_state_id = tbl_catalogue_state.catalogue_state_id
where tbl_catalogue_state_lk.catalogue_state_id <> 1
group by tbl_catalogue.catalogue_id;
My issue is the above statement still returns a row. I need it to return nothing.
I was able to use not exists:
select tc.catalogue_part, GROUP_CONCAT(tcs.catalogue_state_id) as cat_state from tbl_catalogue as tc
inner join tbl_catalogue_state_lk as tcsl on tc.catalogue_id = tcsl.catalogue_id
inner join tbl_catalogue_state as tcs on tcsl.catalogue_state_id = tcs.catalogue_state_id
where
not exists
(
select tcsl2.catalogue_state_id from tbl_catalogue_state_lk as tcsl2
where tcsl2.catalogue_state_id = 6 and tcsl2.catalogue_id = tc.catalogue_id
)
and
not exists
(
select tcsl3.catalogue_state_id from tbl_catalogue_state_lk as tcsl3
where tcsl3.catalogue_state_id = 1 and tcsl3.catalogue_id = tc.catalogue_id
)
and
not exists
(
select tcsl3.catalogue_state_id from tbl_catalogue_state_lk as tcsl3
where tcsl3.catalogue_state_id = 2 and tcsl3.catalogue_id = tc.catalogue_id
)
group by tc.catalogue_id;
I am trying to write a query that uses a LEFT OUTER JOIN on three tables. I have complete the first part to join two tables but I am stuck on intergarting the third table.
What I need is the "Status" field for the NXLHR_Valid to be included in the first query.
Below are my to queries, how would I include the SECOND query into the FIRST query
FIRST QUERY
SELECT NXLHR_SequenceNo_default.SeqNo, NXLHR_SequenceNo_default.SeqHeader, NXLHR_SequenceNo_default.SeqText, NXLHR_Hist.UniqueID, NXLHR_Hist.Room, NXLHR_Hist.Status, NXLHR_Hist.Water, NXLHR_Hist.AuditBy
FROM NXLHR_SequenceNo_default
LEFT OUTER JOIN NXLHR_Hist
ON NXLHR_SequenceNo_default.SeqID = NXLHR_Hist.SeqID
AND NXLHR_Hist.UniqueID = 'NXLHR01031472477564'
WHERE NXLHR_SequenceNo_default.SeqActive = 1
ORDER BY NXLHR_SequenceNo_default.OrderID
SECOND QUERY
SELECT NXLHR_Valid.UniqueID, NXLHR_Valid.Status
FROM NXLHR_Valid
WHERE NXLHR_Valid.UniqueID = 'NXLHR01031472477564'
Any help would be great. Thank you for your time.
SELECT d.SeqNo
, d.SeqHeader
, d.SeqText
, h.UniqueID
, h.Room
, h.Status
, h.Water
, h.AuditBy
, v.Status
FROM NXLHR_SequenceNo_default d
LEFT
JOIN NXLHR_Hist h
ON h.SeqID = d.SeqID
AND h.UniqueID = 'NXLHR01031472477564'
LEFT
JOIN NXLHR_Valid v
ON v.UniqueID = h.UniqueID
WHERE d.SeqActive = 1
ORDER
BY d.OrderID
Is there any workaround to get unique rows which are in zc_orders table? I only need comments field from zc_zc_orders_status_history (which have duplicate rows). This is my query:
SELECT

zc_orders_status_history.orders_status_id,
zc_customers.customers_email_address,
zc_customers.customers_telephone,

zc_customers
INNER JOIN zc_orders ON zc_orders.customers_id = zc_customers.customers_id
INNER JOIN zc_orders_status_history ON
zc_orders_status_history.orders_id = zc_orders.orders_id
where zc_orders_status_history.orders_status_id = 8
ORDER BY zc_orders_status_history.date_added DESC
SELECT DISTINCT
zc_orders_status_history.comments,

zc_customers
INNER JOIN zc_orders ON zc_orders.customers_id = zc_customers.customers_id

I have this query which i want to get rank from the data on my database
set #urut:=0;
set #rankhrg:=0;
select #urut:=#urut+1 as urut, a.id_tender, b.nama_tender, b.nomor_tender, b.tgl_close1 as tgl_close,
(SELECT rankhrg
from (select sum(tot_harga) as hrg_twr, id_rekanan, id_tender, #rankhrg:=#rankhrg+1 as rankhrg from tb_real_barang where id_tender = s.id_tender group by id_rekanan) as rank_harga
left join tb_master_tender s on s.id_tender = b.id_tender
where rank_harga.id_rekanan = a.id_rekanan
order by rank_harga.hrg_twr asc) as ranking
from tb_real_tender a
left join tb_master_tender b on a.id_tender = b.id_tender
where a.id_rekanan = 1
order by convert(a.id_tender,unsigned) desc
i want to pass id_tender into the select inside the select when i want to get rankhrg :
select sum(tot_harga) as hrg_twr, id_rekanan, id_tender,
#rankhrg:=#rankhrg+1 as rankhrg
from tb_real_barang
where id_tender = s.id_tender
group by id_rekanan
but I always get error that said that s.id_tender is unknown in where clause.
can someone guide me how to pass the parameter into that insert?
thank you :)
You are not joining with that table tb_master_tender and neither it's present in outer query FROM clause. So, you need to do a JOIN separately for that inner query like below
select sum(trb.tot_harga) as hrg_twr,
trb.id_rekanan,
trb.id_tender,
#rankhrg:=#rankhrg+1 as rankhrg
from tb_real_barang trb
left join tb_master_tender s on trb.id_tender = s.id_tender
group by trb.id_rekanan
