Is there a way I can generate this query with cakePHP :
SELECT pl.zban_player_id 'Player', pl.display_info 'GUID', pl.source_group 'Source',
IF(pv.variable_value is not null, 1,0) as SyncProcessed
FROM banner_key_current bkc
INNER JOIN banner_key_current_ext bkce ON bkc.banner_key_id = bkce.banner_key_id
INNER JOIN operations op ON op.operation_id = bkc.operation_id
INNER JOIN players pl ON pl.zban_player_id = bkce.identifier
INNER JOIN playermap_now pmn ON pmn.zban_player_id = pl.zban_player_id
LEFT JOIN player_variables pv ON (pv.zban_player_id = pl.zban_player_id AND pv.variable_name = 'player_sync_processed')
WHERE bkc.date BETWEEN '2014-05-01' AND '2014-11-13'
AND op.category = 117
AND pmn.user_id IN (1)
Group By bkce.identifier
What I want to return is the alias field SyncProcessed based on the condition
I'v tried using joins but couldn't get this result
You can use custom query by using this :
$this->YourModel->query('your query here')

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:
SELECT
cvl.id caracteristica_valor_id,
cvl.nome caracteristica_valor_nome,
cvl.valor caracteristica_valor_valor,
ctp.id caracteristica_tipo_id,
ctp.nome caracteristica_tipo_nome,
ctp.codigo caracteristica_tipo_codigo,
ctp.tipo caracteristica_tipo_tipo,
COUNT(DISTINCT var.id_perfil_produto) quantidade_itens
FROM
caracteristica_variacao cvr
INNER JOIN caracteristica_valor cvl ON cvl.id = cvr.id_caracteristica_valor
INNER JOIN caracteristica_tipo ctp ON ctp.id = cvl.id_caracteristica_tipo
INNER JOIN variacao var ON var.id = cvr.id_variacao
INNER JOIN(
SELECT DISTINCT
ppr.id perfil_produto_id
FROM
perfil_produto ppr
INNER JOIN produto pro ON pro.id = ppr.id_produto
INNER JOIN(
SELECT ppr2.id AS id_perfil_sub,a
COUNT(var.id) AS qtd_variacoes,
SUM(var.quantidade_estoque) AS quantidade_estoque,
COALESCE(SUM(var.quantidade_estoque_reservada),0) AS quantidade_estoque_reservada,
MIN(var.disponibilidade) AS disponibilidade,
MIN(var.frete_gratis) AS frete_gratis,
MIN(var.preco_venda) AS preco_venda,
MAX(var.preco_listagem) AS preco_listagem
FROM
variacao var
LEFT JOIN perfil_produto ppr2 ON ppr2.id = var.id_perfil_produto
LEFT JOIN caracteristica_variacao cvr_1 ON cvr_1.id_variacao = var.id
LEFT JOIN caracteristica_valor cvl_1 ON cvl_1.id = cvr_1.id_caracteristica_valor
LEFT JOIN caracteristica_tipo ctp_1 ON ctp_1.id = cvl_1.id_caracteristica_tipo
WHERE
var.disponibilidade = 1
AND(
ctp_1.codigo = 'tamanho' AND cvl_1.valor IN('p')
)
GROUP BY
ppr2.id
) AS grp_var ON grp_var.id_perfil_sub = ppr.id
INNER JOIN produto_categoria prc ON pro.id = prc.produto_id
INNER JOIN categoria cat ON prc.categoria_id = cat.id
WHERE
pro.disponibilidade = 1 AND prc.categoria_id IN (164, 165, 166)
) AS produto ON produto.perfil_produto_id = var.id_perfil_produto
GROUP BY
cvl.id
ORDER BY
ctp.tipo ASC,
ctp.id
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 query
SELECT custconcompany, custconfirstname, custconlastname, custconemail, custconphone, shipaddress1, shipaddress2, shipcity, stateabbrv, shipzip, countryname, websitecheck.formfieldfieldvalue websitevalue, excludecheck.formfieldfieldvalue excludevalue
FROM obcisc_customers
JOIN ( (obcisc_shipping_addresses JOIN obcisc_countries
ON obcisc_shipping_addresses.shipcountryid = obcisc_countries.countryid)
LEFT JOIN obcisc_country_states
ON obcisc_shipping_addresses.shipstateid = obcisc_country_states.stateid
LEFT JOIN obcisc_formfieldsessions websitecheck
ON obcisc_shipping_addresses.shipformsessionid = websitecheck.formfieldsessioniformsessionid
LEFT JOIN obcisc_formfieldsessions excludecheck
ON obcisc_shipping_addresses.shipformsessionid = excludecheck.formfieldsessioniformsessionid)
ON obcisc_customers.customerid = obcisc_shipping_addresses.shipcustomerid
WHERE custgroupid = 11
AND websitecheck.formfieldfieldid = 24
AND excludecheck.formfieldfieldid = 30
AND excludecheck.formfieldfieldvalue != 'a:1:{i:0;s:3:"Yes";}'
ORDER BY shipstate, shipcity
This works great except I also need it to return rows where "excludecheck.formfieldfieldid=30" does not exist... right now it's not returning them
When writing a LEFT JOIN, any criteria on the table you're joining with should be put into the ON clause. If you put it into the WHERE clause, you'll filter out the results in the first table that don't have a matching row in the second table, because the NULL value that comes from the outer join will not match the criteria.
SELECT custconcompany, custconfirstname, custconlastname, custconemail, custconphone, shipaddress1, shipaddress2, shipcity, stateabbrv, shipzip, countryname, websitecheck.formfieldfieldvalue websitevalue, excludecheck.formfieldfieldvalue excludevalue
FROM obcisc_customers
JOIN obcisc_shipping_addresses
ON obcisc_customers.customerid = obcisc_shipping_addresses.shipcustomerid
JOIN obcisc_countries
ON obcisc_shipping_addresses.shipcountryid = obcisc_countries.countryid)
LEFT JOIN obcisc_country_states
ON obcisc_shipping_addresses.shipstateid = obcisc_country_states.stateid
LEFT JOIN obcisc_formfieldsessions websitecheck
ON obcisc_shipping_addresses.shipformsessionid = websitecheck.formfieldsessioniformsessionid
AND websitecheck.formfieldfieldid = 24
LEFT JOIN obcisc_formfieldsessions excludecheck
ON obcisc_shipping_addresses.shipformsessionid = excludecheck.formfieldsessioniformsessionid
AND excludecheck.formfieldfieldid = 30
AND excludecheck.formfieldfieldvalue != 'a:1:{i:0;s:3:"Yes";}')
WHERE custgroupid = 11
ORDER BY shipstate, shipcity
Another way to do it is by putting (excludecheck.formfieldfieldid = 30 OR excludecheck.formfieldfieldid IS NULL) in the WHERE clause. But this is more verbose and also I believe it's harder for MySQL to optimize, especially if you have several tables you're joining like this.
p = Patient.find(30)
p.patient_problems
The above code generates the following query
SELECT `patient_problem`.* FROM `patient_problem` WHERE `patient_problem`.`patient_id` = 30 AND (`patient_problem`.`record_status_id` = 1)
But is there any way to assign/use alias table_name like
p.patient_problems(:alias=>'p1') # just for Ex.. This code will not work
p.patient_problems(:alias=>'p2') # just for Ex.. This code will not work
So it will generate the following queries
SELECT `p1`.* FROM `patient_problem` AS `p1` WHERE `p1`.`patient_id` = 30 AND (`p1`.`record_status_id` = 1)
SELECT `p2`.* FROM `patient_problem` AS `p2` WHERE `p2`.`patient_id` = 30 AND (`p2`.`record_status_id` = 1)
Additional Info
My problem is when I try to use joins
p.patient_problems(:all,:joins=>joins)
I get this error
ActionView::Template::Error (Mysql2::Error: Not unique table/alias: 'patient_problem': SELECT `patient_problem`.* FROM `patient_problem` LEFT OUTER JOIN party on party.id = patient_problem.patient_id

left outer join user user1 on entered_by1.user_id = user1.id
left outer join party as party_user1 on party_user1.id = user1.person_id

Ofcourse I could do some string manipulation on the generated joins query and set alias to patient_problem. But I thought setting alias for associations would be more cleaner since the joins query generated are unpredictable(in my scenario)
I am not sure what the variable joins is or how it was constructed. To alias tables in a join build your query like
Rails 3
PatientProblem.joins("as p1 OUTER JOIN patient_problem as p2 on ...")
or
PatientProblem.find(:all, :joins => "as p1 OUTER JOIN patient_problem as p2 ON ...")
you can make singleton methods for that and write the query one time and use may time like
def self.p1
#your active record query here.
end
and call like
PatientProblem.p1
Update
You can simply change the table name in your code:
Patient.table_name="p2"
I'm not sure if this would break anything else though ... so good luck!
Orignal Answer
One solution may be to define a separate model for each type of patient_problem and then do something like this:
class PatientProblem2 < ActiveRecord::Base
self.set_table_name "p2"
...
end
Another solution may be to use the ActiveRecord query interface which will allows for significant query flexibility:
http://guides.rubyonrails.org/active_record_querying.html
Perhaps you can be more specific on the nature problem you are trying to solve.
So I have the following table, do_stock_movement, that looks like this:
stock_movement_id sm_number sm_source_id sm_destination_id
15164b86a7533d 145 1516478840ee29 151644d8bd63f2
15166b89d1a9fc 194 15165c481bd9d0 151659e632cd48
The columns sm_source_id and sm_destination_id both reference product points stored in do_product_points.
I'm using the following SQL query:
SELECT * FROM do_stock_movement
INNER JOIN do_product_points ON product_points_id = sm_source_id
WHERE sm_number = '145'
In do_product_points, there's a field called pp_name. I need the corresponding pp_name for both sm_source_id and sm_destination_id.
However, the query above will only return the pp_name for sm_source_id, or for sm_destination_id if you change the joined field to that.
What SQL query will return the corresponding pp_name for both sm_source_id and sm_destination_id?
I hope this is clear. Please ask questions if it isn't!
JOIN this table do_product_points one more times for the sm_destination_id:
SELECT
s.pp_name AS SourcePoint,
d.pp_name AS DestinationPoint,
...
FROM do_stock_movement AS m
INNER JOIN do_product_points s ON s.product_points_id = m.sm_source_id
INNER JOIN do_product_points d ON d.product_points_id = m.sm_destination_id
WHERE m.sm_number = '145'
You need join twice and use alias:
SELECT *, Src.pp_name, Dst.pp_name FROM do_stock_movement
INNER JOIN do_product_points as Src
ON Src.product_points_id = sm_source_id
INNER JOIN do_product_points as Dst
ON Dst.product_points_id = sm_destination_id
You need to join to the product_points table twice, once with source_id and once with destination_id:
SELECT * FROM do_stock_movement move
INNER JOIN do_product_points source ON source.product_points_id = move.sm_source_id
INNER JOIN do_product_points dest ON dest.product_points_id = move.sm_destination_id
WHERE sm_number = '145'
I'm trying to convert this SQL to HQL, but I found no way to do that left join.

and
m.nm_periodo = 2
and
mdcs_causa.id_mdc = mdcs.id_mdc
)
WHERE
mdcs.id_mdc = 5077
I thought I could put the nm_ano and nm_periodo conditions in the where clause, with an OR to m.id_item_controle is null but this OR condition didn't seem to work, even in SQL.
Another approach was to left join a sub query. That worked in SQL, but I think HQL doesn't support that.
It can be done with with keyword:
...
left join itens_controle.medicoes m with (m.nm_ano = 2013 and m.nm_periodo = 2 and mdcs_causa.id_mdc = mdcs.id_mdc)
where mdcs.id_mdc = 5077
Instead of explicit values you should supply them as arguments.
Read this in this pdf left join is used
as below:
Query getEBills =session.createQuery( session.createQuery( from " EBill ebill EBill
ebill
left join ebill.accountTransaction where
ebill.balance > 500";
Li li f l bi i li () ist listOfRowValues = getDebitTransactions.list();
for (Object[] singleRowValues : listOfRowValues) {
// pull off the EBill // pull off the EBill
EBill ebill = (EBill)singleRowValues[0];
I dont have any experience in HQL, i have pasted what i have found for you. hope this will help you in any way.
