I want to merge catetegory_id and subCategory_id into one column. But I don't know how to do it in flexible query. Below code is what I want to do
SELECT * FROM
(SELECT
ccr.targetpk as pk
FROM
Categories cc
JOIN Cat2CatRel ccr ON cc.pk = ccr.sourcepk
WHERE cc.p_code = '0106')
UNION SELECT CATE.pk as pk FROM CATEGORIES cate WHERE CATE.p_code = '0106'
I need a flexible query which works same as above code.
it is possible to do unions in flexible search queries. Here is an example like your case:
SELECT uniontable.PK FROM
(
{{
SELECT {cc:PK} as PK, {cc:code} AS CODE FROM {Categories AS cc}
WHERE {cc:p_code} LIKE '0106'
}}
UNION ALL
{{
SELECT {ccr:PK} as PK, {ccr:code} AS CODE FROM {Cat2CatRel AS ccr}
WHERE {ccr:p_code} LIKE '0106'
}}
) uniontable
Here you can find some more information about flex searches: Hybris Wiki

Is it possible to use .QueryMultiple (or some other method) in Dapper, and use the results of each former query to be used in the where clause of the next query, without having to do each query individually, get the id, and then .Query again, get the id and so on.
For example,
string sqlString = #"select tableA_id from tableA where tableA_lastname = #lastname;
select tableB_id from tableB WHERE tableB_id = tableA_id";
db.QueryMultiple.(sqlString, new {lastname = "smith"});
Is something like this possible with Dapper or do I need a view or stored procedure to accomplish this? I can use multiple joins for one SQL statement, but in my real query there are 7 joins, and I didn't think I should return 7 objects.
Right now I'm just using object.
You can store every previous query in table parameter and then first perform select from the parameter and query for next, for example:
DECLARE #TableA AS Table(
tableA_id INT
-- ... all other columns you need..
)
INSERT #TableA
SELECT tableA_id
FROM tableA
WHERE tableA_lastname = #lastname
SELECT *
FROM #TableA
SELECT tableB_id
FROM tableB
JOIN tableA ON tableB_id = tableA_id
Can somebody help me in converting below mentioned query in to Maximo's where clause:
select distinct workorder.wonum from workorder inner join [assignment]
On workorder.wonum=[assignment].wonum
inner join amcrew
On amcrew.amcrew=[assignment].amcrew
inner join amcrewlabor
On amcrewlabor.amcrew=amcrew.amcrew
inner join labor
On amcrewlabor.laborcode=labor.laborcode
inner join person
on labor.laborcode=person.personid where amcrewlabor.laborcode='KELLYB'
KELLYB is PERSONID used here for just reference.
If you are using a custom search query in Maximo, you can try prepending your with in (your query)
For example, if you're in Maximo's work order tracking module, the application uses select * from workorder by default. Any time you add a search filter such as work order number (wonum), then the query appends to run a query as select * from workorder where wonum = '123' if 123 is the work order number you entered.
Your where clause might look something like this:
wonum in (
select distinct workorder.wonum
from workorder
join assignment on workorder.wonum=assignment.wonum
join amcrew on amcrew.amcrew=assignment.amcrew
join amcrewlabor on amcrewlabor.amcrew=amcrew.amcrew
join labor on amcrewlabor.laborcode=labor.laborcode
join person on labor.laborcode=person.personid
where amcrewlabor.laborcode='KELLYB'
)
The SQL that is generated in Microsoft Access will not necessarily work in Maximo without some modification.
I searched a lot about sorting elements by sum of votes (in another model), like I do in SQL here :
SELECT item.* FROM item
LEFT JOIN (
SELECT
vote.item,
SUM(vote.value) AS vote.rating
FROM vote
GROUP BY vote.item
) AS res ON item.id = vote.item
ORDER BY res.rating DESC
Is there a way to do it via waterline methods ?
I think you can't do the left join with simple waterline methods, but you can use the .query method to execute your raw SQL syntax.
Sails MySQL adapter makes sum('field') conflict with sort('field'). It will generate SQL query like:
SELECT SUM(table.field) AS field FROM table ORDER BY table.field;
But I want:
SELECT SUM(table.field) AS field FROM table ORDER BY field;
It same as:
SELECT SUM(table.field) AS f FROM table ORDER BY f;
My solution is using lodash.sortBy() to process results. https://lodash.com/docs/4.16.4#sortBy
I'm fairly new to SQL and have started running into sub-queries as in this query below:
SELECT C.CustomerID
, C.Name
, ( Select PhoneNumber
FROM PhoneNumberTable P
WHERE P.CustomerID = C.CustomerID ) AS "PhoneNumber"
FROM CustomerTable C
Comparing to this query with a join below:
SELECT C.CustomerID
, C.Name
, P.PhoneNumber
FROM CustomerTable C
JOIN PhoneNumberTable P
ON P.customerID = C.customerID
Is there a difference in terms of efficiency/speed? The SQL I am working with has several sub-queries as I have shown above (no JOINs) and it is difficult to read.
joins in my experience tend to be faster, but sometimes you need a subquery.
you should also look into CTE they are very usefull and much easier (in my opinion) to manage
in your specific case i would use a join... because you are trying to join the 2 tables together.
Is it possible to do a join to a nested select statement in SubSonic 2.2? I am having trouble with this because I have to do a group by...
I.E.
select conn_company.company_name, SUM(t.quote_grand_total) as 'SUM' from conn_company
inner join
(SELECT *
FROM [dbo].[QuoteDBAll]
where [dbo].[QuoteDBAll].[quote_status_id] = 1
AND [dbo].[QuoteDBAll].[quote_ca_modified_date] BETWEEN '12/1/2000' AND '12/1/2009'
) t
on conn_company.company_id = t.company_id
group by company_name
having company_name = 'JACK'
Unfortunately you're not going to be able to convert that SQL into SubSonic 2 syntax. I would suggest you create a sql view based on your query and get SubSonic to generate a model from that instead.
