I have a BQL query joining three tables as follows:
foreach (PXResult<GLTran, Branch, xTACOpenSourceDetail> rec in
PXSelectJoin<GLTran,
InnerJoin<Branch,
On<GLTran.branchID, Equal<Branch.branchID>>,
InnerJoin<xTACOpenSourceDetail,
On<Branch.branchCD, Equal<xTACOpenSourceDetail.string03>,
And<xTACOpenSourceDetail.openSourceName, Equal<Constants.openSourceName>,
And<xTACOpenSourceDetail.dataID, Equal<Constants.privateer>>>>>>,
Where<Branch.branchCD, NotEqual<Required<Branch.branchCD>>,
And<GLTran.posted, Equal<True>,
And<GLTran.ledgerID, Equal<Required<GLTran.ledgerID>>,
And<GLTran.tranDate, GreaterEqual<Required<GLTran.tranDate>>>>>>,
OrderBy<Asc<xTACOpenSourceDetail.string01, Asc<GLTran.batchNbr>>>>.Select(Base, osdBranch.String03, ledger.LedgerID, tacsmlm.Date01))
I want to add one aggregated field, namely the sum of the GLTran.CuryDebitAmt grouped by GLTran.BatNbr and Branch.BranchCD.
I can easily do this in SQL using the SUM OVER functionality as follows:
SELECT SUM(GLTran.CuryDebitAmt) OVER (PARTITION BY GLTran.BatchNbr, Branch.BranchCD) as 'BatchTotal'
,GLTran.*
,Branch.*
,xTACOpenSourceDetail.*
FROM GLTran
Inner Join Branch
On GLTran.branchID = Branch.branchID
AND Branch.CompanyID = GLTran.CompanyID
Inner Join xTACOpenSourceDetail
On Branch.branchCD = xTACOpenSourceDetail.string03
And xTACOpenSourceDetail.openSourceName = 'TAC FM Map Company Branch'
And xTACOpenSourceDetail.dataID = 'Privateer'
AND xTACOpenSourceDetail.CompanyID = GLTran.CompanyID
Where Branch.branchCD <> '000 0000'
And GLTran.posted = 1
And GLTran.ledgerID = 6
And GLTran.tranDate >= '08/03/2017'
AND GLTran.CompanyID = 2
Order
By xTACOpenSourceDetail.string01 ASC
,GLTran.batchNbr ASC
...but I have no idea how to add this single summed field in BQL. Any help is appreciated.
You will use a PXSelectGroupBy and in your Aggreate for the BQL indicate which fields will "SUM" their values. Any field not called out will be the MAX value.
If you search SUM< in the Acumatica source you can find plenty of BQL examples. Here is a BQL Example from ARPaymentEntry. Only two (curyAdjdAmt & adjAmt) fields will contain a SUM while all other fields returned will be the MAX.
SOAdjust other = PXSelectGroupBy<SOAdjust,
Where<SOAdjust.voided, Equal<False>,
And<SOAdjust.adjdOrderType, Equal<Required<SOAdjust.adjdOrderType>>,
And<SOAdjust.adjdOrderNbr, Equal<Required<SOAdjust.adjdOrderNbr>>,
And<
Where<SOAdjust.adjgDocType, NotEqual<Required<SOAdjust.adjgDocType>>,
Or<SOAdjust.adjgRefNbr, NotEqual<Required<SOAdjust.adjgRefNbr>>>>>>>>,
Aggregate<GroupBy<SOAdjust.adjdOrderType,
GroupBy<SOAdjust.adjdOrderNbr,
Sum<SOAdjust.curyAdjdAmt,
Sum<SOAdjust.adjAmt>>>>>>.Select(this, adj.AdjdOrderType, adj.AdjdOrderNbr, adj.AdjgDocType, adj.AdjgRefNbr);
Another alternative solution for your question would be to create a PXProjection which could be the sum by group values which you then in your regular select include the projection table vs the base table in your BQL. I don't know the performance benefits vs one or the other - just another option.

Good day
I am trying to convert my SQL to BQL but I don't know how to do the NOT IN Statment in BQL. I used NotIn2 with search I am not sure if that is right?
I keep on getting time out issues if I use it so I can't test
SELECT INTran.*,
FROM INTran
JOIN INTranSplit ON INTran.RefNbr = INTranSplit.RefNbr
JOIN InventoryItem ON InventoryItem.InventoryID = INTran.InventoryID
WHERE INTran.LotSerialNbr NOT IN
(
SELECT LotSerialNbr
FROM SOShipLineSplit
)
AND InventoryItem.inventoryCD = 'NIS004';
I am going to use it in a foreach loop with the below:
foreach (INTran item in PXSelectJoin<
INTran,
LeftJoin<INTranSplit,
On<INTranSplit.refNbr, Equal<INTran.refNbr>>,
LeftJoin<InventoryItem,
On< INTran.inventoryID, Equal<InventoryItem.inventoryID>>>>,
Where<INTran.lotSerialNbr, NotIn2<Search<SOShipLineSplit.lotSerialNbr>>,
And<InventoryItem.inventoryCD, Equal<Required<InventoryItem.inventoryCD>>>>
>.Select(Base, "NIS004")){}
Well, you cannot implement NotIn with subselect that easily in BQL. But here is what you can do:
You can alter the select to get the same result using join:
PXSelectJoin<INTran,
InnerJoin<INTranSplit, On<...>,
InnerJoin<InventoryItem, On<...>,
LeftJoin<SOShipLineSplit, On<SOShipLineSplit.lotSerialNbr, Equal<INTran.lotSerialNbr>>>>>,
Where<InventoryItem.inventoryCD, Equal<Required<InventoryItem.inventoryCD>>,
And<SOShipLineSplit.ShipmentNbr, IsNull>>
In that example you will only select lines for which SOShipLineSplit was not found
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
I'm trying to figure out how to replicate the below query in SQLAlchemy
SELECT c.company_id AS company_id,
(SELECT policy_id FROM associative_table at WHERE at.company_id = c.company_id) AS policy_id_ref,
(SELECT `default` FROM policy p WHERE p.policy_id = policy_id_ref) AS `default`,
FROM company c;
Note that this is a stripped down, basic example of what I'm really dealing with. The actual schema supports data and relationship versioning that requires the subqueries to include additional conditions, sorting, and limiting, making it impractical (if not impossible) for them to be joins.
The crux of the problem is in how the second subquery relies on policy_id_ref -- the value obtained from the first subquery. In SQLAlchemy, this is effectively what I have now:
ct = aliased(classes.company)
at = aliased(classes.associative_table)
pt = aliased(classes.policy)
policy_id_ref = session.query(at.policy_id).\
filter(at.company_id == ct.company_id).\
label('policy_id_ref')
policy_default = session.query(pt.default).\
filter(pt.id == 'policy_id_ref').\
label('default')
query = session.query(ct.company_id,policy_id_ref,policy_default)
The pull from the "company" table works fine as does the first subquery that retrieves the "policy_id_ref" column. The problem is the second subquery that has to reference that "policy_id_ref" column. I don't know how to write its filter in such a way that it literally renders "policy_id_ref" in the resulting query, to match the label of the first subquery.
Suggestions?
Thanks in advance
You can write your query as
select(
Companies.company_id,
AssociativeTable.policy_id.label('policy_id_ref'),
Policy.default.label('policy_default'),
).select_from(
Companies,
).join(
AssociativeTable,
AssociativeTable.company_id == Companies.company_id,
).join(
Policy,
AssociativeTable.policy_id == Policy.id
)
but in case you need reference to label from subquery => use literal_column
from sqlalchemy import func, select, literal_column
session.query(
func.array_agg(
literal_column('batch_info'),
JSONB
).label('history')
).select_from(
select(
func.jsonb_build_object(
'batch_id', AccountingQueueBatch.id,
'batch_label', AccountingQueueBatch.label,
).label('batch_info')
).select_from(
AccountingQueueBatch,
)
)
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 have created a query with a subquery in Access, and cannot link it in Excel 2003: when I use the menu Data -> Import External Data -> Import Data... and select the mdb file, the query is not present in the list. If I use the menu Data -> Import External Data -> New Database Query..., I can see my query in the list, but at the end of the import wizard I get this error:
Too few parameters. Expected 2.
My guess is that the query syntax is causing the problem, in fact the query contains a subquery. So, I'll try to describe the query goal and the resulting syntax.
Table Positions
ID (Autonumber, Primary Key)
position (double)
currency_id (long) (references Currency.ID)
portfolio (long)
Table Currency
ID (Autonumber, Primary Key)
code (text)
Query Goal
Join the 2 tables
Filter by portfolio = 1
Filter by currency.code in ("A", "B")
Group by currency and calculate the sum of the positions for each currency group an call the result: sumOfPositions
Calculate abs(sumOfPositions) on each currency group
Calculate the sum of the previous results as a single result
Query
The query without the final sum can be created using the Design View. The resulting SQL is:
SELECT Currency.code, Sum(Positions.position) AS SumOfposition
FROM [Currency] INNER JOIN Positions ON Currency.ID = Positions.currency_id
WHERE (((Positions.portfolio)=1))
GROUP BY Currency.code
HAVING (((Currency.code) In ("A","B")));
in order to calculate the final SUM I did the following (in the SQL View):
SELECT Sum(Abs([temp].[SumOfposition])) AS sumAbs
FROM [SELECT Currency.code, Sum(Positions.position) AS SumOfposition
FROM [Currency] INNER JOIN Positions ON Currency.ID = Positions.currency_id
WHERE (((Positions.portfolio)=1))
GROUP BY Currency.code
HAVING (((Currency.code) In ("A","B")))]. AS temp;
So, the question is: is there a better way for structuring the query in order to make the export work?
I can't see too much wrong with it, but I would take out some of the junk Access puts in and scale down the query to this, hopefully this should run ok:
SELECT Sum(Abs(A.SumOfPosition)) As SumAbs
FROM (SELECT C.code, Sum(P.position) AS SumOfposition
FROM Currency As C INNER JOIN Positions As P ON C.ID = P.currency_id
WHERE P.portfolio=1
GROUP BY C.code
HAVING C.code In ("A","B")) As A
It might be worth trying to declare your parameters in the MS Access query definition and define their datatypes. This is especially important when you are trying to use the query outside of MS Access itself, since it can't auto-detect the parameter types. This approach is sometimes hit or miss, but worth a shot.
PARAMETERS [[Positions].[portfolio]] Long, [[Currency].[code]] Text ( 255 );
SELECT Sum(Abs([temp].[SumOfposition])) AS sumAbs
FROM [SELECT Currency.code, Sum(Positions.position) AS SumOfposition
FROM [Currency] INNER JOIN Positions ON Currency.ID = Positions.currency_id
WHERE (((Positions.portfolio)=1))
GROUP BY Currency.code
HAVING (((Currency.code) In ("A","B")))]. AS temp;
I have solved my problems thanks to the fact that the outer query is doing a trivial sum. When choosing New Database Query... in Excel, at the end of the process, after pressing Finish, an Import Data form pops up, asking
Where do you want to put the data?
you can click on Create a PivotTable report... . If you define the PivotTable properly, Excel will display only the outer sum.
