Assert different conditions on fields from multiple tables - sql-server

Let's say I have a dimension and a fact table:
SELECT
LAST_DAY(TO_Date((f.Date),'MON-YYYY')) "MonthYear",
f.Region,
d.Formula as "Molecule",
d.product_name,
d.supplier.
SUM(f.Sales) as "Sales",
SUM(f.ext_units) as "ext_Units",
SUM(f.units) "Units",
SUM(f.ext_units) / SUM(f.units) as "Product_units"
CASE
WHEN d.Formula = 'ABC:CBA' THEN 'ABC'
WHEN d.Formula = 'DEF-FED' THEN 'DEF'
WHEN d.Formula = 'xyz;zyx' THEN 'xyz'
ELSE d.Formula
END AS "Molecule"
FROM Fact.Sales f
INNER JOIN DM_Product d on f.P-Code = d.P-Code
WHERE
f.Region = 'Mars'
AND d.Supplier = 'Simpsons'
AND d.Formula in ('ABC','DEF','GHI','JKL','BDHJK',
'FGL','MNP','RSTU', 'KCL', 'xyz', 'UWX',
'xyz;zyx', 'DEF-FED', 'ABC:CBA')
GROUP BY f.Date,
f.Region,
d.Formula,
d.product_name,
d.supplier
so, basically what I intend to do is to get all these Molecules from the Product Dimension table and find their relevant sales. but the puzzle is I have two different set of conditions:
to look into to all the two syllabuses formulas and aggregate them with equivalent one syllabi formula to find aggregate sales.
Find "Product_units" using SUM(f.ext_units) / SUM(f.units) as per my code.
(f.units) does have 0 values.
As I put for the 1st condition, I used CASE WHEN and it works perfect to find the 2 syllabuses formulas and plug them to relevant 1 syllabi formula but for the second condition that I need to know how to make sure that f.units <> 0 that is checking if SUM(f.units) <> 0 THEN SUM(f.ext_units) /SUM(f.units) ELSE 0 ?

Return Parts of an Array in Postgres

I have a column (text) in my Postgres DB (v.10) with a JSON format.
As far as i now it's has an array format.
Here is an fiddle example: Fiddle
If table1 = persons and change_type = create then i only want to return the name and firstname concatenated as one field and clear the rest of the text.
Output should be like this:
id table1 did execution_date change_type attr context_data
1 Persons 1 2021-01-01 Create Name [["+","name","Leon Bill"]]
1 Persons 2 2021-01-01 Update Firt_name [["+","cur_nr","12345"],["+","art_cd","1"],["+","name","Leon"],["+","versand_art",null],["+","email",null],["+","firstname","Bill"],["+","code_cd",null]]
1 Users 3 2021-01-01 Create Street [["+","cur_nr","12345"],["+","art_cd","1"],["+","name","Leon"],["+","versand_art",null],["+","email",null],["+","firstname","Bill"],["+","code_cd",null]]
Disassemble json array into SETOF using json_array_elements function, then assemble it back into structure you want.
select m.*
, case
when m.table1 = 'Persons' and m.change_type = 'Create'
then (
select '[["+","name",' || to_json(string_agg(a.value->>2,' ' order by a.value->>1 desc))::text || ']]'
from json_array_elements(m.context_data::json) a
where a.value->>1 in ('name','firstname')
)
else m.context_data
end as context_data
from mutations m
modified fiddle
(Note:
utilization of alphabetical ordering of names of required fields is little bit dirty, explicit order by case could improve readability
resulting json is assembled from string literals as much as possible since you didn't specified if "+" should be taken from any of original array elements
the to_json()::text is just for safety against injection

Exclude value from query where already returned in rows above

I am writing a query which will be used to populate a report used for putting away stock in a warehouse.
The report has 3 parameters, a source stock location, source bin number and a destination stock location.
The stock will be currently held in source stock location and bin number.
The destination stock location is where the stock needs to be moved to.
Each Variant has a default bin number in each stock location.
Multiple variants can have the same default bin number.
Bin numbers may not be alphabetical around the warehouse, and so each bin number is assigned a walk route, as the most efficient walking route around the warehouse.
The report will look at the default bin number associated with the item in the destination stock location, and if empty, offer that as the put away suggestion.
If the default bin number is not empty, it will look for the next available empty bin in the destination stock location (where walk route is higher than default bin), and then offer that as the put away suggestion.
The query works fine, and does exactly that, however it is reporting the same bin as previous "NextBinNo" suggestions in rows above.
How can I get the OUTER APPLY NextBinNo to filter out any previously suggested bins in higher rows of data? Also if two items have the same default bin number, it should use the NextBinNo for the second row with this default bin no.
My current query:
Select
row_number() Over(Order by DestSL.sl_id) as RowNo,
Stock_location.sl_name,
bin_number.bn_bin_number,
variant_detail.vad_variant_code,
variant_detail.vad_description,

isnull(DestDefaultBinQty.BinQty,0) as QtyInDefaultBin,
NextBinNo.NextBinNo as 'NextBinNo',
NextBinNo.NextWalkRoute as 'NextBinWalkRoute',
isnull(NextBinNo.BinQty,0) as 'NextBinQty',
case when DestDefaultBin.bn_bin_number is null
then 'Not Stocked in This Location'
Else
case when isnull(DestDefaultBinQty.BinQty,0) > 0
then
case when NextBinNo.NextBinNo is NULL
then 'No Free Bin'
Else NextBinNo.NextBinNo
End
Else DestDefaultBin.bn_bin_number
End
End as 'Put Away Destination'

and transaction_type.tt_transaction_type = 'IN' and transaction_Type.tt_update_current_qty = 1
and stock_location.sl_id = #SourceStockLoc and bin_number.bn_id = #SourceBinNo
You can see my current results below:
Row2 is using the NextBinNo as the default bin has stock.
Row3 is also suggesting using AA08A2 as the next bin.
Row 6 is currently suggesting AA01A2 but that has already been suggested in Row1.
Just to answer this, in the end I could not achieve what I wanted directly in SQL.
The data is ultimately being returned to a report writer which can run Visual Basic code.
I had to execute the NextBinNo sub query separately in VB.
In VB I can define a string which contains a list of all the "used" bin numbers and so on each row this is referenced in the WHERE of the query to check it has not been used in a row above.
I could then return this value as a new column dynamically inserted in the dataset at run time.

case statement filter in MDX query

I want to write the following T SQL query in MDX
Select count(bugs),priority from table
where
Case when priority =1 then startdate< dateadd(dd,-7,getdate())
when priority =2 then startdate< dateadd(dd,-14,getdate())
end
group by priority
Tried the following but not working
WITH MEMBER [Measures].CHECKING
AS
CASE [Item].[ startdate].CurrentMember
WHEN [Item].[ Priority].&[1] THEN [Item].[startdate]<DATEADD(DAY,-7,NOW())
WHEN [Item].[ Priority].&[2] THEN [Item].[startdate]<DATEADD(DAY,-14,NOW())
END
SELECT
NON EMPTY{[Measures].[Count], [Measures].CHECKING }ON COLUMNS
,NON EMPTY{([Item].[ Priority].[ Priority].ALLMEMBERS )}
I am new to MDX queries, any suggestions on how to approach this please..
Your CASE logic has a basic problem. The statement cannot result in a condition. It can only result in a value that you then compare to something else.
To take your tSQL example, I think it should read more like this:
Select count(bugs),priority from table
where
1 = Case when priority = 1 and startdate< dateadd(dd,-7,getdate()) Then 1
when priority = 2 and startdate< dateadd(dd,-14,getdate()) then 1
else 0 end
group by priority
A cleaner way to write this would be to skip the CASE altogether.
Select count(bugs),priority from table
where
(priority = 1 and startdate< dateadd(dd,-7,getdate()))
or
(priority = 2 and startdate< dateadd(dd,-14,getdate()))
group by priority
I am assuming the following:
Your startdate hierarchy is an attribute hierarchy, not a user hierarchy and
the current day is its last member.
Then the following MDX should deliver what you want:
SELECT
{ [Measures].[Count] }
ON COLUMNS
,
{ [Item].[ Priority].&[1], [Item].[ Priority].&[2] }
ON ROWS
FROM (
SELECT ({ [Item].[ Priority].&[1] }
*
([Item].[ startdate].[ startdate].Members
- Tail([Item].[ startdate].[ startdate].Members, 7)
)
)
+
({ [Item].[ Priority].&[2] }
*
([Item].[ startdate].[ startdate].Members
- Tail([Item].[ startdate].[ startdate].Members, 14)
)
)
ON COLUMNS
FROM [yourCube]
)
Your code [Item].[startdate]<DATEADD(DAY,-7,NOW()) does not work in MDX for several reasons: firstly, [Item].[startdate] is a hierarchy, and hence cannot be compared using <. Secondly, even if you would re-state it as [Item].[startdate].CurrentMember < DATEADD(DAY,-7,NOW()), you would have a member on the left side of the <, and a date , i. e. a value, on the right side. One of the important things to keep in mind with MDX are the different types of objects: Hierarchies, levels, members, tuples, sets. And all these are not values. You do not just have columns like in SQL.

Retriving data from different tables depending on value in a column

Please pardon me if this question has been asked before, but I simply don't have enough vocabulary to search for what I need as a novice in data bases.
I am using SQL server 2008.
I have a table tblPDCDetails with several columns. One of the columns PDCof holds values :
"A"(for applicant),
"C" for coapplicant,
"G" (for Guarantor).
Another column HolderID holds uniqueid (of holder).
The PDCHolders reside in their respective tables: Applicants in tblApplBasicDetails, CoApllicants in their own table and so on.
Now what I need is how should I retrive the names of holders from their respective tables, depending on the value in PDCof column.
Can I do it at all?
If no how should I work around this?
This should do:
SELECT A.*,
COALESCE(B.Name,C.Name,D.Name) Name
FROM dbo.tblPDCDetails A
LEFT JOIN dbo.tblApplBasicDetails B
ON A.HolderID = B.HolderID
AND A.PDCof = 'A'
LEFT JOIN dbo.tblCoApplBasicDetails C
ON A.HolderID = C.HolderID
AND A.PDCof = 'C'
LEFT JOIN dbo.tblGuarantorlBasicDetails D
ON A.HolderID = D.HolderID
AND A.PDCof = 'G'
The other option is to use a case switch:
Select case Main.PDCof
when 'A' then (select HolderID from Applicants where main.value = value)
when 'C' then (select HolderID from CoApplicants where main.value = value)
when 'G' then (select HolderID from Guarantor where main.value = value)
end
,main.*
from tblPDCDetails main
Depends on whether you run this a few times a day, or a few thousand times an hour

Need to use information from one qry to dictate an action on another

Ok so this is going to sound a little complicated. I want to somehow put some kind of function that will divide a table value by two when its Policy number matches up with a policy number in another table.
Here is the query where I want that functions
SELECT
qryReinsuranceDPA1_izzy.POLICY_NO,
qryReinsuranceDPA1_izzy.PHASE_CODE,
qryReinsuranceDPA1_izzy.SUB_PHASE_CODE,
qryReinsuranceDPA1_izzy.SchedNP,

Sum(qryReinsuranceDPA1_izzy.SumOfPUA_FACE) AS SumOfSumOfPUA_FACE,
Sum(qryReinsuranceDPA1_izzy.SumOfOYT_FACE) AS SumOfSumOfOYT_FACE, TotalDPA = sum(case when qryReinsuranceDPA1_izzy.[SumOfNetDefExtraAdj] Is Null then qryReinsuranceDPA1_izzy.[SumOfNetDefPremiumAdj] else qryReinsuranceDPA1_izzy.[SumOfNetDefPremiumAdj] +qryReinsuranceDPA1_izzy.[SumOfNetDefExtraAdj] end),

qryReinsuranceDPA1_izzy.PAID_TO_DATE,
qryReinsuranceDPA1_izzy.VAL_DATE,
qryReinsuranceDPA1_izzy.ISSUE_DATE
GO
and this is the qry that contains the policy numbers that I want divided by 2 in the above qry.
SELECT
qryReinsuranceDPA1.POLICY_NO,
qryReinsuranceDPA1.PHASE_CODE,
qryReinsuranceDPA1.SUB_PHASE_CODE,
qryReinsuranceDPA1.ProdType,
TotalDPA = Sum(case when [SumOfNetDefExtraAdj] Is Null then [SumOfNetDefPremiumAdj] else [SumOfNetDefPremiumAdj] + SumOfNetDefExtraAdj end),
Sum(1) AS Expr1
FROM qryPolicyListforNYDefPRemAsset_Re RIGHT JOIN qryReinsuranceDPA1
ON
qryReinsuranceDPA1.POLICY_NO = qryPolicyListforNYDefPRemAsset_Re.POLICY_NO AND
qryReinsuranceDPA1.PHASE_CODE= qryPolicyListforNYDefPRemAsset_Re.PHASE_CODE AND
qryReinsuranceDPA1.SUB_PHASE_CODE = qryPolicyListforNYDefPRemAsset_Re.SUB_PHASE_CODE
GROUP BY qryReinsuranceDPA1.POLICY_NO,
qryReinsuranceDPA1.PHASE_CODE,
qryReinsuranceDPA1.SUB_PHASE_CODE,
qryReinsuranceDPA1.ProdType
HAVING (((Sum(1))<>1))
GO
quick example. Say that the Policy number 064543200 is located in the results of that second qry. I then want the number located in first qry in Total DPA assosciated with that Policy number to be divided by 2.
If this is still confusing please let me know and I will try to explain better. Both are views.
