I am building a query which works perfectly fine until I try to GROUP BY tblWJC.WJCNo
Query:
SELECT
tblWJCItem.AddedDescription
,tblWJC.WJCPrefix + Convert(Varchar(10),tblWJC.WJCNo) AS OurRef
,tblWJCItem.MaterialName
,tblStockFamily.StockFamily
,tblWJCItem.WeightToSend
,tblWJC.DateCreated
,tblWJC.WJCStatusID
,CASE
WHEN tblWJC.WJCStatusID < 2 THEN 'Pre Production'
WHEN tblWJC.WJCStatusID < 4 THEN 'In Production'
WHEN tblWJC.WJCStatusID > 4 THEN 'Ready To Ship'
ELSE 'Awaiting Lab Results'
END AS [Status]
FROM
tblWJC
INNER JOIN
tblWJCItem ON tblWJC.WJCID = tblWJCItem.WJCID
INNER JOIN
tblStockFamily ON tblWJCItem.ProductFamilyID = tblStockFamily.StockFamilyID
INNER JOIN
tblCustomer ON tblWJC.CustomerID = tblCustomer.CustomerID
INNER JOIN
tblWJCStockStatus ON tblWJC.WJCStatusID = tblWJCStockStatus.WJCStockStatusID
WHERE
tblCustomer.CustomerName = 'ROLLS ROYCE'
AND tblWJCStockStatus.WJCStockStatus <> 'Stock Usage Confirmed'
GROUP BY
tblWJC.WJCNo
ORDER BY
tblStockFamily.StockFamily;
Can any one point out my mistake here? I am new to SQL Server, still learning by doing.
Thanks
This is common that you have a field aggregation error when you group a query by a field than you don't add an aggregate function on the fields that are part of your select statement. In your case, you're doing a group by the tblWJC.WJCNo column and then you are not aggregating your fields in the select statement.
SELECT tblWJCItem.AddedDescription
,tblWJC.WJCPrefix + Convert(Varchar(10),tblWJC.WJCNo) AS OurRef
,tblWJCItem.MaterialName
,tblStockFamily.StockFamily
,tblWJCItem.WeightToSend
,tblWJC.DateCreated
,tblWJC.WJCStatusID
,CASE WHEN tblWJC.WJCStatusID < 2 THEN 'Pre Production'
WHEN tblWJC.WJCStatusID < 4 THEN 'In Production'
WHEN tblWJC.WJCStatusID > 4 THEN 'Ready To Ship'
ELSE 'Awaiting Lab Results'
END AS [Status]
If you group by a field and you want to put other fields in the select statement, these fields should be either aggregated or included in the group by statement and that seems logical since if you group data by a field, the other fields should aggregated by the group by field in order to display them.
Here is a link that contains all the aggregation function in SQL Server:

I am new to SQL and I have the below tables
that I need to select and get the desired result below.
Try a query like below.
select
[Account Group] =AG.Name,
[Ledger Name] =AL.Name,
DR =SUM(CASE WHEN TT.Name='DR' THEN Amount ELSE NULL END),-- case based SUM expression
CR =SUM(CASE WHEN TT.Name='CR' THEN Amount ELSE NULL END)
from Account_Group AG
join Account_ledgers AL -- NOTE we have used INNER JOIN throughout
on AG.Id=AL.AccountGroupId
join Transactions T
on T.AccountLedgerId=AL.Id
join Transaction_Type TT
on TT.Id= T.TransactionTypeId
group by AG.Name,AL.Name -- Group by contains all the things we need in SELECT list
I need to join these two tables. I need to select occurrences where:
ex_head of_family_active = 1 AND tax_year = 2017
and also:
ex_head of_family_active = 0 AND tax_year = 2016
The first time I tried to join these two tables I got the warehouse data
dbo.tb_master_ascend AND warehouse_data.dbo.tb_master_ascend in the from clause have the same exposed names. As the query now shown below, I get a syntax error on the "where". What am I doing wrong? Thank you
use [warehouse_data]
select
parcel_number as Account,
pact_code as type,
owner_name as Owner,
case
when ex_head_of_family_active >= 1
then 'X'
else ''
end 'Head_Of_Fam'
from
warehouse_data.dbo.tb_master_ascend
inner join
warehouse_data.dbo.tb_master_ascend on parcel_number = parcel_number
where
warehouse_data.dbo.tb_master_ascend.tax_year = '2016'
and ex_head_of_family_active = 0
where
warehouse_data.dbo.tb_master_ascend.t2.tax_year = '2017'
and ex_head_of_family_active >= 1
and (eff_from_date <= getdate())
and (eff_to_date is null or eff_to_date >= getdate())
#marc_s I changed the where statements and updated my code however the filter is not working now:
use [warehouse_data]
select
wh2.parcel_number as Account
,wh2.pact_code as Class_Type
,wh2.owner_name as Owner_Name
,case when wh2.ex_head_of_family_active >= 1 then 'X'
else ''
end 'Head_Of_Fam_2017'
from warehouse_data.dbo.tb_master_ascend as WH2
left join warehouse_data.dbo.tb_master_ascend as WH1 on ((WH2.parcel_number = wh1.parcel_number)
and (WH1.tax_year = '2016')
and (WH1.ex_head_of_family_active is null))
where WH2.tax_year = '2017'
and wh2.ex_head_of_family_active >= 1
and (wh2.eff_from_date <= getdate())
and (wh2.eff_to_date is null or wh2.eff_to_date >= getdate())
I would use a CTE to get all your parcels that meet your 2016 rules.
Then join that against your 2017 rules on parcel ID.
I'm summarizing:
with cte as
(
select parcelID
from
where [2016 rules]
group by parcelID --If this isn't unique you will cartisian your results
)
select columns
from table
join cte on table.parcelid=cte.parcelID
where [2017 rules]
I have written a query that returns the list of all customers that have ever made a purchase with the company I work for. The person for whom I am getting the data would like to know if a specific criteria is true for any of these orders.
select L.ParentLocation,
[Number of Orders] = count(distinct(T.Order))
from Table1 L
join Table2 T
on L.Location = T.Location
group by L.ParentLocation
However, the issue is complicated because I am already grouping by ParentLocation, and each ParentLocation has many normal Locations. So I am counting the number of unique orders at the location level, then grouping them by the ParentLocation.
I want to return 'TRUE' in the query if a field 'OrderDesc' contains "Toys" in ANY of the orders by ANY of the Locations owned by a ParentLocation. Is there a way to do this?
NOTE: Table2 contains the OrderDesc column.
Thanks for reading!
select
L.ParentLocation,
[Number of Orders] = count(distinct(T.Order)),
has_toys = max(case when t.OrderDesc like '%toys%' then 'TRUE' else '' end)
from Table1 L
inner join Table2 T
on L.Location = T.Location
group by
L.ParentLocation
I have the below T-SQL CTE code where i'm trying to do some row grouping on four columns i.e Product, ItemClassification, Name & Number.
;WITH CTE_FieldData
AS (
SELECT
CASE(GROUPING(M.CodeName))
WHEN 0 THEN M.CodeName
WHEN 1 THEN 'Total'
END AS Product,
CASE(GROUPING(KK.ItemClassification))
WHEN 0 THEN KK.[ItemClassification]
WHEN 1 THEN 'N/A'
END AS [ItemClassification],
CASE(GROUPING(C.[Name]))
WHEN 0 THEN ''
WHEN 1 THEN 'Category - '+ '('+ItemClassification+')'
END AS [Name],
CASE(GROUPING(PYO.Number))
WHEN 0 THEN PYO.Number
WHEN 1 THEN '0'
END AS [Number],
ISNULL(C.[Name],'') AS ItemCode,
MAX(ISNULL(PYO.Unit, '')) AS Unit,
MAX(ISNULL(BT.TypeName, '')) AS [Water Type],
MAX(ISNULL(PYO.OrderTime, '')) AS OrderTime,
MAX(ISNULL(BUA.Event, '')) AS Event,
MAX(ISNULL(PYO.Remarks, '')) AS Remarks,
GROUPING(M.CodeName) AS ProductGrouping,
GROUPING(KK.ItemClassification) AS CategoryGrouping,
GROUPING(C.[Name]) AS ItemGrouping
FROM CTable C INNER JOIN CTableProducts CM ON C.Id = CM.Id
INNER JOIN MyData R ON R.PId = CM.PId
INNER JOIN MyDataDetails PYO ON PYO.CId = C.CId AND PYO.ReportId = R.ReportId
INNER JOIN ItemCategory KK ON C.KId = KK.KId
INNER JOIN Product M ON R.ProductId = M.ProductId
INNER JOIN WaterType BT ON PYO.WId = BT.WId
INNER JOIN WaterUnit BUA ON PYO.WUId = BUA.WUId
WHERE R.ReportId = 4360
GROUP BY M.CodeName, KK.ItemClassification, C.Name, PYO.Number
WITH ROLLUP
)
SELECT
Product,
[Name] AS Category,
Number,
Unit as ItemCode,
[Water Type],
OrderTime,
[Event],
[Comment]
FROM CTE_FieldData
Below are the issues/problems with the data being returned by the script above and they are the ones i'm trying to fix.
At the end of each ItemClassification grouping, i extra record is being added yet it does not exist in the table. (See line number 4 & 10 in the sample query results screenshot attached).
I want the ItemClassification grouping in column 2 to be at the beginning of the group not at the end of the group.
That way, ItemClassification "Category- (One)" would be at line 1 not the current line 5.
Also ItemClassification "Category- (Two)" would be at line 5 not the current line 11
Where the "ItemClassification" is displaying i would like to have columns (Number, ItemCode, [Water Type], [OrderTime], [Event], [Comment]) display null.
In the attached sample query results screenshot, those would be rows 11 & 5
The last row (13) is also unwanted.
I'm trying to understand SQL CTE and the GROUPING function but i'm not getting things right.
It looks like this is mostly caused by WITH ROLLUP and GROUPING. ROLLUP allows you to make essentially a sum line for your groupings. When you have WITH ROLLUP, it will give you NULL values for all of your non-aggregated fields in your select statement. You use GROUPING() in conjunction with ROLLUP to then label those NULL's as 'Total' or '0' or 'Category' as your query does.
1) Caused by GROUPING and ROLLUP. Take away both and this should be resolved.
2) Not sure what determines your groups and what would be defined as beginning or end. Order BY should suffice
3) Use ISNULL or CASE WHEN. If the Item Classification has a non null or non blank value, NULL each field out.
4) Take off WITH ROLLUP.
Is it possible in SQL to calculate the percentage of the 'StaffEntered' column's "Yes" values (case when calculated column) out of the grand total number of orders by that user (RequestedBy)? I'm basically doing this function now myself in Excel with a Pivot table, but thought it may be easier to build it into the query. Here is the existing sample SQL code:
Select
Distinct
RequestedBy = HStaff.Name,
AccountID = isnull(pv.AccountID, ''),
StaffEntered = Case When DictionaryItem2.Name like '%PLB%' Then 'Yes' Else 'No' end
FROM
[dbo].[HOrd] HOrd WITH ( NOLOCK )
left outer join HStaff HStaff with (nolock)
on HOrd.Requestedby_oid = HStaff.ObjectID
and HStaff.Active = 1
left outer join DictionaryItem DictionaryItem2 WITH (NOLOCK)
ON HSUser1.PreferenceGroup_oid = DictionaryItem2.ObjectID
AND DictionaryItem2.ItemType_oid = 98
Here is what I am doing in Excel currently with the query results, I have a pivot table and I am dividing the "Yes" values of the "StaffEntered" field out of the Grand Total number of entries for that specific "RequestedBy" user. Essentially Excel is doing the summarization and then I am doing a simple division calculation to obtain the percentage.
Thanks in advance!
You didn't provide a lot in the way of details but I think this should be pretty close to what you are looking for.
select HStaff.Name as RequestedBy
, isnull(pv.AccountID, '') as AccountID
, Case When DictionaryItem2.Name like '%PLB%' Then 'Yes' Else 'No' end as StaffEntered
, sum(Case When DictionaryItem2.Name like '%PLB%' Then 1 Else 0 end) / GrandTotal
From SomeTable
group by HStaff.Name
, isnull(pv.AccountID, '')
, GrandTotal
Giving the FROM part of your SQL Statement would allow us to create a more correct answer. This statement will get the totals of yes/no per HStaff name and add it to each detail record in your SQL statement:
WITH cte
AS ( SELECT HStaff.Name ,
SUM(CASE WHEN dictionaryItem2.Name LIKE '%PLB%' THEN 1
ELSE 0
END) AS YesCount ,
SUM(CASE WHEN dictionaryItem2.Name NOT LIKE '%PLB%'
THEN 1
ELSE 0
END) AS NotCount
FROM YourTable
GROUP BY HStaff.Name
)
SELECT HStaff.Name AS requestedBy ,
ISNULL(pv.AccountID, '') AS AccountID ,
CASE WHEN DictionaryItem2.Name LIKE '%PLB%' THEN 'Yes'
ELSE 'No'
END AS StaffEntered ,
cte.YesCount / ( cte.YesCount + cte.NotCount ) AS PLB_Percentage
FROM yourtable
INNER JOIN cte ON yourtable.Hstaff.Name = cte.NAME
