I know SQL Server Pivot, but this time I think I will need something more complex then a simple pivoted value.
Here it is an SQL fiddle example.
So I have a table where I have maximum 3 rows for one startcity - endcity combination.
In a query I need to get these combinations in just one row, and I need just those combinations, where there are 3 rows.
Please advice,
You can do this as a crosstab like this.
with NumberedValues as
(
SELECT EndCity
, StartDate
, EndDate
, Price
, ROW_NUMBER() OVER(PARTITION BY StartCity, EndCIty ORDER BY StartDate) as RowNum
FROM [dbo].[BestPrice]
)
SELECT EndCity,
max(CASE WHEN RowNum = 1 THEN StartDate END) as StartDate1,
max(CASE WHEN RowNum = 1 THEN Enddate END) as EndDate1,
max(CASE WHEN RowNum = 1 THEN Price END) as Price1,
max(CASE WHEN RowNum = 2 THEN StartDate END) as StartDate2,
max(CASE WHEN RowNum = 2 THEN Enddate END) as EndDate2,
max(CASE WHEN RowNum = 2 THEN Price END) as Price2,
max(CASE WHEN RowNum = 3 THEN StartDate END) as StartDate3,
max(CASE WHEN RowNum = 3 THEN Enddate END) as EndDate3,
max(CASE WHEN RowNum = 3 THEN Price END) as Price3
FROM NumberedValues
group by EndCity

I have the following code which I'm using to transpose some data (see below); however, when running the code I received a 'Operand data type datetime2 is invalid for sum operator' error, which I believe is due to the fact the [RESULT_DT_TM] column has both date and time values. With the help from the outstanding contributors, I made what turns out to be a very simple code that removes the date from the [RESULT_DT_TM]:
select cast([RESULT_DT_TM] as time (0)) as [result_dt]
from ED_Vitals_Import_Master
I would like to include this code within the main query so I have use the new [result_dt] variable but am having trouble embedding it. Is it possible to do what I am seeking?
Select *
From (
Select a.[PT_FIN]
,B.*
From (Select *,RN=Row_Number() over (Partition By PT_FIN Order by [RESULT_DT_TM]) From ED_Vitals_Import_Master ) A
Cross Apply (values (concat('Time' ,RN),[RESULT_DT_TM])
,(concat('Weight' ,RN),[WEIGHT_RESULT])
,(concat('SysBp' ,RN),[SYSBP_RESULT])
,(concat('DiaBP',RN),[DIABP_RESULT])
,(concat('Temp' ,RN),[TEMPERATURE_RESULT])
,(concat('Oxy' ,RN),[OXYGEN_SAT_RESULT])
,(concat('Fio' ,Rn),[FIO2_RESULT])

Pivot (sum(Value) for Item in ([RESULT_DT_TM1],[Weight1],[Sysbp1],[DiaBP1], [Temp1], [Oxy1], [Fio1]

,[RESULT_DT_TM4],[Weight4],[Sysbp4],[DiaBP4], [Temp4], [Oxy4], [Fio4]
) ) pvt
Since you are mixing datatypes... perhaps a conditional aggregation would be more useful.
Example
Select a.[PT_FIN]
,[RESULT_DT_TM1] = max(case when RN=1 then [RESULT_DT_TM] end)
,[Weight1] = max(case when RN=1 then [Weight] end)
,[Sysbp1] = max(case when RN=1 then [Sysbp] end)
,[DiaBP1] = max(case when RN=1 then [DiaBP] end)
,[Temp1] = max(case when RN=1 then [Temp] end)
,[Oxy1] = max(case when RN=1 then [Oxy] end)
,[Fio1] = max(case when RN=1 then [Fio] end)
,[RESULT_DT_TM2] = max(case when RN=2 then [RESULT_DT_TM] end)
,[Weight2] = max(case when RN=2 then [Weight] end)
,[Sysbp2] = max(case when RN=2 then [Sysbp] end)
,[DiaBP2] = max(case when RN=2 then [DiaBP] end)
,[Temp2] = max(case when RN=2 then [Temp] end)
,[Oxy2] = max(case when RN=2 then [Oxy] end)
,[Fio2] = max(case when RN=2 then [Fio] end)

CodeDt CodeHeader Item Qty Type Remark Attachment
LK4-033502 RK-K-LK4-032438 IA01001023 2.00 TPR002 2 1.jpeg
LK4-033502RK RK-K-LK4-032438 IA01001023RK 2.00 NULL IA01001023 NULL
Above is my data from Sql server table (using 2008 R2). I want to make it one row only. Here is my expected result:
CodeDt CodeHeader Item NewItem Qty
LK4-033502 RK-K-LK4-032438 IA01001023 IA01001023RK 2.00
How can I achieve that? Here is the relation:
Row 1 Item = Row 2 Remark,
Row 1 Code DT = Row 2 CodeDt+'RK'
There are several solutions
1) Using JOIN. It assumes that Type field is null for rows with CodeDt+'RK'
select
a.CodeDt, a.CodeHeader, a.Item, b.Item, a.Qty
from
myTable a
join myTable b on a.Item = b.Remark
where
a.Type is not null
2) Conditional aggregation
select
max(case when rn = 1 then CodeDt end)
, CodeHeader
, max(case when rn = 1 then Item end)
, max(case when rn = 2 then Item end)
, max(case when rn = 1 then Qty end)
from (
select
*, rn = row_number() over (partition by CodeHeader order by CodeDt)
from
myTable
) t
group by CodeHeader
I have the following data on a MSSQL Server:
Item No_ Unit Of Measure Qty Per Base UoM Rounding Precision
000001 PIECE 1 1.0
000001 PALLET 100 1.0
000001 BOX 12 1.0
000002 KG 1 1.0
000002 TON 1000 0.001
I am trying to get the following output:
Item No_ UoM1 Qty pb UoM1 RP1 UoM2 Qty pb UoM2 RP2 UoM3 Qty pb UoM3 RP3
000001 PIECE 1 1.0 PALLET 100 1.0 BOX 12 1.0
000002 KG 1 1.0 TON 1000 0.0001 NULL NULL NULL
I tried achieving this using the PIVOT operator but it does not seem te be correct.
What is the correct way to achieve my desired output?
For trully generic solution you need to use Dynamic-SQL.
But you say you want starting point, so I give you one. You can use:
LiveDemo
WITH cte AS
(
SELECT *, ROW_NUMBER() OVER(PARTITION BY Item_No_ ORDER BY (SELECT 1)) AS rn
FROM #mytable
)
select Item_No_,
max(case when rn = 1 then Unit_Of_Measure end) UoM1,
max(case when rn = 1 then Qty_Per_Base_UoM end) [Qty pb UoM1],
max(case when rn = 1 then Rounding_Precision end) RP1,
max(case when rn = 2 then Unit_Of_Measure end) UoM2,
max(case when rn = 2 then Qty_Per_Base_UoM end) [Qty pb UoM2],
max(case when rn = 2 then Rounding_Precision end) RP2,
max(case when rn = 3 then Unit_Of_Measure end) UoM3,
max(case when rn = 3 then Qty_Per_Base_UoM end) [Qty pb UoM3],
max(case when rn = 3 then Rounding_Precision end) RP3,
max(case when rn = 4 then Unit_Of_Measure end) UoM4,
max(case when rn = 4 then Qty_Per_Base_UoM end) [Qty pb UoM4],
max(case when rn = 4 then Rounding_Precision end) RP4
from cte
group by Item_No_;
The point is that if your number of units is known in advance you can create hardcoded columns from 1 .. n.
For more info search Dynamic Pivot multiple columns. It is achievable, but first try to crack this solution.
I have a Query that selects Election data. Of course, when you start an election, there are 0 votes input for all candidates. But gradually, votes get entered. In order to get the percentage to output from the results, I took, number of votes multiplied by 100 then divided by total votes and I got my percentage.
Problem- once my query runs for the xml path, there is an error written in the top line of the xml document, "Divide by Zero error encountered". In order to bypass this, I just commented out the divide lines, but I would not like to do that. I figured, if I waited until there was a race that had votes in each field, I would then un-comment that line of code and let it output the percentage of only that race....until ALL races had at least some votes within them.
Here is my sql code:
:XML ON
select
max(case when seqnum = 1 then title1 end) as title1,
max(case when seqnum = 1 then [precinct percent] end) as PrecinctPercent,
max(case when seqnum = 1 then [candidate num] end) as WinnerNum,
max(case when seqnum = 1 then Votes end) as WinningVotes,
max(case when seqnum = 1 then party end) as WinningParty,
max(case when seqnum = 1 then leader end) as Winner,
max(case when seqnum = 1 then CAST(winner AS tinyint) end) as WinnerSelected,
max(case when seqnum = 1 then ((Votes * 100) / ([total vote])) end) as WinnerPercent,
max(case when seqnum = 2 then [candidate num] end) as LoserNum,
max(case when seqnum = 2 then Votes end) as LosingVotes,
max(case when seqnum = 2 then party end) as LosingParty,
max(case when seqnum = 2 then leader2 end) as Loser,
max(case when seqnum = 2 then ((Votes * 100) / ([total vote])) end) as LoserPercent,
max(case when seqnum = 2 then CAST(winner AS tinyint) end) as LoserSelected,
max(case when seqnum = 3 then title1 end) as title1,
max(case when seqnum = 3 then [precinct percent] end) as PrecinctPercent,
max(case when seqnum = 3 then [candidate num] end) as WinnerNum,
max(case when seqnum = 3 then Votes end) as WinningVotes,
max(case when seqnum = 3 then ((Votes * 100) / ([total vote])) end) as WinnerPercent,
max(case when seqnum = 3 then party end) as WinningParty,
max(case when seqnum = 3 then [first name]+ ' ' + [last name] end) as Winner,
max(case when seqnum = 3 then CAST(winner AS tinyint) end) as WinnerSelected,
max(case when seqnum = 4 then [precinct percent] end) as PrecinctPercent,
max(case when seqnum = 4 then [candidate num] end) as LoserNum,
max(case when seqnum = 4 then Votes end) as LosingVotes,
max(case when seqnum = 4 then ((Votes * 100) / ([total vote])) end) as LoserPercent,
max(case when seqnum = 4 then party end) as LosingParty,
max(case when seqnum = 4 then [first name]+ ' ' + [last name] end) as Loser,
max(case when seqnum = 4 then CAST(winner AS tinyint) end) as LoserSelected

) rc
group by rc.[race number]
FOR XML PATH ('ELECTION'), ROOT('root')
Is there a way I can have the select statement just "IGNORE" any fields that contain 0. Or choose to omit those that do contain 0 votes.
The total number of votes are being selected from the table "[RACE CANDIDATES]" if that helps. Hope it all makes sense.
Any input would be greatly appreciated.
Thanks All!
You can either put in a where in the sub select
WHERE r.[total vote] != 0
or you could use a case statment
CASE WHEN r.[total vote] = 0 THEN 0 ELSE Votes / r.[total vote] END
I'm using MS SQL 2005 and I have created a CTE query to return values from the last two records. I then use this to find the delta of two figures returned. I have a working query of sorts but
I'm having problems getting anything other than the delta figure.
here is my query:
;with data as(
SELECT
NetObjectID,
RawStatus,
RowID,
rn
from(
SELECT
CustomPollerAssignmentID AS NetObjectID,
RawStatus,
RowID,
row_number() over(order by DateTime desc)as rn
FROM CustomPollerStatistics_Detail
WHERE
(CustomPollerAssignmentID='a87f531d-4842-4bb3-9d68-7fd118004356')
) x where rn<=2
)
SELECT
case when
max(case rn when 1 then RawStatus end) > max(case rn when 2 then RawStatus end)
then
max(case rn when 1 then RawStatus end) - max(case rn when 2 then RawStatus end)
else
max(case rn when 2 then RawStatus end) - max(case rn when 1 then RawStatus end)
end as Delta
from data having
(SELECT
case when
max(case rn when 1 then RawStatus end) > max(case rn when 2 then RawStatus end)
then
max(case rn when 1 then RawStatus end) - max(case rn when 2 then RawStatus end)
else
max(case rn when 2 then RawStatus end) - max(case rn when 1 then RawStatus end)
end
from data) >= 1
What I'm after is to get the Delta & NetObjectID returned. Each time I try, I get errors.
data.NetObjectID is invalid in the select list because it is not contained in either an aggregate function or the group by clause.
If I try adding group by etc.. to the end of the query I get further error complaining about the word 'group'.
I'm relatively new to SQL and I am picking things up as I go. Any help would be gratefully received.
see if something like this will work.
;with data as
(
SELECT
NetObjectID,
RawStatus,
RowID,
rn
from
(
SELECT
CustomPollerAssignmentID AS NetObjectID,
RawStatus,
RowID,
row_number() over(order by DateTime desc)as rn
FROM CustomPollerStatistics_Detail
WHERE
(
CustomPollerAssignmentID='a87f531d-4842-4bb3-9d68-7fd118004356'
)
) x
where rn<=2
)
select
NetObjectID,
max(RawStatus)-min(RawStatus) as Delta
from data
group by NetObjectID
Sorry, I'm very new here and I'm unsure of CTE queries, however it looks like after you define Data, you are selecting case ... as Delta FROM.... Meaning you only have Delta in your select statement. Again, sorry if I'm way off base.
