Insert values in temp table form same table and different variables - sql-server

Question

I have this code, that works, but I want to insert in the temp table the same values (DateTime and Value) from another variable (UBB_PreT_Line_LA.If_TotalInFeddWeight) present in the same table ([Runtime].[dbo].[History]). Then, I show the result in SQL Report Builder 3.0 in a table.
SET NOCOUNT ON
DECLARE #fechaItem DATETIME;
DECLARE #fechaFinTotal DATETIME;
SET #fechaItem = DateAdd(hh,7,#Fecha)
SET #fechaFinTotal = DateAdd(hh,23,#Fecha)
SET NOCOUNT OFF
DECLARE #tblTotales TABLE
(
VALOR_FECHA DATETIME,
VALOR_VALUE float
)
WHILE #fechaItem < #fechaFinTotal
BEGIN
DECLARE #fechaFin DATETIME;
SET #fechaFin = DATEADD(minute, 15, #fechaItem );
INSERT INTO #tblTotales
SELECT
MAX( [DateTime] ),
MAX( [Value] )
FROM [Runtime].[dbo].[History]
WHERE
[DateTime] >= #fechaItem
AND [DateTime] <= #fechaFin
AND (History.TagName='UBB_PreT_Belt_PF101A.Time_Running')
SET #fechaItem = #fechaFin;
END
SELECT TOP 64 VALOR_FECHA as Fecha,VALOR_VALUE as Valor
FROM #tblTotales
order by Valor ASC
What I want, is to join in a single query the result I get in these two tables, with the same query in which only the variable that is queried changes.
The purpose is to create a unique Dataset in Report Builder to display in a single table, the data of the two tables of the image. The 15 minute interval is because I just want to show the variation of the values every 15 minutes.

I have modified the code (Image_02), and with the Query Designer of the Report Builder I have obtained what is shown in the Image_03. The final goal would be to have the data of the second variable, in two more columns on the right (Fecha_Ton and Valor_Ton). How can I do it?

If I've understood your question correctly, I think that this query replaces your code entirely (and adds the second value):
declare #sample table (Datetime datetime not null, Value int not null,
TagName varchar(50) not null)
insert into #sample (DateTime, Value, TagName) values
('2018-08-16T10:14:00',6,'UBB_PreT_Belt_PF101A.Time_Running'),
('2018-08-16T10:08:00',8,'UBB_PreT_Belt_PF101A.Time_Running'),
('2018-08-16T10:23:00',7,'UBB_PreT_Belt_PF101A.Time_Running'),
('2018-08-16T10:07:00',7,'UBB_PreT_Line_LA.If_TotalInFeddWeight')
declare #Fecha datetime
set #Fecha = '20180816'
select
MAX(DateTime),
MAX(CASE WHEN TagName='UBB_PreT_Line_LA.If_TotalInFeddWeight' THEN Value END) as Fed,
MAX(CASE WHEN TagName='UBB_PreT_Belt_PF101A.Time_Running' THEN Value END) as Running
from
#sample
where
DateTime >= DATEADD(hour,7,#Fecha) and
DateTime < DATEADD(hour,23,#Fecha) and
TagName in ('UBB_PreT_Line_LA.If_TotalInFeddWeight',
'UBB_PreT_Belt_PF101A.Time_Running')
group by DATEADD(minute,((DATEDIFF(minute,0,DateTime)/15)*15),0)
order by MAX(DateTime) asc
Results:
Fed Running
----------------------- ----------- -----------
2018-08-16 10:14:00.000 7 8
2018-08-16 10:23:00.000 NULL 7
(You may want two separate dates following the same pattern using CASE as the values)
You shouldn't be building your data up row by agonising row1, you should find as way (such as that above) to express what the entire result set should look like as a single query. Let SQL Server itself decide whether it's going to do that by searching through the rows in date order, etc.
1There may be circumstances where you end up having to do this, but first exhaust any likely set-based options first.
