Question

I have 2 queries:

SELECT p.assetid, 
p.TagId, 
SUM(CASE WHEN p.isrepeat = 1  then 1 else 0 END) as 'Repeats',
SUM(CASE WHEN p.isrepeat = 0  then 1 else 0 END) as 'Non-Repeats',
CAST(SUM(CASE WHEN p.isrepeat =1 then 1 else 0 END) as DECIMAL)/COUNT(*)as 'Percent of Repeats'
from POSITION p
group by p.tagid, p.assetid
order by 1

and

SELECT p.AssetID, p.tagid, COUNT(*)
from POSITION p,
TEMP t
where t.beginning_X = p.X
and t.beginning_Y = p.y
and p.isrepeat = 1
and t.AssetID = p.AssetID
and t.Total_Distance_Traveled > 1
group by p.AssetID, p.tagid
order by 1

I’d like to combine their output into one table of results with the following columns:

AssetID,
TagID, 
Repeats (from the first query),
Non-Repeats (from the first query),
% of Repeats (from the first query),
Calc1 (difference of repeats in first query and count result from second query, grouped by asset id),
Calc1% (Calc1 result/repeats from the first query, grouped by assetid),
Calc2 (count result from the second query, grouped by assetid)
Cacl2%(Calc2 result/repeats from the first query, grouped by assetid)

I have started by creating a temp table to hold the results, and I can successfully insert the first query’s results, but I can’t figure out how to update the table with the second query and compute the percentage columns too. How can I get this to work?

You can do this using one query, see below

;WITH CTE AS (
SELECT 
--q1
p.assetid, 
p.TagId, 
SUM(CASE WHEN p.isrepeat = 1  then 1 else 0 END) as 'Repeats',
SUM(CASE WHEN p.isrepeat = 0  then 1 else 0 END) as 'Non-Repeats',
CAST(SUM(CASE WHEN p.isrepeat =1 then 1 
         else 0 END) as DECIMAL)/COUNT(*)as 'Percent of Repeats',

--q2
COUNT(t.AssetID) CNT2,

from POSITION p
LEFT OUTER JOIN TEMP t ON t.beginning_X = p.X 
                       and t.beginning_Y = p.y and t.AssetID = p.AssetID
                       AND p.isrepeat = 1 and t.Total_Distance_Traveled > 1

group by p.tagid, p.assetid
)

SELECT
Assetid, TagId, Repeats, Non-Repeats, [Percent of Repeats],
(repeats - cnt2) calc1, ((repeats - cnt2)/repeats [Per calc1],
(cnt2) calc2, (cnt2/repeats) [Per calc2]
FROM CTE
