Question

My table called lets say “table1” looks as follows:

Area | Owner | Numberid | Average

1200 | Fed_G | 998 | 1400

1220 | Priv | 1001 | 1600

1220 | Local_G | 1001 | 1430

1220 | Prov_G | 1001 | 1560

1220 | Priv | 1674 | 1845

1450 | Prov_G | 1874 | 1982

Ideally what I would like to do is sum a few rows in the average column if:
1. they have the same numberid (lets say three rows all had a numberid=1000 then they would have their average added together)
2.Area=1220

Then take that and append it to the existing table, while setting the Owner field equal to “ALL”.

I just started working with Access so I’m not really sure how to do this, this is my horrible attempt:

SELECT ind.Area, ind.Owner, ind.numberid, 
(SELECT SUM([Average]) FROM   [table1] 
WHERE [numberid]=ind.numberid) AS Average
FROM [table1] AS ind
WHERE (((ind.numberid)>="1000" And (ind.numberid)<"10000") AND ((ind.Area)="1220"))

Can anyone guide me through what I should do? I’m not used to sql syntax.

I tried to use “ind” as a variable to compare to.

So far it gives me column names but no output.

Answer 1

I’m still unsure whether I understand what you want. So I’ll offer you this query and let you tell us if the result is what you want or how it differs from what you want.

SELECT
    t.Area,
    'ALL' AS Owner,
    t.Numberid,
    Sum(t.Average) AS SumOfAverage
FROM table1 AS t
GROUP BY t.Area, 'ALL', t.Numberid;

Using your sample data, that query gives me this result set.

Area Owner Numberid SumOfAverage
1200 ALL        998         1400
1220 ALL       1001         4590
1220 ALL       1674         1845
1450 ALL       1874         1982
