In SQL Stuck trying to UPDATE a table column from the results of a COUNT
I am building up a table for statistical analysis of production data. I have extracted all the distinct cases, and constructed a count to find how many times each unique case appears in the table.
My issue comes when trying to UPDATE the table's "Number" column with the results from the COUNT
Here is the code I have so far.
TRUNCATE TABLE WeightData
INSERT INTO WeightData (WeightType,WeightIncrement)
SELECT DISTINCT OutboardWeightTable,OutboardAmount
FROM ProductionData
WHERE [Datetime] between '180821_150000' and '180822_000000' and (OutboardAmount > 0)
--UPDATE WeightData
--SET Number = (
SELECT COUNT(*)
FROM WeightData a
inner join ProductionData b
ON (a.WeightType = b.OutboardWeightTable) and (a.WeightIncrement = b.OutboardAmount)
WHERE [Datetime] between '180821_150000' and '180822_000000' and (OutboardAmount > 0)
GROUP BY a.WeightType,a.WeightIncrement
--)
I have commented out the lines that are not working, but when I try to run the query I get the following message. I have tried many different ways to do this but I feel this is my closes attempt.
Msg 512, Level 16, State 1, Procedure TestProcedure, Line 24 Subquery
returned more than 1 value. This is not permitted when the subquery
follows =, !=, <, <= , >, >= or when the subquery is used as an
expression.
When I run the code after commenting those lines, here is the table and the results screen.

I think you just want a correlated subquery:
UPDATE WeightData
SET Number = (SELECT COUNT(*)
FROM ProductionData pd
WHERE wd.WeightType = p.OutboardWeightTable and
wd.WeightIncrement = pd.OutboardAmount AND
pd.OutboardAmount > 0 AND
pd.[Datetime] between '180821_150000' and '180822_000000'
)
FROM WeightData wd;
I modified the b and p to pd and it works!! I have spent a shameful amount of time stuck on this thanks a lot!
