Question

I’m relatively new to coding and have tried searching for a solution, but am not entirely sure how to phrase my question. What would be simplest way to achieve the result I need, as detailed in the example that follows? I’m using MSSQL.

SELECT Unit, Quantity FROM SomeTable WHERE Parameter1 = 'x'

Gives me the result:

Unit | Quantity
---------------
a    | 10
b    | 10
c    | 10
a    | 10

This is the result I need:

Unit | Quantity
---------------
a    | 20
b    | 10
c    | 10

Any help would be greatly appreciated.

Answer 1

Adding a GROUP BY so do the trick for you.

SELECT Unit, Sum(Quantity)
FROM SomeTable
WHERE Parameter1 = 'x'
GROUP BY Unit
