SQL Group By Modulo of Row Count
- by Alex Czarto
I have the following sample data:
Id Name Quantity
1 Red 1
2 Red 3
3 Blue 1
4 Red 1
5 Yellow 3
So for this example, there are a total of 5 Red, 1 Blue, and 3 Yellow. I am looking for a way to group them by Color, but with a maximum of 2 items per group (sorting is not important). Like so:
Name QuantityInPackage
Red 2
Red 2
Red 1
Blue 1
Yellow 2
Yellow 1
Any suggestions on how to accomplish this using T-SQL on MS-SQL 2005?
