[英]SUM of grouped group in MS Access SQL query
I have a table with 6 columns:我有一个有 6 列的表:
ID_flower | Name | Price | Flower color | Flowering period | Pot sizes
----------+-----------------------------+-------+--------------+------------------+----------
65 | Anemone japonica Wirbelwind | 10 | white | VII-IX | 11x11x11
71 | Anemone nemorosa Rosea | 5 | pink | III-IV | 9x9x9
73 | Asphodeline lutea | 8 | yellow | VI | 9x9x9
I want to group them by pot sizes, and sum this by pot sizes in MS Access query:我想按锅尺寸对它们进行分组,并在 MS Access 查询中按锅尺寸求和:
Pot sizes | Number of flowers
----------+------------------
11x11x11 | 1
9x9x9 | 2
Do you just want aggregation?你只是想要聚合吗?
select pot_size, count(*)
from mytable
group by pot_size
