[英]SQL count each distinct value in column and add name from another table where the ID matches
[英]getting distinct column name and count when based on another table
我有以下查询:
select cc.category from companies c
left join categories cc on c.category_id = cc.category_id
where company_title like '%gge%';
返回具有重复行的类别。 我需要的是获取不同的类别,并带有该类别的准确总数,例如:
类别名称| XXX(其中XXX是计数)
有人可以帮忙吗?
使用此查询代替:
select distinct cc.category,
count(cc.category) as totalCategoryCount
from companies c
left join categories cc on c.category_id = cc.category_id
where company_title like '%gge%'
group by cc.category
