I have below query
select catid, cat_name, currency, count(is_reporting_category_sales.id) as total_sales,
sum(total_sales) as total_earning
from is_category
left join is_reporting_category_sales on is_category.catid = is_reporting_category_sales.category_id
join is_reporting_order on is_reporting_order.id = is_reporting_category_sales.order_id
group by catid, cat_name, currency
ORDER BY `is_category`.`cat_name` ASC
but this is returning only rows that are common in is_category and is_reporting_category_sales, is_reporting_order but I want to fetch all rows from is_category table. And if there is no order for the category then 0 as total_earning and total_sales.
