报表分组 sql 书写求教

This topic created in 2029 days ago, the information mentioned may be changed or developed.

做一个类似下面链接的报表，要求列行均能动态选择字段分组，还要小计总计，排序。目前有这样一个困难，对于列分组，sql 里直接 select sum(fee) fee from xx group by column1，column2...with rollup，sql 结果集只会显示有值的行，比如 column1，column 分别都有 2 个状态 0 和 1，但只有 column1=0 和 column2=1 有记录，我现在需要一个 sql 不仅可以查出 column1=0 和 column2=1 的记录，还要查出 column1=0/1，column2=0/1 所有 4 个组合的记录，没有值的记录直接赋 0

SELECT IFNULL(SUM(a.fee), 0) fee, b.column1, b.column2
FROM xx a RIGHT JOIN (SELECT 0 AS column1, 0 AS column2) b
ON a.column1=b.column1 AND a.column2=b.column2
GROUP BY a.column1, a.column2
UNION ALL
SELECT IFNULL(SUM(a.fee), 0) fee, b.column1, b.column2

@echoe sql 符合要求，首先感谢写这么一段，而且还要建表什么挺繁琐的，感谢，就是字段状态值多的话是不是就不太适用了，sql 要写太长了，而且这边是要求可以动态选择字段分组的，想想还是挺麻烦的
