单个mysql查询中的多个计数

Question

如何在mysql中对同一个字段进行多次计数？ 单个计数的下面的代码工作正常

SELECT fruit, COUNT(DISTINCT site) AS `apple` FROM grocery where fruit like '%06201%'

但是，当我尝试这个但我得到语法错误

SELECT
    SUM(fruit like '%06201%') AS `apple`,
    SUM(fruit like '%02206%') AS `pears`,
FROM grocery

Answer 1

SELECT
    SUM(fruit like '%06201%') AS `apple`,
    SUM(fruit like '%02206%') AS `pears`,
                                        ^
                                        here
FROM grocery

你有两个commata，但你只需要一个。

Answer 2

在FROM之前删除额外的逗号

SELECT
    SUM(fruit like '%06201%') AS `apple`,
    SUM(fruit like '%02206%') AS `pears`
FROM grocery
