在單個mysql查詢中多次計數

Question

如何在mysql中對同一個字段進行多次計數？下面的一個計數的代碼工作正常

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

然而，當我嘗試了這一點，但我得到的語法錯誤

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 

你有兩個commata，但你只需要一個。

前FROM

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