mysql - 两列 SQL 中出现频率最高的值

Question

我试图找出分组中表格中出现次数最多的值。这是针对 SQL 的

Part | location | PartDesc
-----+----------+-------------
A    | 2        | Part A
A    | 2        | Part A
A    | 2        | Part A
A    | 1        | Part A
A    | 1        | Part A
B    | 1        | Part B
B    | 2        | Part B

所以输出需要显示

Part | Location | PartDesc | Occurrence 
-----+----------+----------+--------------
A    | 2        | Part A   | 3
A    | 1        | Part A   | 2 
B    | 1        | Part B   | 1
B    | 2        | Part B   | 1

目前为止

Select Part, count(*) as occurrence
from table1
group by Part
order by count(*desc)

Answer 1

SELECT 
    Part,
    Location,
    PartDesc,
    COUNT(*) AS Occurrence
FROM
    table1
GROUP BY 
    Part,
    Location,
    PartDesc
ORDER BY 
    Occurrence DESC

谢谢。
