如何根據MySQL中某些字段中值的出現次數獲取記錄？

Question

我想通過事件獲取名為ppno的字段的記錄。 即。

(GIVE ME RECORDS WHERE PPNO repeating same 5 times)

像這樣

Name   PPNO
John   TNi89873 
Smith  TNi89873 
Mark   TNi89873 
Joe    TNi89873 
Cane   TNi89873
Mary   OCSV
Mark   OCSV
Don    OCSV
Crook  OCSV
Mike   OCSV

Answer 1

像這樣

select * from tbl where ppno in
    (select ppno from tbl group by ppno having count(ppno) > 4)

Answer 2

SELECT      T1.Name,
            T1.PPNO
FROM        table AS T1
WHERE       T1.PPNO IN (SELECT     T2.PPNO
                        FROM       Table AS T2
                        WHERE      T2.PPNO = T1.PPNO
                        HAVING     COUNT(T2.PPNO) = 5)
ORDER BY    T1.PPNO,
            T1.Name

像這樣的東西（未經測試）

Answer 3

SELECT Name, PPNO FROM Table WHERE PPNO IN
(SELECT PPNO FROM Table GROUP BY PPNO HAVING Count(PPNO)=5)
