我想通过事件获取名为ppno的字段的记录。即。

(GIVE ME RECORDS WHERE PPNO repeating same 5 times)


像这样

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

最佳答案

像这样

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