具有大于和小于 Sybase 数据库的计数条件

Question

我在 sybase 数据库中使用以下查询，我需要数据来显示计数（Field1 >=2 和 Field1 <=5） Select * FROM Table1 WHERE Field1 IN( SELECT Field1 FROM Table1 GROUP BY Field1 HAVING COUNT(Field1) >= 2 ORDER BY Field1我怎样才能做到这一点

Answer 1

你基本上就在那里：

Select *
FROM Table1
WHERE Field1 IN (SELECT Field1
                 FROM Table1
                 GROUP BY Field1
                 HAVING COUNT(Field1) BETWEEN 2 AND 5
                )
ORDER BY Field1;

不过，我建议 window 函数：

select t1.*
from (select t1.*, count(*) over (partition by field1) as cnt
      from table1 t1
     ) t1
where t1.cnt between 2 and 5;
