如何在这里使用havng count的SQL查询？

Question

我有以下数据的表（Tbl_Test）。

  RecordId  BatchName   Numbers  MQC   
      1   20150443   321106   0  
      2   20150430   321107   0 
      3   20150430   321107   1 
      4   20150412   321110   2 
      5   20150430   321118 
      6   20150430   321120 
      7   20150432   321120 
      8   20150430   321126 
      9   20150432   321127 
      10   20150430   321129 
      11   20150431   321129 

从上面的表格我想输出一样，数列，其计数大于1

 RecordId  BatchName   Numbers  MQC   
     2   20150430   321107   0  
     3   20150430   321107   1 
     6   20150430   321120 
     7   20150432   321120 
     10   20150430   321129 
     11   20150431   321129 

我已经试过以下选择，但没有成功：

select RecordId,BatchName,Numbers,MQC 
from Tbl_Test 
group by RecordId,BatchName,Numbers,MQC 
having count(Numbers)>1 

Answer 1

一个解决方案是使用Common table expression。
试试这个：

;With CTE AS 
(
    SELECT Numbers, 
      Count(1) As NumberOfRows 
    FROM Tbl_Test 
    GROUP BY Numbers 
) 

SELECT T.* 
FROM Tbl_Test T 
INNER JOIN CTE ON(T.Numbers = CTE.Numbers) 
WHERE NumberOfRows > 1

Answer 2

在MQC上使用GroupID上的RecordID进行计数。

'Count（RecordId）Group By MQC'应该为你工作。

Answer 3

;WITH CTE AS 
(
    SELECT 
    RecordId, 
    BatchName, 
    Numbers, 
    MQC, 
    count(*) over (partition by Numbers) cnt 
    FROM tbl_test 
) 
SELECT 
    RecordId, BatchName, Numbers, MQC 
FROM CTE 
WHERE cnt > 1 

Answer 4

您可以使用GROUP BY与HAVING和IN .Something这样。

SELECT * FROM Tbl_Test 
WHERE Numbers IN 
(
    SELECT Numbers 
    FROM Tbl_Test 
    GROUP BY Numbers 
    HAVING COUNT(*) > 1 
)
