Sql 检查和并忽略零值？

我有一个交易明细表，我正试图将其编译成每笔交易的一个总和。下面是一些示例行的图像。不需要detail_id，只是在那里显示细节

我希望通过tran_num编译总计，同时忽略collections_go_to列，我需要最终结果的ID，但前提是调整ID、响应方ID、输入的日期和“位置”与tran_num的另一行匹配

我意识到这可以很容易地通过小组来完成。我的问题是，我将如何在检查之前进行基本检查，以查看是否： 传输数量和位置匹配的SUMamount 0：

所以像这样的行可以求和，然后因为是零值而被忽略

SELECT tran_num, resp_party_id, collections_go_to, SUM(amount) AS Total, 
    adjustment_id, type, impacts, clinic, date_entered
FROM dbo.transactions
WHERE (status <> 'D')
  AND (status <> 'V')
  AND (adjustment_id IS NOT NULL)
  AND (date_entered > '2015-06-01')
GROUP BY
     tran_num, resp_party_id,
     collections_go_to, adjustment_id,
     type, impacts, clinic, date_entered

这是我当前使用的数据视图，我暂时忽略paytype_id列

编辑更新：感谢您的回复，HAVING子句似乎是处理其中一些问题的方法，但不幸的是，在计算检查时需要忽略collections\u go\u to列，否则我只会得到tran\u num的多个结果。是否有一种方法可以在不使用collections\u go\u to列的情况下执行子查询检查，从而消除任何这样的tran\u num结果为零，但我仍然需要集合go to ID。也许可以查看哪个tran num total为零，然后从最终结果中提取这些ID，作为HAVING子句的替代方法，将查询包装为如下子查询：

SELECT tran_num, resp_party_id, collections_go_to, Total, 
        adjustment_id, type, impacts, clinic, date_entered
FROM (
    SELECT tran_num, resp_party_id, collections_go_to, SUM(amount) AS Total, 
        adjustment_id, type, impacts, clinic, date_entered
    FROM dbo.transactions
    WHERE (status <> 'D')
      AND (status <> 'V')
      AND (adjustment_id IS NOT NULL)
      AND (date_entered > '2015-06-01')
    GROUP BY
         tran_num, resp_party_id,
         collections_go_to, adjustment_id,
         type, impacts, clinic, date_entered
)T
WHERE T.Total <> 0

虽然这里的用法看起来很简单，但总体来说这是一种非常强大的技术。还可以使用CTE实现相同的效果，同时提高可读性：

;WITH T as (
    SELECT tran_num, resp_party_id, collections_go_to, SUM(amount) AS Total, 
        adjustment_id, type, impacts, clinic, date_entered
    FROM dbo.transactions
    WHERE (status <> 'D')
      AND (status <> 'V')
      AND (adjustment_id IS NOT NULL)
      AND (date_entered > '2015-06-01')
    GROUP BY
         tran_num, resp_party_id,
         collections_go_to, adjustment_id,
         type, impacts, clinic, date_entered
)
SELECT tran_num, resp_party_id, collections_go_to, Total, 
        adjustment_id, type, impacts, clinic, date_entered
FROM T
WHERE T.Total <> 0

via：有

  SELECT tran_num, resp_party_id, collections_go_to, SUM(amount) AS Total, 
         adjustment_id, type, impacts, clinic, date_entered
  FROM dbo.transactions
  WHERE (status <> 'D')
    AND (status <> 'V')
    AND (adjustment_id IS NOT NULL)
    AND (date_entered > '2015-06-01')
  GROUP BY
    tran_num, resp_party_id,
    collections_go_to, adjustment_id,
    type, impacts, clinic, date_entered
  Having sum(amount) <> 0
