Question

3我有以下查询

SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  table
  WHERE run_date >= Dateadd(month, -4, Getdate())
  and test_alias='BOND_P' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 1.79 AND 4.5

和

     SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  ems.cdotests
  WHERE run_date >= Dateadd(month, -3, Getdate())
  and test_alias='CAA/CCC' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 2.79 AND 2

我需要结合此查询，以便我可以将输出作为

1: result set of query 1 intersected with result set of query 2
2: result set of query 1 unioned with result set of query 2

'Intersect'或'Union'将取决于传递给存储过程的参数

Ps注意：两个查询之间的运行日期条件可以不同任何帮助将不胜感激

Answer 1

IF @myBitParameter = 0
  SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  [table]
  WHERE run_date >= Dateadd(month, -4, Getdate())
  and test_alias='BOND_P' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 1.79 AND 4.5 

  UNION ALL --or UNION, if you don't want duplicates

  SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  ems.cdotests
  WHERE run_date >= Dateadd(month, -3, Getdate())
  and test_alias='CAA/CCC' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 2.79 AND 2

ELSE
  SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  [table]
  WHERE run_date >= Dateadd(month, -4, Getdate())
  and test_alias='BOND_P' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 1.79 AND 4.5 

  INTERSECT

  SELECT deal_id, max(test_value) - min(test_value) AS deviation
  FROM  ems.cdotests
  WHERE run_date >= Dateadd(month, -3, Getdate())
  and test_alias='CAA/CCC' 
  group by deal_id
  having (max(test_value) - min(test_value)) BETWEEN 2.79 AND 2

我觉得应该有一种方法可以用CTE来清洁它，但是没有时间再愚弄它了。有人可以随意清理它或者从中得到更好的答案。

添加多个条件到group by和having子句
