如何比較兩個表並只顯示結果不等於0

Question

我想要做一個sql查詢，它將採用兩個視圖並比較數據中的差異並僅顯示非零的數據。到目前爲止，我有以下，但它出現一個錯誤，說「子查詢返回多個值。」使用您正在使用哪個`RDBMS` SQL Server 2008中

select * from stl_wk_vw where 
ABS((select sum(missing+non_missing) as total from tdn_summary as b join stl_wk_vw as a on a.id = b.id group by b.id) 
- 
(select sum(st_total) from stl_wk_vw as a join tdn_summary as b on a.id = b.id where standard not like '%non' group by b.id)) > 0 

Answer 1

SELECT * 
FROM stl_wk_vw a 
JOIN tdn_summary b 
ON  b.id = a.id 
GROUP BY 
     b.id 
HAVING ABS(SUM(missing + non_missing)) > SUM(CASE WHEN standard NOT LIKE '%non' THEN st_total END)
