寫一個多重查詢條件使用相同的列相同的表

Question

在我的表中一個提交的是味精。基於這兩個條件提出。條件是

where msg like '%fatal%' or msg like '%exception%' or msg like '%fopen%' 

then Select telco , 
Sum(Case when a= '1' then 1 else 0 end) as a, 
Sum(Case when b= '2' then 1 else 0 end) as b, 
Sum(Case when c= '3' then 1 else 0 end) as c, 


where msg not like '%fatal%' or msg not like '%exception%' or msg not like '%fopen%' 
then Select telco , 
Sum(Case when a= '1' then 1 else 0 end) as a_e, 
Sum(Case when b= '2' then 1 else 0 end) as b_e, 
Sum(Case when c= '3' then 1 else 0 end) as c_e, 

From temp_inbox group by t 

這裏，B，C列名

我想寫上述要求一個查詢。如果我寫了兩個查詢基兩大WHERE條件，然後我得到的結果，但我想編寫一個查詢，並顯示在下面的方式我的結果：

a b c a_e b_e c_e 

5 6 7 10 4  10 
1 2 7  45 20 2 

樣本數據：

  a b c msg 

     1 0 0 fatalerror 

     0 0 3 successed 
     1 0 0 exception 
     0 2 0 successful

select telco, 
sum(
    case when (msg like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '1' 
    then 1 else 0 end 
) as a, 
sum(
    case when (msg like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '2' 
    then 1 else 0 end 
) as b, 
sum(
    case when (msg like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '3' 
    then 1 else 0 end 
) as c, 
sum(
    case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '1' 
    then 1 else 0 end 
) as a_e, 
sum(
    case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '2' 
    then 1 else 0 end 
) as b_e, 
sum(
    case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '3' 
    then 1 else 0 end 
) as c_e 

From temp_inbox group by t 

或您可以在嵌入時使用嵌套的情況

可以使用UNION語句來加入兩列具有相同列數的查詢：

我不知道你有什麼做的，但你所提到會是這個樣子的表UNION語句：

select sum(a), message from telco where message like '%fatal%' 
UNION 
select sum(a), message from telco where message not like '%fatal%'
