多个SQL查询where子句

Question

我有多个SQL查询与不同的where子句：

select * from (
    SELECT ov.state_nm, ov.state_id,us.client_id, us.rebate_qtr_id, 
    sum(cvr.rebate_per_claim) as flagged 
    FROM [dOVT_OutlierView].[APP01DBA].[OVT_USER_STATE_ASSIGNMENT] us 
    inner join ovt_states ov on us.state_id=ov.state_id 
    inner join OVT_LABELER_CLIENT_STATE_SETTINGS css 
    on css.client_id=us.client_id and us.state_id=css.state_id 
    inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT] cvr 
    on us.client_id= cvr.client_id 
    and css.client_id=cvr.client_id 
    inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT_USER_DECISION] udes 
    on udes.client_id=cvr.client_id 
    and udes.client_id=css.client_id and us.client_id=udes.client_id 
    where us.assigned_to_user_id=81 and us.company_id=50 and us.client_id=23 

    group by ov.state_id, us.client_id,ov.state_nm,us.rebate_qtr_id) a 
    cross join (

    SELECT 
    sum(cvr.rebate_per_claim) as follwup 
    FROM [dOVT_OutlierView].[APP01DBA].[OVT_USER_STATE_ASSIGNMENT] us 
    inner join ovt_states ov on us.state_id=ov.state_id 
    inner join OVT_LABELER_CLIENT_STATE_SETTINGS css 
    on css.client_id=us.client_id and us.state_id=css.state_id 
    inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT] cvr 
    on us.client_id= cvr.client_id 
    and css.client_id=cvr.client_id 
    inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT_USER_DECISION] udes 
    on udes.client_id=cvr.client_id 
    and udes.client_id=css.client_id and us.client_id=udes.client_id 
    where us.assigned_to_user_id=81 and us.company_id=50 and us.client_id=23 
    and udes.followup_dispute_ignore_flg='F' 
    group by ov.state_id, us.client_id,ov.state_nm,us.rebate_qtr_id) b 

上述两种选择中括号查询是一样的，只是where子句在第二查询加入。仅用于合并目的，我已将交叉连接添加到两个查询中。

是否有其他方法可以在不重复查询的情况下执行此操作？

Answer 1

我只想把这个第一个查询的选择部分，去掉交叉连接的一部分，你应该得到你所需要的。

sum(case when udes.followup_dispute_ignore_flg='F' then cvr.rebate_per_claim else 0 end)as follwup 

所以

select 
    ov.state_nm, ov.state_id, 
    us.client_id, 
    us.rebate_qtr_id, 
    sum(cvr.rebate_per_claim) as flagged, 
    -- just a new line here 
    sum(case when udes.followup_dispute_ignore_flg='F' then cvr.rebate_per_claim else 0 end)as follwup 
from [dOVT_OutlierView].[APP01DBA].[OVT_USER_STATE_ASSIGNMENT] us 
inner join ovt_states ov on us.state_id=ov.state_id 
inner join OVT_LABELER_CLIENT_STATE_SETTINGS css 
    on css.client_id=us.client_id and us.state_id=css.state_id 
inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT] cvr 
    on us.client_id= cvr.client_id and css.client_id=cvr.client_id 
inner join [APP01DBA].[OVT_CLAIM_VALIDATION_ALL_RESULT_USER_DECISION] udes 
    on udes.client_id=cvr.client_id and udes.client_id=css.client_id and us.client_id=udes.client_id 
where us.assigned_to_user_id=81 and us.company_id=50 and us.client_id=23 
group by ov.state_id, us.client_id,ov.state_nm,us.rebate_qtr_id 

Answer 2

你可以做这样的事情。首先建立你的主查询，并加入所有的连接。然后建立你的摘要查询。然后在最后交叉加入两个汇总查询。

     ,ov.state_id
