Oracle: merging two different queries into one, LIKE & IN

(1 个回答)

我有以下代码:

case when (a.je_source='Revaluation') then 'No_Location' 
when d.user_name like ('SCHE%') then 'No_Location'
when d.user_name like ('C-FA%') then 'No_Location'
when d.user_name like ('C-AGO%') then 'No_Location'
when d.user_name like ('C-VD%') then 'No_Location'
when d.user_name like ('C-JL%') then 'No_Location'
else d.user_name
end as JE_User

有没有办法让它更干净?我尝试了以下操作,但收到了缺少右括号的错误。
case when (a.je_source='Revaluation') then 'No_Location'
when d.user_name like ('SCHE%', 'C-FA%') then 'No_Location'
else d.user_name
end as JE_User

最佳答案

作为一个选项,您可以使用(oracle 10g 及以上)regexp_like健康)状况:

     -- sample of data
SQL> with t1(je_source, user_name) as(
2 select 'Revaluation1', 'SCHE123' from dual union all
3 select 'Revaluation2', 'C-FABCD' from dual union all
4 select 'Revaluation3', 'C-AGOABC' from dual union all
5 select 'Revaluation4', 'C-VD' from dual union all
6 select 'Revaluation5', 'C-JLABC' from dual union all
7 select 'Revaluation', 'ABCDE' from dual union all
8 select 'Revaluation6', 'FGHIJ' from dual
9 )
10 select je_source
11 , user_name
12 , case
13 when je_source = 'Revaluation'
14 then 'No_Location'
15 when regexp_like(user_name, '^SCHE\w*|^C-FA\w*|^C-AGO\w*|^C-VD\w*|^C-JL\w*', 'i')
16 then 'No_Location'
17 else user_name
18 end case
19 from t1
20 /

JE_SOURCE USER_NAME CASE
------------ --------- -----------
Revaluation1 SCHE123 No_Location
Revaluation2 C-FABCD No_Location
Revaluation3 C-AGOABC No_Location
Revaluation4 C-VD No_Location
Revaluation5 C-JLABC No_Location
Revaluation ABCDE No_Location
Revaluation6 FGHIJ FGHIJ
