I am using two tables here projections_report p
and access_rights a
. I can't find out why I am getting the error:
subquery returns more than one row
(case when paramChannel='AllC' then p.gl_sal_chan in
(case when dc_lob=0 then (select distinct pr.gl_sal_chan from
projections_report pr) else (select distinct pr1.gl_sal_chan
from projections_report pr1 where pr1.gl_sal_chan
in (select distinct a.gl_sal_chan from access_rights
a where a.userid= paramUserId)) end)
else p.gl_sal_chan = paramChannel end)
I tried using all and any keywords. Please help.
Thanks in advance.
I tried to do it in another way and got it right. Firstly I changed the statement in else condition of second case statement to
(select distinct gl_sal_chan from access_rights where userid = paramUserid)
as both return the same result(my bad) and secondly I changed the entire condition to
(case when (paramChannel = 'AllC' && dc_lob = 0) then '%' = '%' else
(case when (paramChannel='AllC' && dc_lob != 0) then
gl_sal_chan in (select distinct gl_sal_chan from access_rights where userid = paramUserid)
else gl_sal_chan= paramChannel end)end)
Anyway Thanks @all :)
在使用子查询时,在子查询中使用LIMIT仅返回一条记录,它可能返回多个记录
