SQL Server - Select using CASE inside FROM -


i'm trying select using case clause inside from didn't figure how can it.

actually, how select like:

select     a.userid,       isnull(sent, 0) sent,      isnull(received,0) received            (select         tt1.userid userid,         sum(totalusers) sent                     #tabletemp1 tt1     inner join         #tabletemp2 tt2 on tt1.userid = tt2.userid             tt1.status = -1     group         tt1.userid)         left join           .....

i need change statement inside () this:

select     a.userid,       isnull(sent, 0) sent,      isnull(received, 0) received            (case tt1.exportdate         when null                        select                 tt1.userid userid, totalsent sent              sentdata              inner join dataconsolidated dc on cde.userid = dc.userid           else             select                  tt1.userid userid, sum(totalusers) sent                     #tabletemp1 tt1             inner join #tabletemp2 tt2 on tt1.userid = tt2.userid             tt1.status = -1     group tt1.userid        end)          left join          ......

i know don't have 'tt1' when call case i'm kinda lost in sql clauses.

any appreciated.

if in stored procedure, recommend putting logic in if/else block. however, if doing inline query, might better-off running both sets (with conditions result in empty set) , union results. this:

select a.userid,         isnull(sent,0) sent,        isnull(received,0) received             (                    select tt1.userid userid, totalsent sent             sentdata inner join dataconsolidated dc on cde.userid = dc.userid             tt1.exportdate null             union             select tt1.userid userid, sum(totalusers) sent                    #tabletemp1 tt1                 inner join #tabletemp2 tt2 on tt1.userid = tt2.userid            tt1.status = -1              , tt1.exportdate not null            group tt1.userid   )           left join          ......
