tsql - Conditional where statement in T-SQL -

-

i've got table returns history of value, current one, each date.

the oldest date main record. if value changed, new record created, old value, , main record updated new value. if happens again, third record created, contains old value.

so if value starts @ 4, changes 2, again changes 1. records go 

1 4 2

i'm creating inner join on table follows, gets max date of 3 above records, 2.. actual value need 4. easiest way tell if record historical 1 triageenddatetime null.

inner join (select emergencyattendanceid,min(sourcecreatedatetime) max_date                 factemergencyattendancetriagedetail                  group emergencyattendanceid) eaid                  on eaid.emergencyattendanceid = factemergencyattendancetriagedetail.emergencyattendanceid                 , eaid.max_date = factemergencyattendancetriagedetail.sourcecreatedatetime

what need select second record, if exists. along lines of this. 

 select emergencyattendanceid,min(sourcecreatedatetime) max_date     factemergencyattendancetriagedetail      if count(emergencyattendanceid) > 1 triageenddatetime null else not null     group emergencyattendanceid      inside inner join.

can me this?

sample data

alt text

in above case, record 2 1 i'm after.

try this:

    select emergencyattendanceid       case when count(emergencyattendanceid) > 1           min           (           case when triagedatetime null sourcecreatedatetime end            )      else           min(sourcecreatedatetime)     end max_date       factemergencyattendancetriagedetail      group emergencyattendanceid
