Pivot Rows to Column in SQL without Aggregation

You can use conditional aggregation:

select object_key,
       max(case when name = 'OBJECT_NAME' then value end) as object_name,
       max(case when name = 'Start Time' then value end) as start_time,
       max(case when name = 'End Time' then value end) as end_time,
       max(case when name = 'row_count' then value end) as row_count,
       max(case when name = 'Execution Time' then value end) as execution_time
from t
group by object_key;

I'm not sure why you specify "no aggregation" in the question.

If you really have an aversion to aggregation use can use joins:

select ton.object_key, ton.value as object_name,
       ts.value as start_time, te3.value as end_time,
       . . 
from t ton on
     t ts
     on ton.object_key = ts.object_key join
     t te
     on ton.object_key = t3.ojbect_key. join
     . . . ;
