how to choose which row to insert with same id in sql?

I have a table called “table_1” :

ID   Index          STATUS          TIME        DESCRIPTION
1     15          pending           1:00       Started Pending
1     16          pending           1:05       still in request
1     17          pending           1:10       still in request
1     18          complete          1:20       Transaction has been completed
2     19          pending           2:25       request has been started
2     20          pending           2:30       in progress
2     21          pending           2:35       in progess still
2     22          pending           2:40       still pending
2     23          complete          2:45       Transaction Compeleted

I need to insert these data into my second table “table_2” where only start and complete times are included, so my “table_2” should be like this:

ID   Index   STATUS          TIME          DESCRIPTION
1     15     pending         1:00          Started Pending
1     18     complete        1:20          Transaction has been completed
2     19     pending         2:25          request has been started
2     23     complete        2:45          Transaction Completed

Here is some code I already have, I have problem getting the right associated description because it does not appear in the GROUP BY clause.

INSERT INTO myTable2 (ID, STATUS, TIME)
SELECT ID, STATUS, MIN(TIME) FROM myTable1 t1top
WHERE EXISTS(SELECT * FROM myTable1 WHERE ID=t1top.ID AND STATUS='Complete')
GROUP BY ID, STATUS
ORDER BY ID  ASC, STATUS DESC

If anyone can help me write sql query for this I would highly appreciate it.

Answer 1

INSERT INTO myTable2 (ID, STATUS, TIME, DESCRIPTION)
SELECT t1.ID, t1.STATUS, t1.TIME, t1.DESCRIPTION FROM table_1 as t1 
WHERE STATUS = 'complete' 
OR TIME = (SELECT min(TIME) FROM table_1 WHERE ID = t1.ID) 
ORDER BY ID asc, STATUS desc
