问题
I have below mentioned data. I am looking to get min of Start message and corresponding min of success message. If there is no start or success message present then it should show null.

5678 null 5/19/2014 14:00:16 5/19/2014 pqr null success null 400
I am trying to get Min of start_timestamp in combination with the very next Min of success_timestamp corresponding to id1 and jobid. If there is a list of start message and no success message for a given id1 and jobid, then it should show NULL and viceversa. Tried using Temporary table using WITH clause and also used self join method. Below is my query, But WITH clause query returns MIN of overall data in the table.
Query Used:
WITH DATA AS
(SELECT MIN(smt.column13) timestamp_for_success_message
FROM success_table1 smt, start_table2 b
WHERE
(SMT.id1 = b.id1)
AND (SMT.jobid = b.jobid)
AND (SMT.timestamp_for_success_message_recieved >= b.timestamp_for_start_message_recieved)
)
SELECT distinct a.timestamp_for_success_message_recieved,
b.timestamp_for_start_message_recieved,
b.id1,
b.jobid
FROM data a,
start_table2 b
order by b.timestamp_start_message_recieved, a.timestamp_for_success_message_recieved, b.jobid, b.id1;

Closest I can get is this: You'll notice my below query is showing some starts without ends .. you don't explain what to do with those. Also, my query links different starts and ends from you. You said
"Min of start message and start_secs to pair up with min of success message"
Which I did below, and it links: "264 with 4280", not "165 with 4280" as you showed. Since 262 was paired up with 290, that means 264 is now the MIN to be matched with the MIN of success, 4280. If you can further clarify your requirements, I can tweak the query.

Trying to understand what you're after, it seems you want to completely ignore the SECONDS component of the listed times? And treat the resulting times as duplicates if they then match (ie 9:21 = 9:31 .. since 9:00 = 9:00 ).
If that's the case, then this query returns your sample (aside from your typo on "11:45:15" showing as "11:45:25" ;)
