Hi
I have the table with the similar set of records which mentioned below, i'm little bit confused to find the time difference between two rows of record. By Using the MsgOut column i have to find time taken b/w PS & PV and some record doesnt have PV .
LogID LocIDClientCert MsgType MsgOutMessageTimeStamp System

Based on your sample what should the output look like?

You are going to have to explain this a bit more clearly. I would recommend starting with sample data in a consumable format. That means a create table statement and an insert statement to populate it. Then an explanation of how you get those results. From the sample data to your stated output I just don't see any correlation there at all.

Here is your data turned into something consumable.

if OBJECT_ID('tempdb..#Something') is not null

drop table #Something

create table #Something

(

LogID int

, LocID int

, ClientCert varchar(20)

, MsgType varchar(10)

, MsgOut char(2)

, MessageTimeStamp datetime

, System char(3)

)

insert #Something

select 1151334934, null, 'NOT SPECIFIED', 'Q_T12', 'PS', '2015-10-01 00:00:40.980', 'AHR' union all

select 1151335243, null, 'NOT SPECIFIED', 'D_T12', 'PV', '2015-10-01 00:00:53.800', 'AHR' union all

select 1151342944, null, 'NOT SPECIFIED', 'Q_T12', 'PS', '2015-10-01 00:05:40.957', 'AHR' union all

select 1151343281, null, 'NOT SPECIFIED', 'D_T12', 'PV', '2015-10-01 00:05:53.670', 'AHR' union all

select 1151350046, null, 'NOT SPECIFIED', 'Q_T12', 'PS', '2015-10-01 00:10:40.970', 'AHR' union all

select 1152760563, 759, 'NOT SPECIFIED', 'Q_T12', 'PS', '2015-10-01 15:28:29.617', 'AHR' union all

select 1152760739, 690, 'NOT SPECIFIED', 'Q_T12', 'PS', '2015-10-01 15:28:33.633', 'AHR'

select *

from #Something

Now if you can explain the business rules for the output I will help you create the query.

Thanks Sean,

Business of the output is to find the number of request per LocID, avg time taken per request, min time taken & max time taken.

Combination of 1 PS & 1 PV is consider as 1 request, some transaction will have only PS so such transaction we consider as one request and time consumed will be 0 Secs.

I have come up the sample resultset.

if OBJECT_ID('tempdb..#SomethingRes') is not null

drop table #SomethingRes

create table #SomethingRes

(

LogID varchar(3)

,ClientCert varchar(25)

, MsgType varchar(25)

,Response varchar(25)

,Requests int

, AveTime int

, MinimumTransactionTime int

, MaximumTransactionTime int

, Start datetime

, Finish datetime

)

insert #SomethingRes

SELECT '', 'NOT SPECIFIED', 'Unknown','PS',3,2,1,2,'2015-10-02 16:21:01.803','2015-10-22 17:14:51.900' union all

SELECT 759, 'NOT SPECIFIED','Q_T12','PS',2,2,1,2,'2015-10-07 15:49:15.277','2015-10-22 17:14:51.900' union all

SELECT 690, 'NOT SPECIFIED','Q_T12','PS',1,2,1,2,'2015-10-07 16:59:50.090','2015-10-22 17:14:51.900'

SELECT * FROM #SomethingRes

SELECT * FROM #SomethingRes

But this doesn't make any sense. There is nothing that ties a PS to a PV yet there are only 3 PS rows in the output?? Then there are number or requests but it doesn't make any sense how you come up with those values. This is probably a really simple query but there just aren't any rules that make sense yet.

Thanks a lot Sean Lange for your guidance, I planning to do some code changes in the product to log the proper logs into this table.

Thanks Once Again.
