sql - Determine how long a phase takes, looking at current row and next row -

-

I am working on a project for work, using the data logging type system currently SQL Server 2008, if Upgrade if necessary. We are currently taking 1 minute interval of equipment, we are collecting all types of information, I am only concerned about time, and step number.

I am trying to determine the length of time, the machine spends in a certain step before going out. I have a way that I use it currently. Although it takes a long time to run (5+ hours)

I currently have a visual set that looks like this. 

 with  with steps (select *, ROW_NUMBER ()) at the time (depending on the time) from the RONM FOR dbo.Data_All. Time, step Y On Steps as Inner Join Steps from the [Production Stage] Step Rowlum = y. Rome + 1 and phase. [Production phase] & lt; & Gt; Y [production phase]

By doing this, I start to break, at the time that he entered that stage, it will take about 30 seconds to run, so it should not be bad . Realize that we have more than 250,000 records, which are seeing every day, and growing.

| Time | Step #. ----------------------------- | 7-25-2014 14:32 | 11 | | 7-25-2014 15:32 | 13. | 7-25-2014 15:40 | 14 | | 7-25-2014 15:42 | 15 | | 7-25-2014 15:50 | 8 |

Then I'm running a query that to see, to get me, phase, time, next step time, and period This is a question which is taking longer, so I am looking for a way to do it fast. Choose CTI (time), select row number = = ROW_NUMBER (), (order by time), [Time_In_Step from the production phase] [current row]. [Production phase], [current line] [time time] Time, [next line]. Time] [next line] on the [next row] as the [minimum period] from the CTE [current line] to join the CAT [minimum period]. Row_Numbers = [current line] .ow_numbers + 1

After doing this, I get the following, which is what I want. This is just a quick way to do this 

  | Time | Step #. Next Step Time Duration in the minimum. -------------------------------------------------- --------------- | 7-25-2014 14:32 | 11 | 7-25-2014 15:32 | 60 | | 7-25-2014 15:32 | 13. 7-25-2014 15:40 | 8 | | 7-25-2014 15:40 | 14 | 7-25-2014 15:42 | 2 | | 7-25-2014 15:42 | 15 | 7-25-2014 15:50 | 8 | | 7-25-2014 15:50 | 8 | Etc .. | DateDiff

Any ideas about how to optimize this? Please tell me what you are trying to do, you need more ideas about it.

I cross apply : 

  Select c. [Production phase], c.Time, NTEM AS [N Step Time], Dedifff (Mile, Sea Time, N. Time) AS [Minimum Period] Time To Apply Intestate C Cross (Select Top 1 N. * Time_In_Step N From where c.time & lt; n.time) n; An index display will help in

time .

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
