• Creation of spatial data connectivity data

  Hello
  
  I have a few spatial data, which I'll try to describe the relevant aspects:
  
  -A LineSegment table, which contains information about cables, including the ID of the area (approximately 4 million lines)
  -An array of location, that contains a LineSegmentID (one by one), and a column (space) geometry (approximately 4 million lines).
  
  What I need to do, is to create a new table containing conceptual "nodes", containing the following columns:
  
  -NodeID (number)
  -(Number) LineSegmentID
  -LineSegmentEnd (1 or 2)
  
  So I need to prepare, for each cable, which other cable it connects, by comparing its ends with the endpoints of other cables in the same sector. A box contains cables up to 464. There are a total of 160 thousand areas.
  
  I'm working on the most effective way to achieve this, ideally by making a batch which will take less than half an hour. Oracle is relatively new to me, but I'm guessing that the right approach would be to use a series of intermediate (intermediate) tables, as I believe nested cursors would be much too slow (I ran a simple test to confirm this).
  
  I guess I'll have to get in a temporary table, the starting point and the end point of each cable using SDO_LRS. GEOM_SEGMENT_START_PT and SDO_LRS. GEOM_SEGMENT_END_PT, as well as the area ID. Join the table to itself, and then use SDO_GEOM. SDO_DISTANCE to work on what points are close together (for example less than one meter). However, I'm fighting to describe a step by step process.
  
  Anyone has any ideas that can help?

  Examples of data to illustrate the problem:
  
  create table line_location (lineid number,
  geometry sdo_geometry);
  create table (ID, areaid) line;
  
  -a cable in the box 1, 2 in area 4, etc.

  Hi Ronnie

  Have you had a look at the script on the old NET?
  This done in a slightly different result structure, what you're after.
  I took the time this morning to see a bit optimized.

  Below you will find the result.

  With clues about a couple and the use of the SDO_JOIN rather the sdo_relate this speeds up considerably.
  I had tested on a 600 k line objects (which is not 4 million I know) and is reasonable ok on my test (non optimized) environment.

  On the "1 metre" close to each other, I would have supported itself by setting the tolerance appropriately, so
  There should be no reason to perform within the distance checking. Obviously that permitting the resolution of your data.

  Have a look at.

  Note that the final table is different in their structure, but this needs to be easily adjusted in the script if your node_line table must be exactly like you defined.

  You can try SDO_GEOM. VALIDATE_GEOMETRY_WITH_CONTEXT
  or SDO_GEOM. VALIDATE_LAYER_WITH_CONTEXT? for example

  Select * from base_sdo where
  SDO_GEOM. VALIDATE_GEOMETRY_WITH_CONTEXT (a.CA, 0,000005). = "TRUE";

• Spatial data acquisition Oracle through WFS

  Hello
  
  I did research for a while and am a bit confused.
  
  I have Oracle Spatial 11 g with geometry data and would like to be able to retrieve these data through a WFS for a viewing application.
  
  Here's where I'm confused:
  (1) space offers a WFS service must be configured. If I set this up, I would be able to access the data through getFeature URL commands? The documentation I see for them has applications for getFeature in the form of XML files, so I don't know if I can do it. Also, it seems that the service returns the .log files, but I think not I want GML...
  
  If this is the option that I must take the tutorial to configure OC4J and Web Services are for a Linux (http://www.oracle.com/technology/obe/11gr1_db/datamgmt/spatialws/spatialws.htm)--are there one for 64-bit Windows?
  
  (2) do I need an another "application layer" to enable support for this URL? I know that MapServer can use URL requests... can I run against the data in my PB and forget the WFS Oracle?
  
  (3) MapViewer seems to work with themes WFS and process applications through Java and SQL... It's another option?
  
  I'm basically confused as to where everything is and what I should focus on to get my spatial data of the DB through a WFS. Any help on this would be greatly appreciated!
  
  Thank you!

  Yes, with a server Oracle Spatial and logic of the Web, you can get support for WFS.
  Note that you must space Oracle 11 GR 2 to work with the logical Web server.

  MapVeiwer can only consume the WFS themes, so it does not help with what you want to do here.

• MapViewer not able to query spatial data?

  Hello, I would like to ask questions about how to query non-space data with MapViewer.
  
  When I read the manual, I found a method using JavascriptAPI. The doQuerymethod.
  Can someone help me, give examples on how to use this method? Because I'm so confuse how to use it.
  
  Is there another method of application not database using MapViewer?
  I use JSP to build my application and I prefer a method in the Javascript API.
  
  
  
  Thank you very much.
  I really appreciate your help.

  With the doQuery method, you can retrieve values of attribute in a table. The first row of the returned String table attribute names, and the following lines have the attribute values. The following code is an example of querying the table of STATES to get the name of the State and the population value.

       /* SELECT state, tot_pop FROM states
         The following illustrates the first rows in the returned String[][]:
  
              STATE    TOTPOP
              Alabama   4040586
              Alaska     550043
              Arizona   3665228
  
         The first row has the attribute names.
      */
  
      String [][]query = mapViewer.doQuery("mvdemo",
               "select state, totpop from states");
  
       int nlin = 0;
       int ncol = 0;
       String name = null;
       double totPop = 0.;
       if(query != null)
       {
         nlin = query.length;
         ncol = query[0].length;
  
         for(int i=1;i[0];try{totPop = Double.parseDouble(query[i][1]);} catch (Exception ex){totPop = 0.;}
  
  System.out.println("[State] " + name + " [Population] " + totPop);}}

• Date ranges query

  Hi Experts,

  A very happy new year to all of you (a little in advance)!

  I have a table where I have the id of employee and the task assigned with the start dates and end dates. Overlap in the dates of the tasks is a data delivers however I know how to spot them and eliminate. There is therefore no date of tasks that overlap

  Employee_id

  Task_No

  Task_Start_date

  Task_End_Date

  Examples of data

  1 T1 1 January 2014 February 28, 2014

  1 T2 March 1, 2014 31 December 2014

  2 T1 23 January 2014 31 December 2014

  2 T2 1 January 2015 December 31, 2073 (means end of time)

  3 T3 1 January 2014 July 15, 2014

  3 T4 August 1, 2014 31 December 2014

  T5 4 1 January 2014 December 31, 2073

  I want to design a query where I provide the end date and it will list all the employees that are free for the same day from 1 January 2014. Thus, for example, if I give December 31, 2014, it will list the

  EmpId (first day where the employee is free)

  2 January 1, 2014

  3 July 16, 2014

  If I give the end = end date of time(31-Dec-2013), result-

  EmpId (first day where the employee is free)

  1 January 1, 2015

  2 January 1, 2014

  3 July 16, 2014

  If I give the end = date January 31, 2014, expected - result

  EmpId (first day where the employee is free)

  1 January 1, 2015

  I conceived after the request, but he intercepted not 2 employee ID. Also, it provides no flexibility to change end date-

  Select *.

  from (select employe_id,

  task_start_date,

  task_end_date,

  lag (task_end_date, 1, task_start_date) on prev_end_date (partition by employee_id arrested by task_start_date)

  of shop.employee_tasks

  where task_end_date > = trunc (sysdate))

  where task_start_date - prev_end_date > 1

  Thanks in advance!

  Kind regards

  This is an example of what I call the query 'free time': you have the dates when you are busy and you want the dates where you are free.

  You can find a nice solution for the problem of base here: ask Tom "SQL Query to find gaps in the date ranges" (search for solution of Anthony Boucher). Please note that this solution works even with the date ranges overlap.

  To apply the solution here, first create the test data (please do it yourself in the following questions).

  create table t(Employee_id, task_no, Task_Start_date, task_end_date)
  as select
  1, 'T1', to_date('01-jan-2014'), to_date('28-feb-2014') from dual union all select
  1, 'T2', to_date('01-Mar-2014'), to_date('31-Dec-2014') from dual union all select
  2, 'T1', to_date('23-jan-2014'), to_date('31-dec-2014') from dual union all select
  2, 'T2', to_date('01-jan-2015'), to_date('31-dec-2073') from dual union all select
  3, 'T3', to_date('01-jan-2014'), to_date('15-jul-2014') from dual union all select
  3, 'T4', to_date('01-aug-2014'), to_date('31-dec-2014') from dual union all select
  4, 'T5', to_date('01-Jan-2014'), to_date('31-Dec-2073') from dual;
  

  In the query, you must add records for yesterday and for the "end date" you want. This allows you to "free time" before and after the date ranges in your table.

  Now, you partition by order of Task_Start_date and employe_id. Using the analytical function of the max (task_end_date), you get the last date of end so far. Add 1 and you get the first time (maybe). To make sure that the date is free, it must be before the next start date.

  variable end_date varchar2(64)
  exec :end_date := '31-Dec-2073';
  --
  with boundaries as (
    select trunc(sysdate)-1 task_start_date, trunc(sysdate)-1 task_end_date from dual
    union all
    select to_date(:end_date)+1, to_date(:end_date)+1 from dual
  ), data as (
    select * from t
  where task_end_date >= trunc(sysdate)
    and task_start_date < :end_date
    union all
    select distinct a.employee_id, null, b.task_start_date, b.task_end_date
    from t a, boundaries b
  )
  select employee_id, min(free_start) free_start
  from (
    select employee_id,
    max(task_end_date) over (partition by employee_id order by task_start_date)+1 free_start,
    lead(task_start_date) over (partition by employee_id order by task_start_date)-1 free_end
    from data
  )
  where free_start <= free_end

  Joe,

  Try to use the GeoRaptor for SQL Developer extension. Download SQL Developer of RTO and then get GeoRaptor from Sourceforge.

  What is a SDO_DIM_ELEMENT?

  You logically implies that your example shows how do it manually using SQL.

  No hard and fast rule. Usually most of the people would determine the rectangular extent (or MBR) their data and enter the RADIUS X and Y, as determined by the coordinates lower left and upper right.

  For geodetic data (IE long/lat) more simply placed in the scope of the world full of-180, 180 and - 90.90. But others within the scope of their data. Read the documentation on that.

  How to know the value of SDO_DIM_ELEMENT ('X', 0, 20, 0.005) of the card? y at - it a tool that could enable?

  See above. Try any package of GIS, or GeoRaptor or

  select SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,1) as minx,
         SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,3) as maxx,
         SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,2) as miny,
         SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,4) as maxx
    from (select sdo_aggr_mbr(geom) as mbr
            from PLANNING_NEIGHBORHOODS);
  -- Result
  --
        MINX       MAXX       MINY       MAXX
  ---------- ---------- ---------- ----------
  5979385.646    6024741 2085840.482    2131294 
  

  Or...

  select 'SDO_DIM_ARRAY(' ||
         'SDO_DIM_ELEMENT(''X'','||
            SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,1) || ',' ||
            SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,3) || ',0.05' ||
      '),SDO_DIM_ELEMENT(''Y'',' ||
         SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,2) || ',' ||
         SDO_GEOM.SDO_MIN_MBR_ORDINATE(mbr,4) || ',0.05))' as dimarray
    from (select sdo_aggr_mbr(geom) as mbr
            from PLANNING_NEIGHBORHOODS);
  -- Result
  --
  DIMARRAY
  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X',5979385.6456569,6024740.99982789,0.05),SDO_DIM_ELEMENT('Y',2085840.48152296,2131294.0001958,0.05))
  

  The sdo_tolerance in the SDO_DIM_ELEMENT's your guess as to degree of accuracy of the data are. Reflect on how close two points are allowed to be before they are considered equal. 0.05 is 5cm (standard for long/lat data) and means two summits cannot be narrower than that otherwise you will get an error the summits in double (13356) during the validation of your data using sdo_geom.validate_geometry ().

  what different SDO_DIM_ELEMENT

  The metadata that describe the extent of your data. Written correct spatiali to user_sdo_geom_metadata is it necessary for indexing.

  SDO_ELEM_INFO_ARRAY and SDO_ORDINATE_ARRAY?

  objects that are used to describe a space object.

  How to set the SDO_ELEM_INFO_ARRAY and SDO_ORDINATE_ARRAY of the card?

  I don't think that it is the starting point to reinvent the wheel by trying to explain what is well explained in the Oracle documentation.

  Therefore, I suggest that you read Chapter 1 spatial Concepts (http://docs.oracle.com/cd/E11882_01/appdev.112/e11830/sdo_intro.htm#i884907) and then come back and ask us questions.

• Search weekend Dates through query

  I'm setting up a report in the APEX to show all the JEs which have been posted on the weekends. I can query all GL records and adjust the date, but I have no odea how to identify the dates that fall on Saturday or Sunday and. We run EBS 11i. I can send the basic query if that helps.
  
  
  Any help would be appreciated.

  Assuming that 'weekend' always means Saturday and Sunday and that your sessions always use English NLS settings,

  SELECT *
    FROM your_gl_table
   WHERE TO_CHAR( journal_entry_date, 'fmDAY' ) IN ('SATURDAY', 'SUNDAY' );
  

  or

  SELECT *
    FROM your_gl_table
   WHERE TO_CHAR( journal_entry_date, 'D' ) IN ('1' '7' );

  The financial year begins on 1 August and ends July 31? Who wouldn't be August to July , not August to August ?

  Sorry, we don't know what you want.

  Here's a way to get the period_name of the accounting year:

  SELECT  TO_CHAR ( ADD_MONTHS (SYSDATE, 5)
            , '"AUG-"yyyy'
            )     AS this_period_name
  FROM    dual;
  

  The 'magic number' is 5 as your fiscal year begins 5 months before the calendar year.

  You have a table that contains a period_name, and you will have to filter it with this value? If so

  ...
  WHERE   period_name  BETWEEN  'AUG-2003'
                 AND      TO_CHAR ( ADD_MONTHS (SYSDATE, 5)
                                       , '"AUG-"yyyy'
                            )     
  

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• OIM 11 g - adjustment process form data through query API

  Hello
  
  I would define the shape of process via the API data request. I have a user configured in AD. Now I would like to define form data to process (title) through the API request. I have imported the necessary data and that it works through UI request. But when I try to do this through query API, the value is not updated in the form of process. Can anyone help with a code example to achieve this functionality? Thank you.

  You define the data of application correctly when creating on-demand via the API? There is also the correct attribute in all reference maps data? What about the attribute itself? It is in the form of parent or child?
  Looking at the title of the ad must be the parent form data, so use the following code as an example to update all data correctly:

  
             long resKey = 0L;
             String str = null;
             String resourceKey = null;
             Map searchMap = new HashMap();
             tcResultSet resultSet = null;
             RequestData requestData = null;
             Beneficiary beneficiary = null;
             RequestBeneficiaryEntity entity = null;
             List beneficiaryList = null;
             List entityList = null;
             List entityAttrList = null; 
  
             searchMap.put(RESOURCE_ATTR_NAME, RESOURCE);
             resultSet = _resourceService.findObjects(searchMap);
             resKey = resultSet.getLongValue(RESOURCE_ATTR_KEY);
             resourceKey = Long.toString(resKey);           
  
             RequestBeneficiaryEntityAttribute parantAttr = new RequestBeneficiaryEntityAttribute();
             parantAttr.setType(TYPE.String);
             parantAttr.setName("Title");
             parantAttr.setValue("Mr.");
  
             entityAttrList = new ArrayList();
             entityAttrList.add(parantAttr);
  
             entity = new RequestBeneficiaryEntity();
             entity.setEntityKey(resourceKey);
             entity.setEntityType(RequestConstants.RESOURCE);
             entity.setEntitySubType(RESOURCE);
             entity.setEntityData(entityAttrList);
  
                entityList = new ArrayList();
             entityList.add(entity);
  
             beneficiary = new Beneficiary();
             beneficiary.setBeneficiaryType(Beneficiary.USER_BENEFICIARY);
             beneficiary.setBeneficiaryKey(USER_KEY);
             beneficiary.setTargetEntities(entityList);          
  
             requestData = new RequestData();
             requestData.setRequestTemplateName(TEMPLATE);
             requestData.setJustification("Test");
             requestData.setBeneficiaries(beneficiaryList);
  
             RequestService reqsrvc = client.getService(RequestService.class);           
  
             str = reqsrvc.submitRequest(requestData);
  
             System.out.println("Value from submitRequest : '" + (str != null ? str : null) + "'");
  

  Just a dummy code, but it's the overall structure. Once you have submitted the request and commissioning successful, you should see the data in the form of process.

  Hi guys,.
  
  Do means that, if we have 2 GB of cache buffers allocated to Oracle, we can only store up to 2 GB of data in memory?
  
  Thank you

  Yes, this means that you can at any time, can have 2 GB of blocks cached in your memory.

• BI Publisher data model / query question

  Hello
  
  I'm designing a report of BI Publisher where I need to show negative numbers in red. I'm perfectly fine with the help of the conditional formatting to do this (just using the default value is conditional formatting in the add-in in MS Word, that generates code like this:)
  
  <? If: number(Cost_-_MTD) < 0? > <? attribute@InContext:color;' Red '? > <? end if? >
  
  BUT...
  
  I have columns returning who sometimes have a NULL value in them, and when they have the value NULL, it causes the foregoing to the pipe upwards. So I thought, 'I'll just add IfNull() in queries defined in the model data, and who will take care of the problem... "
  
  that works - a little. Now, my problem is if I have to go back and change the query for some reason, I get an error "query cannot be parsed, please modify the query manually. I really don't want to do that, I wish that other developers do NOT have to manually change the queries.
  
  So my question is - is it possible to add in the IfNull() directly in the query designer, so it should not be changed manually from that moment?
  
  p.s. using IfNull OBIEE server as our data source.
  
  Thanks in advance,
  Scott

  I don't think there is a way to add the ifnull condition in the query designer. So, you will need to manually change the query...

  In your model so you can add additional control like this:
  <0?>...

  Thank you!
