Oracle spatial query SDO_LRS with php

Hello, I have this problem,
I use php for read data from oracle table.
I know I can't show on web page the result of SDO_ORDINATE_ARRAY
Christopher Jones has written that I must use SDO_UTIL.GETVERTICES like as
from table_a, TABLE(SDO_UTIL.GETVERTICES(table_a.GEOMETRY_1)) t
id_num = 970;
But now I must read a projection point ordinate of a point with respect to a geometric segment
and the same problem come back.
esemple of spatial query that I use:
SDO_GEOMETRY(3301, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 1, 1), SDO_ORDINATE_ARRAY(580094.69, 4998493.68, NULL)) )
ID_CODE = 970;
If I use sql plus I have this result
580093,325, 4998497,57, 45,2254405))
Which is exacly the query for extract these coordinates?
Someone can help me?
My English is very bad please reply easy.
Thanks for all!

Hello thanks for all to everyboby.
I put the same question on Forum /Category/Database/Spatial and I have received this reply
from Brian Camire, this query worked well.
SDO_ORDINATE_ARRAY(580093.859, 4998493.5, NULL)
ID_CODE = 970
) T;

  • Why oracle spatial query execute so slow???

    hi all,
    I have two oracle spatial table CHI_2007r2 and CHI_2008r2, each table has it's own spatial index,and each table has 2000 row record, Now execute this query,I can get the result soon,
    select /*+ ORDERED */ a.link_id from chi_2007r2 a,chi_2008r2 b where a.link_id=b.link_id and sdo_relate(a.geom,b.geom,'mask=INSIDE querytype=WINDOW')='TRUE';
    But I execute the query by geom only,it will take so long time! query(3 more hours):
    select /*+ ORDERED */ a.link_id,b.link_id from chi_2007r2 a,chi_2008r2 b where sdo_relate(a.geom,b.geom,'mask=INSIDE querytype=WINDOW')='TRUE';
    I don't upderstand...

    Because in the first statement
    select /*+ ORDERED */ a.link_id from chi_2007r2 a,chi_2008r2 b where a.link_id=b.link_id and sdo_relate(a.geom,b.geom,'mask=INSIDE querytype=WINDOW')='TRUE'; you are joining the two tables while in the second statement
    select /*+ ORDERED */ a.link_id,b.link_id from chi_2007r2 a,chi_2008r2 b where sdo_relate(a.geom,b.geom,'mask=INSIDE querytype=WINDOW')='TRUE';you are doing a cartesian merge first because there is no join between a and b other than te sdo_relate which will be calculated for every row combination you get.
    But I think you'd be better off posting in the {forum:id=76} forum.

  • Oracle Spatial Query from SQLPLUS deteriorates in performance

    I am running an sql-procedure, which does spatial queries. When I run this procedure (from SQLPLUS) for the first time it takes around 45 sec to complete, but when I run the same procedure for the second time it takes 65 seconds and the performance keeps on decreasing. But if I open a new SQLPLUS session it takes 45 secs and it also starts deteriorating subsequently. This strange behaviour is only for spatial queries, if I don't have spatial queries in my procedure then its fine.
    I found this behaviour for any type of spatial query.
    Is there something which can be done for improving it ? I found a lot of information on improving performance of a query, but my problem is to maintain the same performance of the same query in the same session.

    Could you provide version information?
    Also, could you try monitoring memory as the procedure is running an see
    if memory climbs more each time the procedure is run?

  • Why Oracle Spatial Query So Slow???

    I have 90,000 lines in my database. When I did a query about
    finding all the lines within a certain distance of a point, it
    took me nearly 30 seconds. And when I query the intersection
    between the lines, it took me about 5 minutes!! God, I can't
    believe it!
    Do you guys met the problem before? Please share something with
    me, thank you so much!

    Are you using a spatial index for your within distance query? If
    so, what kind, and have you tuned it at all?
    As far as the intersection question goes, how many geometries are
    you testing? Are they big? Are you only comparing the ones
    returned by within distance?
    If they are big geometries, there are some very large performance
    gains in 9i when dealing with larger geometries.

  • Oracle Spatial Query

    I have created two tables the first called pai_equal created from the query below
    create table pai_equal as
    (select /*+ ORDERED */ l.*, t.toid
    from sub_lt l, sub_topoarea t
    where mdsys.sdo_relate(t.geoloc, l.geoloc,
    'mask=EQUAL querytype=WINDOW')='TRUE');
    This returns 4 rows which is correct
    This query selects the terrier polygons that are made up of one topo_area polygon only (and no more and align exactly)
    The second table is called inside_coveredby created as follows
    create table inside_coveredby as
    select /*+ ORDERED */ l.*, t.toid
    from sub_lt l, sub_topoarea t
    where mdsys.sdo_relate(t.geoloc, l.geoloc,
    'mask=INSIDE+COVEREDBY querytype=WINDOW')='TRUE'
    order by l.mi_prinx;
    Returns 1142 undistinct rows, 475(distinct)
    This query selects terrier polygons that are
    (a) made up or two or more topo area polygons and where the boundaries align exactly
    (b) made up of one or more topo area polygons and where the boundaries do not align exactly
    What I want to do next is select all the terriers that are not included in either of the above 2 queries. Totals should now add up to 754 (4 +475+ ?)as the original terrier table contains 754 features
    I think I need to select from sub_lt where mi_prinx is not in inside+coveredby or the equal table?
    Has anyone any ideas on how to write this?
    Your help as usual is much appreciated

    You can use SQL difference operator to do this:
    select toid from sub_lt
    select /*+ ORDERED */ l.*, t.toid
    from sub_lt l, sub_topoarea t
    where mdsys.sdo_relate(t.geoloc, l.geoloc,
    'mask=INSIDE+COVEREDBY querytype=WINDOW')='TRUE'
    order by l.mi_prinx;
    This should give you everything other than inside+coveredby.
    If you want to include the equal also,
    change the mask to inside+coveredby+equal.

  • Oracle Spatial Performance with 10-20.000 users

    Does anyone have any experience when Oracle Spatial is used with say 20.000 concurrent users. I am not interested in MapViewer response time, but lets say there is:
    - an app using 800 different tables each having an sdo_geometry column
    - the app is configured with different tables visible on different view scales
    - let's say an average of 40-50 tables is visible at any given time
    - some tables will have only a few records, while other can hold millions.
    - there is no client side caching
    - clients can zoom in/out pan.
    Anwers I am interested in:
    - What sort of server would be required
    - How can Oracle serve all that data (each Refresh renders the map and retrieves the data over the wire as there is no client side caching).
    - What sort of network infrastructure would be required.
    - Can clients connect to different servers and hence use load balancing or does Oracle have an automatic mechanism for that?
    Thanks in advance,

    Patrick, et al.
    There are lots of things one can do to improve performance in mapping environments because of a lot of the visualisation is based on "background" or read-only data. Here are some "tips":
    1. Spatially sort read-only data.
    This tip makes sure that data that is close to each other in space are next to each other on disk! Dan gave a good suggestion when he referenced Chapter 14, "Reorganize the Table Data to Minimize I/O" pp 580- 582, Pro Oracle Spatial. But just as easily one can create a table as select ... where sdo_filter() where the filtering object is an optimized rectangle across the whole of the dataset. (This is quite quick on 10g and above but much slower on earlier releases.)
    When implementing this make sure that the created table is created such that its blocks are next to each other in the tablespace. (Consider tablespace defragmentation beforehand.) Also, if the data is READ ONLY set the PCTFREE to 0 in order to pack the data up into as small a number of blocks as possible.
    2. Generalise data
    Rendering spatial data can be expensive where the data is geometrically detailed (many vertices) esp where the data is being visualised at smaller scales than it was captured at. So, if your "zoom thresholds" allow 1:10,000 data to be used at 1:100,000 then you are going to have problems. Consider pre-generalising the data (see sdo_util.simplify) before deployment. You can add multiple columns to your base table to hold this data. Be careful with polygon data because generalising polygons that share boundaries will create gaps etc as the data is more generalised. Often it is better to export the data to a GIS which can maintain the boundary relationships when generalising (say via topological relationships).
    Oracle's MapViewer has excellent on-the-fly generalisation but here one needs to be careful. Application tier caching (cf Bryan's comments) can help here a lot.
    3. Don't draw data that is sub-pixel.
    As one zooms out objects become smaller and smaller until they reach a point where the whole object can be drawn within a single pixel. If you have control over your map visualisation application you might want to consider setting the SDO_FILTER parameter "min_resolution" flag dynamically so that its value is the same as the number of meters / pixel (eg min_resolution=10). If this is set Oracle Spatial will only include spatial objects in the returned search set if one side of a geometry's MBR is greater than or equal to this value. Thus any geometries smaller than a pixel will not be returned. Very useful for large scale data being drawn at small scales and for which no selection (eg identify) is required. With Oracle MapViewer this behaviour can be set via the generalized_pixels parameter.
    3. SDO_TOLERANCE, Clean Data
    If you are querying data other than via MBR (eg find all land parcels that touch each other) then make sure that your sdo_tolerance values are appropriate. I have seen sites where data captured to 1cm had an sdo_tolerance value set to a millionth of a meter!
    A corollary to this is make sure that all your data passes validation at the chosen sdo_tolerance value before deploying to visualisation. Run sdo_geom.validate_geometry()/validate_layer()...
    4. Rtree Spatial Indexing
    At 10g and above lots of great work went in to the RTree indexing. So, make sure you are using RTrees and not QuadTrees. Also, many GIS applications create sub-optimal RTrees by not using the additional parameters available at 10g and above.
    4.1 If your table/column sdo_geometry data contains only points, lines or polygons then let the RTree indexer know (via layer_gtype) as it can implement certain optimizations based on this knowledge.
    4.2 With 10g you can set the RTree's spatial index data block use via sdo_pct_free. Consider setting this parameter to 0 if the table/column sdo_geometry data is read only.
    4.3 If a table/column is in high demand (eg it is the most commonly used table in all visualisations) you can consider loading (a part of) the RTree index into memory. Now, with the RTree indexing, the sdo_non_leaf_tbl=true parameter will split the RTree index into its leaf (contains actual rowid reference) and non-leaf (the tree built on the leaves) components. Most RTrees are built without this so only the MDRT*** secondary tables are built. But if sdo_non_leaf_tbl is set to true you will see the creation of an additional MDNT*** secondary table (for the non_leaf part of the rtree index). Now, if appropriate, the non_leaf table can be loaded into memory via the following:
    This is NOT a general panacea for all performance problems. One should investigate other options before embarking on this (cf Tom Kyte's books such as Expert Oracle Database Architecture, 9i and 10g Programming Techniques and Solutions.)
    4.4 Don't forget to check your spatial index data quality regularly. Because many sites use GIS package GUI tools to create tables, load data and index them, there is a real tendency to not check what they have done or regularly monitor the objects. Check the SDO_RTREE_QUALITY column in USER_SDO_INDEX_METADATA and look for indexes with an SDO_RTREE_QUALITY setting that is > 2. If > 2 consider rebuilding or recreating the index.
    5. The rendering engine.
    Whatever rendering engine one uses make sure you try and understand fully what it can and cannot do. AutoDesk's MapGuide is an excellent product but I have seen it simply cache table/column data and never dynamically access it. Also, I have been at one site which was running Deegree and MapViewer and MapViewer was so fast in comparison to Deegree that I was called in to find out why. I discovered that Deegree was using SDO_RELATE(... ANYINTERACT ...) for all MBR queries while MapViewer was using SDO_FILTER. Just this difference was causing some queries to perform at < 10% of the speed of MapViewer!!!!
    6. Consider "denormalising" data
    There is an old adage in databases that is "normalise for edit, denormalise for performance". When we load spatial data we often get it from suppliers in a fairly flat or normalised form. In consort with spatial sorting, consider denormalising the data via aggregations based on a rendering attribute and some sort of spatial unit. For example, if you have 1 million points stored as single points in SDO_GEOMETRY.SDO_POINT which you want to render by a single attribute containing 20 values, consider aggregating the data using this attribute AND some sort of spatial BUCKET or BIN. So, consider using SDO_AGGR_UNION coupled with Spatial Analysis and Mining package functions to GROUP the data BY <<column_name>> and a set of spatial extents.
    6. Tablespace use
    Finally, talk to your DBA in order to find out how the oracle database's physical and logical storage is organised. Is a SAN being used or SAME arranged disk arrays? Knowing this you can organise your spatial data and indexes using more effective and efficient methods that will ensure greater scalability.
    7. Network fetch
    If your rendering engine (app server) and database are on separate machines you need to investigate what sort of fetch sizes are being used when returning data from queries to the middle-tier. Fetch sizes for attribute only data rows and rows containing spatial data can be, and normally are, radically different. Accepting the default settings for these sizes could be killing you (as could the sort_area_size of the Oracle session the application server has created on the database). For example I have been informed that MapInfo Pro uses a fixed value of 25 records per fetch when communicating with Oracle. I have done some testing to show that this value can be too small for certain types of spatial data. SQL Developer's GeoRaptor uses 100 which is generally better (but this one can modify this). Most programmers accept defaults for network properties when programming in ADO/ODBC/OLEDB/JDBC: just be careful as to what is being set here. (This is one of the great strengths of ArcSDE: its TCP/IP network transport is well written, tuneable and very efficient.)
    8. Physical Format
    Finally, while Oracle's excellent MapViewer requires data its spatial data to be in Oracle, other commercial rendering engines do not. So, consider using alternate, physical file formats that are more optimal for your rendering engine. For example, Google Earth Enterprise "compiles" all the source data into an optimal format which the server then serves to Google Earth Enterprise clients. Similarly, a shapefile on local disk to the application server (with spatial indexing) may be faster that storing the data back in Oracle on a database server that is being shared with other business databases (eg Oracle financials). If you don't like this approach and want to use Oracle only consider using a dedicated Oracle XE on the application server for the data that is read only and used in most of your generated maps eg contour or drainage data.
    Just some things to think about.

  • About oracle spatial development platform

    Dear sir:
    At present,I can set the spatial data with oracle spatial in Oracle dba 11g,and can view map throught IE with Javascript API.But is there any oracle spatial development platform.With it ,I can drag the visual module(as:JavascriptAPI) to finish the Web page edition.Like ArcGIS,they supply them(as:throuht visual studio, API).
    Can you show me the way to get it?
    Looking forward your reply.
    Thanks your attention.

    It sounds like you are using Oracle Maps - i.e. the javascript API of Oracle MapViewer. In that case you are better off posting on the MapViewer forum:
    As for looking for a development environment, JDeveloper is likely to be your best bet for integration, but that really depends on what type of application are you developing? Is it Oracle APEX? BI? ADF? .NET? etc.

  • Poor performance with Oracle Spatial when spatial query invoked remotely

    Is anyone aware of any problems with Oracle Spatial ( with patches 6989483 and 7003151 on Red Hat Linux 4) which might explain why a spatial query (SDO_WITHIN_DISTANCE) would perform 20 times worse when it was invoked remotely from another computer (using SQLplus) vs. invoking the very same query from the database server itself (also using SQLplus)?
    Does Oracle Spatial have any known problems with servers which use SAN disk storage? That is the primary difference between a server in which I see this poor performance and another server where the performance is fine.
    Thank you in advance for any thoughts you might share.

    OK, that's clearer.
    Are you sure it is the SQL inside the procedure that is causing the problem? To check, try extracting the SQL from inside the procedure and run it in SQLPLUS with
    set autotrace on
    set timing on
    SELECT ....If the plans and performance are the same then it may be something inside the procedure itself.
    Have you profiled the procedure? Here is an example of how to do it:
    Prompt Firstly, create PL/SQL profiler table
    Prompt Secondly, use the profiler to gather stats on execution characteristics
      l_run_num PLS_INTEGER := 1;

  • How to Query Sdo_Geometry Object of ORACLE SPATIAL in PHP?

    I am trying to Query the Oracle Spatial's Geometry object in the PHP page but its giving me the ADT Error. How can i see the GEOMETRY object information on the web using PHP. Thanking you in advance and waiting for ur prompt reply.

    Hi Ana,
    In the Query below its returning the result as each value of one row in diffrent rows i wanna ask from u is:
    1- May i get all these values in one row ?
    2- Second, i want to query more than one row values from the table? as this is a single row subquery.
    Thanks for your help and i m looking forward for a positive reply from you.
    The following select lists all ordinate-values from ONE object in the table:
    select *
    from table(select a.<column_name>.sdo_ordinates
    from <table_name> a
    where ID = xxxx

  • "invalid LRS segment" when querying an Oracle Spatial DB

    I have a table of GIS segments in an Oracle Spatial database. I'm using C# and ODP to connect to the database. For a given measure from the start of a segment, I want to find the GPS coordinates for that point. I'm running the following query:
    select g.geom.sdo_ordinates ord_array from
    *(select sdo_lrs.locate_pt(shape,0.02,0) as geom from test_schema.test_table*
    where route='ABC' and segmentnum='101.1') g
    where shape is of type SDO_GEOMETRY. I'm getting the following error:
    ORA-13331: invalid LRS segment
    Is there a problem with how I'm passing shape to locate_pt()? The Oracle Spatial documentation says the argument should be SDO_geometry, so that seems ok.

    I'm using C# with ODP.NET.
    Here is the current version of the code that is failing:
    var param = new OracleParameter("geom", OracleDbType.Object);
    param.UdtTypeName = "MDSYS.SDO_GEOMETRY";
    param.Direction = ParameterDirection.Input;
    OracleCommand oCmd = new OracleCommand();
    oCmd.Connection = this.oConn;
    oCmd.CommandText = queryStr;
    oCmd.CommandType = CommandType.Text;
    OracleDataAdapter da = new OracleDataAdapter(oCmd);
    DataTable dt = new DataTable();
    The exception is generated by the da.Fill(dt) line.

  • Spatial Query with multiple geometries from 2 tables

    I'm using Oracle 8.1.7. I am trying to do a spatial query on two tables with multiple geometries. There are two spatial tables. One made up of points and one made up of polygons. There are 829551 rows in the table of points and 1817795 rows in the table with polygons...
    I want to find all polygons where one of this points is within it...
    This query is pretty intensive querying two large spatial tables against each other and so I need to find the most efficient way of running this query. I've been running variations of my query for the last two week and every time it's bombed out with various errors after 12-24 hrs processing like out of memory, out of tablespace, out of processing, invalid index etc etc etc. I need to get this query run asap... Any tips would be gratefully appreciated..
    For the session running the query I've allocated 16M sort area with
    Below is the query I'm running... How can I improve this please? BTW PARCEL_OVERLAPS contains the points and TP$_PARCEL_AREAS the polygons.
              seventy.PARCEL_OVERLAPS po,
              imap_topol.TP$_PARCEL_AREAS pa,
              TP$_PARCEL_CENTROID_AREA pca,
              TDCR_LAND_UNIT lu
              SDO_FILTER(po.geometry, pa.area,
              'querytype=WINDOW') = ’TRUE’ and
              sdo_within_distance(po.geometry,pa.area,'distance=0')='TRUE' and
              pa.delete_date is null and
              Lu.LNU_LAND_UNIT_UNIQUE_NUM = pca.CENTROID_ID and
              pa.AREA_ID = pca.AREA_ID and
              pca.DELETE_DATE IS NULL and
              pa.DELETE_DATE IS NULL;

    Thanks for your reply and the tips you've given. The tp$_parcel_areas table will always be bigger so I've changed the order to sdo_within_distance(pa.area,po.geometry,'distance=0')='TRUE'. The requested counts for those queries are
    12:26:29 [email protected]:SQL> select count(*)
    13:46:22 2 from seventy.PARCEL_OVERLAPS;
    13:48:12 [email protected]:SQL> select count(*)
    13:48:17 2 from imap_topol.TP$_PARCEL_AREAS pa,
    13:48:21 3 TP$_PARCEL_CENTROID_AREA pca
    13:48:21 4 where pca.DELETE_DATE IS NULL
    13:48:21 5 and pa.DELETE_DATE IS NULL
    13:48:21 6 and pa.AREA_ID = pca.AREA_ID;
    There was no reason for both filter and within_distance. I did try use the anyinteract but for some reason that does not return the desired results(I've added one id row as a test to make sure it returns desired results). Plus Oracle have recomended using the within distance for better performance..
