Spatial index creation for table with more than one geometry columns?

I have table with more than one geometry columns.
I'v added in user_sdo_geom_metadata table record for every column in the table.
When I try to create spatial indexes over geometry columns in the table - i get error message:
ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-13203: failed to read USER_SDO_GEOM_METADATA table
ORA-13203: failed to read USER_SDO_GEOM_METADATA table
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 8
ORA-06512: at line 1
What is the the solution?

I'v got errors in my user_sdo_geom_metadata.
The problem does not exists!

  • Error while running spatial queries on a table with more than one geometry.

    Hello,
    I'm using GeoServer with Oracle Spatial database, and this is a second time I run into some problems because we use tables with more than one geometry.
    When GeoServer renders objects with more than one geometry on the map, it creates a query where it asks for objects which one of the two geometries interacts with the query window. This type of query always fails with "End of TNS data channel" error.
    We are running Oracle Standard 11.1.0.7.0.
    Here is a small script to demonstrate the error. Could anyone confirm that they also have this type of error? Or suggest a fix?
    What this script does:
    1. Create table object1 with two geometry columns, geom1, geom2.
    2. Create metadata (projected coordinate system).
    3. Insert a row.
    4. Create spacial indices on both columns.
    5. Run a SDO_RELATE query on one column. Everything is fine.
    6. Run a SDO_RELATE query on both columns. ERROR: "End of TNS data channel"

    This error appears in GeoServer and SQLPLUS.
    I have set up a completly new database installation to test this error and everything works fine. I tried it again on the previous database but I still get the same error. I also tried to restart the database, but with no luck, the error is still there. I geuss something is wrong with the database installation.
    Anyone knows what could cause an error like this "End of TNS data channel"?

  • ADF Table with more than one TableSelectMany column

    Does anyone know how to add more than one TableSelectMany component to a table? So, basically I'm trying to have two checkboxes for each row in the table
    thanks,
    Eric

    Eric,
    the TableSelectMany column is element of the selection facade which only takes one element.
    To create additional checkboxes, you can - of course - add an additional table column to the table and add a checkbox to it

  • Error with SDO_TUNE.EXTENT_OF on a table with more than one geometry.

    Hello,
    I'm using a GeoServer with Oracle Spatial database, and I run into some problems. GeoServer uses SDO_TUNE.EXTENT_OF to calculate the maximum extent of features you add. It works fine for all object with only one geometry, but fails for objects that has two geometry columns. The error is ORA-01422.
    Is this a bug in Oracle, or am I doing something wrong? I know SDO_AGGR_MBR works fine, but I'd rather not use it, since if it is possible I would like to avoid changing the GeoServer functions.
    Here is a small script I created to show this error:
    1. Create two tables, object1 with one geometry and object2 with two geometry columns.
    2. Create metadata (projected coordinate system).
    3. Insert two rows, one in each table.
    4. Create spacial indices.
    5. Calculate extent, on object1 it will succeed, on object2 it will fail.
    6. Clean.

  • How to create Dynamic Table with more than one column?

    Hi,
    I'm trying to learn Dreamweaver. I'm trying to display 2 units from my database in the same row then I would like go to next row.
    By default DW shows single record in each row. Is it possible to display more than one?
    Thank you

    Of course. You will not name the divs differently, they will all be <div class="RowContainer">  (in the example below) and the reason they will look like
    1 2
    3 4
    5 6
    is because they will "stack themselves up". That is, the first will float to the top left, the next will float up next to it. The third will not fit on the top line floating next to two, so it will start a new row. Four will float up next to it, and five will start the new row.
    Think of the string of divs (don't put wordspaces between them...) as a continuous ribbon or chain of divs. That is a slightly poor analogy, since the second and third won't be next to each other, as a chain or a ribbon might be. But you should be able to have as many divs as you have records... you define the div in the CSS and in your page markup really only show one div.
    Here's a modified example from one of my files:
    <div spry:region="ds1" class="...">
      <div spry:repeat="ds1" class="RowContainer"> <!--this is the div that you would style to float -->
        {category} {title} {medium}<br>
         {price} {sold} {date}<br>
         {sold_to_purchase_price}
      </div>
    </div>

  • Checkbox with more than one display column.

    Hi.
    I have a checkbox item which I reference in a process (stored procedure) in my page. I'd like to display more than one field for the item, in different columns.
    The lov query allows only 2 fields, the display value and the return value.
    For now I just concatenate the 2 display fields, but I would like to display them in 2 different columns.
    Is this possible?
    My other option would be to use a report and set the item type to a simple checkbox. Is it possible then to reference the values of the report checkbox in my process ?
    Thanks in advance.

    Any ideas anyone?

  • EEWB: Insert New Table with more than one key field  for BP object

    Hi Gurus,
    I want to enhance Business Partner object with a new table with two key fields, one the address number and another a sequence number, because I need to save several entries for each address belonging to a determined business partner. Something as what happens in communication data (i.e fax number)for an address.
    I have run the wizard from EEWB but the only possibility that offers you is to create only one key field for the new custom table. There is something in EEWB to achieve this, two key fields for the new table?
    Another question is the following: which Badi or BAPI must I enhance to populate my table with the corresponding address number to which the data belong to?
    I mean my custom data are filled through a table control that I have allocated within the screen sequence BUA130 (Detail Address). Thus, when a new address is added to a BP and my particular table control is populated within this address I should fill the key fields from my table (address number and sequence number) when the BP were saved. So, I must know beforehand which address number the system will assign to this new address.
    I repeat the question: which Badi or BAPI must I enhance to populate my table with the corresponding address number to which the data belong to?
    Thanks in Advance.

  • Rendering a table with more than one record per "row"

    Ok, it's like this. I have a collection that I want to render as an ADF Table with a single column. Except I want to render multiple entries in the collection per row of the table
    i.e. a normal ADF table would be like:
    [Column Header]
    [Row1.TextField]
    [Row2.TextField]
    [Row3.TextField]
    [Row4.TextField]
    [Row5.TextField]
    I would like to render it something like:
    [Column Header]
    [Row1.TextField] [Row2.TextField] [Row3.TextField]
    [Row4.TextField] [Row5.TextField]
    That is, I want to add each record's text field horizontally first before adding a new row vertically.
    Any way to do this with the ADF Table? Or is there another component I should use?

    Hi,
    you can try the "af:iterator" component
    example
    <af:panelGroupLayout id="pgl4" layout="horizontal">
                    <af:iterator id="i1" value="#{bindings.MyTree.collectionModel}"
                                 var="row" varStatus="vs">

                        <af:outputText value="#{row.CityCode}" id="ot2"/>
                      </af:panelGroupLayout>

  • More than one SDO_GEOMETRY columns in one Oracle 8i spatial table

    I have a spatial table as follows:

  • Table with more than 35 columns

    Hello All.
    How can one work with a table with more than 35 columns
    on JDev 9.0.3.3?
    My other question is related to this.
    Setting Entities's Beans properties from a Session Bean
    bought up the error, but when setting from inside the EJB,
    the bug stays clear.
    Is this right?
    Thank you

    Thank you all for reply.
    Here's my problem:
    I have an AS400/DB2 Database, a huge and an old one.
    There is many COBOL Programs used to communicate with this DB.
    My project is to transfer the database with the same structure and the same contents to a Linux/ORACLE System.
    I will not remake the COBOL Programs. I will use the existing one on the Linux System.
    So the tables of the new DB should be the same as the old one.
    That’s why I can not make a relational DB. I have to make an exact migration.
    Unfortunately I have some tables with more than 5000 COLUMNS.
    Now my question is:
    can I modify the parameters of the ORACE DB to make it accept Tables and Views with more than 1000 columns, If not, is it possible to make a PL/SQL Function that simulate a table, this function will insert/update/select data from many other small tables (<1000 columns). I want to say a method that make the ORACLE DB acting like if it has a table with a huge number of columns;
    I know it's crazy but any idea please.

    When you try to create a PK you automaticaly created an index. If you want to put this index in different tablespace you should use 'using index..' option when you create this primary key.

  • Row chaining in table with more than 255 columns

    Hi,
    I have a table with 1000 columns.
    I saw the following citation: "Any table with more then 255 columns will have chained
    rows (we break really wide tables up)."
    If I insert a row populated with only the first 3 columns (the others are null), is a row chaining occurred?
    I tried to insert a row described above and no row chaining occurred.
    As I understand, a row chaining occurs in a table with 1000 columns only when the populated data increases
    the block size OR when more than 255 columns are populated. Am I right?
    Thanks

    dyahavYesterday, I stated this on the forum "Tables with more than 255 columns will always have chained rows." My statement needs clarification. It was based on the following:
    http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/schema.htm#i4383
    "Oracle Database can only store 255 columns in a row piece. Thus, if you insert a row into a table that has 1000 columns, then the database creates 4 row pieces, typically chained over multiple blocks."
    And this paraphrase from "Practical Oracle 8i":
    V$SYSSTAT will show increasing values for CONTINUED ROW FETCH as table rows are read for tables containing more than 255 columns.
    Related information may also be found here:
    http://download.oracle.com/docs/cd/B10501_01/server.920/a96524/c11schem.htm
    "When a table has more than 255 columns, rows that have data after the 255th column are likely to be chained within the same block. This is called intra-block chaining. A chained row's pieces are chained together using the rowids of the pieces. With intra-block chaining, users receive all the data in the same block. If the row fits in the block, users do not see an effect in I/O performance, because no extra I/O operation is required to retrieve the rest of the row."
    http://download.oracle.com/docs/html/B14340_01/data.htm
    "For a table with several columns, the key question to consider is the (average) row length, not the number of columns. Having more than 255 columns in a table built with a smaller block size typically results in intrablock chaining.
    Oracle stores multiple row pieces in the same block, but the overhead to maintain the column information is minimal as long as all row pieces fit in a single data block. If the rows don't fit in a single data block, you may consider using a larger database block size (or use multiple block sizes in the same database). "
    Why not a test case?
    Create a test table named T4 with 1000 columns.
    With the table created, insert 1,000 rows into the table, populating the first 257 columns each with a random 3 byte string which should result in an average row length of about 771 bytes.

    Paraphrase misspelled the view name "V$SYSSTAT", corrected a couple minor typos, and changed "will" to "may" in the closing paragraph as this appears to be the behavior based on the test case.
