Mapping XSD to a relational table

Hi
I jdeveloper how do i go about mapping a XSD file to a relational table ?
I know some tools like xml spy ca do these can jdeveloper do this ?
regards

When using the DATAEXPORT command to export data for direct insertion into a relational database:
● The table to which the data is to be written must exist prior to data export
● Table and column names cannot contain spaces
Check with the below syntax.
SET DATAEXPORTOPTIONS
DATAEXPORTDECIMAL 1;
DataExportLevel "LEVEL0";
DATAEXPORTCOLHEADER "Periods";
FIX("FY2011","Budget","Version1",FixedAssets,"Amount","622185","3011","BU_None" ,@LEVMBRS(Periods,0) AND @DESCENDANTS(Annual,0),@LEVMBRS(Currencies,0));
DATAEXPORT "DSN" "bfp" "ClaritydataCS.dbo.BEAM_Output_Budget" "bfpcssql" "pBaUsDsGwEoTrd123";
ENDFIX;

  • Mapping with xml-schema XML-data to relational tables

    Hello,
    is it possible to map data from xml documents to relational tables with xml-schema?
    I mean not in nested tables but in relational tables with primary and foreign keys!
    With SQL Server 2005 it is very easy, I dont believe that Oracle couldn't do this!
    I searched but i cant find anything about that!
    Thx
    user445232

    indeed, oracle does this for xml schema based xmltype data, however, these underlying tables are not accessable to the application. Maybe It should for next version, so folks who like to use relational model can use it without mapping it manually.
    Actually, nested tables, are the same, their underlying tables (segments) are indeed relational tables, oracle manages them internally and not visiable to the application. You can find them in the user_segments, user_objects views though.

  • XML file validation with XSD and loading to database relational table

    Hi all,
    I have some xml files coming to my unix directory. I will be having an XSD for those. My task is to validate those xml against given xsd and load the corresponding data into oracle relational tables with sqlloader only.
    Please help me to accomplish. and let me know the contents of control file ( for SQLLOADER) if i want to load the xml directly to database.
    Unix and/or PLSQL suggestions both are welcome.

    My problem area is loading the XML to Oracle relational tables using sqlloader.
    suppose, the xml is <?xml version="1.0"?>
    <Customers>
    <Customer>
    <CustID>1</CustID>
    <Company>Bell South</Company>
    <City>New York</City>
    </Customer>
    <Customer>

    how to insert the xml data into the table???
    please help..

  • Mapping to Relational tables

    We are new to Oracle OLAP and AWM.
    These are the questions we have :
    1. Is there a way to map to external files rather than RDBMS for populating the cubes ? If so, how in AWM ?
    2. If i want to have the cubes populated every day for 1 year time, should the RDBMS also (that maps the cube) should have one year data ?.
    Once the cube is populated for yesterday from RDMS, can i not remove the yesterday's data from RDMS and load only the new data in RDBMS.
    In such a case, the cube should have yesterdays data and the newly added data from today.
    The intent is that, the RDBMS should have just 1 day or 1 week data but the cube should have 1 year data...

    1. Is there a way to map to external files rather than RDBMS for populating the cubes ? If so, how in AWM ?Define an RDBMS external table that maps to the external files and then map the cube to this table. See http://docs.oracle.com/cd/E11882_01/server.112/e22490/et_concepts.htm for more details.
    2. If i want to have the cubes populated every day for 1 year time, should the RDBMS also (that maps the cube) should have one year data ?.
    Once the cube is populated for yesterday from RDMS, can i not remove the yesterday's data from RDMS and load only the new data in RDBMS.
    In such a case, the cube should have yesterdays data and the newly added data from today.
    The intent is that, the RDBMS should have just 1 day or 1 week data but the cube should have 1 year data...The default behaviour of cubes defined in AWM is to add new data during each cube build and keep existing data (unless it is overridden in a cell). So if you build once a day from a fact table that contain only one day of data, then eventually the cube will contain a year of data. This is controlled by the "default cube script" for the cube. You need a cube script without a CLEAR command.
    Given this setup, you should think about using the LOAD SERIAL option in the DBMS_CUBE.BUILD script. For example
    exec DBMS_CUBE.BUILD('MY_CUBE USING (LOAD SERIAL, SOLVE)')This will cause the server to access the external table only once instead of once per partition. The per partition load makes sense if there are indexes on the fact table, but this is not going to be true in your case. It also make sense (in all cases) if you plan to partition the cube by DAY.

  • How to create XML from relational tables based on an XML Schema ?

    There is no automated way in Oracle XML DB to define an automatic mapping between a set of columns in some existing relational tables and the elements and attributres defined by an XML Schema.
    However it is easy solve this problem by using the SQL/XML operators (XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES, etc) to generate XML documents that are compliant with an XML Schema directly from a SQL statement.
    If the XML Schema is registered with Oracle XML DB and the appropraite Schema Location information is added into the generated document using XMLAttributes then it becomes very easy to ensure that the generated documents are valid.
    The following example show an easy way to do this by creating an XML View that contains the documents to be validated.

    There is no automated way in Oracle XML DB to define an automatic mapping between a set of columns in some existing relational tables and the elements and attributres defined by an XML Schema.
    However it is easy solve this problem by using the SQL/XML operators (XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES, etc) to generate XML documents that are compliant with an XML Schema directly from a SQL statement.
    If the XML Schema is registered with Oracle XML DB and the appropraite Schema Location information is added into the generated document using XMLAttributes then it becomes very easy to ensure that the generated documents are valid.
    The following example show an easy way to do this by creating an XML View that contains the documents to be validated.

  • XML DB to Relational table?

    Hi Everybody,
    We have a situation to map the elements/attributes of XML tables in XML DB (Oracle 9i) to target relational tables.
    We have XML schema as starting point. Do you have any white paper or documentation to help us do mapping ?
    I appreciate your help.
    Ram

    You can start from here:
    http://otn.oracle.com/tech/xml/xmldb/index.html

  • From XML in CLOB to relational table doubt

    versions 11.2.0.2.0 / 10.2.0.4.0
    It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.
    It's *<IntrBkSttlmAmt Ccy="???">999999</IntrBkSttlmAmt>*
    For the rest the below works in both versions but used on an xml having a 10000 <CdtTrfTxInf> on 11g it took 9 seconds and was killed because no answer was produced after 30 minutes on 10g. A colleague using java loaded the relational table in 34 seconds on 10g and produced the relational table on 11g in just 5 seconds.
    The 10g version is surviving with no xmldb installed and there are rumors our thinking heads didn't succeed to deactivate it on 11g yet.
    Any suggestion concerning alternate ways to produce a relational table from an xmltype located in a clob column of a relational table are welcome
    (looking at CLOB in XML to Normal table Best approach? I thought too many xmltable would have to be used)

    Hi,
    It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.When you use this :
    <Ccy>{$r/IntrBkSttlmAmt/@Ccy}</Ccy>That doesn't set the value of the Ccy element with the attribute value, but actually add the attribute Ccy to the element Ccy, which results in
    <Ccy Ccy="???"></Ccy>Knowing that, you have three options :
    1) Leaving the XQuery as it is and using this instead in the COLUMNS clause :
                             ccy             varchar2(50)    path '/rw/Ccy/@Ccy',2) Modifying the XQuery to get the atomic value out of the attribute (using the fn:data function) :
                              <Ccy>{fn:data($r/IntrBkSttlmAmt/@Ccy)}</Ccy>3) Simplifying the whole thing, something like :
    select v.instrid, v.endtoendid, v.txid, v.cd, v.ccy,
           replace(v.intrbksttlmamt,'.',',') as intrbksttlmamt, v.chrgbr, v.bic1, v.nm1, v.adrline11, v.adrline12, v.ctry1, v.iban1,

  • Generate xml output file from relational table

    Hi All,
    I'd like to generate an XML file from a relational table but would like to persist the XSD in Oracle does anyone have a working example?
    Edited by: houchen on Jun 2, 2009 5:34 AM

    From the FAQ on the {forum:id=34} forum, {thread:id=416001}.
    If you are wanting to register the schemas in Oracle, you will find info on that as well in the FAQ.

  • Approach to parse large number of XML files into the relational table.

    We are exploring the option of XML DB for processing a large number of files coming same day.
    The objective is to parse the XML file and store in multiple relational tables. Once in relational table we do not care about the XML file.
    The file can not be stored on the file server and need to be stored in a table before parsing due to security issues. A third party system will send the file and will store it in the XML DB.
    File size can be between 1MB to 50MB and high performance is very much expected other wise the solution will be tossed.
    Although we do not have XSD, the XML file is well structured. We are on 11g Release 2.
    Based on the reading this is what my approach.
    1. CREATE TABLE XML_DATA
    (xml_col XMLTYPE)
    XMLTYPE xml_col STORE AS SECUREFILE BINARY XML;
    2. Third party will store the data in XML_DATA table.
    3. Create XMLINDEX on the unique XML element
    4. Create views on XMLTYPE
    CREATE OR REPLACE FORCE VIEW V_XML_DATA(
       Stype,
       Mtype,
       MNAME,
       OIDT
    AS
       SELECT x."Stype",
              x."Mtype",
              x."Mname",
              x."OIDT"
       FROM   data_table t,
              XMLTABLE (
                 '/SectionMain'
                 PASSING t.data
                 COLUMNS Stype VARCHAR2 (30) PATH 'Stype',
                         Mtype VARCHAR2 (3) PATH 'Mtype',
                         MNAME VARCHAR2 (30) PATH 'MNAME',
                         OIDT VARCHAR2 (30) PATH 'OID') x;
    5. Bulk load the parse data in the staging table based on the index column.
    Please comment on the above approach any suggestion that can improve the performance.

    I was not aware of Virtual column but looks like we can use it and avoid creating views by just inserting directly into
    the staging table using virtual column.
    Suppose OID id is the unique identifier of each XML FILE and I created virtual column
    CREATE TABLE po_Virtual OF XMLTYPE
    XMLTYPE STORE AS BINARY XML
    VIRTUAL COLUMNS
    (OID_1 AS (XMLCAST(XMLQUERY('/SectionMain/OID'
    PASSING OBJECT_VALUE RETURNING CONTENT)
    AS VARCHAR2(30))));
    1. My question is how then I will write this query by NOT USING COLMUN XML_COL
    SELECT x."SECTIONTYPE",
    x."MACHINETYPE",
    x."MACHINENAME",
    x."OIDT"
    FROM po_Virtual t,
    XMLTABLE (
    '/SectionMain'
    PASSING t.xml_col                          <--WHAT WILL PASSING HERE SINCE NO XML_COL
    COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
    MachineType VARCHAR2 (3) PATH 'MachineType',
    MachineName VARCHAR2 (30) PATH 'MachineName',
    OIDT VARCHAR2 (30) PATH 'OID') x;
    2. Insetead of creating the view then Can I do
    insert into STAGING_table_yyy ( col1 ,col2,col3,col4,
    SELECT x."SECTIONTYPE",
    x."MACHINETYPE",
    x."MACHINENAME",
    x."OIDT"
    FROM xml_data t,
    XMLTABLE (
    '/SectionMain'
    PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
    COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
    MachineType VARCHAR2 (3) PATH 'MachineType',
    MachineName VARCHAR2 (30) PATH 'MachineName',
    OIDT VARCHAR2 (30) PATH 'OID') x
    where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
    insert into STAGING_table_yyy ( col1 ,col2,col3
    SELECT x."SectionOID",
    x."EventName",
    x."OIDT"
    FROM xml_data t,
    XMLTABLE (
    '/SectionMain'
    PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
    COLUMNS SectionOID PATH 'SectionOID',
    EventName VARCHAR2 (30) PATH 'EventName',
    OID VARCHAR2 (30) PATH 'OID',
    ) x
    where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
    Same insert for other tables usind the OID_1 virtual coulmn
    3. Finaly Once done how can I delete the XML document from XML.
    If I am using virtual column then I beleive it will be easy
    DELETE table po_Virtual where oid_1 = '99dd48cf-fd1b-46cf-9983';
    But in case we can not use the Virtual column how we can delete the data
    Thanks in advance

  • Converting Relational Tables to Object Views

    We have extra information stored for each
    field in a table. We call these Vertical
    Tables:
    rowid primary key - ties to normal tab
    column_name "" - ties to column in ""
    text_value the value if text
    reliability rating for level of accuracy...
    date of entry
    Yes there are normal tables that the applications also access if they just need the value of the columns.
    So I want to take this to object views. This way, while oracle is learning how to alter objects, we can still maintain our data and old application while converting to the use of objects.
    I thought the best solution would be Type(s) based on the orignal data type. A generic type, text65_t could be created to hold every column that is less than 65 characters long:
    CREATE TYPE text65_t AS OBJECT
    WITH OBJECT IDENTIFIER(row_id) AS
    row_id VARCHAR2(30),
    value VARCHAR2(65),
    reliability NUMBER(1,0),
    doe DATE
    A view can easily be created of this. The
    mapping is one to one.
    My problem is the next level. How can I build another view on top of text65_t, integer_t, date_t... that ties all of the
    vertical rows back into a normal relational table or object.
    Thanks,

  • 10g: Must all related tables be in the same project?

    Since we will eventaully have over 500 tables to map, we would like to be able to maintain these tables/classes in different projects. How do we map foreign key references between tables/classes that we would like to maintain in different projects?
    I don't know if theis is why I'm getting this error, but I initially created two projects with independent tables. Then I wanted to join some tables in one project to some tables in another project. (This is all using Offline Database Objects.) I dropped some tables managed in project A into the diagram for project B and created the foreign key relations (from B to A.) Now whenever I try to open the TopLink Mappings node for project B in the Navigator, I get the following error. I get this error even if I drop ALL the tables from project A into project B's diagram (meaning there is nothing left in the schema that could be the missing 'parent'.)

    If you wish to split your project up into two projects and have some relationships between some of those objects in the projects, you could map all of the objects for each project, but do not map the relationships. For those classes with relationships to other classes in other project you can define an amendment method. An amendment method is a callback into Java code that will be called when the descriptor is loaded. In this method you can then create the mapping to the class in the other project through the descriptor and mapping code API. (see oracle.toplink.mappings, oracle.toplink.publicinterface.Descriptor)
    You can also make use of descriptor deactivation to define relationships between projects. For this you would import the related classes into the project and deactivate them. This will allow you to define relationships to them, but will not export their mapping information when deploying.
    In general it is probably easier to keep everything in one project and use your content/code management system and merge tools to manage the project.

  • Syntax of DDL options and related (table) column names

    Hi,
    where can I find something like a mapping between DDL options and related table column names?
    For example I do have the table options PCTFREE, FREELISTS and NOCOMPRESS. The related table columns out of user_tables are PCT_FREE, FREELIST and COMPRESS.
    PCT(_)FREE wins an Underscore, FREELIST(S) wins an "S" and it is "NOCOMPRESS" if COMPRESS has a value "Y(es)".
    Hope somebody can help.

    So far I didn't find any information that is not in
    the DDL script gernerated from
    DBMS_METADATA.get_DDL.Alright, I give you an example:
    I create a table with the following DDL:
    "CREATE TABLE IntBuch (
    int_bunr integer NOT NULL,
    int_sdat double precision NOT NULL,
    int_hblz char(8) NOT NULL,
    int_hkto char(7) NOT NULL,
    int_hdat double precision NOT NULL,
    KtoNr char(7) NOT NULL,
    BLZ char(8) NOT NULL,
    CONSTRAINT PK_IntBuch PRIMARY KEY (int_bunr)
    USING INDEX

    ON DELETE CASCADE
    ADD FOREIGN KEY (KtoNr,BLZ) REFERENCES Konto
    ADD FOREIGN KEY (int_bunr) REFERENCES Buchung
    ON DELETE CASCADE
    After that I read the DDL with DBMS_METADATA.get_DDL and I get

    If there are no more DDLOptions possible than that, it is fine for me. If not, but all kinds of options are to find in only one or two tables of the database ( user_tables for table options, dba_constraints and dba_segments for column options, primary and foreign keys, user_indexes and user_segments for indexes ...), that is fine for me, too. (As long as I get to know which tables are "sufficient" for that.) If it is different than both of that, that's bad.
    However if you want to use defaults instead of
    absolut values, it is better to remove certain parts,
    like the storage clause, from the generated output.I understand this, but I am more interested to have all and not leaving out some of them in order to have the defaults in the database after running the DDL.
    A totally different approach could be to
    a) create a database link from one DB to another.
    b) create table <new_table> as select * from
    <[email protected]> where 1=2;I keep that in mind, thanks for that hint.

  • Create XML (using DTD) from multiple relation tables

    Hello and thank you in advanced.
    I'm trying to create an XML document, based on a specific DTD, by selecting information from multiple tables in the database.
    Is there a tool (in XDK maybe?) that will allow me to map my relational tables to a specific DTD?
    I could build the XML manually, but I was hoping that Oracle has already solved this problem with an automated tool.
    Thanks again,
    Sean Cloutier

    Is that the same thing as me writing an XSQL document which contains all of my queries (or views).
    In other words, do I have to map everything by hand or is there a tool to do that for me?
    thanks again,

  • Sequencing for relation table

    i have a many-to-many relation with a
    relation table.
    the relation table has a "id" - column as primary key
    and two foreign keys columns
    REL_TABLE
    ID | TABLE_A_ID | TABLE_B_ID
    where at the toplink workbench can i define
    the sequencing for the "id" - column ?
    thanks

    A relation table that contains any additional information, such as its own PK or qualifying fields, is not a typically mapped using a M:M. TopLink's M:M mapping assumes the relation table contains only the two FKs, which together form the PK of the table.
    The simplest solution is to map another class to the relation table that has its own unique identity for each relationship and then configure sequencing on this mapped class.

  • How to insert into xml table from relational table

    I wrote a sqlstaement that selects value from the relational tables. Now I want to replace root node "<event_start01>" with following value to the above selected xml string. My select returns root node and all nodes and elements of the root node.
    I tried holding above sellected value into varchar2 variable but I get ora-00600 error. If I hold above selected values into xmltype variable then I am not able to replace root node with the following value.
    I want to rplace rootnode with the following string.
    INSERT INTO FRMD_EVENT_START01(xml_event_start) VALUES
    (XMLTYPE('<event_start01
    xmlns="event_start01.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="event_start01.xsd
    event_start01.xsd">

    Normally, you'd do this by joining B, C, and D together. In the simplest case, something like
    INSERT INTO A( col1, ... col10 )
      SELECT B.col1, ..., B.col4,
             C.col5,
             D.col6, ..., D.col10
        FROM B,
             C,
             D,
       WHERE B.someKeyColumn = C.someKeyColumn
         AND C.anotherKeyColumn = D.anotherKeyColumnYou'd have to know how the data in B, C, and D relate to fill in the WHERE clause. This basically tells Oracle how to match the data in a particular row in B with the data in a particular row in C with the data in a particular row in D.
