XMLType.Transform () / namespace
HelloMy server is Oracle9i Enterprise Edition Release 9.2.0.6.0.
I'm transforming an XML fragment of entry into a fragment of XML output using XMLType.Transform ().
This works well when no namespace attribute is present in the input XML code.
For example:
< < < code > > >
DECLARE
LXML XMLTYPE: = XMLTYPE ("< movement >
< NOTF_ID > 1022914300 < / NOTF_ID >
< SNUN_CDE > BE40309029-0101 < / SNUN_CDE >
< ANML_REF_NBR > 6 43301900 < / ANML_REF_NBR >
< NOTP_CDE > MMDPR < / NOTP_CDE >
< OCR_DTE > 2008 - 11 - 05T 00: 00:00 < / OCR_DTE >
(< / movement > ');
lxsl XMLTYPE: = XMLTYPE ("< xsl: stylesheet version ="1.0"xmlns: xsl =" http://www.w3.org/1999/XSL/Transform">)
< xsl: output method = "xml" / >
< xsl: template match = "Movement" >
< movement >
< xsl: Copy - of select="./NOTF_ID"/ >
< xsl: Copy - of select="./ANML_REF_NBR"/ >
< xsl: Copy - of select="./OCR_DTE"/ >
< / movement >
< / xsl: template >
(< / xsl: stylesheet > ');
lstr VARCHAR2 (4000);
BEGIN
LXML: = lxml. Transform (lxsl);
-show the result
lstr: = lxml.getStringVal ();
IN all, LENGTH (lstr) > 0
LOOP
DBMS_OUTPUT. Put_line (substr (lstr, 1, 255));
lstr: = SUBSTR(lstr,256);
END LOOP;
END;
/
< < < code > > >
The result is exactly what I want it to be:
< < < output > > >
< movement >
< NOTF_ID > 1022914300 < / NOTF_ID >
< ANML_REF_NBR > 6 43301900 < / ANML_REF_NBR >
< OCR_DTE > 2008 - 11 - 05T 00: 00:00 < / OCR_DTE >
< / movement >
< < < output > > >
However, when a namespace attribute is present on the element root entry XML, the result of the transformation, not what want to:
< < < code > > >
DECLARE
LXML XMLTYPE: = XMLTYPE ("< movement xmlns =" http://some_url">)
< NOTF_ID > 1022914300 < / NOTF_ID >
< SNUN_CDE > BE40309029-0101 < / SNUN_CDE >
< ANML_REF_NBR > 6 43301900 < / ANML_REF_NBR >
< NOTP_CDE > MMDPR < / NOTP_CDE >
< OCR_DTE > 2008 - 11 - 05T 00: 00:00 < / OCR_DTE >
(< / movement > ');
lxsl XMLTYPE: = XMLTYPE ("< xsl: stylesheet version ="1.0"xmlns: xsl =" http://www.w3.org/1999/XSL/Transform">)
< xsl: output method = "xml" / >
< xsl: template match = "Movement" >
< movement >
< xsl: Copy - of select="./NOTF_ID"/ >
< xsl: Copy - of select="./ANML_REF_NBR"/ >
< xsl: Copy - of select="./OCR_DTE"/ >
< / movement >
< / xsl: template >
(< / xsl: stylesheet > ');
lstr VARCHAR2 (4000);
BEGIN
LXML: = lxml. Transform (lxsl);
-show the result
lstr: = lxml.getStringVal ();
IN all, LENGTH (lstr) > 0
LOOP
DBMS_OUTPUT. Put_line (substr (lstr, 1, 255));
lstr: = SUBSTR(lstr,256);
END LOOP;
END;
/
< < < code > > >
This translates to the concatenation of all the item values in the input XML code:
< < < output > > >
43301900MMDPR2008 1022914300BE40309029-0101BE 6-11 - 05T 00: 00:00
< < < output > > >
My question is: how to make the style sheet so that the attribute for namespace in the XML of entry is either ignored or simply copied in the XML output?
Any suggestions?
Thank you
Jaap Kool
I knew that my first reaction was made of namespace on the elements copied over but he did show you how to use namespaces and you allowed to go further along your solution. Here's a way (others may exist) to remove the copy of empty items above
The reason behind using text() is therefore that
Hope that helps.

An unescaped ampersand still causes LPX-00242 in xmltype.transform
Running Oracle Database 11 g Enterprise Edition Release 11.1.0.7.0 - 64 bit Production
Collect web form and recovery through SQLX functions then transformed into html and plain text documents. If the '&' entered... functions SQLX is not immune to "& amp;"... but the LPX-00242 error is always triggered when sending to xmltype.transform.
A simple test case:
the code above throws this exception:set define off; declare l_xsl xmltype; l_xml xmltype; begin l_xsl := xmltype('<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:template match="/"> Hello <xsl:value-of select="//name"/> </xsl:template> </xsl:stylesheet>'); l_xml := xmltype('<test><name>Jane&John Doe</name></test>'); dbms_output.put_line(l_xml.transform (l_xsl ).getclobval ()); end;

Hello Jane & amp; amp; John Doe
any reason why the SQLX function escape is not enough and I need to double-escape it? The working version ideal, since I now have to decode the reference entity to him is not character, otherwise the code entity reference appears in the content.
Published by: pl_sequel on 7 Sep 2011 14:12[4] all that requires the double escapement in a part of the xml, but not the other is suspect.
Okay, but see my example again (tested in 11.2.0.1), no double-escaping used, and the output is correct.
The tip of the double escapement is just what OP found as a workaround for his code, but then it is equivalent to the method = "xml" in the first place (as you showed some post after).

Published by: jortri on June 25, 2010 11:37The differences are due to the fact that Oracle 10 g went in accordance with W3C.
If the XMLType constructor complains about a missing namespace declaration, which is XML not valid according to the W3C.That being said, you can greatly simplify the code:

Transform XMLTYPE works differently in Oracle 10.1 and 11.2
We are migrating our applications to Oracle 10.1 g to 11.2 g. We have a number of routines of PL/SQL that transform the incoming/outgoing XML using the XMLType Transform method. XSLT transformations that we use doesn't seem to work at 11.2. For example, the code below is a simplification of what we do. This code example uses the coded entrance to irreversibly and xslt to illustrate this point. The same code has very different results when operating in 10.1 and 11.2. In 10.1, the work of transformation. He was also using files in an xml tool. 11.2, none of the input XML is transformed. The only exit is the extra < sd:StandardBusinessDocument... which is hard-coded in the xslt as a wrapper.

Q: any ideas? Are there changes in 11g 11.2 requiring major changes to xslt?
We have a lot of rewriting for this if we can't get this to work!
Hi Eduardo,
Report it as a bug to the Support of Oracle.
The problem lies in the function namespace - uri (): comparison with an empty string is not resolved properly, so no node is still selected in the first xsl: for each.
If you need a workaround solution, there are some that you can test:
(1) if the entry documents are actually in no namespace (for example, in your example), delete all occurrences namespace - uri () of the style sheet.
(2) in the opposite direction, you can give your document of entry a dummy namespace and now referenced in the style sheet. The namespace - uri () test will work in this case.
(3) replace the occurrences of namespace - uri () by a somewhat more elaborate test that will handle namespace empty in particular, for example:
(namespace-uri () = $nsuri or (not ($nsuri) and not (namespace - uri ()))
Given that you work with generated style sheets, I understand that none of the options above are really satisfactory.
If I had to work around the problem, I would probably go with the 2nd option which involves a smaller amount of refactoring.

Best practices to generate an output HTML to send by mail
Hello
In our 11g application we are generating a mail plaintext database plsql, with little data retrieved by a query.
Now, mail is growing complex, so we´d like to put a little more shaped (an html table, I guess).
I see a few solutions:
1 crap: create html with concat string and a good ol' ' cursor for loop.
2. get the result of the query in xml format and apply an xsl stylesheet to generate the html string. Cleaner, but it's worth? How can you get the HTML?
Can you suggest me a good practice to achieve this? Any oracle package?
We currently use the #2 option in one of our applications, and yes it is worth.
This approach separates data layout and allows different formats to come from the same source, for example html, text, csv, and formats the same oox (.xlsx).
Any oracle package?

It is a sequel to this discussion:
where it says towards the end:
Question 2. If there are any xml function which can update the name of the tag. as in the example above I need to change the < home_address > as < permanant_address >
No, not directly.
XQuery Update Facility, which is implemented in the 11.2.0.3 version, can do.
For lower versions, you will need to use XSLT or XQuery.
I, too, use 11.1 and I'd like to know how to turn an xmltype stored in a table using XSLT or XQuery. I would be grateful if someone could give an example of one or both.
Thank you
Morgan
4. so, I want to know how to do something like this (pseudocode);
update books
Set object_value =
XMLTRANSFORM (object_value, xsl)
where XMLExists ('/wrapper')
Is this possible?
What happens when you try?
Yes, it is possible:
SQL> var xsl clob SQL> SQL> begin 2 :xsl := '
Although I would not want to use XSLT in this specific example, XQuery is easier and better optimized:
SQL> roll Rollback complete. SQL> SQL> update books 2 set object_value = 3 xmlquery( 4 '/wrapper/book' 5 passing object_value 6 returning content 7 ) 8 where xmlexists('/wrapper' passing object_value); 2 rows updated. SQL> select count(*) from books where xmlexists('/book' passing object_value) ; COUNT(*) ---------- 4Choose between XQuery and XSLT to transform an XML document really depends on the type of operations.
For example, I tend to use XSLT when processing needs of recursion, such as the removal of one space names default or delete/insert some nodes "deeply" in the document (if I can't use XQuery Update of course).

Excerpt from XMLType problem with different namespaces
Hello
I need some advice on how to extract the child element to the XML fragment where the parent namespace differs child name space. I have done the broad research and I've tried several options but have had no success.
This is fragment plsql sample
vTheXML: = XMLType ("< GeneratedDocument xmlns ="http://tempuri.org/"> ")
" < file_name xmlns =" http://services.DPM.com.au/intelledox/ "> Test.pdf < / Filename > .
(< / GeneratedDocument > ');
Below successfully returns a GeneratedDocument element (IE any fragment)
vExtractXML: = vTheXML.extract ('/ GeneratedDocument ',' xmlns = "http://tempuri.org/"');
But none of below works. They return null. I do not know how to represent the different namespaces in the function call retrieves XMLType
vExtractXML: = vTheXML.extract ('/ GeneratedDocument/filename ',' xmlns = "http://services.dpm.com.au/intelledox/"');
vExtractXML: = vTheXML.extract ('/ GeneratedDocument/filename ',' xmlns = "http://tempuri.org/"xmlns ="http://services.dpm.com.au/intelledox/"');
vExtractXML: = vTheXML.extract ('/ GeneratedDocument/filename ',' xmlns = "http://tempuri.org/"');
Below works, but would ideally use more precise criteria of XPath
vExtractXML: = vTheXML.extract ("/ / filename ',' xmlns ="http://services.dpm.com.au/intelledox/"'");
Thank you
Hello
Of course, you cannot declare two namespaces by default in the namespace mapping, use at least a prefix to distinguish them:
vExtractXML: = vTheXML.extract ('/ GeneratedDocument / ns1:FileName ',' xmlns = "http://tempuri.org/" xmlns:ns1 = "http://services.dpm.com.au/intelledox/"');
(NB: extract and extractvalue, etc. have been deprecated in 11.2)

exec dbms_xmlschema.deleteSchema(schemaURL => 'Parameters4.xsd'); declare v_xsd xmltype := xmltype('<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:oraxdb="http://xmlns.oracle.com/xdb" xmlns = "http://www.cognera.com" targetNamespace = "http://www.cognera.com"> <xs:element name="Parameters" oraxdb:SQLName="Parameters" oraxdb:SQLType="Parameters"> <xs:complexType oraxdb:SQLType="Parameters"> <xs:sequence> <xs:element name="Param1" type="xs:string" oraxdb:SQLName="Param1" oraxdb:SQLType="VARCHAR2" /> <xs:element name="NestedItems" oraxdb:SQLName="NestedItems" oraxdb:SQLType="NestedItemsType"> <xs:complexType oraxdb:SQLType="NestedItemsType"> <xs:sequence> <xs:element name="NestedItem" type="NestedItemType" oraxdb:SQLName="NestedItem" oraxdb:SQLType="NestedItemType"/> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="NestedItemType" oraxdb:SQLType="NestedItemType"> <xs:sequence> <xs:element name="nParam1" type="xs:string" oraxdb:SQLName="nParam1" oraxdb:SQLType="VARCHAR2"/> <xs:element name="nParam2" type="xs:string" oraxdb:SQLName="nParam2" oraxdb:SQLType="VARCHAR2"/> <xs:element name="nParam3" type="xs:string" oraxdb:SQLName="nParam3" oraxdb:SQLType="VARCHAR2"/> </xs:sequence> </xs:complexType> </xs:schema> '); begin dbms_xmlschema.registerSchema(schemaURL => 'Parameters4.xsd', --this name is local to each ERS schema. schemaDoc => v_xsd, local => TRUE, genTypes => TRUE, --only want the types genbean => FALSE, genTables => TRUE, --not sure if I need this force => TRUE, owner => user); end; /The types created were:

CREATE OR REPLACE TYPE "Parameters" AS OBJECT ("@xmlns" VARCHAR2(4000), -- namespace attribute HACK "Param1" VARCHAR2(4000 CHAR),"NestedItems" "NestedItemsType")FINAL INSTANTIABLE /Putting it all together, I have:
DECLARE v_Parameters "Parameters"; v_xml xmltype; v_print_output clob; begin v_Parameters := "Parameters"('www.cognera.com', 'hello', "NestedItemsType"("NestedItemType"('one', 'two', 'three' ) ) ); v_xml := xmltype(xmlData => v_Parameters); select xmlserialize(document xmlquery('declare namespace soap = "http://www.w3.org/2003/05/soap-envelope"; declare namespace cognera = "http://www.cognera.com"; <soap:Envelope> <soap:Header/> <soap:Body> {/} </soap:Body> </soap:Envelope> ' passing v_xml returning content) as clob indent size=2 ) into v_print_output from dual; dbms_output.put_line(v_print_output); end;This generates:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> <soap:Header/> <soap:Body> <Parameters xmlns="www.cognera.com"> <Param1>hello</Param1> <NestedItems> <NestedItem> <nParam1>one</nParam1> <nParam2>two</nParam2> <nParam3>three</nParam3> </NestedItem> </NestedItems> </Parameters> </soap:Body> </soap:Envelope>
What I really want is:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:c="www.cognera.com"> <soap:Header/> <soap:Body> <c:Parameters> <c:Param1>hello</c:Param1> <c:NestedItems> <c:NestedItem> <c:nParam1>one</c:nParam1> <c:nParam2>two</c:nParam2> <c:nParam3>three</c:nParam3> </c:NestedItem> </c:NestedItems> </c:Parameters> </soap:Body> </soap:Envelope>
How can I do this without having to add to the namespace using the custom XQuery function?
Both outputs are semantically equivalent.
Why do you need one?

extraction of xmltype and excluding all the tags of the namespace?
Hi all
I am trying to extract the xmltype column in another xmltype column in another table.
Select xt.attachment_content, xt.attachment_type, xt.attachment_format
OF document_version dva.
XMLTABLE)
XMLNamespaces ('http://oracle.com/test1/1.0'),
"AttachmentList/attachment.
PASSAGE document_content
COLUMNS
attachment_content path of xmltype "content."
path of varchar2 (100) to attachment_type 'type,'
XT attachment_format varchar2 (100) path 'format')
This query returns results, BUT the content has tags and namespaces in the game too. I just want to return the content than ANY version of xml without xmlns: (xmlnamespaces) and etc.
Please help me how to do this.OK, thanks for the effort, however, this is not a test case from work, by far...
The input XML is not valid because you probably just copied the version without escape sequence and paste here.
The cuts you made in the XML load make invalid too.The query is not true either, syntax XMLNamespaces is bad, but also the XPath expression.
I understand that you want to present a simplified scenario based on but you are in fact wasting time by not giving something that we can run.
Now, if I have a query document_attachments table content column displays the results, but with all the tags of the namespace and etc.
As said, I doubt that the request you give will never recover anything, but that is a different problem.
What I would like to know because my first answer is why namespaces are a problem for you? They are part of the document and it is easy to deal with them once we know how to do it.
For example, this retrieve the value of the content as CLOB (plain text) and convert on the fly of XMLType:
INSERT INTO document_attachments (doc_id, content, type, format) SELECT dva.doc_id , xmlparse(document xt.attachment_content) as content , xt.attachment_type as type , xt.attachment_format as format FROM document_version dva , XMLTable ( XMLNamespaces(default 'http://optimal.com/SP/2/RandPCommon/DocumentStore/GatewayRequestStore/1.0') , 'AttachmentList/attachment' PASSING document_content COLUMNS attachment_content clob path 'content' , attachment_type varchar2(100) path 'type' , attachment_format varchar2(100) path 'format' ) xt ;Now, the contents column is:
test Is this OK so far?
What do you do next with the content column?
Yet once there is no need to remove any namespace, or if he really exists, please explain what requirement business dictates who and how the attachment must be treated thereafter.Published by: odie_63 on May 26, 2012 19:07

XmlType extractValue with namespace throw exception "invalid token".
Hello. I have XML stored as XMLTYPE and with content, such as:

Schema validation fails on the transformed XML document
OK, this is weird.
I get XML files that are supposed to conform to a given XSD. There are dozens of different parties who send these files. To be more precise, I refer to the Ontario Energy Board (OEB) PIPE Documents.
I found that at least one sender sends invalid files. I can't that fixes to the source, so I'm working around that.
for example
Oracle is not like this:<?xml version="1.0" encoding="UTF-8"?> <PIPEDocument xmlns="http://www.oeb.gov.on.ca" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.oeb.gov.on.ca/ PIPEDocument.xsd" Version="4.0" DocumentReferenceNumber="xxx" CreationDate="20110825100008000ES"> <MarketParticipantDirectory> <Sender> ...
OK, so to work around this problem, before schema validation, I apply an XSLT transformation to clean the top-level element:ORA-31154: invalid XML document ORA-19202: Error occurred in XML processing LSX-00344: namespace values "http://www.oeb.gov.on.ca" and "http://www.oeb.gov.on.ca/" differ
Nice: the fact that it is intended for:<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.oeb.gov.on.ca"> <xsl:output method="xml" indent="no"/> <xsl:template match="/"> <xsl:copy> <xsl:apply-templates/> </xsl:copy> </xsl:template> <xsl:template match="*"> <xsl:if test="local-name() = name()"> <xsl:element name="{local-name()}"> <xsl:apply-templates select="@*|node()"/> </xsl:element> </xsl:if> </xsl:template> <xsl:template match="@*"> <xsl:if test="local-name() = name()"> <xsl:attribute name="{local-name()}"> <xsl:value-of select="."/> </xsl:attribute> </xsl:if> </xsl:template> </xsl:stylesheet>
If I now the schema validate the above transformed XML, then it validates OK.<?xml version="1.0" encoding="UTF-8"?> <PIPEDocument xmlns="http://www.oeb.gov.on.ca" Version="4.0" DocumentReferenceNumber="50520110825080908VA0001.EBT" CreationDate="20110825100008000ES"> <MarketParticipantDirectory> <Sender> ...
Large? No, if I try to turn on the fly (i.e. without first transformation and followed by reading in the transformed data from the file), I get a strange error:
declare v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML()); v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; begin if v_xml.isSchemaValid(v_xsd_name) = 1 then dbms_Output.put_line('valid'); else dbms_Output.put_line('invalid'); --in order to get specific error info for a non-schema message need to convert the XML to schema based v_xml := v_xml.createSchemaBasedXML(v_xsd_name); v_xml.schemaValidate(); end if; end; /
Exsqueeze me? What element in the schema?ORA-31043: Element '' not globally defined in schema ''
The transformation itself works very well. Specifically, if I run the following:
... I get the desired result. Of course, if I save the result file and validate the fact that it works:select xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML()).getclobval() from dual;
I would like to join example XML file, but it contains customer data so I can't do that. I would fix the XSD but it is the nest of a rat of 50 XSD with includes and a 300 script online registration scheme, so I can't do that.declare v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604_manually_saved.xml'), 0); v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; begin if v_xml.isSchemaValid(v_xsd_name) = 1 then dbms_Output.put_line('valid'); else dbms_Output.put_line('invalid'); --in order to get specific error info for a non-schema message need to convert the XML to schema based v_xml := v_xml.createSchemaBasedXML(v_xsd_name); v_xml.schemaValidate(); end if; end; /
What I'm missing here?
Looks like an Oracle bug for me at this isSchemaValid binds to a beginning of the XML instance and not to the instance transformed.
thoughts?

Published by: Pollocks01 on October 18, 2011 16:11Hello
Looks like an Oracle bug for me at this isSchemaValid binds to a beginning of the XML instance and not to the instance transformed.
That wouldn't be surprising. There are "few" bugs on the XSL transformation.
Here's a recently posted: {: identifier of the thread = 2245703}The solution was to serialize the output and analyze again.
So, what you describe on 'reading of a works file' makes me think it's the same kind of problem.You can also view the contents of the variable just after that:
v_xml := v_xml.createSchemaBasedXML(v_xsd_name);?

Adding namespace to the XML output
Hello
I have a requirement to generate an XML document for the columns in the table. I use DBMS_XMLgen.getXML inside my procedure to get the XML document.
The result I get after my procedure is:
<? XML version = "1.0"? >
< EMP >
< EMPLOYEE_NO > 000017 < / EMPLOYEE_NO >
ASSETS of < EMPLOYEE_STATUS > < / EMPLOYEE_STATUS >
Mini < NAME_LAST > < / NAME_LAST >
< NAME_FIRST / >
< / EMP >
But I also need to prefix and uri of namespace in the xml output. Is it possible to add the prefix and namespace uri to the xml output.
So what I need, is something like below one:
<? XML version = "1.0"? >
< xs:EMP > xmlns: out = "http://xmlns:out="http:/example.org/ver1.0/ThisISTest#">
< xs:EMPLOYEE_NO > 000017 < / xs:EMPLOYEE_NO >
ACTIVE < xs:EMPLOYEE_STATUS > < / xs:EMPLOYEE_STATUS >
Mini < xs:NAME_LAST > < / xs:NAME_LAST >
< xs:NAME_FIRST / >
< / xs:EMP >
Any solutions or examples of code on it would be a great help.
Thanks in advance.Strange...
OK, back to the basics:

Cannot open the schema of the source on the Transformation of the opening
I get an error when I opened a transformation in my composite SOA in JDeveloper 12.1.3.0.0.
The error indicates "can't open the source schema:" "WSDLException: faultCode = access to this wsdl file oramds:/apps/company/ABCS/wsdl/CRUD_Item_ABCS_prov.wsdl problem: CachedWSDLReader readWSDL WIthExtensionRegistry returned NULL definition in the WSDL analysis"»»
I tried to restart JDeveloper and remove the directory with the same result .data.
Thank you

Hi Tom,
Check if the WSDL file is appropriately in the right schema locations and targetNamespace is correct.
Suggest that you copy the WSDL file in the project folder and check to see if the problem still persists. It could be a problem with namespaces. It will be useful.

How to get a list of the methods and functions to use in the Transformation
I am developing a transformation to apply the schema of a table in the relational model according to its type of classification. I was able to do this, but I have a doubt, in other words, how get the name of the first additional classification type, listed in the dropdown list of "Selected" of the "additional part" of the section "Types of Classification" of the table "Properties".
This is the code that I'm working on:
tables = model.getTableSet () .toArray ();
for (var t = 0; t < tables.length; t ++) {}
table = table [t];
rating = table.getAdditionalClassificationTypes () .toArray ();
SchemaName = ";
{if (rating. Length = 0)}
SchemaName = table.getClassificationType ();
} else {}
for (var s = 0; s < classif.length; s + +) {}
{if (rating [s]! = table.getClassificationType ())}
SchemaName = rating [s];
}
}
}
table.setSchema (schemaname);
}
The problem lies on the fact that I am able to get the ID of the Type of ranking, but not it's name...
I was wondering if there is some document that lists the methods, functions, and namespaces that I could use in Data Modeler?
Thanks in advance
