Saving a SQL query in xml

I'm writing a program that reads in an xml file that is storing some SQL queries. The user can then select a query and it will run the query on the database and present them with the results. I am running into a problem though and I have narrowed it down to this query:
SELECT NAME, (PO.AMOUNT-P.AMOUNT) AS BALANCE
FROM VENDOR V, PURCHASEORDER PO, PAYMENTS P
WHERE V.VENDORID = P.VENDORID AND PO.PONUM = P.PONUM AND P.AMOUNT < PO.AMOUNT
My best guess as to what is going on is that the less than sign is causing some problem. The error NetBeans is giving me when I run the program is as follows:
SEVERE: [Fatal Error] :109:164: The content of elements must consist of well-formed character data or markup.
SEVERE: org.xml.sax.SAXParseException: The content of elements must consist of well-formed character data or markup.
Is anyone aware of anything else in the query that might be causing this to happen?

[FAQ: What are the special characters in XML?|http://xml.silmaril.ie/authors/specials/]... You need to escape all of them, or use something which does so already such as [apache commons|http://commons.apache.org/] (IIRC).

Can we generate the output of SQL Query in XML format ..

Hi Team,
Can we generate an XML doc for an SQL Query.
I've seen in SQL Server 2000.It is generating the output of an SQL Query in xml format.
select * from emp for xml auto
The output looks like
<emp EMPNO="7369" ENAME="SMITH" JOB="CLERK" MGR="7902" HIREDATE="1980-12-17T00:00:00" SAL="2800" DEPTNO="20"/><emp EMPNO="7370" ENAME="SMITH" JOB="CLERK" MGR="7902" HIREDATE="1980-12-17T00:00:00" SAL="2800" DEPTNO="10"/>

Just a little bit of short hand.
Get the XML out of your database, via HTTP
Of course the easiest method is just to return an XMLType from a stored procedure and let the calling routine figure out what to do with it. Instead
of that way though, I'll show you how to do it via HTTP. It's all completely built into 10g and is super easy to use.
CREATE OR REPLACE VIEW emps_and_depts AS
SELECT e.employee_id AS "EmployeeId",
e.last_name AS "Name",
e.job_id AS "Job",
e.manager_id AS "Manager",
e.hire_date AS "HireDate",
e.salary AS "Salary",
e.commission_pct AS "Commission",
XMLFOREST (
d.department_id AS "DeptNo",
d.department_name AS "DeptName",
d.location_id AS "Location"
) AS "Dept"
FROM employees e, departments d
WHERE e.department_id = d.department_id
Some people hear web and immediately start salivating about security issues. Let me address that quickly. Just because you have the HTTP and/or
FTP servers running in the database, that does not mean you have a security problem. For one, I would hope your databases are behind a firewall.
Second, with the correct architecture (DMZ, app servers, etc) you can make this data available outside the firewall fairly transparently and third,
just because it's on the web does not mean the data MUST be available on the internet. This is a good way to make your data available on your
intranet. If you are worried about people INSIDE your firewall, that still doesn't preclude web based access. Follow Oracle security guidelines.
Before I show you how to get to your data, let's talk about URLs and URIs. A URL is a Uniform Resource Locater and URI is a Uniform Resource
Identifier. A URL is the way you would identify a document on the net, i.e. http://www.oracle.com is a URL. A URI is a more generic form of a URL.
Oracle supports three types of URI: HTTPURIType - basically a URL (which would be like the URL above), XDURIType - a pointer to an XDB resource
(usually an XML document but can be other objects), and DBURIType - a pointer to database objects.
It's the DBURIType that we're going to concentrate on here. The DBURIType let's us reference database objects using a file/folder paradigm. The
format for a DBURI is /oradb/<schema>/<table>. Oradb is shorthand for the database; it is not the database name or SID. My database is named XE
but I still use oradb in the DBURI. For example, the view we created above is in my XE database, is owned by HR (at least in my case) and is called
EMPS_AND_DEPTS. This can be referenced as /oradb/HR/EMPS_AND_DEPTS.
If the view had many rows and you wanted only one of them, you can restrict it by including a predicate. The documentation for XDB has a great
write up on Using DBURIs.In our case, we are going to write out the entire document. Now that you understand that the DBURI is a pointer to
objects in our instance, we can use that to access the data as a URL.
The format for the URL call is http://<machinename>:<port>/<DBURI>
In my case, my XE database is running on a machine called mach1 and is listening on port 8080. So to see the view we created above, I open my
browser and navigate to: http//mach1:8080/oradb/HR/EMPS_AND_DEPTS
The created URL will be as http//mach1:8080/oradb/PUBLIC/EMPS_AND_DEPTS
If your database is set up correctly and listening on port 8080 (the default), your browser should ask you to login. Login as the user who created the
view (in my case HR). You should now get an XML document displayed in your browser.
And that's it. It doesn't get much simpler than that. If you get rid of the descriptive text above, it basically comes down to:
Create a table or view
Open your web browser
Enter a URL
Enter a user ID and password
View your XML
If you notice, Oracle formatted the data as XML for us. Our view returns scalar columns and an XML fragment called Dept. Oracle formatted the
return results into an XML format.
And as a side note, if you look closely, you'll see that my URL has PUBLIC where I said to put HR. PUBLIC is a synonym for all objects that your
logged in user can see. That way, if your user has been granted select access on many schemas, you can use PUBLIC and see any of them.

LIKE operator is not working in SQL Query in XML file

Hi Gurus,
LIKE operator is not working in SQL query in XML template.
I am creating a PDF report in ADF using Jdeveloper10g. The XML template is as follows
<?xml version="1.0" encoding="WINDOWS-1252" ?>
<dataTemplate name="catalogDataTemplate" description="Magazine
Catalog" defaultPackage="" Version="1.0">
<parameters>
<parameter name="id" dataType="number" />
<parameter name="ename" dataType="character" />
</parameters>
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[
SELECT ename, empno, job, mgr from EMP where deptno=:id and ename LIKE :ename || '%']]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="EmployeeInfo" source="Q1">
<element name="EmployeeName" value="ename" />
<element name="EMPNO" value="empno" />
<element name="JOB" value="job"/>
<element name="MANAGER" value="mgr" />
</group>
</dataStructure>
</dataTemplate>
if i pass the parameter value of :ename from UI, it doesn't filter. But if I give ename = :ename it retrieves the data. Can anyone help me why LIKE operator doesn't work here?
Appreciate your help,

Hi
Well for a start, you are doing some very strange conversions there. For example...
and to_char(a.msd, 'MM/DD/YYYY') != '11/11/2030'
and to_char(a.msd, 'MM/DD/YYYY') != '10/10/2030'If a.msd is a date then you should e converting on the other side ie.
and a.msd != TO_DATE('11/11/2030', 'MM/DD/YYYY')
and a.msd != TO_DATE('10/10/2030', 'MM/DD/YYYY')Also, you may want to take into consideration nothing being input in :P2_ITEM_NUMBER like this...
AND INSTR(a.item_number,NVL(:P2_ITEM_NUMBER,a.item_number)) > 0Is item number actually a number or char field? If it's a number, you want to explicitly convert it to a string for using INSTR like this...
AND INSTR(TO_CHAR(a.item_number),NVL(TO_CHAR(:P2_ITEM_NUMBER),TO_CHAR(a.item_number))) > 0?

Inst. XDK on Oracle 8.05, just to transform sql-query in xml

hi,
id like to install xdk to use xsu to transform a sql query in xml.
(i didnt find a way to download xsu without xdk)
i4ve oracle 8.0.5 but i only find 9i-xdk-(pl/sql) - is this correct?
what do i have to notice when i install
this package with my orace-ver?
thanks :o)

XDK 9.x is not only for Oracle9i Database. You can download the
9.0.2B XDK for Java and use XSU [or xsu12.jar(xsu11.jar)].

Invoking a process to return a SQL query as XML results in empty XML tag (but testing the SQL works)

I have a process that runs a SQL query and returns the results as XML. When I test the query in the Process Properties tab in Workbench it appears to execute just fine. I can also test the XML information and see that the results are coming back correctly. But when I invoke the process I get an emtpy XML tag with no results. Recording the invocation and playing back the recording doesn't tell me anything useful. Has anyone ever seen this issue before? I don't understand why everything within the process seems to bring back results just fine but invoking it returns nothing.

Unfortunately I am not the admin for our LiveCycle instance and do not have access to the server logs (long story). I also am not authorized to share any LCA files for this project. Thanks though.

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.

Sql query, from xml to nested table

Hello!
I have DB table: my_table
It has 2 fields: file_id and file_data (it's clob with xml)
I need to write query that returns info from xml using nested table (Oracle v.9)
The number of rows witch will return query must be equal to number of files (file_id)
Structure of XML:
<?xml version = "1.0" encoding = "utf-8"?>
<head>
<AAA v1="a" v2="b">
<BBB p1="1" p2="2"/>
<BBB p1="3" p2="4"/>
</AAA>
<AAA v1="c" v2="d">
<BBB p1="5" p2="6"/>
<BBB p1="7" p2="8"/>
<BBB p1="9" p2="0"/>
</AAA>
</head>
I have query, witch works! but not optimally! each CLOB scaned 3 times - I want to scan it once!
SELECT an.file_id,
CAST(MULTISET(SELECT extract(VALUE(val2),'//@v1').getStringVal() v1,
extract(VALUE(val2),'//@v2').getStringVal() v2,
CAST(MULTISET(SELECT extract(VALUE(val3),'//@p1').getStringVal() p1,
extract(VALUE(val3),'//@p2').getStringVal() p2,
FROM TABLE (XMLSEQUENCE(XMLTYPE(an.file_data).EXTRACT('/head/AAA/BBB[../@v1='||extract(VALUE(val2),'//@v1').getStringVal()||']'))) val3) AS T_VAL3) info
FROM TABLE (XMLSEQUENCE(XMLTYPE(an.file_data).EXTRACT('/head/AAA'))) val2) AS T_VAL2) head
FROM (SELECT olr.*
FROM my_table olr,
TABLE (XMLSEQUENCE(XMLTYPE(file_data)).EXTRACT('/head'))) val1) an
PLEASE, help me to rewrite this query!

I assume you're using nested objects like these to hold the result?
create type t_val3_rec as object ( p1 number, p2 number );
create type t_val3 as table of t_val3_rec;
create type t_val2_rec as object ( v1 varchar2(30), v2 varchar2(30), c1 t_val3 );
create type t_val2 as table of t_val2_rec;
/then this query should work :
SELECT t.file_id
     , CAST(
         MULTISET(
           SELECT extractvalue(value(x1), '/AAA/@v1')
                , extractvalue(value(x1), '/AAA/@v2')
                , CAST(
                    MULTISET(
                      SELECT extractvalue(value(x2), '/BBB/@p1')
                           , extractvalue(value(x2), '/BBB/@p2')

All of my table columns are NUMBER/VARCHAR2 data types and the table is also NOT a XML Type. Please let me know the solution.
Thanks.

How to get the metadata (in xml format) of all the fileds in SQl query ?

Good day ,
I am using the dbms_xmlgen.getXMLfunction to get the result of any query in xml format.
With this XML I also want the metadata information about all the fields used in the query (passed to getXML function). Is it possible and how can I achieve this.
I tried to Google it but couldn't find any solution , it's easy to do it in java where I can get the resultset meta data from the resultset but I have to do it in Oracle function since I want the result in xml format and want to use the oracle XML API.
You may think why I need metadata , the reason is the application will later use this information to sort the data contained in these fields according to their data type provided to.
Regards
Sajjad Ahmed Paracha

Hi,
Please always say which version of Oracle you're using (SELECT * FROM v$version).
With this XML I also want the metadata information about all the fields used in the query (passed to getXML function). Is it possible and how can I achieve this.It is possible but with a bit of effort.
I would use DBMS_SQL utility to parse the query, extract each column's description and then build a METADATA element with the required information.
Here's an example (11g) :
DECLARE
v_query      varchar2(30) := 'select * from scott.emp';
v_cur        integer;
v_desc_tab   dbms_sql.desc_tab;
v_col_cnt    number;
v_col_lst    varchar2(4000);
v_xml_query varchar2(32767);
xml_metadata_coll xmlsequencetype := xmlsequencetype();
xml_metadata      xmltype;
res          clob;
BEGIN
v_cur := dbms_sql.open_cursor;
dbms_sql.parse(v_cur, v_query, dbms_sql.native);
dbms_sql.describe_columns(v_cur, v_col_cnt, v_desc_tab);
dbms_sql.close_cursor(v_cur);
for i in 1 .. v_col_cnt loop
    if i > 1 then
      v_col_lst := v_col_lst || ', ';
    end if;
    v_col_lst := v_col_lst || v_desc_tab(i).col_name;
    xml_metadata_coll.extend;
    select xmlelement("COLUMN"
           , xmlattributes(v_desc_tab(i).col_name as "name")
           , xmlforest(
               case v_desc_tab(i).col_type
                 when 1   then 'VARCHAR2'
                 when 2   then 'NUMBER'

</ROOT>A couple of comments :
<li> I handle only four datatypes here (VARCHAR2, NUMBER, DATE, TIMESTAMP). Of course you can add more.
The list of Oracle Type Number is available here : http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements001.htm#i54330
Starting with 11g (not sure which release), DBMS_SQL package also declares these numbers through named constants.
<li> I don't use DBMS_XMLGEN in this example. Instead I rebuild the query using SQL/XML functions and the list of columns that's just been described.

Xml parsing error while selecting whole result set for sql query

Hi All,
I am having xml parsing error while selecting whole query result set. The data is coming fine for default result set of 50 rows.
My exception is below.
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00234: namespace prefix "xsi" is not declared
Error at line 1
ORA-06512: at "SYS.XMLTYPE", line 254
ORA-06512: at line 1
*31011. 00000 - "XML parsing failed"*
**Cause: XML parser returned an error while trying to parse the document.*
**Action: Check if the document to be parsed is valid.*
My sql query is below that is giving results for default result set of 50 rows.
select extract(xmlType(clob_xml_colm_name), '//v2:node1//childnode/text()','xmlns:v2="namespace_url"').getStringVal() from table_name
My sql developer version is below.
Java(TM) Platform     1.7.0_04
Oracle IDE     3.1.07.42
Versioning Support     3.1.07.42
My database version is below.
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit
Please could any one help me urgently as the sql query is supposed to be correct as it is returning query results, but the problem happening when i try to select whole result set.
Thanks and regards,

What does the XML look like? It appears that some of the supposed XML stored as a CLOB is not really valid XML. Find the row in the table that is causing your issue and review the "XML" in it.

SQL Server 2012 Management Studio: XML XQuery-query the XML Blob using CTE: How to specify the coorelation name in bulk rowset?

Hi all,
I just started doing the XML Xquery programming in my SQL Server 2012 Management Studio. I executed the following code:
--query the XML Blob using a CTE (pulling from the XML file each time) Products
WITH XmlFile (Contents) AS (
SELECT CONVERT (XML, BulkColumn)
FROM OPENROWSET (BULK 'H:\Products.xml', SINGLE_BLOB) ) AS XmlData
SELECT *
FROM XmlFile
GO
I got the the following Msg:
Msg 491, Level 16, State 1, Line 4
A correlation name must be specified for the bulk rowset in the from clause.
How can I specify the correction name for the bulk rowset in my project?
Please kindly help, advise and respond.
Thanks in advance,
Scott Chang

Hello Scott,
You have to assign a table alias for the OPENROWSET =>
--query the XML Blob using a CTE (pulling from the XML file each time) Products
WITH XmlFile (Contents) AS (
SELECT CONVERT (XML, BulkColumn)
FROM OPENROWSET (BULK 'H:\Products.xml', SINGLE_BLOB) AS MyXML ) AS XmlData
SELECT *
FROM XmlFile
GO

Can we run SQL query on a XML file?

Hi All
I have an XML document which stores data of a table.
My requirement is to retreive data from this XML document by firing SQL
query.
i.e "SELECT * FROM EMP" should give me the data from the EMP.XML file
whose name is the table name.
Does Oracle provide this feature to retreive data from an XML document
by issuing the same SQL statement that is used in Database?
Any pointer for this requirement is highly appreciated.
Thanks in advance..

Oracle XSU: oracle.xml.sql.query.OracleXMLQuery is not recognized

Hi, there!
I've got a problem when tryed to use Oracle XSU (xml-sql utility to generate xml). My simple java application works fine using XSU. But when I created session stateless bean I've got an EJBException regarding this
line:
oracle.xml.sql.query.OracleXMLQuery qry = new oracle.xml.sql.query.OracleXMLQuery(conn, commandSQLStatement);
It doesn't recognize OracleXMLQuery class as I've got in dump. So my classpath includes original location of that utility and Oracle parser.
I really appreciate for any help.
Thanks.
strXML = qry.getXMLString();

Patricia,
Did you go through the link
Re: XML SQL Utility
You have to put xsu12.jar in the lib directory of the jdev.
xsu12.jar is in the lib directory of the XDK installation.
You can download XDK from
http://www.oracle.com/technology/tech/xml/xdk/software/prod/xdk_java.html
Just download the XDK kit, get the xsu12.jar from the lib directory and put in the lib directory of the jdev.
