Xmltable information for meteo information

I have to obtain meteo information (es. weather) from this and store the values in a table ...
For example I would like to obatin the value "wx":"Light Rain"
http://www.classmeteo.it/REST-WS-Fluxes/resources/currentcond/currentByLocId/24040
Could someone help me with a query example?
Here is the http://www.classmeteo.it/REST-WS-Fluxes/resources/application.wadl
With google i did with this query ... but google is not yet available?
select *
from xmltable(
'/xml_api_reply/weather/current_conditions'
passing httpuritype('http://www.google.com/ig/api?weather=Cesano+Boscone').getXML()
columns condition varchar2(100) path 'icon/@data'
, temp_c number path 'temp_c/@data'
);

For example I would like to obatin the value "wx":"Light Rain"
http://www.classmeteo.it/REST-WS-Fluxes/resources/currentcond/currentByLocId/24040
Could someone help me with a query example?The method called returns a serialized JSON object. I doubt XMLTable is of any help in this situation.
If you're interested in a single value, try a regular expression.
Edit: well, you can do it with XMLTable without too much complexity provided the following is true :
- database release is 11.2
- JSON string is no more than 4000 bytes
- field value doesn't contain a comma
+(note that I didn't fully test the whole thing, as I couldn't get HttpUriType to work correctly)+
select trim('"' from field_name) as field_name
     , trim('"' from field_value) as field_value
from xmltable(
       'ora:tokenize(substring($json,2,string-length($json)-2), ",")'
       passing dbms_lob.substr(
                 httpuritype('http://www.classmeteo.it/REST-WS-Fluxes/resources/currentcond/currentByLocId/24040').getclob()
               ) as "json"
columns field_name varchar2(30) path 'substring-before(.,":")'
      , field_value varchar2(30) path 'substring-after(.,":")'

How to pass parameter into extract function (for XMLTYPE)

I have a table PROBLEMXML with XMLTYPE field xml_column. In this column there are several deffinitions for the problem. There is no max amount of deffinitions and it can be no definition at all. I need to return all definitions for every problem as a string wirh definitions separated by ";".
Query
SELECT extract(prob.Def,'/Definitions/Definition[1]/@var') || ';'|| extract(prob.Def,'/Definitions/Definition[2]/@var')
FROM PROBLEMXML j ,
XMLTABLE (
'/problem'
PASSING j.xml_column
COLUMNS probid VARCHAR (31) PATH '/problem/@id',
Def XMLTYPE PATH '/problem/Definitions') prob
where PROBLEM_ID =1;
returns exactly what I want a;m.
But
declare
my_var varchar2(2000) :=null;
n1 number;
n2 number;
begin
n1:=1;
n2:=2;
SELECT extract(prob.Def,'/Definitions/Definition[n1]/@var') || '|'|| extract(prob.Def,'/Definitions/Definition[n2]/@var') into my_var
FROM ETL_PROBLEMXML_STG_T j ,
XMLTABLE (
'/problem'
PASSING j.xml_column
COLUMNS probid VARCHAR (31) PATH '/problem/@id',
Def XMLTYPE PATH '/problem/Definitions') prob
where PROBLEM_ID =1;
dbms_output.put_line(my_var);
end;
returns NULL.
Is there is a way to pass parameter into extract function?

I need to return all definitions for every problem as a string wirh definitions separated by ";".In XQuery, there's the handy function "string-join" for that.
For example :
SQL> WITH etl_problemxml_stg_t AS (
2   SELECT 1 problem_id,
3 xmltype('<problem id="1">
4   <Definitions>
5    <Definition var="var1"></Definition>
6    <Definition var="var2"></Definition>
7    <Definition var="var3"></Definition>
8   </Definitions>
9 </problem>') xml_column
10   FROM dual
11 )
12 SELECT j.problem_id,
13         prob.probid,
14         prob.def
15 FROM etl_problemxml_stg_t j,
16       XMLTable(
17        'for $i in /problem
18         return element r
19         {
20          $i/@id,
21          element d { string-join($i/Definitions/Definition/@var, ";") }
22         }'
23        passing j.xml_column

25         probid varchar2(30) path '@id',
26         def    varchar2(100) path 'd'

XMLTable and strange results

I seem to be getting strange or at least unexpected results from the result of a PL SQL Query that uses XMLTable() in Oracle 11g1.
I have a table in Oracle that looks like this -
CREATE TABLE EPBNI_XML_TEST
(<blockquote>RRN VARCHAR(24) PRIMARY KEY,
ClipID VARCHAR2(27),
Lodgement XMLType</blockquote>)
XMLTYPE COLUMN Lodgement
STORE AS OBJECT RELATIONAL
ELEMENT "ConditionReportCreateRequest_1.xsd#ConditionReportCreateRequest_1";
Each XML Document stored in the XMLTYPE Column Lodgement is a little bit like this (simplified) -
<ConditionReportCreateRequest_1>
<blockquote>
<Content><blockquote><X-Report><blockquote><Report-Header><blockquote><RRN>123</RRN>
<Report-Type>type A</Report-Type>
<Status>status A</Status></blockquote></Report-Header></blockquote></X-Report></blockquote></blockquote><blockquote><blockquote><Y-Report></blockquote></blockquote><blockquote><blockquote><blockquote><Report-Header></blockquote></blockquote></blockquote><blockquote><blockquote><blockquote><blockquote><RRN>321</RRN>
<Report-Type>type B</Report-Type>
<Status>status B</Status></blockquote></Report-Header></blockquote></Y-Report></blockquote></Content></blockquote></ConditionReportCreateRequest_1>
Each Lodgement can have one or more reports in the XML document. What I am trying to acheive is getting a single list of the RRN, Report-Type and Status of every report, e.g.
RRN Report-Type Status
123 type A status A
321 type B status B
112 type A status A
113 type C status A
etc... etc....
My PL SQL and XQuery looks a bit like this -
SELECT xtab.RRN, xtab.ReportType, xtab.ReportStatus from
EPBNI_XML_TEST,
XMLTable('<blockquote>for $reportHeader in /ConditionReportCreateRequest_1/Content/child::element()/Report-Header return
<report>
$reportHeader/RRN,
$reportHeader/Report-Type,
$reportHeader/Status
</report></blockquote>'
PASSING LODGEMENT
COLUMNS
RRN VARCHAR2(24) PATH 'RRN',
ReportType VARCHAR2(1) PATH 'Report-Type',
ReportStatus VARCHAR2(10) PATH 'Status'
) xtab;
The problem is though that I seem to get only 1 result for each row of the table. I.e. if I have 9,000 rows in the EPBNI_XML_TEST table I only get 9,000 results. However I need one result for each report in each lodgement, probably closer to 18,000 results. Also all 9,000 results are the same - which I dont understand - i.e. all 9,000 are -
RRN Report-Type Status
123 type A status A
123 type A status A
123 type A status A
(upto 9000 identical result rows...)
What am I doing wrong or mis-understanding here?
Thanks Adam.

XMLTABLE / XQUERY performance

Hi all,
Below is a sample XML representing a spreadsheet :
<Table>
<Row>
<Cell><Data>1</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell><Data>B</Data></Cell>
<Cell Index="5"><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>2</Data></Cell>
<Cell Index="3"><Data>B</Data></Cell>
<Cell><Data>C</Data></Cell>
</Row>
<Row>
<Cell><Data>3</Data></Cell>
<Cell Index="3"><Data>B</Data></Cell>
<Cell Index="5"><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>4</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell><Data>B</Data></Cell>
<Cell><Data>C</Data></Cell>
<Cell><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>5</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell Index="4"><Data>C</Data></Cell>
<Cell><Data>D</Data></Cell>
</Row>
</Table>which should be interpreted as :
cols --> 1 2 3 4 5
         1 A B   D
         2   B C
         3   B   D
         4 A B C D
         5 A   C DAs you can see, for each row, empty cells are simply omitted in the document.
The next non-empty cell is then marked with an Index attribute representing its true position on the row.
My requirement is to query the document and access the values based on cells positions on the row.
Because of empty cells, Data values cannot be accessed by a simple xpath like "/Cell[n]/Data".
So I came up with the following :
WITH t AS (
select xmltype(
'<Table>
<Row>
<Cell><Data>1</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell><Data>B</Data></Cell>
<Cell Index="5"><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>2</Data></Cell>
<Cell Index="3"><Data>B</Data></Cell>
<Cell><Data>C</Data></Cell>
</Row>
<Row>
<Cell><Data>3</Data></Cell>
<Cell Index="3"><Data>B</Data></Cell>
<Cell Index="5"><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>4</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell><Data>B</Data></Cell>
<Cell><Data>C</Data></Cell>
<Cell><Data>D</Data></Cell>
</Row>
<Row>
<Cell><Data>5</Data></Cell>
<Cell><Data>A</Data></Cell>
<Cell Index="4"><Data>C</Data></Cell>
<Cell><Data>D</Data></Cell>
</Row>
</Table>') doc from dual
SELECT x.*
FROM t, xmltable(
'for $j in /Table/Row
return <ROW> {
   for $i at $pos in $j/Cell
   let $x := $j/Cell[position()<=$pos and @Index][last()]/@Index
   let $x2 := if($x) then $x else 1
   let $p := count($j/Cell[@Index=$x]/preceding-sibling::*)+1
   return <DATA pos="{$pos - $p + $x2}">{$i/Data/text()}</DATA>
} </ROW>'
PASSING t.doc
COLUMNS cell1 number      PATH '/ROW/DATA[@pos="1"]',
         cell2 varchar2(1) PATH '/ROW/DATA[@pos="2"]',
         cell3 varchar2(1) PATH '/ROW/DATA[@pos="3"]',
         cell4 varchar2(1) PATH '/ROW/DATA[@pos="4"]',
         cell5 varchar2(1) PATH '/ROW/DATA[@pos="5"]'
) x;Basically, the XQUERY reconstructs each row and gives each cell its true position. We can then access the data with a simple position predicate.
It works well for small documents, but rapidly shows awful performance as the size increases (which is understandable).
So my question : is there a better way to achieve the requirement (or to improve performance)?
Thanks a lot.

what if you do the logic outside of the xquery?

ExtractValue vs. XMLTable Character Entity Decoding

In removing the deprecated extract/extractValue methods from my queries, I have run into an issue with character data being extracted via XMLTable.
Character entity encoded data (e.g. "'" as "'") was decoded by extractValue, but remains encoded by XMLTable. For example:
WITH myXML AS
    SELECT XMLTYPE.createXML('<root desc="Here' || chr(38) || 'apos;s an example"/>') AS x
    FROM dual
SELECT
x,
extractValue(x, '/root/@desc'),
mytab.example,
XMLQuery('/root/@desc' PASSING x RETURNING CONTENT).getStringVal()
FROM
myXML,
XMLTable
    '/root'
    PASSING myXML.x
    COLUMNS
      example VARCHAR2(39) PATH '@desc'
) mytab;returns
<root desc="Here's an example"/>     Here's an example     Here's an example     Here's an example
Wrapping each column in the SELECT clause in dbms_xmlgen.convert() seems like overkill. Am I doing something wrong?
Thanks.

Funny, didn't notice that one before.
It seems it happens only with attributes in transient XMLType instances.
For example, it works if the XML document is store in an XMLType column/table :
SQL> create table tmp_xml of xmltype;
Table created
SQL> set scan off
SQL> insert into tmp_xml values (xmltype('<root desc="Here's an example">R&D</root>'));
1 row inserted
SQL>
SQL> SELECT x.*
2 FROM tmp_xml t
3     , XMLTable('/root'
4        PASSING t.object_value
5        COLUMNS
6          example varchar2(20) PATH '@desc'
7        , content varchar2(30) PATH 'text()'
8       ) x
9 ;
EXAMPLE              CONTENT
Here's an example    R&D
Workaround with a transient XMLType : the fn:data() function
SQL> SELECT x.*
2 FROM XMLTable('/root'
3        PASSING xmltype('<root desc="Here's an example">R&D</root>')
4        COLUMNS
5          example varchar2(20) PATH '@desc'
6        , content varchar2(30) PATH 'text()'
7       ) x
8 ;

4        COLUMNS
5          example varchar2(20) PATH 'data(@desc)'

What is going on with the syntax of XMLTABLE?

Hello! What is that with the syntax XMLTABLE? For example
from tgc_xml tt2, xmltable('/ROWSET/ROW' passing tt2.xml_field) tgc;
That is first I have to declare the table in front of the function call, then, after a comma, call a function with that table. How do I write such functions? If I can't do that in PL/SQL, how did Oracle did it?
[Oracle documentation|http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAHBFGE]
Oracle documentation says:
Whenever a PASSING clause refers to a column of an XMLType table in a query, that table must appear before the XMLTable expression in the query FROM list. This is because the XMLTable expression depends on the XMLType table — a left lateral (correlated) join is needed, to ensure a one-to-many (1:N) relationship between the XMLType table row accessed and the rows generated from it by XMLTable.

Hi,
That is first I have to declare the table in front of the function call, then, after a comma, call a function with that table. How do I write such functions? If I can't do that in PL/SQL, how did Oracle did it?What's so confusing about it? It's a built-in function based on the SQL/XML standards, just like XMLElement, XMLAgg etc.
Conceptually, we can see XMLTable as a pipelined table function, with a syntax of its own.
Something like this, for instance, is not that much different, and it's available to us in (PL/)SQL :
SELECT x.*
FROM my_table t
   , TABLE(
       my_pipefunction(t.col1, t.col2)
     ) x
;

FBI not used in xmlquery

G'day all,
Running the following set-up: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Getting a full table scan on a table with an FBI.
Here is a sample set-up:
create table a (id number, filepath varchar2(256 char));
insert into a values(1,'/dir/subdir/file1.xml');
insert into a values(2,'/dir/subdir/file2.xml');
insert into a values(3,'/dir/subdir/file3.xml');
insert into a values(4,'/dir/subdir/file4.xml');
insert into a values(5,'/dir/subdir/file5.xml');
commit;
create index filepath_substr_fbi on a(substr(filepath,instr(filepath,'/',-1)+1));
create unique index filepath_uidx on a(filepath);So the requirement is to retrieve the ids from the table containing a particular filename. The filenames to retrieve are sourced from an xmltype. The approach I've taken is the following:
select * from a , (XMLTable('for $j in /task/related_files/ora:tokenize(text(),"\|")
where ora:matches($j,"\d+\.xml") return normalize-space($j)'
    PASSING xmltype(
'<task><related_files>File 1|file1.xml|file 2|file2.xml|file 3|file3.xml</related_files></task>'
))) x where substr(a.filepath,instr(a.filepath,'/',-1)+1) = x.column_value.getstringval();which returns the following results:
"ID"     "FILEPATH"     "COLUMN_VALUE"
1     "/dir/subdir/file1.xml"     file1.xml
2     "/dir/subdir/file2.xml"     file2.xml
3     "/dir/subdir/file3.xml"     file3.xmlNow, after running this sample, and doing an explain plan on it, I did notice it used the index!

Indeed, cardinality and selectivity are essential in this case.
Consider the following test case with a 1,000,000-row table, the CBO picks up the index :

This estimation could be refined by using hints : CARDINALITY (not documented), DYNAMIC_SAMPLING, or by using a wrapper function and the extensible optimizer feature.
For example, if you expect at most 10 rows every time :

Problem with xs:integer (I think)

Hi,
Firstly, I'm using Oracle database version 11.2.0.1.0
The overall task is to absorb data from an XML file and create records in a single destination table.
I've studied the excellent thread at Load xml data in Oracle table
and copied and hacked Odie's examples.
I've got something to work, but there's just that one final problem, explained so.
To test out my code, I wrapped the "select" that gets the data from the XML file into a cursor For loop, and inside
the loop body I just use dbms_output so I can see that the values are being processed okay. This works a treat, so my
final task was to abandon the cursor For loop and instead make the select statement the source of data for an Insert
statement. This is where my plans become unstuck.
In order to cater for duplicate rows, I'm using the "at" bit of the "for" loop as so: "for $i at $bibnum in /collection/record".
That bit of data (available through the variable "$bibnum") when printed out via the older dbms_output code did show
a pleasing consecutive sequence of digits. But try and insert this into a plain database table and all I get is nulls. Yuk.
Trying to read around this, I've managed through dubious means to glean that the variable is of type "xs:integer". It seems converting
this to a oracle "number" type is problematic. There is mention on the web page http://docs.oracle.com/cd/E14571_01/doc.1111/e15867/app_xquery_sql_reference.htm
about conversion from "number" to "xs:integer", hence I am presuming that the converse also holds.
But the blooming thing still doesn't work.
Other numbers from the select statement populate into my destination table fine. It's just the xs:integer that's the issue.
I've tried changing the "columns" part of the xmltable call and used "number", "number(8)", "number(8,0)" and other variants. No joy.
I've also tried changing the column type of the target table. Still no joy.
I've tried converting the xs:integer to a xs:decimal, and then use that. Still nothing.
Time to throw myself on the mercy of the forum. Any easy way to convert the xs:integer into a plain string?
If there is no obvious answer, I will throw together a small self-contained piece of example code and come back here.
Any help appreciated; thanks in advance.
Mungo (newbie with xmltables - probably going round the "long" way on this task :-)

That's a funny one, SELECT is working but INSERT is not...
I guess it's an issue with the CBO and XQuery optimization.
If you're always using a variable as your XML source, you can disable it by adding the NO_XML_QUERY_REWRITE hint. It should solve the problem :

How to insert data in the table without join and using mapped rule value

1.Table SOL_K
A B C D – Columns Name
C D A B –Coulmns Values Defined (Rule --- Defined)
2.SECOND table SIC_K
SIC_ K
A B C D
Kamal Micky NULL MANOJ
3 Table SIC_Mapping
Same Columns A B C D based On Table SOL_K defined rule
I want to insert values(from table SIC K) into table SICMapping Table with the help of first table(SOL_K)(mapped rule)
Required Result SIC_Mapping Table
The output will be come like this.
A B C D — Columns Name
NULL MANOJ Kamal Micky ---- Came based on defined Mapping Rule

What's your database version?
That's a funny requirement.
How about :
select case sol.a
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as a
     , case sol.b
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as b
     , case sol.c
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as c
     , case sol.d

          when 'C' then sic.c
          when 'D' then sic.d
       end as d
from sol_k sol, sic_k sic
;XQuery can do the trick too :
SQL> SELECT *

Loading data into XMLType column using dbms_xmlsave.insertxml get ORA-29532

The following simple test case succeeded in 9.2.0.1 but failed in 9.2.0.2.
CREATE OR REPLACE procedure InsertXML(xmlDoc IN VARCHAR2, tableName IN VARCHAR2) is
insCtx DBMS_XMLSave.ctxType;
rows number;
begin
insCtx := DBMS_XMLSave.newContext(tableName); -- get the context handle
rows := DBMS_XMLSave.insertXML(insCtx,xmlDoc); -- this inserts the document
dbms_output.put_line(to_char(rows) || ' rows inserted');
DBMS_XMLSave.closeContext(insCtx); -- this closes the handle
end;
CREATE TABLE XMLtable
(column1 xmltype)
exec insertxml('<?xml version = "1.0"?><ROWSET><ROW><COLUMN1><TEST>HELLO</TEST></COLUMN1></ROW></ROWSET>', 'XMLTABLE');

Hi,
For your XML file I think you just need to enclose XML elemnts in ROWSET AND ROW TAGS - so xml should look like :
<ROWSET>
<ROW>
<DEPT>
</DEPT>
and just pass it as CLOB to dbms_xmlsave.insertXML proc.
I hope it should work.
I am also trying to insert XML file but with a bit complex structure having multiple nested elements.
I am not sure how to transform the external XML file to wrap it in ROWSET/ROW using XSLT. It's mandatory to use ROWSET/ROW tags to be able to insert in oracle tables. I am facing this problem right now. I am using object views to accomplish the purpose but still needs to figure out the way to apply stylesheet to incoming XML file.
If you come to know of any way, pls do let me know also.
Thanks

Read XML file into databased using stored procedure

Parsing a string in a given order

Hi All,
I want to parse a string and rank it in a given order.
Eg : i have a string as 'A | B | C | D'. I would like to parse this string and give a rank in order.
It should appear as below.
Parsed string order
D 1
C 2
B 3
A 4
Any help is greatly appreciated..

A database version would help us providing you with a relevant solution.
Starting with 10g, you can do :
SQL> var my_str varchar2(30)
SQL> exec :my_str := 'A|B|C|D'
PL/SQL procedure successfully completed
SQL> select item
2       , row_number() over(order by item desc) as rank
3 from (
4    select regexp_substr(:my_str,'[^|]+',1,level) as item
5    from dual
6    connect by level <= length(regexp_replace(:my_str,'[^|]+')) + 1
7 );
ITEM                    RANK
D                          1
C                          2
B                          3
A                          4
In 11.2 :
SQL> select *
2 from xmltable(
3       'for $i in ora:tokenize($str,"\|") order by $i descending return $i'
4       passing 'A|B|C|D' as "str"
5       columns item varchar2(10) path '.'
6             , rank for ordinality
7       )
8 ;
ITEM             RANK
D                   1
C                   2
B                   3
A                   4

Hi David, please do visit the XML DB forum. There is an Oracle guy named Mark Drake and he is very good at this stuff. To your questions, yes, Oracle XML DB can handle any type of XML no matter how many levels you have. Check out the XMLTable function in the Oracle XML user's guide and it is pretty powerful. The trick is that it is hard if not impossible to combine singletons and multiples, because multiples require its own handling. I have to deal with this a lot. In some cases, I can use two xmltables, one for the multiples and one for the singlton, repeating the singleton for each of the multiples in one table. In other cases I just do two steps: get the multiples and singltons separately. You will find that using the global temporary table for this type of xml processing comes handy. At our place, some people use BizTalk to "map, orchestrate, factor and re-factor" xml messages from a partner, but I use Oracle XML DB. I have completed all available xml messages (more than 20) in just a short time, but it took the BizTalk consultants almost 5 months to finish one simple xml message! When I say Oracle does a beautiful job, they are not happy so they tell me that I should have been an Oracle salesman.
