Selective extraction from an xmltype variable

I have a fragment of XML -
<Unit name="MAIN UNIT">
<Ops event_type="U1" cause_code="7050" begin_time="2003-06-13T09:38:00">Broken restoring cable</Ops>
<Ops event_type="GE" cause_code="0001" begin_time="2003-06-03T07:07:03"/>
<Generation begin_time="2003-06-13T00:00:00" end_time="2003-06-13T23:59:59" mwh_produced="229.00" mwh_consumed="0.00"/>
</Unit>
I am trying to extract just the text of an "Ops" fragment. In the above case, the first would be "Broken restoring cable" and the second would be NULL. Using
v_belement.extract('/Ops').getStringVal()
inside of a loop through the array gives me the entire fragment. How can I get just the text?

Bill,
Try extractValue instead of extract.

Select values from table%ROWTYPE variable into a cursor

I have a stored procedure which has an OUT parameter of table1%ROWTYPE.
In future we might have to add more OUT parameters of table2%ROWTYPE etc. But at any point of time only one will have values.
So instead of having table%ROWTYPE as OUT parameter, can I send these single row ( with variable values) in a cursor, so that declaration part atleast will not change.
Is it possible to select values from table%ROWTYPE variable into a cursor.
cursorOUT IS
SELECT * FROM varREC;
where varREC is table.ROWTYPE variable.
Or which is the better solution in this situation.
Thanks.

*SELECT: How to select value from cube into variable?

Hi,
I have an application that need lots of complex calculations. Currently I am facing problem in retrieving a value from BPC application/database (BW cube) into a script logic local variable. Let's say the application has these following dimensions
1. FYPD ( fiscal yr period. 200901, 200902 etc)
2. REGION ( A, B , C , D etc)
3. PRODUCT(Product ID)
4. VERSION ( ACTUAL, FORECAST etc)
5. AMOUNT (Sales Amount, signed data )
Now I need to extract the sales amount into a local valriable where REGION = "A" and PRODUCT = "SMK-1234" and FYPD = "200905" and VERSION = "ACTUAL"
What's should be the equivalent SELECT command? I tried but could not figure out. Any help?
Regards
DipM

Hi DipM,
There isn't really a concept of local variables for values in script logic. Instead, you'll want to use *WHEN, *LOOKUP, or MDX statements.
For example, this will copy the value you mention into the PLAN version:
*WHEN REGION
*IS A
*WHEN PRODUCT
*IS SMK-1234
*WHEN FYPD
*IS 200905
*WHEN VERSION
*IS ACTUAL
*REC(FACTOR=1,VERSION=PLAN)
*ENDWHEN
*ENDWHEN
*ENDWHEN
*ENDWHEN
See *WHEN ([link|http://help.sap.com/saphelp_bpc70sp02/helpdata/en/36/339907938943ad95d8e6ba37b0d3cd/frameset.htm]) and *REC ([link|http://help.sap.com/saphelp_bpc70sp02/helpdata/en/25/8d51050c43496887ddff88f13e5f1a/frameset.htm]) documentation for more.
As mentioned, you can also use *LOOKUP or MDX statements to look up values and drive calculations in *REC(EXPRESSION=....) statements. This functionality is outlined in the SP02 documentation addendum ([link|http://service.sap.com/~form/sapnet?_SHORTKEY=00200797470000088146&_SCENARIO=01100035870000000202&]).
In the MS Version of BPC, there is a concept of local MDX variables that work with the specialized *GO script logic statement. This statement is not available in the Netweaver version.

Best tool to extract xml when xmltype structure may vary

Hi
I was wondering if there is a better option to select data from an xmltype column when the data may be stored in different xml structures? I was using xmlsequence but this would lead to too many unions since the data is stored differently. What are the other alternatives that I may use?

I have reviewed the contents in the FAQ (great start, thanks!). I am still a little confused now as to how I will parse out the data for inserts into a table. I will ALWAYS insert the document's contents in their entirety. Here's what I've tried. f I want to extract the file (delivered attribute), I can do this:
select extract(x.file_content,'/hdf5/file/@delivered')
from xml_stage x;
This returns ALL the "file delivered" attributes for the whole document - but I'm not sure how to separate them into individual logical records. My output looks like (only a snippet here....):
20100812042714201008120428152010081206015620100812060156201008120601562010081206015620100812060757....
Looking in the XML file - the value for the first delivered attribute is 20100812042714, the second record would be 20100812042815, etc.
What am I missing?

Use variables in a SELECT INTO FROM command

Hi,
How do I use variables within a select into from command? I want to loop through SYS.DBA_TABLES using a cursor and count the number of rows in a
selection of tables an then insert into a cardinality table.
The count of rows will be stored in a variable called CNT, that bit is easy however I need a variable in the FROM clause because that
value changes with every iteration of the cursor.
e.g.
CNT := 0;
TN := "MyTable";
select count(*) into CNT FROM TN;
insert into cardinality (table_name, row_count) values (TN, CNT);
This is Oracle 9i and I need the row counts in a separate table as they are shipped over to a different environment for analysis purposes.
Any ideas?
Regards
Dave

Hi,
Thanks for the info, unfortunately I can get neither example to work on this 9i system, could well be pilot error as I only ever get
to do any Oracle about once per year. In the first query I have tried both "user_tables" and SYS.DBA_TABLES, same result.

vstr1 := vstr || i.table_name;
EXECUTE IMMEDIATE vstr1

dbms_output.put_line(i.table_name || ':' || row_count);
END LOOP;
END;
This one complains about the execute immediate line.

ORA-00600 occurs on an extract from a large xmlType column

When running the extract() function where search criteria has been specified (for an existing node), I receive the following error:
ORA-00600: internal error code, arguments: [qmxdMatchingChildren:overflow-1],[], [], [], [], [], [], []
However, if I remove the search criteria, the fragment returns no error.
Both queries have been working successfully on smaller documents.
Example with criteria:
SELECT extract(tab.xml_text,'//item[@val="2.1.2.2"]') ITEM
FROM CUR.ITEMS tab
WHERE item_id =271;
Example without criteria:
SELECT extract(tab.xml_text,'//item') ITEM
FROM CUR.ITEMS tab
WHERE item_id =271;
I'm estimating that the document inside the xmltype column is 4MB.

If retval contains the whole response including envelope, then obviously it doesn't start at "TICKETCreateRespMsg". You have to use the full path, or a descendant axis, but the former is preferred.
Be aware of namespaces too, that's a common gotcha with XML.

Select extract(month from sysdate)+6 = returns 13 and not 1(jan)

Hi
I am using the following query to get the month 6 months from now.
select extract(month from sysdate)+6
from dualHow can I say that the month should be 6 months from todays month? It worked all these days because this month + 6 was always a valid month. Now it returns 13.

When I run the following, I get '1'. I am expecting '01'. What am I doing wrong here?
SELECT substr(lpad(to_number(to_char(ADD_MONTHS(SYSDATE, 6),'MM')),2),1,2) FROM DUAL;
I need number - so using to_number. I need to extract the month, so using to_char. If someone could help me get 2 digits for the month and simplify the query if possible - would be great.
The table has month and date stored as number (bad idea I know but thats how it is). Now for January 31, it is stored as 131. For 15 Feb it is 215. What I need is give me records where the month is 6 months from now. Something like:
to_number(substr(lpad(tbl1.monthdt, 4, '0'), 1, 2)) in
substr(lpad(to_number(to_char(ADD_MONTHS(SYSDATE, 6),'MM')),2),1,2)Message was edited by:

Extract from XML

Hi to everyone,
I'm new in Oracle and I've - maybe trivial - a problem in a select. (I'm using Oracle 10g Express Edition).
I've a DB with a field CLOB: mytab.xml
This column have an XML like this:
<?xml version="1.0" encoding="iso-8859-1"?>
<info>
<id> 954 </id>
<idboss> 954 </isboss>
<name> Fausto </name>
<sorname> Anonimo </sorname>
<phone> 040000000 </phone>
<fax> 040000001 </fax>
</info>
I'm trying to do a 'simple' select to get, for example, the value of 'fax' tag. But I've a bit of problem and I'm not able to understand my error. For example:
select extract(xml, '//fax').getStringVal() from mytab;
ORA-00932: inconsistent datatypes: expected - got
select extract(xmltype(xml), '//fax').getStringVal() from mytab;
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SYS.XMLTYPE", line 254
I've tryed also with 'extractvalue', but I've the same problems.
where I'm wrong to do this?

Select Extract(Xmltype(Xml),'/anagrafica/fax/text()').Getstringval() As Xml_Result From Anagrafica;
XML_Result

So it seems that there is no error in the query itself.
The error related to numeric or value error might be a bit of the clue: Please note that the return value has spaces on both sides. If you try to assign it to numeric variable, you might get such error.
Not sure if it helped.

Is it possible to concatenate XMLType variable

I'm using XQuery to query relational table and store the result into an xmltype variable as shown below:
SELECT XMLQuery('<Data>
{for $c in ora:view("TABLEA")
       let $id := $c/ROW/ID/text(), $code := $c/ROW/CODE/text(),
           return
       <result>
         <type>I</type>
         <id>{$id}</id>
<code>{$code}</code>
</result> </Data>' RETURNING CONTENT)
INTO V_Delete FROM dual;
Similarly, I query other tables and store the result in xmltype variable. My requirement is to generate one xml file out of it. This would mean that I would need to consolidate the values stored in different xmltype variables. Is it possible to concatenate the xmltype varialbe? If so, how? If not, what is the alternative? I tried converting it to string, but then the 4000 limit caused an error.

Hi, as I said I have not done that myself. But you can read chapter 4 of the XDB Developer's Guide of the Oraclce docs and I think it may help. The examples there show that those functions are used to update a table. It has this example,
UPDATE purchaseorder
SET OBJECT_VALUE =
appendChildXML(OBJECT_VALUE,
'/PurchaseOrder/Actions/Action[1]',
XMLType('<Date>2002-11-04</Date>'))
WHERE existsNode(OBJECT_VALUE,
'/PurchaseOrder[Reference="AMCEWEN-20021009123336171PDT"]')
= 1;
SELECT extract(OBJECT_VALUE, '/PurchaseOrder/Actions/Action[1]')
FROM purchaseorder
WHERE existsNode(OBJECT_VALUE,
'/PurchaseOrder[Reference="AMCEWEN-20021009123336171PDT"]')
= 1;
That was why I thought using a global temp table would help in this kind of operation. What I did was using select xmlelement(namespace declarations) from dual, then using a nested (select xmlelement() ) inside the from dual part. I have to select from many different tables to create one xml and it works for me, but I did not try the other ways. If you just need to attach the prolog and namespace stuff, you can store them in a clob or varchar2 var and convert the xml to clob and that simply concantenate them, and then convert the clob back to xml. In 10g there is also the new XMLProlog (I forgot the exact name at this moment) function. Check that out and see if it will work for you.

Select data from an XML Column in a Relational Table

Hi guys,
I read a lot of documentation from Oracle how to select xml nodes from an XML Table. The following statement works perfectly for an XML table.
select extract(OBJECT_VALUE, '/loop/loop_data/description') "DESCRIPTION"
from loop_table
where xmlexists('/loop/loop_data[type_code="212"]' PASSING OBJECT_VALUE);
BUT: how to select xml nodes (data) from a relational table with an XML column???
I'm interested in the xml data.
Thanks!
