The problem is this part:
strasse2 VARCHAR2 (2000) PATH ' / gast/@strasse2'
From the PATH expression a slash device 'find the gast node at the root of the context item', but here the context item is the 'meldeblatt' node, so the path expression target no node.
The other problem is that step 'gast' should be in the main XQuery expression, if you want to iterate through the sequence of nodes 'gast '.
This should be what you want:
...

' / meldeblatt/gast.
PASSAGE gastinfo

reload the page when SQL query returns a value
Hello world
the title of this discussion may seem strange, but I'll try to explain why I need this:
A user has the ability to connect on my APEX application. There are several tabs in my application that are visible only if a certain SQL statement returns a value which is not the case by default. The user has also the ability to download a file that is transferred to an external system that analyzes the file and writes the data in the database. During this writing process - which may take several minutes - conditions for some of the tabs to show the will becomes real (-> the query will return a value). When the user refreshes the page manually, the tabs will be displayed. However, I want the tabs will appear automatically when the condition is met.
Is it possible to refresh the page as soon as the query returns a value? It is perhaps possible to check it on the client side and trigger a refresh of the page when the condition is met. It would be even better if only the tabset has been updated, but refreshing the full page is fine as well.
Thank you!
Here is an overview of how it can be done
This is possible thanks to a dynamic action being performed on a timer.
View default tabs and dynamic action hide them on loading the page if they are not to be considered
Create a dynamic action that will execute your query every 5 seconds or more
If the query returns data, you can use the dynamic action to show your tabs using javascript

I am using the following query - where the get_combined_Code function returns the above XML code
This query returns no records.select x.* from ( select facsite_pkg.get_combined_code('county') xml from dual) t, xmltable(xmlnamespaces('a' as "a"), '//a:CombinedCodeEntity' passing t.xml.extract('//a:CombinedCodeEntity', 'xmlns:a="http://schemas.datacontract.org/2004/07/WA.Ecy.ADS.CombinedCode.Service.DataAccess" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"') columns code_id varchar2(10) path 'a:CombinedCodeValue', code_description varchar2(100) path 'a:CombinedCodeDescription') x
I first tried this without the namespace clause, but this failed with the error: ORA-19228: XPST0008 - undeclared identifier: 'a' local-name of the prefix ' a: CombinedCodeEntity'
I also tried to make the namespace clause
but the end result is the same.xmlnamespaces('urn:WA.Ecy.ADS.CombinedCode.Services' as "a")
Any thoughts on where things have gone wrong?

XML query returns empty when tags no data
Hi all
I have a problem that I can't solve.
I have the following query:
The query returns the XML code in the desired structure.select xmlelement ( "users", xmlagg ( xmlelement ( "user", xmlelement ( "username", e.pin ), xmlagg ( xmlelement ( "details", xmlforest ( e.password as "password" ,e.first_name as "forename" ,e.surname as "surname" ,'0' as "retired" ,e.email_address as "email" ,e.telephone_number as "phone" ,'No External Ref' as "externalRef" ,add_months(sysdate,+60) as "expiryDate" ) ) ) ) ) ) xml_out from aqaost_examiners e group by e.pin;
But the problem I have is that when there is no data found by the query, I always get a single row returned by the following: < user > < / users >
I tried so many things to try to have the query return nothing if there is no data available, but I can't do without something else goes wrong (to mess up the XML structure, etc.).
Please is - can anyone help or point me in the right direction?
I thank very you much in advance!
RobinHello
Peter,
This is the GROUP that does this.
Actually no, the GROUP BY refers to the deepest XMLAgg and is required if e.pin is not unique.
Let it out, and you also seem to have of many XMLAGG (?)
That's assuming that e.pin is unique within the table (which is probably a fair assumption in this case).
In fact, the behavior comes from the XMLAgg in the foreground:
SQL> select xmlelement("users", 2 xmlagg( 3 xmlelement("user", 4 xmlelement("username", e.empno) 5 , xmlelement("details", 6 xmlforest( 7 e.ename as "name" 8 , e.job as "job" 9 ) 10 ) 11 ) 12 ) 13 ) xml_out 14 from scott.emp e 15 where 1 = 0 16 ; XML_OUT -------------------------------------As with other global functions (such as SUM or AVG) adding a GROUP OF 'something' solves the problem:
SQL> select xmlelement("users", 2 xmlagg( 3 xmlelement("user", 4 xmlelement("username", e.empno) 5 , xmlelement("details", 6 xmlforest( 7 e.ename as "name" 8 , e.job as "job" 9 ) 10 ) 11 ) 12 ) 13 ) xml_out 14 from scott.emp e 15 where 1 = 0 16 group by null 17 ; no rows selectedRobin,
So the more intimate XMLAgg is really necessary, you can use a subquery:select xmlelement("users", v.users) from ( select xmlagg( xmlelement("user", xmlelement("username", e.empno) , xmlagg( xmlelement("details", xmlforest( e.ename as "name" , e.job as "job" ) ) ) ) ) as users from scott.emp e group by e.empno ) v where v.users is not null ; -

UNDERSTANDING
---------------------------
As my Xpath only points until the node - ParentPicklistValue and not the child nodes under it. That's why, when I try to interview the child nodes - / ParentPicklistValue/ListOfPicklistValue/PicklistValue/Code, I get the error mentioned above.

Can someone help me to receive the values of the mother and child values based on xml and query above.Hello
It's a classic ;)
You need a second XMLSequence who shreds the collection of PicklistValue in relational lines:
select extractvalue(value(sr2), '/PicklistValue/Code', 'xmlns="urn:/crmondemand/xml/picklist"') AS Display , extractvalue(value(sr2), '/PicklistValue/DisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS Return , extractvalue(value(sr1), '/ParentPicklistValue/ParentDisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_display , extractvalue(value(sr1), '/ParentPicklistValue/ParentCode', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_return from table( xmlsequence( extract( WEB_SERVICE( ... ) , '/soap:Envelope/soap:Body/ns:PicklistWS_GetPicklistValues_Output/ListOfParentPicklistValue/ParentPicklistValue' , 'xmlns="urn:/crmondemand/xml/picklist" xmlns:ns="urn:crmondemand/ws/picklist/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' ) ) ) sr1 , table( xmlsequence( extract( value(sr1) , '/ParentPicklistValue/ListOfPicklistValue/PicklistValue' , 'xmlns="urn:/crmondemand/xml/picklist"' ) ) ) sr2 ;What is your version of the database BTW?
10.2 and upward, you can use the XMLTable. -
Query must return the values null
Hi once again, everything
The query below should return zero values for the date, but instead it brings back each transaction in the table, any ideas why?
SELECT CID.transaction_id, MMT.ITEM_ORD PART_NUMBER, CID.DESCRIPTION, CID.TRANSACTION_TYPE_NAME, CID.LINE_TYPE_NAME, CID.SUBINVENTORY_CODE, MMT.TRANSACTION_QUANTITY, CID.BASE_TRANSACTION_VALUE TRANSACTION_VALUE, GLC.SEGMENT1, GLC.SEGMENT2, GLC.SEGMENT3, GLC.SEGMENT4, GLC.SEGMENT6, TO_CHAR (MMT.TRANSACTION_DATE, 'DD-MON-YY HH24:MI') transaction_date_and_time, TRUNC (MMT.TRANSACTION_DATE) transaction_date FROM CST_INV_DISTRIBUTION_DAV_V CID, MTL_MATERIAL_TXNS_VAL_V MMT, GL_CODE_COMBINATIONS GLC WHERE CID.TRANSACTION_ID = MMT.TRANSACTION_ID AND CID.REFERENCE_ACCOUNT = GLC .CODE_COMBINATION_ID; AND MMT.TRANSACTION_DATE = '26-AUG-11 22:00'Yes. It's true. You must use TO_DATE to convert a string to a date and you must use TO_CHAR to convert a date into a string.

DICOM metadata - extractvalue returns the value of a single node
Hello
I have difficulties in getting the value of the objects with repeated elements. Specifically, I need to get the value of spacing of pixels in the following excerpt from xml.
Normally, I use the following query to get the value of spacing of pixels:<DICOM_OBJECT> .. <DECIMAL_STRING tag="00181063" definer="DICOM" name="Frame Time" offset="900" length="2">0.0</DECIMAL_STRING> <CODE_STRING tag="0018106A" definer="DICOM" name="Synchronization Trigger" offset="910" length="10">NO TRIGGER</CODE_STRING> .. <DECIMAL_STRING tag="00280030" definer="DICOM" name="Pixel Spacing" offset="1660" length="22">0.003562</DECIMAL_STRING> <DECIMAL_STRING tag="00280030" definer="DICOM" name="Pixel Spacing" offset="1660" length="22">0.003562</DECIMAL_STRING> <UNSIGNED_SHORT tag="00280100" definer="DICOM" name="Bits Allocated" offset="1690" length="2">8</UNSIGNED_SHORT> <UNSIGNED_SHORT tag="00280101" definer="DICOM" name="Bits Stored" offset="1700" length="2">8</UNSIGNED_SHORT> .. </DICOM_OBJECT>
It works, but not when there are two elements. Then I get the error: "ORA-19025: EXTRACTVALUE returns the value of a single node.select EXTRACTVALUE(t.dicom.metadata ,'/DICOM_OBJECT/*[@name="Pixel Spacing"]' ,'xmlns=http://xmlns.oracle.com/ord/dicom/metadata_1_0') scale_factor from my_dicom_object t
All I really need is to get the value of the first node with the name of "spacing of pixels. Despite the many examples available to do with traditional xml paths, I was unable to find an example that makes using XPATH search strings rather than direct tag structure.
Can someone give an example?
Thank you!

Function return undefined values
My function returns undefined values. It seems that the return of the function statement is executed before the database is queried and values are assigned to variables. If I do an alert within the loop for () I get the correct values from the database, but these values are not affected before excecuting the return statement function. How can I do this differently?
function getColumnNames(table){ var rs1, rs2, rs3, rs4, rs5; db.transaction(function (tx) { tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){ var size = results.rows.length, i; var item; for (i = 0; i < size; i++){ item = results.rows.item(i); rs1 = item.col1; rs2 = item.col2; rs3 = item.col3; rs4 = item.col4; rs5 = item.col5; alert(rs1); //correct value is returned here } }); }); return [rs1, rs2, rs3, rs4, rs5]; }Hey Fabian,.
You are quite correct that the return statement is executed before the database returns the results. There are ongoing asynchronous calls. You can set breakpoints in JavaScript code to see what is happening. You can correct the problem by using function callbacks. I edited your code below to use the callback functions - there might be a few typos, but the general approach should be wooded.
function getColumnNames(table, callback){ var rs1, rs2, rs3, rs4, rs5; db.transaction(function (tx) { tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){ var size = results.rows.length, i; var item; for (i = 0; i < size; i++){ item = results.rows.item(i); rs1 = item.col1; rs2 = item.col2; rs3 = item.col3; rs4 = item.col4; rs5 = item.col5; alert(rs5); //correct values are being returned callback([rs1, rs2, rs3, rs4, rs5]); } }); }); } // example of how to call getColumnNames with callback getColumnNames('importantTable', function (result) { console.log(result); }); // alternative version function onCallback(result) { console.log(result); } getColumnNames('importantTable', onCallback);I hope this helps.
See you soon,.

Add a string when the query returns all records
DB version: 11.2
create table t (empname varchar2 (25), salary number, varchar2 (20) months, number of over_time);
insert into values t ('JOHN', 2000, "NOVEMBER2014", 0);
insert into values t ('KATE', 2000, "NOVEMBER2014", 300);
insert into values t ('HANS', 5000, "NOVEMBER2014", 100);
insert into values t ("KRISHNA", 2500, "NOVEMBER2014", 0);
insert into values t ("SIEW", 3000, "NOVEMBER2014", 0);
commit;
SQL > select * from t;
EMPNAME MONTHS SALARY OVER_TIME
------------------------- ---------- -------------------- ----------
JOHN 2000 NOVEMBER2014 0
KATE 2000 NOVEMBER2014 300
HANS 5000 NOVEMBER2014 100
KRISHNA 2500 NOVEMBER2014 0
SIEW 3000 NOVEMBER2014 0
SQL > select * from t where MONTH = 'NOVEMBER2014' and OVER_TIME! = 0 ;
EMPNAME MONTHS SALARY OVER_TIME
------------------------- ---------- -------------------- ----------
KATE 2000 NOVEMBER2014 300
HANS 5000 NOVEMBER2014 100
What I need is:
If the query above returns at least one record, it should display the line ' Yes. We have one or more employees who worked overtime in November2014'
before the documents are printed
Thus, the expected production is
Yes. We have one or more employees who worked overtime at the November2014
EMPNAME MONTHS SALARY OVER_TIME
------------------------- ---------- -------------------- ----------
KATE 2000 NOVEMBER2014 300
HANS 5000 NOVEMBER2014 100
If the query returns no records then usual 'no rows selected' isn't enough
Lothar G.f. says:
In fact, sql * more is no good tool for use considered.
Really? It may be a good reporting tool if you learn to use it as such...
for example
SQL > ttitle left 'Yes. We have one or more employees who worked overtime in November2014.
SQL > select * from emp where empno = 1234;no selected line
SQL > select * from emp where empno = 7788;
Yes. We have one or more employees who worked overtime at the November2014
EMPNO, ENAME, JOB HIREDATE DEPTNO COMM SAL MGR
---------- ---------- --------- ---------- -------------------- ---------- ---------- ----------
7788, SCOTT, ANALYST, 7566 19 APRIL 1987 00:00:00 3000 20This is just a basic example. It is possible to get SQL * more to ask for the required criteria and that the title could adjust according to this criterion, as well as the query building on it also.
However, the OP did not specify SQL * as the reporting tool, so there is little interest providing a complete solution which, until they specify what user interface that they are actually using.

What subprogramme should we prefer to return multiple values with OUT parameter?
Hello
I worked on the procedures and functions, and aware of their differences. Today I have an interview question that - suppose I don't have return multiple values through a subroutine and I want nor run any what DML within this subprogramme and I want to use this subprogramme in the SQL query. What subprogramme I would prefer - "Operating Mode" or "Function" and why?
In my view, both can be used in this case, but want to see your views and opinions.
Kind regards
Sachin jerbi
In terms of software engineering, if you claim something that you expect to "return" something (a value or values) then you use a function. If you call something to "do" something, and then you use a procedure.
THE settings are not good practices in many cases and should not strictly considered "return" of values. Instead, they are assigned values in the code and generally act as pointers to the original variable/structure that was passed as a parameter (the actual internals of Oracle don't quite do it, but in principle this is what they do).
A return value (or structure) of a function is basically push in the battery to the point that the RETURN statement is issued, and then the code calling the stack appears to assign it to a variable or placeholder, it should go in.
If it seems a little difference between procedures and functions to some people, it is recommended to use functions for obtaining values and procedures to do things, in most cases. It is not just "syntactic sugar", as mentioned above.

Hello
You want to use the filter to add an XML node.
Create a JavaScript filter, first to do something like this:
function invoke (msg)
{
now = new Date();
Msg.put (elements "UTCTime", now.toUTCString ());
Returns true;
}
In Add an XML node to the node content add:

A row of Sub query returns more than 1 row!
I'm trying to update the values in one table from another table and get the error: void line query returns More Than 1 row.
I want to PRV_NAME B chart updated in the table A PRV_NAME where A.PRVID = B.PRVID where B.PRV_TYPE = M"
The two paintings were all unique PRVID, however, table B has PRVID that have the same name. So the data in table B can look like this:
PRVID PRV_NAME
1234 PHOENIX MED
1235 MED BAG
1236 MED BAG
1237 OVERLAND
etc...
So, as you can see are the unique PRVID, but not the PRV_NAME. Is this the reason why I get this error?
I do not build the tables and have no control over what is put in them. If this is the reason for the error, is there a way to fix this?
For reference, here's the request. Maybe there's something wrong with that?
