Tree query using XML SQL

Hi,
Any ideas or code samples of how we could use the XML SQL Utility
to do a tree structure, like the following:
<GROUP id="grp1">
<ITEM> item 1 </ITEM>
<ITEM> item 2 </ITEM>
<GROUP id="grp2">
<ITEM> item 3 </ITEM>
<ITEM> item 4 </ITEM>
</GROUP>
<ITEM> item 5 </ITEM>
</GROUP>
Thanks,
Cyril.

Hi Mark,
To a certain extent one can modify the xml generated by
manipulating the query and by using some of the tag name
customizations which the XSU allows. Unfortunately, what you
want to create will take more than that; you will have to use
XSLT - xml transformation language, part of XSL. You will find
and XSL processor packaged with the oracle xml parser v2 (see
oraxsl). You can find more info on XSLT at www.w3c.org

Generating multi-level XML in Oracle 8i using XML-SQL utility

Oracle 8i has a limitation when it comes to the object types. Only one-level nesting of collection is allowed. Oracle 9i apparently removes this limitation.
I am trying to generate XML for a hierarchical (conceptually) structure. To do that I am using XML-SQL utility (XSU) running agains an object view build on top of the relational data. The problem is the limit to onelevels of colelction nesting. Oracle 8i gives you a way to create a view with more levels of nesting by using references (REF). The problem is that when XSU runs agains a view with the references, it inserts the references into the XML document (instead of dereferencing them).
Is there a way to generate XML with Oracle 8i with more than two levels of collection nesting?
Thank you.
Michael

Crosstab query using pure SQL only

Hi all,
Found a lot of threads on crosstab, but none seems to address what I need. I need to perform crosstab query using pure SQL only & the number of columns are dynamic. From a query, I obtained the below table:
Name Date Amount
Alex 2005-06-10 1000
Alex 2005-06-20 1000
Alex 2005-07-10 1000
Alex 2005-07-20 1000
Alex 2005-08-10 1000
Alex 2005-08-20 1000
John 2005-06-10 2000
John 2005-06-20 2000
John 2005-07-10 2000
John 2005-07-20 2000
John 2005-08-10 2000
John 2005-08-20 2000
And I need to transform it into:
Name 06-2005 07-2005 08-2005
Alex 2000 2000 2000
John 4000 4000 4000
Reason for the columns being dynamic is because they'll be a limit on the date ranges to select the data from. I'd have a lower & upper bound date say June-2005 to August-2005, which explains how I got the data from the above table.
Please advise.
Thanks!

Hi,
I couldn't resist the intellectual challenge of a pure SQL solution for a pivot table with a dynamic number of columns. As Laurent pointed out, a SQL query can only have a fixed number of columns. You can fake a dynamic number of columns, though, by selecting a single column containing data at fixed positions.
 
 
If it were me, I'd use a PL/SQL solution, but if you must have a pure SQL solution, here is an admittedly gruesome one. It shows the sum of all EMP salaries per department over a date range defined by start and end date parameters (which I've hardcoded for simplicity). Perhaps some of the techniques demonstrated may help you in your situation.

1.2 JVM crashes using XML SQL Utility 1.1.10 (NT 8.1.5)

I am trying to use the XML SQL Utility for Java (Oracle 8.1.5) to obtain a DTD or XML schema for tables in our database.
I have installed the XSU111.ZIP archive,
set the CLASSPATH and stuff, loaded the JAR
files (xmlparserv2.jar, oraclexmlsql.jar)
processed the xmlgenpkg.sql script (following the installation instructions)
When I execute the samples in Java, the JVM (JDK 1.2.2) crashes in javai.dll.
The same error occurs when I run java OracleXML getXML ....
The installation file (env.bat) lists the JDBC driver ZIP as CLASSES12.ZIP, which is of course, not available for 8.1.5, which is what the download instructions indicated is appropriate for XSU 1.1.1.
Any ideas? Do I need to upgrade to 8.1.6?
Can I patch the JDBC with classes12.ZIP.
By the way, when I execute the commands in PL/SQL using xmlgen package, everything is fine.
Regards and Much thanks

Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin

Optimizing an SQL Query using Oracle SQL Developer

Hi ,
Currently i am using Oracle SQL Developer as my Database IDE .
Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
For example assume i am having a query as :
Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
Please share your ideas , thanks in advance .

1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.

Query used by SQL Server Management Pack for monitoring database backups

I use SCOM 2012 R2 and the SQL Server Management Pack to monitor SQL Server database backups. I believe I am getting false positives. SCOM reports database are not backuped, while in fact they are. So I need to troubleshoot this. I suspect SCOM is querying
the backup history in the msdb database. I want to know which query SCOM uses.
I have tried looking in the monitor's definition but I suspect the query is embedded in the management pack files which are binary. I have also tried running a trace using the SQL Server Profiler on my test environment and overriding the interval to 60 seconds,
but I don't see a relevant query being executed. I also don't see the alert reappear so I suspect SCOM does not honor the interval in a way I would expect.
What query, or other method, does SCOM use to check database backups?
Thanks in advance.

Thank you both Ivan and Michael,
I only saw your messages by email and didn't see your screen shot before I extracted the query myself. In my own queries I calculate the backup age in hours instead of days because of daily full backups. Perhaps It will be a good idea to create my own monitors
from scratch like I used to do with Nagios.
I will study the vbscripts and might create my own version which allows the query to be entered as an parameter and move all code to a .Net class which can be called from vbscript as an COM object. This way I hope to reduce the vbscript code to an minimum
while keeping the flexibility of the SCOM Operations Console and the robustness of .Net. I suspect I want to make more non standard monitors in the future.

Arjen

Parameter passing to custom SQL query using PL/SQL FUNCTION

Hi
In order to pass a parameter to the query in custom folder of a business area I created a function and mapped it to the Custome query using Discoverer Desktop. There is no error in mapping as the system does not throw any error. When I am inputting the Parameter for the input values everytime the query doesnot return any rows.
Can anybody help in this regard

Hi,
I need to take the request Id as input from the user and then fetch only the data pertaining to that requet Id. As a lot of complex joins are involved I need to pass request id as parameter to the custome folder.
The package i greated:
CREATE OR REPLACE PACKAGE SETPARAM
AS
param1 varchar2(25);
param2 varchar2(25);
FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER ;
FUNCTION GET_PARAM1 RETURN varchar2;
END SETPARAM;
CREATE OR REPLACE PACKAGE BODY SETPARAM AS
FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER IS
BEGIN
fnd_client_info.set_org_context('138');
param1 := p1;
dbms_output.put_line(param1);
RETURN 1;
END;
FUNCTION GET_PARAM1 RETURN varchar2 AS
BEGIN
RETURN param1;
END;
END SETPARAM;
I registered the set_param1 function as a pl/sql function in discoverer admin.
This function is called on the condition associated with the parameter in Discoverer Desktop when i run the report.
In the custom folder query i have this piece in the where clause
WHERE tnfo.request_id = NVL(APPS.SETPARAM.GET_PARAM1,7383588)
And everytime i get the data pertaining to request id =7383588,
Please suggest where i went wrong
thanks

Updating a database using XML SQL Utility

Hi all,
It seems that the Oracle XML SQL Utility provides only to insert rows into a table/view. However, if one wants to update a table from an XML no support is available.
How does one proceed if this is to be achieved?
Thanks in advance.
Regards,

While inserting i get a
oracle.xml.sql.OracleXMLSQLException and further a
NumberFormatException. Which parameter do I have to set to avoid
these Exceptions. I can insert the file in my local db but I get
the Exception on the server db. The value I want to insert for
expample is 30,1. Maybe the JDBC-Driver tries to convert the String ;30,1+ to an
Integer-Object. This will cause the described Exception since
the Integer-Class requires ;.+ instead of ;,+ for decimal point.
I have another problem generating an xmlfile when there
are "Umlaute" in the data. E.g. V and \. Exchanging these to Oe
and Ue than it works fine.Use ISO-8859-1 character set to work with umlauts, e.g.:
<?xml version = '1.0' encoding = 'ISO-8859-1'?>
.. but you can use the default UTF-8 encoding too, umlauts will
be replaced by equivalents as ;CŸ+

Linked server query using Dynamic SQL

I have a Linked server query that takes forever to run. WHen I hardcode the acct# it runs fast. However I want these acct numbers int he where clause to be generated dynamically. For eg: below is what I need:
--Get the 11 Loans from this Table A From the FIRST QUERY
--- Plug those loans numbers in the second query In the WHERE Clause eg should looks like where ACCT in (1,2,3,5)
DECLARE
@sSQL varChar(MAX)
SET @sSQL
=
' SELECT
[Loan] FROM TableA D
EXECUTE(@sSQL)
--2ND QUERY
DECLARE
@sSQL1 varChar(MAX)
SET @sSQL1
='
SELECT Field1,
Field2,
Field3,
Field4,
Field5
FROM LinkedServer.Dbaname.dbo.TableB a
where ACCT in ''('''
+(@sSQL)
+
''')'''--- This needs to look like where ACCT in (1,2,3,5)
select
@sSQL1

Ok, so use this.. instead of your first statement.
DECLARE @sSQL NvarChar(MAX), @output NVARCHAR(100), @ParmDefinition nvarchar(500);
SET @ParmDefinition = N'@sqlout NVARCHAR(100) OUTPUT'
SET @sSQL = N'SELECT DISTINCT @sqlout = STUFF((SELECT '',''+CAST(S2.loan AS VARCHAR(100))
FROM tableA S2
FOR XML PATH('''')), 1, 1, '''')
FROM tableA S1'
EXECUTE sp_executesql @sSQL, @parmdefinition, @sqlout = @output OUTPUT
and use @output instead of @sSQL in the second statement.
You can read about STUFF command @

Good Luck :)

Query using the SQL 'go' command on a JAVA code

Hi,
I am trying to create a new database on MS SQL and at the same time verify whether the data base exist already and then add a new table. The query statement works well on the query windows on MS SQL, but when the query is place using a JAVA code it gives the following error:
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'go'.
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'go'.

Ok, first of all thanks for your answer, now what I want to do is the following:
1) I need to input ((retrieve) every minute some data (Date and Temperature), that I will get from and external device, this is not part of this code.
2) I want to store that data (Date and Temp) on a data base, here where I need the command to create the data base and to verify whether that data base already exists. In case it has already been created then create new table(s) on it. If it doesn't exist then create and then create new tables.
3) Each Day (at yyyy mm dd 00:00:00:000 will create a new table, and the name of this table will be yyyymmdd.
4) Then every minute the java code will retrieve the data and add it to the table in the data base.
5) That will be a close loop that will be running until the user interrupt it.
I haven't make the communication code yet, in order to test my code I was thinking to retrieve the data from another data base. This would be just to verify that the JAVA sequence is able to retrieve the data every minute and create new data base and tables.
For the record I am able to send the queries and retrieve information from SQL running the code in eclipse, that will cover your first observation.
I am quite new in the forum I am sorry I didn't get the use of code tags.
Sorry again as I said I am quite new on this, what's a DDL statement.
Thanks.

JDBC Query using PL/SQL

I have gotten this to work in my Reports class but can not get this to work at my company. Basically I'm trying to use the JDBC query in Report Builder.
Here is my Ref Cursor Code:
CREATE OR REPLACE PACKAGE SCOTT.types is
type sqlcur is REF cursor;
end;
Here is my Pl/SQL function:
CREATE OR REPLACE FUNCTION SCOTT.test return Scott.types.sqlcur is
c1 Scott.types.sqlcur;
begin
open c1 for select * from scott.emp;
return c1;
end;
I can get this to work in SQL Plus by doing the following:
var r refcursor
exec :r := test;
print r When I go into Reports Builder->JDBC query I connect to the SCOTT db using tiger as the password. I type in the function name TEST and get the error "wrong number or types of arguments in call TEST". I have tried "call TEST" but that doesnt work either. If I use "call TEST" I get an error saying it expected characters ":=(@" etc....
I know my connection works because I can do a "select * from emp" and get results. Can anyone get this to work?
I'm running Report Builder 9.0.2.0.3
I have done multiple searches on this issue and most responses point someone to links that dont work or documentation. I have read them and my code above should work but doesnt........Please put some real examples or code that works with the "Scott" schema.
Thanks

hi Shawn
When running jdbc quesry based on SP with Oracle DB, the first parameter of the store procedure should be of ref cursor type and it shall be a OUT parameter.
For example:
CREATE OR REPLACE PACKAGE jdbcpdspkg AS
TYPE Empcur IS ref cursor ;
procedure proc_with_param (p_emp_cv out jdbcpdspkg .empcur, p1 in number, p2 in number , p3 in number, p4 in number , p5 in number) ;
Thanks

Querying using Native SQL

Hi Pals,
I have a requirement which I would like to brief.
I have an internal table with columns FIELD1 and FIELD2. For all the values in FIELD1 I have to query a table MSI(which does not form a part of the R/3 framework) through Native SQL statement and get the corresponding values for FIELD2.
Could anybody suggest how I must proceed writing my statements between EXEC and ENDEXEC.
Do I have to query the database table for each entry in my internal table or is it possible to use for all entries in my SQL statemnt.
Your inputs would be highly appreciated.
Thank You in advance.
Regards,
Gayathri N.

Hai Gayathri
check this document
EXEC SQL.
Addition
... PERFORMING form
Effect
Executes the Native SQL command enclosed by the statements EXEC SQL and ENDEXEC . In contrast to Open SQL , addressed database tables do not have to be known to the ABAP/4 Dictionary and the ABAP/4 program does not have to contain appropriate TABLES statements.
Example
Create the table AVERI_CLNT :
EXEC SQL.
CREATE TABLE AVERI_CLNT (
         CLIENT   CHAR(3) NOT NULL,
         ARG1     CHAR(3) NOT NULL,
         ARG2     CHAR(3) NOT NULL,
         FUNCTION CHAR(10) NOT NULL,
         PRIMARY KEY (CLIENT, ARG1, ARG2)
ENDEXEC.
With Native SQL commands, passing data between an ABAP/4 program and the database is achieved using host variables . A host variable is an ABAP/4 variable prefixed by a "*" in the Native SQL statement.
Example
Display a section of the table AVERI_CLNT :
DATA: F1(3), F2(3), F3(3).
F3 = ' 1 '
EXEC SQL.
SELECT CLIENT, ARG1 INTO :F1, :F2 FROM AVERI_CLNT
         WHERE ARG2 = :F3
ENDEXEC.
WRITE: / F1, F2.
To simplify the spelling of INTO lists in the SELECT command, you can specify a single structure as the target area as in Open SQL .
Example
Display a section of the table AVERI_CLNT :
DATA: BEGIN OF WA,
        CLIENT(3), ARG1(3), ARG2(3),
      END OF WA.
DATA F3(3).
F3 = ' 1 '
EXEC SQL.
SELECT CLIENT, ARG1 INTO :WA FROM AVERI_CLNT
         WHERE ARG2 = :F3
ENDEXEC.
WRITE: / WA-CLIENT, WA-ARG1.
Notes
In contrast to Open SQL , a client field in Native SQL is a field like any other and must be specified explicitly in calls.
Authorization checks cannot be properly realized in EXEC SQL . You should perform these in the program.
When you start the R/3 System, a CONNECT to the current database is executed automatically. An explicit CONNECT is unnecessary.
A Native SQL command can (but does not have to) end with a ";". Under no circumstances should it end with a ".".
Some database systems allow upper and lower case in table names and field names. If you want to take advantage of this, you must ensure that the spelling of names is correct. To enable entry of lower case letters in names in the ABAP/4 editor, you must set the attribute for upper/lower case in the report.
Since there are no arrays in ABAP/4 , array operations are not possible in Native SQL . If the result of a SELECT command is a table, you can read this table line by line either with the Native SQL command FETCH or with the addition ... PERFORMING form .
Unlike in ABAP/4 programs, the character " in a Native SQL statement does not introduce a comment until the end of the editor line.
Addition
... PERFORMING form
Effect
If the result of a SELECT command is a table, you can read this table line by line in a processing loop. The subroutine form is called once for each line. In this subroutine, you can leave the loop by using EXIT FROM SQL . If the result of the selection is a single record, the subroutine is called only once.
Example
Display a section of the table AVERI_CLNT :
DATA: F1(3), F2(3), F3(3).
F3 = ' 1 '
EXEC SQL PERFORMING WRITE_AVERI_CLNT.
SELECT CLIENT, ARG1 INTO :F1, :F2 FROM AVERI_CLNT
         WHERE ARG2 = :F3
ENDEXEC.
FORM WRITE_AVERI_CLNT.
WRITE: / F1, F2.
ENDFORM.
Note
This addition is allowed only with a SELECT command.
Related SELECT , INSERT , UPDATE , MODIFY , DELETE , OPEN CURSOR , FETCH , CLOSE CURSOR, COMMIT WORK and ROLLBACK WORK .
go to se38
type 'EXEC' and put cursor on 'EXEC' press f1-function key
then you get help for EXEC

Crosstab query using PL/SQL [HELP]

hi all,
i got this output after execute my query:
week no | department | item | budget
1 | 0901 | salary | 25000
1 | 0901 | stationery | 5000
1 | 5501 | salary | 45000
2 | 0901 | salary | 25000
2 | 5501 | salary | 25000
2 | 5501 | stationery | 100
i hope to get the output like below:
dept/week no 1 2 3
=========================================
0901 30,000 25,000 800 (A)
5501 45,000 25,100 100 (B)
variance 45,000 70,000 70,800 (C)
=========================================
Grand total - 75,000 - 50,100 - (D)
======================================
NOTE:
the week is from week 1 until week 52, is it advisable to use looping or??.
It is more than 2 departments and items as well. the user is allowed to passing in more than 1 selection of the items (salary,stationary,hardware and software, etc) to get this report.
I need to display the output on the screen/spool into file after the execution.
==========
Definition
===========
Grant total (D1) by week =(A1 + B1)
Variance (C1) for the 1st week of the year will always take the (B1) values as the based values for the next calculation. whereas (C2) = (C1) + (A2) and (C3) =(C2)+(A3) and the same formular apply up to week 52.
the pivot method not a suitable solution to produce this output.
anyone can suggest the shorter and more intelligent solution?
this is very urgent, pls help!! thank

You can get your basic data by,
SELECT department, week_no, sum(budget) AS budget
FROM your_table
GROUP BY department, week_no;Then you'll just pivot the above data by week. Then you can use an analytic SUM() to get your weekly totals.
WITH your_table AS (
SELECT '0901' AS department, 1 AS week_no, 1000 AS budget FROM dual
UNION ALL
SELECT '1234' AS department, 1 AS week_no, 500 AS budget FROM dual)
SELECT v.*,
SUM(budget) OVER (PARTITION BY week_no) AS week_total
FROM (
SELECT department, week_no, sum(budget) AS budget
FROM your_table
GROUP BY department, week_no
ORDER BY department, week_no
) v;I have to admit I'm a bit confused about your definition of variance.

Forming query using xml forest

Hi,
I need the code for the following. I did try...but getting additional tags.
Create table patient (pat_mrn varchar2(100)) ; Create table encount (pat_mrn varchar2(100), encounter_id varchar2(1000)); Create table oper (encounter_id varchar2(1000), comp_name varchar2(1000)); Insert into patient values ('63280'); Insert into encount values ('63280', '42'); Insert into oper values (42, 'sugar'); Insert into oper values (42, 'sbp'); Insert into oper values (42, 'dbp'); CREATE OR REPLACE TYPE COMPONENT AS OBJECT ( "ID" VARCHAR2(1000)); CREATE OR REPLACE TYPE component_list_t AS TABLE OF COMPONENT; CREATE OR REPLACE TYPE cm_results_o_t AS OBJECT (RES_LIST component_list_t); O/p required : <Patient> <pat_mrn> 63280 </pat_mrn> <Results> <Component> <ID>sugar</ID> </Component> <Component> <ID>sbp</ID> </Component> <Component> <ID>dbp</ID> </Component> </Results> </patient>
Code I wrote :
Select P.PAT_MRN, XMLELEMENT("Patient", (XMLELEMENT("pat_mrn", P.pat_mrn)), (XMLELEMENT("Results", XMLForest(cm_results_o_t(CAST(MULTISET (SELECT O.COMP_NAME AS "ID" FROM oper O WHERE O.ENCOUNTER_ID = E.ENCOUNTER_ID) AS component_list_t)) AS "Results")))) AS Orderxml FROM PATIENT P JOIN ENCOUNT E ON P.PAT_MRN = E.PAT_MRN AND P.PAT_MRN = '63280' AND E.ENCOUNTER_ID = 42
So, we can clearly see there are lot of additional tags .. o/p i am getting
<Patient> <pat_mrn>63280</pat_mrn> <Results> <Results> <RES_LIST> <COMPONENT> <ID>sugar</ID> </COMPONENT> <COMPONENT> <ID>sbp</ID> </COMPONENT> <COMPONENT> <ID>dbp</ID> </COMPONENT> </RES_LIST> </Results> </Results> </Patient>
I am new to xml..So, any help is appreciated.
Thanks.

I modified the code :
[code]
Select P.PAT_MRN,
 XMLELEMENT("Patient",
 (XMLELEMENT("pat_mrn", P.pat_mrn)),
 (XMLForest(cm_results_o_t(CAST(MULTISET
 (SELECT O.COMP_NAME AS "ID"
 FROM oper O
 WHERE O.ENCOUNTER_ID =
 E.ENCOUNTER_ID) AS
 component_list_t)) AS
 "Results"))) AS Orderxml
 FROM PATIENT P
 JOIN ENCOUNT E
 ON P.PAT_MRN = E.PAT_MRN
 AND P.PAT_MRN = '63280'
 AND E.ENCOUNTER_ID = 42
[/code]
Need the Res_LIST tag to be removed which is coming from object type.

XML SQL utility

Hi,
When I try to execute this query using XML SQL utility
I am getting the following error. I had declared 'XMLGEN &
GETXML' as CLOB and tried but got the same error. Advice me. I
am struggling to find the solution using XSQL Servlet..but
couldn't get..I spend one week on that..no results...this is the
second trial. Is there any online help or service to do that.
xmlString := xmlgen.getXML('select * from scott.emp');
ERROR at line 9:
ORA-06550: line 9, column 16:
PLS-00201: identifier 'XMLGEN.GETXML' must be declared
ORA-06550: line 9, column 3:
PL/SQL: Statement ignored
I have Oracle XML parser for Java 2, and XML SQL utility and
oracle 8i database....
This is the query.........(Your example)
declare
xmlString CLOB;
amount integer:= 4000;
position integer := 1;
charString varchar2(4000);
i binary_integer := 0;
inclDTD number := 0;
begin
xmlString := xmlgen.getXML('select * from scott.emp');
dbms_lob.open(xmlString,DBMS_LOB.LOB_READONLY);
loop
dbms_lob.read(xmlString,amount,position,charString);
dbms_output.put_line(charString);
position := position + amount;
end loop;
exception
when no_data_found then
dbms_lob.close(xmlString);
dbms_lob.freetemporary(xmlString);
end;
null

Have you loaded the xmlgenpkg.sql in the schema in which you
are trying to execute your PL/SQL block?
