How to use dynamic select query which queries from 3 different table.

Hi All,
I am new to Toplink, i would like to use a named query to select some of the columns from 3 different tables with dynamic where clause.
I have used the following lines. Please tell me how to get code for the dynamic where clause.
First try :
Vector objPersons = (Vector)session.executeQuery("findPersonByGlobalID",Person.class,vQueryArguments);
The above method is not returning the vector or collection.
Second Try:
ReadAllQuery query = new ReadAllQuery(Person.class);
query.useCollectionClass(LinkedList.class);
LinkedList person = (LinkedList) session.executeQuery(query);
The second try is returning the collection but, this fetches all the record from the table.
1. How to query for range of records?
2. How to query from multiple tables for some range. How to use dynamic range values ?
Please reply with your answers or some pointers would help.
Thanks and Regards,
Vijay.B

Hi,
Did you try using a SQLCall ? It might be able to satisfy you requirements .. :-
Employee employee = (Employee) session.executeSelectingCall(
new SQLCall("SELECT * FROM EMPLOYEE WHERE EMP_ID = 44")
);You can get more information here :-

How to use Xpath to query elements loaded from different xml docs?

I have a big DBLP XML doc (95mb), to load into the container, i splitted the doc into many small xml docs by the publication types, such as articles, books, inproceedings, etc.
I tried to use xpath query such as
query 'collection()/dblp[article/author]/book[title]'
I got empty answers.
but if i use XQuery such as
query 'let $r:=collection()/dblp,$a :=$r/inproceedings/author
for $l2 in $r/book
where $a and $l2/title
return <result> {$l2}{$a}</result>'
i got answers. However, if i remove {$a} from the return clause, i still got empty answers.
is there any problem with my Xpath query and flwor Xquery?

Hi John,
Following is the procedure i have used to load the xml docs (after the indexes have been created):
private static void loadXmlFiles(File path2DbEnv,String theContainer, File file) throws Throwable {
     //Open a container in the db environment
          XmlManager theMgr = null;
          XmlContainer openedContainer = null;
          myDbEnv env;
          try {
          env = new myDbEnv(path2DbEnv);
     theMgr = new XmlManager(env.getEnvironment(), new XmlManagerConfig());
     //use node container
     theMgr.setDefaultContainerType(XmlContainer.NodeContainer);
               try{
               openedContainer = theMgr.createContainer(theContainer);
               }catch (XmlException e){
                    //if the container alreay exist, then open it;
                    openedContainer = theMgr.openContainer(theContainer);
          //Get an update context.
          XmlUpdateContext updateContext = theMgr.createUpdateContext();
               String theFile = file.toString();
               String docName=file.getName();
          //Get the input stream.
          XmlInputStream theStream = theMgr.createLocalFileInputStream(theFile);
          System.out.println("Adding " + theFile + " to container " +
                         theContainer);
     //     Do the actual put
          openedContainer.putDocument(docName, // The document's name
          theStream, // The actual document.
          updateContext, // The update context
     //     (required).
          null); // XmlDocumentConfig object
          System.out.println("done.");
          //XmlException extends DatabaseException, which in turn extends Exception.
          // Catching Exception catches them all.
          } catch (XmlException e){
               System.err.println("Error loading files into container " + theContainer);
               System.err.println(" Message: " + e.getMessage());
               //In the event of an error, we abort the operation
               // The database is left in the same state as it was in before
               // we started this operation.
               throw e;
          finally {
          cleanup(theMgr, openedContainer);
Unfortunately, i waited for around 20 hours 148mb doc was not loaded; so i gave up.
Could you please give me some suggestions on how to load the large doc efficiently ? thanks.

How to build dynamic select query

Using the ZCO_SETTLE_CHK-REC_FIELD and DISTRIBUTION_RULE-KONTY write a dynamic select single query <table>-<field name> e.g. <COAS>- <AUART> on the <table> e.g. <COAS>. If the DISTRIBUTION_RULE-KONTY is u2018ORu2019, then use DISTRIBUTION_RULE-AUFNR value in the where clause of the query to fetch the ZCO_SETTLE_CHK-REC_FIELD value maintained in the <table>-<field name>. If DISTRIBUTION_RULE-KONTY = u2018KSu2019 or u2018PRu2019 use DISTRIBUTION_RULE-KOSTL or DISTRIBUTION_RULE- PS_PSP_PNR respectively in the where clause to fetch the values.
For above how we can build dynamic query

Hi,
Refer the below code which helps to design a dynamic where condition.
IF NOT p1 IS INITIAL.
CLEAR : lv_p1_condition.
CONCATENATE 'F1' ' = ' '''' p1 '''' INTO
lv_p1_condition.
ENDIF.
IF NOT p2 IS INITIAL.
CLEAR : lv_p2_condition.
CONCATENATE 'F2' ' = ' '''' p2 '''' INTO
lv_p2_condition.
ENDIF.
IF NOT p3 IS INITIAL.
CLEAR : lv_p3_condition.
CONCATENATE 'F3' ' = ' '''' p3 '''' INTO
lv_p3_condition.
ENDIF.
IF NOT lv_p1_condition IS INITIAL.
CONCATENATE lv_p1_condition lv_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
IF NOT lv_p2_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p2_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p2_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
IF NOT lv_p3_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p3_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p3_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
SELECT * FROM link INTO wa

HR-How to use dynamic selection fields in prog ..?

Hii
I have written a prog to select data pertaining to details of all employees who belong to a particular country . For this i have provided a dynamic selection field for selecting country (through Selection View).But when i am getting all the records for all countries.
How to use the dynamic selection fields in program or they behave in the same way as the standard selection given by the LDB .As if we enter a value in the std screen then the GET event acts accordingly .
Ajitabh Pradhan

Hi Ajitabh,
First off, is the Dynamic Selection working? If so, try the following code.. I am assuming, you only want to look at Permanent Address.
tables: pernr.
infotypes: 0001,0006.
start-of-selection.
get pernr.
rp-provide-from-last p0001 space pn-begda pn-endda.
check pnp-sw-found eq 1.
rp-provide-from-last p0006 1 pn-begda pn-endda.
check pnp-sw-found eq 1.
write:/ pernr-pernr,p0001-ename,p0006-land1.
end-of-selection.

How to Query Multiple Fields from different Tables using Toplink Expression

Hi,
I am trying to prepare an Oracle Toplink Expression to qurey the multiple columns of different tables. the query as following. Please can anyone help?
SELECT CYCLE.CYCLE_ID,
CYCLE.ASPCUSTOMER_ID,
CYCLE.FACILITYHEADER_ID,
CYCLE.ADDUSER,
ASP.FIRSTNAME || ' ' || ASP.LASTNAME ADDUSERNAME,
CYCLE.ADDDATE,

and then i want to send that expression to readAllObjects method as a parameter
Expression exp = (..............this is the required qurey expression...................)
Vector employees = session.readAllObjects(getClass(), exp);
thanks,

You havent given any information on the mapping between Cycle and Asp. I presume there is a one to one mapping between them. Also it appears there is no "WHERE" clause to limit the number of cycles being retrieved. If that is the case then I presume you want to load all cycles in the system.
Thats just a clientSession.readAllObjects(Cycle.class). If you have indirection turned on the Asp should get loaded when you do a cycle.getAsp().
I presume that SQL you posted loads all the columns of CYCLE and ASP. If you are interested in a subset of CYCLE or ASP then you should do a ReportQuery or partial object read.

Select query for fetching from 3 tables.

Can we have a single Select query for fetching same fields (kappl,kschl,vkorg,vtweg,spart,kunwe,datbi,knuma,datab,knumh)
from 3 tables >> KOTE707,KOTE708 and KOTE709 into an internal table for a particular KUNNR?
Regards,
Shashank.

Hi,
If you have kunnr field in all the 3 tables then it is possible. use inner join as below
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
            p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
         fldate TYPE sflight-fldate,
         carrname TYPE scarr-carrname,
         connid   TYPE spfli-connid,
       END OF wa.
DATA itab LIKE SORTED TABLE OF wa
               WITH UNIQUE KEY fldate carrname connid.
SELECT c~carrname p~connid f~fldate
       INTO CORRESPONDING FIELDS OF TABLE itab
       FROM ( ( scarr AS c
         INNER JOIN spfli AS p ON p~carrid   = c~carrid
                              AND p~cityfrom = p_cityfr
                              AND p~cityto   = p_cityto )
         INNER JOIN sflight AS f ON f~carrid = p~carrid
                                AND f~connid = p~connid ).
LOOP AT itab INTO wa.

How do I use Aggregate formulas with multiple measures from different tables?

I have three measures:
Cash - this sums the £ column in my 'Cash' table.
Online - this sums the £ column in my 'Online'
table
Phone - this sums the £ column in my 'Phone'
table
How do I now do aggregate formulas that combine this three measures, for example:
Find the MIN or MAX of the three measures
Average the three measures
I have worked out how to use simple aggregation like add, subtract etc through the CALCULATION formula, but doing the average or MIN/MAX does not work.
Thanks.

Hi, thanks for the suggestions.
Re: Julian
I had thought about this method, unfortunately it is not always three measures so this doesn't work.
Re: Tim
I was not aware of the APPEND formula however I will definitely give it a try and report back - I can see this one working.
Re: Michael
Apologies, I have never found a an easy way of simulating some of my issues since it would mean creating a new power model and establishing quite a number of relationships. I definitely see the benefit when posting on the forum since it makes my issue far more
accessible, unfortunately when I've posted before I've generally been racing against time and not had time to prepare this anonymised data. Is there a quick way of doing it?

How to use a SELECT QUERY using fdmAPI.executeDML in FDMEE Jython Script?

Hi,
Just the way we use DELETE and INSERT Statement using fdmAPI.executeDML, is there any way of executing a SELECT Statement and get the output in variables?
I would like to refrain from using import java.sql and enter the connection details in a script.I would like to rather use SELECT directly if possible. I want to read the TDATASEG.DATAKEY column and use it for some custom process in a custom table
Thanks!

Hi SH,
Somehow after upgrading to FDMEE 11.1.2.3.530, this is not working.
I get an error saying
while (RSTxnType.Next()):
Attribute Error: 'oracle.jdbc.driver.OracleResultSetImpl' object has no attribute 'Next'

Search help for a field using a selection method which has a text table.

Hello all,
I am trying to create a search help for one of the fields in a structure say RFCDEST. Now for this i am giving the selection method as the DB table where all the RFCDEST are maintained. However there is a text table which is also comes up for this selection method and the description of the filed RFCDEST is in that text table and the description is not stored in the main table which i specified as the selection method.
My query is that on F4 now all the rfc destinations are being shown however the description i am not able to show them because there is no field in the table specified in the selectionmethod which hold s the description but instead it is there in the text table, how can i fetch the description from there and display in the search help.
Warm Regards,
Naveen M

look at search help FC_RFCDEST. that problem has already been solved with this search help.

How to use Field-symbol with dynamic select query

Can anybody tell me, how to use field-symbols in the dynamic select query.

FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
The FIELD-SYMBOLS statement declares a field symbol <fs>. The name conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
eg.
FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
        string1(10) VALUE '0123456789',
        string2(10) VALUE 'abcdefghij',
      END OF line.
WRITE / line-string1+5.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.
output:
56789
56789

How to create a Type Object with Dynamic select query columns in a Function

Hi Every One,
I'm trying to figure out how to write a piplined function that executes a dynamic select query and construct a Type Object in order to assigned it to the pipe row.
I have tried by
SELECT a.DB_QUERY INTO actual_query FROM mytable a WHERE a.country_code = 'US';
c :=DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(c,actual_query,DBMS_SQL.NATIVE);
l_status := DBMS_SQL.EXECUTE(c);
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
FOR j in 1..col_cnt LOOP
DBMS_SQL.DEFINE_COLUMN(c,j,v_val,2000);
END LOOP;
FOR j in 1..col_cnt LOOP
DBMS_SQL.COLUMN_VALUE(c,j,v_val);
END LOOP;
But got stuck, how to iterate the values and assign to a Type Object from the cursor. Can any one guide me how to do the process.
Thanks,
mallikj2

Hi Justin,
First of thanks for your reply, and coming to my requirement, I need to report the list of items which are there in the dynamic select statement what am getting from the DB. The select statement number of columns may vary in my example for different countries the select item columns count is different. For US its '15', for UK it may be 10 ...like so, and some of the column value might be a combination or calculation part of other table columns (The select query contains more than one table in the from clause).
In order to execute the dynamic select statement and return the result i choose to write a function which will parse the cursor for dynamic query and then iterate the values and construct a Type Object and append it to the pipe row.
Am relatively very new for these sort of things, welcome in case of any suggestions to make it simple (Instead of the function what i thought to work with) also a sample narrating the new procedure will be appreciated.
Thanks in Advance,
mallikj2.

How to use multi select in a query report

I defined a lov. This lov retuns name and a id. I want to use the result of this multi select in my query.
I always get invalid number when I choose two items of the select. When I debug I see that the return value of the multi select is 1:2. How can I change the seperator : in , I tried the following but this does't work.
if :P26_PRODUCTTYPE IS NOT NULL then
l_sql := l_sql ||' and producttype in
(REPLACE(:p26_producttype,'':'','','' ))';
end if;

as you're finding, multiple values selected from html db multi-select list items (and checkboxes) are stored as a single, colon-delimited string. i explained an easy way to handle this via pl/sql in...
Multiple select list
...that post shows you how to throw the selected values into a pl/sql table and step through them as needed. it also showed how to use an instr to parse through the string if you want to go that route. you could use that same instr logic right in your sql query. so let's say your lov for your multi-select item (P1_MY_MULTISELECT, we'll call it) was defined as...
select ename, empno from emp order by 1
...and your user selected KING, FORD, and JONES. :P1_MY_MULTISELECT would store those values as...
7839:7902:7566
...you could then write a query to return the selected enames with something like...
select ename, job
from emp
where insrt (':'||:P1_MY_MULTISELECT||':',':'||empno||':') != 0
...hope this helps,
raj
