Query.....mapping
have 2 tables
1) Table X with 5 columns.
2) Table Y with 2 columns
Table Y: Column 1 à Position of the columns in Table X
Table Y: Column 2 à It has the data as column names of table X
Is there any way to map the column names in Table Y with the columns in Table X ??????
Your question is not very clear, but I think you should look up dynamic sql...

Table for Webtemplate and Query mapping
Hi Experts,
Is there any table which has the mapping for BW Web template and the Query on which this Web Template is built.
Any help would be highly appreciated.

Hi,
Thanks for the reply.
What is the output for this report?
I just need the query name which is used for creating the Web Template.
Any table, FM or ABAP program for getting the query name for a Web Template will be sufficient for my requirement.

SQL Query - Mapping Groups to Batches
I am using Oracle 11g Release 2.
I have the following dataset:
CREATE TABLE RoomGroups
(group_id NUMBER,
group_name VARCHAR2(30),
group_capacity NUMBER);
INSERT INTO RoomGroups VALUES(1, 'SEECS UG Block', 100);
INSERT INTO RoomGroups VALUES(2, 'IAEC Building', 70);
INSERT INTO RoomGroups VALUES(3, 'RIMMS Building', 90);
Commit;
CREATE TABLE DegreeBatches
(batch_id NUMBER, batch_name VARCHAR2(30), batch_strength NUMBER);
INSERT INTO DegreeBatches VALUES(10,'BIT-10',35);
INSERT INTO DegreeBatches VALUES(20,'BIT-11',40);
INSERT INTO DegreeBatches VALUES(30,'BSCS-2',35);
INSERT INTO DegreeBatches VALUES(40,'BSCS-3',40);
INSERT INTO DegreeBatches VALUES(50,'BEE-4',50);
INSERT INTO DegreeBatches VALUES(60,'BICSE-7',25);
INSERT INTO DegreeBatches VALUES(70,'BESE-3',30);
Commit;
I want to achieve the following thr single or multiple SQL queries:
Firstly, get all possible sets of DegreeBatches for each group - in such a way that for each set the SUM(batch_strength) <= Capacity of that group as show below.
GroupId Batches StrengthStr StrengthTotal Capacity
1. {BIT-10, BIT-11, BICSE-7} {35, 40, 25} 100 100
1. {BSCS-2, BSCS-3, BICSE-7} {35, 40, 25} 100 100
1. {BEE-4, BSCS-3} {50, 40} 90 100
2. {BIT-10, BSCS-2} {35, 35} 70 70
2. {BSCS-3, BESE-3} {40, 30} 70 70
2. {BIT-11, BICSE-7} {40, 25} 65 70
and so on...
Secondly, I want to retrieve only non-overlapping sets based on minimum value of Capacity-StrengthTotal for each group
GroupId Batches StrengthStr StrengthTotal Capacity
1. {BIT-10, BIT-11, BICSE-7} {35, 40, 25} 100 100
2. {BSCS-3, BESE-3} {40, 30} 70 70
3. {BSCS-2, BEE-4} {35, 50} 85 90
And finally, the final result must have all the batches in it...
Which in this case is true...
Any help will be highly appreciated...
Thanks

Dynamic Query Mapping using Toplink Entity
Hi,
We have a requirement that the column names of the table dynamically gets changed for different customers.
eg;
Client 1 , will have
Select EMP_ID, EMP_NAME from EMPLOYEE
Client 2 will have
SELECT CEMP_ID, EMP_NAME, CEMP_ADDR from EMPLOYEE
Is it possible to make a Toplink Entity Employee object to support both the queries at runtime ?ie; we should not modify the java entity object for each customer.
With normal JDBC , we can perform SELECT * from EMPLOYEE ,get the resultset , and using metadata , we can find the column names and process it accordingly.
Is this functionality possible with toplink JPA at all ?
Thanks
prabuHi,
I am trying to use DynamicEntity class. Is Joined Table Inheritance supported in DynamicEntity ? Since I need to create an HybridEntity on the fly by selecting all the fields from TABLE A and TABLE B by joining key fields, whose fields will dynamically change based upon the customer. Below is what I am currently trying to do. But the Entity Object that I got contains fields only from TABLE A and not from TABLE B
EntityManagerFactory emf = new EntityManagerFactoryImpl(setup,EclipseLinkJPATest.getEMFProperties());
SchemaManager manager = new SchemaManager(JpaHelper.getServerSession(emf));
Vector <DatabaseRecord>tableAEntityFieldNames = manager.getAllColumnNames("TABLE A");
Vector <DatabaseRecord>tableBFieldNames = manager.getAllColumnNames("TABLE B");
EntityType tableAType = EntityTypeFactory.create("TableAEntity","DynamicEntity$TableAEntity", "TABLE A", loader);
String columnName = null;
for(DatabaseRecord tableAObj: tableAEntityFieldNames){
columnName = tableAObj.get("COLUMN_NAME").toString();
EntityTypeFactory.addBasicProperty(tableAType, columnName, columnName,
"TABLE A_ID".equals(columnName) ? Long.class : String.class, "TABLE A_ID".equals(columnName) ? true : false);
EntityTypeFactory.addToPersistenceUnit(emf, tableAType);
EntityType stepType = EntityTypeFactory.create("TableBEntity","DynamicEntity$TableBEntity", "TABLE B", loader);
for(DatabaseRecord tableBObj: tableBEntityFieldNames) {
columnName = tableBObj.get("COLUMN_NAME").toString();
EntityTypeFactory.addBasicProperty(tableBType, columnName, columnName,"TABLE B_ID".equals(columnName) ? Long.class : String.class, "TABLE B_ID".equals(columnName) ? true : false);
EntityTypeFactory.addToPersistenceUnit(emf, tableBType);
EntityManager em = emf.createEntityManager();
List <DynamicEntity> entityList = null;
entityList = em.createQuery("select s from TableAEntity s, TableBEntity st where s.TABLE A_ID= st.TABLE B_IDand s.TABLE A_ID=?1")
.setParameter(1, 1397)
.getResultList();
System.out.println("entityList..."+entityList);

Unable to find Searchable Item in Query Criteria Map
Hi ,
Am try to personalize Advacned Search Region to Include new search Criteria in R12 iSupplier Portal->Home->Orders Tab->Advanced search.
Am trying to create new search field in the Add another row field through personalization.
I have created new row criteria,when am trying to create Query Criteria Map,Am unable to list the Searchable Item as it is Drop down list.
This causing unable to query the records based on the newly created row criteria item.
Please advise.
Thansk<Sarath.Hi Jobnish,
There is no code in this requirement.
There is no error...Issue is unable to query data based on newly create criteria row in Advanced search.
I can give you navigation:
iSupplier Portal->Home->Orders Tab->Press advanced search Region
Click on the Personalize Page(I hope you know how to enable the personalize link using profile option).
In SupplierRN ->Advanced Search Criteria and creating custom item Criteria Row..
We need to map this field in Advanced Query Mapping.
However the issue is the Am unbale find the Searchable item (which is created in Criteria Row) in the drop downlist.
I can provide screen-shot if you need.
Thanks,Sarath. -
Mapping an object's property to a field computed from 2 database fields
Hi,
Is there a way to do a WorkBench mapping of a business object's property to a field computed from 2 separate database fields?
If not in WB, how would you do that?
Thanks,
MichalYou could define this mapping through a TransformationMapping using you own code in the mappings transformer to divide the values. However you are probably much better off to just map the two values directly, and add a method in your object model to get the rate buy dividing the values.
If terms of being able to order-by the calculated value in the a TopLink query, mapping the calculated value using a transformation mapping would not help this.
To do this order by you can use,
query.addOrdering(ExpressionMath.multiply(ExpressionMath.divide(builder.get("numberOfSuccess"), builder.get("numberOfAttempts")), 100); -
Hi,
I need to query an oracle database using bind variables. To do so, I have a method to execute any query, that would receive the query in a "SELECT fieldFROM table WHERE id = :param1" fashion, and a list of the params for the binded variables in the where clause. This params them need to be set by its type's corresponding method, for example, ints would use the preparedStatement.setInt(index, integer) method.
I might try to receive as the parameters list an object of type List<Object> and then map the each item in the list with instance of, for every method declared in the PreparedStatement interface, like
if (parametro instanceof Short) {
statement.setShort(index, (Short) parametro);
}but surely there is a better way...
Since this would be used by any query, would you suggest to design it as a class where all related methods to execute the query, map the fields to set methods, and, transform result sets into domain objects live?
Thanks in advance.I have fixed a template method structure where the abstract class is holding the executeQuery method, that will first call a method to prepare de query, then set the paramethers for the query and finally delegate de execute query on the preparedStatement. Both the prepareQuery and the setParameters methods are left for the extending classes to implement, so they will know what method on PreparedStatement to use to add the named variables with its right type.

Hello,
I have issue with workbook.
I have workbook with 5 queries.
I've replaced all 5 queries to another queries and delete old queries from server after saving workbook with new queries.
Now I'm opening workbook, entering login and password and face error:
Requested Query ZFI_M11/ZZFI_M09_Q009 doesn't exist on server.
If I choose Ok nothing happend, workbook wouldn't open.
It's strange, because I couldn't delete query from server, before I've delete it from workbook and technical name of query is strange, it has / symbol.
I tried to create query with ZZFI_M09_Q009 name, but it doesn't help me.
How I can open workbook to fix it?
Regards,
RomanoHi
If the specified query is not intended to use in that work book, remove / delete the workbook - Query Mapping, then work book would work appropriately.
and If you are using BI7 work book, in design mode of workbook identify which are the BEx objects are accessing the query and correct them to right infoprovider.
In BI7 Workbook - settings you can view the List of Data Providers used in that work book. so you can validate and correct the data provides mapping to respective elements in workbook
If you are using the BW 3.5, check the queries used in Metadata repository and remove the mapping for deleted query from the work book.
Best Wishes,

How to execute query after login?
Hi Gurus,
I'm developing nowadays a small system,that shows every employee his data( attendance time,vacations,execuses..etc),I just want to execute query (pop up data) once the employee logged in,as I get his login name and sysdate and execute the query.
how could this happen? do I need a process ? what is it?
How to get the system date?
thanks in advance
Pardon me,am just new here and still my terms for Developer 2000.You can do it with a process (call it onload) or with a simple sql query mapped to a region in the home page of your application.
hope this helps -
As I understand it, I created my Cubes using Analytical Workspace Manager, so we can consider its metadata as Standard Form and call it Active Catalog.
In contrast, if I created my cubes using OEM(as SYSDBA), or OWB, my metadata would've been confusingly called OLAP Catalog Metadata that consists of ordinary relational tables.
Fortunate for OLAP Catalog Metadata users, they can query Mapping information using OLAP Catalog Mapping Views.
I was wondering if I can also query Mapping information for Active Catalog...
Does anyone know how or which "Active Catalog View" to query (to know which dimension/cube is mapped to a certain table)?Hi Swetha,
In my opinion this may be due to a timeout in mapping process. Which CCM SP level are you running?.
Have you had a look to the SAP Note 926007?.
I hope this help.

The query
Part 1:
This Query maps the seat_id in the master table with each time slot and with effective start date between sysdate-60 and sysdate+365 assuming that a seat can be allocated not more than a year. so if there are 10 seats in this table then this table contains 10*48*425 records
SELECT mst.seat_id
, cal.sl_no
, cal.cal_day
, tm.s_no
, tm.from_time
, tm.to_time
FROM xxcgs_adm_seat_mst mst
, xxcgs_admin_calendar cal
, time_slots tm
WHERE cal.cal_day >= NVL (mst.effective_start,SYSDATE - 60)
AND cal.cal_day <= NVL (mst.effective_end, SYSDATE + 365)
I created a view TEST_MST_V on the above query
Part 2:
This query is based on the allocation table and it checks the allocated seats with all the time slots and between the allocated date range and marks the timeslot as 0 if it is not allocated and 1 if it is allocated
SELECT seat_id
, sl_no
, cal_day
, s_no
, from_time
, to_time
FROM
(SELECT alloc.seat_id
, cal.sl_no
, cal.cal_day
, tm.s_no
, tm.from_time
, tm.to_time
,SUM(DECODE(LEAST(alloc.time_from,tm.from_time),alloc.time_from,
DECODE(GREATESTalloc.time_to,tm.to_time),alloc.time_to, 1,0),0))AVAILABILITY
FROM
xxcgs_adm_allocation alloc
,xxcgs_admin_calendar cal
,time_slots tm
WHERE
cal.cal_day >= alloc.allocfrom_date
AND cal.cal_day <= alloc.allocto_date
GROUP BY alloc.seat_id
,cal.sl_no
,cal.cal_day
,tm.s_no
,tm.from_time
,tm.to_time
ORDER BY cal.sl_no, tm.s_no) a
WHERE a.AVAILABILITY = 1
I created TEST_ALLOC_V on the above query
Part 3:
Here i am substracting the 2nd query output from the 1st to get all the available time slots for all seats. In this i used the views created on the above 2 queries
SELECT seat_id
,sl_no
,cal_day
,s_no
,from_time
,to_time
FROM test_mst_v
MINUS
SELECT seat_id
, sl_no
, cal_day
, s_no
, from_time
, to_time
FROM test_alloc_v
WHERE AVAILABILITY = 1
Part 4:
I need to squeeze the time slots to get the available start time and available end time. For that i used the following query on the substracted data
SELECT seat_id
,sl_no
,cal_day
,MIN (s_no) min_s_no
,MAX (s_no) max_s_no
,MIN (from_time) min_time
,MAX (to_time) max_time
FROM
(SELECT
seat_id
,sl_no
,cal_day
,s_no
,prev_s_no
,from_time
,to_time
,COUNT (CASE WHEN prev_s_no IS NULL THEN 'x'
WHEN prev_s_no != s_no - 1 THEN 'x'
ELSE NULL
END)
OVER (PARTITION BY seat_id, sl_no ORDER BY s_no) grp
FROM (SELECT seat_id
,sl_no
,cal_day
,s_no
,from_time
,to_time,
LAG (s_no) OVER (PARTITION BY seat_id, sl_no ORDER BY s_no) prev_s_no
FROM(SELECT seat_id
,sl_no
,cal_day
,s_no
,from_time
,to_time
FROM test_mst_v
MINUS
SELECT seat_id
, sl_no
, cal_day
, s_no
, from_time
, to_time
FROM test_alloc_v
WHERE AVAILABILITY = 1)))
GROUP BY seat_id, sl_no, cal_day, grp
ORDER BY seat_id, cal_day
But this query is taking long time to fetch the data. Presently we have only 12 seats of data. For this it is taking 40 seconds to fetch the data. Once this project goes live we will have around 10000 seats in the XXCGS_ADM_SEAT_MST table.
I request any of the experts who can give me a solution based on the data i posted here to modify the query which produces the same results with better performance.
Thanks and Regards
DeekshitThe problem with your query is the approach to this problem. In the given query you are first expanding your data set to time slots and calculate with this rather huge set.
If you first calculate the gaps and do the expansion to days and time slots as a last step, you gain a lot:

Requirement is that enhanced the extractor by adding fields mapped the fields in bw in DSO,added in dimension in cube and also mapped in multiprovider ,this fields has to be reflected in report (not as a key figure) suggest how we can reflect it in report (need to create copy of existing query),mapping at data target level is done just need to create copy query and adding fields in reports ,how can achieve this
Hi,
After adding new Field/Fields to the multi provider, you can see those new fields under the Info provider tab in the left panel in query designer.
1)Now if you want to copy the same query to a totaly new query, click on Query from the Menu and then select save as give the technical name and description of the new query ,
2) Now drag and drop the newly added fileds to the multiprovider in to the query desinger. And finally save the query. -
Hi all
I'm wondering what the format of IF-ELSE block is in DI. I wan to check validation rules in my query in DI but my IF statement comes with an error. I searched a lot on the Internet but couldn't find the correct syntax. What I wrote is :
If dateOfBirth < sysdate()
datafobirth
end
Unfortunately there is no help for using functions in DI It takes me a lot to figure out the correct syntax!!
Any help is greatly appreciated.you can't put a block of logic in Query mapping, you mapping expression should evaluate to a value that will be assgined to the output column
for Query mapping you will either use constants or expressions along with input columns, or use functions, you either put the logic in a custom function or use thefunctions provided by DI . the DI functions are documented with examples in the technical manual
for you case you can use ifthenelse() function, or put the same logic in a custom function and call that here
for example:- in a Query your mapping can be, if your source is a EMP table with DOJ as date column
ifthenelse(EMP.DOJ < sysdate(), DOJ, NULL)
or you can take DOJ as input to custom function and return the output based on your requirement
Maybe you are looking for
