SPARQL query with OPTIONAL

Hi,
When I run a SPARQL query with OPTIONAL in the WHERE clause, I saw a lot of "select 1 from ***" kind of queries got executed. The query runs very slow. I'm running Jena adaptor 2 against Oracle 11.1.0.6. We have about half million triples in the model. The queries we need to run tend to be complex and they run pretty slow. Does Oracle 11.1.0.7 have big query performance improvement over 11.1.0.6? Is there anything that we can do on the application side or on the database side to boost the query performance? Thanks,
Weihua

Native database support for OPTIONAL in SEM_MATCH based RDF query has been made available via patch 7600122 on 11.1.0.7. Direct use of SEM_MATCH to query your data from SQL has significant performance benefits.

Input Readiness of Query with optional variables

Hi,
I built one input ready query which is input ready upon execution with only one set of selections, for any other set of selections, it is not input ready.Query is built on aggregation level on the top of multiprovider. There are no data slices built, No lock entries in RSPLSE as well. Is it like if a variable in the selection screen of the query is optional, will it be moved to free characteristic and because of that input readiness of the query will disappear?? In my case, country is authorized variable which is optional. Please let me know if any one has solution for this.
Thanks,
Bindu

Hi,
Check if:
1. You have added characteristic InfoProvider in filter area and restricted that to your plan cube?
2. Any Keyfigure in query will have input-ready cell only if all the characterictics in the aggregation level of that query has unique values for that cell.
In your case you have moved Country to free characteristic area and might have not provided any value for it as it's optional. So system is not finding a unique value for this characteristic for input-ready cells.
Enter value for Country variable and then execute, query will be input-ready.

Create SAP B1 Query with Optional User Input Fields

Hi All... any help is greatly appreciated, I am new to this forum and hope to contribute in the near future once I become more of an expert with B1.
I have a query I need to build that will search about 10 UDF's. The problem is, I don't know how to make the user input fields optional within the query. Currently, I have the following queries as testing searching 2 UDF"s:
SELECT T0.[ItemCode], T0.[ItemName], T0.[OnHand] FROM OITM T0 WHERE T0.[U_Quality] = [%0] OR T0.[U_LengthFT] =[%1]
This query works when leaving one of the user input fields blank. However, the values it provides are wrong because it is an OR statement which will show item codes with a certain quality OR a certain size.
The following query is the same as above but switched the OR to AND:
SELECT T0.[ItemCode], T0.[ItemName], T0.[OnHand] FROM OITM T0 WHERE T0.[U_Quality] = [%0] AND T0.[U_LengthFT] =[%1]
This query provides me with the correct values but will not work if one of the user defined fields is not filled out.
How do I go about getting the results I want and not having the user fill out all the UDF's for the query to execute properly?

I think I figured it out
SELECT T0.ItemCode, T0.ItemName, T0.OnHand
FROM OITM T0
WHERE (T0.U_Quality = '[%0]' OR '[$0]' = '0') AND (T0.U_LengthFT ='[%1]' OR '[%1]' = '0')
SAP must be defaulting empty user input field values to "0"
I tried the above query and it worked!!!
Is there anything you can add if I am missing something?
Thanks, Alec.

Select query with optional where condition

Hi,
Can Anybody help me out in the following problem?
I have the following query in a procedure.
SELECT replace(shipper_name,'\',' ') as shipper,
sum(teus / cntSailings) as teus
FROM VW_CONTRIBUTION,
VW_TOTAL_SAILINGS
WHERE VW_CONTRIBUTION.dir = VW_TOTAL_SAILINGS.DIR
AND VW_CONTRIBUTION.line = VW_TOTAL_SAILINGS.LINE
AND VW_CONTRIBUTION.accounting_month = VW_TOTAL_SAILINGS.ACCOUNTING_MONTH
AND VW_CONTRIBUTION.accounting_year = VW_TOTAL_SAILINGS.ACCOUNTING_YEAR
AND VW_CONTRIBUTION.Principal = arg_principal
AND VW_CONTRIBUTION.Dir = arg_direction
AND VW_CONTRIBUTION.line in ( arg_service )
AND VW_CONTRIBUTION.POL_country = arg_pol
AND VW_CONTRIBUTION.POd_country = arg_pod
AND VW_CONTRIBUTION.salesOffice = arg_SalesOffice
AND VW_CONTRIBUTION.salesregion = arg_SalesRegion
AND VW_CONTRIBUTION.cargo_type = arg_txtCargoType
AND VW_CONTRIBUTION.eqgroup = arg_ContType
AND VW_CONTRIBUTION.eq_size = arg_txtSize
AND VW_CONTRIBUTION.acct_date between arg_from_date and arg_end_date
GROUP BY shipper_name
ORDER BY teus desc;
Here some of the arguments are optional(Eg : VW_CONTRIBUTION.salesOffice, AND VW_CONTRIBUTION.eqgroup etc. ) and the values can be null. When they are null, I want them to be excluded from the where condition. Can anybody suggest me a solution for this?
Thanks,
Shalet.

I guess i misunderstood your original question.
The clause
AND (VW_CONTRIBUTION.salesOffice = arg_SalesOffice OR VW_CONTRIBUTION.salesOffice IS NOT NULL)
will cause the where clause to evaluate to FALSE anytime salesOffice IS NULL so the record will be excluded.
I thought you were asking how to not compare the value if the field contained a NULL.
Glad you found what you wanted.

Single quote in SPARQL query

Hi,
I have a SPARQL query with a clause like (?affy gb:bioprocess "3\'-phosphoadenosine" .). Oracle Jena adapter translates it into
sdo_rdf_match('(?affy <gb#bioprocess> "3\'||chr(39)||'-phosphoadenosine")..., which throws the following error when executing the query:
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: oracle.spatial.rdf.server.TokenMgrError: Lexical error at line 1, column 50. Encountered: "\'" (39), after : "\"3\\"
ORA-06512: at "MDSYS.RDF_MATCH_IMPL_T", line 169
ORA-06512: at "MDSYS.RDF_MATCH_IMPL_T", line 35
ORA-06512: at line 4
What does Oracle Jena adapter expect if the SPARQL query has single quote in the literal value? Thanks,
Weihua

Hi,
What is your database version?
Could you list exactly the literal value you want to query? Please ignore any escapes. Is it as follows?
3'-phosphoadenosine
Thanks,

11g OLAP cube MV's with Query Rewrite option

Hi All,
I am trying to test the 11g OLAP cube MV's with the Query Rewrite option.
I had created a cube on the schema OLAPTRAIN problem by oracle. I an selected necessary options in 'Materialized Views' tab of the Cube definition in AWM. here is the screenshot
!http://i40.tinypic.com/9jzpte.png!
and then I try to run the SQL query
select SUM(S.QUANTITY) AS QUAN,
SUM(S.SALES) AS SALES,
T.CALENDAR_YEAR_NAME,
P.DEPARTMENT_NAME,
C.COUNTRY_NAME
FROM
TIMES T,CUSTOMERS C,PRODUCTS P, SALES_FACT S
WHERE
C.CUSTOMER_KEY = S.CUSTOMER AND
T.DAY_KEY = S.DAY_KEY AND
P.ITEM_KEY = S.PRODUCT
group by T.CALENDAR_YEAR_NAME, P.DEPARTMENT_NAME, C.COUNTRY_NAME;
and observed the Explain plan, it is not using OLAP cube built, instead it is using the relational tables given in the above sql query.
Also, i have observed that , though enabling or disabling of the Query Rewrite option doesn't make any change in the Explain query for the above query.
alter materialized view olaptrain.cb$sales_cube enable query rewrite;
alter materialized view OLAPTRAIN.cb$sales_cube disable query rewrite;
No idea why is this Query Rewrite feature is not working on my Database instance of 11g R2 . Do am I missing any steps that has be taken care of , to make this working. Any inputs would be appreciated.
Thanks

Input Query with blanks when we press transfer values option

I have an input query with 12 restricted key figures, but when I enter data and press on 'Transfer Values' or 'Save Values', the cells are blanked out (i.e. the values dissapear) and the data is not updated into the cube. I have done the following:
In Query Designer, I have checked the attribute 'Start Query in Change Mode' and
For all restricted key figures that needs to be planned, I have marked as 'Data can be changed using user entries and planning functions...'
Can you please let me know your thoughts around this.
Thanks,
Srini

Mayank,
I have 10 characterstics(cost center, cost element, cost type, fiscal year period,fiscal year, version, value type, posting period, detail valye type, currency type+1kf(0amount)) in my aggregation level.
I have created 12 rkf for each month with the following restrictions
Plan rkf (sub rkf) with restrictions to
fiscal year(variable), inforprovider-real time cube, value type 20, kf-0amount,
jan plan rkf.....dec plan rkf has
kf--Plan rkf(sub rkf) + posting period 1...12(one for each month),
And i have created an input query with the following fields
unders rows
Cost type, cost element
under Columns
Jan paln rkf to Dec plan rkf
filters for controlling area EA
I have change the query defination to "start query change mode" and also set all the rkf properties to "change by user enteries and/or planning options"
So, is there anything i am missing here?
Do i have to all characterstics of my aggregation level in my input query? or do i have to restrct my rkf to any curreny/unit fields? Please shed some light in here....:)
Thanks for your help...

How does this LINQ query work with Option Infer Off?

How should value and filtered be declared? It doesn't work when I turn Option Infer Off. Originally, it worked with Option Infer On. There was no Dim statement on the first line, but the Dim keyword was placed before the
filtered = line. As soon as I turned Option Infer Off, all sorts of errors showed up. How should the code be adjusted? (Option Strict is On.)
Dim element, value, filtered As Integer
Dim values() As Integer = {2, 9, 5, 0, 3, 7, 1, 4, 8, 6}
filtered =
From value In values
Where (value > 4)
Select value
For Each element In filtered
Console.Write(element & " ")
Next
Solitaire

Hi Solitaire,
the Option Infer Off version would be:
Option Strict On
Option Infer Off
Imports System
Imports System.Collections.Generic
Imports System.Linq
Public Class Class1
Public Shared Sub LinqWithNoInfer()
Dim values() As Integer = {2, 9, 5, 0, 3, 7, 1, 4, 8, 6}
' compiled to
' filtered = values.Where(Function(value As Integer) value > 4).Select(Function(value As Integer) value)
value)
Dim filtered As IEnumerable(Of Integer) =
From value In values
Where (value > 4)
Select value
For Each element As Integer In filtered
Console.Write(element & " ")
Next
End Sub
End Class
The type for filtered is determined by the Select statement, that is
Enumerable.Select, and will return an
IEnumerable(Of T) and T is an Integer here.
Option Infer looks for the return value of Select and will give the same result.
Note: For Lambda Expressions Option Infer Off is ignored and the type is inferred - both are valid:
filtered = values.Where(Function(value) value > 4).Select(Function(value) value)
filtered = values.Where(Function(value As Integer) value > 4).Select(Function(value As Integer) value)

Hierarchy on HANA Calculation View with Optional Input Parameters Fails

Hi,
Has anyone succeeded in building a hierarchy on top of a calculation view with optional input parameters, where an input parameter is not filled?
The original requirement came from the wish to create a parent child hierarchy on a calculation view that was copied into the customer space from a HANA Live Financial Statement query view, but I have found the following when creating a simple level hierarchy on a calculation view that consumes one table. The Calculation View has one Input Parameter where the 'mandatory' box is unchecked.
Calculation view reads ECC table FAGLFLEXT
Simple level based hierarchy on fields PRCTR, RACCT and SEGMENT
Input parameter is used as a filter for PRCTR with logic ("EMPTY" = '$$P_PROFITCTR$$' or "PRCTR" = '$$P_PROFITCTR$$')
When I run the view I see the following behaviour in HANA Studio and Analysis for Excel
Before building the hierarchy I could run the view with or without the Input Parameter
After building the hierarchy I can run the view with the Input Parameter filled, but it fails when the Input Parameter is not filled.
Error message is "error: search table error: [2426] missing placeholder; missing value for mandatory parameter P_PROFITCTR"
P_PROFITCTR is not a mandatory parameter, but the selection for the hierarchy view thinks it should be. I don't find any notes around this issue, so I don't think it's version related, however the version I have used for this test is 1.00.70.
It's a shame we can't currently build the hierarchy as the parent child relationship is provided in HANA Live view NewGLFinancialStatementQuery.
Thanks,
Ken

Hi Ken,
We have been facing similar issue. We have even tried to set default value and as optional parameter. View still fails to create hierarchy (we are not using HANA live). As mentioned on page 97 of HANA modelling guide input parameter is mandatory from engine point of view. Hierarchy is generated as column view during the initial activation of calculation view and therefore expect a value by caller.
This seems to be a product error. Some one from HANA development team should explain this issue in detail. I would expect someone like Thomas Jung reply to us.
At the moment, we cant use input parameter for date prompt which gives us calendar popup feature for date selection. Hierarchies just don't work with input parameter. We are missing something.

BI 7.0 : Refresh of only one Query with VBA in a MultiQueryWorkbook

Does anyone know how to refresh only one query with VBA in a Workbook with several queries on different sheets?

Hello together,
thanks for your replies.
In the backend EHP1 is installed and I think we don't need an extra update for the frontend. But in the VBA code of the frontend the code didn't changed.
Our BEX Analyzer Addin version is: 7100.4.1100.34
BEx Patch Level is: Support Package 11 Revision 1606
The VBA code is:
Public Function SAPBEXrefresh(allQueries As Boolean, Optional atCell As Range) As Integer
'In the 7.0 Analyzer, ALL the items in the workbook can be refreshed, but refreshing
'a query individually is not supported
On Error Resume Next
extErrorBegin ("3.x API SAPBEXRefresh called")
If allQueries = True Then
    Common.MenuRefresh
    SAPBEXrefresh = 0
Else
    SAPBEXrefresh = 700
    p_extErrorText = "With 7.0, this API is partly supported to refresh ALL items in the workbook, NOT an individual Query"
End If
extErrorEnd
End Function
As you can see a individually query with this VBA code is still not supported.
Does anyone know how to change this code or if we need a special update?

Input query with dynamic actual & forecast values by month per year

Hello,
I am working on a Input ready query for a forecasting application which shows both actuals and forecast numbers and the user will revise the forecast numbers by month
Requirement: I want to build a Input query for monthly forecasting for the current year. It will be dynamic rolling of months with actuals & forecast data.
E.g. My report has 12 months for the current year
and if run the report in May, the months before May has to show the actuals and the months after May has to show the old forecast data so that the user will revise the numbers again in each month and save the data to the real time cube.
Jan.Feb.Mar.Apr.May.Jun.Jul.Aug.Sept.Nov.Dec
Act Act Act Act Act Old frcst for the remaining months
user will revise forecast for these months
So, i am able to create Input query with all restricted key figures( plan kf has change mode set to change, actual kf are not set change) and calculate key figures and all the logic is done on dynamically moving/rolling the data based on the input month of the year.
But the problem is that i am using cal kf to dynamically roll months, i was not able to set the change option for the cal kf.
So, how can i make sure that the dynamically changed plan months will open for entering forecast and the actuals months not to change?
Do you guys have any better solutions in implementing it?
I really appreciate it your input....:)
Thanks,
Srini

Hi,
Please look at the following DOC which may be useful to you and if so please grant me point.

Input-Ready Query
Use
You use input-ready queries to create applications for manual planning. These can range from simple data entry scenarios to complex planning applications.
Integration
You define a query that you want to use for manual planning in the BEx Query Designer (see Defining New Queries).
In the Web Application Designer or the BEx Analyzer, you can combine the input-ready queries with other queries and planning functions to create complex planning applications.
Prerequisites
You can define an input-ready query on any of the following InfoProviders:
●     Aggregation levels (see Aggregation Levels)
●     MultiProviders that include at least one simple aggregation level
The aggregation levels are created in the planning modeler; MultiProviders are defined in the modeling functional area of the Data Warehousing Workbench.
Features
Definition of an Input-Ready Query
Once you have defined a query on an InfoProvider, you see the Planning tab page under the Properties of structural components (for example, in key figures or restricted key figures). The options provided there allow you to determine which structural components of an input-ready query are to be input ready at runtime and which are not. With structural components that are not input ready, you can also determine whether these components are viewed as reference data or are just protected against manual entry.
For the structural components, you also have the following options:
Input readiness of structural components of a query
Option
Description
Not input ready (reference data)
If they are being used as reference data, the structural components are not protected by data locks to ensure exclusive access for one user because this data serves as a reference for many users.
This is the default setting.
Not input ready (no reference data)
If you want to protect structural components against manual entries but allow changes by planning functions, you can use locks to protect this data for one particular user. In this way you can ensure that the planning function works with the displayed data only and not with data that has been changed by other users.
Input ready
You can also determine whether an input ready query is to be started in change mode or in display mode. You find this property in the Query Properties on the Planning tab page. If there is at least one input-ready query component, the query (as long as it has not been determined otherwise) is started in display mode.
In BI applications that use input ready queries as data providers, you can enter data manually at runtime. For more information, see Performing Manual Planning and Creation of Planning Applications.
Example
You want to create an input-ready query for manual planning for a plan-actual comparison of revenues for a set of products. You want the plan data in a real-time-enabled InfoCube and the actual data in a standard InfoCube.
       1.      Create a MultiProvider that includes the InfoCubes for the plan and actual data.
       2.      Define an aggregation level on the MultiProvider which contains the characteristic Product and the key figure Revenue.
       3.      On the aggregation level, create two restricted key figures Plan Revenue and Actual Revenue. For restriction, choose the characteristic 0INFOPROV and restrict it to the plan or actual InfoCube.
       4.      Add the restricted key figures to the key figure structure. Insert Product into the rows. For Plan Revenue, choose Input Ready for the input-readiness option. For Actual Revenue, choose the option Not Input Ready (Reference Data).
       5.      In the query properties, set the indicator that determines whether the queries are started in display or change mode as required.
Example of an input-ready query
Product
Plan Revenue
Actual Revenue
P01
20
P02
30
If you want to keep actual and plan data in a real-time enabled InfoCube, you do not require a MultiProvider for the task described above. Create an aggregation level on the InfoCube and define the input-ready query for the aggregation level. In the example above, a version characteristic acts as the InfoProvider. Create restricted key figures with the plan or actual version and proceed as in the previous example.

Linking Access tables, creating a query with using both Access and Oracle

Hello,
I am using 3.0.04.34 version Oracle Developer. I am supposed to create a script/procedure to use both Access tables and oracle tables together. There is an option in developer to copy the access tables into oracle. But it doesn't help me. Because when we updated the access tables
the copied ones are not be updated. How can I created a linked access tables to oracle and create a query with using both access and oracle table together.
I will appreciate if you guys help me. I look forward to hearing from you guys.
Thanks,
Pinar

Pinar,
to be able to query MS Access tables in Oracle you need an additional product, the Oracle Database Gateway for ODBC. It allows you to link any foreign database into an Oracle database using a suitable ODBC driver. You can then access the MS Access tables through a database link based on the Database Gateway for ODBC. This will also allow you to join local Oracle and remote MS Access tables from your Oracle database.
There's a note on My Oracle Support which gives you more details:Document 233876.1 Options for Connecting to Foreign Data Stores and Non-Oracle Databases - For example - DB2, SQL*Server, Sybase, Informix, Teradata, MySQL
And there's also a dedicated Forum: Heterogeneous Connectivity

i think this error is connected with partitoning
in the first version i put any_interact into view with read only option
select * from this view works fine but take a long time,
next i build theme in MapBuider but preview return error (same), (MapBuilder buid query on view and add query_window filter to reduce number of objects)

Materialized views - query rewrite -- optional joins & dimensions

Hi,
I've implemented a number of materialized views that are accessible via query rewrite.
Most of these views make use of duplicate tables (DD_TIME table is joined via purchase, load, process, ... date columns)
I've also created a dimension to make Oracle aware of the time relation (month is child of year...)
The issue:
--> If I create the mat. view with inner joins, query rewrite works with the dimensions, but I need to provide ALL joined tables in the query
--> If I create the mat. view with outer joins, query rewrite works even with 1 joined table, but the dimension seems to be ignored
How can I create 'optional' joins in the Mat. View while making use of dimensions for rollup?
(the limitations on materialized view delta joins mentioned on [oracle docs|http://docs.oracle.com/cd/B28359_01/server.111/b28313/qradv.htm#autoId16] kinda has me worried)
Example Mat. View:
CREATE MATERIALIZED VIEW DA_REPOSITORY_MERCHANT_MM
... ENABLE QUERY REWRITE
AS SELECT
DDFPC.YEAR_NO,
DDFPC.YEAR_MONTH,
DDPUR.YEAR_NO,
DDPUR.YEAR_MONTH,
SUM( DF.TRANSACTION_AMOUNT )
FROM DF_REP DF,
DD_TIME DDFPC,
DD_TIME DDPUR
WHERE DF.FPC_DTE = DDFPC.DAY_DATE(+)
AND DF.PUR_DTE = DDPUR.DAY_DATE(+)
GROUP BY
DDFPC.YEAR_NO,
DDFPC.YEAR_MONTH,
DDPUR.YEAR_NO,
DDPUR.YEAR_MONTH
Example query launched:
SELECT
DDFPC.YEAR_NO,
SUM( DF.TRANSACTION_AMOUNT )
FROM DF_REP DF,
DD_TIME DDFPC
WHERE DF.FPC_DTE = DDFPC.DAY_DATE
GROUP BY
DDFPC.YEAR_NO

The problem was resolved by setting foreign keys in the fact table and making them not nullable + using inner joins.
--> this informs oracle there can be no difference between a query without the dimensions and a query with the dimensions.
As a result, the materialized view can contain 1 fact linked to 2 dimension tables, but the query rewrite will work for queries on the 1 fact joined with only 1 dimension
