How to implement nexted query in BI answers

Is there any option to implement nested SQL in BI answer request ?
SQL , like
select d.ft,count(d.ft)
from
select my_id,min(event_time) ft
from my_table
group by my_id
) d
group by d.ft
order by d.ft;
Thank you.

I have solved this problem by creating a view inside the database and running BI report against the view.
But still i think that such a basic feature to run nested query or report should exist.

  • How to implement enter-query , execute-query in Apex Forms

    Hi,
    I am new to Oracle Application Express. I want to know what is the equivalent of ENTER-QUERY and EXECUTE-QUERY features of Oracle Forms in Oracle APEX? I saw a lot of documentation, but everywhere I found that APEX forms only have 3 database actions, (1) INSERT (2) UPDATE & (3) DELETE.
    Does anybody know how we can do QUERY in APEX Forms? (like we do in Oracle Developer Forms).
    Thanks in advance.

    Oracle APEX is a web/ stateless environment. So you do not have the same functionality/ features as in a Oracle Forms environment which is session/state oriented.
    You can however achieve functionality similar to Enter Query / Execute Query through other means.
    The easiest is to use the Forms with Report wizard. It creates 2 pages, the first one is a report and the other a Form. Clicking on the Report rows takes you to the Form page in Edit mode where as the the Create button takes you to the Form in Insert mode.
    If you want to have the enter-query / execute query on a single page it will require significant effort and skills. Try it when you have acquired some more skills in Apex.
    In APEX , like any other web application, you have to think in the web paradigm and not client-server. Even Forms 11g is essentially client-server like and is session oriented through the forms applet.

  • How to implement Quick Query and Saved Searches in ADF?

    We are using 11gR2 ADF.
    The requirement is to enable Quick Search and save the Searches.
    In the Oracle ADF documentation, it is mentioned that
    - Create a view with view criteria named.
    - In the .jspx drag and drop the view criteria and Select Quick Query
    Upon doing the above, we see that a Search panel is getting created, but with a message 'No Search Fields Added'.
    In the named view criteria, Under 'UI Hints' we have set
    -- execution mode as Both
    -- Search region mode is Basic
    -- Show Operators in Basic
    Under 'Criteria Definition'
    the attributes are added in a group with OR condition.
    Thanks for your reply. Oracle ADF developer guide does not help!!
    If you have any other documentation that helps in implementing this Quick Query and Saved Search, your help is greatly appreciated.

    Set the following on your af:query component
    SaveQueryMode = hidden
    ModeChangeVisible = false
    This should work for you ..

    thank you very much

    Hi Sony,
    if i really understood you, you will like to jump from one query to an ABAP Report or another Query.
    Here are the steps:
    1.Run T-code RSBBS.
    2.In the One Query tab enter the technical name of the Query
    3. In the One Query tab select or enter a technical name of a query

  • How to implement next line

    hi
    i ahve a problem
    in main window there are line items outputed in rows and columns seperated by vertical lines and horizontal lines
    now my requriment is that under a column say column3 i want an extra line to display some more data in that column only
    how to do it
    mean for all columns 1 column2 there will be n othing corresponding to that particlar row only in column3 data will be tehre rest all columns that data will be blank...
    my q
    wht is command to give next line under for that particlual columns
    and what tabs should i put to escape that data coming to columns 1 and columns2 only for column3 it should come
    how to give blank space for first two columns and reach the third columns what code to write in form
    regards

    Hi Nishant,
    I assume you want the output to be as follows.......
    S.No.---- Mat. No----Description
    01--A00101---LCD Screens, Monitors,
    Computing.
    02--A00102---Modems, Networking
    03--A00103---Mouse, I/O Devices,
    Computing.
    The simplest solution for your problem is, for column 3 (here Description), specify a left margin and a right margin. Say, you want the text to be printed at 7 inches from left of the page margin and should end at 10 inches from the page margin, go to paragraph format and create a new one with desired font type and size and specify a left margin with 7 inches and a right margin with 10 inches. The data will be restricted to that particular column and rest of the fields will be printed as per the TABs specified for them.
    Hope this clears your problem. If this was helpful, please award points.

  • How to implement this need help

    I created a datacontrol for a named query which (using Ejb entity beans) which accepted a employee id and click on find show me the respected employee details in a table.
    case 1: In one single page
    when i added the form consisting of a single text box , button and the table to show the result of the find method in one single page it worked out perfectly,,,
    case 2 : using 2 different pages
    But then i tried adding only the form in one page named page1 and and the table to show the result in another page i.e page2 , Also in the command action of find button of page1 i asked it to redirect to page 2 and show result . But it never showed me any results..
    Question :
    1) How to implement case2 i.e to have a form on one page and the resultant table to be show on another page i.e When users sees first page he adds the employee id in text box and clicks find .The user then needs to be redirected to page2 and the result of search should be shown in table...
    Can anyone guide me over this... ???

    Hi,
    you use a method on the EJB that takes a argument (e.g. the employee ID). You then put the method result set on page 2 (the method argument shall be pointed to a request or session attribute using EL : #{sessionScope.EmployeeId}
    On the search page - when the user hits the search button - you set the attribute "EmployeeId" in the session before navigating to the next page

  • How to Implement HTTP Request Status Code Processing

    I actually have two questions. First, I wondering how to add multiple status code processing to an http request. Secondly, I was wondering how to go about using alternate http requests to different servers in case the primary server is down. What kind of parameter would the program use to determine that the server is unavailable and switch to another server??
    Currently, the program I've written calls an rdf server (http://www.rdfabout.com/sparql) using a sparql query,
    the server returns an xml string, the program parses it, and calculates numbers
    from the string. The program works, but the problem is that the server is down occasionally.
    When the server is down, we need to add calls to another server to
    increase reliability. So, the next task is to call this server:
    http://www.melissadata.com/lookups/ZipDemo2000.asp
    I need to do exactly the same things I did with the rdf server. The
    difference will be constructing a request and a bit different parsing of
    the response.
    current SPARQL query is defined as follows:
    PREFIX dc:  <http://purl.org/dc/elements/1.1/>
    PREFIX census: <http://www.rdfabout.com/rdf/schema/census/>
    PREFIX census1: <tag:govshare.info,2005:rdf/census/details/100pct/>
    DESCRIBE ?table WHERE {
    <http://www.rdfabout.com/rdf/usgov/geo/census/zcta/90292> census:details
    ?details .
    ?details census1:totalPopulation ?table .
    ?table dc:title "SEX BY AGE (P012001)" .
    }current HTTP Request is defined as follows:

             int zip;//zipcode is declared as integer format
            //User defines zip through input

            conn.setDoOutput (true);
            conn.setUseCaches (false);

            DataOutputStream out = new DataOutputStream (conn.getOutputStream ());
            // Write out the bytes of the content string to the stream.
            out.writeBytes(requestPart1 + requestPart2 + requestPart3);

            temp = null;
            in.close ();
            //parsing stuff is taken care of after here
    }What remains now is to:
    1) add status code processing: notify if the server is not available, ect.
    2) add ability to connect to additional server if primary server is down.
    I'm thinking an if/else statement, which I've tried a few different ways,
    but I don't quite know how to implement that...Also trying to add the
    status code processing/error handling, but I'm not sure how to do that
    for multiple/different errors, such as 404, 503, 504, ect.. try/catch statements?
    So yeah, just been scratching my head on this trying to figure out how to work it..
    If you can help me out on this, I've been going nuts trying to figure this out...

    I think your issue comes form the fact that you are not casting URLConnection to HttpURLConnection.
    Doing the cast would allow you to use getResponseCode() - among other methods - and test for a response different than 200.

  • How to update this query and avoid performance issue?

    Hi, guys:
    I wonder how to update the following query to make it weekend day aware. My boss want the query to consider business days only. Below is just a portion of the query:
    select count(distinct cmv.invoicekey ) total ,'3' as type, 'VALID CALL DATE' as Category
    FROM cbwp_mv2 cmv
    where cmv.colresponse=1
    And Trunc(cmv.Invdate)  Between (Trunc(Sysdate)-1)-39 And (Trunc(Sysdate)-1)-37
    And Trunc(cmv.Whendate) Between cmv.Invdate+37 And cmv.Invdate+39the CBWP_MV2 is a materialized view to tune query. This query is written for a data warehouse application, the CBWP_MV2 will be updated every day evening. My boss wants the condition in the query to consider only business days, for example, if (Trunc(Sysdate)-1)-39 falls in weekend, I need to move the range begins from next coming business day, if (Trunc(Sysdate)-1)-37 falls in weekend, I need to move the range ends from next coming business day. but I should always keep the range within 3 business days. If there is overlap on weekend, always push to later business days.
    Question: how to implement it and avoid performance issue? I am afraid that if I use a function, it greatly reduce the performance. This view already contains more than 100K rows.
    thank you in advance!

    You are already using a function, since you're using TRUNC on invdate and whendate.
    If you have indexes on those columns, then they will not be used because of the TRUNC.
    Consider omitting the TRUNC or testing with Function Based Indexes.
    Regarding business days:
    If you search this forum, you'll find lots of examples.
    Here's another 'golden oldie': http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:185012348071

  • What is BI ? How we implement & what is the cost to implement ?

    What is BI ? How we implement & what is the cost to implement ?
    Thanks,
    Sumit.

    Hi Sumit,
                        Below is the description according to ur query
    Business Intelligence is a process for increasing the competitive advantage of a business by intelligent use of available data in decision making. This process is pictured below.
    The five key stages of Business Intelligence:
    1.     Data Sourcing
    2.     Data Analysis
    3.     Situation Awareness
    4.     Risk Assessment
    5.     Decision Support
    Data sourcing
    Business Intelligence is about extracting information from multiple sources of data. The data might be: text documents - e.g. memos or reports or email messages; photographs and images; sounds; formatted tables; web pages and URL lists. The key to data sourcing is to obtain the information in electronic form. So typical sources of data might include: scanners; digital cameras; database queries; web searches; computer file access; etcetera.
    Data analysis
    Business Intelligence is about synthesizing useful knowledge from collections of data. It is about estimating current trends, integrating and summarising disparate information, validating models of understanding, and predicting missing information or future trends. This process of data analysis is also called data mining or knowledge discovery. Typical analysis tools might use:-
    u2022     probability theory - e.g. classification, clustering and Bayesian networks; 
    u2022     statistical methods - e.g. regression; 
    u2022     operations research - e.g. queuing and scheduling; 
    u2022     artificial intelligence - e.g. neural networks and fuzzy logic.
    Situation awareness
    Business Intelligence is about filtering out irrelevant information, and setting the remaining information in the context of the business and its environment. The user needs the key items of information relevant to his or her needs, and summaries that are syntheses of all the relevant data (market forces, government policy etc.).  Situation awareness is the grasp of  the context in which to understand and make decisions.  Algorithms for situation assessment provide such syntheses automatically.
    Risk assessment
    Business Intelligence is about discovering what plausible actions might be taken, or decisions made, at different times. It is about helping you weigh up the current and future risk, cost or benefit of taking one action over another, or making one decision versus another. It is about inferring and summarising your best options or choices.
    Decision support
    Business Intelligence is about using information wisely.  It aims to provide warning you of important events, such as takeovers, market changes, and poor staff performance, so that you can take preventative steps. It seeks to help you analyse and make better business decisions, to improve sales or customer satisfaction or staff morale. It presents the information you need, when you need it.
    This section describes how we are using extraction, transformation and loading (ETL) processes and a data warehouse architecture to build our enterprise-wide data warehouse in incremental project steps. Before an enterprise-wide data warehouse could be delivered, an integrated architecture and a companion implementation methodology needed to be adopted. A productive and flexible tool set was also required to support ETL processes and the data warehouse architecture in a production service environment. The resulting data warehouse architecture has the following four principal components:
    u2022 Data Sources
    u2022 Data Warehouses
    u2022 Data Marts
    u2022 Publication Services
    ETL processing occurs between data sources and the data warehouse, between the data warehouse and data marts and may also be used within the data warehouse and data marts.
    Data Sources
    The university has a multitude of data sources residing in different Data Base Management System (DBMS) tables and non-DBMS data sets. To ensure that all relevant data source candidates were identified, a physical inventory and logical inventory was conducted. The compilation of these inventories ensures that we have an enterprise-wide view of the university data resource.
    The physical inventory was comprised of a review of DBMS cataloged tables as well as data sets used by business processes. These data sets had been identified through developing the enterprise-wide information needs model.
    3
    SUGI 30 Focus Session
    The logical inventory was constructed from u201Cbrain-stormingu201D sessions which focused on common key business terms which must be referenced when articulating the institutionu2019s vision and mission (strategic direction, goals, strategies, objectives and activities). Once the primary terms were identified, they were organized into directories such as u201CProjectu201D, u201CLocationu201D, u201CAcademic Entityu201D, u201CUniversity Personu201D, u201CBudget Envelopeu201D etc. Relationships were identified by recognizing u201Cnatural linkagesu201D within and among directories, and the u201Cdrill-downsu201D and u201Croll-upsu201D that were required to support u201Creport byu201D and u201Creport onu201D information hierarchies. This exercise allowed the directories to be sub-divided into hierarchies of business terms which were useful for presentation and validation purposes.
    We called this important deliverable the u201CConceptual Data Modelu201D (CDM) and it was used as the consolidated conceptual (paper) view of all of the Universityu2019s diverse data sources. The CDM was then subjected to a university-wide consultative process to solicit feedback and communicate to the university community that this model would be adopted by the Business Intelligence (BI) project as a governance model in managing the incremental development of its enterprise-wide data warehousing project.
    Data Warehouse
    This component of our data warehouse architecture (DWA) is used to supply quality data to the many different data marts in a flexible, consistent and cohesive manner. It is a u2018landing zoneu2019 for inbound data sources and an organizational and re-structuring area for implementing data, information and statistical modeling. This is where business rules which measure and enforce data quality standards for data collection in the source systems are tested and evaluated against appropriate data quality business rules/standards which are required to perform the data, information and statistical modeling described previously.
    Inbound data that does not meet data warehouse data quality business rules is not loaded into the data warehouse (for example, if a hierarchy is incomplete). While it is desirable for rejected and corrected records to occur in the operational system, if this is not possible then start dates for when the data can begin to be collected into the data warehouse may need to be adjusted in order to accommodate necessary source systems data entry u201Cre-worku201D. Existing systems and procedures may need modification in order to permanently accommodate required data warehouse data quality measures. Severe situations may occur in which new data entry collection transactions or entire systems will need to be either built or acquired.
    We have found that a powerful and flexible extraction, transformation and loading (ETL) process is to use Structured Query Language (SQL) views on host database management systems (DBMS) in conjunction with a good ETL tool such as SAS® ETL Studio. This tool enables you to perform the following tasks:
    u2022 The extraction of data from operational data stores
    u2022 The transformation of this data
    u2022 The loading of the extracted data into your data warehouse or data mart
    When the data source is a u201Cnon-DBMSu201D data set it may be advantageous to pre-convert this into a SAS® data set to standardize data warehouse metadata definitions. Then it may be captured by SAS® ETL Studio and included in the data warehouse along with any DBMS source tables using consistent metadata terms. SAS® data sets, non-SAS® data sets, and any DBMS table will provide the SAS® ETL tool with all of the necessary metadata required to facilitate productive extraction, transformation and loading (ETL) work.
    Having the ability to utilize standard structured query language (SQL) views on host DBMS systems and within SAS® is a great advantage for ETL processing. The views can serve as data quality filters without having to write any procedural code. The option exists to u201Cmaterializeu201D these views on the host systems or leave them u201Cun-materializedu201D on the hosts and u201Cmaterializeu201D them on the target data structure defined in the SAS® ETL process. These choices may be applied differentially depending upon whether you are working with u201Ccurrent onlyu201D or u201Ctime seriesu201D data. Different deployment configurations may be chosen based upon performance issues or cost considerations. The flexibility of choosing different deployment options based upon these factors is a considerable advantage.

    SUGI 30 Focus Session
    Data Marts
    This component of the data warehouse architecture may manifest as the following:
    u2022 Customer u201Cvisibleu201D relational tables
    u2022 OLAP cubes
    u2022 Pre-determined parameterized and non-parameterized reports
    u2022 Ad-hoc reports
    u2022 Spreadsheet applications with pre-populated work sheets and pivot tables
    u2022 Data visualization graphics
    u2022 Dashboard/scorecards for performance indicator applications
    Typically a business intelligence (BI) project may be scoped to deliver an agreed upon set of data marts in a project. Once these have been well specified, the conceptual data model (CDM) is used to determine what parts need to be built or used as a reference to conform the inbound data from any new project. After the detailed data mart specifications (DDMS) have been verified and the conceptual data model (CDM) components determined, a source and target logical data model (LDM) can be designed to integrate the detailed data mart specification (DDMS) and conceptual data model (CMD). An extraction, transformation and loading (ETL) process can then be set up and scheduled to populate the logical data models (LDM) from the required data sources and assist with any time series and data audit change control requirements.
    Over time as more and more data marts and logical data models (LDMu2019s) are built the conceptual data model (CDM) becomes more complete. One very important advantage to this implementation methodology is that the order of the data marts and logical data models can be entirely driven by project priority, project budget allocation and time-to-completion constraints/requirements. This data warehouse architecture implementation methodology does not need to dictate project priorities or project scope as long as the conceptual data model (CDM) exercise has been successfully completed before the first project request is initiated.

All of our canned reports generated through SAS® Enterprise Guide, along with a web-based query and reporting tool (SAS® Web Report Studio) will be accessed through this publication channel.
    Using the portalu2019s personalization features we have customized it for a McMaster u201Clook and feelu201D. Information is organized using pages and portlets and our stakeholders will have access to public pages along with private portlets based on role authorization rules. Stakeholders will also be able to access SAS® data sets from within Microsoft Word and Microsoft Excel using the SAS® Add-In for Microsoft Office. This tool will enable our stakeholders to execute stored processes (a SAS® program which is hosted on a server) and embed the results in their documents and spreadsheets. Within Excel, the SAS® Add-In can:
    u2022 Access and view SAS® data sources
    u2022 Access and view any other data source that is available from a SAS® server
    u2022 Analyze SAS® or Excel data using analytic tasks
    The SAS® Add-In for Microsoft Office will not be accessed through the SAS® Information Delivery Portal as this is a client component which will be installed on individual personal computers by members of our Client Services group. Future stages of the project will include interactive reports (drill-down through OLAP cubes) as well as balanced scorecards to measure performance indicators (through SAS® Strategic Performance Management software). This, along with event notification messages, will all be delivered through the SAS® Information Delivery Portal.
    Publication is also channeled according to audience with appropriate security and privacy rules.
    SECURITY u2013 AUTHENTICATION AND AUTHORIZATION
    The business value derived from using the SAS® Value Chain Analytics includes an authoritative and secure environment for data management and reporting. A data warehouse may be categorized as a u201Ccollection of integrated databases designed to support managerial decision making and problem solving functionsu201D and u201Ccontains both highly detailed and summarized historical data relating to various categories, subjects, or areasu201D. Implementation of the research funding data mart at McMaster has meant that our stakeholders now have electronic access to data which previously was not widely disseminated. Stakeholders are now able to gain timely access to this data in the form that best matches their current information needs. Security requirements are being addressed taking into consideration the following:
    u2022 Data identification
    u2022 Data classification
    u2022 Value of the data
    u2022 Identifying any data security vulnerabilities
    u2022 Identifying data protection measures and associated costs
    u2022 Selection of cost-effective security measures
    u2022 Evaluation of effectiveness of security measures
    At McMaster access to data involves both authentication and authorization. Authentication may be defined as the process of verifying the identity of a person or process within the guidelines of a specific
    6

    security policy (who you are). Authorization is the process of determining which permissions the user has for which resources (permissions). Authentication is also a prerequisite for authorization. At McMaster business intelligence (BI) services that are not public require a sign on with a single university-wide login identifier which is currently authenticated using the Microsoft Active Directory. After a successful authentication the SAS® university login identifier can be used by the SAS® Meta data server. No passwords are ever stored in SAS®. Future plans at the university call for this authentication to be done using Kerberos.
    At McMaster aggregate information will be open to all. Granular security is being implemented as required through a combination of SAS® Information Maps and stored processes. SAS® Information Maps consist of metadata that describe a data warehouse in business terms. Through using SAS® Information Map Studio which is an application used to create, edit and manage SAS® Information Maps, we will determine what data our stakeholders will be accessing through either SAS® Web Report Studio (ability to create reports) or SAS® Information Delivery Portal (ability to view only). Previously access to data residing in DB-2 tables was granted by creating views using structured query language (SQL). Information maps are much more powerful as they capture metadata about allowable usage and query generation rules. They also describe what can be done, are database independent and can cross databases and they hide the physical structure of the data from the business user. Since query code is generated in the background, the business user does not need to know structured query language (SQL). As well as using Information Maps, we will also be using SAS® stored processes to implement role based granular security.
    At the university some business intelligence (BI) services are targeted for particular roles such as researchers. The primary investigator role of a research project needs access to current and past research funding data at both the summary and detail levels for their research project. A SAS® stored process (a SAS® program which is hosted on a server) is used to determine the employee number of the login by checking a common university directory and then filtering the research data mart to selectively provide only the data that is relevant for the researcher who has signed onto the decision support portal.
    Other business intelligence (BI) services are targeted for particular roles such as Vice-Presidents, Deans, Chairs, Directors, Managers and their Staff. SAS® stored processes are used as described above with the exception that they filter data on the basis of positions and organizational affiliations. When individuals change jobs or new appointments occur the authorized business intelligence (BI) data will always be correctly presented.
    As the SAS® stored process can be executed from many environments (for example, SAS® Web Report Studio, SAS® Add-In for Microsoft Office, SAS® Enterprise Guide) authorization rules are consistently applied across all environments on a timely basis. There is also potential in the future to automatically customize web portals and event notifications based upon the particular role of the person who has signed onto the SAS® Information Delivery Portal.

    REPORTING
    We have created a number of parameterized stored processes using SAS® Enterprise Guide, which our stakeholders will access as both static (HTML as well as PDF documents) and interactive reports (drill-down) through SAS® Web Report Studio and the SAS® Add-In for Microsoft Office. All canned reports along with SAS® Web Report Studio will be accessed through the SAS® Information Delivery Portal.
    NEXT STEPS
    Next steps of the project include development of a financial data mart along with appropriate data quality standards, monthly frozen snapshots and implementation of university-wide financial reporting standards. This will facilitate electronic access to integrated financial information necessary for the development and maintenance of an integrated, multi-year financial planning framework. Canned reports to include monthly web-based financial statements, with drill-down capability along with budget templates automatically populated with data values and saved in different workbooks for different subgroups (for example by Department). The later will be accomplished using Microsoft Direct Data Exchange (DDE).

    As well, we will begin the implementation of SAS® Strategic Performance Management Software to support the performance measurement and monitoring initiative that is a fundamental component of McMasteru2019s strategic plan. This tool will assist in critically assessing and identifying meaningful and statistically relevant measures and indicators. This software can perform causal analyses among various measures within and across areas providing useful information on inter-relationships between factors and measures. As well as demonstrating how decisions in one area affect other areas, these cause-and-effect analyses can reveal both good performance drivers and also possible detractors and enable u2018evidenced-basedu2019 decision-making. Finally, the tool provides a balanced scorecard reporting format, designed to identify statistically significant trends and results that can be tailored to the specific goals, objectives and measures of the various operational areas of the University.
    LESSONS LEARNED
    Lessons learned include the importance of taking a consultative approach not only in assessing information needs, but also in building data hierarchies, understanding subject matter, and in prioritizing tasks to best support decision making and inform senior management. We found that a combination of training and mentoring (knowledge transfer) helped us accelerate learning the new tools. It was very important to ensure that time and resources were committed to complete the necessary planning and data quality initiatives prior to initiating the first project. When developing a project plan, it is important to
