• Materialized view, based on the stored procedure

  Hi all

  is it possible to create a materialized view on the results returned by a stored procedure?

  If this is not the case, do you think that any other way except for filling a table with data from the stored procedure and then founded the MV on it?

  Thanks in advance.

  Sorry I don't speak properly. In fact the procedure does not return a value, it fills one of its parameters (of the ref cursor type) of data. That's what I wanted.

  No it's not.

  REF CURSOR don't store data, so it's not possible.

  A Ref cursor is just a pointer to a query... and you can't "select from" a ref cursor, you can retrieve only one open.

  PL/SQL 101: Understand the Ref Cursor

  As correctly stated above, you can't question from a procedure to a function, and a materialized view is based on a query, you cannot use a procedure in a materialized view.

  You could use a function pipeline instead of a procedure, or have the pipeline function obtain the results of the procedure and pipelines, and then the materialized view could be based on the results of this function in the pipeline.

  example of function pipeline:

• Creating classic report to the stored procedure.

  How can we create a report based on a stored procedure out parameter.

  Can someone please help.

  Thank you

  Nani.

  Nani4850 wrote:

  Out parameter is a multi-level object type.

  I found a way to sort of basis a report on the parameter OUT procedure. The approach is:

  1. call the procedure in a process before PL/SQL areas, convert the object returned in an XML document and store in a collection XMLType column:

  declare
  
    k_rate_query varchar2(255) := 'RATE_QUERY';
  
    l_rate_type_code  number;
    l_rate_query      rate_rec;
    l_xml             xmltype;
  
    l_seq_id number;
  
  begin
  
    l_rate_type_code := to_number(:p1_rate_type_code);
    api_pkg.rate_query(l_rate_type_code, l_rate_query);
    l_xml := xmltype.createXML(l_rate_query);
  
    if not apex_collection.collection_exists(k_rate_query)
    then
      apex_collection.create_collection(k_rate_query);
    end if;
  
    select
        seq_id
    into
        l_seq_id
    from
        apex_collections
    where
        collection_name = k_rate_query
    and n001 = l_rate_type_code;
  
    apex_collection.update_member_attribute(k_rate_query, l_seq_id, 1, l_xml);
  
  exception
  
    when no_data_found
    then
      apex_collection.add_member(
          p_collection_name => k_rate_query
        , p_n001 => l_rate_type_code
        , p_xmltype001 => l_xml);
  
  end;
  

  2. use a SQL/XML query on the XML collection in the region report source:

  select
      rq.*
  from
      apex_collections ac
    , xmltable(
          '/RATE_REC/RATE_TBL/RATE_REC_TYPE'
          passing ac.xmltype001
          columns
              action_code         varchar2(20)  path 'ACTION_CODE'
            , rate_key            number        path 'RATE_KEY'
            , rate_type_code      varchar2(5)   path 'RATE_TYPE_CODE'
            , program_key         varchar2(12)  path 'PROGRAM_KEY'
            , rate                number(8,5)   path 'RATE'
            , effective_date      date          path 'EFFECTIVE_DATE'
            , current_yn          varchar2(1)   path 'CURRENT_YN'

• creating a dynamic list within a static list

  Hello

  I use 5 APEX with universal theme and so I have the static navigation on the left side menu.

  I have the following in the list:

  Orders

  Admin

  View profile

  It is a static so each link to a page of the list.

  However I want to have it so that when I click on the controls bind it then displays a dynamic list of the commands in the menu, then it should look like this,

  Orders

  Order 1

  Order 2

  Order 3

  Admin

  So I have a dynamic list that creates the list commands. How can I "attach" it in the static so that the parent is the link of orders in the static list?

  Thanks for your help.

  If none of the entries in the list are dynamic, then the entire list must be dynamic. See using lists/Navigation Menu to universal theme APEX5 for a similar scenario.

  Additional test cases

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.

• How to convert MS SQL Server 2008 Stored Procedures of Oracle 11 g SPs?

  We have an application from MS SQL Server 2008. We want to migrate to Oracle 11 g.
  
  What is the recommended Oracle method for
  (1) migration of data (Tables, triggers, sequences, views etc..)
  (2) the stored Procedure migration.
  
  What is the recommended tool or method pls?
  
  We have 100s of MS Sql Server stored procedures. Then, needing a tool or method. We can rewrite all of them from scratch.

  Hello

  Let me clarify some of the issues that you mention. But I advise you to get some professional help with migration because:

  1. you must understand the architectural differences between SQL Server and Oracle. They are of different databases.
  2. understand data type mappings.
  3. understand the complete migration process. Just using the OTN article as a migration guide won't help because it just shows how use SQL Developer to this task.
  4. understand that 100% of successful Oracle conversion is not possible with all the tools. There will always be gaps, gaps in functionality, bugs etc. So there will be some amount of manual work involved.
  5. There are many other tasks involved in the migration that cannot be accomplished with SQL Developer.

  Get now your questions:

  1. in 3.1, there is migration option for the "capture of database in offline mode". It is under the Tools option. So in 3.1 we do not have a separate tab, called "Migration."
  2. use 3.1 because it is much better than 2.1 in terms of capabilities.
  3 migration Wizard is the easiest way to migrate. Where are you getting confused?
  4 "column data" seems to be a stored procedure in SQL Server. If it is not there in the underlying table, why he uses in the SQL statement in the procedure then? I think that we have a problem of "reserved word" with the name of column "Data". Will have to check that.
  5 VARCHAR (@max) must be mapped to VARCHAR2 (4000) in Oracle. It may be a bug in SQL Developer. So during the mapping of data type in the migration wizard, you can change the default mappings.

• BPEL does not receive "return value" of MS SQL, stored procedure

  Hello
  
  We are facing this problem citing a MS SQL stored procedure the BPEL (jdbc 1.2 driver). We have created the wsdl for the stored procedure correctly using a command line utility tool provided with Oracle SOA Suite.
  But the question is THAT BPEL is not able to get the data present in the statement of "return" of the procedure. We receive null output. But it is able to extract the data from the output variable, if any. Case 1 below is for the return statement. Case 2 is for the output variable
  
  
  Case 1: in the following, the output is returned using the return statement. The BPEL that calls this procedure is to obtain a NULL value as an answer to this.
  
  
  ALTER PROCEDURE [dbo]. [AddNumbersRet]
  -Add the parameters for the procedure
  @Number1 int,
  @Number2 int
  AS
  BEGIN
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;
  
  -Controls insert for procedure here
  Return (@Number1 + @Number2);
  END
  
  Case 2: in the following, the output is returned using the SumOfNums output variable. The BPEL that calls this procedure is to obtain a correct answer.
  
  
  ALTER PROCEDURE [dbo]. [AddNumbers]
  @Number1 int,
  @Number2 int,
  @SumOfNums int output
  AS
  BEGIN
  
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;
  
  Set @SumOfNums = (@Number1 + @Number2);
  
  END
  
  
  
  Case 1 is a failure and case 2 is successful. We cannot change our procedures similar to case 1 to use variables of output because of dependencies on other applications.
  
  All the world is facing this problem? This looks like a bug in BPEL. Please, share your experiences.
  
  
  Thanks and greetings

  There is a gap in the command line utility that was addressed in the adapter configuration (AS11gR1) Wizard. The API is a procedure, not a function, so does not return the query for the parameters that the utility made anything for the RETURN statement.

  The adapter configuration wizard is unable to say if there is a RETURN statement either, but it provides the user with a check box that can be used to indicate the presence of the declaration. In the wizard, if you check the checkbox, a parameter is added to the XSD to the RETURN statement. In essence, the adapter will process the procedure as a function and you will get the value of the PERFORMANCE.

  Usually, I wish to indicate that you certainly should NOT change the generated XSD. But you might be able to do it, by adding the necessary element to the OutputParameters for your RETURN statement. Add the following immediately AFTER the element of 'Lines', which occurs first in the XSD and BEFORE all items for the other none.

  Use a value for the "" that is meaningful to you. The wizard uses the name of the stored procedure with the name of the element. We could call this "RETURN_VALUE" or else if is more to your liking. Add the item after you generate the XSD using the command line utility, and then use the XSD when you model your BPEL processes. The WSDL should already have the content for this element handling.
