• How to perform procedures with REF CURSOR & PLSQL settings table in SQL Dev?

  I have 3 SQL Developer. I create a procedure with a set of tables/PL/SQL as an input parameter and a SYS_REFCURSOR as output parameter.
  
  When I press the green arrow (Run button) block the dialog box run PL/SQL PL/SQL has no place at the PL/SQL table with records of entry and also to see the output of the SYS_REFCURSOR.
  
  I get the error ORA-06550 and many other errors when I run the present.
  
  How to do this please?

  In the debug code, lose the ABS. Prefix the SYS_REFCURSOR QC_SQL_DEVELOPER_TEST.
  Also, do not use same name of your settings on your bind variable (so e.g.: OUT_REF_CURSOR).
  REF CURSOR is supported output types, so you will get the output of their share in the output tab.
  However the output system does not recognize your own types as your PL/SQL table. You need to write an exit procedure yourself, indexing correctly, using the DBMS_OUTPUT.

• Report regions - use of the Ref Cursor?

  APEX 4.2

  See http://mikesmithers.wordpress.com/2012/02/22/getting-apex-to-play-with-ref-cursors

  The above article is older than 2 years. The techniques shown in the link above still valid today if we want to create a report region in the APEX are based on a function that returns a Ref Cursor? Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  If the function returns the ref cursor is the only point of access that you have data then Yes, it probably is. If you have direct access to the underlying database objects and the function does not have something very complicated, then you are probably better off creating your own body of the function returning SQL query data source.

  Everything about the dynamics of ref Cursor now I divided in 2 layers, with a function for generating the dynamic SQL and another for bind parameters open the ref cursor. APEX apps can then reuse the functions of SQL query in function body return SQL query data sources (if you take a bit of care to keep the bind variable names vaguely APEX-point-friendly).

  Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  See this for the technical background on why APEX is not yet support ref Cursor and this for more information of the Oracle team on the possibility of future support. Obviously, he did not he in 4.1. I suspect that data REF CURSOR region sources depended on a minimum requirement of DB of the 11.1.0.6 (where was introduced support for the conversion of the REF CURSOR in the cursors DBMS_SQL). As minimum DB for APEX 5.0 version is 11.1.0.7, it would be a possible feature for 5.0, but it is not classified as one.

• Create a REF CURSOR as an array of display/temp

  Hello world

  I had to upgrade a number of Crystal Reports Using REF CURSOR as part of an ERP upgrade project. The new version of the ERP application supports more use of the REF CURSOR and only supports the use of views/tables.

  I don't see how I can rewrite the REF CURSOR (which are defined in the PL/SQL procedures), in the form of VIEWS / TEMP TABLES with a single call. That is to say when the user runs the report.

  Can anyone suggest a method of conversion of the REF CURSOR in view/Temp Table without the two steps, the steps to populate a temporary table and then, i.e. 1 - 2 - query the table in the report. ??? -I was looking at a Pipelining as an option but again could reach with only two stages, pre filling before running the report.

  Any advice would be greatly received.

  Kind regards

  David.

  I found a solution by creating a FUNCTION with a PIPELINED return cursor, and then create a temporary table in the result set. Not really ideal was to use a Pragma AUTONOMOUS_TRANSACTION, but will work for me.

  Thank you

  I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.
  
  Please answer...

  Can someone give me an example of a scenario where we need to create a form manually based on a stored database procedure.

  In general, you will use a block of proceedings based when you have a collection of data from several tables presented in a form and your username must be able to update the information displayed.

  In your sample code, looks like you are using Oracle Support document "Melting a block on a Stored Procedure - examples of Code [ID 66887.1]". If this is the case, continue to follow the document - it guides you through all the steps. There is no need to manually configure things that the data block Wizard will work for you!

  I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.

  Why? Let the wizard block configuration data of your block based on a procedure for you. There is no need to manually browse the data! I did what you're trying, and it's more work needed. Leave forms to do the work for you. :)

  If you absolutely have to do things manually, I recommend that you use the PROCEDURE bonus_query (bonus_data IN OUT bontab) instead of bonus_refcur (bonus_data IN OUT b_cursor) . Then, in your code create a variable of type BONTAB, and then call the bonus_query procedure. Then, it's a simple case of a loop in the table of records returned by the bonus_query procedure. For example:

  DECLARE
     t_bonus    bonus_pkb.bontab;
  BEGIN
     bonus_pkg.bonus_query(t_bonus);
  
     FOR i in 1 .. t_bonus.count LOOP
        :YOUR_BLOCK.EMPLOYEE_NUMBER := t_bonus(i).empno;
        :YOUR_BLOCK.EMPLOYEE_NAME := t_bonus(i).ename;
        :YOUR_BLOCK.EMPLOYEE_JOB := t_bonus(i).job;
        :YOUR_BLOCK.EMPLOYEE_SALARY := t_bonus(i).sal;
        :YOUR_BLOCK.EMPLOYEE_COMMISSION := t_bonus(i).comm;
     END LOOP;
  END;
  

  This code example shows the basics, but as is the sample code - you will need to adapt to your situation.

  Also, I highly recommend that you look at the article inol listed. It is a very thorough debate on the REF CURSOR. If you have set up using a procedure based on the data source - it is more effective to spend the record table to your form that it must pass a ref cursor Using a ref cursor, you might as well just using a standard called cursor and loops on your named cursor. The effect is the same (a line returned at the same time creating lots of network traffic). Using the table of records is more efficient because the data set is returned if the network traffic is reduced.

  Hope this helps,

  Then, you use the wrong cursor and you performance degradation because the cursor returns data that is not required.

  We can extract a particular of ref cursor column, please suggest me

  You can not.

  Workaround would be to copy the handle of the cursor ref to a handle to the cursor DBMS_SQL and then use cursor DBMS_SQL to treat the projection of SQL. But it would be an ugly hack.

  The right approach would be to correctly use the SQL cursors in PL/SQL. And no, ref Cursor in PL/SQL (created by code PL/SQL to PL/SQL code) is almost always the WRONG choice.

  There are better native cursor data types in PL/SQL in particular supported cursors created by PL/SQL and PL/SQL.

  REF CURSOR is provided mainly as the cursors created by PL/SQL for an external client. There are very few reasons to create Ref cursors to use PL/SQL code.

• Recovery of the records by using the Ref Cursor or indexes per Table (which is better)

  Hi all
  
  I am interested to know if there is a performance (or other) advantages to return a result set from an Oracle stored procedure for a client application (for example, in Java) by using a Ref Cursor or Index by Table, respectively. Most of the people I met who know Java seem to use a Ref Cursor but did not say why this method is preferable. I'm not too familiar with Java and do not have the opportunity to test the difference between either method, but I am very interested in the other user forum about this view, gauging

  Hi zerathul,

  Thanks for the quick and helpful response. A REF CURSOR would be the best solution if the same set of results (content and number of records returned) should be dealt with by the application of the 'customer '. I'm guessing that maybe in this situation 'theoretical' that there might be less network traffic to return the set of results through an associative array,

  Kind regards

  Kevin.

  Yes, it would always be the best solution, because an associative array would mean collecting all the data in memory of expensive PGA on the database server before they pass any return on the network, while a fair Ref cursor is to feed the data over the network (maybe a little extra load, but you were unlikely to notice). Also the client application would treat a ref as of rows returned cursor data recovery and could treat them upon their arrival, an associative array is a collection of data which will then be entirely spent before any treatment could be done and then the treatment should go through the entire table to do.

  REF CURSOR will also provide other information such as the error codes etc regarding SQL if necessary. If you get an error when filling a table on the side of the database, it is not so easy to recover this error to the client.

  REF CURSOR is designed for this purpose. Use them.

• REF CURSOR in DB

• Call a procedure stored via JDBC with a REF CURSOR * input variable.

  Hello
  
  S/n of my client has provided me with a stored procedure that I need to call to get information about products prices. Something along the lines of:
  
  some_package.getPrices (products IN OUT csr_type);
  
  where csr_type represents a REF CURSOR. This cursor has a product ID column and a price column. The plan is to move the cursor with the populated product id column and have the routine decorate the slider with the prices.
  
  The setting in this plan is that it seems that it is not possible to go from JDBC REF CURSOR in . However, I'm not sure, since I can only find throw comments on various forums (e.g. http://www.orafaq.com/forum/t/35088/0/), without any reference. If I go back to the client and tell them that their idea will not work, I prefer to be able to point them to a documentation somewhere
  
  So I guess my questions are:
  
  1. it is indeed impossible to pass a REF CURSOR type as a variable input on JDBC to a stored procedure?
  
  2. is there information I can do about my client?
  
  3. am I on the right track thinking I need to go down the path of an array of objects?
  
  Thank you very much to anyone who can help
  Peter Svehla.

  Hi Peter,.

  I see it, missed that you actually want to pass in a list of products. Don't think that you can do this with the current procedure. A slider is just a pointer to a result set.
  How the result set is created and what it looks like, is determined when the cursor is opened.

  What does this procedure with the cursor? -It does not have some OPEN TO ; inside?

  Or, perhaps, you are supposed to send in an open cursor (does not much sense to me)?

  I have create a ref cursor query in reports 10 g. But it is giving error REP-0737: must be a function of return type 'ref cursor.

  Here is my code

  function QR_1RefCurDS return sys_refcursor is

  fate of the screen.

  

  Oracle Forms/Reports has a complete PL/SQL engine and (only) the SQL parser.

  However, the engine of forms/States PL / SQL and SQL Analyzer are at a level that was in the Oracle 8.0 database.

  So, in the forms/States functions/procedures and forms/States triggers, you can not use SQL commands that did not exist in the 8.0 database.

  The predefined SYS_REFCURSOR type is introduced in Oracle 9i.

  Use this:

  PACKAGE test_rc IS

  TYPE of rc_type IS REF CURSOR RETURN emp % ROWTYPE;

  END;

  FUNCTION RETURN QR_1RefCurDS Test_rc.rc_type IS

  test_rc.rc_type RC;

• Ref Cursor

  Hi guys,.

  You can develop the ref cursor please. I'm new to the plsql...

  Hi Alex,

  Introduction to the REF CURSOR

  With the help of REF CURSOR s is one of the most powerful, flexible and scalable means to return the query results to an Oracle database to a client application.

  A REF CURSOR is a PL/SQL data type whose value is the memory address of a workspace of query on the database. In essence, a REF CURSOR is a pointer or a handle to a game on the database of results. REF CURSOR s are represented by the OracleRefCursor class ODP.NET.

  REFCURSORs have the following characteristics:

  • A REF CURSOR refers to a memory on the database address. Therefore, the client must be connected to the database during the lifetime of the REF CURSOR to access.
  • A REF CURSOR involves a round-trip of additional database. While the REF CURSOR is returned to the customer, the actual data is not returned until the customer open it REF CURSOR and requests the data. Note that the data are not be retrieved until the user tries to read it.
  • A REF CURSOR is not editable. The result set represented by the REF CURSOR is read-only. You cannot update the database using a REF CURSOR .
  • A REF CURSOR is not back with scroll. The data represented by the REF CURSOR is only accessible in a way before and in series. You cannot position a record pointer inside the REF CURSOR to point to records in the result set.
  • A REF CURSOR is a PL/SQL data type. You create and return a REF CURSOR within a block of PL/SQL code.

  See this link which explained on cursor by Zerathul ref: PL/SQL 101: understanding Ref Cursor

  Kind regards
