• transaction isolation stored procedure-level testing

  Hello

  I want to study the concurrency in the Oracle database using stored procedures in pl/sql with different transaction isolation levels.

  The idea is to send to the database of a number "n" of simultaneous transactions where n can be {100, 200, 400, 1000} and for each isolation level (READ COMMITTED, SERIALIZABLE) to determine the number of transactions committed, how much data, run time incorrect.

  The question is how can I generate n transactions that run simultaneously on the data base and how to get these results. I understand that this task can be done as well by using pl/sql stored procedure in the database or inside a JSP Java web application. Advantages/disadvantages?

  I should mention that I'm a begginner in Oracle...

  Thank you in advance.

  You want to run a large number of asynchronous (parallel) transactions.

  Although this can be done by running the Oracle's work, I think it is easier to work with the client side, using a Java program (for example).

  It doesn't have to be a web application (for example. JSP), can be a client Java that uses Java threads, and each thread is using a single database connection (and the corresponding database session).

• How to use stored procedures of database instead of triggers in database?

  Hi gurus

  Here in SQL / PLSQL community discussion, I read some discussions that the stored procedures of database are better and 9should be used instead of database triggers.

  But despite reading 10s of discussions, I am unable to understand how a stored procedure may be an alternative to a DB-trigger while having many differences.

  And even if I'm using a DB instead of DB-trigger procedure, then at what level I should call? of my application, oracle forms IE?

  And should I write 3 different procedures, each of them for the Insert, update and delete while I can manage all of these events from a single trigger?

  Will you please advice me for this because I am using widely especially triggers to maintain the Stock / inventory, update several tables of a trigger n etc.

  PS... I'm working on the database 10g Rel.2.

  I use extensively since Oracle 7 database triggers (database Oracle 6 had no triggers).

  I use it mainly for complex integrity checks and sometimes for the calculation of derived data.

  So, I do not accept that "database triggers are evil".

  It is often said that, instead of triggers in database, we use the API (API function, better than the table API).

  However, the API may not always replace triggers.

  Excellent explanation is given by Toon Koppelaars in 'triggers considered harmful, considered harmful' http://harmfultriggers.blogspot.com/

  Regarding your question, it is possible to make the procedures of database to work with Forms - Yes, it is possible.

  You can make the database to INSERT, UPDATE, and DELETE procedures and call them before or / and after INSERT / UPDATE / DELETE triggers of forms.

  Another option is to use on INSERT / UPDATE / DELETE triggers of forms.

  Please note that I do not use these forms to work with the Oracle database triggers. In my view, database triggers are much better.

  The third variant will create a data block in a procedure that uses a "table of records.

• ODP 12 c version 3 with EF 6.1.1 I can't add Stored Procedure of a package to my model

  I use the ODP 12 c Release 3 (12.1.0.2.1), with Entity Framework 6.1.1 with the first database in MS Visual Studio 2013 update 4

  I have a MVC 5 (.Net Framework 4.5.2) project that connects to Oracle 11 G R2 Database server, an existing database (Tables, views and a pack of Stored procedures)

  I can add tables and use them successfully in my model
  I can add a simple stored procedure

  Here's the problem:
  I have my .edmx file right click and click on "update model from database...". «, on the 'Add' tab, I chose «Stored procedures and functions»
  I can see the list of procedures stored in the package (format packageName.usp) and check the box for the stored procedure of my package, then click 'Finish' to start the update process.

  No stored procedures have been added to my Model.Store

  
  The only possible exit I get the 'entity data model' is:
  Generated template file: Model1.edmx.
  Loading metadata from the database took 00:00:00.5803351.
  The model generation took 00:00:00.3761861.

  How to add a stored procedure from a package with the Entity Framework 6.1.1?

  I found the answer.

  When in the edmx model and you right click "Update Model database.

  Uncheck "Import selected stored procedures and functions in the entity model", select the package and update procedures. (It works)

  Then in "Model Explorer" under "Model. Store\ stored procedures/functions" you will see your procedures in the package (finally). Then their card in "Function Imports".

  I don't understand why unchecking import stored procedures works, but it does.

  I also found easier to simply call the procedure directly and not using Entity Framework, as all my procedures are: insertion, update and deletions and not all parameters mapped on the model for the view.

• Creation of XML report using the PL/SQL stored procedure

  Hi friends,

  I'm working on a report xml with the xml source as a PL/SQL stored procedure.

  I mean the fiscal year indicated in the following link to understand the process:

  http://orclapp.blogspot.com/2012/02/developing-xml-publisher-report-using.html

  In the example shown in the link above, I did not understand the following:

  (1) in the following procedure, setting out "retcode" is not used at all.

  What is the importance of this parameter.

  REPORT PROCEDURE (errbuf OUT VARCHAR2, retcode OUT VARCHAR2, p_product_id in NUMBERS)

  (2) after the xml data are prepared and updates 'l_result' variable Clob, what follows

  Loop is executed. I am not able to understand why the following loop is required.

  LOOP

  EXIT WHEN l_length = l_retrieved;

  IF (l_length - l_retrieved) < 32000

  THEN

  SELECT SUBSTR (l_result, l_retrieved + 1) IN l_xmlstr FROM DUAL;

  l_retrieved: = l_length;

  fnd_file.put_line (fnd_file.output, l_xmlstr);

  ON THE OTHER

  SELECT SUBSTR (l_result, l_retrieved + 1, l_offset)

  IN l_xmlstr

  FROM DUAL;

  l_retrieved: = l_retrieved + l_offset.

  fnd_file.put_line (fnd_file.output, l_xmlstr);

  END IF;

  END LOOP;

  (3) in the example it is not explained how the concurrent program gets the xml data?

  I guess that it is written to a file by using the following line of code:

  fnd_file.put_line (fnd_file.output, l_xmlstr);

  I would be grateful if someone can shed some light in my questions above so that I can well understand the process.

  Thanks and greetings

  Hi 32000 in the code is a 'safe' than 32767 available max mesh, loops is intended to get around the entire thing into pieces that can be managed within the limits of the data type.

  BTW; If you are in the following Oracle e-business, you can also use the Oracle reports very simply to create the XML output.

  If you have reports developer all you need to do is put raw sql (create XML without any "Fireworks") in the SQL report and then set reporting in XML format in the definition of program in Oracle e-business.

  SQL Loader to load data from Oracle

  Export/import (if you really mean the Oracle exp/imp orders) would be used to export and import from a database to a different Oracle database Oracle, if you say it's on DB2, so I don't know how you did that.

  Your question is always crazy.

  We do not know how you took procedures of DB2 and converted to procedures on Oracle.

  As Frank says, there will certainly be performance factors, so you can just take the code of a database, write the same code on Oracle in the same style and expect it to work as well.   The correct way to migrate the code must understand what each unit of code is supposed to do (entered accept, what exit that generate, what he does on the basis of data etc.) and write from scratch in Oracle uses the best features of Oracle for this.

  In regard to the performance of SQL queries, if database tables were well designed for their use (i.e. properly normalized (assuming that it is not an OLAP database)) and appropriate indexes exist for queries that will be made against it and statistical database etc are collected then Oracle will choose the best path of execution by SQL executed against them.

  So is your question about the performance of SQL queries on the database tables or code PL procedure/functions that were converted from DB2 to Oracle; and if the latter, then it would need to know which deal with these procedures/functions through to become Oracle'ized, and what looks like him code PL (i.e. don't talk about code that has loads of nested loops cursor rather than the SQL instructions pure; or code that did a lot of "off-database" calcuations or other).

  There is no way that anyone can just give you a list of the "impact", and how you say it is easy to set up the database once you know the implications is somewhat flippant.

  Hello

  I know it's a pain to post CREATE TABLE and INSERT statements for the sample data.  Think about why it is necessary: that people who want to help you can recreate the problem and test their ideas.  If you post statements that do not work, which does not recreate the problem or to test their ideas.  Test (and, if necessary, correct) your statements before committing.  Make sure all quotes are balanced.

  I don't understand the desired output.  For example, when n_emp = 'Juan', why is-employees_ofthe_boss = 6, 5 no?  When n_emp is 'Angelic', why is-salary_increase = 45, not 30?  When n_emp = 'Alberto', why is-salary_increase = 5, not 3.5?

  You may want something like this:

  WITH universe_dup AS

  (

  SELECT i_emp, n_emp, q_sueldo, i_jefe

  SYS_CONNECT_BY_PATH (i_emp, ","). ',' AS line

  ,       LEVEL                                    AS lvl

  Of empleado

  START WITH (IN) i_depto

  SELECT i_depto

  OF Department

  WHERE e_depto = 'Finance' - or what you want

  )

  CONNECT BY i_jefe = PRIOR i_emp

  )

  universe

  (

  SELECT i_emp, n_emp, q_sueldo, i_jefe

  MAX (lineage) DUNGEON (DENSE_RANK LAST ORDER BY lvl) AS lineage

  MIN AS min_level (lvl)

  Of universe_dup

  GROUP of i_emp, n_emp, q_sueldo, i_jefe

  )

  got_salary_increase AS

  (

  SELECT a.i_emp, a.n_emp, a.i_jefe, a.min_level

  EARL of (d.i_emp) AS employee_cnt

  , a.q_sueldo * CASE

  WHEN COUNT (d.i_emp) > = 3 PUIS.2

  WHEN COUNT (d.i_emp) = 2 PUIS.1

  OF AUTRE.05

  END AS salary_increase

  OF the universe a

  LEFT OUTER JOIN universe d ON d.lineage LIKE '%', | a.i_emp | ',%'

  AND d.i_emp <> a.i_emp

  GROUP OF a.i_emp, a.n_emp, a.i_jefe, a.min_level, a.q_sueldo

  )

  SELECT p.n_emp AS boss

  p.employee_cnt AS employees_ofthe_boss

  p.salary_increase AS salary_increase_boss

  c.n_emp AS employees_name

  , NVL (c.employee_cnt, 0) AS employees_ofthe_employee

  , NVL (c.salary_increase, 0) AS salary_increase_employee

  OF got_salary_increase P

  LEFT OUTER JOIN got_salary_increase c ON c.i_jefe = p.i_emp

  WHERE p.min_level = 1

  ;

  Depending on your data and your needs, it may be more effective to do "START WITH i_jefe IS NULL", as one of the above.  I guess "START WITH i_depto (...)" in the largest tables, when efficiency is more important.

• setting report parameters fails for the report that runs the stored procedure in QMR FDM 2.1.1

  Hello

  Can someone help us please on this issue we have; If a solution is already available somewhere on the forum please link me to it.

  Please see our situation;

  The script below was part of the customization of a colleague to a script of Oracle FDM ("AftFileImport").

  There are no screenshots at this stage that came back to us with a temporary workaround.

  More detailed description:

  We built a custom report of FDM ("FSBValidationErrorsforAllLocations") that accepts two parameters (CatKey, period) and which calls a procedure stored in SQL Server with the same two parameters. FDM SQL statement of the report is:

  RUN FSBValidationErrorsforAllLocations ' ~ time ~', ~ Cat Key ~

  It works through the User Interface.

  When you try to put the two settings by customizing the event Oracle 'AftFileImport'script, the report fails. Below the part of the code in the 'AftFileImport', where we tried to fill values:

  • objReport.mParametersClear
  • objReport.mParametersAddNew "CatKey", RES. PstrCat
  • objReport.mParametersAddNew 'Period', RES. PstrPer

  We must understand why the way above to the definition of the parameters does not work with stored procedures, as seems to be the only documented way Oracle of setting parameters.

  Please let me know if that's enough.

  
  

  Thank you in advance.
  

  Hello

  which is the error when you run the script?

  • objReport.mParametersAddNew "Cat Key", RES. PstrCat

  Try again with the white space as it is how you named your parameter in the report definition, didn t you?

  Also try to use the built like the following examples:

  	objRP.mParametersClear
  	objRP.mParametersAddNew 'Period', CDate (dtePeriod)
  	objRP.mParametersAddNew 'Loc', CLng (lngLocation)
  	objRP.mParametersAddNew 'CatKey", CLng (lngCatKey)
  	objRP.mParametersAddNew "TargAcct", CStr (strAutoMapAcct)

• 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:

• Link to database not be created using a stored procedure

  Hello

  I am creating a link of database using a stored procedure.

  Here is the code for it

  CREATE OR REPLACE PROCEDURE create_db_link (ca_db_name IN VARCHAR2,

  ca_service_name IN VARCHAR2)

  AUTHID CURRENT_USER IS

  BEGIN

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ca_db_name identified by ca_db_name using "ca_service_name" ';

  Could you please help me understand why it shows the parameter names in the name column of the USER and the HOST instead of the name of the database and the name of the service?

  This is to show exactly what you said to do.

  Did you expect that Oracle would read as if by magic through your string you passed to run immediately and magically know to replace all occurrences of the string that correspond to local (or even global) parameter/variable names with the values of these variables?  It does not work like that.  You could concatenate the values into the string.

  for example

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ' | ca_db_name |' identified by ' | ca_db_name: ' using the "' | ca_service_name | " ' ;

  But why are create you database links running?  Shouldn't this be part of the design of your application and the initial fact before the application runs?

• Procedure stored procedure of Vs

  Hello all;

  I'm getting confused with the stored procedure Vs.

  Please say that is valid?

  Procedure is a PL/SQL code block, it never stored in the database.

  Procedure is a PL/SQL code block, it is named and stored in the database.

  Stored procedure is block of PL/SQL code is named and stored in the database.

  s someone saying the basics of Oracle PL/SQL procedure . Microsoft SQL Server stored procedure notion.

  
  

  Thank you all;

  
  

  
  

  
  

  
  

  Hello

  I don't know what you mean by "a PL/SQL block that is stored in the database without a name".  All that is stored in the database has a name.  Objects in PL/SQL (procedures, functions, triggers, or packets) may contain blocks without name, but those without name of blocks are not procedures.

  A procedure is in fact a PL/SQL block that is stored in the database with a name.  So is a function.  So is a trigger.

  Etbin has a good point (as usual): it is difficult to give a good answer to questions short and vague without any context.  If you can do your details of more detailed questions, we could have better QA idea of what you want to know.  For example, if you don't understand something that read you in a blog or a book, publish the entire paragraph that contains the part don't understand, as a link or make reference to the work complete you.

• Call to the stored procedure parameter passing script

  Hello

  I have a database on linux server. On the same server, there is a shell script which takes 3 parameters.

  Now I want to do a procedure (stored procedure) that will have 3 parameters pass and run this script with these settings.

  I had created object directory pointing to the correct directory granted all privileges on it (I hope).

  Now, I wondered how the code of procedure?

  I also did a program within the database which takes 3 parameters, but I don't know how to operate it. I don't know if I can use work to run the program, because

  It is a multi user thing and I think that this will not work as expected if 2 or more users run it.

  In any case, I was hoping that I can solve this problem by creating the procedure that will run the script that is provided with 3 parameters, that I need.

  I hope I'm clear on what I want to do.

  Please if you have an idea how to Edifier post your ideas.

  Thank you!

  Hello

  first I want to thank you for the reply.

  option 1... I don't want not to use java or c because I have no skills in programming languages.

  option 2 you mentioned dbms_scheduler.

  If I understand the procedure should go like that.

  I create whitin database program. Then I create a job which runs this program. And whenever I want to run my shell script, I'll do the work.

  WHA happen if 2 different users will want to run the script at the same time?

  Thank you for your response.

• 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.

• View Vs stored procedure

  With the help of Oracle 11 g
  Front End .NET
  
  To display the data on the front end, we must query the DB tables and display. In this case, that is the best solution - views or procedures stored?

  1 b says:
  Is it okay that mantra?
  SQL > PL/SQL > C > JAVA
  and the view's SQL only, so it is better for performance reasons? TX

  Yes. But the mantra in this case means not PL/SQL allows to read the rows in the view, copy (fetch) in a collection (residing in the expensive PGA in memory) and who returns to the caller.

  It is false and so horribly.

  The right approach would be for the appellant NOT to use the view.

  Why? Because the appellant (program and app developer) need to understand the data model, need to understand SQL Oracle and the concepts of performance and so on.

  If the data model or the view changes - the app program should also be updated.

  This is why the use of a PL/SQL procedure is preferable. He resides in the database. (I hope), it is written by experienced database developers. The procedure can be modified to support the new features and changes to the data model, without having to touch a single line of code in the app program.

  All the procedure has to do is accept the call by the app program, decide how to build the SQL (on the view/table/whatever) for the caller, create a SQL Server Shared pool cursor and then return the handle of the cursor (using a ref cursor data type) to the appellant.

  Instead of the source of passage calling SQL for Oracle and get a cursor handle, the appellant seeks, so a PL/SQL procedure that returns the SQL cursor handle.

  The app program is now abstract concepts and database layer techniques Oracle and SQL, recursive SQL, analytical Oracle performance, Oracle CBO advice and so on. The PL/SQL procedure takes care of all this.

  This is why using a PL/SQL stored procedure would be a better choice that the client application dealing with the language of Oracle SQL and Oracle (such a view) in the database objects.

• 'ALL' to a stored procedure in Oracle 10 g

  Hello
  
  I have a stored procedure that takes the parameters from a report. I have two settings with a list of things in both entities.
  
  Now, in the two settings, I have the word "ANYTHING" to pass to the stored procedure to indicate that all elements in the list of parameters should be consumed.
  
  I kinow what should be in the WHERE clause, but have no idea how to do this in Oracle. This pseudo code below to get an idea of what I'm trying to accomplish here;
  
  IF Parameter1 = "ALL".
  then
  Field1 = (select * from table1) other end parameter1 = Field1
  
  IF Parameter2 = "ALL".
  then
  Field2 = (select * from table2) other Field2 = parameter end 2
  
  
  Any help would be Apprecited guys!
  
  Thank you

  Hey, Manny,

  I'm not sure that understand the question.
  I think you want something like this query on the table scott.emp:

  VARIABLE  target_deptno  VARCHAR2 (5)
  VARIABLE  target_job      VARCHAR2 (10)
  EXEC     :target_deptno      := 'ALL';
  EXEC      :target_job      := 'CLERK';
  
  SELECT  ename
  ,     deptno
  ,     job
  FROM     scott.emp
  WHERE     (     :target_deptno     = TO_CHAR (deptno)
       OR     :target_deptno     = 'ALL'
       )
  AND     (     :target_job     = job
       OR     :target_job      = 'ALL'
       )
  ;
  

  Output (with the settings as shown):

  ENAME          DEPTNO JOB
  ---------- ---------- ---------
  SMITH              20 CLERK
  ADAMS              20 CLERK
  JAMES              30 CLERK
  MILLER             10 CLERK
  

  Try it with different values for the parameters. If either of the parameters is 'EVERYTHING', then all values (and NULL) in this column are in agreement.

  In special cases (for example, if you know that deptno cannot be NULL) there is a little more simple ways to get the same results.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data. Given that this problem concerns the parameters, give a few sets of parameters and the results you want from the same sample for each game data.
  If you can show the problem using commonly available (such as in the diagrams of scott or HR) tables, then you need not display the sample data; After the desired effect and the explanation.
  Always tell what version of Oracle you are using.
