• Creating views, dynamic SQL within stored procedure

  I'm having a problem with the creation of dynamic views of in a stored procedure. The following declare block works fine:
  
  DECLARE
  parameter i_nom_table varchar2 (200): = 'abc ';
  xyz cursor script, SELECT step
  STARTING from scripts
  WHERE table_name = i_nom_table parameter
  ORDER BY step CAD;
  l_sql scripts.script%TYPE;
  l_step scripts.step%TYPE;
  l_error VARCHAR2 (200);
  l_code VARCHAR2 (200);
  Start
  XYZ OPEN;
  LOOP
  XYZ-FETCH INTO l_step, l_sql;
  OUTPUT WHEN xyz % NOTFOUND;
  immediately run l_sql;
  insert into ingest_log values (null, sysdate, i_nom_table, l_step, l_sql, 'Success' parameter);
  END LOOP;
  CLOSE XYZ;
  insert into ingest_log values (null, sysdate, parameter i_nom_table, 0, "Accomplished all the steps.", "Success");
  EXCEPTION WHEN OTHERS THEN
  l_error: = substr (SQLERRM, 1, 200);
  l_code: = SQLCODE;
  insert into ingest_log values (null, sysdate, parameter i_nom_table, l_step, l_sql, l_code |) ' - ERROR - ' | l_error);
  END;
  
  However, if I create a procedure with this block and try to run it I get an insufficient privileges error. Do not know why. All tables, views, procedures are under the same user, and the user that I'm connected as the runtime of the declare block. The user has the following privileges:
  
  Connect, resource, xdbadmin, s/n

• How to query the DDL lock functions or stored procedures and packages?

  Hello!
  
  The subject says it all: how to display existing DDL locks on the functions or stored procedures and packages?
  
  While running a procedure, it cannot be deleted or replaced, so there must be a DDL lock on it. The information does not seem to be in V$ LOCK or V$ LOCKED_OBJECTS.
  
  Thank you!

• 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:

• Difference between function and stored procedure

  Hi guys, I don't understand the exact difference between a function and a stored procedure. I have a lot of google but still. Can someone explain in simple terms. Thank you.

  Hello

  Here is an example of a user-defined function:

  CREATE OR REPLACE FUNCTION     factorial
  (      in_num       IN     PLS_INTEGER
  )
  RETURN     PLS_INTEGER
  DETERMINISTIC
  IS
  BEGIN
       IF  in_num IS NULL
       THEN
            RETURN     NULL;
       ELSIF in_num <= 1
       THEN
            RETURN  1;
       ELSE
            RETURN  in_num * factorial (in_num - 1);
       END IF;
  END     factorial;
  /
  SHOW ERRORS
  

  This function returns an integer. You can use the function (or, more exactly, the integer returned) everywhere where a whole expression is allowed.
  For example

  SELECT     ROWNUM
  ,     factorial (ROWNUM)     AS f
  ,     loc
  ,     SUBSTR ( loc
              , 1
              , factorial (ROWNUM)
              )          AS s
  FROM     scott.dept;
  

  Output:

  `   ROWNUM          F LOC           S

• Function of stored procedure defined by the user of the appellant

  Hi all -
  
  I am trying to call a function defined by the user of a stored procedure. I'm using something like
  

        IF condition1 THEN
             function1(param1, param2);
       END IF;

  the above is correct.
  
  I have PLS-00221 function1 is not a stored procedure or is not defined?

  Well, if it is a function, you will need to assign its result value in a variable.

  Like this:

  DECLARE some_variable [of the right datatype];
  ...
   IF condition1 THEN
          some_variable := function1(param1, param2);
   END IF;

  Hello

  I think I know what is the cause of the problem.

  There is a bug in version 4.1 where different types of objects (including functions and stored procedures) do not appear in the tree view to compare if the property "include physical properties to compare the feature ' is not defined.

  So the solution is to ensure that this property is set.  It is on the Data Modeler > DOF > DDL/comparison of preferences page.

• Required privilege to view the source code for the stored procedure

  RDBMS Version: 11.2.0.4

  Platform: Oracle Linux 6.4

  In our Production database, we have an application schema named CRM_PROD. And we have a read-only user named steve in this PB.

  Steve must be able to view the source code of all stored procedures, functions and packages in the CRM_PROD schema. But steve shouldn't be able to run these procedures, functions and packages in the CRM_PROD schema. What a privilege should give Steve for this?

  SYS is owner of the dictionary of data and tables for the source code. See configuration of privilege and role authorization - 11 g Release 2 (11.2).

  Select it no matter what dictionary grant will give user (read) access to the full data dictionary.

• would you use a stored procedure or a function

  Hello
  
  I have a very long query. I reduced a large number of sections of it with views.
  
  But now I have a section that is repeated several times, about 40 times. It is about 15 lines of SQL code.
  
  The variation between these blocks are two fields which change their value and I always join the result of these blocks using the same ID.
  
  Of course, I think I can extract in a central block (DRY) and call them from a main request, the question is how.
  
  My first approach would be a stored procedure. But all the examples I found that you use some PL/SQL or Java, that I could also... but isn't it overkill?
  The function?
  Any recommendation?
  
  Thank you!

• Call of function/stored procedure of dashboards

  Hi all
  
  My requirement is to call a stored procedure /function of dashboard and display the result in the dashboard.
  
  I created a function that takes in 2 dates and restores the lines in this date range
  
  (1) creation of function
  
  create or replace FUNCTION FUNC3 (BDATE TIMESTAMP, EDATE TIMESTAMP) return as sys_refcursor
  R1 sys_refcursor;
  BEGIN open for r1
  SELECT * FROM EMP WHERE HIREDATE BETWEEN BDATE AND EDATE.
  Return (R1);
  END;
  
  
  (2) created a dashboard quickly start date and the end date and the variable defined as variable presentation 'Pre_B1Date' & 'Pre_E1Date '.
  
  (3) created a request directly to the database as
  
  SELECT FUNC3 (to_date (' @{Pre_B1Date} ',' YYYY/MM/DD hh: mi PM'), to_date (' @{Pre_B1Date} ',' YYYY/MM/DD hh: mi PM')) FROM DUAL
  
  (4) that I've created a dashboard with the above command prompt & demand live, but when I try to open the dashboard why the BI server is blocking down.
  
  gave me an error

  have one never faced this problem?
  
  or is there another way to call a funcation stored dashboards, /procedure
  where you can pass the variables of the presentation and view the output put this /procedure function
  
  Thank you
  sangov

  Yes.

  You can't return a cursor in a column in a select statement. You must use a piplined function (also known as table function).
  http://gerardnico.com/wiki/language/PLSQL/plsql_pipelined_function

  You'll find yourself with:

  select * from FUNC3(BDATE,EDATE)

• Create a stored procedure in the settings view

  I want to be able to create a view with the parameters of a stored procedure.

  Oracle 11g.

  don't know how to use the variable in immediate execution.

  CREATE OR REPLACE

  PROCEDURE TEST_GENERIC (TBL IN VARCHAR2, VWNAME IN VARCHAR2)

  AS

  BEGIN

  RUN IMMEDIATELY "CREATE OR REPLACE VIEW VWNAME AS SELECT SYSDATE FROM TBL";

  COMMIT;

  END;

  exec ('BIRD', 'DUAL') TEST_GENERIC

  Thanks for any help

  Hello

  Single quotes enclose a literal string; in other words, the text between the quotes literally means what it says, without reference to any variables.

  So, when you say:

  RUN IMMEDIATELY "CREATE OR REPLACE VIEW VWNAME AS SELECT SYSDATE FROM TBL";

  CREATE the word literally means to CREATE.  You may or may not have also a variable called CREATE, but that is irrelevant.

  The word OR means OR literally.  You may or may not have also a variable called operation GOLD, but that is irrelevant.

  REPLACE the word literally means REPLACE.  You may or may not have also a variable called to REPLACE, but that is irrelevant.

  ...

  The TBL Word literally means TBL.  You may or may not have also a variable called TBL, but that is irrelevant.

  If you want to reference a variable called TBL, then use TBL outside single quotes, like this:

  ...

  sql_text: = "CREATE or REPLACE VIEW VWNAME AS SELECT SYSDATE FROM '

  ||  TBL;

  dbms_output.put_line (sql_text |) "= sql_text before EXECUTE IMMEDIATE');   -For debugging

  EXECUTE IMMEDIATE sql_text.

  ...

  On the rare occasions when you use dynamic SQL statements, always put the dynamic SQL statement in a string variable (for example, sql_text, above) so that you can easily display for debugging purposes and to ensure that the command you are viewing is the same exact command that you should run.

  I guess the code you posted is a first test version of something that will be much, much different when it is finished.  Creating objects from database (such as views) in PL/SQL is almost always a terrible idea, and it seems that opinion that this code is attempting to produce would be very useful, anyway.

• 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.

• Simple question-how to call a stored procedure or function of apex?

  Simple question-how to call a stored procedure or function of apex?
  Thanks advance.
  Doug

  Hi Doug,.
  You can call a procedure or function of apex. It depends on what you want to do with the function or procedure. If you want to retrieve table data in a specific area, you can try something like this-

  The following statement creates the function get_bal on the oe.orders of sample table (PL/SQL is in italics):

  CREATE FUNCTION get_bal (acc_no in NUMBER)
  RETURN NUMBER
  IS acc_bal NUMBER (11.2);
  BEGIN
  SELECT order_total
  IN acc_bal
  Orders
  WHERE customer_id = acc_no;
  Return (acc_bal);
  END;
  /

  The function created in the previous example can be used in a SQL statement. For example:

  SELECT get_bal (165) FROM DUAL;

  GET_BAL (165)
  ------------
