• How to get the query of the region "PL/SQL function body returns the query string"?

  Hello
  
  is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?
  
  I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like
  
  < pre > v_return_query: = «...» » ;
  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.
  
  Kind regards

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

• Dynamic region of the body of the function return query did not work

  APEX 4.1

  Oracle 11g

  I have a report of dynamic fields according to the value of the different type of zone set element is body of pl/sql function, return query, see the source code of the region below.

  declare

  v_sql varchar2 (2000);

  Start

  IF: P2_BY = 'MONTH' THEN

  v_sql: = 'SELECT ' | : P2_TYPE | ', SUM (JAN) JAN, SUM (FEB) FEB, SUM (MAR) MAR, SUM (APR) APR, SUM (MAY) MAY, SUM (JUN) JUN, SUM (JUL) JUL, SUM (AUG) AUG, SUM (SEP) SEP, SUM (OCT) OCT, SUM (NOV) NOV, SUM (DEC) DEC OF THE RPT_HOTEL GROUP BY ' | : P2_TYPE;

  Return v_sql;

  end;

  But "Missing expression" error when Save source in the region.

  I checked the sql statement is valid in the sql command, and: P2_TYPE get the correct value.

  If the generic column name 'use' then get the correct report, but the column name is random.

  Please help solve.

  Thank you so mcuh

  Hi fac586,

  I couldn't thank you more. Of course, read you my code and found that the design of table is not reasonable. in fact I just design for the demonstration of the prototype, so do not consider architecture.

  I mean, it is that the problem has disappeared when I create a new page like this one, don't know how it happened. in any case what I need has been achieved, thank you very much for what you have done.

  Here I paste my code for reference, that someone might need.

  declare
  v_sql varchar2(2000);
  v_time varchar2(50);
  v_for varchar2(30);
  begin
  IF :P4_TIME='MONTH' THEN
  v_time := 'to_char(lodging_date,''MM'') MONTH';
  v_for := 'to_char(lodging_date,''MM'')';
  ELSE
  v_time := 'to_char(lodging_date,''YYYY'') YEAR';
  v_for := 'to_char(lodging_date,''YYYY'')';
  END IF;
  IF :P4_MEASURE='NIGHTS' THEN
  v_sql := 'SELECT * from (SELECT ' || :P4_BY || ',VENDOR_NAME,' || v_time
  || ',count(entry_legacy_key) ROOM_NIGHTS
  FROM HOTEL_EXPENSE GROUP BY ' || :P4_BY || ',VENDOR_NAME,' || v_for || ')
  PIVOT (SUM(ROOM_NIGHTS) FOR ';
  ELSE
  v_sql := 'SELECT * from (SELECT ' || :P4_BY || ',VENDOR_NAME,' || v_time
  || ',SUM(APPROVED_AMOUNT) SPENDING
  FROM HOTEL_EXPENSE GROUP BY ' || :P4_BY || ',VENDOR_NAME,' || v_for || ')
  PIVOT (SUM(SPENDING) FOR ';
  END IF;
  IF :P4_TIME='MONTH' THEN
  v_sql := v_sql || ' MONTH IN (''01'',''02'',''03'',''04'',''05'',''06'',''07'',''08'',''09'',''10'',''11'',''12''))';

  'Use generic column names (analysis of query during execution only)'

  column of the report used PL/QL name

  Hello

  Your body of the function doesn't return anything.
  Maybe it works

  declare

• Is it possible to make the condition depending on the sql statements in the data models

  Hi all
  
  Is it possible to include the condition based on sql statements in the data models.
  
  For example

  if (some parameter is not null)
  <sqlstatement name="STATEMENT_1">
  ...
  </sqlstatement>
  else
  <sqlstatement name="STATEMENT_2">
  ...
  </sqlstatement>

  Is something like this? Also, the good doc is available for ' how to take full advantage of the "data models" in BI Publisher?
  
  Thank you
  -Sookie

  Hello Sookie,
  I couldn't find the time to get a data model of demonstration of work for you, but I'll try to explain.

  First, write a PL/SQL package. Make sure that you set all the parameters of model of data such as a global variable in the default PL/SQL package.

  CREATE OR REPLACE
  package as employee
  function BeforeReportTrigger return Boolean;
  query_text varchar (2000);
  number of p_DEPTNO;
  END;
  /

  CREATE OR REPLACE
  package as body employee
  function BeforeReportTrigger return Boolean IS
  Start

  IF (p_DEPTNO = 10) THEN
  query_text: = select col1, col2, col3 from HR.
  elsif (p_DEPTNO = 20) THEN
  query_text: = select col1, col2, col3 hr_history.
  on the other
  query_text: = select col1, col2, col3 hr_history1.
  end if;
  Returns true;
  end;
  /

  Use this package in the default package in your data model. Check the "defaultPackage ="employee"in the following data model header.

  Sample data model
  ------------------------------
  
  
  
  
  
  
  
  
  
  
  
  
  --

  --
  --
  
  

  Before running the query SQL, data engine reads the "before the release of the report" and all the texte_requete argument based on the p_DeptNo value. When executing the Q1, engine sqlQuery analyze the query ' & quert_text and replace it with the actual value. For example if the p_deptno = 10, the query will be "select col1, col2, col3 from HR.

  Try it...

• REP-0737: must be a function of return type 'ref cursor.

  Hi all

  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

  begin
    Open My_Cur for select * from scott.emp order by deptno;
    return My_Cur

  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;

  BEGIN

  OPEN the RC to SELECT * FROM emp;

• Create the object type with a member function that returns an array of the object type

  Hello

  Is possible to compile code like this in Oracle SQL?

  CREATE OR REPLACE TYPE type_obj IS OBJECT (
    MEMBER FUNCTION f RETURN table_obj
  );
  
  CREATE OR REPLACE TYPE table_obj AS TABLE OF type_obj;
  
  

  In Java, it would be possible.

  Thanks in advance

  Circular dependencies must be resolved by means of REF pointers and incomplete type definition.

  See: Oracle objects management

  CREATE or REPLACE TYPE type_obj;

  /

  CREATE or REPLACE TYPE table_obj AS TABLE OF ref type_obj;

  /

  CREATE or REPLACE TYPE type_obj () IS OBJECT

  fake number

  Table_obj RETURN of the FUNCTION MEMBER f

  );

  /

  Now, it must implement the body of type.

  Note that a table of the REFs is not very useful in the plain of PL/SQL, the underlying data must be stored in a nested table if you want to use.

• Using the function PLSQL return Record Type Index of Tables in ADF

  I have a PLSQL function, a return type. My ultimate goal is to take this binary integer index Table and print it on the screen...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table ;
END my_pkg;

  
  

  OPTION 1:
  

  1) has anyone got best practices to accept plsql RECORDS returned by a function?

  Here is an example.

  http://adfpractice-Fedor.blogspot.SG/2013/01/working-with-PLSQL-procedures-in-ADF-BC.html

  But it will be a lot of work... first of all accept the results in a loop... then store in a temporary storage can be a few VO or global temporary table and then display them on the page

  
  

  OPTION 2:

  Using the functions PIPLELINED and use in the select statement.  While I can use this select statement in the SQL query to create VO... and drag and drop the VO...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table PIPELINED;
END my_pkg;

  
  

  select * from table(my_pkg.return_table);

  
  

  Wow... I'm so smart! .. really possible?  who is the best/possible/recommended option?

  I'm sure that will be the question most read by many who wants to use PLSQL instead of JAVA to the treatment and CHOSEN to use only to display the output of the PLSQL functions or procedures.

  
  

  Thank you

  Do you mean the scope of the defined Type pkg will be finished?

  I created guy outside the pkg as 'Create Type' if it works in this case?

  Yes, level objects schema (created with "create or replace type...") can be used in java and this can work.

  I think that then the scope of this TYPE will remain until the user session passes.

  Object definitions is not worn, but have their bodies.

  So, if you instantiate the data level object type schema in a plsql function, scope of this object is this function.

  Of course, if you instantiate the object as a variable package, then life of this object is equal to the lifetime of the package (which usually equals life of session db).

• function not returning object table properly

  Rather than return a table, my function returns this:
  
  SCHEMA_OWNER. TBL_SUMS ([SCHEMA_OWNER. SUMS_OBJ])
  
  Did anyone see a syntax error in my function or the DOF of my table and object types?
  
  It is a stripped down, simplified version of my function:
  
  create or replace FUNCTION "F_TEST" (number of p_skey, p_start_date date, p_end_date date)
  RETURN tbl_sums
  
  IS
  
  tmp_A NUMBER;
  tmp_B NUMBER;
  
  l_tbl tbl_sums: = tbl_sums();
  
  BEGIN
  
  SELECT SUM (FieldA), SUM (FieldB)
  in tmpA, tmpB
  FROM MaTable where SKEY = p_skey
  and DATE_VALUE > = p_start_date
  and DATE_VALUE < p_end_date;.
  
  l_tbl.extend;
  l_tbl (l_tbl. (Count()): = sums_obj (p_start_date, p_end_date, p_skey, tmpA, tmpB);
  Return l_tbl;
  
  END;
  
  My models are:
  
  create or replace type sums_obj is object (DATE start_date, end_date DATE, skey NUMBER, SumA, SumB NUMBER);
  create or replace type tbl_sums is table of the sums_obj;
  
  
  Thank you!

  >
  RETURN tbl_kpi

  What is 'tbl_kpi '? Which is not defined anywhere. Your original post said:
  >
  RETURN tbl_sums
  >
  We cannot help you if you don't publish what you actually use. Cut & paste is ok, but you have to paste the correct code.

  Your function returns a TABLE, but it is NOT in the PIPELINE. For example, if you query the DOUBLE function you will get a DATASET as a result.

  If you query the function AS A TABLE, you will get the "content" of the table.

  If you make your function a PIPELINED function then you use PIPE ROW to return each line but the function is always declared to return a TABLE. This is perhaps what is confusing you.

  Try the following code to see what the difference is.

  Here are two SQL types based on the EMP table in the scott schema.

  -- type to match emp record
  create or replace type emp_scalar_type as object
    (EMPNO NUMBER(4) ,
     ENAME VARCHAR2(10),
     JOB VARCHAR2(9),
     MGR NUMBER(4),
     HIREDATE DATE,
     SAL NUMBER(7, 2),
     COMM NUMBER(7, 2),
     DEPTNO NUMBER(2)
    )
    /
  
  -- table of emp records
  create or replace type emp_table_type as table of emp_scalar_type
  /
  

  Now - here's a function (similar to yours) that returns him EMP_TABLE_TYPE. NOTE: the function IS NOT PIPELINED

  CREATE OR REPLACE function SCOTT.get_emp1( p_deptno in number )
    return emp_table_type
    as
  tb emp_table_type;
  BEGIN
    select emp_scalar_type(empno, ename, job, mgr, hiredate, sal, comm, deptno)
      bulk collect into tb from emp where deptno = p_deptno;
    return tb;
  end;
  /
  

  If I simply select the function itself twice I get this:

  select get_emp1(20) from dual
  
  GET_EMP1(20)
  (DATASET)
  

  I can use TOAD or sql developer to examine this dataset and see the documents.

  But I can actually query the records by using the TABLE function:

  select * from table(get_emp1(20))
  
  EMPNO     ENAME     JOB     MGR     HIREDATE     SAL     COMM     DEPTNO
  7369     SMITH     CLERK     7902     12/17/1980     800          20
  7566     JONES     MANAGER     7839     4/2/1981     2975          20
  7788     SCOTT     ANALYST     7566     4/19/1987     3000          20
  7876     ADAMS     CLERK     7788     5/23/1987     1100          20
  7902     FORD     ANALYST     7566     12/3/1981     3000          20
  

  This is a similar function. It returns the same EMP_TABLE_TYPE, but it is a PIPELINED function.

  -- pipelined function
  create or replace function get_emp( p_deptno in number )
    return emp_table_type
    PIPELINED
    as
     TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
      emp_cv EmpCurTyp;
      l_rec  emp%rowtype;
    begin
      open emp_cv for select * from emp where deptno = p_deptno;
      loop
        fetch emp_cv into l_rec;
        exit when (emp_cv%notfound);
        pipe row( emp_scalar_type( l_rec.empno, LOWER(l_rec.ename),
            l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno ) );
      end loop;
      return;
    end;
    /
  

  The ONLY way I can query this function is using the TABLE function:

  select * from table(get_emp(20))

  The query of the PIPELINED function is the same and the result set is the same.

  The difference is that the PIPELINED function returns ONE LINE at a time and does NOT need to accumulate a large amount of data in a collection before returning. This collection uses the memory of expensive PGA and the more data you have the more memory it uses.

  Your function (and my only similar) return NO data until it has produced ALL of this. And he uses this expensive PGA memory. What is the point to create your collection at a time line and wait until you have everything before send it back you?

  You can easily modify your function and add PIPELINED to the declaration. Then, use the PIPE ROW clause to return each row that it is produced. Which will eliminate the need of collecting (and memory) within the service.

  You can also then follow up calls to function if you need to.

  See 'Use of functions Table in pipeline and parallel' in the data cartridge Developer Guide
  http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28425/pipe_paral_tbl.htm

  There is little use for your function that is not in the pipeline, but returns a type of table, unless you used to store the array type in a column of an object table.

  There are many uses for PIPELINED functions.

• a function that returns the type with a table joint!

  Good day to all,
  I have a function that returns a type.
  
  so I select it as:
  Select * from table (function (param1, param2))
  
  now I want to combine this with a table so that the settings for the service we get from the join table. Is this possible? And how?
  I tried different options without success.
  
  something like:
  Select *.
  table table (function (b.column1, b.columnb) x), tablea b
  where x.a = b.col
  
  Is this possible?
  
  Thanks in advance?

  Not sure I like it. What is the real problem that this method (driving a pipeline with input of a base table rows) is supposed to address? There may be a simpler and more elegant approach...

  The only way I know is function in pipeline:

  create or replace
    package pkg1
      is
        type traRecord
          is record(
                    ename emp.ename%type,
                    sal   emp.sal%type
                   );
        TYPE traArray IS TABLE OF traRecord;
        function f1
          return traArray
          pipelined;
  end;
  /
  create or replace
    package body pkg1
      is
      function f1
          return traArray
          pipelined
        is
            v_rec traRecord;
        begin
            v_rec.ename := 'Sam';
            v_rec.sal := 1000;
            pipe row(v_rec);
            v_rec.ename := 'John';
            v_rec.sal := 1500;
            pipe row(v_rec);
            v_rec.ename := 'Mary';
            v_rec.sal := 2000;
            pipe row(v_rec);
            return;
      end;
  end;
  /
  

  Now, you can:

  SQL> select * from table(pkg1.f1)
    2  /
  
  ENAME             SAL
  ---------- ----------
  Sam              1000
  John             1500
  Mary             2000

  Don't forget, it will create the generated system types:

    2  /
