• Performance issue Bulk Insert PL/SQL table type

  Hi all
  
  I put in work of a batch to fill a table with a large number of data records(>3,000,000). To reduce the execution time, I used PL/SQL tables to temporarily store data that must be written to the destination table. Once all documents are piling up in the PL/SQL table I use a FORALL operator for bulk insert the records in the physical table.
  
  Currently, I follow two approaches to implement the process described above. (Please see the code segments below). I need to choose how to best wise performance between these two approaches. I really appreciate all the comments of experts about the runtime of the two approaches.
  
  (I don't see much difference in consumption of time in my test environment that has limited the data series. This process involves building a complex set of structures of large product once deployed in the production environment).
  
  
  Approach I:_
  DECLARE
  TYPE of test_type IS test_tab % ROWTYPE directory INDEX TABLE;
  test_type_ test_type.
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  test_type_ (ins_idx_) .column1: = value1;
  test_type_ (ins_idx_) .column2: = value2;
  test_type_ (ins_idx_) .column3: = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  I_ FORALL in 1.test_type_. COUNTY
  INSERT INTO test_tab VALUES (i_) test_type_;
  END;
  /
  
  
  Approach II:_
  DECLARE
  Column1 IS a TABLE OF TYPE test_tab.column1%TYPE INDEX DIRECTORY.
  Column2 IS a TABLE OF TYPE test_tab.column2%TYPE INDEX DIRECTORY.
  Column3 IS a TABLE OF TYPE test_tab.column3%TYPE INDEX DIRECTORY.
  column1 column1_;
  column2_ Column2;
  column3_ Column3;
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  column1_ (ins_idx_): = value1;
  column2_ (ins_idx_): = value2;
  column3_ (ins_idx_): = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  FORALL idx_ in 1.column1_. COUNTY
  INSERT
  IN n_part_cost_bucket_tab)
  Column1,
  Column2,
  Column3)
  VALUES)
  column1_ (idx_),
  column2_ (idx_),
  column3_ (idx_));
  END;

  Performance is more than just reducing the execution time.

  Just as smashing a car stops more than a car in the fastest possible time.

  If it was (breaking a car stopping all simply), then a brick with reinforced concrete wall construction, would have been the perfect way to stop all types of all sorts of speed motor vehicles.

  Only problem (well more than one actually) is that stop a vehicle in this way is bad for the car, the engine, the driver, passengers and any other content inside.

  And pushing 3 million records in a PL/SQL 'table' (btw, that is a WRONG terminology - there no PL/SQL table structure) in order to run a SQL cursor INSERT 3 million times, to reduce the execution times, is no different than using a brick wall to stop a car.

  Both approaches are pretty well imperfect. Both places an unreasonable demand on the memory of the PGA. Both are still row-by-row (aka slow-by-slow) treatment.

• Retrieve data from PL/SQL block and generate the UNIX data file

  Hi all
  
  I comply the following Unix Shell Script code block. The following code was generated the file count_curdate.txt with all need info. The query gives the number of records, the partition_dt group
  
  ABC ='sqlplus-s < < of folklore > count_curdate.txt
  uname/paswd@ConnectString
  SET THE OFF POSITION;
  SELECT COUNT (*) | «, » || partition_dt of the XYZ group by partition_dt;
  "exit";
  END '
  
  But now I need to change the above code to use dbms_application_info.set_module in it. Could someone let me know how to generate the file using PL/SQL in Shell Script block. I have tried following written code, but it generates count_curdate.txt file with 0 bytes.
  
  ABC ='sqlplus-s < < of folklore > count_curdate.txt
  uname/paswd@ConnectString
  Set serveroutput on;
  SET THE OFF POSITION;
  Set feedback off;
  BEGIN
  DBMS_APPLICATION_INFO.set_module (' shm.ksh ',' get account per day ");
  FOR again IN (SELECT COUNT (*):) «, » || partition_dt as 'DCount"of the XYZ of partition_dt group);
  LOOP
  DBMS_OUTPUT. Put_line (reccur. DCount);
  END LOOP;
  end;
  /
  "exit";
  END '

  Hello, your PL/SQL is not successfully completed, i.e.,.

  This:

  ABC=`sqlplus -s < count_curdate.txt
  uname/paswd@connectstring
  set serveroutput on;
  SET HEADING OFF;
  set feedback off;
  BEGIN
  dbms_application_info.set_module ('shm.ksh','get count by day');
  FOR reccur IN (SELECT COUNT(*)||','||partition_dt as "dcount" from XYZ group by partition_dt);
  LOOP
  DBMS_OUTPUT.PUT_LINE(reccur.dcount);
  END LOOP;
  end;

  Thanks, but I don't want to store the value in a table.

  Why not? The best place for data is in a SQL table - where is can be indexed, ordered, filtered, put together and so on.

  It is also not such a thing as a «+ table PL +» This data structures is nothing like a table. It is a collection or a table - which is the correct terminology and terminology for the same data structures in languages ranging from Pascal to Java for Delphi and C/C++.

  Calling it a + "PL table +" creates the false idea that the data structure is SQL table as... which could not be further from the truth. They have almost nothing in common. There is a huge difference between a table and a collection from a table SQL.

  I want to
  table ALIGNMENT (TYPE list IS TABLE OF r_empobj ;) is assigned (type r_empobj IS RECORD (empid number, ename varchar2 (100));)

  These data resides inside the PL language like PL data structures It is not a structure of SQL data.

  The SQL language and the language PL are different languages with different runtimes. PL/SQL integrates and "connects" them--blurs the border between these two languages. But they are still clearly distinct and different languages.

  If you have three choices:
  

• write a quick-sort /-bubble sort to sort the data PL. structure plastic
  
• Copy the entire structure of data of PL SQL data structure, use the SQL engine for sorting and then copy the entire structure of SQL data in PL.
  
• do not use a collection/table of PL structure, but use a SQL table instead.

• retrieving data from columns of user defined type

  Abstract types, I learned the other day. So I created an abstract type and a table.
  
  Create the student_ty as an object type
  (name varchar2 (20), number of roll);
  
  create table result)
  Student student_ty,
  (total);
  
  
  
  I also inserted data. But I'm having some trouble with the rretrieval of data. Suppose I want to choose only the roller and the name of the student as described in the type of studen. So I used the follwing query: -.
  
  Select result student.name;
  
  But it's not working. But when I use something like this: -.
  Select r.total, r.student.name in result r;
  
  
  This works perfectly. My question is that it is a rule that oracle needed to use an alias, whenever retrieve values for a user defined type data?. Help, please.
  Thanks in advance.

  Yes, you can use an alias when the type of object in a table like this.

  select r.student.name, r.student.roll, r.total

  My requirement is that.

  In general, Yes, if the function is a function table, you can do something like:

  select  t.col1,
          t.col2,
          f.col1,
          f.col2,
          f.col3
    from  table_name t,
             table(some_table_function(param1,...paramN)) f

• Reading the data from the XML file to the SQL Tables.

  I have XML of this type
  
  < empdept >
  < employees_marks >
  < emp_id > 1 < / emp_id >
  BUS from < DIVISION_ID > < / DIVISION_ID >
  PRE < JOB_ID > < / JOB_ID >
  SMITH of < first-name > < / name >
  JAMES < LAST_NAME > < / LAST_NAME >
  < > 10000 salary < / salary >
  < / employees_marks >
  
  < dept >
  < dept_details >
  < deptid > 10 < / deptid >
  < deptname > mechanical < / deptname >
  < / dept_details >
  < dept_details >
  < deptid > 20 < / deptid >
  < deptname > civilian < / deptname >
  < / dept_details >
  < dept_details >
  < deptid > 30 < / deptid >
  < deptname > ICE < / deptname >
  < / dept_details >
  < / dept >
  ((< / empdept > '));
  
  With the above format am able to recover data successfully to relational tables.
  
  
  < employees_marks emp_id = 1 DIVISION_ID = BUS JOB_ID = salary PRE = 10000 / >
  
  
  < dept_details deptid = 10 deptname = "Mechanical" / >
  < dept_details deptid = 20 deptname = "ECE" / >
  < dept_details deptid = 30 deptname = "EEE" / >
  
  that is, I have data as attributes rather than elements, if can I know the way how can I reach the requirement.
  
  How to recover data when it is present as attributes rather than elements.

  with temp as (
    select xmltype('') tempxml from dual
  )
   SELECT extractvalue(tempxml,'/employees_marks/@emp_id') empid,
    extractvalue(tempxml,'/employees_marks/@DIVISION_ID') divid ,
    extractvalue(tempxml,'/employees_marks/@JOB_ID') jobid      ,
    extractvalue(tempxml,'/employees_marks/@salary') sal
     FROM temp
