• 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.

  Yes, he accepts a single parameter, but it can always be expression (as the concatenation: val1 | val2 | val3). In your case (.ename e_tab (x) |) ' ' || e_tab (x) .sal

• Is it possible to use the record type or a PL/SQL table in the Select statement

  Hi all
  
  My requirement is that.
  I want to write a query and write a function, function, I want to return multiple columns at the same time in a Select statement.
  I select the return values in the Select no statement in a PL/SQL block.
  Is it possible to use the PL/SQL Table or Variable of Type record, or any other method in the statement Select?
  
  Please help me understand the solution.
  
  
  Kind regards

  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

• How to create the constructor function for a pl/sql table?

  I created a PL/SQL type as table below:

  create or replace type typ_tbl_des_text is table of the typ_tof_des_text

  OK so far, but I would like to have a constructor function which would be subject to validations and raise_application_error when a validation condition is not met.

  How to do this?

  The typ_tof_des_text that I created with a constructor function, so that the record-level validation are performed in the constructor. And I think the postings between several records shall be made in a constructor for typ_tbl_des_tex, but cannot figure out how to create such a constructor.

  BEDE wrote:

  So, if I have understood correctly, to a plsql table type, I can't have a member procedure. Or can I? I mean, just as for a type of failure I can have one or more constructors and possibly several procedures of Member.

  For the standard tables in PL/SQL, you will need to create your own API (using procedures and functions) to handle beyond the basics provided by the language. No constructors and methods as it is no o - o.

  After thinking a little deeper, I reformulate what I said earlier and actually wants to have a member procedure called add_item, who would be first to check if an item with a key value exists and, if so, it would be up-to-date and so not only extend the plsql table.

  Two options.

  As we already mentioned, an associative array can be considered - note however that this structure of table has name-value pairs.

  Another method is to use a TWG (global temporary table). You define the structure of the once initial table. When a session uses the structure of the table, private copying is instantiated for this session. When the session ends, this copy is destroyed. The table is a temporary structure for this session only.

  It can include indexes and so on – which means you can use the constraints of primary keys, unique indexes, secondary indexes and so on.

  TWG scales are much better than collections or arrays that require a PGA (expensive private server) memory. In addition, SQL can be used natively against a GTT - unlike the arrays and collections.

• I can pass a pl/sql table as a parameter for a database adapter

  Hello
  
  I'm moving mutiple files back to a pl/sql stored procedure using a BPEL database adapter. Does anyone know if it is possible to make pl/sql tables to bpel as a parameter?
  
  The version of the database that we use is 8.1.7 and so I do not think that we use XMl types for transmitting data.

  Yes you can not spend the function PL/SQL nested tables in JDBC. You can pass simple values such as VARCHAR2, NUMBER and Oracle SQL object types (VARRAY, nested TABLE, OBJECT).

  Types defined in PL/SQL are simply not supported by the JDBC driver (except the basic support for the index per table, but 1 level of depth). PL/SQL types are not very good to use, because then you can not use them in SQL in PL/SQL statements, SQL types do not have these limitations.

  Help

  I can't go through your entire code. From there, you no need to use this plsql don't table as an input parameter because you do not pass anything... You're just fill with your values hard-coded... Then you can try the below stated

  DECLARE

  -declare the plsql table

  X_PWB_ORG_HIST_TBL APPS. XXINV_PWB_HIST_FCST_PUB. XXINV_PWB_ORG_HIST_TBL;

  BEGIN

  XXINV_PWB_HIST_FCST_PUB. GET_ORG_DETAILS (91, TO_DATE('02-FEB-2014','DD-MON-YYYY'), X_PWB_ORG_HIST_TBL);

  -The legacy output:

  BECAUSE me in X_PWB_ORG_HIST_TBL. FIRST... X_PWB_ORG_HIST_TBL. LAST

  LOOP

  -Add all columns to dbms_output print and test values

  DBMS_OUTPUT. PUT_LINE ('X_PWB_ORG_HIST_TBL =' |) X_PWB_ORG_HIST_TBL (i). Org_Hist_Index_Id | «, » || X_PWB_ORG_HIST_TBL (i). Item_Number);

• Not able to manage the value 'Table Type' in my procedure, humble need help here

  Hi all

  I am facing a problem with below pl/sql block. The time I run it it works fine, but when I run the procedure only from the exact values (hardcoded), it throws error as below.

  [Error] Execution (38: 1): ORA-06550: line 2, column 1:

  PLS-00306: wrong number or types of arguments in the call to 'CREATE_ABNORMAL_BY_TRADER '.

  ORA-06550: line 2, column 1:

  PL/SQL: Statement ignored

  What I understand problem is, I use a Type of table herewhich works very well with my Pl/Sql block, but do not work when I run the same procedure of the value hard-coded.

  Please guide me how to handle this situation.

  Pl/Sql block [works absolutely well]:

  Declare
  
  lv_eff_from_dt DATE;
  lv_eff_to_date DATE;
  v_severity_codes_wl param_tbl: = param_tbl();
  lv_algo_id_wl sagedbo.alerts.algo_id%TYPE;
  
  Begin
  
  lv_eff_from_dt: = sage_utility.get_transaction_date('EFF_FROM_DATE');  -' 05-Aug-2013. '
  lv_eff_to_date: = sage_utility.get_transaction_date('EFF_TO_DATE');       -' 04-sep-2013. '
  
  lv_algo_id_wl: = sage_utility.get_code_values('ALERT_MODELS','GRAY_LIST');  -GLABNORMAL

  v_severity_codes_wl: = sage_utility.get_multi_parameter_value(1,'SEVERITY_CODE_WL'); -4.5
  
  SONARDBO.sage_generate_alert.create_abnormal_by_trader (lv_algo_id_wl, v_severity_codes_wl, lv_eff_from_dt, lv_eff_to_date, 'US');

  End;

  Pl/Sql block [does not] (by the way the same values but hard)

  Begin

  SONARDBO.sage_generate_alert.create_abnormal_by_trader ('GLABNORMAL', '4', 5, 5 August 2013 ', ' 04-Sep-2013', 'US');

  End;

  Error PLS-00306: wrong number or types of arguments in the call to 'CREATE_ABNORMAL_BY_TRADER '.

  I'm sorry that my question is not so generic, you cannot run on your computer. How should just guide me with the concept, I treat the values in table hardcodedly? (For testing of use)

  Thank you very much

  If your passage of type table, then you will need to run as below

  Begin

  SONARDBO.sage_generate_alert.create_abnormal_by_trader ("GLABNORMAL", param_tbl (' 4 ', ' 5'), August 5, 2013 ', ' 04-Sep-2013', 'US');

  End

  Means that you must call with the table type ("' hard coded values"). Here is the simple test. Take a look at this

  SQL > CREATE or REPLACE the TYPE nt_tab IS TABLE OF VARCHAR2 (50);

  2.

  Type of creation.

  SQL > CREATE OR REPLACE PROCEDURE test_proc (p_nttab nt_tab)

  2 AS

  5 FOR me in 1.v_nttab. COUNTY

  6 LOOP

  7 DBMS_OUTPUT. Put_line (v_nttab (i));

  8 END OF LOOP;

  9 END;

  10.

  Created procedure.

  -Perform the procedure with only one value of type table

  SQL > EXEC test_proc (nt_tab ('KING'));

  KING

  PL/SQL procedure successfully completed.

  -Run procedure with the multi-value table type

  SQL > EXEC test_proc (nt_tab ('KING', 'AAAA', 'BBBB'));

  KING

  ABDELKADER

  BENAMER

  PL/SQL procedure successfully completed.

• How to execute a SQL statement that is stored within a SQL Table

  Hello

  If someone please help me with the following problem I would be eternally grateful

  I have a SQL statement that is stored inside a certain SQL table, I want to use this SQL statement inside my PL/SQL procedure.

  Thought a simple solution was to get the SQL statement in a table, and then run it, but how could I do so exactly with PL/SQL? I only started to play with PL/SQL in the last days.

  Thanks in advance!

  This is what it looks like more or less:

  Display result for:

  ---------------------

  SELECT TRIM (OBJ_VALU_TXT)

  OF OBJ_VALU_DOC

  WHERE TYPE_OBJET = 'FLD '.

  AND OBJECT_CODE = 15443

  AND OBJ_VALU_CD = 'CAB '.

  ORDER BYDOC_SEQ_NO

  00001

  ------------------------------------------------------------------

  SELECT

  VALUE (MAX (RECEIPT_NO) + 1,: OUT-COMP-FACTOR)

  THE FRONT DESK

  WHERE (RECEIPT_NO BETWEEN

  (: OUT-COMP-FACTOR AND: OUT TO A NUMBER) OR

  (RECEIPT_NO >: OUT-COMP-FACTOR AND)

  (: OUT-TO-NUMBER = 0)

  Here's a demo of your condition.

  create table t (col1 varchar2 (200));

  table created

  insert into values t ('select * from double ');

  1 row inserted

  declare
  v_col varchar2 (200);
  v_val varchar2 (200);
  Start

  Select col1 in t v_col;

  run immediately v_col in v_val;
  dbms_output.put_line (v_val);
  end;

  -----
  X

  Use in the clause, you can use as many variables as needed. But the basic approach remains the same.

  But storage in DB SQL is not an efficient design.

• PL/SQL tables

  Hello guys,.
  I have a few questions about the PL/SQL tables
  
  (1) if I don't specify the 'INDEX BY' clause, they are indexed by PLS_INTEGER default, right?
  
  (2) consider this package specification
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  So I created a table (I hope it's standard indexed by type of data pls_integer) and I am in him passing as parameter to a procedure. Because I want this parameter be optional I assign null inside.
  
  Now, I change the table definition for:
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  Try to compile it and you get:
  Error (5.53): PLS-00382: expression is of the wrong type
  
  Why?
  
  (3) because I need this optional parameter, I use the first statement:
  

  CREATE OR REPLACE PACKAGE Testxyz AS
  
  TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
  
  PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers := NULL);
  
  
  END Testxyz;

  Now I create an anonymous block, and you want to set something in the table
  

  DECLARE
     vtab_Numbers TESTXYZ.tab_Numbers;
  BEGIN
  
     vtab_Numbers(1) := 5;
  
  
  END;
  /

  When you try to run it, I got:
  06531 00000 - 'refers to an uninitialized collection.
  
  Can someone help me understand this problem?
  Is it possible to have input of type PL/SQL table setting and have a standard null, are assigned?
  
  Thanks, Dan

  (1) if I don't specify the 'INDEX BY' clause, they are indexed by PLS_INTEGER default, right?

  N ° or somehow.

  More critical, and using official terms of [url http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/composites.htm#CHDBHJEI] documentation so that we don't get into unnecessary arguments about the correct terms for these features, it's the difference between types of ASSOCIATIVE TABLE and the IMBRIQUEE TABLE collection.

  If you omit the "INDEX BY" clause, it is a type of TABLE IMBRIQUEE collection. A type of TABLE IMBRIQUEE is always indexed by PLS_INTEGER.

  When you include the ' INDEX OF ', this is an ASSOCIATIVE ARRAY.

  (2) consider this package specification
  Try to compile it and you get:
  Error (5.53): PLS-00382: expression is of the wrong type

  Why?

  Because you cannot assign NULL to an ASSOCIATIVE ARRAY.

  In the same way, you cannot do this:

  SQL> DECLARE
    2   TYPE tab_Numbers IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
    3   v1 tab_Numbers;
    4  BEGIN
    5   v1 := NULL;
    6  END;
    7  /
   v1 := NULL;
         *
  ERROR at line 5:
  ORA-06550: line 5, column 8:
  PLS-00382: expression is of wrong type
  ORA-06550: line 5, column 2:
  PL/SQL: Statement ignored
  
  SQL> 
  

  If you want two entry points to TestNumber with an ASSOCIATIVE ARRAY or NULL then overload the procedure.

  If you want to call a procedure with a TABLE IMBRIQUE collection type you can the default empty:

  SQL> CREATE OR REPLACE PACKAGE Testxyz
    2  AS
    3   TYPE tab_Numbers IS TABLE OF PLS_INTEGER;
    4   PROCEDURE TestNumber(ptab_Numbers IN tab_Numbers DEFAULT tab_Numbers());
    5   PROCEDURE TestNumber;
    6  END Testxyz;
    7  /
  
  Package created.
  
  SQL> 
  

  (3) because I need this optional parameter, I use the first statement
  When you try to run it, I got:
  06531 00000 - 'refers to an uninitialized collection.

  Because you have not initialized it.

  Different collection types require different semantics.

• Help with PL/SQL table

  Hi all
  
  Newbie when it comes to PL/SQL tables...
  
  Can someone explain to me why it works and how exactly I can do the following without triggering an error?
  
  I have a function that accepts a PL/SQL table like in parameter.
  
  The PL/SQL table is defined as...
  

  Type TTimeTable is table of xxtzg_otl_iface_stg%rowtype index by binary_integer;

  the xxtzg_otl_iface_stg table has many columns including error_message and error_flag. If I find an error, I want to update the error_message and error_flag function. If I can get it works I will then modify the function to return to the table of PL/SQL instead of BOOLEAN
  

  FUNCTION validate_timecard (pTimeTable IN TTimeTable
                                               ) RETURN BOOLEAN IS
  
    lc_module            CONSTANT VARCHAR2(25)        := 'validate_timecard';
    lEmployeeCount    PLS_INTEGER;
    lEmployeeError     VARCHAR2(1000);
    lErrorCount          PLS_INTEGER :=0;
    
    BEGIN
  
       FOR i IN 1 .. NVL(pTimeTable.COUNT,0) LOOP                                   
                                           
       xxtzg_concurrent_utils_pkg.write_log(  p_package =>  gc_package
                                                              , p_module  =>  lc_module
                                                              , p_text    =>  'Processing timecard for employee_number: '||pTimeTable(1).employee_number
                                                             );               
     
       -- Call validations before submitting the timecard to the API
       --validate employee
  
          begin
             select count(*)
               into lEmployeeCount
               from per_all_people_f
              where employee_number = pTimeTable(1).employee_number;
              
              if lEmployeeCount = 0 then
              
              -- Set the errors
  
              -- This assignment below does not work, I get an error message saying...
              --[Error] PLS-00363 (137: 27): PLS-00363: expression 'PTIMETABLE.ERROR_MESSAGE' cannot be used as an assignment target
  
              PTimeTable(i).error_message :=  'Employee Number '||pTimeTable(1).employee_number||' is not a valid employee';
              PTimeTable(i).error_flag := 'Y';
  
              end if;
              
          end;    
          
       END LOOP; 
       
       IF lErrorCount = 0 THEN 
       RETURN TRUE;
       ELSE
       RETURN FALSE;
       END IF;
                                             
    END;

  Your table is declared as IN only (the default if you do not explicitly set it), so you are not allowed to change its attributes in all respects, IN = read-only.

  If you want to be able to modify the values of a parameter, it must be declared as OUT parameters.

• doubt in PL/SQL table

  If I said PL/SQL table and populated with 10 values.
  
  If I want to find a perticular values are in the list populated how can I find.say I have values from 1 to 10.
  and I want to find if 9 is in the list.
  I tried with loop. Is there another way. I use 10g.
  
  declare
  tr_nm number_array;
  i the number;
  Start
  I'm in 1.10
  loop
  tr_nm.extend;
  tr_nm (i): = i;
  end loop;
  for j from 1... tr_nm. Count
  loop
  If tr_nm (j) = 9 then
  i: = i + 1;
  end if;
  end loop;
  If i > 0 then
  null;
  end if;
  end;

  Please try this code
  Note: this code runs from 10 g.

  DECLARE
  type num_type is table of NUMBER;
  v_num_arr num_type;
  v_num number;
  v_var number :=9;
  BEGIN
  select level
  bulk collect into v_num_arr
  from dual connect by level <=10;
  
  dbms_output.put_line('Count - '||v_num_arr.count);
  
  if v_var member of v_num_arr then
   dbms_output.put_line('Found ');
  end if;
  
  END;
