• Select the missing cdr_repository CDR files after execution of a car to execute sql * statement?

  Hi all

  Hoping someone can provide some tips.  I need to export all the records 'date' with dateb cdr'.

  To do this, I started by ssh'ing in the pub and make a ' execute sql select auto * from tbl_billing_data where date (datetimestamporigination) between 'date' and 'date'

  A large amount of data came on the screen, so I ran ' file list activelog.net/cm/cdr_repository/preserver/et a list of directories to date appeared.  All directories of came from the "date", as if all the dates before that date have been removed.  Is it possible that to run the sql command that he actually removed these records cdr or moved him somewhere else?  Hoping that they are still usable, all advice appreciated.

  Thank you very much

  Hi Erina,

  The sql queries that you mentioned will not remove or push files to another folder. You have a server billing for this cluster configuration? Please see the section ""Troubleshooting: CDR Files will not be transferred to the billing server ' from the following link "

• Several SQL statements with zero executions in the region of SQL

  Hello

  one of my databases has a large number of statements in the SQL box with zero executions. Some of them analyzed several times without a single run. Why the database stores these statements and how to avoid or reduce them?

  My problem is that the only time or zero time sql statements take the largest part of the area of sql:

  -sql statement and only once and without executing sql statements

  Select

  Count (1) num_sql_total,.

  sum (decode (executions, 1, 1, 0)) num_one_use_sql,.

  This is not unusual. Another app could analyze for example hard the most often used SQLs in upstairs app - making benefit of further processing (in theory) of sweet analysis when you use these SQLs.

  In fact, I remember reading something to this effect as a performance for some factor or another Oracle document or note?

  So unless you have serious questions of shared pool, why bother with these sliders? What would be the problem?

• Identify the SQL statements that are executed frequently

  I would like to identify SQL statements that are executed may times (e.g., > 1000 times) during an interval AWR.

  I am aware of coloring a SQL_ID with exec ('...') dbms_workload_repository.add_colored_sql; but then the SQL ID must be known.

  Is it also possible to do the same for the (not yet known) SQL statements that are executed > 1000 times? I think that the SQL statements that run very quickly (for example 1 s <) won't be captured automatically in a CWA even if those statements are frequently performed.

• Order of execution of SQL statements

  Hello

  I have two SQL statements where the first statement executes on a table with more than 40 million lines, the second statement is running on a table more 6 million lines.  When they are running their own each take about 0.15 seconds to run, but when combined they take 20 minutes to run, (the second SQL statement is inserted in the WHERE clause of the statement of first).  It would seem that after combining these statements, the first statement goes through all 40 million lines before it performs the SELECT in the WHERE clause.  I think that what is necessary is to ensure the SELECT in the WHERE clause is executed first... or something like that!  Anyone has any ideas on how to combine these statements but not suffer from the performance impact?

  The first statement is:

  Select csi.instance_id,

  OEL.ordered_item

  of apps.csi_item_instances csi,.

  Apps.oe_order_lines_all oel

  where csi.instance_id in

  (1718000,3698000,48740202)

  and csi.last_oe_order_line_id = oel.line_id;

  The second statement is:

  Select / * + INDEX (IEA (attribute_id)) * /.

  IEA.instance_id

  apps.csi_iea_values do

  where iea.attribute_id = 10004

  and iea.attribute_value is not null;

  The joint return is:

  Select csi.instance_id,

  OEL.ordered_item

  of apps.csi_item_instances csi,.

  Apps.oe_order_lines_all oel

  where csi.instance_id in

  (select / * + INDEX (IEA (attribute_id)) * /)

  IEA.instance_id

  apps.csi_iea_values do

  where iea.attribute_id = 10004

  and iea.attribute_value is not null)

  and csi.last_oe_order_line_id = oel.line_id;

  Thanks for any help,

  Mike

  Your subquery returns probably just two values that you did originally as constants - but the optimizer thinks that you're going to get 564 K lines.  This is why the indicator for the simple query has a beneficial effect, it forces the Oracle to use an index when it would otherwise make a search.

  When the subquery is incorporated, however, the optimizer uses its cardinality expected to decide whether to use a nested loop join or the hash join to CSI_ITEM_INSTANCES, since the large enough estimate, he uses the hash with a join analysis complete.  That's why I pointed out that the fact to tell the optimizer to how many lines outside the subquery should make a difference.

  Have you tried the "common table expression" approach, rather than approach no_merge, but it would not help because it does not change the optimizer for cardinality estimate.  If you want to repeat the method CTE adding boards / * + materialize cardinality (2) * / to the query in the WITH clause, you should get the desired result.

  PL/SQL does not query instructions, only SQL performs.

  Basically, what you're trying to do is a very bad idea. Why I say this is the thought crossed my mind sometimes, back and I initially thought that it's a cool thing to store SQL table. But after several discussions, I learned to know the bad side of this.

  You can check this post in ask tom. I posted a few months ago.

• 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;

  -----

  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.

• See all SQL statements that have been executed in a transaction active?

  When I ask transaction$ v, $session of v and v$ sql, all that I see is the SQL statement being executed in a transaction active.
  How can I view all of the SQL statements that were executed as part of an operation running since the beginning of this transaction?

  If you use database 11g, you can use bed > view and manage Transactions that shows all the steps of sql in transactions.

• How to execute dynamically generated using GR 11, 2 SQL statements?

  Hello
  
  I would like to know if it is possible to do what the following statement which is intended :
  

  select * from (select replace('select empno from emp',
                               '',
                               '') from dual);

  in other words, is it possible to dynamically generate and execute a select statement in a from clause?
  
  Thank you for your help,
  
  John
  
  Published by: 440bx 16 July 2010 15:57 modified 'create' to 'generate' to the subject

  Like many I know no. in SQL. Results of your query in the FROM clause will not be transformed as another query, but just a litral value and your outer query returns this value as "select empno from emp".

  But you can use dynamic sql statements in PL/SQL using EXECUTE IMMEDIATE or DBMS_SQL.

  Something like that.

  DECLARE
   dynamic_from_clause VARCHAR2(4000) := 'select empno from emp';
   vReturnVal NUMBER;
  BEGIN
    EXECUTE IMMEDIATE 'SELECT * FROM ('||dynamic_from_clause||')' into vReturnVal ;
  END;
  /
  

  Just write memory have not tested it.

• How to execute the sql statement in the file beats?

  I want to execute after the statement
  C:\ > sqlplus/nolog
  SQL > conn scott/tiger
  SQL > select * from tab;
  
  I know I can achieve it following test.bat and testdb.sql file
  test.bat is:
  sqlplus/nolog @testdb.sql
  
  TestDB.SQL is:
  Conn scott/tiger
  Select * from tab;
  
  Now I don't want to use the sql file, I want only use bat file, as follows:
  test.bat is:
  sqlplus/nolog
  Conn scott/tiger
  Select * from tab;
  
  When I run test.bat, I find only one sqlplus /nolog execute statement, do not execute other statements.
  (1) I want to know if there is a method to run the SQL file by fighting without a sql file? How to make it happen?
  (2) if I call the sql file, how to hide the password of user? Because I don't want other people to know scott password, if I use conn scott/tiger in testdb.sql, other person can see testdb.sql and the password. Is there a good way to avoid?
  
  Thank you!

  It works a bit different in Windows. Create a file is like this:

  (
    echo conn scott/tiger@orcl
    echo spool c:\temp\list.txt
    echo select sysdate from dual;
    echo spool off
    echo exit
  ) | sqlplus -s -l /nolog

• Pass Pl/sql table in the USING clause in the EXECUTE IMMEDIATE statement

  Getting error when I try to pass the PL/SQL table in the USING clause in the EXECUTE IMMEDIATE statement:
  
  Declare
  result NUMBER;
  TYPE values_tab IS TABLE OF NUMBER INDEX OF directory;
  lv_tab values_tab;
  lv_exp varchar2 (300);
  lv_exec varchar2 (300);
  BEGIN
  lv_tab (1): = 5;
  lv_tab (2): = 48;
  lv_tab (3): = 7;
  lv_tab (4): = 6;
  lv_exp: = ': + b1: b2 + (: b3 *: b4)';
  lv_exec: = 'SELECT'. lv_exp | ' THE DOUBLE '.
  
  IMMEDIATE EXECUTION
  lv_exec
  IN
  result
  USING
  lv_tab;
  DBMS_OUTPUT. Put_line (result);
  
  END;
  /
  
  Error on line 1
  ORA-06550: line 20, column 12:
  PLS-00457: expressions must be SQL types
  ORA-06550: line 15, column 8:
  PL/SQL: Statement ignored
  
  
  I am trying to evaluate the expression ': + b1: b2 + (: b3 *: b4) "which is stored in the table. This table has different expressions (expressions about 300). I want to use the bind variable in the expression because each expression evaluated thousands of time may be more in some cases. If I use bind variable can he fill pool.
  
  Is there a way I can pass parameters with the HELP of (IN) dynamically instead of write "help lv_tab (1), lv_tab (2), lv_tab (3), lv_tab (4)? As number of change of the input parameters depend on the expression in the table.
  
  If it is possible please suggest any other ideas/approaches
  
  Help, please...

  Well, you keep changing faster reqs that I can follow. In any case, assuming that N-th variable bind (left to right) corresponds to n-th collection item:

  Declare
      result NUMBER;
      lv_tab values_tab := values_tab();
      lv_exp varchar2(300);
      lv_exec varchar2(300);
      lv_i number := 0;
  BEGIN
      lv_tab.extend(4);
      lv_tab(1) := 5;
      lv_tab(2) := 48;
      lv_tab(3) := 7;
      lv_tab(4) := 6;
      lv_exp := ':5000135+:5403456+(:5900111*:5200456)';
      lv_exec := lv_exp;
      While regexp_like(lv_exec,':\d+') loop
        lv_i := lv_i + 1;
        lv_exec := REGEXP_REPLACE(lv_exec,':\d+',':b(' || lv_i || ')',1,1);
      end loop;
      lv_exec := 'BEGIN :a := ' || lv_exec || '; END;';
  DBMS_OUTPUT.PUT_LINE(lv_exec);
  EXECUTE IMMEDIATE lv_exec USING OUT result,IN lv_tab;
  DBMS_OUTPUT.PUT_LINE(result);
  END;
  /
  BEGIN :a := :b(1)+:b(2)+(:b(3)*:b(4)); END;
