  Dear Experts,
  
  I need a clarification. Is it possible to use the fn - bea: function execute sql (Oracle Service Bus) to perform an insert operation in a database with the data extracted from the message of the Organization (i.e. $body/Info/username)? If it is possible which is the right syntax?
  Any suggestion is appreciated.

• How to fill a variable in the script with the sql statement

  Hello

  I am trying to replace the toad by SQL Developer. I would like to start a main script, which selects the database name and host name and makes this information on behalf of a spoolfile and then rolls into this spoolfile.

  As a result, I am able to see when and on what database the spoolfile belongs to.

  With SQL * more or Toad, I was able to make it work with:

  set SKRIPTNAME = "Mainscript_Release_4.04_00".

  Set serveroutput on

  undefine spoolfile

  column spoolfile new_value by spoolfile

  SELECT ' & SKRIPTNAME' | ' _'|| ora_database_name | » _'|| LOWER (HOST_NAME) | » _'|| To_char (sysdate, 'yyyymmdd_hh24miss'): '. Newspaper ' spoolfile of v$ instance;

  coil & & spoolfile

  -call other scripts here

  spool off

  Anyone knows a solution for this in SQL Developer scripts?

  Best regards, Stefan

  Just use this script. It worked for me.

  I made a small adjustment - something SQLDev could write, vs, I changed the default directory that will be the directory \bin that they run on.

  

• Help with the insert statement

  Hello
  
  I was wondering if someone could help write me a sql statement.
  
  Here is my table:
  

  CREATE TABLE "TEMP_INVOICE" 
     ("INVOICE" VARCHAR2(100 BYTE),
       "DATE_OF_DOCUMENT" DATE, 
       "DATE_OF_PAY_DAY" DATE, 
       "D" NUMBER, 
       "K" NUMBER
     );

  Here are the instructions for correct insertion. This time, I posted 2 examples with 2 numbers different otherwise.

  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.02.2012','dd.mm.yyyy'),to_date('01.03.2012','dd.mm.yyyy'),5000,0);
   
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.04.2012','dd.mm.yyyy'),'','',1000);
   
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.05.2012','dd.mm.yyyy'),'','',3000);
   
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.06.2012','dd.mm.yyyy'),'','',1000);
  
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (2000,to_date('01.07.2012','dd.mm.yyyy'),to_date('01.09.2012','dd.mm.yyyy'),8000,0);
   
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (2000,to_date('01.10.2012','dd.mm.yyyy'),'','',5000);
   
  insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (2000,to_date('01.11.2012','dd.mm.yyyy'),'','',2000);

  I want to do is make an insert allows you to table another call is MADE:
  

  CREATE TABLE "INVOICE" 
     ("INVOICE" VARCHAR2(100 BYTE),
      "DATE_OF_DOCUMENT" DATE, 
       "DATE_OF_PAY_DAY" DATE,
       "DATE_OF_PAYMENT_REC" DATE,
       "VALUE" NUMBER,
       "VALUE_DEDUCT" NUMBER,
      "DATE_FROM" DATE,     
       "DATE_TO" DATE
       );

  Statements in the INVOICE table should be like this:
  
  
  ........ The Bill... date_of_document... date_of_pay_day... date_of_payment_rec... value... value_deduct... Date_from... Date_to
  1......     1000...............1.1.2012.................1.3.2012................NULL............................ 5000... NULL... 1.3.2012...1.4.2012
  2......     1000...............1.4.2012.................NULL..................... 1.4.2012...1000... 4000... 2.4.2012... 1.5.2012
  3......     1000...............1.5.2012.................NULL..................... 1.5.2012...3000... 1000... 2.5.2012... 1.6.2012
  4......     1000...............1.6.2012.................NULL..................... 1.6.2012...1000
  
  
  Can someone help me with the sql statement that would insert data from table to table Bill temp_invoice as in the example?
  
  Thank you!
  
  PS
  
  I would try to explain.
  (1) the first statement that is to be inserted is original imply that at which is different DATE_OF_PAY_DAY to NULL.
  To this inserted negative of the original imply, we must add date_from that is exatly the same date_of_pay_day and date_to which is exactly the same as the date of the first payment. Payment which came first!
  (2) we have now in the second insert statement. It will be the first payment of lease with date_of_document and date_pf_payment_rec, which is the same as date_fo_document. Value field will be populated with the amount of payment received and value_deduct field will be the value of the original imply - value of the first payment. Date is date_of_document + 1 and date_to is the date of the next payment.
  (3) Insert us the next installment. Date_od_payment_rec is the same as date_of_document... value is the amount of the second payment and value_deduct's previous value_deduct which was of 4000 - value of this second payment. date_from date_of_payment_rec + 1 and date_to is the date of the next payment
  
  So we continue this same pattern until we reached the final payment when we finish insert with the statement:
  Date of the document (date of the last payment received) and even for date_of_payment_rec and field value with the amount of the payment receieved. The rest (value_deduct, date_from, date_to) is null.
  
  I really hope you understand what I'm trying to do here.
  
  If you have any other questions please.

  Ok!
  Be sure to post the results you want new data.

  You probably need to add "PARTITION BY the Bill" to all analytical clauses in my solution:

  INSERT INTO invoice
  ( invoice, date_of_document, date_of_pay_day, date_of_payment_rec
  , value,   value_deduct,     date_from,           date_to
  )
  SELECT       invoice
  ,       date_of_document
  ,       date_of_pay_day
  ,       CASE
             WHEN  k > 0
             THEN  date_of_document
         END          AS date_of_payment_rec
  ,       NVL (d, k)     AS value
  ,       NVL2 ( date_of_pay_day
              , NULL
              , SUM (d) OVER ( PARTITION BY  invoice
                                        ORDER BY      date_of_document
                       )
              - SUM (k) OVER ( PARTITION BY  invoice
                                        ORDER BY      date_of_document
                       )
              )     AS value_deduct
  ,       NVL ( date_of_pay_day
             , date_of_document + 1
             )          AS date_from
  ,       LEAD (date_of_document) OVER ( PARTITION BY  invoice
                                          ORDER BY      date_of_document
                             )
                        AS date_to

  Because I'm not an English speaker nativ, that I just posted what it should look like after the insert is successful.

  OK, so you can't explain as you want, but you still need to explain.

  Point out where my solution is the production of incorrect results, and explain (as you can) how to get good results in these places.

• VIX file in the user interface designer receives the data from the Web service application that communicates with the SQL server database

  I created the Web service VI ("Mt-insolacije.vi"), which has two terminals of the input string (FROM / TO) for the dates of arrival and exit of two data terminals (table 1 d) from database (MS SQL server). This VI communicates with the database with functions of the database with a DSN and SQL query appropriate palette. There are two tables with two data (time and Insolation) columns in the database.

  This VI works when you run in Labview 2010, but when I used it as VI in UI Builder it returns no data.

  Could you please help me find a solution. Is it possible to communicate with the SQL server database in this way or there is another way?

  There are two files attachmet: Image of .vix file in Interface builder and .vi file ("Mt-insolacije.vi")

  Please help me ASAP!

  Thank you

  Ivan

  I found the solution problem is in the DSN. I've been using the user instead of DSN system DSN.

  It's important to create the system DSN if you want your VI of web service to communicate with the database.

  PS Please put feature bundle format timestamp and XY graph in the web user interface designer. It's complicated to trace data with datetime on X axis without them.

• need help with the Update statement

  Hello
  I received a question in a course and I tried my best to respond, and now my brain is giving. I would really appreciate help with the update statement. I don't mind if you do not validate a solution, a little nudge in the right direction would be really useful. I'll post that I got.
  
  THE QUESTION
  / * For these agents disabled on more than seven missions, change their date of deactivation of the first date of deactivation of all the agents that have been activated in the same year as the agent that you update currently.
  */
  
  I have it divided into parts, here is my select statement to agents disabled on more than 7 missions, which produces the deactivation_dates in the agents table that I want to update...

  SELECT
  s.deactivation_date
  FROM
  (
  SELECT
  a.deactivation_date,
  count(m.mission_id) as nomissions
  FROM
  agents a
  INNER JOIN
  missions_agents m
  on
  a.agent_id=m.agent_id
  GROUP BY
  a.deactivation_date
  ) s
  WHERE
  s.nomissions>7 AND s.deactivation_date IS NOT NULL

  .. .and the code for the first date of deactivation for each year of activation agent

  select 
  a2.deactivation_date
  from
  agents a2
  where a2.deactivation_date= 
  (
  select min(a.deactivation_date)
  from 
  agents a
  where to_number(to_char(a.activation_date,'YYYY'))=to_number(to_char(a2.activation_date,'YYYY'))
  )

  ..... I am not real to marry these two statements together in the Update statement. I can't extract each date of deactivation produced in the first select statement and their match against the first date of deactivation in the year they have been activated for the second select statement.
  
  Any help greatly appreciated... :))

  I began to wonder how things would :)

  user8695469 wrote:
  First of all why he chooses the date the earliest of all agents

  UPDATE  AGENTS_COPY AC /* (1) */

  ,       AGENTS_COPY AC /* (2) */
  WHERE   TRUNC(AGS.ACTIVATION_DATE,'YEAR') = TRUNC(AC.ACTIVATION_DATE,'YEAR') /* (3) */
  )
  

  He recovers as soon as the subquery has not been correctly set in the SET clause. It seems you are trying to update a correlated, but we are still having a conceptual shift. I have added a few comments to your code above and below will explain.

  (1): when you do a correlated update it is useful to the table alias that you did right here.

  (2): this table statement is not necessary and is the reason why the FIRST deactivation date is selected. The alias that you use (3) refers to THIS table, not the one defined in the update statement. Remove the line indicated by (2) in the FROM clause and a correlated update will happen.

  and secondly why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)

  user8695469 wrote: then why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)

  
  WHERE EXISTS
  (
  SELECT
  a.agent_id,
  count(m.mission_id)
  FROM
  agents a
  /* INNER JOIN AC ON AC.AGENT_ID = A.AGENT_ID */
  INNER JOIN
  missions_agents m
  ON
  a.agent_id=m.agent_id
  GROUP BY
  a.agent_id,
  a.deactivation_date
  HAVING
  count(m.mission_id)>7 AND a.deactivation_date IS NOT NULL
  )
  

  Once again this problem is similar to the question above that a correlation update doesn't work. Test existence of lines in an EXISTS subquery. Since your subquery is not related to the table that you are trying to update, it will be always return a line and, therefore, it returns true for EACH LINE in the AGENTS table. To limit the game to only agents > 7 missions results, you need to add a join condition that references the table in your update statement. I added one above (with comments) as a sample.

  I recommend you look over all material that you have associated with correlated subqueries, including documents that I posted above. This seems to be what you're having the problem more with. If you need me to explain the concept of correlated queries any better please let me know.

  Thank you!

• How can I pass a condition of the table in the sql statement?

  For example, in the table in the COND Varchar2 column (200) there is the value ' VAR > 10'.

  | COND |

  |' VAR > 10' |

  where VAR is the name of the table column. I would like to make statement CASE WHEN VAR > 10 AND 0... I tried with as subquery

  WHEN BOX (SELECT COND FROM TABLE WHERE...) THEN 0, but it does not work.

  Hello

  You can do this by using dynamic SQL.

  that is to say:

  declare
    v_stm      varchar2(4000);
    v_cond      varchar2(100);
    v_result    integer;
  begin
    select cond
      into v_cond
      from yourtable
    where a=1;
  
    v_stm := 'select case when '||v_cond||' then 0 ...';
  
    -- dynamic sql
    execute immediate v_stm
      into v_result;
  
  end;
  /
  

  Remember that, in general, dynamic SQL has a performance degradation that SQL static and should be avoided when possible.

  Storage condition or the SQL statements in the tables is not a good practice.

  Kind regards.

• 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.

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?

  How do you paste the sql statement into sql * more... I tried the following options, get the windows interface for this sequel to the documentation below, but that did not work
  
  http://download.Oracle.com/docs/HTML/A88829_01/ch3.htm
  
  then I tried to create a simple .txt file with my sql statement and tried to run using @name (where name is the name of the file) and it gives me the following error SP2-0310: cannot open the file 'firstscriot.sql '.

  You name the file name.txt? Then you cannot start with @name, because SQL * PLUS will add the extension .sql

  Try instead the @name.txt or name the file name.sql

  And check if you have the correct path.

• CALL THE PROCEDURE IN THE SQL STATEMENT

  Why we cannot call a procedure inside the SQL statement?

  Hello

  Usually when you select an item should return you data. In the case of a procedure, you cannot return any return value from the procedure directly it has to be done through some settings and to access these settings, you cannot use a simple sql statement. Where as in a function, you must return one of data that can be easily obtained accordingly.
