• 10g: re-raise the exception modifies the call stack

  Hello! I'm "Oracle PL/SQL Reference" and trying to re-raise the exception:
  

  begin
    dbms_output.put_line('line a');
    raise no_data_found;
  exception
    when others then
        dbms_output.put_line('line b');
        raise;
  end;

  Oracle reports exception was thrown on line 7, not 3. Apparently "re-raise" modifies the call stack, making it of no use: I can throw a new exception with the same success. It is not re - raise a conventional sense of the term. The question is, is there a possibility to actually STILL raise exception, without changing the call stack?

  A reference to 'Lines followed by Steven Feuerstein'

  Impact of multiple reminders

  Often, an exception occurs at the bottom of the execution stack. If you want this exception to propagate all the way to the PL/SQL block outside, it should be re-relief within each exception handler in the stack of blocks. Listing 3 shows an example of such an event.

  Code Listing 3: Re-raising exceptions to the outermost block on the stack

  CREATE OR REPLACE PROCEDURE proc1 IS
  BEGIN
     DBMS_OUTPUT.put_line ('running proc1');
     RAISE NO_DATA_FOUND;
  EXCEPTION
     WHEN OTHERS THEN
        DBMS_OUTPUT.put_line (
           'Error stack in block where raised:');
        my_putline (
           DBMS_UTILITY.format_error_backtrace);
        RAISE;
  END;
  /
  CREATE OR REPLACE PROCEDURE proc2
  IS
     l_str VARCHAR2 (30) := 'calling proc1';
  BEGIN
     DBMS_OUTPUT.put_line (l_str);
     proc1;
  END;
  /
  CREATE OR REPLACE PROCEDURE proc3 IS
  BEGIN
     DBMS_OUTPUT.put_line ('calling proc2');
     proc2;
  EXCEPTION
     WHEN OTHERS
     THEN
        DBMS_OUTPUT.put_line ('Error stack at top level:');
        my_putline (DBMS_UTILITY.format_error_backtrace);
        bt.show_info (DBMS_UTILITY.format_error_backtrace);
  END;
  /
  

  When I run the code in Listing 3, I see the following result:

  SQL> exec proc3
  calling proc2
  calling proc1
  running proc1
  Error stack in block where raised:
  ORA-06512: at "SCOTT.PROC1", line 4
  Error stack at top level:
  ORA-06512: at "SCOTT.PROC1", line 11
  ORA-06512: at "SCOTT.PROC2", line 6
  ORA-06512: at "SCOTT.PROC3", line 4
  
  Program owner = SCOTT
  Program name = PROC1
  Line number = 11
  

  When I call the function backtrace in the program at the lowest level, it correctly identifies the line 4 of proc1 as the line where the error is mentioned. I then re - raise the same exception using the statement of RECOVERY. When the exception propagates to the outermost block, I call the backtrace function once again and this time it shows that the error was raised at line 11 of proc1.

  This behavior, we can conclude that DBMS_UTILITY. FORMAT_ERROR_BACKTRACE watch the running back to the last trace LIFT during its session. As soon as you issue a STIMULUS to a specific exception or re - raise the current exception, you restart the cell which produces the backtrace function. This means that if you want to take advantage of the DBMS_UTILITY. FORMAT_ERROR_BACKTRACE, take one of the following two approaches:

  Call the function backtrace in the section of the exception to the block in which the error was raised. This way you have (and can connect) that line number critical, even if the exception is re-relief more further upward in the stack.
  Avoid exception handlers in your carpet intermediate programs and call the function backtrace in the section except for the outermost program in your stack.

• raise the exception ORA-00942

  -How to raise an exception for 6550 or 942?  Here is the anonymous block that I am running in SQL Developer, who does not throw an exception:
  
  --(J'ajouterais que c'est un exemple d'autonomes; le tableau "image_masterr" n'existe pas)
  
  -I am running in 10.2.0.1
  
  DECLARE
  lcl_temp1 VARCHAR2 (10);
  v_error_code NUMBER;
  v_error_message VARCHAR2 (255);
  no_table EXCEPTION;
  no_table_942 EXCEPTION;
  PRAGMA EXCEPTION_INIT(no_table,-06550);
  PRAGMA EXCEPTION_INIT(no_table_942,-00942);
  BEGIN
  DECLARE
  lcl_temp VARCHAR2 (20);
  BEGIN
  v_error_code: = SQLCODE;
  v_error_message: = SQLERRM;
  SELECT count (1) IN the lcl_temp of image_masterr;
  v_error_code: = SQLCODE;
  v_error_message: = SQLERRM;
  DBMS_OUTPUT. Put_line ("there is no problem ' |") lcl_temp);
  EXCEPTION
  WHEN no_table OR no_table_942 THEN
  DBMS_OUTPUT. Put_line ('there is a problem');
  WHILE OTHERS THEN
  DBMS_OUTPUT. Put_line ('there is a problem');
  END;
  DBMS_OUTPUT. Put_line ("it's no problem :'|| v_error_code | v_error_message);
  END;

  We must distinguish between exceptions at compile time and exceptions at run time. You can only handle exceptions at the moment is running. So if you have a static SQL referencing the nonexistent table you will get the compile error (btw, ora-06550 said explicitly you - compile error). Now if you have a dynamic sql code in your block PL/SQL with reference to non-existent table, you won't get compile time error. Exception will be thrown when you run the dynamic sql code. In this case, you can catch the error "table or view does not exist" and manipulate appropriatry.

• clear the table of loop for

  Hello world

  I have a question about the erasure of history to the table. It sounds simple, but I'm really confused...

  As the example attached below, I've built a table within a while loop and a loop. After totally run the program once, when I run it a second time, it seems that the table has a memory of the last time, that is the size of table does not start from 0, and appears the old number from last time, even through its initialization of the for loop.

  How can I make it go empty each time when I restart the table?

  Need your help. Thank you very much. : )

  You must also have a shift in the loop FOR. This will keep the data for the duration of the program, but it clear at the beginning of the next run.

• move the MCs with loop for?

  I am trying to find a way to move video clips with a for loop

  I have 10 points called t1d-dt10, and I want to be able to put them all to y = 200.

  I understand that I can put i = 1; i < 11; i ++

  as

  for (i = 1; i < 11; i ++) {}

  DT i._y plus 200 ;}

  or

  for (i = 1; i < 11; i ++) {}

  String("DT"+i)._y = 200 ;}

  but the rest is a mess, and does not, work or glitches. I still have to find a loop help file for the movement of several video clips.

  If you just want to immediately change the positions of the bodies, then using a for loop works fine, you just use the notation of support [] to have the strings to be interpreted as the name of the instances...

  for (i = 1; i<>

  This ["dt" + i] ._y = 200;

  }

• For the verification of loop fetch

  Hi experts,

  As everyone knows, for loop taken 100 lines per each iteration (network roundtrips to 100 by default). Please, if it is correct me if I'm wrong, I know the following codes are the same.

  
  

  for rec in (select * from employess)

  loop

  do_some_work

  end loop;
  

  
  declare

  cursor c is select * from custtable where rownum < 10;

  type of my_t is table of c%rowtype;

  REC my_t;
  

  if not c%isopen then

  Open c;

  end if;
  

  loop

  Fetch c bulk collect into rec limit 100;

  do_some_work

  output when rec.count = 0;

  end loop;

  Close c;
  

  My question is, when I try to check the FOR LOOP to retrieve the query 100 lines per iteration, I use view v$ sql. However, it does not work. Because the PL/SQL block is ready. I need not to see that the sql that is used in the LOOP FOR query. So, what should I do to check that the extraction of LOOP FOR 100 rows per each iteration? Dynamic operating modes should I watch?

  Thanks in advance.

  You can simply enable SQL_TRACE and check. I used a TEMP table that has 1000 rows.

  SQL > select count (*) temp;

  COUNT (*)
  ----------
  1000

  SQL > alter session set sql_trace = true;

  Modified session.

  SQL > alter session set tracefile_identifier = "kar28042014";

  Modified session.

  SQL > start
  2 for i in (select * from temp)
  loop 3
  4 null;
  5 end of loop;
  6 end;
  7.

  PL/SQL procedure successfully completed.

  SQL > alter session set sql_trace = false;

  Modified session.

  If you see the trace output, you can see 11 extraction operation is done. 10 * 100 = 1000 read lines. The extra 1 extraction is to check if there is nothing else to look for.

• Need help with the exception of slider

  Hello

  I have a small code with implicit cursor to retrieve rows in the unreadable_cards table, and then for each extracted value I search another table card_acnt to certain values and update data in the table unreadable maps. The code is as below

  declare

  number of v1;

  Start

  for v1 to (select engravedid in the unreadable_cards where case_resolved = 1)

  loop

  Update unreadable_cards set Serial_number = (select card_account Serial_number

  where ticketid = v1.engravedid)

  where engravedid = v1.engravedid;

  Update unreadable_cards set case_resolved = 2

  where case_resolved = 1

  Serial_number is not null;

  end loop;

  exception

  When no_data_found then

  Update unreadable_cards set case_resolved = 22

  where ticketid = v1.engravedid;

  When too_many_rows then

  Update unreadable_cards set case_resolved = 23

  where ticketid = v1.engravedid;

  When others then

  Update unreadable_cards set case_resolved = 24

  where ticketid = v1.engravedid;

  end;

  Here I have problem write values to the table as this error pops up for each reference to V1 in exception

  PLS-00487: Invalid reference to the variable "V1".

  I have to be able to raise all three exceptions in the loop so that v1 can be referenced and loop will not terminate on the meeting of the exception and complete for each row retrieved by cursor, so that I can track the status of each record based on the value of case_resolved.

  
  

  Any help would be much appreciated

  Thank you

  Let me to you that out of me... I don't like your code

  First thing you need to know, it's you won't hit NO_DATA_FOUND exception in an UPDATE statement. If an update has not changed a line, it does not raise an exception NO_DATA_FOUND. Check this

  SQL > start
  Update 2 emp set sal = sal + 10, where 1 = 2;
  3 end;
  4.

  PL/SQL procedure successfully completed.

  No exception. It's a thing, you have to watch.

  Second thing I don't like the way you used the WHEN OTHERS exception. What are the exception as you look? You should not have a when others without STIMULUS. IT a bug in the code. You must fix this.

  Assuming that your assignment CASE_RESOLVED logic, that's how.

  CASE_RESOLVED = 2 means you have found an exact match for your UNREADABLE_CARDS. ENGRAVEDID in CARD_ACCOUNT. TICKETID

  CASE_RESOLVED = 22 means that you do not have a match for your UNREADABLE_CARDS. ENGRAVEDID in CARD_ACCOUNT. TICKETID

  CASE_RESOLVED = 23 means that you have several game for your UNREADABLE_CARDS. ENGRAVEDID in CARD_ACCOUNT. TICKETID

  CASE_RESOLVED = 24, does not have any meaning. You have to drop that part.

  You can do this, you have no need for all that PL/SQL. A simple SQL way will do.

  Fusion in unreadable_cards x

  a_l'_aide_de)

  Select a.engravedid

  max (b.serial_number) Serial_number

  case when count (b.serial_number) = 1 then 2

  When count (b.serial_number) = 0 then 22

  When count (b.serial_number) > 1 then 23

  end case_resolved

  of unreadable_cards one

  left

  Join card_account b

  On a.engravedid = b.eticketid

  where a.case_resolved = 1

  Group

  by a.engravedid

  ) y

  on)

  x.engravedid = y.engravedid

  )

  When matched then

  update the value x.serial_number = nvl (y.serial_number, x.serial_number)

  x.case_resolved = y.case_resolved;

  Above is untested code. But should work. If any minor error fix it and you should be good to go.

• New loops for 10.1.1 even as new loops of logic?

  I have all the additional content for Logic Pro and with the exception of the fabric of Alchemy, are the new Apple Loops for Garageband 10.1.1 identical to what I already under Logic Pro?

  GarageBand gives me the option to download the entire library, which I don't want I don't have to.

  I suspect these new loops for GarageBand 10.1.1 are already in my folders of loops when I updated Logic Pro a few months ago?

  Thank you

  The App Store shows the update like this:

  

  2600 new Apple Loops and sounds.

  I also installed Logic Pro X.

  There is no new loops installed after 10.11.1 GarageBand update.   The last loop in Library/Audio/Apple Loops is 80 return Beat.caf frommay 2015

  

  GarageBand must have installed something, because the absence of plug-ins error messages are gone, when I open iOS projects GarageBand, but I can't find any new items in the folder/library.

• Management concept the exceptions that went wrong!

  Well, this is by far the most embarrassing hack code I've done so far... but it works. I'm trying to run a select where if there is no data or null returned, place it in the value "v_pidm"and then let the action happen.» Pretty simple, right? Fake! A select statement returns no data that uses a function 'en' is an exception... "no data found". Oracle, it sends to the exception block as it should. Well, I don't want to stop and start my script a million times here, I added a Begin/End sub, with an exception to handle the error to say and perform an insert. I know that you should not use a State of exception for inserts another capture errors... you know bad practices and all. Any ideas as how to better manage the select statement that must regularly return no data? I was thinking some along the line of nvl (v_pidm, 0) or something, but I get errors.

    WHEN no_data_found
    THEN

  END;
  

  It is perfectly reasonable to have exception handlers that make anything other than newspaper an exception if they can in fact wisely handle the exception (e.g., you know that the query may return 0 rows and you know how to handle this case correctly).

  You don't want an exception handler that simply calls to DBMS_OUTPUT. Put_line without re-raise the exception. It is a mistake to delay. And there is no real reason in this case to extract the SQLERRM in the variable error - it would be better to let the exception is propagated to the top so that you can see the full error stack.

• Raises an exception if the cursor failed

  Hi, how can I write an exception if a cursor was unable to retrieve the values in the variable? for example, I have 10 cursors in procedures from my store and I want if this cursor was not able to process then threw an exception. For example, code below, if the recovery process could not then triggered an error message like "failure on cursor c_get_card_dependencies.

  OPEN c_get_card_dependencies (v_POTENTIAL_CARDS.iv_sysid, v_POTENTIAL_CARDS.plp_log_pos_type);

  LOOP

  SEEK c_get_card_dependencies INTO v_CARD_DEPENDENCIES;

  EXIT WHEN c_get_card_dependencies % notfound;

  DBMS_OUTPUT. Put_line (LPAD ('SYS ID: ', LENGTH ('SYS ID: "") + 2' ') |) v_CARD_DEPENDENCIES.sysid);

  END LOOP;

  CLOSE C_get_card_dependencies;

  Put your OPEN... CLOSE in a BEGIN... END of block. Then, you can catch the exceptions for each cursor and raising your own exception

  BEGIN

  XY OPEN;

  ...

  NARROW xy;

  EXCEPTION

  WHEN VALUE_ERROR THEN

  raise_application_error (-20001, "failed on the xy cursor: ' |") SQLERRM, TRUE);

  END;

  When I set the exception inside the loop, as above, the procedure seems never to end, and I end up getting a 'NOWAIT' error when I try to remove the table or something like that.

  The code works fine if I remove the 'START' just after the loop and also out of the exception within the loop, but I want to be able to specify what's wrong with each record rather than deal with the correct records and then stop after that it is a record that has, for example, 9 values in a column that accepts only 6.

  Can anyone help with this?

  Thank you

  Play with my code I found what was wrong.
  I needed to add in the following line in my code block of exception:

• Issue with the exception of the loop

  Hello

  I had 4 database, I use dblinks to check some tables and write the results in a table. I have created a table to contain the instance names so that my loop check and perform my procedure.

  declare

  sql_string1 VARCHAR2 (4000);

  sql_string2 VARCHAR2 (100);

  Start

  sql_string2: = "truncate table Backup."

  immediately run sql_string2;

  for r in (select INSTANCE_NAME, del HOST_NAME)

  loop

  sql_string1: = ' insert into Backup

  SELECT "' | r.HOST_NAME | " '  '||', '''|| r.INSTANCE_NAME | " '  '||' ,

  INPUT_TYPE, STATUS, START_TIME, END_TIME V$RMAN_BACKUP_JOB_DETAILS@'|| r.INSTANCE_NAME;

  immediately run sql_string1;

  COMMIT;

  end loop;

  exception

  WHILE OTHERS THEN

  NULL;

  end;

  /

  If all listeners work or dbs work this procedure to work with no problems but if one of them is closed, simply insert the values until it gets error but I want that if she gets error will be another value. How can I do?

  I changed the values in the table led

  SYS@crofxd01:WSTORED: > select instance_name del;

  INSTANCE_NAM

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

  BLABLA

  BLABLA

  BLABLA

  BLABLA

  FPT

  only the FPT is actual instance after I performed the procedure, I want to see that FPT values inserted DB.

  Thank you

  You must move the exceptions in the loop. Like this

  declare
  sql_string1 VARCHAR2 (4000);
  sql_string2 VARCHAR2 (100);
  Start
  sql_string2: = "truncate table Backup."
  immediately run sql_string2;
  for r in (select INSTANCE_NAME, del HOST_NAME)
  loop
  sql_string1: = ' insert into Backup
  SELECT "' | r.HOST_NAME | " '  '||', '''|| r.INSTANCE_NAME | " '  '||' ,
  INPUT_TYPE, STATUS, START_TIME, END_TIME
  OF V$RMAN_BACKUP_JOB_DETAILS@'|| r.INSTANCE_NAME;
  Start
  immediately run sql_string1;
  exception
  When then
  null;
  end;

  COMMIT;
  end loop;
  end;

  But make sure that you specify that the exception in the EXCEPTION block. Do not THEN use than OTHERS. Because it will catch all exceptions (long-awaited by you and should not not by you). It will hurt one day.
