• How to make the output of Sql Plus with an error Code

  Dear members,
  
  How can I define sql more exit with an error code.
  
  We have a simultaneous host program. The executable is a shell script for this program. This sql script Shell script request which in turn gives call to a custom database package that I built.
  
  The flow rate is:
  
  
  -> SQL-> CUSTOM PACKAGE SCRIPT SHELL SCRIPT
  
  Custom package has two PARAMETERS of the error indicator and the error message. If something fails in the package these two PARAMETERS is returned with a value.
  
  So my sql script code looks like this:
  
  WHENEVER SQLERROR EXIT 251
  WHEN the OSERROR EXIT 251
  Set serveroutput size 1000000
  set linesize 32767
  set verify off
  set the position
  Set feedback off
  
  DECLARE
  x_error_message VARCHAR2 (1000);
  x_sql_message VARCHAR2 (1000);
  x_exception EXCEPTION;
  e_value NUMBER;
  
  BEGIN
  dbms_output.put_line ('Inside sql file');
  
  
  XXpackage.xxproc (x_error_message, x_sql_message);
  
  
  IF (x_error_message IS NOT NULL) AND (x_sql_message IS NOT NULL) THEN
  RAISE x_exception;
  END IF;
  
  
  EXCEPTION
  WHEN X_EXCEPTION THEN
  e_value: = 1;
  DBMS_OUTPUT. Put_line (' Exit Code: ' | e_value);
  DBMS_OUTPUT. Put_line ('X_EXCEPTION: EXCEPTION IN SCRIPT xpoext04a.sql :'||) SQLERRM);
  DBMS_OUTPUT. Put_line ('x_error_message is: ' | x_error_message);
  DBMS_OUTPUT. Put_line ('x_sql_message is: ' | x_sql_message);
  DBMS_OUTPUT. PUT_LINE (' ERROR IS: ' |) SQLERRM);
  WHILE OTHERS THEN
  e_value: = 252;
  DBMS_OUTPUT. Put_line (' Exit Code: ' | e_value);
  DBMS_OUTPUT. Put_line (' OTHER: EXCEPTION IN SCRIPT xpoext04a.sql :'||) SQLERRM);
  DBMS_OUTPUT. Put_line ('x_error_message is: ' | x_error_message);
  DBMS_OUTPUT. Put_line ('x_sql_message is: ' | x_sql_message);
  DBMS_OUTPUT. PUT_LINE (' ERROR IS: ' |) SQLERRM);
  
  
  END;
  */*
  output
  */*
  
  
  As you can see from above, if the two PARAMETERS have value, then it goes to an exception.
  
  My problem is that if it goes with the exception of X_EXCEPTION, the sql is not come away with a mistake. I mean sql is not treat this case like a sqlerror.
  
  
  How can do us more sql dating a sqlerror so that the host program must fail.
  
  
  Thank you

  the plu sql is not come away with a mistake. I mean sql is not treat this case like a sqlerror.

  This is because there is no error. You handled the exception.

  You can try adding a STIMULUS; at the end of your exception section. This re-triggers the exception so sql liked to see it.

• SQL Plus - guest user with: "do you want to continue?

  I am running a script, PL/SQL using SQL more. In the middle of the script, I would essentially like to have the following logic:
  
  Request to the user: "do you want to continue?
  IF the user types 'Y', continue with script (run update instructions)
  ELSE IF
  types user 'n' end script
  
  What is the best way to do it? Thank you!

  You cannot ask for PL/SQL code. The PL/SQL code runs in a process on the database server and can interface with the end front of the customer.
  You must use a front-end interface for this apart from any PL/SQL code. SQL * Plus offers a basic intervention, but you would be better using a good front-end such as Application Express, .NET, Java etc. or maybe even a Windows command/batch file.

• Why PL/SQL procedures does not allow users to enter data dynamically at run time?

  Dear all,

  I tried to do a procedure that will search for a group of approval in our database that matches.

  (1) the number of levels

  (2) the number of users by each level

  (3) the id of users by level

  entered by the user.

  I tried various methods to receive user input dynamically at run time, but in vain.

  Finally finished my procedure allowing the user to enter the parameters and then executes the procedure, to which these parameters are passed as arguments. (1 variable for the number of levels and 2 userdefinedarrays with the number of users by level and level respectively)

  Why PL/SQL procedures does not allow users to enter data dynamically at run time?

  Thanks in advance,

  Hello Sir,

  My question is that if I'm going to say, the number of levels 5, is there any way by which, at runtime, the procedure prompts me to enter at the start of the number of users per level. Now as soon as I get the number of users per level can I do the procedure ask me to enter the nicknames of the members of each level. I mean, something like a invite.

  Thank you

  Séverine Suresh

  There is no way to do it in SQL or PL/SQL, because not SQL PL/SQL is a way to get user input.  User interaction is a job for your front end, like Zlatko tool suggested in response to #5.  If your front end tool is SQL * Plus, you can use the substtitution variables, as Jarkko showed in response #6.

  The data is stored correctly, as shown in the PICTURE, even if you really do not have the data expected if I'm only guessing.

  The problem is most likely with the police. Your command prompt is implemented with code 850 (WE8PC850), but the police page seems to be in the code page 437 (US8PC437). You should change the font to a non-raster font or change page codes and NLS_LANG to the code page 437.

  Note, do not define NLS_LANG in system properties, because it affects so Oracle Forms. Set only in the command prompt given.

  SQL> 
  
  
  OS : Fedora Core 17 (X86_64) Kernel 3.6.6-1.fc17.x86_64

  I would like to ask a question about SQL * Plus SET SERVEROUTPUT option on / off and its impact on queries on views such as v$ sql and v$ session. This is the problem
  
  In fact I define three variables in SQL * Plus to store sidcolumns, serial # and prev_sql_id of session $ v in order to be used later, several times in various other queries, while I work always in the current session.
  
  So, here's how
  

  SET SERVEROUTPUT ON;  -- I often activate this option as the first line of almost all of my SQL-PL/SQL script files
  
  SET SQLBLANKLINES ON;
  
  VARIABLE mysid NUMBER
  VARIABLE myserial# NUMBER;
  VARIABLE saved_sql_id VARCHAR2(13);
  
  
  -- So first I store sid and serial# for the current session
  BEGIN
      SELECT sid, serial# INTO :mysid, :myserial#
      FROM v$session
      WHERE audsid = SYS_CONTEXT('UserEnv', 'SessionId');
  END;
  /
  
  
  PL/SQL procedure successfully completed.
  
  
  -- Just check to see the result
  SQL> SELECT :mysid, :myserial# FROM DUAL;
  
      :MYSID :MYSERIAL#
  ---------- ----------
         129   1067
  
  SQL> 

  Now let's say I want to run the following query as the last SQL statement is executed within my current session

  SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;

  According to the reference of database Oracle® 11 g Release 2 (11.2) description of session $ v
  
  http://docs.Oracle.com/CD/E11882_01/server.112/e25513/dynviews_3016.htm#REFRN30223]
  
  column prev_sql_id includes the sql_id of the last executed sql statement for the sid and serial data which, in the case of my example, it will be the above mentioned query SELECT on the employees table. So right after the SELECT statement on the employees table I have run the following

  BEGIN
      SELECT prev_sql_id INTO :saved_sql_id
      FROM v$session 
      WHERE sid = :mysid AND serial# = :myserial#;
  END;
  /
  
  PL/SQL procedure successfully completed.
  
  SQL> SELECT :saved_sql_id FROM DUAL;
  
  :SAVED_SQL_ID
  --------------------------------
  9babjv8yq8ru3
  
  SQL> 

  The value of sql_id, I'm supposed to find all the information on the sliders for my SELECT statement and also its value sql_text in v$ sql. Here is what I get when I query v$ sql on the stored sql_id

  SELECT child_number, sql_id, sql_text 
  FROM v$sql 
  WHERE sql_id = :saved_sql_id;
  
  
  CHILD_NUMBER   SQL_ID          SQL_TEXT
  ------------  --------------   -------------------------------
  0              9babjv8yq8ru3    BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES); END;

  So instead of

  SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;

  get the next value for the value of sql_text

  BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES);

  Which is of course not what I expected to find in v$ sql for the given sql_id.
  
  After a little googling, I found the next thread on OTN forum, where it was suggested (well, I think that may not be exactly the same problem) to disable SERVEROUTPUT.
  
  Problem with dbms_xplan.display_cursor
  
  It was exactly what I did

  SET SERVEROUTPUT OFF

  After that, I repeated the procedure as a whole and this time everything worked pretty much as expected. I checked SQL * more documentation for SERVEROUTPUT
  and also the page of v$ session, yet I don't find nothing indicating that SERVEROUTPUT should be operated off every time that views such as v$ sql, v $session
  are queired. I don't really understand the link in what concerns the impact that can have on the other or better say rather, why is there an impact
  
  Could someone kindly do a few details?
  
  
  Thanks in advance,
  
  Kind regards
  Dariyoosh

  Hi Dariyoosh,
  SET SERVEROUTPUT ON has the effect of dbms_output.get_lines running after each statement. Not only related to the system view.

  Below is what Tom Kyte is explained in this page:

  Now, sqlplus sees this feature and says "Hey, it wouldn't be nice for me to empty the buffer to the screen for the user? Thus, they added the command SQLPlus "set serveroutput we" which does two things

  (1) he tells SQLPLUS you would like run dbms_output.get_lines after each statement. You would like to make this network rounded up after each call. You want that this additional load will take place (think of a script of installation with hundreds / thousands of statements to run - maybe, just maybe you don't want this extra call after each call)

  (2) SQLPLUS automatically calls the API dbms_output "activate" to activate the buffering which is in the package.

  Kind regards.

• 30EA2 - SQL Developer Vs Index SQL/Plus functional on column Date

  I just spotted this while using EA3.2, but it may also exist on other versions, I will consider. I'm on a 9i 9.2.0.7 box, but will see if I can recreate on an instance of 10 or 11
  
  The question is, if I create a shadow table
  
  CREATE TABLE paul_test
  (
  CREATION_DATE DATE,
  DATE of creation_date2,
  last_updsate_date DATE,
  date of last_updsate_date2
  )
  ;
  
  If I then create a functional index on creation_date via SQL Dev:
  
  create index pt_idx1 on paul_test (nvl (creation_date, ' 01-JAN-4000'));
  
  and create a functional index on creation_date2 via SQL more
  
  create index pt_idx2 on paul_test (nvl (creation_date2, ' 01-JAN-4000'));
  
  What I see when you perform a describe table statement and looking at the index or when querying ALL_IND_EXPRESSIONS on the table TABLE_NAME is the following:
  
  SQL Dev index is: NVL("CREATION_DATE",'01-JAN-4000')
  
  The Index of over SQL is: NVL ('CREATION_DATE2', TO_DATE ('4000-01-01 00:00:00 ',' yyyy-mm-dd hh24:mi:ss'))))
  
  Why are they not compatible?
  
  If I then fill up with 1 million rows and fill creation_date/creation_date2 with enough data to make no small enough value I then collect statistics on the table and explain the plans of selects on creation_date/creation_date2 via SQL dev. and SQL Plus what I see, it's different

  The select on creation_date2 says plan is different between Dev SQL and SQl Plus. SQL Dev does not seem to be implicitly convert the '' 01-JAN-4000 in a date.
  
  Their behaviour are not the same?

  Then the problem may be due to different configurations of NLS between SQLPlus and SQLDeveloper, try to check the date format configured NLS in SQLPlus and SQLDeveloper.

  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?

• Connect SQL Developer, SQL * Plus can't

  I installed Oracle Database Development VM VM: VM VirtualBox for developers & lt; / title & gt; & lt; meta name = & quot; Title & quot; content = & quot; VM VirtualBox for developers & q...

  Added two adapters, one as a host-only, as NAT.

  We add a few entries tnsnames.ora for network database servers.

  Developer SQL inside the VM can connect to all three databases: XE, remote_db1 and remote_db2.

  SELECT * FROM Dual using a remote connection returns the data immediately.

  SQL * Plus inside the VM can connect to XE, but not to a remote server. It hangs just for awhile and finally back: ORA-12545: Connect failed because target host or object does not exist

  Outside of the virtual machine (on the host), Developer SQL (database connection Type) and SQL (sqlplus connection string) can connect to all three systems.

  What is going on?

  Brian Tkatch wrote:

  Sounds like the hostname resolution failed.

  A host name must be resolved to an IP address. If you use a host name in the TNS connection string, you need to make sure that it can be resolved to an IP address. With the help of the ping command is an easy way to determine if the host name is resolved.

  Some listeners (such as remote control and headphones RAC), accepts a connection client and in response redirect the client to a different hostname (and port). For example, a remote listener can serve 10 cases (each with a different service name). The client connects, asking servcice5. The listener redirects the customer to hostname ora-Server5 on port 1521. The customer now tries to connect to ora-Server5, to resolve the hostname to an IP address and then make the call to connect.

  If the listener can redirect the customer to a new host name - and the customer must be able to resolve the host name. The error that you get so don't always relates to the connection initial listener. It can also occur when the client driver follows the redirect to the listener and attempt a new connection to a new host.

• Use FOR... LOOP counter in the treatment of PL/SQL procedures with nest. Table

  Hi all!
  I learn PL/SQL on the book by Steve Bobrovsky (specified below, sample comes from it) and I have a question.
  
  In the procedure of the below specified program used a currentElement integer variable to get the reference to the line in the nested table of data type % ROWTYPE.
  Meanwhile, the program itself uses a common FOR... LOOP counter I have.

  DECLARE
   TYPE partsTable IS TABLE OF parts%ROWTYPE;
   tempParts partsTable := partsTable();
   CURSOR selectedParts IS 
    SELECT * FROM parts ORDER BY id;
   currentPart selectedParts%ROWTYPE;
   currentElement INTEGER;
   PROCEDURE printParts(p_title IN VARCHAR2, p_collection IN partsTable) IS
    BEGIN
     DBMS_OUTPUT.PUT_LINE(' ');
     DBMS_OUTPUT.PUT_LINE(p_title || ' elements: ' || p_collection.COUNT);
     currentElement := p_collection.FIRST;
     FOR i IN 1 .. p_collection.COUNT
     LOOP
      DBMS_OUTPUT.PUT('Element #' || currentElement || ' is ');
       IF tempParts(currentElement).id IS NULL THEN DBMS_OUTPUT.PUT_LINE('an empty element.');
       ELSE DBMS_OUTPUT.PUT_LINE('ID: ' || tempParts(currentElement).id || ' DESCRIPTION: ' || tempParts(currentElement).description);
       END IF;
      currentElement := p_collection.NEXT(currentElement);
     END LOOP;
   END printParts;
  BEGIN
   FOR currentPart IN selectedParts
   LOOP
    tempParts.EXTEND(2);
    tempParts(tempParts.LAST) := currentPart;
   END LOOP;
   printParts('Densely populated', tempParts);
   FOR i IN 1 .. tempParts.COUNT
   LOOP
    IF tempParts(i).id is NULL THEN tempParts.DELETE(i);
    END IF;
   END LOOP;
   FOR i IN 1 .. 50
   LOOP
    DBMS_OUTPUT.PUT('-');
   END LOOP;
   printParts('Sparsely populated', tempParts);
  END;
  /

  When I substituted a global variable of INTEGER type such for... The LOOP counter, an APEX have returned an error "ORA-01403: no data found.

  DECLARE
   TYPE partsTable IS TABLE OF parts%ROWTYPE;
   tempParts partsTable := partsTable();
   CURSOR selectedParts IS 
    SELECT * FROM parts ORDER BY id;
   currentPart selectedParts%ROWTYPE;
   PROCEDURE printParts(p_title IN VARCHAR2, p_collection IN partsTable) IS
    BEGIN
     DBMS_OUTPUT.PUT_LINE(' ');
     DBMS_OUTPUT.PUT_LINE(p_title || ' elements: ' || p_collection.COUNT);
     FOR i IN 1 .. p_collection.COUNT
     LOOP
      DBMS_OUTPUT.PUT('Element is ');
       IF tempParts(i).id IS NULL THEN DBMS_OUTPUT.PUT_LINE('an empty element.');
       ELSE DBMS_OUTPUT.PUT_LINE('ID: ' || tempParts(i).id || ' DESCRIPTION: ' || tempParts(i).description);
       END IF;
     END LOOP;
   END printParts;
  BEGIN
   FOR currentPart IN selectedParts
   LOOP
    tempParts.EXTEND(2);
    tempParts(tempParts.LAST) := currentPart;
   END LOOP;
   printParts('Densely populated', tempParts);
   FOR i IN 1 .. tempParts.COUNT
   LOOP
    IF tempParts(i).id is NULL THEN tempParts.DELETE(i);
    END IF;
   END LOOP;
   FOR i IN 1 .. 50
   LOOP
    DBMS_OUTPUT.PUT('-');
   END LOOP;
   printParts('Sparsely populated', tempParts);
  END;
  /

  When I tried to manage this code in SQL * Plus, the following picture emerged:

  Densely populated elements: 10
  Element is an empty element.
  Element is ID: 1 DESCRIPTION: Fax Machine
  Element is an empty element.
  Element is ID: 2 DESCRIPTION: Copy Machine
  Element is an empty element.
  Element is ID: 3 DESCRIPTION: Laptop PC
  Element is an empty element.
  Element is ID: 4 DESCRIPTION: Desktop PC
  Element is an empty element.
  Element is ID: 5 DESCRIPTION: Scanner
  --------------------------------------------------
  Sparsely populated elements: 5
  DECLARE
  *                                                 
  ERROR at line 1:                                  
  ORA-01403: no data found                          
  ORA-06512: at line 14                             
  ORA-06512: at line 35

  What's not in the code (or what I did not understand)? Help please!

  Your error occurs because you are dealing with a sparsely populated collection and using an index for items that do not exist.

  For collections of the low density of population, you must iterate through using FIRST and THEN as modeled not from 1 to COUNT.

  The crucial difference between your code and the example is:

  tempParts(i)
  

  Which, as you have demonstrated, doesn't work very well (!) if there is no item (i).

  The code example is a little unusual in my opinion.

     currentElement := p_collection.FIRST;
     FOR i IN 1 .. p_collection.COUNT
     LOOP
      ...
      currentElement := p_collection.NEXT(currentElement);
     END LOOP;
  

  It works, but it's an unusual way to iterate through a collection of rare which is perhaps most often done like this:

     currentElement := p_collection.FIRST;
     WHILE(currentElement IS NOT NULL)
     LOOP
      ...
      currentElement := p_collection.NEXT(currentElement);
     END LOOP;
  

  Which is perhaps less open to confusion.

  In the end, the distinction between

  tempParts(currentElement).id
  

  and

  tempParts(i).id
  

  is crucial.

• Out of the queue of SQL * Plus for Excel

  I'm out of the queue of SQL * Plus for Excel. The code I use is down. I want that all white space to carve when I open the updated file waiting in Excel. How can I ensure this?
  
  I was reading on the SET TRIM command, but it says that it does not affect the output queued. (http://ss64.com/ora/syntax-sqlplus-set.html)
  
  Is there a way to NOT display whitespace at the beginning and the end of a column in SQL * more? In other words, if I shoot a single column of a record, and a data element is only 3 characters in length, I want to be also 3 characters instead of extending over 40 characters across the width of the column.
  
  
  The column for your troubleshooting information
  IDNUMBER is NUMBER (12)
  FIRST is VARCHAR2 (40)
  The LAST is VARCHAR2 (60)
  
  
  Code
  SET LINESIZE 100
  SET PAGESIZE 0
  SET MARKUP HTML PREFORMAT ON
  set colsep,
  coil c:\prospects.csv
  Select '' perspective ID"', '" First"',""finally" "from dual;
  Select to_char (p.idnumber), p.first, prospect_view p.last p where idnumber = 164515;
  spool off

  TRIM affects the expressions in your SELECT clause. It has nothing to do with the padding of SQL * Plus adds to align the columns upwards.

  Is there a way to NOT display whitespace at the beginning and the end of a column in SQL * more? In other words, if I shoot a single column of a record, and a data element is only 3 characters in length, I want to be also 3 characters instead of extending over 40 characters across the width of the column.

  Here's a way to make the main request:

  SELECT        TO_CHAR (idnumber)
  || ',' ||  first
  || ',' ||  last
  FROM           prospect_view
  WHERE        idnumber     = 164515
  ;
  

  This will include spaces only if they occur in first or last. Depending on your data and your requriements, you may need to use the FILLING (first) instead of the first, and/or TRIM (finally) instead of the last.

  Using this technique, it does not matter what is COLSEP: the query produces a single column.

  Use the SQL * more order

  SET  TRIMSPOOL ON
  

  to keep SQL * more add space after this single column.

• Call the PL/SQL procedure with in out parameter of OIC clob

  Hello
  
  For a few days, I am facing a problem. I have to call the pl/sql procedure with colb parameter out. I use c ++ and OIC (don't ask me why :)).
  
  I use a pl/sql problem test procedure:
  
  create or replace function Test (longField outside clob) return number is
  Number of result;
  Start
  longField: = 'prefix ';
  Result: = 12;
  Return (result);
  end Test;
  
  So I do all the stuff with the connection to the DB,
  
  I prepare the statement: "start: res: = test(:param); end; »
  So I OCIHandleAlloc (m_pCtx-> hpEnv,
  (void *) & m_hpStatement,.
  OCI_HTYPE_STMT,
  0,
  (NULL);
  and
  OCIStmtPrepare (m_hpStatement,
  m_pCtx-> hpErr,
  (...),
  (...),
  OCI_NTV_SYNTAX,
  OCI_DEFAULT);
  
  Before the binding I prepare parameters. For a clob I devote to the lob Locator:
  
  OCIDescriptorAlloc ((dvoid *) m_pCtx-> hpEnv, (dvoid *) & m_pLobLocator,)
  (ub4) OCI_DTYPE_LOB (size_t) 0, (dvoid *) 0);
  OCILobEnableBuffering (m_pCtx-> hpContext, m_pCtx-> hpErr, (OCILobLocator *) m_pLobLocator);
  
  that I bind parameters using OCIBindByName and OCIStmtExecute statement execution.
  
  I get an error
  ---------------------------
  Microsoft Visual C++
  ---------------------------
  Unhandled exception in... (ORAOCIEI11. (DLL): 0xC0000005: Access Violation.
  
  My question is: is it possible to call the pl/sql procedure with parameter BEAK clob?
  If Yes, what steps I need to do to succeed?
  
  Thank you for your response.

  Hello

  Of course, it is possible :)

  Show that you are your piece of code that is binding.
  Are you sure you had correctly the lob descriptor in the call to bind?
