• How to return an error code of SQL * Plus of PL/SQL procedure

  Hello
  
  I want to be able to pass a variable back to the Unix script, and I have the following code
  
  ******************
  
  sqlplus/myuser mypass < < EOF
  WHENEVER SQLERROR EXIT 41.
  WHENEVER OSERROR EXIT 81;
  execute pkonp.run_onp;
  output
  EXPRESSIONS OF FOLKLORE
  
  ERRORCODE = $?
  
  If [$ERRORCODE! = 0] #test for successful onp
  then
  #Notify failure of the administrator of the ONP.
  echo 'Fail ONP to 'date' \n'
  FI
  
  ******************
  However, I am unable to get my PL/SQL to pass an error code to SQL * more.
  
  How to catch an error in PL/SQL and pass the SQL error code *, so that SQL * Plus can then pass the error to the Unix Shell script?
  
  Thank you very much.

  Yes - in a nut shell, you need to convert Oracle codes exception to the process of Linux/Unix/Windows exit codes as the number of exception Oracle is physically too large to fit into an integer to a byte that is used by the operating system for the exit codes.

  The best place to do this would be something like a SQL * more script as is the process real o/s which should only return exit code of the kernel.

• Can I connect SQL Developer to Essbase?

  I know that tools such as the table can connect to Essbase, but how can I connect Oracle SQL Developer to Essbase?

  You have not, I'm afraid.

  SQL Developer is a development tool for working with databases oracle that supports connections to a set of data bases third-parties for the purposes of specific to oracle migration.

  Third-party databases supported are listed in help, but from memory they are UDB DB2, MS SQl Server, Sybase, MySQL and Teradata.

  Developer SQL is not a tool of multiple databases.

• 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
  
  
  -Select
  NVL SELECT (creation_date, ' 01 - JAN - 4000 "")

  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.

  You can change the date format in SQLDeveloper, NLS of:

• Can I install SQL Plus in a client PC?

  Dear friends,
  
  I'm working on a PC that accesses the database using PL/SQL Developer and command-line SQLPLUS (instant client). I would like to download SQL PLUS as well. Is there a way? I've seen some way PC but don't know how to do it.
  
  Could someone guide me.
  
  Thanks in advance.
  
  Looking for your support.
  
  Benard

  My apologies. I did not yet installing Oracle11g customer and assumed it was the same as Oracle 10g. My bad. During the initial examination, I could not find the SQL * Plus for Windows (sqlplusw.exe) in the Oracle11g Client installation or the other.

  Could always try installing with Oracle10g customer or Oracle10g Express Edition.

  Had heard some comments awhile back that SQL * Plus for Windows would disappear at some point, but do not think that was going to be to 11g of product.

  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.

  Thank you

• A question on the impact of SQL * PLUS SERVEROUTPUT Optionconcernant v$ sql

  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.

• 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)

  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.

  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.

• 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 launch SQL * Plus with / nolog

  What is the difference between from SQL * as in
  
  sqlplus sys as sysdba
  
  compared to
  
  sqlplus/nolog
  Connect sys as sysdba
  
  I can imagine that the second method prevents some log writing, but sometimes newspapers are useful. Is there more than that?
  
  Thank you
  Gregory

  / nolog does mean no logon, not no record.

  One of the reasons to start sqlplus with / nolog is to hide the BONE connection credentials.
  For example if you launch sqlplus with login as

  sqlplus test/test@rman
  
  if someone do ps. he will see
  
  ps -ef|grep sql
    oracle 29455  9100  0 09:32:55 pts/3    0:00 sqlplus test/test@rman
  
  If you embedding the login into your SQL script and
  start sqlplus with /nolog,
  ps will only show
  
    oracle 29460  9100  0 09:33:14 pts/3    0:00 sqlplus /nolog

  How to connect sql database to esxi to save all data from the virtual machine

  Please provide steps

  In simple terms, you cannot connect ESXi to SQL. Connect a vCenter SQL (Windows only).

  If you want to save all the data that is contained in your virtual machines, I suggest a backup solution.
