Friends,
when i set the linesize above 200 the result is going out of my 17inch monitor. but when i set the linesize to 100 its displaying correctly. This linesize i tested with the "desc tablename"
here is the output....

Strange error in sql*plus in a line with "&"

Hi friends, this error is very strange:
Open your SQL*PLUS.
write this:
DECLARE
V_1 VARCHAR2(10);
V_2 VARCHAR2(10);
BEGIN
V_1:=&var1;
--V_2:=&var2;
END;
Why it ask me for a value to var2 ???????????
Does it ignore the -- at the begining of the line
(same result with /* */ )
Thanks,
Jose.

It is not an error.
There are two parsers here doing their thing. The SQL*Plus Parser. The Oracle (SQL and/or PL/SQL) parser.
SQL*Plus reads a line at a time and processs it. It has no idea whether or a line is actually a comment line for SQL or PL/SQL. It however does see that the line contains a SQL*PLUS substitution variable called &var2. Thus it prompts for a value for this variable (as VERIFY is ON). It substitutes &var2 with the value that the user supplies.
When the SQL*Plus parser encounters the end-of-block marker (the forward slash in this case), it transmits that block to the Oracle Server for execution. There the Oracle Server runs it through the PL/SQL or SQL parsers (depending on whether the block is SQL or anonymous PL/SQL).
Nothing strange about it. Nothing wrong with it.

Hi, i've found this strange behaviour:

Hi, i've found this strange behaviour:
if i open a pdf file from a pen drive, and after i try to print it, i have the message: You need to install a printer......
then if i copy the same file to the hdd, then i open this file and print it, now i can print !!
this happen with the reader 8.2.4, so i've update to the new X version and nothing is changed.
i use XP sp3 with hp 6280 all-in-one
someone can explain and resolve it?
thank's
Giorgio

Well, no it probably won't work because the phone is locked so there is nothing you can do.
You won't be able to activate it, so you might never be able to use it.
You have been dishonest here and if you found a phone, then someone had obviously lost it, so you should have handed it in to the police rather than keeping it for yourself.
You probably won't be able to use the phone because it sounds like the phone is locked to the carrier in Muaritius and if you don't own the phone and don't have a contract, then that carrier will problably not unlock the phone for you, so you now have a paperweight that you can't use.
You get no help here for dishonest practices and you won't be able to activate or use that phone.

Different behaviour in SQL*Plus and PL/SQL

Does anyone know why the following SQL works from the command line in SQL*Plus but results in a syntax error when included within a cursor in a PL/SQL procedure?
SELECT (SELECT 'dummy' FROM dual)
FROM dual;
null

Is this what you require? This works...
declare
cursor cur_dummy is
SELECT d.dum
FROM (
SELECT 'dummy' dum
FROM dual
) d
v_dummy varchar2(30);
begin
open cur_dummy;
fetch cur_dummy into v_dummy;
close cur_dummy;
dbms_output.put_line(v_dummy);
end;

Why this strange CallResponder behavior?

Perhaps someone can help me figure out why calling "catSelectionChangeHandler()" below sets "restaurants" (the ArrayCollection) equal to "selectedRestaurants". I am confused because "restaurants" is only supposed to be affected by the "getAllRESTAURANTResultHandler()" method.
Can you see where the problem is, or is it somewhere in the code I haven't included?
        private function initApp():void
            getAllRESTAURANTResult.token = rESTAURANTService.getAllRESTAURANT();
        // The list of all the restaurants
        public var restaurants:ArrayCollection;
        // The restaurants matching the user's selection
        [Bindable]
        private var selectedRestaurants:ArrayCollection = new ArrayCollection();
        private function getAllRESTAURANTResultHandler(event:ResultEvent):void
              restaurants = event.result as ArrayCollection;
              selectedRestaurants = restaurants;
              // add stuff to a datagrid here
        private function catSelectionChangeHandler(selectedCategories:ArrayCollection):void
                getRESTAURANTSByCATEGORIESResult.token = rESTAURANTService.getRESTAURANTSByCATEGORIES(selectedCategories.toString());
        private function getRestaurantsByCategoriesResultHandler(event:ResultEvent):void
                selectedRestaurants.source = ArrayUtil.toArray(event.result.source);
Here are the relevant MXML declarations:
<restaurantservice:RESTAURANTService id="rESTAURANTService" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
    <mx:CallResponder id="getAllRESTAURANTResult" result="getAllRESTAURANTResultHandler(event)"/>
    <mx:CallResponder id="getRESTAURANTSByCATEGORIESResult" result="getRestaurantsByCategoriesResultHandler(event)"/>

Why "exp" is invalid in SQL*Plus (Oracle 9i)

When I run "exp ... " in SQL*Plus(Oracle 9i),why did it say "Unknown Command 'exp'..."??

exp is not a SQL or SQL*Plus command. It is an application that can be invoked at the command line of your operating system.

Strange behaviour of sql loader

Hi Experts,
Enivroment Details:
database : Oracle Database 11g Enterprise Edition Release 11.2.0.2.0
OS : Solaris 10
We are having problems with inserting data into a table using sqlldr. Here is how we use sqlldr.
We get csv files to a location in the database server. then we use sqlldr through a shell script to load the data one file after the other. This has been running since months. For the past few days every load is failing leaving some paritally processed csv files. When I checked the logs I see that those records are rejected with the error ORA-01861: literal does not match format string.
But when I run the sqlldr for the records in bad file seperately, they are getting inserted into the table properly.
The sqlldr control file has the following columns.
LOAD DATA
append into table my_table
fields terminated by '|'
trailing nullcols
DATAFILE_NAME,
DATAFILE_TIMESTAMP timestamp(3) 'YYYYMMDDHH24MISS.ff',
DATA_RECEPTION_DATE timestamp(3) 'YYYYMMDDHH24MISS.ff',
The table structure is as follows
DATAFILE_NAME Varchar2(200 char)
DATA_FILE_TIMESTAMP TIMESTAMP(9)
DATA_RECEPTION_DATE TIMESTAMP(3)
Do any one have idea why it is happening.
Thanks in advance

That comparison is not enough - pl modify the shell script to show the actual run time environment variables (use "set -x") and then compare to the environment variables with the manual run.

Why this odd behaviour with radio?

If I select 'Martini in the Morning' internet radio I get an error message. It just won't work. If I select a station one or two above in the list, tune in, then jump forward I get Martini just fine. Why? Can I fix it?

Have you tried clearing the Safari cache and Java
Plugin Settings caches?
Looks like that was the problem! Thanks!

Why SQL Plus?

Why Oracle People give us SQl Plus?.
Why not something like SQL Navigator or MS Query Analizer?.
SQL Plus is so terrible, is like MS-DOS.

Well, maybe because SQL Navigator is not their product (would it not be nice if Oracle could bundle this as a free goodies with the database license) and Last I checked, MS Query Analizer would work against that other database (not against Oracle), but again I might not have the correct/complete information (also not a Oracle product).
As for asking Oracle to provide comparable tools, well you have SQL Worksheet (for people who want GUI interface) or the OEM. Other host of tools provided would allow you to manage and tune your database.

Strange behaviour of Removal of Alpha for Info object in Quality system

Strange behaviour of Removal of Alpha for Info object in Quality system as compared to Development system.
Hi,
The data for an info object Key in the DSO was 00000000000000000000000000123. I removed Alpha for the info object and data was corrected to 123 in the DSO in development system.
Now, when i transported the info object without alpha to quality and loaded data into DSO, the data is still the same with leading zeros.
I dont want to write routine to remove leading zeros, as I have values as 0. If i write routine, all zeros will be removed and this will be blank.
Both development and quality have same patches applied and are on same level.
Why is this strange behaviour in quality system...
Any inputs?? please suggest.
Thanks.

Hi,
Did you drop and reload the data after changing the conversion?

How to delete duplicates in oracle 10g ( strange behaviour)

Recently we migrated from oracel 8i to oralce 10g and we face this problem.
When we try to delete duplicates using rowid ( analytical functions row_number()/
or normal delete ) and commit the same , still we find some duplicates to be existing because of which we are not able to enable costriants and resulting in process failure.
When we run the same delete statement next time it removes more duplicates than the required or sometimes required duplicates resulting in abnormal behaviour.
I don not understand this strange behaviour after upgrading to oracle 10g.
It'd be great if some one who has idea on this can throw light on the same.
thanks

Code runs correctly when compiled by SQL developer but not SQL Plus

I have a rather large package body I need to deploy and compile ... It's big and complex (I inherited the project). Our it dept is huge and scripts are deployed by the dba team and they seem to only use sql plus. My code deploys and runs fine when compiled in sql developer. Once I compile it from SQL plus it stops working. It runs and using debug statements I can see the values are correct but it no longer inserts the data into the proper tables. I get ZERO errors or warnings when this is compiled in SQL Plus and no errors are generated from the code at run time. I've diffed the extracts of the code from the DB after each deployment and the only difference is the blank lines which SQL Plus strips out when you load the file. Has anyone run into anything remotely similar and if so how did you solve it? I've tried modifying the code to no avail, adding in comments to preserve the white space makes no difference. The thing that really kills me is that there is no error at all.

Ok this is the problem area.... vReplyMessage is a clob. I've replaced it in this section of processing with a varchar2(32000). And now it works. I still would like to know why though. Nothing is changed when I load it though sqlplus or sql developer but this line " update swn_recip_response_t set SWN_RECIP_RESPONSE = vTextReply where notification_id = v_notification_id; " would never execute with the clob. Logging showed that the clob had the correct value though. I am puzzled.

SQL*Plus/iSQL*Plus login as DBA

I just installed 10g Enterprise on a Windows platform and am a bit confused to why I cannot log into SQL*Plus/iSQL as a DBA. I can login as one of the user accounts then use 'connect' to login as dba in SQL*Plus or at the Windows command prompt. I cannot do this, however, in iSQL*Plus. One of the threads on this forum pointed me to using JAZN after installing OC4J. I am in the process of doing this, but I need to understand something apparently fundamental: why should I have to perform another install when the Universal Installer installed iSQL and all the features that came with it? Didn't the 10g download give me the tools necessary to administer its application's accounts? The OC4J download page states that this tool should not be used to replace an existing 10g installation.
Moreover, why iSQL knows about the 'users' authorization level, but not 'system?' I can see the users and groups in the Enterprise Manager, but no features to set WebDBA users as iSQL*Plus requests.
Your comments would be much appreciated.

Hi,
in order to use iSQL*Plus as DBA, you have to perform additional configuration. See
http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/ch2.htm#BCEIHEJF
By the way: Get used to a different tool like SQL*Plus linemode or SQL Developer, because iSQL*Plus disappears in future versions.
Kind regards
Uwe

Facing Strange Behaviour in WD

Hi,
I am developing the WD application.
But am facing Strange Problem.
When i am writing code for inserting data in wdDoInit() method it is successfully inserting data. I am also calling executeInsert() method and in that i have executed the modelobject. In InsertView i have called the executeInsert method using wdThis.<ComponentController>.executeInsert();
But when i write the code in method executeInsert() which i have created then it is not inserting in database.
and then calling it in insertview as wdThis.<ComponentController>.executeInsert();
So i am not able to understand this Strange Behaviour.
Pls explain me why this happens...
Thanks & Regards,

Hi,
public void wdDoInit()
    //@@begin wdDoInit()
    try
         Zep_Events_Input inp = new Zep_Events_Input();
         wdContext.nodeZep_Events_Input().bind(inp);
          inp.setAdd1(wdContext.currentZep_Events_InputElement().getAdd1());
                         inp.setAdd2(wdContext.currentZep_Events_InputElement().getAdd2());
                         inp.setBukrs(wdContext.currentZep_Events_InputElement().getBukrs());
                         inp.setButxt(wdContext.currentZep_Events_InputElement().getButxt());
                         inp.setDisp_Mod(wdContext.currentZep_Events_InputElement().getDisp_Mod());
                         inp.setE_Date(wdContext.currentZep_Events_InputElement().getE_Date());
                         inp.setE_Name(wdContext.currentZep_Events_InputElement().getE_Name());
                         inp.setLocation(wdContext.currentZep_Events_InputElement().getLocation());
                         inp.setStatus(wdContext.currentZep_Events_InputElement().getStatus());
    catch(Exception e)
         wdComponentAPI.getMessageManager().reportSuccess(e.toString());
//@@begin javadoc:executeInsert()
/** Declared method. */
//@@end
public void executeInsert( )
    //@@begin executeInsert()
          try
//               Zep_Events_Input inp = new Zep_Events_Input();
//               wdContext.nodeZep_Events_Input().bind(inp);
              wdContext.currentZep_Events_InputElement().modelObject().execute();
          catch(Exception e)
               wdComponentAPI.getMessageManager().reportSuccess(e.toString());
    //@@end
public void onActionSave(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionSave(ServerEvent)
    //$$begin ActionButton(-1900911611)
    wdThis.wdGetActivityController().executeInsert();
    //$$end
    //@@end
Now if i write following way then i am not able to insert data:
public void wdDoInit()
    //@@begin wdDoInit()
    try
         Zep_Events_Input inp = new Zep_Events_Input();
         wdContext.nodeZep_Events_Input().bind(inp);
    catch(Exception e)
         wdComponentAPI.getMessageManager().reportSuccess(e.toString());
public void executeInsert( )
    //@@begin executeInsert()
          try
//               Zep_Events_Input inp = new Zep_Events_Input();
          inp.setAdd1(wdContext.currentZep_Events_InputElement().getAdd1());
                         inp.setAdd2(wdContext.currentZep_Events_InputElement().getAdd2());
                         inp.setBukrs(wdContext.currentZep_Events_InputElement().getBukrs());
                         inp.setButxt(wdContext.currentZep_Events_InputElement().getButxt());
                         inp.setDisp_Mod(wdContext.currentZep_Events_InputElement().getDisp_Mod());
                         inp.setE_Date(wdContext.currentZep_Events_InputElement().getE_Date());
                         inp.setE_Name(wdContext.currentZep_Events_InputElement().getE_Name());
                         inp.setLocation(wdContext.currentZep_Events_InputElement().getLocation());
                         inp.setStatus(wdContext.currentZep_Events_InputElement().getStatus());
               wdContext.nodeZep_Events_Input().bind(inp);
              wdContext.currentZep_Events_InputElement().modelObject().execute();
          catch(Exception e)
               wdComponentAPI.getMessageManager().reportSuccess(e.toString());
    //@@end

Why this strange behaviour in sql*plus linesize?
