Formatting problem using SQL*Plus Worksheet

Hi!
I would like to format values in a column. It is stored in the database as 'C' or 'F' or 'I'
and I would like to see 'Corporate', 'Foundation' and 'Individuals' in my report.
What is the command to "mask" these values into the values I would like to see?
Thanks!

Thanks, it works fine, just one more thing: the column formatting doesn't work any more...
column dt format a15 heading 'Donor Type'
column pn heading 'Program'
column amount format 9999999999 heading 'Contributions|This Quarter'
SELECT decode(dt,'C','Corporate','F','Foundation','I','Individual','Unknown'), pn, amount from a10;
So it displays 'decode(dt' instead of 'Donor Type'
It seems that the first line has no effect on the decoded column...

Problem running SQL PLUS in Oracle 8i and 9i on Windows XP

I've tried installing both Oracle 8.17 Personal Edition and also 9i in Windows XP Professional (each on a different occassion). I have run into the same problem each time. The installation itself goes fine in both cases, but when I run SQL PLUS, the Log On screen appears for 1-2 seconds then whole thing just closes automatically, so I can't ever access that application which is the only thing I need to work with. Any ideas on what's going wrong? Thanks.

Patrick,
Well a few things. Did you try TNSPING to see if the listener is up? If it's ok, can you connect with FREE toad? Download Oracle OEM and install that (the SQL net and sql plus portions). If you can't get tnsping to work, sqlplus isn't going too either. I don't know why the sqplus is actually shutting down, but I'm guessing the TNS NAMES entry isnt there (in the tnsnames.ora file). If the tnsnames entry is there then tnsping should work. Get tnsping to work first.

Problem with SQL Plus

I'm getting started with Oracle.
I've just successfully installed Oracle 11g. When I opened SQL plus, and tried typing a statement SELECT SYSDATE FROM dual, the answer display is : 2 .
Then i tried with SELECT 2*6 FROM dual, and it still appeared with 2.
I'm really confused.
Plz explain it to me. Thanks in advance.
Edited by: user13011143 on Apr 24, 2010 1:10 AM

Is this what you are seeing?
SQL> select sysdate from dual
2 If so put a semi-colon at the end and hit the Enter key.
SQL> select sysdate from dual
2 ;
SYSDATE
24-APR-2010 03:28:13
SQL>or more properly:
SQL> SELECT sysdate FROM dual;
SYSDATE
24-APR-2010 03:29:10
SQL> The semicolon is not optional.

Seek help to format spool file from SQL*PLUS

I am running a Unix shell script to call a Oracle 11g SQL script from a Oracle database. In this SQL script, I need to connect to many different remote databases to select data, then sool these records as one big text file to a directory. Then email the file to related Group users. In the spool file, there is a line on the top of each page like this:
DUMMY
DB_NAME
I know this is caused by connect to remote database in SQL*PLUS. My connection string is like this:
Conn system/password@Oracle_SID
How can I remove these lines or how to skip these lines into spool file? Please advise. Thanks in advnce. Wish all of you Happy New Year!!!

Hi,
It sounds like you have some kind of formatting (such as SQL*Plus TTITLE) producing the output you don't want. If that's the case, temporarily stopping the spooling might not help you. Find out what is causing the output that you don't want. You say that you know it is caused by the CONNECT statements, but it must be more than that. I've written scripts with CONNECT statements that don't have anything like what you reported at the top of each page; in fact, they don't even have pages: the output is one continuous stream. Find out what's putting the unwanted output there, and that will be a big clue as to how you can stop it.
You say that you know the unwanted titles are there because of the CONNECT statements. If so, use database links instead of CONNECT. You don't have to use dbms_scheduler or utl_file; just eliminate the CONNECT statements. (I'm not saying that there's anything wrong with dbms_scheduler or utl_file; you should definitely investigate those tools. I'm just saying that using database links is independent of them.)
What would happen if you did all your connecting to different databases at the OS level? Can you write a shell script that connects to each database in turn, and runs a SQL*Plus script in each one. Each SQL*Plus script would have a SPOOL or SPOOL ... APPEND command, or maybe you could build the SPOOL into a LOGIN.SQL script.

SQL*Plus Worksheet formating

I have Oracle Client 8.1.7 installed in my computer, and I can't
seem to have the desired output format with the SQL*Plus
worksheet.
I have a database where the tables have several column, and most
of these columns are text with 1024 characters length. I set the
linesize to a huge number (say 3000), the trim and trimspool on,
and I get the results ok.
But, when I want to do a select from a table which is much
smaller, the worksheet is always writing the complete linesize...
Is there a way to display the columns according to the size they
actually have (e.g. defined by the longest element) that is
always valid. I mean without having to set column options for
each table.
Thank you in advance.
Ana

The column width sizing rules are a little opaque. The column size is a function of things like the width that the DB thinks the column is (could be huge if a SQL function is being selected), the column name or heading width, the linesize (for very wide columns), any global format (e.g. SET NUMWIDTH), or the explicit COLUMN FORMAT.
For consistency and portability I'd always recommend using an explicit COLUMN FORMAT. You can never tell if someone is going to run your report after previously setting a COLUMN FORMAT of the same name. Or a new database version may come out where the default datatype of a SQL function has changed. In the past this has happened when CHARs became the longer VARCHAR2s.
I don't think Enterprise Manager's SQL Worksheet (a simplistic interface that just calls SQL*Plus in the background) is doing anything special for formatting. So COLUMN FORMAT will work fine.

Sql Plus and Unicode (or utf-8) characters.

Hello,
i have problem with Sql Plus and unicode files. I want to execute Start {filename}, where {filename} is file in unicode format (this file have to contains german and polish characters). But i receive error message. It is possible to read from unicode (or utf-8) file and execute commands from this file)?

Unable to connect to an instance using EM but connecting fine with SQL*Plus

Good morning,
I followed these steps (from the 2 Day DBA document):
1. I created a template (including database) from an instance named "orcl" using DBCA, before proceeding to create the template, DBCA informed me that the instance would be shutdown, I told it to proceed.
2. The template was created successfully.
3. I am now unable to log into the orcl instance using EM, yet I can log into that instance without any problems using SQL*Plus.
The Question: Why am I not able to connect to the instance using EM ? and what do I need to do to correct this problem ?
Thank you very much for your help,
John.

SQL *PLUS issue

I have an unusual problem in SQL PLUS. When the SQL statement is a DML things go fine - no problem, BUT when the SQL statement is a DDL (like creating a database object )the process hangs. Things get more interesting ... if I open another SQL PLUS session and check out, I find that the DDL has done its task. But the first SQL session (where I issued the DDL) is still hanging. If anyone has any idea please do let me know. Any help would be very useful
Thanks
Mustafa

The dot is used as like concatenation operator in sqlplus. If you need to add characters to the end of the variabel, you use a dot. If you need to add .chars then you need two dots.
With a dot
SQL> SELECT 'Say &something.not' FROM dual;
Enter value for something: something
old   1: SELECT 'Say &something.not' FROM dual
new   1: SELECT 'Say somethingnot' FROM dual
'SAYSOMETHINGNOT

SQL*Plus Not responding when calling edit command

When I write a Query in SQL Plus 9.2.0.1.0, Installed in Windows XP SP2, and running EDIT command, notepad opens and then SQL Plus and Notepad both hangs. By killing notepad.exe process I can continue working in SQL Plus.
I tried changing the default editor to ultra edit, wordpad, etc. But It seems to be a SQL Plus error, with all editors I set up, Editor Hangs.
The same things happende me installing the Oracle 9i client in another machine.
Need help with this, thanks!!

Sounds strange - and does not sound like a SQL*Plus problem. SQL*Plus uses the CreateProcess() Win32 API call to create the editor process. Then it waits for this process' process handle to cease to exist before it continues. SQL*Plus does not "hang" - it simply waits for the spawned process to terminate before it continues.
It is not possible for one process to "hang" another process it created via the CreateProcess() call. It will need to interact with that spawned process in other ways to make it hang. Caveat: unless the spawned process does not "like" the parameters passed to it via the CreateProcess() call...
The only parameter passed is the filename (usually afiedt.buf) by SQL*Plus - and that should not cause the editor to hang.
Unless there is a specific Oracle bug you're running in, this problem sounds more like a Windows issue. After using the ED command in SQL*Plus, can you manually view and edit the afiedt.buf file it created?

SQL Plus not work with domain user

Hey guys,
have a problem with sql plus in our network. when i started it with the admin it works. but when i started it with a user account, fill in the username, the password and the host and click on the ok button, the window closes and nothing happen. no error no new window, the window simply closes.
what to do?
regards

Hi,
There might be different reasons behind this.
Check whether user is created in database or not.
There might be possibility that, user is in different database.
SELECT * FROM V$DATABASE; --This will help you to findout database name.
SELECT * FROM DBA_USERS WHERE USERNAME = 'HR'; --HR is user present on database. If your user is present in database then user might not have connect privilege.
GRANT CONNECT , RESOURCE TO HR; --HR is user. To execute this command, login as sys You can also try to login with command prompt.

XMLType is automatically formatted in SQL*Plus 9.2. But, how can I format it on SQL*Plus 9.0.1? Now I only obtain tuples like XMLTYPE().

Oracle DS is not the proper software for this purpose, take Oracle 9i client CD instead.

SQL*PLUS mouse scroling not working..

Hi,
I am facing one problem in SQL*Plus tool, and couldn't find solution. Please help me.
I have set the line size 9999. When i select the data from table (or dual) which is having more line size that the screen size, some of the part is displayed on screen that the rest have been cut. I cannot scroll the screen horizontally to see the rest part of the output. If i set the line size 80, the whole output is displayed in wrapped style.
Is there any other configuration or settings i need to do.. Please let me know what i am missing..
Regards,
Dipali.

Aman, Amar and Jaffy,
Thanks for your reply.
Aman, yes dear, i can use DOS prompt, but i am using SQL*Plus tool and facing problem it. Instade of looking for alternative i want to solve this problem.
Jaffy, i go through the index of the book given in the link by you. But didn't find the topic related to my problem.
Aman, I tried to increase the screen buffer size from environment dialogue box. When i tried for first time, i was asked to disconnect from database. I did that, increased the buffer width to 10000 and keep the lenght untouchd (1000) and set the line size to 9999. Then i connected to DB and checked it and i got what i wanted :).
But when i tried for next time, i was not getting that..It was behaving strange.. when i set the buffer size 10000, it showed message that 'screen buffer lenght must be between 80 to 1000' and when i set it to 1000 it showed 'screen buffer lenght must be between 80 to 2000' !!!!
I am still trying.....
Thank you.. :)

Does SQL Plus recognize any type of newline character from DBMS_OUTPUT?

I am building a complex string inside a procedure and displaying with dbms_output.put_line. It works fine in SQL Developer but when I use it in SQL Plus it comes out goofy. It's been narrowed down to me using CHR(10) where I want line breaks. Is it possible to display a "formatted" varchar2 in SQL Plus as I'm expecting them? I even tried using .put with no luck.
Using:
Oracle 10.2.0.4.0
SQL Plus 10.2.0.1 / 9.2.something
Here's a small example:
set serverout on
set linesize 10
declare
lv_string varchar2(32767);
begin
for x in 1..5
loop
    lv_string := lv_string || 'I AM LINE ' || to_char(x) || chr(10);
end loop;
dbms_output.put_line(lv_string);
end;
Expected Output (What I'm getting in SQL Developer):
I AM LINE 1
I AM LINE 2
I AM LINE 3
I AM LINE 4
I AM LINE 5
Actual Output (SQL Plus):
I AM LINE
1
I AM
LINE 2
I
AM LINE
3
I AM
LINE 4
I
AM LINE 5Right now I'm using a workaround, but would like to use a character (or combination of character) that SQL Plus will play nice with...if there are any.
declare
lv_string     varchar2(32767);
lv_start      pls_integer;
lv_end        pls_integer := 0;
c_newl        constant varchar2(1) := chr(10);
begin
for x in 1..200
loop
    lv_string := lv_string || 'I AM LINE ' || to_char(x) || c_newl;
end loop;
loop
    lv_start := lv_end + 1;
    lv_end := instr(lv_string, c_newl, lv_start);
    exit when lv_end <= lv_start;
    dbms_output.put_line(substr(lv_string, lv_start, lv_end- lv_start));
end loop;
end;

Hi,
you need to increase your linesize:
SQL> declare
2    lv_string varchar2(32767);
3 begin
4    for x in 1..5
5    loop
6      lv_string := lv_string || 'I AM LINE ' || to_char(x) || chr(10);
7    end loop;
8    dbms_output.put_line(lv_string);
