SQL*Plus: Comment appears in Default-Column

Please look at this commands, executed in SQL*Plus (Oracle 10g):
create table t1 (
c1 number,
c2 number default 0 -- comment in sqlplus
select column_name,data_default from all_tab_columns where table_name='T1';
COLUMN_NAME                    DATA_DEFAULT
C1
C2                             0 -- comment in sqlplus
The comment is stored in the data dictionary! ?:|
insert into t1 (c1) values (0);
commit;
But the default clause works:
select c1,c2 from t1;
C1        C2
+0 0+
Is it a bug or is it a feature???

SQL * PLUS - setting wrap on for column

hi all, i am playing around with sql plus and i encountered the following problem.
1) is length 10 the default column length for columns with number datatype in sqlplus, i done a select statement and all my column for number have a length of 10
2) why cant i format the length of a number column. i type column empno format 999
although my numbers become #### but "empno" and a length of 10 is still shown at the column name instead of just "emp"
3) how come a column name canot be wrapped
when i set wrap on.
set wrap on
column ename format a3
only the values of ename are wrap
but the column name "ename" isnt wrap
into ena
me
thanks.

Some examples :
TEST@db102 > select 1234567890123 from dual;
1234567890123
1.2346E+12
TEST@db102 > set numwidth 15
TEST@db102 > /
1234567890123
1234567890123
TEST@db102 > col ename for a3 wrapped
TEST@db102 > select ename from emp where empno=7902;
ENA
FOR

SQL*Plus variable assignment works for 8i but not 9i

We have scripts that connect to each database on the box and perform database tasks nightly. The scripts first set the environment then connects to each database with SQL*Plus. This works for 8i but fails in the recently created 9i environment. (Unix Solaris environment)
Because the SQL*Plus connection appears in many areas in the scripts, we assign the following connection string to a variable:
SQLPLUS="/usr/oracle/product/9.2.0/bin/sqlplus -s 'xxx/xxxxxx@xxxx as sysdba'"
Export SQLPLUS
echo "$SQLPLUS"
(This echo out correctly: /usr/oracle/product/9.2.0/bin/sqlplus -s 'xxx/xxxxxx@xxxx as sysdba')
It fails when the script calls the assigned variable:
$SQLPLUS <<-EOF
with the following error:
Usage: SQLPLUS [ [<option>] [<logon>] [<start>] ]
where <option> ::= -H | -V | [ [-L] [-M <o>] [-R <n>] [-S] ]
<logon> ::= <username>[<password>][@<connect_string>] | / | /NOLOG
<start> ::= @<URI>|<filename>[.<ext>] [<parameter> ...]
"-H" displays the SQL*Plus version banner and usage syntax
"-V" displays the SQL*Plus version banner
"-L" attempts log on just once
"-M <o>" uses HTML markup options <o>
"-R <n>" uses restricted mode <n>
"-S" uses silent mode
However, if I remove the SQLPLUS variable assignment and changed all occurrence of
$SQLPLUS <<-EOF to
/usr/oracle/product/9.2.0/bin/sqlplus -s 'xxx/xxxxxx@xxxx as sysdba' <<-EOF
Then the script runs successfully. But this solution is cumbersome.
Any ideas as to how to have the script work with assigning the SQLPLUS variable????
Any help is appreciated.

I has an immediate suspicion it might be related to the issue
mentioned in
http://otn.oracle.com/support/tech/sql_plus/htdocs/sub_var2.html#2_7
but this proved wrong: the SP2-306 still occurs in the latest
SQL*Plus.
I wonder what version of 8i you had working? With an old SQL*Plus
8.1.7.0 my connection failed the same as in 9.2 and 10i.
My solution was to do:
SQLPLUS='sqlplus -s'
UNPW='/ as sysdba'
$SQLPLUS "$UNPW" <<EOF
EOFThis worked in 9.2.0.5, 10.1.0.2 and 8.1.7.0.
One common security risk on UNIX remains: putting the username and
password on the command line. On some systems a "ps" command will
show the password to any user. If OS authentication cannot be used
for connection, perhaps putting the username/password in the SQL
script may be more secure?
A final note is that in SQL*Plus 10g, no quotes are needed around
AS SYSDBA, i.e.
sqlplus / as sysdba works from the OS prompt, whereas in 9.2 you need to do
sqlplus "/ as sysdba"This makes a solution easy:
SQLPLUS="/usr/oracle/product/10.1.0/bin/sqlplus -s xxx/xxxxxx@xxxx as sysdba"-- CJ

Sql plus password typing problem

Hello there
I'm trying to access sql plus 11g on windows 7, i correctly write the username but when i try to type the password, nothing is typed at all, not letters nor asteresks!!
plz help meee

C:\Users\lord>sqlplus / as sysdba SELECT * V$VERSION;
SQL*Plus: Release 11.2.0.3.0 Production
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Use SQL*Plus to execute SQL, PL/SQL and SQL*Plus statements.
Usage 1: sqlplus -H | -V
-H Displays the SQL*Plus version and the
usage help.
-V Displays the SQL*Plus version.
Usage 2: sqlplus [ [<option>] [{logon | /nolog}] [<start>] ]
<option> is: [-C <version>] [-L] [-M "<options>"] [-R <level>] [-S]
-C <version> Sets the compatibility of affected commands to the
version specified by <version>. The version has
the form "x.y[.z]". For example, -C 10.2.0
-L Attempts to log on just once, instead of
reprompting on error.
-M "<options>" Sets automatic HTML markup of output. The options
have the form:
HTML ON [HEAD text] [BODY text] [TABLE text]
[ENTMAP {ON|OFF}] [SPOOL {ON|OFF}] [PRE[FORMAT] ON]
-R <level> Sets restricted mode to disable SQL*Plus commands
that interact with the file system. The level can
be 1, 2 or 3. The most restrictive is -R 3 which
disables all user commands interacting with the
file system.
-S Sets silent mode which suppresses the display of
the SQL*Plus banner, prompts, and echoing of
commands.
<logon> is: {<username>[<password>][@<connect_identifier>] | / }
[AS {SYSDBA | SYSOPER | SYSASM}] [EDITION=value]
Specifies the database account username, password and connect
identifier for the database connection. Without a connect
identifier, SQL*Plus connects to the default database.
The AS SYSDBA, AS SYSOPER and AS SYSASM options are database
administration privileges.
<connect_identifier> can be in the form of Net Service Name
or Easy Connect.
@[<net_service_name> | [/]Host[:Port]/<service_name>]
<net_service_name> is a simple name for a service that resolves
to a connect descriptor.
Example: Connect to database using Net Service Name and the
database net service name is ORCL.
sqlplus myusername/mypassword@ORCL
Host specifies the host name or IP address of the database
server computer.
Port specifies the listening port on the database server.
<service_name> specifies the service name of the database you
want to access.
Example: Connect to database using Easy Connect and the
Service name is ORCL.
sqlplus myusername/mypassword@Host/ORCL
The /NOLOG option starts SQL*Plus without connecting to a
database.
The EDITION specifies the value for Session Edition.
<start> is: @<URL>|<filename>[.<ext>] [<parameter> ...]
Runs the specified SQL*Plus script from a web server (URL) or the
local file system (filename.ext) with specified parameters that
will be assigned to substitution variables in the script.
When SQL*Plus starts, and after CONNECT commands, the site profile
(e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile
(e.g. login.sql in the working directory) are run. The files may
contain SQL*Plus commands.
Refer to the SQL*Plus User's Guide and Reference for more information.

SQL Plus Crashes.

If I mistype a query in the SQL Plus window (say a wrong column name) it crashes.
This is happenning with my new installation of Oracle8i 8.1.7 EE on Windows 2000 Pro.
Any Ideas?
Thanks.

It's not possible to connect from 10g to 7.3.4, but it works until client version 9.2.0.

Question about setting column width in SQL*Plus using info retrieved w SQL

Good morning,
Is there a way to tell SQL*Plus to set the width of a column to the greatest width of the elements found in the column ? (as opposed to the default which is the width declared in the DDL)
In other words, I'd like to do something functionally equivalent to this:
COL <columname> format a[select max(length(<columnname>)) from <thetablethatcontainscolumname>]
I'm doing the above manually in two steps
1. select max(length(columnname)) from .....
2. col columnname format a[resultofstep1]
Is there a way of doing it in one step ?
Thank you for your help,
John.

Hi Munky,
>
you should consider whther you are using the correct tool for the job, SQLplus isn't exactly ideal for doing presentation layer stuff
>
I'm not really doing presentation stuff, I asked because it would be very convenient for everyday stuff. I commonly query the tables that I am going to deal withm just to have a look at the column names and a few values, something like:
select * from EMP where rownum <= 10; -- just to have a look at the table and some values
when the table contains a wide column then the display gets all messed up. It would be nice to have an option or a mechanism to tell SQL*Plus to automatically use the width of the widest value, instead of having to determine the value and then manually set the column.
thank you for your help, it's good to know that I didn't miss some trivial setting in the documentation that would do it ;)
John.

Plsql developer probably issue something like this in the background:
select col.column_name,data_type,nullable,data_default,comments
from all_tab_columns col,all_col_comments com
where col.table_name=com.table_name
and col.owner=com.owner
and col.column_name=com.column_name
and col.owner='SYS'
and col.table_name = 'USER_EXTENTS'You could save similar code in script in your SQLPATH and pass the object that should be described via substitution variable.
There are really [url http://www.adp-gmbh.ch/blog/2005/september/25.html]interesting approaches on the net regarding describe customization.

How to change the default directory from within SQL*Plus ?

Hello,
I want to change the default directory directly from within SQL*Plus to be able to launch my command files with simple instructions like :
@my_command.sql
If I haven't launched SQL*Plus from the directory containing the file my_command.sql, how do I change the default directory to the directory of my command files ?
I've searched through the Oracle documentation, there's no SET DEFAULTDIR or something like that. When I do a SHOW ALL, there's no variable containing the default directory.
If you have an idea...
regards,
Jérôme.

Hi JÃ©rÃ´me (Jé²´me ?),
You cannot directly do that, but you can use @@ instead of @ to run subscripts in the same directory as the superscript
# head /tmp/tl30/xxx/[xyz].sql
==> /tmp/tl30/xxx/x.sql <==
prompt call y
@y
prompt call z
@@z
quit
==> /tmp/tl30/xxx/y.sql <==
prompt i am in y
==> /tmp/tl30/xxx/z.sql <==
prompt i am in z
# pwd
/root
# sqlplus -s scott/tiger@lsc62 @/tmp/tl30/xxx/x.sql
call y
SP2-0310: Datei "y.sql" konnte nicht geÃ¶ffnet werden
call z
i am in zKind regards

GREATER THAN symbol appearing as &gt ; in SQL*Plus

Version:11.2.0.3
OS : RHEL 5.4
We are a Software vedor firm.We have sent our SQL files to our client to execute. But the codes for various procedures and functions were failing
because, in their SQL*Plus session (in Putty) the LESS THAN character < was appearing as &lt ; and GREATER THAN character > was appearing as &gt ;
In the original code which we had sent to them has no problems with > or < characters.
Original code
Cursor feb_cur IS
SELECT user_pwid
    FROM carton_hdr_dtl
   WHERE MODIFIED_DATE >= D_Last_Run_Date
   UNION
SELECT user_pwid
    FROM carton_hdr_dtl_bkp
   WHERE (modified_date >= D_Last_Run_Date OR
          deleted_date >= D_Last_Run_Date); But in the execution log file sent by our client, I can see &gt ; instead of > character.
54   Cursor feb_cur IS
55    SELECT user_pwid
56       FROM carton_hdr_dtl
57      WHERE MODIFIED_DATE &gt ;= D_Last_Run_Date
58      UNION
59    SELECT user_pwid
60       FROM carton_hdr_dtl_bkp
61      WHERE (modified_date &gt ;= D_Last_Run_Date OR
62             deleted_date >= D_Last_Run_Date);What are they doing wrong? They use putty. We use putty too but we don't have any issues.

Thank you Blushadow, Nicosa for providing this clue.
I checked with my client. They have put our scripts in Collabnet SVN version control and the implementor DBA will be provided the http URL .
Apparently SVN is accessed using http protocol and yes you are right it is opened through a browser by typing an URL like below
http://10.80.16.214:79839/svn/brcf/DBfiles/2012/WMHReleasel8/hrtb_pkt_wave.sqlFor most of the end users , the GREATER THAN character appears as > without any issues . For some users it appears as &gt ; . One potential cause is the difference in Internet Explorer version. They are currently looking into this.
THANK YOU BLUSHADOW and NICOSA for shedding light on this.
Hi Nicosa,
A forum formatting question:
How did you manage to get &gt_; (without the underscore) printed ? When I tried it the forums editor was converting it to > . This is why I placed a space/underscore between t and semi colon. Is there some escape character ?

Set Column width in query (not using SQL*Plus)

How can I Set Column width in query
I understand you can set column width using
column col1 FORMAT A5
select col1 from table1;But this only works in SQL*Plus
I want to be able to do this in a regular SQL query window (not in SQL*Plus), how can I do it.....
I am using a 'SQL window' in PL/SQL Developer IDE
and when I use this syntax it says:
ORA-00900: Invalid SQL statement
Any suggestions are appreciated...
thanks,
M.

Did you try using RPAD or LPAD functions? They fill the unfilled part of a string with character you provide... either on right or left side depending on what function you use.
e.g.
SELECT RPAD('Smith', 10, ' ') Name FROM dual;http://www.adp-gmbh.ch/ora/sql/rpad.html

X.column.getStringVal() throws "invalid column name", works in SQL*Plus.

The subject sums it up pretty well... I have a query that works fine from SQL*Plus, but throws a JDBC exception with "ORA-00904 invalid column name" if I create a PreparedStatement from it and call executeQuery().
The query itself is substantially similar to:
SELECT foo, t.bar.getStringVal() from some_table t
where "Some table" is an oracle 9i table, "foo" is a varchar2 column, and "bar" is a column that used to be varchar2 before I dropped and re-created the table with an xmltype column instead. "t" is an alias for the table that I didn't used to need (since it's only one table), but apparently is required for getStringVal() to work.
... And, of course, .getStringVal() is being used as a convenient way to treat technically LOB-like xmltype columns as big ersatz varchar2 columns so I won't have to screw around with stream i/o just to read a 4,001-byte value into a String ;-)
I'm using the ojdbc14.jar thin driver and a fairly recent j2sdk (1.4.1_02, I think). I made a point of anihilating every copy of classes12.zip on my PC just to make sure it wasn't lurking in a classpath somewhere to screw things up.
Strangely enough, it DOES work from within Netbeans' database explorer (itself connecting to the same Oracle database using the ojdbc14.jar thin driver).
For the sake of being comprehensive, here's an example of the actual JDBC code that won't work:
public ResultSet doQuery(Connection conn, int val) throws SQLException {
String sql = "SELECT foo, t.bar.getStringVal() from some_table t where anothercolumn = ?";
PreparedStatement sth = conn.prepareStatement(sql);
sth.setInt(1, val);
ResultSet rs = sth.executeQuery();
// everything past this point is moot,
// because sth.executeQuery throws an exception...
// however, the ResultSet would ultimately be
// returned to the method's caller, and
// its values read using getString(fieldname)
// including 'bar', the xmltype field...

OK, this particular problem was my fault. The original table was on a server running 8i. To spare myself the grief of having to deal with CLOBs on 8i's terms and take advantage of 9i's new conveniences for handling them, I created a new table on our other server that's running 9i and updated the app's config settings to reflect the new server. Unfortunately, I forgot that the debugging/testing main() method had the URL of the old database hardcoded (it was written before the rest of the class). Ergo... it was still looking at the old database. Oops. (*blush*).
