Viewing/Identifying blank spaces in SQL*plus

How can i identify blank spaces in Sql*plus? How will i know if the result of the following query has the blank spaces on the right trimmed?
SQL> select rtrim('sxxx ') from dual;
RTRI

Why? This seems a pretty strange requirement for me.
Are you sure that you have a problem with blank padded characters?
select 1, '|'||rtrim('sxxx ')||'|' from dual
UNION
select 2, '|'||'sxxx '||'|' from dual;
Row#     1     '|'||RTRIM('SXXX')||'|'
1     1     |sxxx|
2     2     |sxxx |

How to view a stored procedure from sql plus

Can anyone please tell what is the command for viewing the content of the stored procedure from sql plus ?

Hi,
I use this simple script to retrieve.......

Hi,
do you need LTRIM/RTRIM? This is namely your problem. By using a function around your column Oracle reserves the maximum lenght for the column. So what do you get without those functions? Furthermore you are concatenating all the columns. This is also a function. For getting '|' in between columns you can also set a seperator by using
set colsep '|'Herald ten Dam

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.
begin
call_SWNPost('http://www.sendwordnow.com/usps/getNotificationResults',vMessageText, vReplyMessage, v_status_code, v_status_phrase, '');

when others then
raise eJavaException;
end;
vTextReply := dbms_lob.substr( vReplyMessage, 32000, 1 );
if (vDebug) then
update PEMS_PROD_2.SWN_POST_LOG set response = 'notif_id == '|| v_notification_id || 'status code == '|| v_status_code|| ' '||vTextReply where log_pk = vLogPK;
commit;
end if;
IF v_status_code = 200 then
v_has_error := 'N';
ELSE
v_has_error := 'Y';
END IF;
-- we handle all exceptions below in case something goes wrong here.
-- this area can die silently.
vTextReply := replace(vTextReply,'<getNotificationResultsResponse xmlns="http://www.sendwordnow.com/usps">', '<getNotificationResultsResponse xmlns:xyz="http://www.sendwordnow.com/usps">');
begin
insert into swn_recip_response_t(notification_id) values (v_notification_id);
exception
when others then
if (vDebug) then
err_num := SQLCODE;
err_msg := SUBSTR(SQLERRM, 1, 100);

Invoking SQL*Plus from tool or contextmenu bug

If connection was created using the Basic-Tab everything is fine.
If used TNS-Tab and network alias sql*plus menu point is greyed out .
If used TNS-Tab and connect identifier or Advanced-Tab sql*plus is invoke with the wrong
connect string.
Example:
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=host1.abc.com)(PORT=51001))(ADDRESS=(PROTOCOL=tcp)(HOST=host2.abc.com)(PORT=51001)))(CONNECT_DATA=(SERVICE_NAME=DEV)))
Result: sqlplus starts but with wrong connect string
SQL*Plus: Release 10.2.0.1.0 - Production on Tue Mar 14 10:24:17 2006
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Enter password:
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified

It does seem to be fairly arbitrary whether SQL*Plus is available or not. I have many connection definitions covering 9i to 11g and SQL*Plus is not available for a random selection of them. They are all defined using the Basic connection tab and I can't see any differences between the one which work and the one which don't.
It also doesn't make much sense to disable it if the focus is in the sql worksheet and not on a node of the connection navigator.
Why should it be necessary to define sqlplus as an external tool to get round arbitrary limitations when it should be supported directly.
I hope these problems are being addressed for the next release.

Apex 4.0 - Can see view data in SQL*Plus but no data in Object Browser

Hi There,
I have just started using Apex 4.o and migrated some apps. I have an issue with a report, but see the same issue with Object browser, which is easier to describe.
I have a view:
create or replace view V_PLJ_USERDEF_CODES (
         CODE_SET_ID,
         CODE_SET_CODE,
         CODE_SET_DESC,
         CODE_ID,
         CODE_SYS_CODE,
         CODE_VALUE,
         CODE_DESC,
         DISPLAY_SEQ,
         DISPLAY_FLAG,
         LANGUAGE_CODE) as
select CS.CODE_SET_ID,
         CS.CODE_SET_CODE,
         CS.CODE_SET_DESC,
         C.CODE_ID,
         C.CODE_SYS_CODE,
         C.CODE_VALUE,
         C.CODE_DESC,
         C.DISPLAY_SEQ,
         C.DISPLAY_FLAG,
         C.LANGUAGE_CODE
    from PLJ_CODES C,
         PLJ_CODE_SETS CS
   where C.CODE_SET_ID         = CS.CODE_SET_ID
     and CS.CODE_SET_TYPE_CODE = SYS_CONTEXT('PLJUMPSTART','C_USERDEF_CODE_SET');This returns data in SQL*Plus, but no data in Object Browser OR report region based on this view.
Workspace parses in the same schema as tested in SQL*Plus.
If, in report, I swap out view, and use underlying table - no problem.
Any ideas -
thanks
P

Hi all,
Thanks for getting back so promptly.
It just seems weird to me, as tables are just fine, but not views.
In the underlying schema:
SQL> sho user
USER is "ICSREPORTING"
SQL> select count(*) from plj_codes;
COUNT(*)
       107
SQL> select count(*) from v_plj_userdef_codes;
COUNT(*)
        29And in the APEX schema
SQL> sho user
USER is "APEX_040000"
SQL> select count(*) from icsreporting.plj_codes;
select count(*) from icsreporting.plj_codes
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> select count(*) from icsreporting.v_plj_userdef_codes;
select count(*) from icsreporting.v_plj_userdef_codes
ERROR at line 1:
ORA-00942: table or view does not exist
SQL>However, in SQL browser, I can see the data in PLJ_CODES but in V_PLJ_USERDEF_CODES, just the message "This view has no data". Indeed, it is like this for all views.
I even explicitly granted access to APEX_040000 but no good.
In fact, I would like to know more about how Apex gets access to do DML against the underlying parsing schema(s).
This is a little frustrating though. It worked just fine in lots of apps in version 2.1 to 3.2
Am I missing something
paul
p.s I knew there would be a question about the context, but I had already checked that. :)

How to use blank space replace NULL on discoverer viewer

Hi,
There is a report that has a varchar field should show text values, and if NULL, I need it show blank space, and does in disco desktop, but on viewer, the same worksheet shows NULL.
Even I changed in the Tools - Options - Format menu(desktop), it still show NULL on viewer.
why?
please help! thanks!
sammy

Hi Sammy,
Unfortunately ‘some’ of the settings set in Desktop do not carry over to Viewer. These options need to be defined for Viewer itself.
A temporary way to set the Viewer settings is to click on ‘Options’ when logged in Viewer itself. You’ll have to open a responsibility or report before this option becomes available to select. Within here you’ll be able to change the way NULL values are seen. However this method only makes the change for the User you logged in with.
To make the change for all users, it’s best to edit the PREF.TXT file on the Discoverer Server. Please view the documentation below for more information on how to configure Viewer. For windows platform click here : http://download-uk.oracle.com/docs/html/A90287_01/toc.htm,
For Unix platform click here : http://download-uk.oracle.com/docs/html/A90288_01/toc.htm. Once you’ve run the applypreference script, these settings will be forced down to all users of Discoverer.
Hopefully this will help ;-)

Blank spaces in code view

Hello,
Whenever I copy and paste text from another website -- sometimes from my own website after it goes live -- onto Dreamweaver, the text looks just fine in Design view. Fonts and paragraphs are preserved, as they're supposed to according to my preferences.
However, when I look at the code view, there are always several -- sometimes a whole lot of -- blank spaces separating words; blank spaces that were not in the original text (even in code view) and that can't be detected in Dreamweaver's design view.
It looks ok online just like it looks ok in Dreamweaver's design view, but I'm just a little concerned that those blank spaces may confuse search engine crawlers.
For instance. In design view and online, one sees:
"Great Holiday"
but in the code view/source page you'll see
"Great Holiday"
That's what the crawlers and spiders will see as well. And they may think that "Great Holiday" and "Great Holiday" are two different sets of keywords when they should be the same.
How can I ensure that only *one* blank space is allowed in Dreamweaver's code view, whenever I copy and paste text from webpages? Is there a way that I can preserve the texts' format and fonts while ensuring *one* blank space in code view?
Any suggestions would be much appreciated.

No, actually this is what happens:
If one of us copies text from our blog online (www.altfg.com/blog/) we see the following in Dreamweaver's design view:
Right behind Clash of the Titans, DreamWorks Animation’s How to Train Your Dragon, featuring the voices of Jay Baruchel, Gerard Butler, and
America Ferrera, earned $3.8 million (+9.2%) domestically on Thursday,
but in code view there are blank spaces between words. Blank spaces that shouldn't be there:
Right behind <a href=
"http://www.altfg.com/blog/movies-431/clash-of-the-titans-box-office-predictions/"
>Clash of the Titans</a>, DreamWorks Animation’s How to Train Your Dragon, featuring the voices of Jay Baruchel, <a href=
"http://www.altfg.com/blog/photos/bradley-cooper-gerard-butler-andrew-r-jones-810/"
>Gerard Butler</a>, and America Ferrera, earned $3.8 million (+9.2%) domestically on Thursday, 
Notice the blank spaces separating "featuring the voices" or "Gerard Butler." Those shouldn't be there. Maybe it makes no difference. On the browsers, it all looks fine. But is there a way to ensure that Dreamweaver doesn't allow more than one blank space between words in code view?
Also, *no one* has responded to my query about automatic hyperlinks for images. Any ideas?
That has been such a drag.

Error creating view with CASE -- WHEN statement in SQL*Plus

I am using Oracle 8i 8.1.7
I have an Oracle view which uses CASE...WHEN statements.
The view compiles fine in DBA studio.
Using TOAD I saved the view as an *.sql file.
However, when I try to create the view in SQL*Plus I get the following error:
SP2-0734: unknown command beginning "CASE WHEN ..." - rest of line ignored.
According to the documentation CASE -- WHEN has been implemented since since Oracle 8i rel. 2 (8.1.6)

Well I'm using 8.1.6.3 and CASE and DECODE both work for me:

Before header pl/sql process creates blank space at top of page

Hi,
I'm finding that w/v 1.6.1 I get a blank space at the top of my page that appears to be somewhat proportional to the amount of code and/or # processes on that page that are before header. moving to after header and before regions also shows this behavior.
There are no blank line outputs happening in the pl/sql processes, so I've got no idea why htmldb is putting blank space there.
Anyone seen anything like this? Oracle 9.2.0.7, winxp pro
Thanks
matt

Hi,
I've had the same problem. I'm assuming that you have a region in the "After Header" position?
If so, you could add the following in the region's Region Header:
<div style="display:none">
and put this in the Region Footer:
</div>
The region is defined in a table, which by definition is a block object. Block objects always begin on a new line and end with a new line - the above will put the region into a div and then hide the div.

VIEW XML IN SQL*PLUS

how can we view xml on sql*plus?
when xmltype is viewed on sql*prompt it shows incomplete xml.
example:
SQL> select xmlelement("ROOT",xmlforest(1 as A, 2 as B, 3 as C)) from dual;
XMLELEMENT("ROOT",XMLFOREST(1ASA,2ASB,3ASC))
<ROOT>
<A>1</A>
2
<C>3</C>
</ROOT>
but i generate an xml from table so it becomes quite huge. say a forest is populated with 6-8 tags. it shows broken output.
SQL> /
ID LIST
<DEPT>
<EMPLOYEE>
<ID>2109</ID>
<ID>3108</ID>
<ID>4107</ID>
<ID>5106</ID>
<ID
i have tried increasing bufferwidth and bufferlength tp max value (1000 and 2000 respectively) eventhen it displays the output as shown above.
how can i view my xml?

use this sql plus command:
set long 2000000
You can increase\decrease the value as required.

Need to find out View definition by SQL PLUS

Hi,
I have a view VW_XXX, I want to know by which table this view has created. But need to use only SQL PLUS not any tool.
Please let me know how cani see the full definitio of the view by SQL PLUS.
Regs,

Yes, it will work for both 9i and 10g. Just run the commands, and you will get the output.
These are not "Dangerous Commands!!!"

Edited by: Girish Sharma on Dec 26, 2011 5:19 PM
To solve these issues Oracle9i has introduced the DBMS_METADATA package which can be used to retrieve object definitions as DDL or XML. There are a number of ways to use the API, but I suspect the majority of people will only ever use the following functions.

Viewing tables in sql plus

hai friends.,
i created a java database pgm using jdbc:odbc connectivity, that creates a table in the database and i inserted some records in that table. how can i view those table and records in the sql plus. what commands are used to view those table
regards.,
sekar

Hi sekar,
Interesting, you're able to do a 'CREATE TABLE bla...' but are not familiar with 'SELECT'? I would suggest to read some basic stuff about SQL statements. What will you do when the next task is: "Hey, I need a pgm to change these values in the table!"?

Viewing Binary data in SQL*PLUS

hi all,

the error seems that the binary data cannot be view thru SQL PLUS.
do anybody have idea to solve this issue.
thanks in advance

Probably you are trying to view BLOB data. Try this to view the data:
SQL> CREATE TABLE t (a BLOB)
2 /
Table created.
SQL> INSERT INTO t
2 VALUES (UTL_RAW.cast_to_raw ('Hello World'))
3 /
1 row created.
SQL> SELECT UTL_RAW.cast_to_varchar2 (a) a
2 FROM t
3 /

Encoding for blank spaces in url in a sql statement in report

1. What function or process do I use to encode for blank spaces in a url link in a report?
I need to link from a report to a 2nd report and pass 5 variables. I believe that I need to do that by embedding my own url in the sql for the report, since the standard report sets up for only 3 variables to be passed.
One of my variables PARTNER_FIRM has spaces in it, so how do I encode for that in the query. Currently, I have the following (... simplified).
select partner_firm,
count(distinct event) distinct_events,
'<a href="f?p=18509:4:&SESSION.::NO:4:P4_PARTNER_FIRM,P4_QUARTER,P4_CATEGORY,P4_PRODUCT_CATEGORY,P4_EVENT:' ||
partner_firm ||
'%2C&P3_QUARTER.%2C&P3_CATEGORY.%2C&P3_PRODUCT_CATEGORY.%2C&P3_EVENT.">' ||
count(distinct lower(attendee_email)) || '</a>' distinct_attendees
from all_events ...
but partner_firm has spaces which are returned. I think there is some way that I can encode for that?
Thanks,
Stephen

Sure there is:
select apex_util.url_encode('http://ww.oracle.com/') from dual
