Hi all,


here iam updating a table which is having 70 columns and more than 10 thousand records, even col names are also big....

whenever displaying the table it is displaying in zig zag format and it is not readable.So iam not able to identify either data is updated or not.

Iam using oracle 10g and running select * from tablename command..

Is there any command to display table with too many columns in a formatted way please let me know..

Regards,

Ramakrishna M

For a table which has many columns, perhaps installing and using a GUI tool is the easiest solution. Oracle offers a free tool called SQL Developer. Visit Oracle Technology Network pages to download this product.

Otherwise, you might write a query which would select only desired column(s) instead of all of them. Or, there's a possibility to select table contents "vertically" instead of "horizontally"; there are several solutions to it. I *think* I have a script somewhere so, if you decide to use such an approach, I'll look for it.

1/ Don't use IM Speak
2/ Don't use URGENT nothing is urgent in forum
3/ Post in the correct, you will have a faster answer -> SQL Client Tools
4/ Read SQL*Plus manual you will know how to format your columns and lines

Regards
Michel

Have a look at the section on Formatting Reports. Since you are trying to format a report, I would suggest that you look there to learn the report formatting techniques (I know, I know it's a bit subtle, I mean, who would have thought to look in the index for a word like format, but there you have it)

OK, here it is - a script written by David L. Hunt.

As some Forum members can not download and open attachments (although this is a pure TXT file), I'll post the whole script.

Following is my "VSelect.sql" (Vertical SELECT) script. (It does use PL/SQL's UTL_FILE package to
write a temporary script file [TempVWriter.sql] to your default SQL*Plus directory. So, ensure that
your Oracle instance's "UTL_FILE_DIR" parameter is either set to "*" or at least to your SQL*Plus 
default directory. The script will prompt for 1) the name of your table (or view), 2) "WHERE" clause
(if needed), and 3) "ORDER BY" clause (if needed).

Following, then, are 1) the contents of the script (which you should save to your own script in order 
to execute), 2) a sample VSelect.sql invocation, 3) and resulting output.

Seems that dh_file package is needed. Google and you will easily find it.
