How to display table data more clearly in oracle sqlplus

I usually start with something like:

set lines 256set trimout onset tab off

Have a look at help set if you have the help information installed. And then select name,address rather than select * if you really only want those two columns.

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE----------- ---------- -------------- ---------          1 HSBC       Nugegoda Road      43434          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10column address format a20column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10column address format a20column telephone format 999999999select name, address, telephonefrom mytable;

You can set the line size as per the width of the window and set wrap off using the following command.

set linesize 160;set wrap off;

I have used 160 as per my preference you can set it to somewhere between 100 - 200 and setting wrap will not your data and it will display the data properly.
