How to display table data more clearly in oracle sqlplus

Question

I want to be able to display the resulting data from a select in a pretty way, not all columns under others.

Here is the way sqlplus displays my table data:

Answer 1

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 a10
column address format a20
column 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 a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;
