When selecting data from Oracle tables, the default line width can often be shorter than the lines of
data you wish to view. This causes the text to wrap around, making it very hard to read. To avoid
this problem you can change the Oracle default settings to increase the width of the lines, using the
set command.
Eg. At the SQL*Plus command line, type:
set linesize 200 - this will change the line width to 200 characters.
You could try a few different line size settings unitl you find the size that suits you
