When I run a query like:
SELECT * FROM CAR;
the results appear but each row wraps to several lines.
How can I stop this wrapping so
Really hard to tell quite what the question actually is; but if you're seeing each row of data wrapped onto multiple lines in SQL*Plus, you need to do set lines 180
or similar; the number you use would ideally be the width of your terminal. The default is 80. You can go wider than the terminal, and it will still wrap, but you may find it easier to read still.
The documentation for all the set
commands is here.
