Wild Cards

select * from testdata where key like '%substring%';

It uses regular expression form, not file glob form.
Try percent signs before and after the substring
you want to match.

It's % and you have to use the LIKE operator.

SELECT * FROM thistable WHERE name LIKE '%marley';

Alternatively use regular expressions as with grep:

SELECT * FROM thistable WHERE name ~* 'scrooge$'

~ is regular expression match
~* is case-insensitive regular expression match
