Is there a way to create a select statement that will select a record if the exact term is found in a field that contains the text to describe something?
If I create a select statement using WHERE description LIKE ‘art’ I get every record that has words like depart, start and so on.
If I create a select statement using WHERE description = ‘art’ I get no results even though the word art is in some records description field.
Use a regular expression instead of LIKE, and the left- and right-word-boundary expressions (see section 9.7 of the Postgres manual):
db=> select 'the quick brown fox' ~ '[[:<:]]brown[[:>:]]'; ?column? ---------- t
=> select 'the quick brown fox' ~ '[[:<:]]own[[:>:]]'; ?column? ---------- f
