Re: select exact term

I am struggling with the syntax. In php I create my where clause as shown, using ~* for case insensitive:
$search = "art";
$strSQL2 = "WHERE (title ~* [[:<:]]'$search'[[:>:]] OR description ~* [[:<:]]'$search'[[:>:]]) ";

When executed zero records are returned even though the ILIKE statement shown below returns records that do have the word art.

$search = "art";
$strSQL2 = "WHERE (title ILIKE '%$search%' OR description ILIKE '%$search%') ";

Thanks for the insight.

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
