SQL query to match one of multiple strings

Question

I have following data in table:

+----------------------+----------------------------------------------------------+--------------+
| subscriber_fields_id | n         


        

Answer 1

You can use this:

select * from subscriberfields
where  name like any(array['%Khairpur%','%Islamabad%','%Karachi%']);

Answer 2

Use OR in WHERE clause, like,

select * from subscriberfields where name like '%Khairpur%' OR name like '%Islamabad%' OR name like '%Karachi%';

Hope it works.

Answer 3

Try using SIMILAR TO like below:

SELECT * FROM subscriberfields 
WHERE name SIMILAR TO '%(Khairpur|Islamabad|Karachi)%';

Also you should read up on database normalization. Your design could and should definitely be improved.

Answer 4

For a proper solution, either normalize your database design or, barring that, consider full text search.

For a quick solution to the problem at hand, use a regular expression match (~) or three simple LIKE expressions:

SELECT *
FROM   subscriberfields 
WHERE  name ~ '(Khairpur|Islamabad|Karachi)';

Or:

...
WHERE (name LIKE '%Khairpur%'
    OR name LIKE '%Islamabad%'
    OR name LIKE '%Karachi%')

Or use ~* or ILIKE for case-insensitive matching.

Since another answer suggested it: never use SIMILAR TO:

• Using SIMILAR TO for a regex?
• Pattern matching with LIKE, SIMILAR TO or regular expressions in PostgreSQL
