'LIKE ('%this%' OR '%that%') and something=else' not working

I have a select query where I am trying to search strings for multiple patterns

LIKE ('%this%' or '%that%' ) and something=else

Returns zero results

However

LIKE '%this%' and something=else

returns results and

LIKE '%that%' and something=else

returns result

Is it possible to get all my results into one query? If a string matches both, how will it handle that?

It would be nice if you could, but you can't use that syntax in SQL.

Try this:

(column1 LIKE '%this%' OR column1 LIKE '%that%') AND something = else

Note the use of brackets! You need them around the OR expression.
Without brackets, it will be parsed as A OR (B AND C),which won't give you the results you expect.

Instead of using LIKE, use REGEXP. For example:

SELECT * WHERE value REGEXP 'THIS|THAT'

mysql> SELECT 'pi' REGEXP 'pi|apa';                     -> 1
mysql> SELECT 'axe' REGEXP 'pi|apa';                    -> 0
mysql> SELECT 'apa' REGEXP 'pi|apa';                    -> 1
mysql> SELECT 'apa' REGEXP '^(pi|apa)$';                -> 1
mysql> SELECT 'pi' REGEXP '^(pi|apa)$';                 -> 1
mysql> SELECT 'pix' REGEXP '^(pi|apa)$';                -> 0

Refer: http://dev.mysql.com/doc/refman/5.1/en/regexp.html

Try something like:

WHERE (column LIKE '%this%' OR column LIKE '%that%') AND something = else

Break out the LIKE clauses into 2 separate statements, i.e.:

(fieldname1 LIKE '%this%' or fieldname1 LIKE '%that%' ) and something=else
