Обсуждение: Case sensitivity issue

If I am doing a command such as

select * from Apples where color like '%red%';

how do I make it case insensitive?

Thanks.

mike

Use: ILIKE

SELECT * FROM apples WHERE lower(color) LIKE '%red%';

Make sure that what ever 'red' might be is always lower case (you can pass
it through lower() too, of course)..

use "ILIKE" instead of "LIKE"
or use a regular expression match: ~* 'red'

I was trying to solve a similar problem where I wanted an exact match to work
in PostgreSQL and MySQL and ended up with:

        lower(Field) = lower('string')

Is there another way that works on both?
