Howto: LIKE statement in views arguments?

Hi.
When using arguments in views of drupal I can implement some kind of filters.
E.g.: Get only nodes with specific title.
The generated SQL query uses a "=" (equal) operator. So the user has to enter the exact title he is looking for. I want to change the "=" to the LIKE-operator. But I have no clue how to do so.
Any ideas?

Thanks in advance.

LIKE '%Operator%' instead of = Operator

The '%' stands for any number of characters, 0+
You can have the % at the start, at the end, both or not at all (which would make it the same as =)

Sorry this might be clearer:

LIKE '%text%' instead of = 'text'

The '%' stands for any number of characters, zero or more
You can have the % at the start, at the end, both or not at all (which would make it the same as =)

You might want to take into account case sensitivity as well by using UPPER() or LOWER() on both sides of the operator.

e.g. UPPER('%text%')

I know the SQL-Syntax for the LIKE-operator. My problem is the interface to setup the view. Or to be more specific the arguments of the view. There is no option to change the "=" to LIKE.

So the problem is not solved :(

If you google hook_query_alter you will find a way to make alterations to the views query. http://www.nicklewis.org/hook-views-query-alter-how-programatically-alter-views-queries

You'll want the devel module installed so that you can use dpm.
