User filter for LIKE and wildcards

[kuopaz]

In SQL (SQL Server) I would use: Col LIKE '[A-L]%'

to find all Col values starting with letter A through to L.

How do you do this in Looker, I’ve tried putting [A-L]% in matches (advanced).

There’s no built-in functionality that would let you do that at the moment. 

Greg_sanders had a workaround using parameter and templated filters here:
