[Dbix-class] Using 'like' query with data containing wildcard characters requiring ESCAPE?

[Kenneth Ölwing]

Hi,

I happen to have text data in my table that has the '_' (underscore) 
character, and I wanted to do a like search.

So to find all rows with '_' I did:

     my @rows = $rs->search( { data => { like => '%_%' } } );

and running with DBIC_TRACE=1, I see:

     SELECT me.data FROM test me WHERE ( data LIKE ? ): '%_%'

I didn't get the result I was expecting. And duh, it dawned on me that 
'_' is itself a wildcard char...

After realising that, I researched and found out that I could write 
something like this (a direct query):

     SELECT * FROM test WHERE (data LIKE '%\_%' ESCAPE '\');

Being a beginner with DBIx::Class, I may not have found the right place 
to look, but so far no luck...can I achieve this effect with the Perl 
code, and if so how? I'm using SQLite for the moment and Perl 5.16 and 
latest DBIx::Class.

TIA, any help appreciated.
