Hi!
I think translate is overkill here.
Use:
select col from tab where col like 'v\_lan' escape '\';
vs
> Select col1 from table > where translate(col1,'_','#') like 'v#lan%' > /
Not only is the escape method cleaner, it's much more efficient. Unless you have an index on translate(col1,'_','#') (unlikely), that query will always result in a sequential scan. Ugh.
