I'm working on updating a Sequel adapter (sequel-vertica) for my own
nefarious purposes (actually, I'm adding support for COPY FROM STDIN), and
I am running across a problem trying to get all the existing tests to pass.
It seems that when Sequel sees a dataset filter like: @ds.filter(name: /bc/)
that it wants to turn this into WHERE "name" ~ /bc/ but Vertica doesn't
support ~; instead it wants to use WHERE "name" REGEXP_LIKE('bc'). When I
traced this, it seemed to be a result of looking up a set of filter types
in Sequel::SQL::StringExpression::LIKE_MAP. I'm not clear on how I could
coerce the Vertica adapter to use REGEXP_LIKE instead of ~ in this context.
What should I try?
