a sequence should instead override Dialect.getCreateSequenceStrings(java.lang.String)

limit clauses when they support limits. Thus, when building the
select command we do not actually need to know the limit or the offest
since we will just be using placeholders.
Here we do still pass along whether or not an offset was specified
so that dialects not supporting offsets can generate proper exceptions.
In general, dialects will override one or the other of this method and
