Ok, I am going to write support for this, but I need some help with
determining if a character is valid for a dollar-quote tag. I am
currently looking at the original patch implementing dollar-quoting in
the backend parser, see here:
http://developer.postgresql.org/cvsweb.cgi/pgsql/src/backend/parser/scan.l.diff?r1=1.114;r2=1.115
scan.l defines:
dolq_start [A-Za-z\200-\377_]
dolq_cont [A-Za-z\200-\377_0-9]
Some questions here:
- What are the \200-\377 characters?
- Any ideas how to efficiently check this in Java?
There is Character.isLetter() etc., but this includes all Unicode
letters, not only letters valid as identifiers in the backend.
Otherwise I can still use something like
public static boolean isDollarQuoteStartChar(char c) {
return (c >= 'A' && c <= 'Z') || ...
}
I am currently working on dollar-quote support in
v3.QueryExecutorImpl.parseQuery(..), but I also want to add it to
V2Query. Where should I put such a static method like
isDollarQuoteStartChar? org.postgresql.core.Utils?
Best Regards
