Hi,=0ADoes anybody know if there is a way to parse and view the AST for an =
SQL Query in Derby? I looked at the sqlparser.jj in the source code, but co=
uldn't find a way to start it and parse a query without hacking into all th=
e code.=0A=0ASome thing like this one: http://www.experlog.com/gibello/zql/=
 ?=0A=0AI am especially interested in extending the SQL grammar a little bi=
t by adding a few keywords and re-writing some queries issued by the user. =
So,  some kind of a Visitor-pattern would be nice.=0A=0AThanks,=0AAshwin (w=
ww.JavaForU.com).=0A=0A=0A=0A=0A=0A=0A=0A=0A=0A=0A=0A=0A
