Re: DB2 for i "Backus?Naur Form" specification

David,

Just to point out...BNF won't tell you if indexe, mqts, triggers or
constraints are used in a statement. The DBMS references those behind the
scenes.

Well technically, I think you could have a statement reference a MQT
directly...but that would appear as simply another table/view reference.

What are you trying to accomplish?

As the primary owner of the IBM i SQL BNF, I would be interested in
hearing what you are looking for in the statement text. If it is
something that might be generally useful (like a list of table
names), I might be able to create a service that uses the IBM i
parser to return these pieces of information.

Sue:

I'm primarily interested in parsing SQL source to identify objects used in
the statement.

For example: Tables & views used by views, indexes, & mqts. Also,
constraint relationships, triggers, etc.

I have the ability to process a BNF into a parser program, but an API that
gives me the information would be even better.
