Обсуждение: Scan SQL
Hi I need to make a parser in a sql to get tables and fields to verify the privileges. Do anybody know software, function or anything that can help me? I found software to create a compiler and generate the source in delphi, but I need a sql specification (BNF, EBNF) and I do not know where to find it. Thanks Sandro

I probably can, but I'm not quite sure what you're asking for. Could you explain at greater length, maybe with some examples? -Josh Berkus

You could look at how PostgreSQL does its parsing.

Josh The good, will be, see the sample below, return field list and table list of the sql and to analyse it to give permission or not to open the table in delphi. select a, b, c, d from z, x Sandro ----- Original Message ----- From: "Josh Berkus" <josh@agliodbs.com> To: "Sandro Joel Eller" <sandro@tecsoft.com.br>; <pgsql-sql@postgresql.org> Sent: Tuesday, July 23, 2002 3:40 PM Subject: Re: [SQL] Scan SQL > Sandro, > > > I need to make a parser in a sql to get tables and fields to verify > > the > > privileges.
