Sorry for my completely ignorance, but what can be the use of parsing SQL?
Suppose from the point of view of a database driver that receives queries,
or from a ORM point of view....does it make sense for something?
Thanks

Hi all,
i did implement an SQL parser using Petit Parser.
I toke the grammar
specification from SQLite http://www.sqlite.org/lang.html . The grammar
implemented is not complete, for now i did implement "just" the create table
statement, it means that you should be able to parse at least a script for
create the database.
The code is in squeaksource
http://www.squeaksource.com/@09zbthA-fDDfyUNQ/_OIex3aA .
To download it you can evaluate this:
Gofer new
squeaksource: 'PetitSQLParser';
package: 'ConfigurationOfPetitSQLParser';
load.
(Smalltalk at: #ConfigurationOfPetitSQLParser) perform: #loadDefault
in the repository there are several packages: the core contains the parser
for the grammar.
In the package parser there is a parser that instantiate some draft
objects representing relational elements.
In the next future i will start to implement also other statements.
If you start to use it and you have some problem please let me know.
Cheers,
Fabrizio
