Yes, the sql_yacc.y is used to generate the sql parser. The
parser is used more to "run" the sql rather than to break it into its
tokens. Using the lex files would be closer to your stated goals. The
file lex.h in the same directory as sql_yacc.y contains all the tokens

I am looking for code that will take an SQL command and break it into it's parts. I
have found some attempts, but none that use the
code from an actual SQL engine, and big surprise, they don't work 100%.
I have a few goals:
1) developer tool: cut/paste the SQL command and get a pretty format di

I'm taking a database implementation course, and my professor has flipped
his lid this semester and assigned one of the labs to be an SQL parser and
optimizer (using equivalence rules, etc.). Given an SQL statement and a
database schema (with some statistical metadata on the contents), I

Besides the performance issue there is another problem with SQL:
The ISAM-API has a different meaning of a cursor than in SQL. I can set this
