in reply to Automatically altering tables from different schema's

Years ago, I made a program that compared database objects (not just tables), and reported the differences (column names, column types, order in which columns appeared, constraints, presence of triggers and indices, etc). But that was for Sybase, and there all the information is available in SQL tables, making it rather easy.

I could also compare the SQL object creation code with what was present in the database. I did not attempt to parse the SQL using a Perl program - I simply loaded the object in an another database, and compared the newly created object with the object already there.

Unfortunally, I don't have easy access to the code anymore.
