Don't hesitate to send me patches for testing in Oracle. There are more problems when running on Oracle, but they can be eliminated:
1. Famous Oracle error 'identifier is too long' - usually happens in models like db.define_table('headers',...) db.define_table('details', SQLFIELD('header_id', 'header') ) Web2py builds constraint for key field and it is named something like 'detais_header_id__constraint' - and this often exceeds 31 chars limit allowed by Oracle for all identifiers. I suggest to make suffix shorter, e.g. '_c' or just '_' otherwise I have to globally rename readable identifiers to something like 'a_b' in all of my code. 2. Maybe my design fault, but anyway: open source databases usually truncate strings if you write 'longtextmanychars' to VARCHAR(8). Grown up guys like Oracle don't allow this and give error. I tried to write a fix-up function like def truncate_string(sql_field, string): if sql_field.type=='string': return string[:sql_field.length] else: return string but this completely breaks for international texts. Adding unicode (string, 'utf-8') and so on similar to your code in SQLTABLE truncate does not help - Oracle VARCHAR2(255) does not let my strings in. Thank you!
