And I will be pleased that data is gone! I really did not expect anything but this.
If I need such tolerant behavior, then this shall be a feature of my special app, not a feature of the database... If the developer does not know how to write sql, then is time to learn. If the problem is the dynamic generated Sql, then I must write more test cases to cover these new scenarios. But IMHO, database must fail always (syntax or not...).
Regards,
Edson
