_sql: SQL code executed upon creation of the object (only if _auto is True). It means this code gets executed after the table is created.


_auto: Determines whether a corresponding PostgreSQL table must be generated automatically from the object. Setting _auto to False can be useful in case of OpenERP objects generated from PostgreSQL views. See the “Reporting From PostgreSQL Views” section for more details.

For example in sale.order class if you are defining _auto=False, sale_order table will not be created in PostgreSQL database.

_auto=False option mostly used to generated PostgreSQL views. You can see example of _auto here and here

_sql: SQL code to create the table/view for this object (if _auto is False) – can be replaced by SQL execution in the init() method. (Reference: Technical Memento )
