func is just a catchall, whatever attribute you call off of it gets sent to __getattr__ and becomes a function call. its designed to allow any random database-specific call or custom stored procedure.
however, it does have some extra tricks going on, in that it will "de-parenthesize" certain ANSI calls that are known to not want parenthesis, like "CURRENT_TIMESTAMP". the docs are here: http://www.sqlalchemy.org/docs/sqlconstruction.myt#sql_whereclause_functions which you probably found, and it does need a good amount more explanation. a. that you can call whatever name you want, and it becomes a function b. that it knows about certain ANSI calls and c. that you can create "selectables" out of functions now, which is useful for calling stored procedures that return result sets. its not in the generated docs because its just an instance variable, that points to an instance of _FunctionGenerator which is "private". --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
