The QueryGenerator class

[joebordes]

QueryGenerator class is a very powerful query abstraction capable of generating very complex SQL for any module in the system.
At a very high level it is:
- instantiate against a module
- indicate the fields you want
- indicate the conditons
- ask for the SQL

Look at the unit test for some examples:
