Hi, all
How to retrieve data from two tables via the ContentProvider way?
I.E. the database of Calendar application, include many tables
including Events and Deleted, and some others.
I want to retrive records in Events table, whose _sync_id field is
also in Deleted table.
Usually, we write a SQL sentence like:
select (all fields in Events)
from Events as e, Deleted as d
where e._sync_id = d._sync_id
or select *
from Events as e
where e._sync_id in select _sync_id from Deleted
etc.
But, how can I accomplish it in the ContentProvider way? I saw
ContentProvider.query take a Uri as the first parameter, but pity that
I don't know how to build one that could fulfil my purpose.
Hope you could help me a hand, thank you:-)
