android – greendao delete from db and session

Posted by: admin June 15, 2020 Leave a comment


I’m using greendao for a android project and wanted to know how to properly delete and object from the db and from the session cache. Currently I do the following to delete from the db:

ChatDao chatDao = daoSession.getChatDao();

However as the method name and documentation state this may leave stale objects in the session cache, how can I remove the objects from there too?

How to&Answers:

In order to clear cached objects in your DaoSession use this call:


It will clear all objects in your session identity scope.


As Anatoliy described, you can use DaoSession.clear(). However, it will clear all all objects from the session. If you want to avoid that, you have to execute a regular query and delete the result entities (for example with deleteInTx).
