Android SQLite Query - Getting latest 10 records

Question

I have a database saved in my Android application and want to retrieve the last 10 messages inserted into the DB.

When I use:

Select * from tblmessag         


        

Answer 1

If your table contains a column with primary key autoincrement (some "row_id" for example) then you just need single select with DESC order by this column

Raw request looks like

select * from table_name order by row_id DESC limit 10

Android implementation is

private Cursor queryLastEvents() {
    return getDatabase().query("table_name", null, null, null, null, null, "row_id DESC", "10");
}
