ORMLite with CursorAdapter in Android
Your comments indicate that you've already answered you problem. You can certainly create a column named "_id" using ORMLite:
@DatabaseField(generatedId = true)
private int _id;
or
@DatabaseField(generatedId = true, columnName = "_id")
private int id;
If you are working with Cursor
s then you may want to take a look at the last()
and moveAbsolute(...)
methods on the DatabaseResults
class. Also, the AndroidDatabaseResults
(which you can cast to) also has a getRawCursor()
method which returns the underlying Cursor
object and has additional getCount()
and getPosition()
methods.
Here are some more information about ORMLite and Cursor
s:
Android Cursor with ORMLite to use in CursorAdapter
You can get access to the Cursor
using something like the following:
// build your query
QueryBuilder<Foo, String> qb = fooDao.queryBuilder();
qb.where()...;
// when you are done, prepare your query and build an iterator
CloseableIterator<Foo> iterator = dao.iterator(qb.prepare());
try {
// get the raw results which can be cast under Android
AndroidDatabaseResults results =
(AndroidDatabaseResults)iterator.getRawResults();
Cursor cursor = results.getRawCursor();
...
} finally {
iterator.closeQuietly();
}
It turns out I did need a raw SQL query with ORMLite after all as I needed to do a Left Join, (i.e. not as a result of having to rename the id column in a query, that is not necessary as per Gray's answer above)
The way I did it is below:
public class DatabaseHelper extends OrmLiteSqliteOpenHelper{
public void myRawQueryMethod() {
SQLiteDatabase database = this.getReadableDatabase();
String SqlQuery = "Write raw SQL query here";
Cursor cursor = database.rawQuery(SqlQuery, null);
}
}
Thanks for advice
