Android Question
Logging SQL queries in android
I am using the
querySo far the best I could do was to have a look at the cursor's member mQuery using a breakpoint. I'd love to output the queries automatically though. This member is of course not public and does not have a getter.
Just for the record, here is an implementation of the accepted answer.
/**
* Implement the cursor factory in order to log the queries before returning
* the cursor
*
* @author Vincent @ MarvinLabs
*/
public class SQLiteCursorFactory implements CursorFactory {
private boolean debugQueries = false;
public SQLiteCursorFactory() {
this.debugQueries = false;
}
public SQLiteCursorFactory(boolean debugQueries) {
this.debugQueries = debugQueries;
}
@Override
public Cursor newCursor(SQLiteDatabase db, SQLiteCursorDriver masterQuery,
String editTable, SQLiteQuery query) {
if (debugQueries) {
Log.d("SQL", query.toString());
}
return new SQLiteCursor(db, masterQuery, editTable, query);
}
}

You can apply your own SQLiteDatabase.CursorFactory to the database. (See the openDatabase parameters.) This will allow you to create your own subclass of Cursor, which keeps the query in an easily accessible field.
edit: In fact, you may not even have to subclass Cursor. Just have your factory's newCursor() method return a standard SQLiteCursor, but log the query before doing so.
