In the example in the SqlDelight documentation, the HockeyPlayerModel
generated by SqlDelight from a HockeyPlayer.sq
file is implemented in an abstract class public abstract class HockeyPlayer implements HockeyPlayerModel
In this class, the string SELECT_ALL_INFO
is passed in as the query to db.rawQuery(SELECT_ALL_INFO, new String[0])
. The string SELECT_ALL_INFO
was generated by the select_all_info
statement inside HockeyPlayer.sq
. However, in my situation, my statements are not generating strings. Why is this?
My statement
names_for_groups:
SELECT DISTINCT name, exercise_set_group FROM exercise_set JOIN exercises
USING (exercise_id) WHERE workout_FK = ? ORDER BY exercise_set_group ASC ;
My implementation of the ExerciseSetModel
being generated by SqlDelight
@AutoValue
public abstract class DbExerciseSet implements ExerciseSetModel, DbItem {
public static final Factory<DbExerciseSet> FACTORY = new Factory<>(AutoValue_DbExerciseSet::new);
public static final RowMapper<DbExerciseSet> MAPPER = FACTORY.select_allMapper();
public static final RowMapper<NamesForGroups> NAMES_FOR_GROUPS_MAPPER =
FACTORY.names_for_groupsMapper(AutoValue_DbExerciseSet_NamesForGroups::new);
public List<NamesForGroups> namesForGroups(SQLiteDatabase db) {
List<NamesForGroups> namesForGroupsList= new ArrayList<>();
Cursor cursor = db.rawQuery(NAMES_FOR_GROUPS, new String[0]);
while (cursor.moveToNext() && NAMES_FOR_GROUPS_MAPPER.map(cursor) != null) {
//NamesForGroups namesForGroups = NAMES_FOR_GROUPS_MAPPER.map(cursor);
namesForGroupsList.add(NAMES_FOR_GROUPS_MAPPER.map(cursor));
}
return namesForGroupsList;
}
@AutoValue
public abstract static class NamesForGroups implements Names_for_groupsModel {}
@AutoValue
public abstract static class Exercises implements ExerciseModel {}
}
To be clear, the variable reference NAMES_FOR_GROUPS is not found in the line db.rawQuery(NAMES_FOR_GROUPS, new String[0])
The documentation needs to be updated, I'll do that. We no longer generate Strings in SQLDelight 0.6.+ instead there is a method on the factory which returns a SQLDelightStatement
that is used to query:
public List<NamesForGroups> namesForGroups(SQLiteDatabase db) {
List<NamesForGroups> namesForGroupsList= new ArrayList<>();
SQLDelightStatement query = FACTORY.name_for_groups();
Cursor cursor = db.rawQuery(query.statement, query.args);
while (cursor.moveToNext() && NAMES_FOR_GROUPS_MAPPER.map(cursor) != null) {
//NamesForGroups namesForGroups = NAMES_FOR_GROUPS_MAPPER.map(cursor);
namesForGroupsList.add(NAMES_FOR_GROUPS_MAPPER.map(cursor));
}
return namesForGroupsList;
}
