Я написал запрос для сбора некоторых данных, которые будут отображаться в окне автообновления и вискера в Excel. Я хотел бы использовать сведение для создания итоговых строк для каждого типа train_line (PF и MJ) для включения в диаграмму Excel.
Могу ли я сделать это с помощью Rollup?
Я пытался свести голову с Rollup, но я не ухожу далеко. Я пытался просто обернуть это вокруг случайных вещей в моей группе, но это не помогло, что я хотел.
Вот как выглядят первые несколько столбцов результатов.
DUMP_YEAR DUMP_WEEK LINE MINE PRODUCT CODE
2009 30 MJ MJ C MJ-C
2009 30 PF BR F BR-F
2009 30 PF BR L BR-L
2009 30 PF HD F HD-F
2009 30 PF HD L HD-L
2009 30 PF MA F MA-F
2009 30 PF MA L MA-L
2009 30 PF NM F NM-F
2009 30 PF NM L NM-L
2009 30 PF PA F PA-F
2009 30 PF PA L PA-L
2009 30 PF TP F TP-F
2009 30 PF TP L TP-L
2009 30 PF WA F WA-F
2009 30 PF WA L WA-L
2009 30 PF YA F YA-F
А вот и мой SQL-запрос.
