Я хотел бы оптимизировать соединение между следующими таблицами, пожалуйста, сообщите.
Дополнительные вопросы:
- Лучше всего использовать все индексы между всеми таблицами
- Лучше всего использовать синтаксис FROM A соединение B на A.ID = B.ID (быстрее)?
Какое условие будет обработано в первую очередь (оптимизатор так же заботится о наилучшем присоединении)?
Скажите, пожалуйста, несколько советов, какдля оптимизации.
Количество строк таблицы:
- inv.mtl_material_transactions = 17.466.581
- inv.mtl_transaction_lot_numbers = 13.680.350
- gme.gme_material_details = 5.302.282
- gme.gme_batch_header = 790.828
- inv.mtl_system_items_b = 516.148
- GMD.fm_matl_dtl = 280.056 *
