Сохраненная процедура занимает больше времени для выполнения

Question

Выполняю хранимую процедуру im MYSQL. Это будет генерировать 6000 записей и вставить эти 6000 записей в таблицу. Для этого эта хранимая процедура занимает более 45 минут. Размер хранимой процедуры составляет 45 КБ. Системная память составляет 0,98 ГБ. Оказывает ли системная память влияние на производительность хранимой процедуры?

Answer 1

1. Вы должны проверить, какое утверждение точно в хранимой процедуре требуется время, добавив несколько точек отладки (например: Вы можете вставить метку после каждого выбора в какой-нибудь временную таблицу).
2. Вам нужно проверить, что у вас есть правильные индексы на таблице для выбора запросов.
