Я попытался выполнить этот код, и он работал нормально без хранимой процедуры, и с ним он сделал ошибку.
ошибка: Сообщение 102, Уровень 15, Состояние1, процедура UV_MTBF, строка 251 Неверный синтаксис рядом с «Событием _».
Имеет ли хранимая процедура ограничение по длине?Может ли кто-нибудь помочь мне с моим кодом?
***** edit ****** Моя проблема с '+ QUOTENAME (@ category, N' '' ') + N' я хочу добавитьцелое число от переменной, которую я получил в хранимой процедуре.как я могу это сделать?
введите код здесь:
