преобразование VARCHAR в INT сбой на динамический запрос SQL Server 2008

/ 29 апреля 2019

Я пытаюсь создать динамическое предложение WHERE, если параметр не -1.это означает, что это не NULL (я добавил -1 в мое веб-приложение, чтобы сделать некоторые проверки JS, поэтому по умолчанию используется параметр -1, что означает, что в фильтре ничего не выбрано на тот случай, если вам интересно, почему -1и не NULL находится на моей проверке)

Проблемы здесь 2:

  1. Если я запускаю exec(@sql) sql возвращает error converting nvarchar value 'insert dynamic query here'. to data type int Я незнаете, что я делаю не так?

  2. Не знаю, как сделать условие для AND с.Я попытался выполнить запрос, но все еще добавлял условие ADD, даже когда получил параметр -1, что означает, что он не должен появляться в запросе, потому что это NULL.

Я уже пытался добавить некоторые цитаты и прочее в часть + в запросе, но, похоже, ничего не работает

Я ожидаю сделать динамический запрос, но я оченьзапутался в том, что нужно сделать, чтобы это заработало.
