如何使用事务SQL在try catch块中删除临时表

Question

你好，我在try catch块中有以下查询事务，如果失败，我会在catch块上回滚事务。问题是我正在创建一个临时表，但我不知道如何通过事务处理它。那么在这种情况下如何安全地摆脱临时表呢？我试图将其添加到catch块上，但是我不确定这是否是一个好习惯

我正在从带有Entity Framework Core的Asp .NET Core应用程序调用SP

  await _context.Database
        .ExecuteSqlCommandAsync("EXEC @Status = GetDataForNewListaAbastecimento @UAP, @ColaboradorId", @params);

尝试添加此内容：

如果OBJECT_ID（'tempdb ..＃Results'）不是空表＃结果

（替换您的临时表#Result的名称）
