從ExecuteSqlCommand

Question

這裏執行Sp_SetAppRole是我的代碼：

  SqlParameter rolename = new SqlParameter("rolename", SqlDbType.VarChar); 
      rolename.Direction = ParameterDirection.Input; 
      rolename.Value = "role";     

      SqlParameter password = new SqlParameter("password", SqlDbType.VarChar); 
      password.Direction = ParameterDirection.Input; 
      password.Value = "123@123"; 

      SqlParameter fCreateCookie = new SqlParameter("fCreateCookie", SqlDbType.Bit); 
      fCreateCookie.Direction = ParameterDirection.Input; 
      fCreateCookie.Size = 100; 
      fCreateCookie.Value = true;     

      SqlParameter cookie = new SqlParameter("cookie", SqlDbType.VarBinary); 
      cookie.Direction = ParameterDirection.Output; 
      cookie.Size = 8000; 

      _context.Database.ExecuteSqlCommand(TransactionalBehavior.DoNotEnsureTransaction, "EXEC sp_setapprole @rolename,@password,@fCreateCookie, @cookie OUT;", rolename, password, fCreateCookie, cookie); 

而且我正在一個錯誤：

正式參數「@fCreateCookie」未聲明作爲輸出參數，但實際參數傳入請求的輸出。

有人能告訴我我做錯了什麼嗎？

Answer 1

你缺少一個參數

ALTER procedure [sys].[sp_setapprole] 
     @rolename sysname,  -- name app role 
     @password sysname,  -- password for app role 
-->  @encrypt varchar(10) = 'none',  -- Encryption style ('none' | 'odbc') 
     @fCreateCookie bit = 0, 
     @cookie varbinary(8000) = 0xFFFFFFFF OUTPUT 
    as 

您需要在您的通話executesqlcommand
