MVC 3中的Sql错误

我一直得到一个错误说:

c附近语法错误"(sql error

)

但是我看不出为什么。我在Studio Management中运行了这个程序，没有出现任何问题。下面是我的方法:

public string GetSecurityDetails(int contactId)
{
    ContactId = contactId;
    using (DataAccess da = new DataAccess())
    {
        da.Execute("SELECT c.ContactId,c.SecurityQuestionAnswer,q.Name" +
                   "FROM profile.SecurityQuestion q" +
                   "INNER JOIN profile.Contact c ON q.SecurityQuestionID = c.SecurityQuestionFK" +
                   "WHERE c.ContactID = @Contact",new SqlParameter("@Contact",contactId));
        while(da.Read())
        {
            SecurityAnswer = da.GetValue<string>("securityQuestionAnswer");
            SecurityQuestion = da.GetValue<string>("Name");
            break;
        }
    }
}

我正在使用ASP。. NET MVC 3 in Visual Studio 2010

da.Execute(
           "SELECT c.ContactId,c.SecurityQuestionAnswer,q.Name FROM profile.SecurityQuestion q " +
           "INNER JOIN profile.Contact c ON q.SecurityQuestionID = c.SecurityQuestionFK " +
           "WHERE c.ContactID = @Contact",new SqlParameter("@Contact",contactId)
           );

da.Execute(
           @"SELECT c.ContactId,c.SecurityQuestionAnswer,q.Name FROM profile.SecurityQuestion q
           INNER JOIN profile.Contact c ON q.SecurityQuestionID = c.SecurityQuestionFK
           WHERE c.ContactID = @Contact",new SqlParameter("@Contact",contactId)
           );
