第 1 行: 'PublishArticle' 附近有语法错误。请各位帮小弟看看，谢谢各位了
如下错误提示：，这个是分页取数据，但是出现错误，我实在看不出，请大家帮帮我，谢谢了
下面是我部分代码：

web层代码：

int RecordCount = 0;
        int PageSize = 10;//每页显示的条数
        int PageIndex = 1;//当前页数        

 public DataTable GetArticle(int userId)
        {
            Article articleBll = new Article();
            string strUrl = string.Format("BlogDefault.aspx?userId={0}&", userId);
            DataTable dt = articleBll.StructureArticleListDefault(userId, PageSize, PageIndex, out RecordCount);
    return dt;
         }


BLL代码：        

/// <summary>
        /// 构造首页博文列表
        /// </summary>
        /// <param name="userId"></param>
        /// <param name="pageSize"></param>
        /// <param name="pageIndex"></param>
        /// <param name="recordCount"></param>
        /// <returns></returns>
        public DataTable StructureArticleListDefault(int userId,int pageSize,int pageIndex,out int recordCount)
        {
            string strWhere = "PublishArticle.IsShow = 1 and PublishArticle.ArticleFrom < 2 and ";
            strWhere += "PublishArticle.UserId = "+userId;
                       
            DataTable dt = dal.GetDefaultArticleData(pageSize, pageIndex, out recordCount,strWhere);           
            return dt;
        }

DAL代码：

/// <summary>

        /// <param name="PageIndex"></param>

        /// <param name="strWhere"></param> 
        public DataTable GetDefaultArticleData(int PageSize, int PageIndex, out int RecordCount,string strWhere)
        {
            string tabName = "Tab_Article as Article inner join Tab_PublishArticle as PublishArticle on Article.ArticleId = PublishArticle.ArticleId";
            string fieldName = "PublishArticle.RecordId,Article.PublisherId, PublishArticle.ArticleId,";

            string fieldSort = "PublishArticle.CollectionTime";

            SqlParameter[] parameters = new SqlParameter[] { 
                new SqlParameter("@tblName", SqlDbType.NVarChar, 300),
                new SqlParameter("@fldName", SqlDbType.NVarChar, 800), 
                new SqlParameter("@pageSize", SqlDbType.Int),
