SQL語句 分頁查詢數據

分頁查詢詳情：

分頁查詢SQL語句

select top (@limit) * from (select row_number() over(order by FId desc) as rownumber,* from T_Products ) temp_row where rownumber>@offset 

@limit：條數

@offset ：最小條數

order by FId desc：數據根據FId倒序

T_Products：表格名稱

分頁查詢通常配合計算sql計算總條數語句（select COUNT(1) from T_Products）使用

 

實例：

 /// <summary>
        /// 前台分頁查詢產品數據
        /// </summary>
        /// <param name="limit">條數</param>
        /// <param name="offset">最小條數</param>
        /// <param name="total">返回總條數</param>
        /// <returns></returns>
        public DataTable GetQueryList(int limit, int offset, string Type, out int total){
       //使用sql語句分頁查詢數據
                string sql = "select top (@limit) * from (select row_number() over(order by FId desc) as rownumber,* from T_Products ) temp_row where rownumber>@offset ";
                //計算數據總條數
                string totalsql = "select COUNT(1) from T_Products ";
                total = Convert.ToInt32(SqlHelper.ExecuteScalar(SqlHelper.connStr, totalsql));
                //使用鍵值對 對sql語句里的占位建進行替換
                SqlParameter[] para = new SqlParameter[]
                {
                new SqlParameter("@limit",SqlDbType.Int),
                new SqlParameter("@offset",SqlDbType.Int),
                
                };
                para[0].Value = limit;
                para[1].Value = offset;
                //返回一個Table
                return SqlHelper.ExecuteDataTable(SqlHelper.connStr, sql, para);
}
