表格 每页 单独 是 这样查 select * from 表 where id in(一组编号)
如果 页长 是 10 ， id 里面的 数据 如 ： 1001,1002,1003...,1010
为什么这样写 减少连接数据库次数。
再拿 分段数据 搜索你要展示的数据
可以考虑用DataTable对象select方法，搜索具体某个产品编号对应的产品信息 DataRow[] arrDr = dt.Select("Productid=" + id);
好处：减少数据库压力。
/// <summary>
/// 通过pid得到订单区域,数据源为预先查好的DataTable
/// </summary>
/// <param name="id">产品id</param>
/// <returns></returns>
public string[] GetOrderById(DataTable dt, int id)
{
string[] result = new string[4];
for (int i = 0; i < result.Length; i++)
{
result[i] = "0";
}
if (dt != null && dt.Rows.Count > 0)
{
DataRow[] arrDr = dt.Select("ProductID=" + id);
if (arrDr != null && arrDr.Length > 0)
{
result[0] = Convert.ToString(arrDr[0]["PrepayMent"]);
result[1] = Convert.ToString(arrDr[0]["Profit"]);
result[2] = Convert.ToString(arrDr[0]["Person"]);
result[3] = Convert.ToString(arrDr[0]["Child"]);
}
}
return result;
}
/// <summary>
/// 根据产品id集合查询 意向和online订单数和成功单 （总数）
/// </summary>
/// <returns></returns>
public DataTable GetNewOrderPurposeCountByIds(string pids, LineEntity model)
{
StringBuilder sb = new StringBuilder();
if (model.StartTime != "" && model.EndTime != "")
sb.AppendFormat(" and joindate between '{0}' and '{1}'", model.StartTime,
Convert.ToDateTime(model.EndTime).AddHours(23).AddMinutes(59).AddSeconds(59).ToString());
string sql = string.Format(@"
SELECT PRODUCTID,COUNT(CASE WHEN IsSupplierReturn = 0 THEN 1 END) ORDERCOUNT,
count(CASE WHEN IsSupplierReturn =0 AND firstname='客户' THEN 1 END ) as onlineCount,
COUNT(CASE WHEN IsSupplierReturn =0 AND ENABLE IN (7,8) THEN 1 END) AS SUCCEEDCOUNT
FROM view0010(nolock)
WHERE ProductID in({0}) {1}
GROUP BY PRODUCT ID
", pids, sb.ToString());
DataTable table = SQLHelper.SqlHelper.ExecuteDataTable(sqlcon, CommandType.Text, sql);
return table;
}
好处：这种处理方法 适合 数据量比较大 ，关联的表比较多，在性能方面有很大的提升。
我的方式： 主表里面 只有3个字段可用 select a,b,c from 表 .
其它的 e,d,f,....列用 组装 分段数据来实现
