SQL数据 导出Excel

下面是创建一个视图用BCP导出的代码

CREATE view [dbo].[ReportView]asselect c.*, a.* from test2 a,   EVA_QuarterEvaluate b,  SEC_User  c    where a.QUARTEREVALUATE_ID=b.QUARTEREVALUATE_ID and b.USER_ID=c.USER_IDGOEXEC master..xp_cmdshell 'BCP "SELECT * FROM MLK_PDP.dbo.ReportView" queryout c:\currency5.xlt -c -U"sa" -P"sa"'go

注意：可能上面执行需要启用xp_cmdshell,下面是启用命令

EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;关闭一样.只是将上面的后面的那个"1"改成"0"就可以了. EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 0;RECONFIGURE;

最后发现，在正式环境，我的帐户没有执行exec 的权限（那时郁闷呀），所以最终还是用Asp.Net代码来处理，下面是用asp.net 导出成Excel的代码

        protected void btnExport_Click(object sender, EventArgs e)        {                        SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["MLK_PDPConnectionString"].ConnectionString);            string strsql = "select * from ReportView";            SqlCommand cmd = new SqlCommand(strsql, conn);            conn.Open();            SqlDataAdapter da = new SqlDataAdapter(cmd);            DataTable dt = new DataTable();            da.Fill(dt);            CreateExcel(dt, "dia.xlt");                    }        private void CreateExcel(DataTable dt, string fileName)        {            HttpResponse resp;            resp = Page.Response;            resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");            resp.AppendHeader("Content-Disposition", "attachment;filename=" + fileName);            string colHeaders = "", ls_item = "";            ////定义表对象与行对象，同时用DataSet对其值进行初始化            //DataTable dt = ds.Tables[0];            DataRow[] myRow = dt.Select();//可以类似dt.Select("id>10")之形式达到数据筛选目的            int i = 0;            int cl = dt.Columns.Count;            //取得数据表各列标题，各标题之间以t分割，最后一个列标题后加回车符            for (i = 0; i < cl; i++)            {                if (i == (cl - 1))//最后一列，加n                {                    colHeaders += dt.Columns[i].Caption.ToString() + "\n";                }                else                {                    colHeaders += dt.Columns[i].Caption.ToString() + "\t";                }            }            resp.Write(colHeaders);            //向HTTP输出流中写入取得的数据信息            //逐行处理数据             foreach (DataRow row in myRow)            {                //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据                   for (i = 0; i < cl; i++)                {                    if (i == (cl - 1))//最后一列，加n                    {                        ls_item += row[i].ToString() + "\n";                    }                    else                    {                        ls_item += row[i].ToString() + "\t";                    }                }                resp.Write(ls_item);                ls_item = "";            }            resp.End();        }
