突然有一个需求,客户需要把某一些数据导出成Excel,之前没有做过这方面的需求,Goolg了一下,可以用BCP来完成,但是最后发现导出的Excel有换行了,所以最终把数据的内容的换行符,回车符,双引号替换掉,下面是是代码(只适用于偶尔的数据导出)
select * into test2 from CUS_QDiathesis update test2 set QD_TARGET=REPLACE(convert(nvarchar(4000),QD_TARGET),CHAR(13) , ''), QD_SELFCOMMENT=REPLACE(convert(nvarchar(4000),QD_SELFCOMMENT),CHAR(13) , ''), QD_SUPERVISORCOMMENT=REPLACE(convert(nvarchar(4000),QD_SUPERVISORCOMMENT),CHAR(13) , ''), QD_IMPROVETARGET=REPLACE(convert(nvarchar(4000),QD_IMPROVETARGET),CHAR(13) , ''), QD_IMPROVEPLAN=REPLACE(convert(nvarchar(4000),QD_IMPROVEPLAN),CHAR(13) , ''), QD_ESTIMATEDATE=REPLACE(convert(nvarchar(4000),QD_ESTIMATEDATE),CHAR(13) , ''), QD_FINISHINFO=REPLACE(convert(nvarchar(4000),QD_FINISHINFO),CHAR(13) , ''), QD_PERFORMANCE_REQUIREMENT=REPLACE(convert(nvarchar(4000),QD_PERFORMANCE_REQUIREMENT),CHAR(13) , ''), QD_DETAIL_ACTIONPLAN=REPLACE(convert(nvarchar(4000),QD_DETAIL_ACTIONPLAN),CHAR(13) , '') go update test2 set QD_TARGET=REPLACE(convert(nvarchar(4000),QD_TARGET),CHAR(10) , ''), QD_SELFCOMMENT=REPLACE(convert(nvarchar(4000),QD_SELFCOMMENT),CHAR(10) , ''), QD_SUPERVISORCOMMENT=REPLACE(convert(nvarchar(4000),QD_SUPERVISORCOMMENT),CHAR(10) , ''), QD_IMPROVETARGET=REPLACE(convert(nvarchar(4000),QD_IMPROVETARGET),CHAR(10) , ''), QD_IMPROVEPLAN=REPLACE(convert(nvarchar(4000),QD_IMPROVEPLAN),CHAR(10) , ''), QD_ESTIMATEDATE=REPLACE(convert(nvarchar(4000),QD_ESTIMATEDATE),CHAR(10) , ''), QD_FINISHINFO=REPLACE(convert(nvarchar(4000),QD_FINISHINFO),CHAR(10) , ''), QD_PERFORMANCE_REQUIREMENT=REPLACE(convert(nvarchar(4000),QD_PERFORMANCE_REQUIREMENT),CHAR(10) , ''), QD_DETAIL_ACTIONPLAN=REPLACE(convert(nvarchar(4000),QD_DETAIL_ACTIONPLAN),CHAR(10) , '') go update test2 set QD_TARGET=REPLACE(convert(nvarchar(4000),QD_TARGET),'"' , ''), QD_SELFCOMMENT=REPLACE(convert(nvarchar(4000),QD_SELFCOMMENT),'"' , ''), QD_SUPERVISORCOMMENT=REPLACE(convert(nvarchar(4000),QD_SUPERVISORCOMMENT),'"' , ''), QD_IMPROVETARGET=REPLACE(convert(nvarchar(4000),QD_IMPROVETARGET),'"' , ''), QD_IMPROVEPLAN=REPLACE(convert(nvarchar(4000),QD_IMPROVEPLAN),'"' , ''), QD_ESTIMATEDATE=REPLACE(convert(nvarchar(4000),QD_ESTIMATEDATE),'"' , ''), QD_FINISHINFO=REPLACE(convert(nvarchar(4000),QD_FINISHINFO),'"' , ''), QD_PERFORMANCE_REQUIREMENT=REPLACE(convert(nvarchar(4000),QD_PERFORMANCE_REQUIREMENT),'"' , ''), QD_DETAIL_ACTIONPLAN=REPLACE(convert(nvarchar(4000),QD_DETAIL_ACTIONPLAN),'"' , '') go
下面是创建一个视图用BCP导出的代码
CREATE view [dbo].[ReportView] as select c.*, a.* from test2 a, EVA_QuarterEvaluate b, SEC_User c where a.QUARTEREVALUATE_ID=b.QUARTEREVALUATE_ID and b.USER_ID=c.USER_ID GO EXEC 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(); }
