/**********************Excel导到Txt****************************************/
想用
select * into opendatasource(...) from opendatasource(...)
实现将一个Excel文件内容导入到一个文本文件

假设Excel中有两列，第一列为姓名，第二列为很行帐号(16位)
且银行帐号导出到文本文件后分两部分，前8位和后8位分开。

邹健：
如果要用你上面的语句插入的话,文本文件必须存在,而且有一行:姓名,银行账号1,银行账号2
然后就可以用下面的语句进行插入
注意文件名和目录根据你的实际情况进行修改.

insert into
opendatasource('MICROSOFT.JET.OLEDB.4.0'
,'Text;HDR=Yes;DATABASE=C:/'
)...[aa#txt]
--,aa#txt)
--*/
select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8)
from
opendatasource('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:/a.xls'
--,Sheet1$)
)...[Sheet1$]

如果你想直接插入并生成文本文件,就要用bcp

declare @sql varchar(8000),@tbname varchar(50)

--首先将excel表内容导入到一个全局临时表
select @tbname='[##temp'+cast(newid() as varchar(40))+']'
,@sql='select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8)
into '+@tbname+' from
opendatasource(''MICROSOFT.JET.OLEDB.4.0''
,''Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:/a.xls''
)...[Sheet1$]'
exec(@sql)

--然后用bcp从全局临时表导出到文本文件
set @sql='bcp "'+@tbname+'" out "c:/aa.txt" /S"(local)" /P"" /c'
exec master..xp_cmdshell @sql

--删除临时表
exec('drop table '+@tbname)

/********************导整个数据库*********************************************/

delete from openquery(mailser,'select * from yulin')

select * from openquery(mailser,'select * from yulin')

update openquery(mailser,'select * from yulin where id=15')set disorder=555,catago=888

insert into openquery(mailser,'select disorder,catago from yulin')values(333,777)

补充：

对于用bcp导出,是没有字段名的.

用openrowset导出,需要事先建好表.

用openrowset导入,除ACCESS及EXCEL外,均不支持非本机数据导入

 

 

前几天，一直在网上搜索资料，想实现这个功能，都没找到我想要的结果，最后只要自己想办法实现了。
      大体思路是：将EXCEL的数据提出放在数据集中，在过循环将主表数据插入，在通过循环将从表插入：
代码如下：

private void button1_Click(object sender, System.EventArgs e)
{
//选择文件
  ofdSelectExcel.Filter = "Excel Files(*.xls)|*.xls";
  ofdSelectExcel.RestoreDirectory = true;
  if( ofdSelectExcel.ShowDialog() == DialogResult.OK )
  {
 if ( ofdSelectExcel.FileName.Trim().Length == 0)
 {
   MessageBox.Show(this,"Please select a excel file first!");
   return;
 }
 else
 {
  ImportExcelToSqlServer(ofdSelectExcel.FileName.Trim());
 }
       
 }
}

 }

 string oleDBConnString = String.Empty;
 oleDBConnString = "Provider=Microsoft.Jet.OLEDB.4.0;";
 oleDBConnString += "Data Source=";
 oleDBConnString += fileName;
 oleDBConnString += ";Extended Properties=Excel 8.0;";

 
 OleDbConnection oleDBConn = null;
 OleDbDataAdapter oleAdMaster = null;
 DataTable m_tableName=new DataTable();;
 DataSet ds=new DataSet();
 try
 {
    oleDBConn = new OleDbConnection(oleDBConnString);
    oleDBConn.Open();
    m_tableName=oleDBConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,null);
  
    if (m_tableName != null && m_tableName.Rows.Count > 0)
    {

  m_tableName.TableName =m_tableName.Rows[0]["TABLE_NAME"].ToString();

    }
  string sqlMaster;
  sqlMaster=" SELECT *  FROM ["+m_tableName+"]";
  oleAdMaster=new OleDbDataAdapter(sqlMaster,oleDBConn);
  oleAdMaster.Fill(ds,"m_tableName");
   
  MailRebateManager manger=new MailRebateManager();
  bool isSucess=manger.AddExceLGmailRebate(ds.Tables["m_tableName"],ApplicationVariable.HomeCompanyID);
  if(isSucess)
  {
   MessageBox.Show("Manipulate Succs!");
  }
  else
  {
    MessageBox.Show("Manipulate Failed");
