求教：有关ASP.net中SqlDataSource与GridView的问题!

int   ElapseDay   =   3;
string   TableTitle   =   "t_ ";
string[]   sTmpTable;
sTmpTable   =   new   string[4];

SqlDataSource1.Delete(); //   "DELETE   FROM   tmp_Query "

for   (int   i   =   0   ;   i   <   ElapseDay   ;   i++)
{
sTmpTable[i]   =   TableTitle   +   Convert.ToString(Convert.ToInt32( "20070410 ")   +   i);
SqlDataSource1.SelectCommand   =   "INSERT   INTO   tmp_Query   SELECT   *   FROM   "   +   sTmpTable[i] ";
}

SqlDataSource1.SelectCommand   =   SqlDataSource1.SelectCommand;
//   已经在控件上绑定
//GridView1.DataSource   =   SqlDataSource1.SelectCommand;
GridView1.DataBind();

谢谢

你上面的用的是SqlDataSource1.SelectCommand
后面又是SqlDataSource1.InsertCommand

是不是这里有错误呀

看不懂你的代码，有种自虐倾向。

SqlDataSource1.SelectCommand = "INSERT INTO tmp_Query SELECT * FROM " + sTmpTable[i] ";

这里是insert，怎么是 selectcommand呢?
