OracleException (0x80131938): ORA-01036，变量名或数值无效。
请高手帮忙看一下，不胜感激。
本程序的功能是在执行grv1的时候，实现grv1的数据distinct，然后以一个id对应多个在grv2中ID相同的记录的形式显示.
id | name

以下是程序代码：
protected void Page_Load(object sender, EventArgs e)
{
.......
String sqlcmd = " SELECT DISTINCT id FROM emp";
using (OracleConnection cn = COMUtility.GetConnection())
{
using (OracleDataAdapter da = new OracleDataAdapter(sqlcmd, cn))
{
DataSet ds = new DataSet();
da.Fill(ds, "emp");
DataTable dt = new DataTable();
dt = ds.Tables["emp"];
grv1.DataSource = ds.Tables["emp"];
grv1.DataBind();
}
}
.......
}
protected void grv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
System.Data.DataRowView drv = (DataRowView)e.Row.DataItem;
String id drv.Row.ItemArray[0].ToString();
SqlDataSource sds = e.Row.FindControl("SqlDataSource1") as SqlDataSource;
sds.SelectParameters["id"].DefaultValue = id;
}
}
aspx代码：
<asp:GridView ID="grv1" runat="server" AutoGenerateColumns="False" DataKeyNames="id" AllowPaging="True" AllowSorting="True" PageSize="10" OnRowDataBound="grv1_RowDataBound" >
<Columns>
<asp:BoundField DataField="id" HeaderText="id" />
<asp:TemplateField HeaderText="" />
<ItemTemplate>
<asp:GridView ID="grv2" DataSourceID = "SqlDataSource1" runat="server" AutoGenerateColumns="False" DataKeyNames="name" >
<Columns>
<asp:BoundField DataField="name" HeaderText="name" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT * FROM emp WHERE [id] = @id">
<SelectParameters>
<asp:Parameter Name="id" type="String" />
</SelectParameters>
</asp:SqlDataSource>
