我有一个网格视图。在此之下，我使用了一些参数，如@LHNoofOverdueEMI 和@LHDisbDate。我想通过大于或等于@LHNoofOverdueEMI 的值并等于来自@LHDisbDate 的任何月份或年份的特定日期值的值进行查询。以下都是详细信息：
页面.aspx
<asp:SqlDataSource ID="DSGVRecList" runat="server"
ConnectionString="<%$ ConnectionStrings:OptimaWebCustomerQueryCon %>"
SelectCommand="select LHID, LHAcNo, LhAcName, LHIntRate, LHDisbDate
LHDrawingPower, LHtotalDisbAmt, LHEMI, LHNoofOverdueEMI, LHUploadDate
from dbo.TblLoanHistory where
(YEAR(LHUploadDate) = YEAR(GETDATE())) AND (MONTH(LHUploadDate) = MONTH(GETDATE()))
AND LHNoofOverdueEMI ???
AND LHDisbDate ??? "
onselecting="DSGVRecList_Selecting">
<SelectParameters>
<asp:ControlParameter ControlID="txtNoofOverDue" Name="LHNoofOverdueEMI" PropertyName="Text" />
<asp:ControlParameter ControlID="txtEMIDate" Name="LHDisbDate" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource>
C＃
protected void DSGVRecList_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
if (txtEMIDate.Text.Length == 0) e.Command.Parameters["@LHDisbDate"].Value = "%";
else e.Command.Parameters["@LHDisbDate"].Value = txtEMIDate.Text;
if (txtNoofOverDue.Text.Length == 0) e.Command.Parameters["@LHNoofOverdueEMI"].Value = "%";
else e.Command.Parameters["@LHNoofOverdueEMI"].Value = txtNoofOverDue.Text;
}
