Hi all.
I am new to ASP and working in Expression Web. The followingquery
displays the information I need in the gridview for a single record.
SELECT "OE_HDR"."ORD_NO", "OE_HDR"."CUST_NAM", "OE_HDR"."SLS_MAN_NO",
"OE_HDR"."SLS_MAN_INITIALS", "OE_HDR"."ORD_DAT", "OE_HDR"."SHIP_DAT"
FROM "OE_HDR" WHERE ("OE_HDR"."ORD_NO"='174310')
I also have DropDownList1 working properly. For the WHERE portion of
the query I would like to pass a variable that references thevalue of
DropDownList1
SELECT "OE_HDR"."ORD_NO", "OE_HDR"."CUST_NAM", "OE_HDR"."SLS_MAN_NO",
"OE_HDR"."SLS_MAN_INITIALS", "OE_HDR"."ORD_DAT", "OE_HDR"."SHIP_DAT"
FROM "OE_HDR" WHERE ("OE_HDR"."ORD_NO"= @"DropDownList1")
I have been searching for the propoer syntax and have been unable to
get it functioning properly.
Thank you!
I think
<asp:SqlDataSource
...
WHERE OE_HDR.ORD_NO = @DropDownList1
">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="DropDownList1"
PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>

Thanks for the reply.
Here is the code that works and displays one record based on the
definitive ...WHERE OE_HDR.ORD_NO= '140173'">
<asp:SqlDataSource runat="server" ID="SqlDataSource2"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT OE_HDR.ORD_NO, OE_HDR.CUST_NAM,
OE_HDR.SLS_MAN_NO, OE_HDR.SLS_MAN_INITIALS, OE_HDR.ORD_DAT,
OE_HDR.SHIP_DAT FROM OE_HDR WHERE OE_HDR.ORD_NO= '140173'">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList2"
Name="DropDownList2"
PropertyName="SelectedValue"
Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
When I change the code to use the variable:
<asp:SqlDataSource runat="server" ID="SqlDataSource2"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT OE_HDR.ORD_NO, OE_HDR.CUST_NAM,
OE_HDR.SLS_MAN_NO, OE_HDR.SLS_MAN_INITIALS, OE_HDR.ORD_DAT,
OE_HDR.SHIP_DAT FROM OE_HDR WHERE OE_HDR.ORD_NO= @DropDownList2">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList2"
Name="DropDownList2"
PropertyName="SelectedValue"
Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
I get this error in my page:

Any Ideas?
Thanks again for you help.- Hide quoted text -

wait... I made a misspelling, don't you see it?
<asp:ControlParameter
ControlID="DropDownList2"
Name="DropDownList2"
Name should be a name of the db-field, e.g. ORD_NO- Hide quoted text -
- Show quoted text -
I changed to name to ORD_NO and also changed the query to reflect that
change:
<asp:SqlDataSource runat="server" ID="SqlDataSource2"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT OE_HDR.ORD_NO, OE_HDR.CUST_NAM,
OE_HDR.SLS_MAN_NO, OE_HDR.SLS_MAN_INITIALS, OE_HDR.ORD_DAT,
OE_HDR.SHIP_DAT FROM OE_HDR WHERE OE_HDR.ORD_NO= @ORD_NO">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList2" Name="ORD_NO"
PropertyName="SelectedValue"
Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
Same Error now except the last error now references ORD_NO

I am wondering if this is not more of a PervasiveSQL problem with the
syntax of the variable rather than an ASP qestion...- Hide quoted text -
