Have you tried :

<cfquery datasource="#Application.DataSource#" username="xx" password="cccc" name="test4">
          UPDATE orderhistory
          SET orderhistory.OrderID = #GetNewOrderID.MaxOrderID#
          WHERE orderhistory.OrderID = 0
          AND NOT orderhistory.itemoid = 0
     </cfquery>

well before i did that i just tested this line

#GetNewOrderID.MaxOrderID#

i switched it with 9999

and it worked.

You should be able to reference it that way.  Are you sure that you are getting results from the first query?

Try this :

<cfquery datasource="#Application.DataSource#" username="xxx" password="xxxx" NAME ="GetNewOrderID">
     SELECT MAX(OrderID) as MaxOrderID
     FROM itemlist
     </cfquery>

     <cfif GetNewOrderID.RecordCount EQ 0><cfabort showerror="No Records Pulled"></cfif>

     <cfquery datasource="#Application.DataSource#" username="xx" password="cccc" name="test4">
          UPDATE orderhistory
          SET orderhistory.OrderID = #GetNewOrderID.MaxOrderID#
          WHERE orderhistory.OrderID = 0
          AND orderhistory.itemoid <> 0
     </cfquery>

Also try removing the space between name= and the "GetNewOrderID">

try this , i think the max returned is null..
     <cfquery datasource="#Application.DataSource#" username="xxx" password="xxxx" NAME = "GetNewOrderID">
     SELECT isNull(MAX(OrderID),1) as MaxOrderID
     FROM itemlist
     </cfquery>
     
     <cfquery datasource="#Application.DataSource#" username="xx" password="cccc" name="test4">
          UPDATE orderhistory
          SET orderhistory.OrderID = #GetNewOrderID.MaxOrderID#
          WHERE orderhistory.OrderID = 0
          AND orderhistory.itemoid <> 0
     </cfquery>

if isNull doesn't work that way in mysql then do this

<cfquery datasource="#Application.DataSource#" username="xxx" password="xxxx" NAME = "GetNewOrderID">
     SELECT MAX(OrderID) as nMaxOrderID
     FROM itemlist
     </cfquery>

<cfif GetNewOrderID.Recordcount eq 0>
   <cfset nMaxOrderID = 1>
<cfelse>
   <cfset nMaxOrderID = GetNewOrderID.nMaxOrderID>
</cfif>

<cfquery datasource="#Application.DataSource#" username="xx" password="cccc" name="test4">
          UPDATE orderhistory
          SET orderhistory.OrderID = <CFQUERYPARAM CFSQLTYPE="CF_SQL_NUMERIC" VALUE="#nMaxOrderID#">
          WHERE orderhistory.OrderID = 0
          AND orderhistory.itemoid <> 0
 </cfquery>

PS: i would suggest that you don't do it this way, could u explain your requirement and why you are updating the table and not inserting.

Regards
Hart

could you just do it in one query?

<cfquery datasource="#Application.DataSource#" username="xx" password="cccc" name="test4">
UPDATE orderhistory
SET orderhistory.OrderID = (SELECT MAX(OrderID) as MaxOrderID FROM itemlist)
WHERE orderhistory.OrderID = 0
AND orderhistory.itemoid <> 0
</cfquery>

jyokum : again if the max returned is null, won't the query give an error.
the idea is good if u incorporate the isnull into it :-)

I don't know that it would give an error but it would set the value to null... which may or may not be a good thing

I agree with jyokum - a lot of suggestions were made and there was never any responses from finnstone.

The experts should be given a chance to respond and further I do not see why it would be PAQ/refund since finnstone never said that it was sovled nor posted any solution...
