this simple query is supposed to add records from itemlist table into orderhistory table, can anyone tell me why it does not work anymore now that i have moved the db from access to sql

            <cfquery datasource="#Application.DataSource#" username="x" password="x" name="test3">
      UPDATE itemlist
      LEFT JOIN orderhistory ON itemlist.itemlistoid = orderhistory.itemlistoid
      SET orderhistory.itemlistoid = itemlist.itemlistoid, orderhistory.useroid = itemlist.useroid, orderhistory.cartoid = itemlist.cartoid, orderhistory.itemoid = itemlist.itemoid, orderhistory.itemlistselection = itemlist.itemlistselection, orderhistory.itemquantity = itemlist.itemquantity;

change the update statement to

UPDATE itemlist
SET orderhistory.itemlistoid = itemlist.itemlistoid, orderhistory.useroid = itemlist.useroid, orderhistory.cartoid = itemlist.cartoid, orderhistory.itemoid = itemlist.itemoid, orderhistory.itemlistselection = itemlist.itemlistselection, orderhistory.itemquantity = itemlist.itemquantity
from itemlist
     LEFT JOIN orderhistory ON itemlist.itemlistoid = orderhistory.itemlistoid

i don't see u inserting records, u r updating the table..

just try the following query

insert into orderhistory (itemlistoid, useroid, cartoid, itemoid , itemlistselection , itemquantity)
as select itemlistoid, useroid, cartoid, itemoid , itemlistselection , itemquantity from itemlist

Actually you can write it even simpler as :

INSERT INTO orderhistory SELECT itemlistoid, useroid, cartoid, itemoid, itemlistselection, itemquantity FROM itemlist

which will insert all of the columns from itemlist into the orderhistory table
You don't need to specify fields unless there are fields that do not match.

If you want to update orderhistory then maybe this:

Update orderhistory <!--- Not itemlist --->
SET orderhistory.itemlistoid = itemlist.itemlistoid, orderhistory.useroid = itemlist.useroid, orderhistory.cartoid = itemlist.cartoid, orderhistory.itemoid = itemlist.itemoid, orderhistory.itemlistselection = itemlist.itemlistselection, orderhistory.itemquantity = itemlist.itemquantity
From itemlist  LEFT JOIN orderhistory ON itemlist.itemlistoid = orderhistory.itemlistoid
