SQL and VBE

[supertsik]

Hi! I need help with the following:

Even though it is quite easy to run SQL UPDATE queries in VBA using the DoCmd.RunSQL, I cannot find a way to run SELECT queries and use the result.

I have a table with customer names and orders. I want to store the latest orderID of a particular customer in a local variable.

In short, I would like to run this:

Private orderid as integer

orderid = {the result from the query below}
{SELECT Top 1 Orders.OrderID FROM Orders WHERE Order.customer = "Mr x" ORDER BY Orders.OrderID DESC;}

Thanks!

Since your only looking to return one value a domain aggregate will work.
Either accesses built in dmax or I like to use Allen Browne’s Elookup.
They should both yeild identical results in this case, Allen Browne explains the subtle differences at his website.

orderid = Dmax(“[OrderID]”, “[Orders]”, “[customer] = ‘Mr x’”)
or
orderid = Elookup(“[OrderID]”, “[Orders]”, “[customer] = ‘Mr x’”, "[OrderID] DESC"

hope this helps,
Megan
