Use DLookup to Look Up a Value from a Table

 S  M  L  XL  FS  Join Now

In this video, I'll show you how to use the DLookup function to look up a value from a table or query. We will look up a sales rep's phone number based on his ID.

Mitchell from Akron, Ohio (a Gold Member) asks: Each of my customers have an assigned sales rep. I've got the rep's name displayed in a combo box on the customer form. Is there a way that I could have his phone number appear next to it so I don't have to keep clicking and loading different forms? I tried making the phone number the second column in the sales rep combo box, but people still have to click to open it up to see it, and sometimes people accidentally change the rep. I just want the phone number to appear next to his name in a text box.

Common Formats

  • DLookup("Field", "Domain", "Criteria")
  • DLookup("FirstName", "CustomerT", "CustomerID=5")
  • DLookup("FirstName", "CustomerT", "CustomerID=" & CustomerCombo)
  • DLookup("StateName", "StateT", "StateAbbreviation=""" & State & """")
  • DLookup("OrderID", "OrderT", "OrderDate=#" & LastOrderDate & "#")
  • DLookup("CustomerID", "CustomerT", "FirstName=""" & FN & """ AND LastName=""" & LN & """")


Members will learn how to handle DLookup criteria involving text strings and dates and use NZ to deal with NULL values. We will learn about AND/OR conditions in criteria. We will see how to use DLookup with DMax and DSum to get the date and amount of a customer's most recent order.

Hi all,

Can you create a Dlookup based on the different criteria's? So for example I have a flange register, on that register there is a field for torque value. Now this value can change if the bolt size is different, if the gasket is different or if the bolt material is different. Each one of these has a separate field also. Is there a way of doing a dlookup so if the flange is a 1" 150# with B8 bolts that are 1/2" and the gasket is spiral wound the torque figure = 100lbft Read More...

Did you try the Common Formats from above?
DLookup("CustomerID", "CustomerT", "FirstName=""" & FN & """ AND LastName=""" & LN & """")

Yes it is possible. However,  You can only look up what you already have in the table or query you are looking up from.

also look into the Search Seminar

I see that you have started the Beginner Series and some of this is pretty complicated if you don't have a good base to work from.
Keep following the courses in order to make sure you develop that base.

You could use DLookup in combination with an AfterUpdate

I'm trying to wrap my head around using the columns in a combo box.  Just finished watching this video and also Developer 15 where you use .Column(0,x) in an example in lesson 3. Read More...

Yes, Scott, you could absolutely use the second column from the combo box, however the point was to show DLookup. In THIS case it would work, but you can't load certain values into a combo box (like Long Text) and you may want to DLookup more values than you would normally put into the combo box, or even not know which field you want to look up until runtime. Hence, DLookup.

.Column(0,x) is just another way of saying Column Y, Row X. It's used for List Boxes.
