Use DLookup to Look Up a Value from a Table


 S  M  L  XL  FS  |  Slo  Reg  Fast  2x  |  Bookmark 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

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.
