在MS Access中，我需要查找记录并将其用作报告的“控制源”

Question

My situation is that I need to pull an additional name for a report. The name I need has to match a specific employee ID .

I read that I could use =DLookup() to do this but I am getting a problem. Here is my current attempt at solving this problem.

I set up a query called [EE Query] with the contents

SELECT Employees.FirstName, Employees.LastName 
FROM Employees WHERE (((Employees.ID)=[Escalations].[EE]));

In my report I used the following as my control source in the desired field "=DLookUp([FirstName],[EE Query])"

So when I run my report, I get an input box that asks me to enter a value for "EE Query" . I find this strange as that isn't a parameter.
So I assumed maybe I messed up and it was asking for a value for [Escalations].[EE] however when I entered the ID for the desired EE, my textbox shows "#Error"

I do not know where I went wrong.

Also if it helps here is my Record Source for the report, keep in mind that the FirstName field in this refers to a TSE and not to the needed EE.

SELECT [Report Query].DateTime, [Report Query].EscalationNeed, 
[Report Query].EscalationOutcome, Employees.FirstName, Employees.LastName, 
[Report Query].TSE, [Report Query].EE
FROM Employees INNER JOIN [Report Query] 
ON Employees.[ID] = [Report Query].[TSE];

[Escalations] [Employees] [Titles] are all tables. Access 2010

Answer 1

Here are two different solutions

SOLUTION 1 - in VBA

---

This solution can be useful if you need to create text box dynamically. In the Form_Open event add this 3 lines of code

Dim s As String
s = "=DLookup(""FirstName"",""Employees"",""(Employees.ID)=[Escalations].[EE]"")"
txtYourTextBox.ControlSource = s

SOLUTION 2 - Directly in the interface

---

Set ControlSource property of your control to =DLookup("FirstName";"Employees";"Employes.ID=Escalations.EE")

WARNING

Please, note that there is a fundamental difference (:-() when you use VBA and the interface: the separator between the arguments in the 1st case is comma (,), in the 2nd case is the semicolomn (;).

Answer 2

I have not solved the actual problem but I changed my DB design so that it is easier to work with in access.

To do this I created a separate table for the EE and TSE type employees so that I could easily include the names of each in the record source for my report. I then set the needed boxes to the now available Control Source fields for the EE name.
