extract Unique Records from multipe columns

Here's a VBA way. Select area then run

Sub ExtractDuplicateRecords()
Dim c As Range
Dim i As Long
i = Selection.Columns.Count + 1
Application.ScreenUpdating = False
For Each c In Selection
If Application.CountIf(Columns(i), c) = 0 Then
Cells(65536, i).End(xlUp).Offset(1, 0) = c
End If
Next c
With Cells(1, i)
.Value = "Unique List"
.EntireColumn.AutoFit
End With
Application.ScreenUpdating = True

End Sub

Here's an example demonstrating an approach you may be interested in:

Assumptions:
Sheet1 contains your data in cells A1:B10
Sheet2 is where you want the extracted data to be displayed

Using Sheet2:
A1: EmpID
B1: Age

Insert>Name>Define
Names in workbook: Sheet2!Extract
Refers to: =Sheet2!$A$1:$B$1

I1: EmpID
I2: 24

Insert>Name>Define
Names in workbook: Sheet2!Criteria
Refers to: =Sheet2!$I$1:$I$2

Still using Sheet2:
Insert>Name>Define
Names in workbook: Sheet2!Database
Refers to: =Sheet1!$A$1:$B$10

(Notice: you are on Sheet2, and creating a Sheet2-level range name, but
the referenced range is on Sheet1)

The reason: An advanced filter cannot SEND data to another sheet, but
it can PULL data from another sheet.

Now...set up the Advanced Data Filter:
<Data><Filter><Advanced Filter>
Select: Copy to another location
List Range: (press F3 and select Database)
Criteria Range: (press F3 and select Criteria)
Copy To: (press F3 and select Extract)
Click [OK]

Note: if you want to run that Advanced Data Filter repeatedly,
you'll need to re-select Database each time
....OR...if you're feeling a bit ambitious...

You can build a simple macro to automatically re-run the filter:
Press [Alt]+[F11] to open the VBA editor
Right click on the VBA Project folder for your workbook
Select: Insert>Module

Then, copy/paste this code into that module:

PHP Code: 

Option Explicit
Sub PullMatchingData()
Range("Sheet2!Database").AdvancedFilter _
Action:=xlFilterCopy, _
CriteriaRange:=Range("Sheet2!Criteria"), _
CopyToRange:=Range("Sheet2!Extract"), _
Unique:=False
End Sub 


To run the code:
Tools>Macro>Macros (or [Alt]+[F8])
Select and run: PullMatchingData

To test, change the value of I2 and run it again.

Is that something you can work with?
