Qlik Sense - duplicate values

[Anonymous]

I have loaded data by using SQL and have the table loaded as given below:

Col1                Col2

APPLE            RED

APPLE           GREEN

ORANGE       YELLOW

BANANA         BLACK

GRAPES         PURPLE

GRAPES          VIOLET

1. Let me know how to write the expression to see the duplicate values in a table as seen below

Col1                    Col2

APPLE                RED

APPLE           GREEN

GRAPES         PURPLE

GRAPES          VIOLET

2. Also need another expression to view all the records with a new column added as seen below:

Col1                Col2             Col3

APPLE            RED               Duplicate   

APPLE           GREEN           Duplicate  

ORANGE       YELLOW         No Duplicate  

BANANA         BLACK           No Duplicate  

GRAPES         PURPLE        Duplicate  

GRAPES          VIOLET         Duplicate

Both have two dimensions Col1 and Col2.

The first table has the expression:

If(Count(TOTAL <Col1> Col1)>1,' ',Null())    or simply    If(Count(TOTAL <Col1> Col1)>1,' ')

and the label:

=' '

Finally on the Add-Ons remove the checkmark for "Include zero values"

The second table has the expression:

If(Count(TOTAL <Col1> Col1)>1,'Duplicate','No Duplicate')

and the label:

=' '
