I have a table with 2 columns, code and country. Code is 9 characters. I would like to find all the rows in the table where the first 8 char plus the country are duplicates.
123456781  AG
123456782  AG
123456781  BB
987654321  JM

would have concatentated values

which has the duplicate value 12345678AG
so I want to get only the records where the concatenated values are duplicated.

123456781  AG
123456782  AG

I have used concatenation only to describe the problem.
I am fine if the solution can select these same record without concatenation.
