ID VALUE1 VALUE2
001 1000 7777
002 9999 7777
003 7777 3000
004 9999 4000
005 6000 9999

// I need to find the rows that have duplicates BOTH in VALUE1 and VALUE2. Could anyone tell me what the correct SQL statement should be?

so the output should be like:

duplicate FOUND ---> 7777
ID VALUE1 VALUE2
001 1000 7777
002 9999 7777
003 7777 3000

duplicate FOUND ---> 9999
ID VALUE1 VALUE2
002 9999 7777
004 9999 4000
005 6000 9999

where case when v1 in(select distinct v2 from <Table>) then 1
when v2 in(select distinct v1 from <Table>) then 1 else 0 end=1
