I tried using the following SQL Script to find out duplicate records in a table
SELECT COUNT(Per_ID)
FROM TableName
HAVING COUNT(Per_ID) 1
group BY Per_ID
However I could not get the SQL Script working. Can somebody please help me....

Original:
SELECT COUNT(PER_ID) FROM TABLE_NAME HAVING COUNT(PER_ID) 1 GROUP BY PER_ID
I think its just the structuring, try
SELECT COUNT(PER_ID) CNT FROM TABLE_NAME GROUP BY PER_ID HAVING CNT 1
