have duplicate records in application using sql as db. No
ability in application to remove duplicate data.

Need a query to find all duplicate records, or records
created within a date\time range will do as well,
then how to delete\remove them from sql.

you can use following query as guidelines to find duplicate records

SELECT columnname, count(*)
FROM dbo.tablename
GROUP BY columnname
HAVING count(*) > 1

There are some articles in following site for finding and removing
duplicates
in database
