To delete duplicate records in MS Access using an SQL query, you can follow these steps:
Duplicate records corrupt your data integrity and skew reports, making business decisions unreliable. While you could manually hunt through thousands of rows, SQL queries let you identify and remove duplicates in seconds based on specific criteria you define.
This approach also creates an audit trail of what was deleted, unlike manual deletion. More importantly, you can target partial duplicates where only certain fields match, preserving legitimate records that might look similar but represent different entities or transactions.
