How to Delete Duplicate Records in MS Access

Описание: We all eventually end up working on some table that someone designed that has no primary key, and has tons of duplicates. Luckily, we can use a few powerful techniques to either get unique rows out of that table (1 of 2: extract), or we can use some coding techniques to use the power of sorting with the ability to look at previous and current rows to identify and delete problem rows (2 of 2: delete). The two techniques in this video are very powerful for data cleaning and wrangling, and will definitely help you in cases where uniqueness is a problem in the data.
