In the LanguageArtsClasses database an append query was used to add partial records to assist in recording the scores for an assignment. If that query was accidentally run twice, there would be duplicate records. How can we find and remove such duplicate records??
Access has a wizard for creating a query that finds duplications. The datasheet will show both sets of records.
Once you have created the Find Duplicates query, a little inspection of
the datasheet shows where the duplicate records start. (Score ID 9619 and
larger in this case.)
Now we can add a criteria to pick out those records and turn the query into a Delete query.
When you run the delete query, a message appears, telling you how many records you are going to delete. There should be 92 for this query.
Remember... You cannot Undo a delete query's action.
