Final answer:
Selecting all or part of a field value in a datasheet and then applying a filter in a database allows you to display only those records that have the selected value. The filter narrows down the dataset based on the selected criteria, but it does not delete or update any records. It simply sorts the records that meet the filter condition.
Step-by-step explanation:
Selecting all or part of a field value in a datasheet and then applying a filter in a database allows you to display only those records that have the selected value. This helps in finding specific information or analyzing data more effectively. The filter narrows down the dataset based on the selected criteria, but it does not delete or update any records. It simply sorts the records that meet the filter condition.
