What are the main uses of Macros in Access and once you have learnt how to use VBA, do you need to use them again?

Hi Chloe

Thank you for your question

Macros allow the developer to build a simple set of automated steps, thus improving the efficiency of a database application.

Once a developer is competent in VBA however Macros have very little utility. They cannot carry out the range of methods available in VBA and in general run a lot slower than the corresponding VBA code
Regards

Access tip:

Deleting duplicate records from a table

You cannot delete records tables where there duplicate records. A way around this is to create a new table which wont hold the duplicates. and then deleting the old table.

1. Use a make-table query based on this table only. IMPORTANT - Ensure that you include all of the fields from your original table or you may loose data.

2. Open the query's property sheet by using VIEW, QUERY, PROPERTIES, and set the Unique Values property to Yes

3. Because you have selected the Unique Values to Yes when you run the query, Access creates a new table without duplicate records. You can now delete the old table and rename the new one.
