If the record has a zip code that matches the lookup table, its City and State fields are replaced. Any built-in VBA function that returns a value can be used as the update value.

Any public function that you create in a standard module can be used in a query. Your field is updated with the return value of the function. If your function takes parameters, you can pass field values as parameters and the function executes for each record that is processed. If an Update Query fails to modify the table's data, the first thing to verify is that the underlying table is updateable. Simply open the table and manually try to edit the field. If you can't do it manually, the query can't make the change either.

This can be due to several reasons:. Assuming you can edit your table, your query may fail and display this error message when you run it:. Operation Failed. If so, check out our paper on Error Operation must use an updatable query: Dealing with Non-Updateable Queries and the Use of Temporary Tables in Microsoft Access which discusses some of the issues and workarounds. They are extremely powerful and eliminate a lot of manual updates and unnecessary coding. They are also much easier to maintain and debug than module code.

When confronted with the limitations of what you can do with SQL Syntax, you can supplement Access update queries with your own functions letting Access take care of updating the records, while you focus on the calculations.

Now you need to convert the Select query to an Update query. This query modifies and updates the records in your tables using your custom criteria. For example, if you want to change the country for all your users in Germany to the US, you can create a custom criterion that automatically finds the required records and updates them for you.

If you want to remove certain records from your tables, a Delete query can help you do that. This query deletes the rows from your tables that match the given criteria. This solution will show you how to do just that. If you can join the two tables on some common field or combination of fields, you can use an update query to update a field in one table based on the values found in a second table. Here are the steps to create an update query that updates values across tables:. Create a standard Select query.

Add the two tables to the query and join them on the common field or fields. In the sample database, we added the tblAlbums and tblAlbumsUpdated tables to the query. We will refer to tblAlbumsUpdated as the source table because it will supply the values to be used to update the other table; tblAlbums is the target table because it will be the target of the updates. Access has automatically joined the two tables on AlbumID.
