Recordsets are objects that represent collections (sets) of records.

Recordsets have many methods and properties to make working with the records in the collection easy.

Instead, a typical Access database is a a collection of tables, plus a set of objects built around those tables — forms, reports, queries, and so on.

In addition, those objects must adhere to a set of design principles or the database will either work poorly or fail altogether.

The code below opens a recordset taken from a table in the current database on a query or attached table Access defaults the Type property to db Open Dynaset.

Microsoft Office Access 2007 provides a number of tools for updating existing records, including datasheets, forms, queries, find-and-replace, and the new Data Collection feature.

To add new records to a database you use an append query, and to delete whole records from a database you use a delete query.

Large updates become much easier to perform when you understand some of the basic principles of database design.

An Access database is not a file in the same sense as a Microsoft Office Word 2007 document or a Microsoft Office Power Point 2007 slide deck.

Access tries very hard to make things easy for you. When you create a query, you start out by constructing a SELECT query (using the Query Design View, which shows a grid with rows for Field:, Table:, Criteria: and so on).

You can then use a toolbar or ribbon button to "convert" the query to an UPDATE query, which changes some of the rows in the grid (in particular, you get an Update To: row).

For this reason it is safer to just generally stick to db Open Dynaset.

To add a new record a recordset has to be be available.

As a best practice, there are two main steps that you must follow to create and run an update query: create a select query that identifies the records that you want to update, and then convert that query to an update query that you can run to update the records.

Tip: You might want to back up your database before you run an update query.

UPDATE summary_data SET current_category = (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id) WHERE EXISTS (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id); If you want to test your skills using the SQL UPDATE statement, try some of our practice exercises.
