Hour 15. Power Query Techniques > Creating and Running Action Queries

Creating and Running Action Queries

With Action queries, you can easily modify data without writing any code. In fact, using Action queries is often a more efficient method of modifying data than using code. Four types of Action queries are available: Update, Delete, Append, and Make Table. You use Update queries to modify data in a table, Delete queries to remove records from a table, Append queries to add records to an existing table, and Make Table queries to create an entirely new table. The sections that follow explain these query types and their appropriate uses.

Creating and Running Update Queries

You use Update queries to modify all records or any records that meet specific criteria. You can use an Update query to modify the data in one field or several fields (or even tables) at one time. For example, you could create a query that increases the salary of everyone in California by 10%. As mentioned previously, using Action queries, including Update queries, is usually more efficient than performing the same task with Visual Basic for Applications (VBA) code, so you can consider Update queries a respectable way to modify table data.
