The four main types of queries are select queries, action queries, parameter queries, and aggregate queries. Select queries retrieve data from one or more tables based on specified criteria. Action queries modify data, such as updating, deleting, or inserting records. Parameter queries prompt users for input to filter results dynamically, while aggregate queries perform calculations on data, such as summing or averaging values.
Queries can be categorized into several types based on their purpose and structure. The primary types include select queries, which retrieve data from databases; action queries, which modify data (like insert, update, or delete); parameter queries, which prompt users for input to filter results; and aggregate queries, which perform calculations on a set of values, such as summing or averaging. Additionally, there are join queries, which combine data from multiple tables based on related columns.

A query is formulated to retrieve data that meets the query parameters. For example if you had a data base containing peoples names and ages, a query might be to retrieve all names who have an age between 25 and 30.
In Access, the best types of queries for data analysis are Aggregate Queries, which summarize data using functions like SUM, AVG, and COUNT; Parameter Queries, which allow users to input criteria dynamically; and Crosstab Queries, which provide a compact summary of data across two dimensions. Using these queries enables efficient extraction of insights from large datasets, facilitating informed decision-making. Additionally, Action Queries can be useful for data manipulation tasks such as updating or deleting records based on specific criteria.
The query wizard can only do a limited set of types of queries. There are some kinds of queries that it cannot create. Some kinds of queries can only be done in SQL. Union queries and data definition queries for example. It is more complicated to do queries in SQL, but you can do more powerful ones. The query wizard is just for simple queries or for getting a basic query which you can then enhance using the design grid or SQL.
The outer union operation in database queries combines the results of two queries, including all rows from both queries. This differs from other types of joins, like inner joins, which only include rows that have matching values in both tables. Outer union can help retrieve data from multiple tables even if there are no matching values, providing a more comprehensive view of the data.
