Access tables are used for storing the information and forms are used for entering the data into the database in a very user friendly way. But there are also other useful Access objects, which allos us perform different useful tasks with the data. After we enter the data into the database it is often needed to get it out for different purposes.

This kind of task can be performed via using MS Access database queries.

This takes a lot of time, effort and simply impractical, especially if you have thousands of records in your database. A much faster and logical approach is to run a query to perform this task for you. In order to create a query, you should get into the query designer and choose the tables containing the required data. After you have found the tables, you should drag the needed fields into special grid. There is also a criteria line, where you can enter any necessary criteria for a field. This way you can restrict certain criteria like region or others.

Queries work fast and will pull the necessary data almost instantly, depending on the amount of data stored and it needs to look through for producing the required results. This is what Access select queries do, but there are also many other queries for us to choose from. We can also choose to run action queries. These queries are used when there us a requirement to update the database data, append it or remove it. All this can be done using the action query. Besides the select and the action query, there is also a make table query, which is actually a part of action queries. We might decide to put certain data into a separate table, so we can run a make table query, which will create a new table with the needed data from the other table or query. You can also add certain criteria for restricting the data you need.
