4. Parameter Query
5. Auto lookup Query
6. Action Query
7. Cross Tab Query.

1. Advanced filter query:

• It is the simplest kind of query
• Allows to sort and find information from a single table in the database.
• This option is available in any sheet by clicking on the Advanced in the Sort & Filter group of the Home tab.

2. Select query:

• It is the most common type of query used in Ms. Acess.
• The select query selects the data from an individual or multiple tables and displays the data according to the user's demand.
• A select query may include criteria that instruct Acess to filter the data and display some of them.
• The data returned is stored in a table called the result -set.

3. Total or Summery query :

• It is the subset of the select query which displays the total or aggregate of the tables
• It is also called a Group-By query.

4. Parameter Query:

• The parameter query prompts the end user to supply the criteria before the query is run.
• The query will show results that reflect the user's search.

5. Autolookup Query :

• It is a type of query that fills in the criteria for the user.
• To create an autolookup query it must be based on more than one table.

6. Action Query :

• Action query can change the data based on some set criteria.
• It can add, change or delete multiple records at a time.
• They can distinguish data in the database.
• Action queries allows the user to operate on the set of data and not single rows.

7. Cross Tab Query :

• A cross tab query adds, multiples, or takes out averages of the data that is categorized by row and column tables.
• This presents the summary in a compact format similar to a spreadsheet.
