Question

What are queries,when do we need to apply criteria in queries.​

Answer 1

Explanation:

When you want to limit the results of a query based on the values in a field, you use query criteria.

A query criterion is an expression that Access compares to query field values to determine whether to include the record that contains each value.

Some criteria are simple, and use basic operators and constants. Others are complex, and use functions, special operators, and include field references.

To add some criteria to a query, you must open the query in the Design View.

You then identify the fields for which you want to specify criteria.

Example

Let’s look at a simple example in which we will use criteria in a query. First open your Access database and then go to the Create tab and click on Query Design.
