• The columns to be retrieved are specified within the SELECT remark.

• The BETWEEN operator is used within the WHERE clause. The column we need to observe the variety situation on is specified within the “column_name” parameter. The beginning worth of the variety of values is specified within the “range_start” parameter and the finishing worth within the “range_end” parameter.

As an example, let’s take a pattern “Employeedetails” desk:

From this desk, if we need to retrieve the ID and title of the workers with ID within the vary of four to 7, we’ll use the next question:

This will likely outcome within the following:

As we will see, the outcome comprises ID values 4 and seven as neatly, as Between is inclusive.

The use of the Now not Operator With Between

We will additionally use the NOT operator with the BETWEEN operator to make a choice the values that don’t belong to the required vary. That is accomplished by means of the use of the NOT BETWEEN key phrase as a substitute of the BETWEEN key phrase within the above syntax. 

As an example, from the pattern desk, if we need to retrieve all of the staff’ ID and wage, with the wage now not within the vary 30000 to 80000, we’ll use the next question:

This will likely outcome within the following:

The use of Between With Numeric Values

We will use the ORDER BY remark to type the outcome in accordance with some columns.

This will likely outcome within the following:

The use of Between With Date Values

This will likely outcome within the following:

• Let’s see what occurs once we don’t enclose the information in inverted commas:

As we will see, the question returns a syntax error.

• We will additionally make a selection the values that don’t belong to the values specified within the parentheses by means of the use of the NOT IN key phrase as a substitute of the IN key phrase.
