How to use SQL BETWEEN

What is BETWEEN?

BETWEEN is an operator in SQL that checks whether a value is between two values ​​(including these two values).

grammar

BETWEEN start_value AND end_value

in:

• start_value is the start value (inclusive).
• end_value is the end value (inclusive).

How to use

To use the BETWEEN operator, follow these steps:

1. In the query, specify the column to check.
2. Use the BETWEEN operator to specify the start and end values.

Example

The following query finds all orders created between 2023-01-01 and 2023-03-31 :

 <code class="sql">SELECT * FROM orders WHERE order_date BETWEEN '2023-01-01' AND '2023-03-31';</code>

Things to note

• The start value and the end value can be of the following types: date, time, number, string, etc.
• The value must match the value type in the compared column.
• The BETWEEN operator includes the start value and the end value.
• If start_value > end_value, the BETWEEN operator returns an empty result set.
• The results of the BETWEEN operator can be reversed by using the NOT operator. For example:

 <code class="sql">SELECT * FROM orders WHERE NOT order_date BETWEEN '2023-01-01' AND '2023-03-31';</code>

This will look for all orders not created between 2023-01-01 and 2023-03-31 .
