SQL (Structured Query Language) is a programming language used to manage and manipulate relational databases. One of the most commonly used SQL operators is the BETWEEN operator. The BETWEEN operator is used to select values within a range of values. It is a very useful operator when working with databases that contain a large amount of data.
The BETWEEN operator is used to select values within a range of values. It is used in the WHERE clause of a SQL statement to filter data based on a range of values. The BETWEEN operator is inclusive, meaning that it includes the start and end values in the range. The syntax for the BETWEEN operator is as follows:
SELECT column_name(s) FROM table_name WHERE column_name BETWEEN value1 AND value2;
In the above syntax, column_name is the name of the column you want to retrieve data from, table_name is the name of the table you want to retrieve data from, value1 is the starting value of the range, and value2 is the ending value of the range.
Let's take a look at some examples of how to use the BETWEEN operator in SQL:
Select all records from the "customers" table where the "age" column is between 18 and 30:
SELECT * FROM customers WHERE age BETWEEN 18 AND 30;
Select all records from the "orders" table where the "order_date" column is between '2021-01-01' and '2021-12-31':
SELECT * FROM orders WHERE order_date BETWEEN '2021-01-01' AND '2021-12-31';
Select all records from the "employees" table where the "salary" column is between 50000 and 100000:
SELECT * FROM employees WHERE salary BETWEEN 50000 AND 100000;
The BETWEEN operator is a very useful operator when working with databases that contain a large amount of data. It allows you to filter data based on a range of values, which can be very helpful when trying to retrieve specific data from a database. By using the examples provided in this tutorial, you should now have a good understanding of how to use the BETWEEN operator in SQL.
