SQL BETWEEN is a conditional operator that is used to select values within a specified range. It is used in SQL queries to filter data based on a range of values. The BETWEEN operator is used with the WHERE clause to specify the range of values to be selected.
The syntax for using SQL BETWEEN is as follows:
SELECT column_name(s) FROM table_name WHERE column_name BETWEEN value1 AND value2;
In this syntax, column_name is the name of the column in the table that we want to filter, table_name is the name of the table containing the column, value1 is the lower limit of the range, and value2 is the upper limit of the range.
The BETWEEN operator is inclusive, meaning that it will include the lower and upper limits in the result set. If we want to exclude the lower or upper limit, we can use the greater than (>) or less than (<) operators.
Here is an example of using the SQL BETWEEN operator:
SELECT * FROM customers WHERE age BETWEEN 18 AND 25;
This query will select all the rows from the customers table where the age column is between 18 and 25 (inclusive). It will exclude any rows where the age is less than 18 or greater than 25.
In conclusion, SQL BETWEEN is a powerful operator that allows us to filter data based on a range of values. It is an essential tool for data analysts and database developers who need to retrieve specific data from large datasets.
