Can you explain the between clause

by

Below SQL selects employees born between ’01/01/1975′ AND ’01/01/1978′ as per mysql

SELECT * FROM pcdsEmployee WHERE DOB BETWEEN ‘1975-01-01’ AND ‘2011-09-28’

Sure, the BETWEEN clause in a database management system (DBMS) is used to specify a range to test against. It’s commonly used in SQL queries to filter data within a specified range of values.

Here’s how it works:

sql
SELECT column_name(s)
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
  • column_name: The column you want to test against.
  • table_name: The table containing the column.
  • value1 and value2: The range of values you want to test against.

The BETWEEN clause includes value1 and value2. So, if you want to find values within a range but exclude the boundary values, you may need to adjust your query accordingly.

For example:

sql
SELECT *
FROM employees
WHERE age BETWEEN 25 AND 40;

This query would return all records from the “employees” table where the “age” column falls between 25 and 40, inclusive.

Keep in mind that the BETWEEN clause is inclusive, meaning it includes the values specified. If you need to exclude the endpoint values, you can use comparison operators (< and >) instead.
