If you’re familiar with SQL, you probably know that the SELECT statement is used to fetch data from a database. However, there are various operators that you can use with the SELECT statement to refine and manipulate the data you retrieve. In this blog post, we’ll explore some of the most commonly used SQL SELECT operators.

1. DISTINCT

The DISTINCT operator is used to eliminate duplicate rows from the result set. It ensures that only unique values are returned for a specific column. Here’s an example:

SELECT DISTINCT column_name
FROM table_name;

2. WHERE

The WHERE operator allows you to filter specific rows based on a given condition. It uses comparison operators such as = (equal), <> (not equal), > (greater than), < (less than), and more. Here’s an example:

SELECT column_names
FROM table_name
WHERE condition;

3. ORDER BY

The ORDER BY operator is used to sort the result set in ascending (ASC) or descending (DESC) order. By default, it sorts the result set in ascending order. Here’s an example:

SELECT column_names
FROM table_name
ORDER BY column_name ASC;

4. LIMIT

The LIMIT operator is used to restrict the number of rows returned by a query. It can be useful when you only need a subset of the result set. Here’s an example:

SELECT column_names
FROM table_name
LIMIT number_of_rows;

5. GROUP BY

The GROUP BY operator is used to group rows based on the values in a specific column. It is often used in conjunction with aggregate functions such as SUM, COUNT, AVG, etc. Here’s an example:

SELECT column_names
FROM table_name
GROUP BY column_name;

These are just a few of the SQL SELECT operators that can enhance your querying capabilities. By applying these operators effectively, you can manipulate and retrieve the data you need from your database more efficiently.
