MySQL Select Statement – Fetching Data from MySQL Databases

SQL Select

The MySQL SELECT statement forms a part of the Data Query Language (DQL) in SQL, which deals with fetching data.

Suppose you are putting on a science exhibition. To decide upon which exhibits (or projects) to put on display in the exhibition, you would first select a project and then put it for display.

Similarly, when you make a table in SQL, you would want to display the data in it at some point. The SELECT statement does that for you. It selects the data by fetching it from the database and then displays it in a tabular form. This output retrieved in a tabular format is known as a result-set.

Syntax of the MySQL SELECT Statement

The syntax of the SELECT statement is as follows:

SELECT expressions FROM table_names;

The expression can be catered to your needs, such that –

  1. If you want to retrieve all the columns of the table, use *.
  2. If you want to retrieve only a few columns, mention the column names separated by a comma.

How to Use the MySQL SELECT Statement?

Let us now explore a few examples of the SELECT statement. We’ll consider the following ‘Students’ table.

Mysql Student Table
Students Table

1. Displaying All Columns

If you wish to display the Students table in the above format, you can do the following:

SELECT * FROM Students;

2. Displaying Particular Columns

If you wish to display only the FirstName column from the Students table, you can do the following:

SELECT FirstName FROM Students;

The output will look like this:

Sql Select One Column

Similarly, you can display multiple columns. If you want to output only the ID and DaysPresent columns from the Students table, we will select only those columns. It can be done as follows:

SELECT ID, DaysPresent FROM Students;

Your output will look like this:

Sql Select Multiple Columns

As you can see, the query returns only the ID and the DaysPresent columns from the Student table in the result-set. If your dataset contains duplicate values and you wish to display only distinct values, you can use the DISTINCT clause.


The SELECT statement is one of the most used and versatile statements in MySQL, and in the coming tutorials, we will see how we can use it for different operations.
