How to Select All from a Table in MySQL in 2025
MySQL continues to be one of the most popular relational database management systems due to its reliability and efficiency. As of 2025, many of the core SQL commands remain unchanged, but understanding their correct usage ensures optimal database performance. A common requirement in database operations is to select all records from a table. In this article, we will review how to use the SELECT
statement in MySQL for retrieving all rows from a table efficiently.
Understanding the SELECT
Statement
The SELECT
statement is fundamental in SQL for querying data from databases. To fetch all columns from a specified table, the syntax remains straightforward:
SELECT * FROM table_name;
Here, *
is a wildcard character indicating that all columns in the table should be included in the result set.
Step-by-Step Guide to Using SELECT *
1. Connect to the MySQL Database
Before you can execute SQL statements, you need to establish a connection to your MySQL database. If you need guidance on creating a MySQL database connection, refer to this MySQL database connection tutorial.
2. Choosing the Right Database
Once connected, make sure you have selected the correct database:
USE database_name;
3. Executing the SELECT
Query
Use the SELECT *
command to fetch all records from your desired table:
SELECT * FROM employees;
This command will retrieve all columns and all rows from the employees
table. For optimal performance, ensure that this operation is necessary, as retrieving a large amount of data can be resource-intensive.
4. Applying Conditions (Optional)
If you want to filter the results, you can add a WHERE
clause:
SELECT * FROM employees WHERE department = 'Sales';
5. Handling Large Data Sets
In scenarios where tables contain massive amounts of data, consider paginating the results or limiting the number of rows returned using the LIMIT
clause:
SELECT * FROM employees LIMIT 10;

While the command itself is simple, understanding its full implications on performance and database design is crucial. As MySQL continues to evolve, keeping updated on optimizations and best practices ensures that your data operations remain efficient and effective.
Harness the full potential of MySQL by pairing basic operations with advanced features and ensure to stay informed on updates beyond 2025.
