MySQL - Select Query

The SQL SELECT command is used to fetch data from the MySQL database. You can use this command at mysql> prompt as well as in any script like PHP.


Here is generic SQL syntax of SELECT command to fetch data from the MySQL table −

SELECT field1, field2,...fieldN 
FROM table_name1, table_name2...
[WHERE Clause]
  • You can use one or more tables separated by comma to include various conditions using a WHERE clause, but the WHERE clause is an optional part of the SELECT command.

  • You can fetch one or more fields in a single SELECT command.

  • You can specify star (*) in place of fields. In this case, SELECT will return all the fields.

  • You can specify any condition using the WHERE clause.

  • You can specify an offset using OFFSET from where SELECT will start returning records. By default, the offset starts at zero.

  • You can limit the number of returns using the LIMIT attribute.

Fetching Data from a Command Prompt

This will use SQL SELECT command to fetch data from the MySQL table tutorials_tbl.


The following example will return all the records from the tutorials_tbl table −

root@host# mysql -u root -p password;
Enter password:*******
mysql> use TUTORIALS;
Database changed
mysql> SELECT * from tutorials_tbl 
| tutorial_id | tutorial_title | tutorial_author | submission_date |

Fetching Data Using a PHP Script

PHP uses mysqli query() or mysql_query() function to select records from a MySQL table. This function takes two parameters and returns TRUE on success or FALSE on failure.



Sr.No. Parameter & Description


Required - SQL query to select records from a MySQL table.



Optional - Either the constant MYSQLI_USE_RESULT or MYSQLI_STORE_RESULT depending on the desired behavior. By default, MYSQLI_STORE_RESULT is used.


Try the following example to select a record from a table −

Copy and paste the following example as mysql_example.php −

      <title>Creating MySQL Table</title>
         $dbhost = 'localhost';
         $dbuser = 'root';
         $dbpass = 'root@123';
         $dbname = 'TUTORIALS';
         $mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname);
         if($mysqli->connect_errno ) {
            printf("Connect failed: %s<br />", $mysqli->connect_error);
         printf('Connected successfully.<br />');
         $sql = "SELECT tutorial_id, tutorial_title, tutorial_author, submission_date FROM tutorials_tbl";
         $result = $mysqli->query($sql);
         if ($result->num_rows > 0) {
            while($row = $result->fetch_assoc()) {
               printf("Id: %s, Title: %s, Author: %s, Date: %d <br />", 
         } else {
            printf('No record found.<br />');


Access the mysql_example.php deployed on apache web server and verify the output. Here we've entered multiple records in the table before running the select script.

Connected successfully.
