What are some functions or methods in MySQL that can be used to limit and extract specific parts of data?

To limit and extract specific parts of data in MySQL, you can use functions like LIMIT, OFFSET, and SUBSTRING. LIMIT allows you to specify the maximum number of rows to return, while OFFSET lets you skip a certain number of rows before beginning to return results. SUBSTRING can be used to extract a specific portion of a string.

// Example using LIMIT and OFFSET to extract specific parts of data
$query = "SELECT * FROM table_name LIMIT 10 OFFSET 5";
$result = mysqli_query($connection, $query);

// Example using SUBSTRING to extract specific parts of a string
$query = "SELECT SUBSTRING(column_name, 1, 5) FROM table_name";
$result = mysqli_query($connection, $query);
