What is the role of mysql_query in conjunction with mysql_insert_id in PHP when inserting data into a database?

When inserting data into a database using PHP, `mysql_query` is used to execute the INSERT query, while `mysql_insert_id` is used to retrieve the auto-generated ID (if any) from the last query. This is useful when you need to get the ID of the last inserted record for further operations or to establish relationships between tables. 

// Insert data into the database
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
mysql_query($query);

// Get the auto-generated ID of the last inserted record
$last_insert_id = mysql_insert_id();
