Retrieving Records with Minimum Field Values in MySQL
In MySQL, you may encounter scenarios where you need to select data from a table based on a field that possesses the minimum value. To achieve this, consider the following approaches:
One common method is to employ the MIN() aggregate function:
SELECT * FROM pieces WHERE price = MIN(price)
However, this query retrieves all records with the same minimum price, providing you with multiple rows. For a more precise result, you can utilize the following:
SELECT * FROM pieces WHERE price = (SELECT MIN(price) FROM pieces)
In this query, the subquery (SELECT MIN(price) FROM pieces) fetches the minimum price from the pieces table. The outer query then selects all records whose price field matches this minimum value.
Here's a practical demonstration using SQLFiddle:
