How to Select Data with the Minimum Field Value in MySQL?

Selecting Data with the Minimum Field Value in MySQL

When working with data in MySQL, you may often encounter the need to retrieve records based on the minimum value of a specific field. To achieve this, you can utilize the following steps:

Step 1: Identifying the Minimum Value

To retrieve the minimum value of a field, you can use the MIN() aggregate function. For instance, if you want to find the lowest price from a table called pieces, you would run the following query:

<code class="sql">SELECT MIN(price) FROM pieces;</code>
Copy after login

Step 2: Filtering Records Based on Minimum Value

Once you have identified the minimum value, you can filter your data by selecting only those records where the field in question matches the minimum value. To do this, you can use the following syntax:

<code class="sql">SELECT * FROM pieces WHERE price = (SELECT MIN(price) FROM pieces);</code>
Copy after login

In this query, the subquery (SELECT MIN(price) FROM pieces) calculates the minimum price and the main query SELECT * FROM pieces retrieves all rows from the pieces table that have that minimum price.

By following these steps, you can efficiently select data from a MySQL table based on the minimum value of a specific field.
