How Can I Customize the Decimal Separator in MySQL Output?

Custom Decimal Separator Configuration in MySQL

MySQL typically uses a dot (.) as the decimal separator in its output. However, some scenarios may require a different character, such as a comma (,), to be used as the separator. This article explains how to modify this setting without altering your existing queries.

To change the decimal separator in MySQL output, it's important to note that direct modification of MySQL's core settings is not recommended. However, you can achieve this by leveraging specific character conversion functions or third-party tools.

One possible method involves using the REPLACE() function to replace the dot with the desired character. For instance, the following query will replace the decimal dot with a comma in the prijs_incl column:

SELECT REPLACE(CAST(prijs_incl AS CHAR), '.', ',')

This technique allows you to manipulate the output data without affecting the underlying values. It can be particularly useful in situations where comma-separated values (CSVs) need to be exported to spreadsheets compatible with European formats that expect commas as decimal separators.
