How to format number with “.” as thousand separators, and “,” as decimal separator?

You can use format() function for the separators. It will work in MySQL version greater than or equal to 5.5. We are using the version 8.0.12

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.12    |
+-----------+
1 row in set (0.00 sec)

The syntax is as follows

SELECT FORMAT(yourColumnName, valueAfterDecimalPoint, 'de_DE') AS anyAliasNamefrom yourTableName;

To understand the above syntax, let us create a table. The query to create a table is as follows

mysql> create table formatNumberDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> Number DECIMAL(19,1)
   -> );
Query OK, 0 rows affected (1.13 sec)

Insert some records in the table using insert command.

The query is as follows

mysql> insert into formatNumberDemo(Number) values(10000000000000.2);
Query OK, 1 row affected (0.15 sec)
mysql> insert into formatNumberDemo(Number) values(1000.4);
Query OK, 1 row affected (0.21 sec)
mysql> insert into formatNumberDemo(Number) values(1000000.6);
Query OK, 1 row affected (0.11 sec)
mysql> insert into formatNumberDemo(Number) values(100000000.7);
Query OK, 1 row affected (0.17 sec)
mysql> insert into formatNumberDemo(Number) values(100000000000000000.8);
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement.

The query is as follows

mysql> select *from formatNumberDemo;

The following is the output

+----+----------------------+
| Id | Number               |
+----+----------------------+
| 1  | 10000000000000.2     |
| 2  | 1000.4               |
| 3  | 1000000.6            |
| 4  | 100000000.7          |
| 5  | 100000000000000000.8 |
+----+----------------------+
5 rows in set (0.00 sec)

Here is the query to format number with '.' as thousand separator, and ',' as decimal separator

mysql> SELECT FORMAT(Number, 3, 'de_DE') AS Numberformat from formatNumberDemo;

The following is the output

+-----------------------------+
| Numberformat                |
+-----------------------------+
| 10.000.000.000.000,200      |
| 1.000,400                   |
| 1.000.000,600               |
| 100.000.000,700             |
| 100.000.000.000.000.000,800 |
+-----------------------------+
5 rows in set (0.00 sec)
