Syntax error Order by number of chars in MySQL?

Order by number of chars in MySQL?

To order by number of chars, use ORDER BY and LENGTH() method. Following is the syntax −

select *from yourTableName
order by LENGTH(yourColumnName) DESC;

Let us first create a table −

mysql− create table DemoTable
   -> (
   -> Name varchar(100)
   -> );
Query OK, 0 rows affected (0.50 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.12 sec)

mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.13 sec)

mysql> insert into DemoTable values('Bob');
Query OK, 1 row affected (0.15 sec)

mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.26 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

This will produce the following output −

+--------+
| Name   |
+--------+
| John   |
| Robert |
| Bob    |
| David  |
+--------+
4 rows in set (0.00 sec)

Following is the query to order by number of chars −

mysql> select *from DemoTable

+--------+
| Name   |

| David  |
| John   |
