How do I sort numbers saved as VARCHAR in MySQL with some of them having preceding 0 like 085, 090, etc.?
Following is the syntax −
select *from yourTableName order by yourColumnName*1,yourColumnName;
Let us first create a table −
mysql> create table DemoTable ( Value varchar(100) ); Query OK, 0 rows affected (0.62 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('90');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable values('86');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable values('45');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('85');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable values('085');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('090');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('045');
Query OK, 1 row affected (0.10 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+ | Value | +-------+ | 90 | | 86 | | 45 | | 85 | | 085 | | 090 | | 045 | +-------+ 7 rows in set (0.00 sec)
Following is the query to sort numbers saved as VARCHAR with some of them having to precede 0
mysql> select *from DemoTable order by Value*1,Value;
This will produce the following output −
+-------+ | Value | +-------+ | 045 | | 45 | | 085 | | 85 | | 86 | | 090 | | 90 | +-------+ 7 rows in set (0.00 sec)
