That won't work on a value like "$1.00"

select CAST('$1.00' as decimal(8,2));
+-------------------------------+
| CAST('$1.00' as decimal(8,2)) |
+-------------------------------+
|                          0.00 |
+-------------------------------+
1 row in set, 1 warning (0.00 sec)

| Warning | 1292 | Truncated incorrect DECIMAL value: '$1.00' |
+---------+------+--------------------------------------------+
1 row in set (0.00 sec)


It would have to be something like:

select CAST(REPLACE('$1.00','$','') as decimal(8,2)) ;
+-----------------------------------------------+
| CAST(REPLACE('$1.00','$','') as decimal(8,2)) |
+-----------------------------------------------+
|                                          1.00 |
+-----------------------------------------------+
1 row in set (0.00 sec)


Which in that case, it's better to just select balance without the dollar sign and order on that column.

Regards,
Gavin Towey

Try

order by CAST(Balance as decimal(8,2)) asc;


Cast will work in the order by.
