I have the following data:



7500

9000

1000

10000

2000

3000



When I do an ORDER BY the data above is sorted as follows:



1000

10000

2000

3000

7500

9000



Does anyone know why this is happening?



I need it to sort as follows:



1000

2000

3000

7500

9000

10000





Any help would be much appreciated.
