Either alter the table to make that field an INTEGER column, or "ORDER
BY field+0" to force mysql to internally convert the field to a number
before sorting.

RE: Basic Q's: Numerical Sorting

2002-07-09 Thread Luc Foisy

Here is the solution I posted about t months ago. I would also add, this solution can 
handle both text and numbers in the same field...:

my boss figured out a nice solution to this

ORDER BY IF(ABS(Item) > 0,LPAD(Item,9,'0'),Item)

This will pad numbers ( ok it might not do so hot with DECIMAL, but it can be fixed to 
work I supposed) with 0

So it should sort 

1
2
00010
00022
00050
00230

instead of

1
10
2
22
230
50

And it will skip padding text cause I guess the ABS of text is 0, and the "numbers" 
and words will appear separated from each other

My boss is smart :)

Re: Basic Q's: Numerical Sorting

It looks like your field is a text field rather than BIGINT or some
numerical field.  Changing the field type should solve your problem.
