Re: sort question

I don't know if this is a JDBC thing or not, but if I issue this
query:

select distinct style, color, width, size from skiddata
where skidno = 'F3932' order by style, color, width, size;

I get the sizes in order '10 ', '10-', '11 ', '12 ', ' 9 ',
' 9-'. Shouldn't ' 9 ' and ' 9-' come first? Have I got
something set up wrong in Postgres?

I'm using Postgres 7.3.2 on SuSE Linux 8.2 (kernel 2.4.20), driver
pg73jdbc3.jar.

Glenn,

How come there are spaces in there? ' 9 ' ?

what happens if you trim(sizes) ?

It is not.

Text fields are sorted textually. If you want a numeric sort, use a
numeric data type.
