Helo,

If field is a varchar or char you are comparing string values not
integer values:

in alfabetical order '1000' is less than '999' since '1' comes first
then '9'

try to cast the value to integer if you wish or store your values left
padded with 0s like
'0999'
'0001'
'1000'

Anyway why store a char value if you want to compare it as numbers ?

See you !
