Great !! it works.
BTW , actualy I want something like --> level in ('0' , '1' , '2' , '3'
, '4')
means that the compared values is "varchar" .

I think I can't use "PropertyIsBetween" , since the compared values is
not "integer" ?
Again ....
My data Is a PostGis ,
It have varchar coloumn called 'level' with values in --> '0' , '1' ,
'2' , '3' , '4'
My goals is to display the data with spesific value or values at
specific "zoom" level.
The Postgis data is imported from community developed Garmin map img
file ... thats why it have a 'level' values between 0-4 ... but it's
imported (by:shp2pgsql) as VarChar.
I also tried to create a pgsql view for each level ... in hope that
it'll speed up the rendering process.
But I still fuzzed by how to calculate the ScaleDenominator.
Sincerely
