Hi all,
I'm using Mapserver version 3.4 and have some problems with the =
expressions in the classes.=20
In my ShapeFile the column is defined as integer, but mapsever doesn't =
recognize it as integer. When I switch to EXPRESSION 1/2/3/4/5/ it =
works. (it seems that mapserver only recoginzes the column as strings). =
Unfortunately I need the integer values.
here is the part of my mapfile=20
LAYER
NAME hausnr_na
DESCRIPTION "gek=FCndigte Wohnungen"
TYPE POINT
STATUS ON
CLASSITEM 'Sig_nbr'
DATA nichtar4
CLASS
NAME "1"
#EXPRESSION /1|2|3|4|5/ # works
EXPRESSION ([sig_nbr] < 6) #works not
SIZE 8
SYMBOL 2
COLOR 255 250 250
END
END=20
cheers,
gernot
