[Mapserver-users] null values in postgis

[Kathi Koebke]

Hello,

does anybody know about problems displaying null values in mapserver ? I 
'm working with Postgresql/postgis and I have emtpty fields (missing 
values) in my tables.
I want to classify the data and I have to display missing values in my 
map.  EXPRESSION ([ha_ges] is null) did not work .
Any Ideas?!
Thanks Kathi Köbke
