[mapserver-users] Expression and nquery with sde issue

Fri Jul 15 07:38:55 PDT 2011

The version is Mapserver 5.6.3 and using the attribute as label was how 
find out the values were being rounded.
For example the attribute has values from 1000 to 170000 and if the 
value is smaller than 100000 rounds the value with one decimal but above 
100000
rounds to and integer.
I'm using sqlserver with the SDE and the atrribute type is numeric could 
this have anything to do with it?
