Thank you Thomas, Sorry I didn't make it clear that I'm using the shapefile as data source. I tried as you suggested but it's not working.
The document about DATA of the layer in mapfile is: DATA [filename]|[sde parameters][postgis table/column][oracle table/column]. So I think it's not supported in MapServe to filter columns of the shapefile... Maybe I need to write some code. I don't know. Do you have any suggestion where to start or there is another solution? Thanks again.
