I have the following layer defined in a mapfile:


                NAME "aggregates"
                #STATUS OFF
                TYPE POLYGON
                CONNECTION "host=localhost port=5432 dbname=*** user=*** password=***"
                DATA "geom FROM (SELECT b.geom AS geom, a.peril_id, a.portfolio_id, a.tiv, a.thematic_tiv, a.aggregates_id FROM schema.aggregates a INNER JOIN gisdata.adm_1 b on a.gid = b.gid) AS c using SRID=4326 using unique aggregates_id"



This works in Mapserver 6.4. However, when I try to use this with Mapserver 7, I get the following errors logged when I try to generate tiles:

            [Wed Jun  7 03:42:43 2017].502983 msDrawMap(): rendering using outputformat named png (AGG/PNG).

I'm sure something's changed in the way I'm supposed to configure the mapfile, but I can't figure out what it is.

EDIT: I've tried eliminating the joins by creating a table with all the necessary data. In this case, I have:

            DATA "geom from portfolios.area_aggregates_join using SRID=4326 using unique aggregates_id"

Yet I still get the same error. That "and ()" at the end of the final query that's causing the syntax error is bothering me.

  • Are you sure that is the query that is failing. Your debug output doesn't seem to match. For example in your debug output "thematic_tiv" is the only field that shows up. Only thing I can think of that might be an issue is if you are passing in params. I don't see that though but I think you'd need to put in validation for them - see mapserver.org/cgi/runsub.html

  • It appears to me that the debug output matches. I'll take a look at the link you provided. Thanks. Jun 7, 2017 at 6:18

I figured this out. The mapfile wasn't the only thing influencing the rendering of tiles, there were also modifications to the configuration through PHP and Mapscript.

Whereas in Mapscript 6.4 I could do the following:


I had to do this in Mapscript 7.0.5:


Thank you for the question and the hint in your answer. I am also searching for the error you posted but without MapScript. But I also got the feeling that it has something to do with the FILTER resp missing FILTER Parameter in my Postgis-Layer ... syntax error at or near ")"
