This was just talked about this past week in another thread. I don't believe there is a method for escaping the internal quotes in the SQL statement you show. Possible option(s) would be to add a numeric column to the DB table/view for filtering on. Or make a call that returns more using a different SQL filter and use EXPRESSIONs in the Layer CLASS to filter further for display. This doesn't seem like the economical way to do things things though.
There was some stuff done in recent versions of MapServer though in EXPRESSIONs that may be related. bobb >>> Travis Kirstine <[email protected]> 02/12/09 1:45 PM >>> The following line does not work and I think it has something to do with the single quotes. When I use double quotes Postgres thinks I'm referring to a column name. Is there a way to escape the single quotes? DATA "geom from (select id as oid, geom from some_table where some_field = 'some_string') as myquery using SRID=-1" The following line works because I'm doing a numeric comparison.
