When I use a parameter to filter columns dynamically, the query executes correctly, and the database returns what I expected.
SELECT ST_AsBinary(geometry) AS geometry, id, collection_id, $1
FROM table_features WHERE geometry && ST_MakeEnvelope(-63.7,-31.61,-63.72,-31.57,4326)
AND collection_id = $2 with args [elevation my_uuid_collection_id]
My params config:
[[maps.params]]
name = "param"
token = "!param!"
type = "string"
sql = ",?"
[[providers.layers]]
name = "table_features"
geometry_fieldname = "geometry"
geometry_type="GeometryCollection"
id_fieldname = "id"
sql = """SELECT ST_AsBinary(geometry) AS geometry, id, collection_id !param!
FROM table_features WHERE geometry && !BBOX! !COL!"""
When I used a parameter (for example !param!) in the query selct in the response I got something similar to this:
?column?:"elevation"
However, when I detail the column directly, the select is executed in the same way but I correctly obtain something similar to this:
[[providers.layers]]
name = "table_features"
geometry_fieldname = "geometry"
geometry_type="GeometryCollection"
id_fieldname = "id"
sql = """SELECT ST_AsBinary(geometry) AS geometry, id, collection_id, elevation
FROM table_features WHERE geometry && !BBOX! !COL!"""
