[gdal-dev] Executing a query getting null layer

[Ahmed Tolba]

My data is in mapserver database which is PostGres PostGIS. What's the equivalent function for st_linefrommultipoint ?

That's no wonder because SpatiaLite does not have such function https://www.gaia-gis.it/gaia-sins/spatialite-sql-latest.html.

Where do you have your data? Are they in PostGIS which has a native support for http://postgis.net/docs/ST_LineFromMultiPoint.html?
