Обсуждение: Problem with GeomFromText('POINT(...

I'm trying upate a group of records. In the table I have 1 field geometry and 2 fields ineteger with long. and lat. everyone. I try to update the field geometry with point(long lat).
 
I use this update with numbers and this is ok.

UPDATE
public."Contenedor"
SET
ubicacion = GeomFromText('POINT(1.9845 49.8543)', 4326)

but when i change the number by a field this is not ok. :

UPDATE
public."Contenedor"
SET
ubicacion = GeomFromText('POINT(public.Contenedor.long 49.8543)', 4326) 


I have this error.

ERROR: parse error - invalid geometry
Estado SQL:XX000
Contexto:SQL function "geomfromtext" statement 1

Everyone can tell ma some solution please.
 
Thank you.

The "long" column isn't being referenced the way you've written this,
because its inside of a quoted string.
You need to construct the string
GeomFromText('POINT(' || public.Contenedor.long || ' 49.8543)', 4326)
