For me, I'am using this way to display a label with three lines, containing the
point name and its x,y coordinates, here is the query:
SELECT
"t_0"."ogc_fid",
"t_0"."wkb_geometry",
'Ponto '||"t_0"."ponto" ||'\n'||
'x='||CAST(ROUND(CAST(ST_X("t_0"."wkb_geometry") as numeric),0) as varchar)
||'\n'||
'y='||CAST(ROUND(CAST(ST_Y("t_0"."wkb_geometry") as numeric),0) as varchar)
FROM "elektro"."pontos_arvores" AS "t_0"
But I want to make changes, like, add another line with more info, or change
the word 'Ponto' to uppercase.To do that, I create another layer and delete the
old one.
For now, it's the only way?
Regards.
Pablo. _______________________________________________
