Hi,
I have road layer and segment the road where bridge exist by a field
'bridge' =T in road layer.
I am able to count number of bridges using
count("bridge", filter:="bridge"='T').
How to count the number of bridges on selected roads?
Any clue?

[QGIS-it-user] Unione punti tramite GID e file csv
Buonasera a tutti, Vorrei sapere se è possibile in qgis unire con un segmento coppie di punti avendo a disposizione uno shape in cui ogni punto ha un GID e un file csv che contiene le coppie di punti da unire GID_a e GID_b; Ogni punto GID_a può essere collegato a diversi punti GID_b (ma non viceversa) Ad esempio: il GID 001 deve collegarsi a 101,102,103 Il GID 002 deve collegarsi a 103,104,106,107,108,109,110 Il GID 003 deve collegarsi a 111,112 Il GID 004 deve collegarsi a 113 (solo che un gid é qualcosa tipo 2784932498734) Utilizzo ancora il qgis 2.18.11 ma se necessario posso passare a versioni più recenti Ringrazio tutti per la disponibilità Cordiali saluti Giorgio ___ QGIS-it-user mailing list QGIS-it-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/qgis-it-user
Re: [Qgis-user] Keypress event and slowless
*Jésahel Benoist* /Wed Aug 3 04:33:23 PDT 2022/ maybe to be able to know what events are triggered to try to correct this, because it could be a plugin or a calculated field or anything. Hi Jésahel, have you tried if the issue occurs also using a new QGIS user profile without any external plugin installed? Best regards.

Re: [Qgis-user] Keypress event and slowless
I have been experiencing the same problem. It seems to occur when there are a lot of elements in the map. Very painful experience. And I agree that it seems like it shouldn't need to be calculating while you are typing.

[QGIS-it-user] Query lente in postgis su tabella puntuale
Ciao a tutti,
ho un problema con qgis server che finora ha funzionato benone:
appena accendiamo il server e iniziano le chiamate wms (che arrivano da
mapproxy in locale) la cpu viene saturata da query di questo tipo
SELECT count(distinct ("id","campo2"))=count(("id","campo2")) FROM
"public"."nometabella" WHERE st_srid("geometry")=4326 AND
upper(geometrytype("geometry")) IN
('POINT','POINTZ','POINTM','POINTZM','MULTIPOINT','MULTIPOINTZ','MULTIPOINTM','MULTIPOINTZM')
che dopo un attesa interminabile risponde semplicemente TRUE,
nometabella ha circa 1,7 milioni di righe con geometria POINT ed è
partizionata in 102 tabelle figlie. postgres 12 postgis 3.2 sembra che
cerchi se le geometrie sono coerenti tra le tabelle partizionate...
Pare che ad ogni processo fastcgi venga rilanciata,,, avete idea del perché
e se ci sono configurazioni di postgis o di QGIS che possono evitare di
ripetere così spesso questo check?

[Qgis-user] Keypress event and slowless
Hi, On Windows/QGIS 3.16/QGIS 3.22 LTR, am I the only one having noticed some annoying slowness in big projects when typing ? It happens especially in layout when changing a legend element name or in the attribute table. What is really annoying is that each keypress seems to trigger some heavy calculation. I think it should only happen when exiting the field, or maybe to be able to know what events are triggered to try to correct this, because it could be a plugin or a calculated field or anything.
