Hello QGIS-community,
We are quite new to working with PostGIS in QGIS 3.2.0, so we have some
usability-questions…
In the Autodesk world (don't hit me 😉) there is a feature called
"create object from geometry".
What it does, is to create a new database-object from an existing
selected geometry. After creating the object
you enter the attributes needed and commit it to the database.
Is there any similar feature in QGIS? Is there any possibility to
conviniently copy db-objects from table to table?
I think you can set that db layer to editable and then copy-paste
selected features from other layers to it. Attributes with the same
field name and type will be copied, others you can enter by manually
afterwards.
We tried db-manager, but it was just good for importing/exporting data,
though it's possible to import data from a temporary Qgis layer.
But then we have problems with shortened attribute names in our
temporary layers.
So, is there any way to get/preserve long attribute-names in analysis?
For ex. If we use "union" or
"intersect" our input-attributes (from PostGIS) are shortened to
shape-file-limit (10 characters?) thus it's quite time-consuming
to get data back into the database.
Don't use shapefiles for this, that is where the fild name length limit
is. Try a memory layer instead. Or if you need to save is, try
geopackage (gpkg).
Thx for your worthy hints, best regards from switzerland.
Good luck and regards from The Netherlands! :)
