Hi Jukka,
I have just tried to rename the fields with SQL. Here is the syntax:
"C:\gdal\ogr2ogr.exe" --config OSM_USE_CUSTOM_INDEXING NO -skipfailures -f
"ESRI Shapefile" -dialect sqlite -sql "select geometry, building as bldg,
'building:levels' as bldg_level, height as height from multipolygons"
output_shps input.osm
It raises the following error message:
ERROR 1: In ExecutableSQL<>: sqlite3_prepare<select geometry, building as bldg,
'building:levels' as bldg_level, height as height from multipolygons>:
no such column: height
Interestingly when I convert an .osm file to .shp files without using the SQL
syntax, then the multipolygons.shp file does contain the "height" field. Not
all shapes inside it contain it, but some do.
So why is the upper "no such column: height" error message raised?
Is something wrong with the SQL syntax?
Thank you for the reply.
Kind regards,
Djordje

Hi,
If you select geometry and attribute "foo" that's all you get. If you want
attribute "bar" as well you must do "select geometry,foo,bar from your_table".
That is plain SQL, you will find tutorials from the web.

Thank you Jukka.
I understand now why I need to repeat the same syntax 4 times (by only changing
multipolygon/multilinestrings/lines/points).
Can you explain this part as well please:

?
