Hi, I am not familiar with SQL server but your table name may require quotation marks " " and they require escaping with \ so that they do not close the SQL statement. Try -sql "update \"table_name\" set …. "
Simple test to verify if the problem is caused by the unquoted table name is to run ogrinfo with -sql "select * from table_name limit 1". -Jukka- Lähettäjä: Hector muro <muro.hec...@gmail.com> Lähetetty: keskiviikko 2. joulukuuta 2020 12.13 Vastaanottaja: Rahkonen Jukka (MML) <jukka.rahko...@maanmittauslaitos.fi> Kopio: gdal-dev@lists.osgeo.org Aihe: Re: [gdal-dev] ogr2ogr project/transform CRS in the same database table Hi again, I've given your idea a go: ogrinfo -dialect sqlite -sql "update <table_name> set <text_geom> = ST_AsText(ST_Transform(geometry),4326)" --config MSSQLSPATIAL_USE_GEOMETRY_COLUMNS NO "$connect_string" This connects correctly, as I get this message: INFO: Open of `MSSQL:server=xxx;database=xxx;UID=xxx;PWD=xx;DRIVER=ODBC Driver 17 for SQL Server' using driver `MSSQLSpatial' successful. But it can't read/find the table in the update statement: ERROR 1: In ExecuteSQL(): sqlite3_prepare_v2(update <table_name> set <text_geom> = ST_AsText(ST_Transform(geometry),4326)): no such table: <table_name> (I have tried different versions of the table name, quoting, unquoting, adding the Schema name . table name, with the same results.) I now wonder if the sqlite dialect can't really read what's inside my SQL Server instance? Is it maybe too much what I am trying to do? (too much for SQL Server's limitations).

You did not tell what is your database so I can't tell the exact recipe for you but you will learn it. You need to know that there are different SQL dialects for GDAL: OGR SQL, SQLite, indirect_SQLite, and the native SQL for your database. They are all documented. If your database does not have native ST_Transform support then you take it from SQLite/Spatialite. For overriding the native SQL of your database you may need to use -dialect indirect_SQLite. Here is another example with a shapefile. A combination of OGR SQL and SQLite dialects is needed. Add a new column ogrinfo -sql "alter table states add wkt_geom text" states.shp There is space for only 254 charactes in a shapefile and that is not enough for big polygons but we can do at least something with a little trick. ogrinfo -dialect sqlite -sql "update states set wkt_geom=ST_AsText(ST_Transform(ST_Centroid(geometry),3857))" states.shp Check what we got ogrinfo states.shp -al ...
