How to export ogr2ogr patterns to SQL Server?
The following code exports data from the OGRExportTable in the localhost\\sqlexpress SQL Server instance to an ESRI Shapefile called c: emp\\sqlexport_linestring.shp . ESRI Shapefiles can only contain features of a single geometry type.
How is geometry data assigned in ogr2ogr?
The geometry data is assigned the projected SRID EPSG:2249 (assumed to be the SRID in which the source data is supplied, but this is not checked by OGR2OGR). The following code listing takes data from the precincts.shp ESRI shapefile and loads it into the sql2012 SQL Server instance running on localhost .
What to do with double quotes in ogr2ogr?
If you do use double quotes, you should use “straight quotes”, and not “smart quotes”. After importing any data, OGR2OGR will create two additional tables in your SQL Server database – spatial_ref_sys and geometry_columns, which store metadata about the spatial columns in the tables.
What is the difference between GDAL and OGR?
While GDAL itself deals with raster data – GeoTIFFs, ECW, DEMs and the like – its sister project, OGR, deals with vector data formats such as ESRI Shapefiles, MapInfo, KML, or SQL Server geography/geometry data. The OGR2OGR utility is the specific GDAL/OGR component for transforming data between these different vector formats.
How to execute a SQL statement in GDAL?
-sql sql_statement: SQL statement to execute. The resulting table/layer will be saved to the output. Starting with GDAL 2.1, the syntax can be used to indicate that the content is in the pointed filename. If I understand correctly the command is in the file, so you will need to read that file to get the text.
How is OGR used to import non-spatial data?
Using OGR to Import Non-spatial Data While OGR was designed primarily to transform data between different spatial datasources, it is a little known fact that it can be used as well for importing non-spatial datasources such as Dbase files and CSV files. Importing Dbase file into PostgreSQL using Ogr2Ogr
How to export multiple PostGIS tables in ogr2ogr?
One way in which ogr2ogr excels above using the pgsql2shp tool is that ogr2ogr can export multiple tables at once. This is pretty handy for sharing your postgis data with others who do not have a postgis database. The code below will export all your postgis tables out into a folder called mydatadump in ESRI shape (shp) format.
How to export spatial data from SQL Server?

How to export shapefile from SQL Server to Esri?
Around another 200 people have come here after searching for variations and combinations on this theme, including “OGR2OGR Sql Server”, “OGR2OGR MSSqlSpatial”, “OGR SQL”, “OGR Import shapefile” etc. What I’m not sure, though, is how to interpret this statistic or best act upon it.
Why is shapefile not importing in SQL Server?
The problem is that the current version of QGIS (GDAL version is the real problem) has a bug and it doesn’t create the geography\\geometry column in MSSQL… Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
Can you use OGR SQL instead of SQLite?
SQL dialect. In some cases can be used to use (unoptimized) OGR SQL instead of the native SQL of an RDBMS by passing OGRSQL. Starting with GDAL 1.10, the “SQLITE” dialect can also be used with any datasource.
