Write Geometries into Database

Write WKT geometries into a database such as a PostGIS database.

Supports the following database types:

Connect PostGIS databases, which run over PostgreSQL databases engines.
Connect MySQL databases
write a H2 databases
write a GeoPackage database files

Depending to the database type you choose, some of the options might not be required and will be disabled in the configuration dialog.

The actual reading is done by the amazing Geotools library.

Options

database type: The type of database you want to connect to: PostGIS, MySQL, H2 or GeoPackage.
hostname: the IP of hostname of the database server
port: the server port (by default 5432)
schema: schema in the database. Defaults to "public"
database: Name of the database. In the case of file-based databases like "h2" or "GeoPackage", you should write here the path to the file containing the database.
user: username for authentication
password: username for authentication
layer: the name of the layer to create
check the results after writing: if checked (default), we read the count of entities written in database to ensure they were written. Uncheck to save a bit of time, once you are sure your data is written correctly in your setting.
