Using sling conns

Here are examples of setting a connection named EXASOL. We must provide the type=exasol property:

$ sling conns set EXASOL type=exasol host=<host> user=<user> password=<password> port=<port> schema=<schema>

# With additional parameters
$ sling conns set EXASOL type=exasol host=<host> user=<user> password=<password> validate_server_certificate=true encryption=true

# OR use url
$ sling conns set EXASOL url="exasol://myuser:[email protected]:8563/myschema?validate_server_certificate=true&encryption=true"
