closes the Driver Module
Close frees the resources associated with driver. This also happens when the resources are freed via garbage collection; however, you can call Close to release the resources immediately.
Any descendant modules of driver are closed when driver is closed. (A module is a descendant of driver if it is returned by one of driver's exports or is a descendant of one of driver's descendants.)
Load the JDBC driver and open a connection to the database.
driver ≔ DatabaseLoadDriver⁡'driver'=com.database.Driver,'classpath'=/path/to/jar/jdbc.jar:
conn ≔ driver:-OpenConnection⁡jdbc:dbdriver://localhost/DBName,user1,passwd,'isolation'='serializable':
Close the driver.
Try to use the connection.
conn:-ExecuteQuery⁡SELECT * FROM datatable
Error, (in ExecuteQuery) this object has been closed, no further operations are possible
Try to use the driver.
conn ≔ driver:-OpenConnection⁡jdbc:dbdriver://localhost/DBName,user1,passwd,'isolation'='serializable'
