jdbc
Usage: :jdbc:<jdbc-part>
Interacts with the JDBC system
(JDBC sort-of stands for Java DataBase Connectivity)
to execute an SQL query on a connected database.
The jdbc:... specification is the JDBC URL.
For historical compatibility reasons,
specifications of this scheme
may omit the leading colon character,
so that the following are both legal, and are equivalent:
jdbc:mysql://localhost/dbl#SELECT TOP 10 ra, dec FROM gsc :jdbc:mysql://localhost/dbl#SELECT TOP 10 ra, dec FROM gsc
In order for this to work, you must have access to a suitable database with a JDBC driver, and some standard JDBC configuration is required to set the driver up. The following steps are necessary:
jdbc.drivers system property must be set
to the driver classname
More detailed information about how to set up the JDBC system to connect with an available database, and of how to construct JDBC URLs, is provided elsewhere in the documentation.
