Description

The SHOW command can be used to display information about active connections and database objects.

SHOW CONNECTIONS

If there are no connections, the SHOW CONNECTIONS command returns "No connections available".

Otherwise, the command displays a list of connection names and the URLs used to connect to them. The currently active connection, if there is one, is marked with an * after its name.

Example

ij> connect 'sample' as sample1; ij> connect 'newDB;create=true' as newDB; ij(NEWDB)> show connections; SAMPLE1 - jdbc:derby:sample NEWDB* - jdbc:derby:newDB;create=true * = current connection ij(NEWDB)>

SHOW INDEXES

SHOW INDEXES displays all the indexes in the database.

If IN schemaName is specified, then only the indexes in the specified schema are displayed.

If FROM table-Name is specified, then only the indexes on the specified table are displayed.
