Database Table Connector

Source

Creates a database connection to the specified database. Note, this node does only open the connection to read the meta information, but does not read any data at this point.
Make sure you have your vendor-specific database driver registered in the KNIME preference page (section Database Driver). By default, the sun.jdbc.odbc.JdbcOdbcDriver (Windows and Linux) is only available.
