The node data type for querying hierarchical data

The node data type is an opaque type of variable length up to 256 characters.

The Scheduler must be running in the database server. If the Scheduler is not running when you create a node data type, a message that the data type is not found is returned.

The database that contains the node data types must meet the following requirements:

  • The database must be logged.
  • The database must not be defined as an ANSI database.

If you attempt to create a node data type in an unlogged or ANSI database, the message DataBlade registration failed is printed in the database server message log.

Operations involving Enterprise Replication are supported.

Deep copy and LIKE matching statements are not supported.
