Restrictions and Limitations

This section describes the restrictions and limitations when using the DDL operator.

Other Notes

  • The DDL operator is neither a producer nor a consumer operator.
  • The DDL operator is a standalone operator. The DDL operator cannot retrieve data records from the Teradata PT data stream and send them to Teradata. The DDL operator cannot export rows from Teradata.

  • The DDL operator uses one session; it does not support multiple sessions.
  • The DDL operator uses one instance; it does not support multiple instances.
  • By default, if the DDL operator encounters a Teradata Database error, the DDL operator treats the error as a fatal error and terminates the job. You can override this behavior by using the DDL operator's ErrorList attribute.
  • The DDL operator supports every Teradata SQL statement, except statements that return data to the operator, such as the SELECT, HELP, and SHOW statements. There are two exceptions:
  • The CREATE REPLICATION GROUP statement is supported. The user needs the group id and/or the token after a replication group is created.
  • The INSERT...SELECT statement is supported; it returns the total number of rows being inserted in the table.
  • A USING clause cannot be specified with any Teradata SQL statements that end data to the Teradata Database.
  • All data values used by the SQL statements must be hard-coded into the SQL statements.
  • The DDL operator restarts at the beginning of the group of SQL statements whose execution is interrupted by an abnormal termination.
  • The DDL operator can send SQL statements up to 1MB to Teradata Database.
  • The DDL operator does not require a Teradata Database load slot.
