Restrictions on Load Utilities
You cannot use FastLoad, MultiLoad, or the Teradata Parallel Transporter operators LOAD and UPDATE to load data into base tables that have join indexes because those indexes are not maintained during the execution of these utilities. If you attempt to load data into base tables with join indexes using these utilities, the load operation aborts and the system returns an error message to the requestor.
To load data into a join-indexed base table, you must drop all defined join indexes on that base table before you can run FastLoad, MultiLoad, or the Teradata Parallel Transporter operators LOAD and UPDATE.
Be aware that you cannot drop a join index to enable MultiLoad or FastLoad batch loads until any requests that access that index complete processing. Requests place locks on any join indexes they access, and the system defers processing of any DROP JOIN INDEX requests against locked indexes until their locks have all been released.
Load utilities like Teradata Parallel Data Pump, BTEQ, and the Teradata Parallel Transporter operators INSERT and STREAM, which perform standard SQL row inserts and updates, are supported for join‑indexed tables, as are multirow INSERT … SELECT and MERGE requests.
