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 hash indexes because those indexes are not maintained during the execution of these utilities. If you attempt to load data into base tables with hash indexes using these utilities, the load operation aborts and the system returns an error message to the requestor.
To load data into a hash-indexed base table, you must drop all defined hash indexes on the table before you can run FastLoad, MultiLoad, or the Teradata Parallel Transporter operators LOAD and UPDATE.
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 hash‑indexed tables.
