Teradata Database supports bulk SQL error handling for MERGE and INSERT . . . SELECT statements. This permits bulk SQL inserts and updates to be done without the target table restrictions that apply to Teradata Database load utilities.
Load utilities are restricted from unique indexes, join or hash indexes, referential constraints, triggers, and LOBs on the target table.
USI and referential integrity (RI) violations cause the request to abort and rollback after all these violations and all other supported error conditions are logged.
For information on creating and dropping the error table, see Teradata Vantage™ SQL Data Definition Language Detailed Topics , B035-1184 .
