DELETE DATABASE and Error Tables
When you delete a database that contains an error table, the system drops the error table regardless of the containing database for its data table. The system also drops the rows for the error table in the DBC.ErrorTbls system table (see Data Dictionary).
You cannot delete a database that contains a data table with an error table that is contained by another database. Otherwise, the system aborts the request in Teradata session mode or the transaction in ANSI session mode and returns an error to the requestor.
The remedy for this situation is as follows:
1 Find all the error tables that are defined on the tables in the database being deleted by using the following SELECT request:
SELECT BaseTblDbName, BaseTblName, ErrTblDbName, ErrTblName
WHERE BaseTblDbName <> ErrTblDbName
AND BaseTblDbName = CurrentDBName;
where CurrentDBName is the database name of the database being deleted.
2 Drop all error tables from the list produced by this query.
3 Resubmit the DELETE DATABASE request.
