Executing SQL statement like
Drop error table for TableX; Alter TableX Add COLUMN_NAME varchar(20);
Results in an error:
Drop Error: Falied 3932: Only an ET or null statement is legal after a DDL statement
Executing it line by line works fine but as an entire SQL statement it causes this error message.
Anyone has an explanation for this perhaps?
Teradata requires that a DDL statement be the last/only statement in a unit of work - it must be committed before any additional statement can be submitted.
And a multi-statement request is implicitly a unit of work.
