Dropping SECONDARY INDEX in a Teradata table
to drop the named secondary indexes,
Syntax:
drop index index_name on table_name;
to drop unnamed secondary indexes, just reference the column combination,
Syntax:
drop index (emp_id,dept_id) ON happy_employees;
Dropping a secondary index automatically drops the sub-tables and speeds up the data loads.
