Drop Index: Teradata vs Oracle Syntax

Teradata

Syntax:

DROP INDEX index_name ON tablename;
--or
DROP INDEX(column1, column2, ..., columnN) ON tablename;

Example 1:

Dropping index named idx_dept from employee.

DROP INDEX idx_dept ON employee;

Example 2:

Dropping an index that is not named. The following drops the index on (dept_number, emp_number) columns in the employee table:

DROP INDEX (dept_number,emp_number) ON employee;

Oracle

Syntax:

DROP INDEX idx_dept;
