ORA-01408
        such column list already indexed
        
        
        Cause
        A CREATE INDEX statement specified a column that was already indexed. A single column may be indexed only once. Additional indexes may be created on the column if it was used as a portion of a concatenated index, that was, if the index consists of multiple columns.
        Action
        Do not attempt to re-index the column, as it is unnecessary. To create a concatenated key, specify one or more additional columns in the CREATE INDEX statement.
