Column set on which the index is to be ordered.

If you specify ORDER BY VALUES, then you can specify only one column for column_name_3.

The specified column set must be a subset of column_name_1.

You cannot specify the system-derived columns PARTITION or PARTITION#L n in the column name list. However, you can specify a user-defined column named partition or partition#L n, where n ranges from 1 through 62.

You cannot specify the same column twice in the column_name_3 list.

You cannot compress column values for a hash index.

You cannot order an index by a Period, BLOB, CLOB, LOB UDT, Geospatial, VARIANT_TYPE, or ARRAY/VARRAY column.
