The following example alters a column named qty_shipped_2006 in the customer table and makes that column uncompressible using multivalue compression. The column qty_shipped must already be defined for customer because you do not specify a data type for it. In that case, Vantage interprets the ADD specification to represent a request to modify an existing column.

     ALTER TABLE customer ADD qty_shipped_2006 NO COMPRESS;
