摘要：
An approach is provided that receives an alteration request to mark a selected column in a database table as an unused column. A database control table is then updated to indicate that the selected column is unused. After the database control table is updated, when a read request is received for the selected column, the same data is returned for the selected column for each row being read and this data is not stored in the database table.
