Abstract
A database system receives a transaction specifying one or more conditions to apply to a first table, and inserts data selected in the transaction into a second. The database system further generates a value list used for compressing a column of the second table, where generating the value list comprises one of inheriting entries of the value list from another value list associated with the first table, and deriving the value list based on the one or more conditions to apply on the first table.
