1. A method comprising: receiving a database query which references a column within a table, wherein a column cell value from the column is represented using an enumeration value and a lookup-table configured to translate the enumeration value into the column cell value; generating a set of query processing steps that, when executed by one or more processors, provide a query result to the query; creating a secondary enumeration value, based on a determination that usage of the enumeration value does not produce an equivalent result to usage of the column cell value within a query processing step of the set of query processing steps, such that substitution of the secondary enumeration value within the query processing step of the set of query processing steps does produce an equivalent result to usage of the column cell value from the column within the query processing step; and creating a mapping from the enumeration value and the column cell value to the secondary enumeration value.
