Abstract
Arrangements for a reading scheme for column-oriented databases are provided. A virtual column may be generated by applying a structured query language operation on distinct values in a column of data in a table. Based on applying the structured query language operation, the virtual column may be populated with corresponding precalculated values. The virtual column may be compressed with dictionary-based compression. The compressing may include generating a column of value identifiers, each of the value identifiers representing a distinct value in the column of data. A database query against the compressed virtual column may be received. A result of the database query may be returned by retrieving one or more of the precalculated values from the compressed virtual column.
