Method and system for organizing values of alternative equality conditions |
摘要 |
A method, computer program, and computer network are disclosed for organizing values of multiple alternative equality conditions between a database column and a set of values. The method includes applying a function to each value to obtain a result for each value. The values are organized into groups where each group includes values with the same result. The values are stored according to the groups. A computer program or database system executes queries that include multiple alternative equality conditions between a database column and a set of values. The database system also includes an optimizer that is configured to apply a function to each value to obtain a result for each value. The values are organized into groups where each group includes values with the same result. The values are stored according to the groups.
