Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for expressing inequality expressions as a bounded number of equality expressions. One of the methods includes receiving an original query having an inequality expression for an original attribute. A new query that replaces the inequality expression with a bounded number of equality expressions is generated, wherein each equality expression references a respective auxiliary attribute, each auxiliary attribute representing intervals of values for the original attribute. The new query having the bounded number of equality expressions is provided to a database system instead of the original query. Query results that satisfy the inequality expression for the original attribute are received from the database system.
