According to an embodiment, a plurality of target operators are identified that include a common expression. Each respective target operator corresponds to a step that evaluates the common expression during query execution. The plurality of target operators are modified to enable sharing of an evaluation result of the common expression. The query is executed according to the target operators. During query execution, the evaluation result is shared by the target operators. In other embodiments, the evaluation of the common expression is pushed to a storage layer. During query execution, a database management system retrieves the evaluation result of the common expression from the storage layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus of shared expression evaluation across RDBMS and storage layer","description":"Techniques are provided for sharing expression evaluation across a database management system and a storage layer.
